Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a front fender attachment device for a motorcycle.

In a conventional front fender mounting device for a motorcycle, mounting seats are provided protruding from the front and/or rear sides of the left and right outer tubes of the front fork, and a connecting member is spanned between the mounting seats.
A bolt is passed through the bolt hole of the connecting member from above,
There is one in which the bolt is screwed into a screw hole in the mounting seat to fix the connecting member to the mounting seat, and a front fender is fixed to the lower surface of the connecting member.

The above-mentioned conventional front fender mounting device has the disadvantage that since the mounting seats are provided on the front or rear side of the outer tube, the connecting member spanning between the mounting seats becomes long, which impairs the appearance of the mounting device. Also,
The connecting member can be shortened by providing a mounting seat protruding from the wheel-side portion of the outer tube so that the connecting member is fixed by spanning between the mounting seats with both ends touching the top surface of the mounting seat. Although it has a sleek appearance, the mounting seat protruding toward the wheel side on the outer tube gets in the way and limits the shape of the front fender.

The present invention has been made in view of the above circumstances, and includes mounting seats protruding from the wheel-side portions of the left and right outer tubes of the front fork, each of which has an upper surface, an end surface facing each other, and a lower surface. , in a front fender mounting device in which a connecting member is bridged and fixed between mounting seats with both ends touching the upper surface of the mounting seat, and a front fender is attached to the lower surface of the connecting member between the mounting seats, the front fender is attached to the outer tube. The part of the front fender that faces the installed mounting seat has a hanging part located with a small distance between it and the end face, and a hanging part that is continuous with the hanging part and extends slightly downward from the bottom surface of the mounting seat. The connecting portion extends apart and has an outer edge located close to the wheel-side surface of the outer tube, and is designed to approximately correspond to the shape of the mounting seat.

Therefore, in the device of the present invention, since the part of the front fender that faces the mounting seat protruding from the outer tube has a shape that approximately corresponds to the shape of the mounting seat, it is possible to increase the amount of protrusion of the mounting seat, Even if the thickness of the seat is increased, the width of the front fender can be made to be the full width between the outer tubes, and the connecting member, the mounting seat, the front fender, etc. can be given a unified appearance.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the front fender attachment device for a motorcycle according to the present invention will be described in detail below with reference to the accompanying drawings.
