Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention This application relates to a vehicle body structure and, more particularly, to a vehicle body structure having an improved exterior appearance.

[0002]

2. Description of the Related Art Japanese Utility Model Publication No. 5-39038 discloses that a storage compartment having an opening opened upward by a seat and a fuel tank arranged behind the storage compartment are supported on a rear portion of a vehicle body frame. There is shown a scooter type vehicle in which a fuel tank and a storage case are covered with a vehicle body cover, and a carrier for supporting luggage is mounted on an upper surface portion of the vehicle body cover behind the seat.

[0003]

By the way, when the carrier is provided on the vehicle body cover as in the above-mentioned conventional example, the carrier is exposed, so that a difficult design is required to improve the appearance. On the other hand, if the carrier is omitted,
There is an inconvenience that the body cover is deformed by directly putting the luggage on the body cover. Then, this application aims at solving such a problem.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention has a storage compartment in which an opening opened upward is opened and closed by a seat, and a fuel tank arranged behind the storage case. In a vehicle of a type that is supported above and covers the periphery of the fuel tank and the storage case with a vehicle body cover, at least an upper side of the fuel tank is surrounded and an inner stay extending in the front-rear direction along the inside of the upper surface of the vehicle body cover behind the seat. Is provided. At this time,
The inner stay extends to the rear of the fuel tank and extends downward.
A downwardly extending portion for
By attaching the front end of the protrusion to the rear end of the body frame,
Wear. Also, an optional part that allows luggage to be placed on the inner stay
It may also be possible to attach an item.

[0005]

In the present invention, since the inner stay is provided inside the vehicle body cover, the inner stay becomes a non-appearance member. Therefore, since the exterior member corresponding to the conventional carrier does not exist on the vehicle body cover at the rear of the seat, the appearance at the rear portion of the vehicle body is improved and the design process is facilitated.
Also, since the inner stay extends in the front-rear direction along the inside of the upper surface of the body cover behind the seat, even if force is applied to the body cover from the outside, it can be received by the inner stay and protects the body cover and the members inside it. it can. In particular, since it surrounds at least the upper side of the fuel tank, it serves as a protective member for the fuel tank. Further, when it is desired to carry the luggage on the body cover behind the seat, an optional member such as a trunk can be attached to the inner station, and as a result, the luggage cannot be directly carried on the body cover. .
