The sole question presented by this appeal is whether the trial judge erred in granting defendants’ motion for a directed verdict.
 It is the duty of a bailor for hire to see that the vehicle bailed is in good condition. While he is not an insurer, he is liable for injury to the bailee or a third person for injuries proximately caused by a defect in the vehicle of which he had knowledge or which he could have discovered by reasonable care and inspection. Hudson v. Drive It Yourself, Inc., 236 N.C. 503, 73 S.E. 2d 4.
[2, 3] A motion for a directed verdict presents the question of whether, as a matter of law, the evidence offered by plaintiff, when considered in the light most favorable to the plaintiff, is sufficient to be submitted to the jury. Kelly v. Harvester Co., 278 N.C. 153, 179 S.E. 2d 396. The court may direct a verdict against the party having the burden of proof when there is no evidence in his favor. Cutts v. Casey, 278 N.C. 390, 180 S.E. 2d 297.
We deem it unnecessary to discuss plaintiff’s allegation that defendants left rocks or other objects dangerous to golf carts on the golf course, since he offered no direct evidence which *54would support an inference that any objects of a dangerous nature were present on the golf course.
Plaintiff contends that his injury was caused by defective brakes on the golf cart and that defendants knew, or by the exercise of reasonable care should have known of the defect. In this connection plaintiff’s evidence shows that the brakes on the golf cart could fail in two ways, viz: (1) sudden failure caused by the snapping of the brake cable, and (2) gradual failure of the brakes caused by wear on the linings of the brake bands.
Plaintiff’s expert witness testified concerning sudden failure of the brakes as follows: “In order to sever this cable or cause this cable to break it is going to take a lot. There would be practically no way to break it, in normal driving around, suddenly, unless the cable, I’d say, is four to five years old and worn a lot, you can’t break it, not with a foot.” Plaintiff’s evidence showed that the golf cart in which plaintiff was injured was not more than one year old.
As to the gradual failure of the brakes, plaintiff’s evidence showed that a visual inspection would reveal the wear on the linings of the brake bands, and that an annual inspection would be reasonable.
Plaintiff’s evidence failed to show that the cable snapped or that the linings on the brake bands were worn.
We quote the following excerpts from plaintiff’s testimony:
Q. What, if anything, did Mr. Shumate say to you?
Mr. Minor: Objection.
The Court: Well, I don’t know what he is going to say. I guess at this point I will admit it as against Shumate and not the others. I don’t know what he is going to say. Sustained as to, well, as to the corporate defendant, I reckon I will say.
. . . Then the park manager came up — I assume that he was the park manager; I never did see the gentleman because of the way that I was lying — and Mr. Shumate told him—
*55Mr. Minor: Well, objection now, if the Court please.
The Court: Well—
Mr. Minor : He is talking about someone he doesn’t know about.
The Court: Sustained again as to the corporate defendant, Tanglewood Park, Go ahead.
. . . Later Mr. Shumate came back to me and he says, “If you are familiar with these carts, you should know that they have no brakes on them going backwards.” I was still lying on the ground at that time, sir.
Mr. Powell: I submit that statement is competent against the corporate defendant as well as Mr. Shumate.
The Court: Well, of course, he has got an exception to all this. I will let that in.
Plaintiff strongly contends that this statement was sufficient evidence of defendants’ negligence to carry the case to the jury.
Plaintiff failed to allege that defendants rented the golf cart knowing that it had no brakes when going backward. We must therefore decide the effect of this variance in the allegations and proof.
 Prior to the adoption of the new Rules of Civil Procedure it was well recognized that a plaintiff’s recovery had to be based on allegations in his complaint, and that when there was a material variance between allegations and proof, nonsuit was proper. Conger v. Ins. Co., 266 N.C. 496, 146 S.E. 2d 462; Andrews v. Bruton, 242 N.C. 93, 86 S.E. 2d 786. No issues were submitted to the jury which were not raised by the pleadings and supported by competent evidence. Bowling v. Bowling, 252 N.C. 527, 114 S.E. 2d 228. A motion for nonsuit is no longer proper in a civil action. In an action tried by the court without a jury, a defendant may move for a dismissal on the ground that upon the facts and the law plaintiff has shown no right to relief. Ch. 1A-1, Rule 41(b). When a case is tried by a jury, as here, a defendant may move for a directed verdict to test the sufficiency of the evidence to go to the jury. Ch. 1A-1, Rule 50(a). See Kelly v. Harvester Co., supra.
