DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a storage box for a motorcycle, and more particularly to a structure of a top opening of a storage box disposed between left and right frame members behind a head pipe.

[0002]

[Prior art]

In a motorcycle, a storage box is provided between a pair of left and right frame members extending rearward from a head pipe.Conventionally, as a fuel tank-shaped storage box, a storage box is provided at a portion bulging upward from between the two frame members. It is common to form an opening and provide a lid member that allows the opening to be opened and closed.

[0003]

However, the opening for taking in and out the luggage is located in the upwardly swelling portion and is a relatively narrow opening, so that it is difficult to take in and out a large luggage, and the opening and closing of the lid member is difficult. The sealing measures at the joints were also troublesome.

Accordingly, an object of the present invention is to provide a motorcycle having a storage box between left and right frame members behind a head pipe, in which the opening on the upper surface of the storage box is enlarged so that large luggage can be easily taken in and out. Another object of the present invention is to provide a storage box which is advantageous in terms of measures for sealing a portion where the frame is joined with the member and which can be supported on the upper surfaces of both frame members.

[0005]

[Means for Solving the Problems]

In order to solve the above problems, the present invention relates to a motorcycle in which a storage box is disposed between a pair of left and right frame members extending rearward from a head pipe, wherein a shape substantially corresponding to a space between the two frame members is provided on an upper portion of the storage box. The inclined surface is extended obliquely downward from the periphery of the opening, the flanges along the upper surfaces of the two frame members are extended from the lower end of the inclined surface, and the upright portion is formed from the peripheral edge of the flange. The inclined surface, the flange portion, and the upright portion form a concave portion, a seal rubber is provided in the concave portion, and the lower peripheral portion of the lid member closing the opening is pressed by the seal rubber. It is characterized in that the contact portion of the storage box and the lid member is sealed by contacting.

The storage box opening has a large shape substantially corresponding to the space between the two frame members, so that even large luggage can be easily taken in and out. By providing the seal rubber in the recess, the seal rubber can be easily and reliably mounted in the recess.

In addition, by extending the flanges along the upper surfaces of the two frame members, the flanges are firmly supported by the two frame members, and the sealing performance of the joint between the storage box and the lid member by the seal rubber is enhanced. Furthermore, by extending the inclined surface obliquely downward from the periphery of the opening, when closing the opening with the lid member, the lower peripheral edge of the lid member is easily guided along the inclined surface to the upper part of the seal rubber in the recess. This ensures that the joint between the storage box and the lid member is sealed.

【The invention's effect】

As described above, according to the present invention, in the motorcycle having the storage box between the left and right frame members behind the head pipe, the opening of the storage box has a large shape substantially corresponding to the space between the two frame members. However, it can be easily put in and out. Since the seal rubber is provided in the recess, the seal rubber can be easily and reliably mounted in the recess.

In addition, since the flanges extending along the upper surfaces of both frame members are extended, the flanges can be firmly supported by both frame members, and the sealing performance of the joint between the storage box and the lid member by the seal rubber can be improved. Can be enhanced. Furthermore, since the inclined surface is extended obliquely downward from the periphery of the opening, when closing the opening with the lid member, the lower peripheral edge of the lid member is easily guided along the inclined surface to the upper portion of the seal rubber in the concave portion. This makes it possible to reliably seal the joint between the storage box and the lid member.
