用照明灯を提供することを目的とする。 The present invention was made to solve the above problems, and the flange part of the lens is placed on the lens mounting part at the edge of the front opening of the housing, and the lens mounting part and the flange part are formed into a substantially C-shape. In a vehicle lighting lamp which is held under pressure with a clip, one end of the clip is formed into a substantially U-shape that can be elastically deformed, a clip insertion hole is formed at the clip position of the lens mounting part, and the clip is inserted into this hole. The one end is inserted through the hole in an elastically compressed state, and after the one end passes through the hole, it is elastically returned to engage with the back surface of the lens mounting part of the housing, and the mounting part of the housing and the flange of the lens are pressed together. It is an object of the present invention to provide a vehicle illumination lamp which has good assembly workability and can securely fix a lens by holding the lens.

以下、本考案を図示の実施例に基づいて詳細に

脱落が確実に防止される。 3 to 6 show an embodiment of the present invention, in which 1 is a housing, 2 is a lens, and 3 is a clip. The housing 1 is similar to the conventional one in that a shallow groove-shaped lens mounting portion 1A is formed at the edge of the front opening, but in this embodiment, the outer wall 1A ₁ at the clip position is thickened, and this A clip insertion hole 1B is formed in the portion. This clip insertion hole 1B is a long hole with a substantially rectangular cross section, the long side of which is about the width of the clip 3, and the short side of which has a size that allows the clip 3 to be inserted while compressing one end. . As a result, after attaching the clip 3, the lens 2 is attached to the lens mounting portion 1A of the housing 1.
The flange portion 2A is securely fixed, and the lens 2 is reliably prevented from falling off.

When one end comes out, the compression is released, and its elastic return force causes the tip to enter the back side of the flange 2A, and together with the pressing of the surface of the flange 2A by the other end, the lens mount 1A of the housing 1 and The flange portion 2A of the lens 2 is held under clamping pressure.

組付作業性が改善される。 As described above, according to the present invention, a clip insertion hole is formed at the clip position of the lens mounting portion of the housing, and the clip is inserted through the hole to hold the lens mounting portion of the housing and the flange portion of the lens with pinch pressure. As a result, the clip can be attached accurately,
It is possible to prevent the clip from coming off and, by extension, the lens from falling off. Moreover, the only way to assemble the clip is to push it into the insertion hole in one direction.
Assembly workability is improved.