*56  By enactment of G.S. 1A-1, the legislature adopted the “notice theory of pleading.” Under “notice pleading” a statement of claim is adequate if it gives sufficient notice of the claim asserted “to enable the adverse party to answer and prepare for trial, to allow for the application of the doctrine of res judicata, and to show the type of case brought. Sutton v. Duke, 277 N.C. 94, 176 S.E. 2d 161.
 The North Carolina pleadings and forms differ from the federal pleadings and forms in that federal Forms 9 and 10, complaints for negligence, do not require specific allegations of acts of negligence. Under Rule 84 of G.S. 1A-1, Forms 3 and 4 do require such specific allegations. Sizemore, General Scope and Philosophy of the New Rules, 5 Wake Forest Intramural Law Review 1.
[7, 8] Under the new Rules the trial must proceed within the issues raised by the broad pleadings unless the pleadings are amended. The new Rules achieve their purpose of insuring a speedy trial on the merits of a case by providing for and encouraging liberal amendments to conform pleadings and evidence under Rule 15(a), by pretrial order under Rule 16, during and after reception of evidence under Rule 15(b), and after entry of judgment under Rules 15(b), 59 and 60. Such amendments are made upon motion and with leave of court, by express consent, and by implied consent.
In instant case, since plaintiff failed to amend by leave of court or pretrial order and there was no amendment by express consent, we need only consider whether the pleadings were amended by implied consent.
The doctrine of implied consent is based upon the provisions of Rule 15(b), which we quote:
(b) Amendments to conform to the evidence. — When issues not raised by the pleadings are tried by the express or implied consent of the parties, they shall be treated in all respects as if they had been raised in the pleadings. Such amendment of the pleadings as may be necessary to cause them to conform to the evidence and to raise these issues may be made upon motion of any party at any time, either before or after judgment, but failure so to amend does not affect the result of the trial of these issues. If evidence is objected to at the trial on the ground that it is not within *57the issues raised by the pleadings, the court may allow the pleadings to be amended and shall do so freely when the presentation of the merits of the action will be served thereby and the objecting party fails to satisfy the court that the admission of such evidence would prejudice him in maintaining his action or defense upon the merits. The court may grant a continuance to enable the objecting party to meet such evidence.
Dean Dickson Phillips of the University of North Carolina Law School, in McIntosh, N. C. Practice and Procedure, Vol. 1, Supp. 1970, § 970.80, considered Rule 15(b) as it affects conforming amendments to pleadings after offer of evidence. He there, in part, stated:
The most significant feature of Rule 15’s approach to amendments to conform pleadings to proof already adduced is its abandonment, both in name and practice, of the highly technical code doctrine of “variance.” Instead, Rule 15 (b) approaches the problem from a completely functional standpoint. Two situations involving proof outside the scope of the pleadings are posited. In the first, no objection is made upon the introduction of evidence that it is outside the pleadings. In this situation, the Rule provides that “when issues not raised by the pleadings are tried by express or implied consent of the parties, they shall be treated in all respects as if they had been raised in the pleadings.” This is the doctrine of “litigation by consent When this occurs, an actual conforming amendment may be made on motion either before or after judgment, but it is not essential — the pleadings are by the Ride deemed amended. A party who fails to object to evidence is of course initially presumed to have given “implied consent” by silence. He can avoid the effect only by satisfying the court that under the circumstances, his consent to having certain issues considered by the trier of fact should not be implied from his failure to object to particular evidence.” (Emphasis ours.)
In the case of Securities and Exchange Commission v. Rapp, (2d Cir., 1962), 304 F. 2d 786, the United States Court of Appeals considered their similar Rule 15(b) and, inter alia, stated:
*58In the district court Judge Murphy gave judgment for defendants dismissing the complaint. The principal ground of decision appears to have been that the pleadings did not conform to the proof; he denied a motion, made at the close of argument, to amend the pleadings so to conform. This ruling was clearly in error. F. R. 15 (b) provides that “[w]hen issues not raised by the pleadings are tried by express or implied consent of the parties, they shall be treated in all respects as if they had been raised in the pleadings.” This is mandatory, not merely permissive. The rule then provides for free or delayed amendment, but states that “failure so to amend does not affect the result of the trial of these issues.” Indeed, formal amendment is needed only when evidence is objected to at trial as not within the scope of the pleadings. . . . (Emphasis ours.)
