Description

  The present invention relates to a rear structure of a motorcycle.

As a conventional rear structure of a motorcycle, there is known a structure in which a rear cover that covers both sides and a rear part under a seat and a rear fender that covers an upper part of a rear wheel so as to be connected to the rear cover are provided at a rear part of a vehicle body ( For example, see Patent Document 1.)
Japanese Patent No. 4052871

  According to FIGS. 1 and 3 of Patent Document 1, a rear cover 23 is attached to the rear portion of the body frame 10 so as to extend rearward and obliquely upward, and the rear fender projects so as to protrude rearward and obliquely downward from the rear end portion of the rear cover 23. 24 is provided, and a taillight 37 located above the rear fender 24 is provided in an opening formed in the rear end portion of the rear cover 23.

  In a side view, the rear cover 23 is formed slim so that the width gradually decreases as it goes diagonally upward to the rear, and the rear fender 24 is formed so that the width gradually decreases as it goes diagonally downward to the rear, the rear cover 23 and the rear fender 24. However, in order to further improve the merchantability, it is desired to increase the degree of freedom in designing the rear part of the vehicle body while maintaining visual unity.

Further, since the rear fender 24 protrudes greatly from the rear cover 23 side and the license plate 40 is attached to the front end portion side of the rear fender 24, the rigidity for preventing bending and preventing vibration is increased as much as possible. It is expected to secure while holding down.
An object of the present invention is to provide a rear structure of a motorcycle capable of ensuring the rigidity of a rear fender while increasing the degree of freedom in design and providing a new appearance.

  According to the first aspect of the present invention, in a motorcycle in which a rear fender is disposed below the pair of left and right side covers that cover the vehicle body, the side cover covers at least the vehicle body rear portion, and the left and right sides are coupled at the rear end portion. A protrusion is attached to the side cover, and a protrusion is formed on a part of the rear part of the rear fender so as to expose the upper and lower surfaces, and the periphery of the protrusion is covered with the rear end of the side cover.

  As a function, the rear part of the rear fender is formed with a protruding part that partially exposes the upper and lower surfaces, so that the rear end part of the side cover is inserted below the lower surface of the protruding part of the rear fender. It can be formed so as to surround the base portion, the degree of freedom of the shape of the side cover is increased, and the appearance is improved.

  In addition, since the periphery of the protruding portion of the rear fender is covered with the side cover, an impression that the protruding portion protrudes from the side cover is given, and the rear fender and the side cover can be seen integrally. On the other hand, the protrusion and the lower end of the rear fender are a single member, but can provide the same visual effect as that of another component.

  Further, since the rear fender and the side cover overlap each other around the protruding portion, it contributes to improvement of rigidity and a predetermined rigidity of the rear fender is ensured.

The invention according to claim 2 is characterized in that a separate rear cover is provided above the side cover and the rear fender.
As an action, for example, even when the vehicle body space such as a storage space is increased at the rear part of the motorcycle or when the rear part of the side cover extends below the protruding part, by providing a separate rear cover, An increase in the area of the side cover is suppressed, and a light appearance can be maintained.

The invention according to claim 3 is characterized in that the projecting portion is a mounting portion of the license plate.
As an operation, since the protruding portion is integrally formed on a part of the rear portion of the rear fender, for example, an increase in the number of components can be suppressed as compared with the case where the mounting portion of the license plate is provided separately on the rear fender. Also, a new rear body shape with a side cover extending inward of the license plate is possible.

In the invention according to claim 1, the side cover covers at least the rear part of the vehicle body, the left and right sides are coupled at the rear end part, the rear fender is attached to the side cover, and the upper and lower surfaces thereof are exposed at a part of the rear part of the rear fender. Since the protruding portion is formed and the periphery of the protruding portion is covered with the rear end portion of the side cover, the degree of freedom of the shape of the side cover can be increased and the appearance can be improved. On the other hand, the projecting portion and the lower end portion of the rear fender are a single member, but can provide the same visual effect as another component.
Moreover, the impression that a protrusion part protrudes from a side cover can be given, and a design with a sense of unity can be made for a rear fender and a side cover.

  Furthermore, the rear fender and the side cover overlap each other to ensure the rigidity of the rear fender, and it is necessary to increase the plate thickness of the rear fender, to provide ribs on the rear fender, and to form the rear fender in a complicated shape. Therefore, it is possible to suppress the bending and vibration of the rear fender.

  In the invention according to claim 2, since a separate rear cover is provided above the side cover and the rear fender, the rear vehicle body space is increased or the rear portion of the side cover is extended below the protruding portion. However, by providing a separate rear cover, an increase in the area of the side cover can be suppressed, and a light appearance can be maintained.

  In the invention according to claim 3, since the projecting portion is the license plate mounting portion, the number of parts can be reduced and the cost can be reduced as compared with the case where the license plate mounting portion is provided separately on the rear fender. Can do. Moreover, it can be set as the new vehicle body rear part shape which extended the side cover inside the license plate.
