Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front body cover which facilitates assembly of a scooter type vehicle.

[0002]

2. Description of the Related Art Japanese Utility Model Laid-Open No. 63-50788 discloses a front body cover for a scooter type vehicle which is divided into two parts, a front part and a rear part.
A mating line is shown between the back of the front cover and the front of the back cover.

Further, in Japanese Unexamined Patent Publication No. 4-331685, a front cover forming an outer appearance on the front side, a back cover of the front cover, and a middle cover part of which also serves as a front fender, and a back surface of the middle cover are combined. , And a front body cover divided into three parts, namely, a rear cover forming an outer appearance surface on the back side. The upper end of the middle cover that constitutes the front body cover is located at each intermediate portion of the front and rear covers, and the alignment line of the front cover is formed between the middle cover and the upper portions of the rear cover.

[0004]

By the way, in the case of a scooter with a roof or the like, the front body cover may be large, and it may be divided for maintenance and manufacturing convenience. However, when divided into three as in Japanese Patent Laid-Open No. 4-331685, since the front cover has a matching line for both the middle cover and the rear cover, there is a place where these three members meet at one place.

Therefore, in order to accurately align such three members, there is a problem that the dimensional accuracy of each member is extremely high and that a laborious alignment work is required. Therefore, the present invention solves such a problem.

[0006]

In order to solve the above problems, a front vehicle body cover of a scooter type vehicle according to the present application is a front vehicle body cover provided for covering a vehicle body front portion of a scooter type vehicle, A front cover that forms the exterior surface of the front side,
An upper end portion of the middle cover, which is divided into three parts, that is, a middle cover that is combined with the back surface of the front cover and part of which also serves as a front fender, and a rear cover that is combined with the back surface of the middle cover and forms an exterior surface on the rear side. Is extended upward to the same height as the upper end of the front cover, and the alignment line of the front cover is formed only between the front surface of the middle cover.

[0007]

When the front surface of the middle cover is aligned with the back surface of the front cover, the heights of the upper ends of the front cover and the middle cover are the same, so that the alignment line of the front cover is only between the middle cover and the front cover. When the front surface of the rear cover is aligned with the rear surface of the inner cover, the rear cover is also aligned with only the inner cover in one alignment line.

[0008]

According to the present invention, since the heights of the upper ends of the middle cover and the front cover are matched with each other, the back surface of the front cover can be matched with the front surface of the middle cover by one alignment line. Therefore, even if the front body cover is divided into three parts,
Since it is not necessary to match the front cover with the rear cover and it is not necessary to match the three members at one place as in the known example, the dimensional accuracy required for each member can be relaxed, and the matching work is easy and quick. , Workability is improved.
