(2) Prior Art Conventionally, in motorcycles that have an article storage section in the body frame, the article storage box is connected to the steering mechanism at the front end of the vehicle body and the seat so that the rider can handle and operate articles while sitting on the seat. It is conventionally known that an article storage box is disposed between the storage box and the upper surface thereof has an entrance that can be opened and closed by a lid (for example, see Japanese Utility Model Publication No. 1988-19248).

(3) Problems to be solved by the invention However, in the above-mentioned conventionally known method, since a fuel tank is interposed between the article storage box and the seat,
Therefore, the effective capacity of the goods storage box becomes smaller, and the effective capacity of the fuel tank cannot be increased significantly.
Furthermore, there are problems such as the relatively heavy fuel tank being placed at a high position. In this conventionally known system, since the power unit is located below the article storage box, it is virtually impossible to arrange the fuel tank below the article storage box in order to avoid the above-mentioned problem.

The present invention has been proposed in view of the above, and it is possible to solve the above-mentioned problems of the conventional system by allowing the fuel tank to be placed below the goods storage box without being obstructed by the power unit. An object of the present invention is to provide a motorcycle which can effectively prevent spilled fuel from entering an article storage box when fuel is injected into the motorcycle.
