(A position corresponding to), a concave portion is formed which is depressed toward the inside of the helmet, and the top of the engine and the vicinity of the spark plug can enter into the concave portion. It is desirable that a window that can be opened and closed be provided inside the storage box, and that the ignition plug be attached and detached by opening this window.

(Effects of the Invention) As described above, the present invention arranges the driving seat almost directly above the engine, and arranges the storage box between the left and right footrests and forward of the front edge of the driving seat. Since the cover plate is provided separately from the driving seat and is provided so as to be smoothly inclined forward and downward from the upper edge of the front of the driving seat having substantially the same height as the seating surface of the driving seat, the driving seat and the storage box are provided. The position can be lowered, so that the center of gravity of the vehicle can be lowered. In addition, since the cover plate has a vertical cross-sectional shape in the width direction that is convex upward, the opening edge of the storage box can be lowered to make the opening large, and luggage can be easily taken in and out. In addition, since this lid plate is inclined forward and downward, and the cross section in the vehicle width direction is convex in a substantially arc shape, it is difficult for the foot to hit when getting on and off, and when getting on, the foot follows the curved surface of this lid plate. It can be extended. Further, the storage box can be vertically expanded to the height of the seating surface of the operation seat, and the lid plate has a vertical cross-sectional shape projecting upward, so that the capacity of the storage box can be greatly increased. As described above, the capacity of the storage box can be sufficiently increased while the driving seat is lowered so that a comfortable riding posture can be obtained.

In addition, the lid plate is separate from the driving seat and the upper part can be opened and closed upward and forward with the front lower part as the center, so it is easy to open and close only the storage box regardless of the opening and closing of the driving seat. It makes it easy to take in and out especially large helmets. Therefore, it is also possible to open and close the lid plate while the driver's seat is seated for loading and unloading luggage.
