In FIG. 1, reference numeral 5 denotes a light source bulb. The light source bulb 5 is detachably attached to the bulb holder of the reflector 4 through the through hole 11 of the lamp housing 1, and is disposed in a lamp room 50 described later. A bellows-shaped cap 51 is detachably mounted between the light source bulb 5 and the lamp housing 1. In addition, a shade 52 that blocks direct light from the light source bulb 5 is disposed in front of the light source bulb 5.

The automotive lamp of the present invention in the first embodiment has the above-described configuration, and the assembling process will be described below.

First, on a component assembly line. The lamp housing 1 and the radial core support 2 are integrally formed of resin. On the other hand, the lens 3 and the fender 6 are integrally molded with a transparent resin, and the body painting 60 is applied to the inner surface of the fender 6 of the integrally molded product of the lens 3 and the fender 6. Then, the shade 52 is fixed to the reflector 4, and the reflector 4 is attached to the lamp housing 1 by the optical axis adjusting mechanism 40 so that the optical axis can be adjusted. The light source bulb 5 is inserted into the through hole 11 of the lamp housing 1.
The light source bulb 5 is detachably attached to the bulb holder of the reflector 4 via the
A cap 51 is detachably attached between the lamp housing 1 and the lamp housing 1. Then, the lamp housing 1 and the lens 3
(At this time, the above-described lamp room 50 is defined). The mounting of the lamp housing 1 and the lens 3
It may be a detachable type or a fixed type. As a result,
A lamp unit is configured by the lamp housing 1, the lens 3, the reflector 4, the light source bulb 5, and the like.
The lamp unit, the fender 6 and the radial core support 2 are assembled.

Next, in an automobile assembly line. The lamp unit assembled with the fender 6 and the radio core support 2 in the assembly line of parts
By attaching the lamp unit to the vehicle body via the mounting seat 61 and the like, the lamp unit is mounted on the vehicle via the fender 6 and the radial core support 2.

As described above, in the automotive lamp according to the first embodiment of the present invention, the lamp unit is assembled in the assembly and production line of the automobile parts, and the assembled lamp unit and the fender 6 and the radial core support 2 are assembled. Is assembled, the assembling of the lamp unit with the fender 6 and the radial core support 2 is completed. This eliminates the need for assembling the lamp unit with the fender 6 and the radial core support 2 in an automobile assembly production line, thereby reducing the number of assembling steps and improving the assembling process.

Further, since the assembly of the lamp unit and the assembly of the lamp unit, the fender 6 and the radial core support 2 are performed on the same assembly production line, the lamp unit, the fender 6 and the radial core support 2 (or and The number of parts such as a bumper) for managing the gap between the vehicle body, the surface difference, the parallelism, and the like is reduced, and the dimensional control is made easier.

In particular, in the automotive lamp of the present invention in the first embodiment, the lens 3 and the fender 6
Since the lamp housing 1 and the radial core support 2 each have an integral structure, two parts become one part (four parts are two parts), and an assembling part for assembling the two parts becomes unnecessary. Is reduced and cost is reduced.

Further, since the lens 3 and the fender 6 and the lamp housing 1 and the radial core support 2 are integrally formed, the mounting rigidity between the lamp unit and the vehicle body is increased. A stable mounting state is constantly maintained. For this,
It is possible to prevent the optical axis from being shaken by an external force such as vibration or impact.

Further, since there is no need to provide a gap between the lens 3 and the fender 6, the appearance is good and the wind noise generated by the gap can be reduced. A joint member such as rubber for filling is not required, and the cost can be reduced accordingly.

Furthermore, since the body coating 60 is applied to the inner surface of the fender 6 made of transparent resin, even if the outer surface of the fender 6 is slightly damaged, the body coating 60 does not come off. Therefore, the repair is performed easily and at low cost.

In this example, the lamp housing 1 and the radial core support 2 are integrated, but the lamp housing 1 and the radial core support 2 may be separate. In this example, the fender 6
However, the outer surface of the fender 6 or both the inner and outer surfaces may be coated with the vehicle body.

The automotive lamp according to the present invention in the first embodiment has the above-described configuration, and the operation and operation thereof will be described below. When the light source bulb 4 is turned on, the light from the light source bulb 4 is reflected by the reflection surface 41 of the reflector 40, is irradiated to the outside through the lens 3 in a predetermined light distribution pattern, and when the optical axis adjustment mechanism 40 is operated. The optical axis is adjusted.
