Furthermore, in the above embodiment, the frame body 4
Since the fuel tank 20 and air cleaner 19 are arranged below the seat 22, there is no need to change the parts layout, and it is sufficient to change the leg shield 36 and main tube 3, so there is no increase in cost.

Furthermore, since the semi-jet type helmet 45 can be placed in the front storage chamber 41 with the top A facing backward, the front lid 42 can be configured in a semicircular shape. Therefore, the front storage chamber 41 and the front lid 42 can be designed so that they do not feel wide, and since there are no corners, safety is also high.

Moreover, since the brim D of the semi-jet type helmet 45 can be placed upward, the front storage compartment 41
Also, the dimension of the front lid 42 in the vehicle longitudinal direction can be shortened. As a result, a good space for the foot passage between the upper part of the leg shield 36 and the seat 22 can be ensured.
