DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicular lamp in which a light source and a reflector having a substantially parabolic shape are housed in a lamp body, for example, because the specifications of the reflector required for each destination country are different. The present invention relates to a vehicular lamp in which a reflector having a slightly different shape needs to be attached to a lamp body having the same shape for each destination country.

[0002]

2. Description of the Related Art Even for the same type of vehicular lamp, specifications may differ depending on the destination country. For example, the shape of the effective reflection surface of the reflector required for each destination country may be different. In such a case, as shown in FIG. 6A, the reflection surface which is a reflector is provided inside the lamp body 1a. As shown in FIG. 6 (b), the reflector 2 is formed integrally with the lamp body 1a.
b is known. Reference numeral 3 denotes a bulb serving as a light source, and reference numeral 4 denotes a front lens.

There is also known a lamp having a structure shown in FIG. 6 (b) in which a reflector 2b to be housed in the same lamp body has a different shape depending on a destination country.

[0004]

However, the above-described first method
In the prior art, since the lamp structure is completely different depending on the destination country, it is troublesome to prepare lamps having completely different components such as a lamp body, a reflector, and a lens even though the lamps are originally of the same kind. There was.

In the second prior art, since the lamp body as a lamp component is shared, the manufacturing cost is reduced accordingly. However, when a reflector having a different shape is attached to the lamp body, the reflector on the lamp body side is required. Since the reflector supporting surface is small, it is difficult to position the reflector, and there is a problem that workability is poor. The present invention has been made in view of the above-described problems of the related art, and its object is to provide a reflector having a different shape in a case where a reflector having a slightly different shape is accommodated in a lamp body for each destination country. An object of the present invention is to provide a vehicular lamp that can be easily accommodated.

[0006]

In order to achieve the above object, in a rear combination lamp according to the present invention, a pair of juxtaposed lamp rooms is defined by a lamp body space defined by a lamp body and a clear front lens . A light source and the

[0007]

Since the rear wall of the lamp body has substantially the same shape as the paraboloid of the reflector and is in contact with the reflector, the lamp body, that is, the lamp, is compact.
In addition, since the reflector rear surface and the lamp body rear wall have substantially the same curved surface, the reflector can slide along the lamp body rear wall when the lamp is assembled .

17b and the lamp body rear walls 10b ₁ and 10b ₂ are formed in substantially the same curved shape, so that the inner lens
When assembling the lamp body 10 to the outer lens 30 containing the reflector / extension assembly, the reflector back wall 16b (17b) and the lamp body back walls 10b ₁ , 10b ₂ slide relative to each other, and the lamp body 1
The reflector unit 15 (reflectors 16 and 17) smoothly fits into a predetermined position where the concave / convex engaging portions 10c and 15c for positioning between 0 and the reflector unit 15 are engaged.

If the destination country is different, a reflector 16A having only a part of the shape shown by the phantom line in FIG. 3 is mounted in the lamp room space.
_{Since 1} is also a shape substantially following the rear shape of the reflector 16A, even if the reflector 16A has a slightly different shape from the reflector 16 used in the first specification,
During assembly of the lamp, the reflector 16A is slid along the inner peripheral surface of the lamp body rear wall 10b _1, the reflector-side protrusion 15c and the lamp body side recess 10c fits smoothly into place engaging Therefore, there is no problem in assembling the lamp.

[0015]

As is apparent from the above description, according to the rear combination lamp of the present invention, the rear wall of the lamp body is formed in substantially the same shape as the paraboloid of the reflector, and is in contact with the reflector. Therefore, the lamp becomes compact. Also, since the back of the reflector and the back of the lamp body have almost the same curved surface, the lamp is assembled.
At the time of reflection , the reflector can slide along the rear wall of the lamp body, and even if the reflector has a slightly different shape for each destination country, it can be smoothly fitted into the lamp body, and the lamp can be easily assembled.
