Straddle type vehicle

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a straddle type vehicle, and more particularly to a configuration of a side cover that can improve the comfort of a passenger's foot.

Conventionally, it is known that a side cover is provided on the left and right sides of the vehicle under the seat for two persons, and a space between them is used as a straddle type vehicle of the storage space. For example, it is proposed in the "body cover structure of a quick-acting type vehicle" (Patent Document 1) of the Japanese Patent Publication No. 2002-173069. In the first and twelfth drawings of the above publication, a straddle-type vehicle is disclosed in the side of the rear cover 13 (the same as the one shown in the above-mentioned publication, the same applies hereinafter), below the front seat 14a and before the rear seat 14b. The flat portion 18 is provided at the position to ensure the comfort of the feet of the same passenger.

Patent Document 1: Japanese Patent Laid-Open Publication No. 2002-173069

However, in the configuration as described above, a plane portion in which a vicinity portion including the ridge line is cut off is provided at a position overlapping the foot of the same passenger in a side view, wherein the ridge line is formed by the lower surface of the side cover and the upper portion The largest side protrusion is assumed by the inclined surface, so that the frame located inside the side cover must be disposed inside the side avoiding the removed portion, and as a result, the interval between the frames on the left and right sides becomes smaller, and When the storage box is installed between the frames, it is possible to compress the size of the storage box in the vehicle width direction.

On the other hand, the speed of the Scooter type vehicle is from the heat generated by the engine. The square rises and is easy to accumulate under the seat between the side covers on the left and right sides. In particular, when a storage box is provided between the side covers, the passage between the side cover and the storage box from which the heat of the engine rises is restricted. As a countermeasure against this, it is conceivable that the side cover forms a ridge line that protrudes the side cover toward the side and extends rearward from the front portion thereof. The hot air rising from the engine can flow in the inner space of the ridge line extending rearward from the front side of the side cover, and diverge from the top of the engine toward the rear of the vehicle, thereby promoting the divergence of heat generated from the engine. However, in the configuration of Patent Document 1, the provision of the flat portion by cutting off one of the ridge lines causes the divergence of heat obtained by forming the ridge line to be hindered.

Moreover, when the foot of the same passenger is placed on the footrest of the same passenger, there is also a situation in which the lower side of the side cover is protruded by the inside of the joint of the ankle, and the comfort of the foot is damaged. However, there has not been a straddle-type vehicle that takes into consideration the comfort of the occupants.

The present invention has been made in view of such circumstances, and an object thereof is to provide a straddle-type vehicle that can improve the comfort of a passenger's foot and at the same time realize the divergence of heat generated from the engine and the securing of the storage space.
