Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a motorcycle having a helmet storage chamber provided below the seat.

(Prior Art) Conventionally, a motorcycle equipped with a helmet storage chamber having a bottom portion close to a power transmission case between a rear wheel and an engine is known (for example, Japanese Utility Model Application Publication No. 59-26089).

(Problem to be Solved by the Invention) In such conventional motorcycles, when increasing the diameter of the rear wheel, the rear wheel shaft must be moved rearward to avoid interference between the storage chamber and the rear wheel. Alternatively, the entire storage chamber must be raised upward, or even only the bottom of the storage chamber must be raised upward. Moving the rear axle backwards lengthens the wheelbase. Further, when the entire storage chamber is raised upward, the seat is located on the upper surface of the storage chamber, so that the height of the seat above the ground becomes higher. Furthermore, if only the bottom of the storage chamber is raised upwards, the volume of the storage chamber decreases, making it impossible to store the helmet.

The present invention has been made in view of the above circumstances, and it is possible to avoid the problem of increasing the wheelbase, height of the seat, or making it difficult to store the helmet in the storage compartment. An object of the present invention is to provide a motorcycle in which the diameter of the motorcycle can be increased.

(Means for Solving the Problems) In order to achieve the above object, the motorcycle of the present invention has a helmet storage chamber provided below the seat. A bottom plate is provided at an angle, a recessed part is provided in the inclined part of the bottom plate to protrude into the storage chamber to avoid interference with the rear wheel, and a support part is provided in which the lower opening of the helmet is located in the projected part, It is provided at the front part of the bottom plate.

(Function) The recess provided in the slope of the bottom plate of the storage chamber prevents interference between the bottom plate of the storage chamber and the rear wheel.

Furthermore, the lower opening side of the helmet is located on the protruding part that corresponds to the recess and projects inward of the storage chamber due to the support section provided in the front part of the bottom plate of the storage chamber, so that there is no problem in storing the helmet.
