84 is a lid plate of the storage box 70. This cover plate 84 covers the storage box 70 from above and slopes smoothly forward and downward from the front edge of the driver's seat 76. The longitudinal cross-sectional shape in the width direction of the vehicle body is convex upward in a substantially circular arc shape. That is, by passing the opening edge 70c of the storage box 70 forward and backward through the side of the helmet 72, a large opening of the storage box 70 is ensured, while the left and right edges of the lid plate 84 are extended to the opening edge 70c. As a result, when the rear portion of the cover plate 84 is opened upward, the opening of the storage box 70 can be enlarged, making it easier to take the helmet 72 in and out.

Here, since the cover plate 84 is convex upward in a substantially arc shape, it substantially follows the shape of the helmet, making it suitable for storing the helmet. The front edge of the lid plate 84 is connected by a link type hinge 85, and when the lid plate 84 is opened, the entire lid plate 84 moves upward to prevent interference with the leg shield 66. Further, a key 86 is fixed to the rear edge of the cover plate 84.

In this embodiment, the engine 52 of the moving crab knit 50 stands upward, but the engine 52 may be tilted forward substantially horizontally. In this case, a recess that recesses toward the inside of the helmet is formed on the rear surface of the storage box (a position corresponding to 70b in FIG. 1), and the top of the engine and the vicinity of the spark plug can be inserted into this recess. It is desirable to provide a window inside the storage box that can be opened and closed, and to open the window to attach and detach the ignition plug.

(Effects of the Invention) As described above, the present invention provides a storage box that is arranged between the left and right footrests, and is provided so as to be sloped smoothly forward and downward from the front edge of the driver's seat, which is a cover plate that covers the storage box. Because of this, the position of the driver's seat and the storage box can be lowered, thereby lowering the center of gravity of the vehicle. In addition, since the vertical cross-sectional shape of the lid plate in the width direction is convex upward, the opening edge of the storage box can be lowered to enlarge the opening, making it easier to take items in and out. Furthermore, since this cover plate is inclined downward and has a convex cross section in the width direction of the car body, it is convex in the shape of an approximately circular arc. You can also extend it.
