Description

  The present invention relates to a grip structure for a motorcycle, and more particularly, to a grip structure provided on a rear body frame of a motorcycle.

  As an example of a grip structure of a motorcycle, a rear body cover and a rear fender are provided to cover the periphery of the rear body frame. It is known that this projecting portion forms a grip (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 08-40339 (2nd page, FIG. 3)

  By the way, in the grip structure of the motorcycle described in Patent Document 1, the rear body cover has a bulge on the side of the vehicle, and the grip is disposed vertically below the rear body frame. Since the grip overlaps, the distance in the vehicle width direction from the outer surface of the rear body cover to the grip becomes long, and it is difficult for the user to apply force when gripping the grip. Further, since the grip is disposed in the vicinity of the rear fender, dust such as mud adheres to the inside of the grip, and there is a possibility that the user's hand holding the grip may become dirty. Further, since the joint portion between the rear vehicle body cover and the rear fender is disposed on the side surface of the vehicle body, there is a problem that the appearance of the motorcycle is deteriorated.

  The present invention has been made in order to eliminate such inconveniences, and an object of the present invention is to allow a user to securely grip a grip and prevent dust such as mud from adhering to the grip. An object of the present invention is to provide a grip structure for a motorcycle that can improve the appearance of the motorcycle.

In order to achieve the above-described object, the invention according to claim 1 is attached to a rear body frame, a grip provided on the rear body frame, a rear body cover covering at least the rear body frame, and the rear body frame. A grip structure for a motorcycle including a rear fender that covers an upper part of the wheel, and the grip extends from the rear body frame outward in the vehicle width direction so as to be substantially U- shaped in a plan view. A grip cover provided on the rear fender and covering the lower and inner sides of the grip body . The grip body is formed of a pipe-shaped member having a circular cross section, and both ends thereof are joined to the rear body frame, and from the rear body frame. Opened upward in a side view, formed by a vertically extending portion extending downward and a front and rear portion connecting the front and rear vertically extending portions in the vehicle longitudinal direction. Has a substantially C-shaped portion which, in the handle cover is formed grip recesses entering from below to above inside approximately U-shaped portion of the grip body, recesses for gripping the vehicle width direction than the rear body frame It is outside and located inward in the vehicle width direction from the front and rear parts of the grip body, and the upper end of the grip recess is located above the front and rear parts. A notch corresponding to the shape is formed .

  In the invention according to claim 2, in addition to the structure of the invention according to claim 1, the grip cover is formed with a thickness along the grip body, and a grip contact portion that contacts the grip body is formed. It is characterized by that.

  According to a third aspect of the present invention, in addition to the configuration of the first or second aspect of the invention, the rear fender is formed with a rear wheel recess for housing the rear wheel, and the grip cover is provided with a rear wheel recess. A convex portion projecting downward is formed between the grip and the concave portion for grip.

Invention of claim 4, in addition to configuration of the invention according to claim 1 to 3, the lower end of the rear body cover is bent in the vehicle width direction inner side, rear body cover and the rear fender and a grip A junction with the cover is disposed below the vehicle body.

According to the grip structure for a motorcycle according to claim 1, the grip is provided on the rear fender and the grip body extending outward in the vehicle width direction from the rear body frame so as to be substantially U- shaped in plan view. A grip cover that covers the lower and inner sides of the grip body, and the grip cover is formed with a grip recess that enters the grip body from the lower side to the upper side. Therefore, the distance in the vehicle width direction from the outer surface of the rear body cover to the grip is shortened, and the user can securely grip the grip. Further, since the grip is disposed away from the rear wheel, it is possible to prevent dust such as mud from adhering to the grip. Further, since the grip body is covered with the grip cover, the appearance of the motorcycle can be improved. Further, since the grip recess is formed in the grip cover, the user can easily grip the grip, and the handling of the motorcycle can be improved. In addition, since the rear body cover is formed with a notch corresponding to the side surface shape of the grip cover, it does not affect the side surface shape of the rear body cover, so that the appearance of the motorcycle is not deteriorated. The grip can be located away from the rear body frame.

  According to the grip structure for a motorcycle according to claim 2, since the grip cover is formed with a thickness along the grip body and a grip contact portion that contacts the grip body is formed, the grip body and the grip Since the contact portion with the cover increases, the strength of the grip cover can be improved.

  According to the grip structure for a motorcycle according to claim 3, the rear fender is formed with a rear wheel recess for housing the rear wheel, and the grip cover is disposed between the rear wheel recess and the grip recess. Since the projections projecting from the rear wheels are formed, dust such as mud scattered from the rear wheel is received by the projections, so that dust such as mud can be reliably prevented from adhering to the grip.

According to the grip structure for a motorcycle according to claim 4 , the lower end portion of the rear body cover is bent inward in the vehicle width direction, and the joint portion between the rear body cover, the rear fender, and the grip cover is disposed below the vehicle body. Therefore, since the joint portion is not exposed to the outside, the grip can be disposed at a position away from the rear body frame without deteriorating the appearance of the motorcycle.
