Description

Description Headlight support structure for motorcycles

Field of the invention

The present invention provides a motorcycle in which a headlight is attached to a synthetic resin handle cover for covering the handle, and a pair of direction indicator lights arranged on the left and right of the headlight are attached. In particular, the technology related to the improvement of the headlamp support structure

A headlight is mounted on the handle cover consisting of a synthetic resin lower cover that covers the bar handle from below and an upper cover made of synthetic resin that covers the bar handle from above. The structure to which the direction indicator light is attached is disclosed in Japanese Patent No. 2767240, in which the upper end of a plate-like supporting portion provided integrally with the lower cover is provided. Bearings for supporting the left and right support shafts of the headlight from below are provided in an approximately U-shape that opens upward, and a projection protruding from the lower part of the headlight allows the front and rear position to be adjusted so that the lower part can be adjusted. Fastened to the cover. By the way, the handle cover is composed of a synthetic resin front cover that covers the handle bar from the front side and a synthetic resin rear cover that covers the par handle from the rear side. In some cases, the headlamp is mounted so that the optical axis can be adjusted, and a pair of left and right direction indicators are mounted.In this case, if the conventional headlamp support structure as described above is adopted, the headlamp is molded from synthetic resin. The direction in which the front and rear covers are divided is orthogonal to the direction of movement of the mold for forming the bearing that supports the left and right support shafts of the headlight from below. Since it must be used, the manufacturing cost of the handle cover increases. Therefore, it is necessary to realize a structure that supports the headlight without using a slide type. At that time, we want to avoid complicating the shape of the handle cover.

The present invention has been made in view of such circumstances, and in a motorcycle in which a handle cover is constituted by a front and a rear cover, it is possible to avoid using a slide mold when molding the front and rear covers. With simple shape of each hippo It is an object of the present invention to provide a headlight supporting structure capable of swingably supporting a headlamp.

Disclosure of the invention

In order to achieve the above object, the present invention provides a handle cover for covering a bar handle, a synthetic resin front cover for covering the bar handle from the front side, and a synthetic resin rear cover for covering the par handle from the rear side. A motorcycle in which a headlight is mounted on the front cover so that the optical axis can be adjusted, and a pair of directional indicators arranged on the left and right of the headlight are mounted on the motorcycle. A pair of support shafts which are supported from the front and rear between a pair of first bearing halves provided on one side of the cover and a pair of second bearing halves provided on the two-way indicator light so as to be swingable. However, the first feature is that it is coaxially protruded on both the left and right sides of the headlight.

According to such a configuration, a pair of spindles provided with the headlights coaxially on the left and right sides are sandwiched from the front and rear by the pair of first and second bearing halves, respectively. The first bearing half provided on one of the front and rear covers is formed so as to be swingable, and is formed in the same direction as the mold split direction at the time of forming the front and rear covers. Therefore, a slide mold is not required, and the manufacturing cost of the handle cover can be reduced.Moreover, the first bearing half can be of a simple shape facing one of the mold split directions. The shape of the front and rear covers can also be simplified. In addition to the configuration of the first feature, the present invention further comprises mounting the directional lights on the front cover above the respective directional lights. Mounting portion for mounting, and the first portion adjacent to the mounting portion The second feature is that the two bearing halves are projectingly connected to each other. According to such a configuration, the half of the second bearing half that supports the half of the support shaft of the headlamp is provided. Since the turn signal light is attached to the front cover, the support rigidity of the support shaft by the second bearing half can be increased.