Accord: Tillman v. National City Bank of New York, (2d Cir., 1941), 118 F. 2d 631; Joyce v. L. P. Stewart, Inc., (D.C. Cir., 1955), 227 F. 2d 407; Gallon v. Lloyd-Thomas Co., (8th Cir., 1959), 264 F. 2d 821. See also 3 Moore’s Federal Practice, 2d Ed., § 15.13(2), and cases there cited.
 The thrust of this rule seems to destroy the former strict code doctrine of variance by allowing issues to be raised by liberal amendments to pleadings and, in some cases, by the evidence. Under 15(b) the rule of “litigation by consent” is applied when no objection is made on the specific ground that the evidence offered is not within the issues raised by the pleadings. In such case the statutory rule, in effect, amends the pleadings to conform to the evidence and allows any issue raised by the evidence to go to the jury. Even when the evidence is objected to on the ground that it is not within the issues raised by the pleadings, the court will freely allow amendments to present the merits of the case when the objecting party fails to satisfy the court that he would be prejudiced in the trial on its merits. The far-reaching effect of this statutory rule is emphasized by the burden placed on the objecting party to specify the grounds of objection and to satisfy the court that he will be prejudiced by the admission of the evidence or by litigation of the issues raised by the evidence. The objecting party must meet these requirements in order to avoid “litigation by consent” or allowance of motion to amend.
*59  Further, it is apparent that the effect of this rule is to allow amendment by implied consent to change the legal theory of the cause of action so long as the opposing party has not been prejudiced in presenting his case, i.e., where he had a fair opportunity to defend his case. In this connection, we feel compelled to note that the better practice dictates that even where pleadings are deemed amended under the theory of “litigation by consent,” the party receiving the benefit of the rule should move for leave of court to amend, so that the pleadings will actually reflect the theory of recovery.
In instant case defendants’ counsel did not object to Shu-mate’s alleged statement on the ground that it was outside the pleadings. The record reveals- that the legal effect of the evidence was argued by counsel for defendants without any mention of the broadened issue raised by the evidence or without any contention that defendants were unprepared to litigate the broadened issue because of unfair surprise. Defendants offered no evidence tending to satisfy the court that they would be unduly prejudiced by the admission of the alleged statement and the issue thereby raised.
 Thus the statement allegedly made by defendant Shumate, in effect amended the pleadings to conform to the evidence and broadened the issue of negligence so that the jury could consider whether defendants breached a duty owed to plaintiff by furnishing a golf cart which they knew had no brakes on it when going backwards.
Further, plaintiff’s allegations that defendants failed to warn of defective brakes and that defendants failed to instruct as to the proper use of the cart on steep terrain and the proper use of the brakes on the golf cart, at least negated any inference of unfair surprise as to the evidence of complete absence of brakes when the cart was rolling backward.
 If it be a breach of duty for a bailor for hire to fail to warn of a known defect in the brakes of the bailed vehicle, it certainly follows that it would be a breach of duty for him to fail to warn that the bailed vehicle had “no brakes on them going backwards.”
Plaintiff’s complaint alleged:
4. That the plaintiff is informed and believes that the defendant, Tanglewood Park and the defendant, Grady *60Shumate, who is pro, agent, servant and employee of Tanglewood Park, share in the rental income of the use of said golf carts. That the plaintiff is further informed that the said golf carts are owned and maintained by Tanglewood Park under the direct supervision of the defendant, Grady Shumate, its agent, servant and employee.
The answer of defendants to Paragraph 4 is as follows:
Denied, except it is admitted that defendant Park and defendant Shumate share in rental fees on golf carts; that said golf carts are owned and maintained by defendant Park and that the maintenance of said carts is under the supervision of defendant Shumate; and that on May 3, 1967, and for some time prior to that date, defendant Shumate was an employee of the defendant Park and was a professional golfer.
 The allegations in the complaint and the admissions in the answer established the relationship of principal and agent between defendant Shumate and the corporate defendant at the times plaintiff complained of. A principal is chargeable with and bound by the knowledge of or notice to his agent, received while the agent is acting as such within the scope of his authority and in reference to which his authority extends. Norburn v. Mackie, 262 N.C. 16, 136 S.E. 2d 279. Thus the corporate defendant was charged with and bound by its agent’s knowledge that the golf cart had no brakes when rolling backward.
We conclude that the evidence offered by plaintiff, when considered in the light most favorable to the plaintiff, was sufficient to have a jury pass on it.
The decision of the Court of Appeals is
