Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a motorcycle with a roof provided with a storage box at a rear part of a vehicle body.

[Conventional technology]

In recent years, there has been a demand for motorcycles to have a roof for protecting occupants from rain and wind, and one that responds to this is disclosed, for example, in Japanese Patent Application Laid-Open No. Sho 59-77984. This means that a front windshield is detachably provided in front of the seat of a generally configured vehicle body, a rear panel is detachably provided behind the seat, and the roof is detachably mounted over the upper part of the front windshield and the upper part of the rear panel. It is configured to protect the occupant from rain and wind by providing it.

[Problems to be solved by the invention]

However, in such a structure, by providing a roof that covers the upper part of the seat provided at a general height, the vehicle height increases, and it becomes difficult to improve running stability. That is, the area that the traveling wind hits increases,
This is because the influence of the traveling wind on the vehicle body increases. Further, in this type of vehicle, it is required to store a relatively large object without being exposed to rain and wind for convenience in use. The present invention has been made in view of such circumstances, and provides a motorcycle with a roof that can improve usability while suppressing deterioration in running stability.

[Means for solving the problem]

The motorcycle with a roof according to the present invention includes a unit swing type engine in which a low-floor footrest is arranged between a steering handle and a seat, and a rear wheel is supported at a rear portion below the seat. In a motorcycle in which a front portion is pivotally attached to a body frame and a shock absorber is interposed between the rear portion and the body frame, the motorcycle is disposed so as to be able to swing up and down.
It comprises a seat portion extending substantially horizontally and a backrest portion rising obliquely upward and rearward from the rear end of the seat portion, and is rotatable around the front end, and the upper end of the shock absorber is provided behind the seat portion of the seat. Arranged, a substantially gate-shaped support frame that stands upward is provided behind the seat portion and above the rear wheel and at the rear of the body frame, and inward of the support frame, diagonally upward and forward. Opening this opening to form a storage space that can be opened and closed by the seat back, providing a roof that covers the footrest and the seat, and the front end of the roof is detachably fixed near the upper edge of the handlebar of the vehicle body. The lower ends of a pair of left and right stays supporting the rear part of the roof are detachably fixed to the upper part of the support frame, the stay is inclined obliquely forward and upward, and the rear end of the roof extends rearward from the stay. It is a thing.

[Action]

In the present invention, by arranging the upper end of the shock absorber behind the seat sitting portion, the seat seating portion can be lowered while sufficiently securing the stroke of the shock absorber, and the area where the traveling wind hits by lowering the roof is reduced. can do. Further, by utilizing the space inside the seat back portion and the support frame of the roof, a large storage space can be formed by suppressing the seat seating portion to be low and suppressing the vehicle body from increasing in the front-rear direction.

Furthermore, by adopting a structure that provides a pair of left and right stays that support the rear part of the roof and inclines diagonally forward and upward, the roof can be supported in a short span in the front and rear direction, so that the roof hit by the traveling wind is surely Become supported. Since the stays are provided so as to be paired on the left and right, the rear view is not obstructed by the stays.

Furthermore, since the front end of the roof is detachably fixed near the upper edge of the handlebar of the vehicle body, and the rear part is detachably fixed to the support frame via stays, the overall size of the roof structure should be small. Can be easily removed when the roof is not required.
