Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of Invention] The present invention relates to a rear structure of a motorcycle body.

[Conventional technical background and problems] Generally, in a large-sized motorcycle, a passenger seat is provided behind the driver's seat to allow two-seaters. A grab bar is provided on the rear side of the passenger seat so that the passenger can hold the grab bar and support the body.

By the way, side covers are provided on both lower outside portions of the driver seat and the passenger seat, and the left and right side covers are integrally connected at their rear end portions by tail covers. However, in the case where the both side covers and the tail cover are integrally formed as described above, the shape is complicated, so that the productivity is poor, and the degree of freedom of the shape is low due to the structural restrictions of the molding die. There is a problem such as.

[Object of the Invention] In view of such a point, the present invention can divide the both side covers and the tail cover, increase the degree of freedom of shape and improve productivity, and reduce the time required for assembly. Moreover, it is an object of the present invention to obtain a motorcycle rear body structure capable of preventing an increase in the number of parts.

[Configuration of the Invention] Hereinafter, an embodiment of the invention will be described with reference to the accompanying drawings.

On the left and right rear frames 2 of the vehicle body 1, front bridge pieces 3,
Three bridge pieces, a middle bridge piece 4 and a rear bridge piece 5, are welded. Then, side covers are fastened to both outer sides of the rear frame 2.

The tail cover 7 formed so as to cover the rear bridge piece 5 is on a line that substantially coincides with the extension line of the outer edge (shown by the dotted line in the figure) of the seat mounted on the rear frame 2 as described later. The left and right side covers 6 are thus divided. A locking hook 8 is provided on the inner surface of the side wall of the tail cover 7 so as to project downward from the inner surface of the side wall. The locking hook 8 is substantially horizontal at the step of the upper edge of the side cover 6 facing the inside of the vehicle body. The tail cover 7 and the side cover 6 are connected to each other by being inserted and engaged in a locking hole 9 which is long in the front-rear direction and which is formed in the portion. Then, in the state where the engaging hook and the locking hole are locked, the tail cover 7
The outer surface of the side cover 6 and the outer upper surface of the side cover 6 are substantially flush with each other.

Both ends of the grab bar 10 are brought into contact with the side surface of the tail cover 7 arranged so as to cover the rear bridge piece 5 so as to match the holes provided in the side surface, and both ends of the grab bar 10 are attached to the rear bridge piece 5. It is fastened.

On the other hand, in the passenger seat 11, the rear projection 12 is inserted into the front hole 13 of the bridge piece 5, and the front end is overlaid on the middle bridge piece 4 and fastened with a bolt. In addition, the driver seat
The front projection 15 of the reference numeral 14 is locked by inserting the front projection 15 into the front bridge piece 3 and inserting the rear portion into a key lock 16 attached to the middle bridge 4.

FIG. 3 is a view showing a state where the long table cover 17 is used. After removing the grab bar 10, the tail cover 7 and the passenger seat 11, the hook 18 at the lower rear portion of the long tail cover 17 is attached to the side cover 6. It is attached to the rear frame 2 by being hooked in the locking hole 9, the front end being overlaid on the middle bridge piece 4 and tightened with bolts. A waist support cushion 19 is provided on the front upper portion of the long tail cover 17.

Then, by removing the key lock 16 and the driver seat 14, the tail cover 7, the grab bar 10, and the passenger seat 11 can be easily attached and detached.

[Effect of device]

As described above, according to the present invention, the pair of left and right side covers mounted on the left and right rear portions of the vehicle body and the tail cover that connects the side covers to each other from above from the upper portion of the vehicle body are generally referred to as rear extension lines of the outer edge of the seat. The upper and lower parts of the side cover are divided into upper and lower parts on a line that coincides with each other, and a substantially horizontal surface portion extending inward of the vehicle body is formed at the upper edge of the side cover. A locking hook protruding downward from a side wall inner surface of the tail cover at a position corresponding to the locking hole is formed, and both side covers and the tail cover are connected by engagement of the locking hole and the locking hook. In addition, since the outer surface of the tail cover and the outer surface of the side cover are substantially flush with each other in the locked state, the side cover and the tail cover can be manufactured separately, and With the shape is simplified to improve the productivity, reduce the mold structural constraints, increases the degree of freedom in shape, it is possible to improve the appearance. Further, since the three members of the both side covers and the tail cover are connected by engagement, the rigidity is improved, it is not necessary to use bolts or screws, and moreover, the tail cover is provided on the substantially horizontal surface portion of the upper edge of the side cover. By disposing the lower end edge of the plate back and forth, the locking hook can be easily inserted and engaged in the locking hole, the time required for assembly can be reduced, and an increase in the number of parts can be prevented.
