Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a front fender attachment structure that is optimal for, for example, a scooter-type motorcycle or a tricycle, and particularly relates to improving the ease of attaching and detaching the front portion of a movable front fender.

[Conventional technology]

Conventionally, particularly in scooter-type motorcycles and tricycles, it has been common practice to cover the upper part of the front wheel with a front fender and to cover the front of the occupant's legs with a leg shield.

If the front fender of such a scooter-type motorcycle or tricycle is damaged due to, for example, a collision, it must be removed and repaired, or replaced with a new one. On the other hand, when considering damage to the front fender, there is a higher possibility that the front fender will be damaged than the rear half. Therefore, repair costs can be reduced by creating a structure in which only the front half can be attached and removed separately from the rear half.

Therefore, conventionally, the front fender has been made into a so-called front-rear split type consisting of a front part and a rear part, and the front fender has a structure in which this front part is detachably attached to the front fork. Only parts can be replaced,
Repair costs can be reduced.

[Problem that the invention seeks to solve]

However, especially in scooter-type motorcycles and tricycles, when mounting the front fender on the front half of the front fender, the leg shield is located near the front fender and covers the mounting section, so that the mounting section is hidden. In order to attach and detach the parts, it is first necessary to remove the leg shield, which poses a problem in that the workability of attaching and detaching is poor. In order to improve this workability, it is possible to form a tool insertion hole in the leg shield to warm the front fender mounting bolt, but if this is done, there will be no openings in the leg shield that are unnecessary due to design and functionality. This may result in deterioration of the three appearance functions.

Therefore, an object of the present invention is to provide an automatic opening for attaching and detaching the front half of the front fender to improve workability by easily attaching and detaching the front half of the front fender without removing the leg shield or providing a dedicated tool insertion opening. The point is to provide structure.

[Means for solving problems]

The present invention provides a motorcycle or tricycle equipped with a movable front fender and a leg shield having a relief part to avoid interference with the front fender during steering operation, in which the front fender is divided into front and rear parts, and the rear half of the fender is Attach the part to the front fork, and fix it to the front fork or the support bracket formed on the rear half of the fender with a mounting member to the upper left and right sides of the rear edge of the front half of the fender. The lower mounting part is fixed to the front edge of the rear half of the fender or to the support bracket formed on the front fork, and the right and left mounting members on the upper part of the rear edge are used to attach the steering handle to the left and right sides, respectively. The front fender mounting structure is characterized in that when the fender is rotated to the right, it is located at a position that faces forward through the relief part of the leg shield.

Here, the mounting member for fixing the above-mentioned upper mounting section refers to a removable coupling means such as a bolt naft 1 or a resin rivet, and the lower mounting section is fixed with a bolt nand, a resin rivet, or It is only necessary to attach the belts to each other, and the means for doing so is not particularly limited.

[Effect]

In the structure of attaching the automatic door to the front fender of a tricycle according to the present invention, when attaching or detaching the front half of the front fender, the steering handle is rotated to the left or right. Then, the right or left mounting member of the upper mounting part of the front half of the fender will face forward through the relief part of the leg shield, and if you insert the tool guide using this relief part, the above installation ←-→ Therefore, the front half of the fender can be easily attached and detached. In this case, instead of providing a special opening for inserting tools, the leg shield uses a conventional relief part to prevent interference with the front fender during steering operations. Therefore, the appearance does not deteriorate the function.
