(57) [Summary] [Purpose] To improve the assemblability of the grommet that is attached to the breathing port of the lamp body. A grommet for a vehicular lamp that is attached to a breathing port 2a of a lamp body 1 to prevent rainwater and the like from entering the lamp body 1. A grommet body 4a formed of soft rubber has a hard filter 4b is provided, and the rigidity of the grommet body 4a is increased by the hard filter 4b, so that the grommet 4 is attached to the breathing port 2a of the lamp body 1.
The assemblability when mounting is improved.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a grommet for a vehicle lamp having an improved assembling property.

[0002]

[Prior Art]

 BACKGROUND ART Conventionally, a vehicular lamp used for a headlight or a rear lamp of an automobile includes a lamp housing in which a lamp body houses a lamp and a lens liquid-tightly bonded to an opening of the lamp housing by a hot melt. However, the interior of the lamp itself has a sealed structure.

Therefore, when the lamp is lit, the expanded internal air is exhausted to the outside air, and as the internal air contracts due to the extinguishment of the lamp, a breathing port for introducing the outside air into the inside opens in the rear surface of the lamp housing or the like. A grommet is attached to this breathing hole to prevent rainwater and the like from entering the lamp body.

The grommet has, for example, an L-shape or a U-shape and is formed of soft rubber or the like, and one end of the grommet is fitted into a tubular mouth portion protruding from the breathing mouth. For example, Japanese Utility Model Laid-Open No. 2-5809 and Japanese Utility Model Laid-Open No. 1-115105 have been proposed in which a filter is provided in the grommet to prevent dust and the like from entering the body of the lamp.

[0005]

[Problems to be solved by the device]

 Since the conventional grommet is molded from soft rubber, it has a bad assembling property because it is deformed when it is fitted into the mouth of the breathing port and is difficult to install.

Further, even if the filter is provided in the grommet, the filter is soft and the filter is movably provided in the grommet, so that there is a problem that the assemblability of the grommet is poor.

The present invention has been made in order to solve the above problems, and an object thereof is to provide a grommet for a vehicle lighting device having an improved assembling property.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is a grommet for a vehicle lamp, which is attached to a breathing port of a lamp body to prevent rainwater and the like from entering the lamp body. A hard filter is installed inside.

[0009]

[Action]

 Since the rigidity of the grommet body made of soft rubber is increased by the above configuration, the assembling property when the grommet is attached to the breathing port of the lamp body is improved.

[0010]

【Example】

 An embodiment of the present invention will be described in detail with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a lamp body, which comprises a lamp housing 2 and a lens 3 liquid-tightly adhered to an opening of the lamp housing 2 by hot melt. A reflector or a lamp (not shown) is provided in the lamp housing 2. It is housed.

A breathing port 2a is opened on the rear surface of the lamp housing 2.

A cylindrical mouth portion 2b is provided so as to project from the breathing mouth 2a, and one end of a grommet 4 for preventing rainwater and the like from entering the lamp body 1 is fitted into the mouth portion 2b. ing.

The grommet 4 is composed of a grommet body 4a which is formed into a substantially U-shape with a soft rubber and the like, and a hard filter 4b provided in an intermediate portion of the grommet body 4a.

The hard filter 4b prevents dust and the like in the air from entering the lamp body 1, and is formed of a hard porous material into a cylindrical shape, and is used when the grommet body 4a is molded. It is integrally molded with the grommet body 4a by mounting it in the mold in advance.

The hard filter 4b may be attached by means such as adhesion or sulfurization.

Next, the operation of the grommet 4 configured as described above will be described. Since the hard filter 4b is previously provided in the grommet body 4a formed of soft rubber or the like, the grommet body 4a is formed by the hard filter 4b. The rigidity of 4a is high.

With this, when the body portion of the grommet body 4a is held by a finger and one end is fitted into the mouth portion 2b of the breathing mouth 2a, the grommet body 4a is not easily deformed even if force is applied to the finger, which is easy. It is possible to greatly improve the assemblability of the grommet 4 such that it can be fitted into the mouth portion 2b.

[0019]

[Effect of the device]

 As described in detail above, this invention improves the rigidity of the grommet body by mounting a hard filter on the grommet body molded from soft rubber or the like. Problems such as the grommet body deforming and being difficult to fit can be improved, and workability during assembly can be greatly improved.

In addition, since the hard filter in the grommet main body removes dust in the air during use of the lamp, it is possible to prevent the dust from entering the lamp main body.
