(See Publication No. 189).

[Problem that the invention seeks to solve]

In the case of the conventional structure described above, since the headlight and the flasher lamp are each separate parts, there is a problem that the number of parts and the number of assembly steps are correspondingly large.

In addition, there is no sense of continuity between the lens surfaces, and differences in level are likely to occur due to mounting errors, resulting in poor appearance.

Furthermore, in order to ensure alignment accuracy between the divided handle covers and between the handle cover and each light II, it is necessary to increase the rigidity of the handle cover, and for this purpose conventionally, reinforcing ribs are provided on the handle cover. ing. However, when the ribs are provided, there is a problem that sink marks are likely to occur on the cover surface, and there is also a problem that the layout of parts inside the cover is restricted by the ribs.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a headlight device for motorcycles and tricycles that can reduce the number of parts and assembly man-hours, and improve the appearance and assembly workability. It is said that

[Means for solving problems]

The present invention features a handlebar cover that is divided into multiple parts that surrounds the handlebar, and includes a headlight and a left handlebar.

In a headlight device for a motorcycle or tricycle, which includes a right pair of flasher lamps arranged side by side, the lens of the headlight and the lens of the flasher lamp are integrally formed, and the body of the headlight and the flasher lamp are integrally formed. By integrally forming the headlight and the flasher lamp with the body of the lamp, the headlight and the flasher lamp are integrated into one unit to form a headlight unit, and the headlight unit is inserted into the opening provided in the handle cover. It is also characterized in that it is fixed to the above-mentioned handle cover.

Here, the body in the present invention means a reflector holding member for a headlight, and a flaper holding member or a flapper itself for a flasher lamp.

In addition, the handle cover of the present invention includes a handle cover divided into upper and lower covers, a front cover and a rear cover divided into two,
Further, the method of fixing the headlamp unit includes fixing it to either one of the covers or fixing it to both covers.

[Effect]

According to the headlamp device according to the present invention, the headlight and the flasher lamp are integrated into one unit, and this headlamp unit is installed inside the handle cover.
The number of assembly steps per part can be reduced. Furthermore, it is possible to easily create a sense of unity on the lens surface, and the variation in the gap between the handle cover and the lens can be reduced, resulting in a better appearance.

Further, in the present invention, since a headlight unit having relatively high rigidity, which is a unit of a headlight and a flasher lamp, is fixed to the handle cover, the rigidity of the handle cover itself is increased over substantially the entire width. Therefore, the accuracy of fitting the divided handle covers is improved, and the ease of assembly is improved.

Additionally, since the handle cover is reinforced by the headlight unit, the amount of reinforcement needed can be significantly reduced.

According to the headlight device according to the present embodiment, the headlight, the lens and body of the flasher lamp are integrally formed to constitute the headlight unit 38, and this is inserted into the mounting opening of the handle cover 31. Therefore, the number of parts and the number of assembly steps can be reduced. In addition, since the head lens part 38a and the Francia lens part 38b are integrated, it is possible to easily create a sense of unity between the lens surfaces, and each cutout part 3'lc, 33d of the handle cover 31 and the lens can be easily created. 3
The variation in the gap with 8 can also be reduced, and the appearance will be that much better. Here, in order to integrate the head lens part 38a and the flasher lens part 38b, it becomes necessary to color the flasher lens part 38b, and there is a concern that the number of manufacturing steps will increase.6 In this embodiment, the flasher lamp 40b is surrounded by the orange inner lens 40a,
The entire lens 38 can be configured in the same color, and an increase in manufacturing man-hours can be avoided.

Furthermore, since the headlight and flasher lamp are integrated into a unit, the headlight unit 37 has increased rigidity over the entire width of the handle cover 31, and this highly rigid headlight unit 37 is fixed to the lower cover 33. Therefore, the rigidity of the lower cover 33 itself is increased over substantially the entire width. Therefore, the lower and upper covers 33
．． 32 alignment accuracy is improved, and assembly work efficiency is improved.

Furthermore, since the handle cover 31 is reinforced by attaching the headlight unit 37, there is no need to provide a special reinforcing lip.Therefore, it is possible to avoid the problem of deterioration of the appearance due to sink marks caused by the ribs, and there is no need to install other parts inside the handle cover 31. The degree of freedom in layout can be expanded when arranging vehicle parts.

Furthermore, the optical axis adjustment in the apparatus of this embodiment is performed by swinging the reflector 41 up and down with respect to the body 39 using an adjustment bolt 43b.
