Description

Description: [Industrial field of use] The present invention relates to a motorcycle having a storage compartment provided below a seat.

[Prior Art] In a motorcycle, a seat rail extending rearward is connected to a rear portion of a main frame portion that supports an engine, and a seat on which a driver or a passenger sits is mounted on the seat rail. is set up. A rear fender that covers the rear wheel from above is inserted under the seat, and a space portion formed between the rear fender and the seat is used for accommodating small articles such as on-vehicle tools and maps. A storage box is arranged.

[Problems to be Solved by the Invention] However, in the conventional motorcycle, since the bottom surface of the seat is in contact with or close to the seat rail, the space between the rear fender is extremely narrow. For this reason, even if the storage box is installed between the rear fender and the seat, the storage box itself becomes flat, and there is a problem that the capacity cannot be sufficiently secured.

The present invention has been made based on such a situation, and it is possible to secure a wide space for installing a storage case between the seat and the rear fender without sacrificing seating comfort, and to provide a sufficient storage capacity. In addition to being able to secure the space, the frame structure can be simplified by using the storage case as a bracket to hold the rear fender and various types of lighting equipment, and moreover, the rear fender and lighting equipment can be accurately placed at regular positions. The purpose is to provide motorcycles.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a frame member that extends in the front-rear direction passing above a rear wheel, and a front portion on which a driver sits is provided above the frame member. And a rear seat on which a passenger is seated are arranged side by side, and a rear fender made of synthetic resin that covers the rear wheel from above is arranged below the rear part of this seat. I am trying.

And, while covering the rear fender and the frame member with a side cover continuous from the side to the seat,
The bottom surface of the rear portion of the seat is provided at a position higher than the bottom surface of the front portion, and a box-shaped synthetic resin case is placed in the space between the bottom surface of the rear portion of the seat and the rear fender. The storage case is attached to the frame member, the rear fender and the lighting device are attached to the storage case, and at least the bottom wall of the storage case is integrally provided with a reinforcing rib.

[Operation] With this configuration, since the bottom surface of the rear portion of the seat on the frame member is located higher than the bottom surface of the front portion, the bottom surface of the rear portion is separated from the upper surface of the rear fender, and A wide space can be secured between them. Therefore, the vertical dimension of the container can be increased, and the capacity of the container can be sufficiently secured.

Also, the rear part of the seat is thinned by raising the position of its bottom surface, but this rear part is used much less frequently than the front part where the driver is seated, so the rear part Even if the thickness of the vehicle is reduced, the driver does not have any problem in sitting on the seat. Moreover, the frame members only need to be provided with brackets for attaching a single container, and no special brackets for attaching the rear fender or the lighting device are required.
Therefore, the frame structure can be simplified, and the weight and cost can be reduced.

In this case, since the storage case is reinforced by ribs and the rigidity is increased, even if this storage case is used as a bracket, the storage case will not be deformed, and the rear fender and the lighting equipment will be in the regular positions. Can be placed accurately.
