The lens 200 has mounting legs 20 on its periphery. The mounting legs 20 of the lens 200 are set in the recess 11 of the housing 100 with a packing 21 interposed therebetween, and the lens 200 is detachably attached to the housing 100 with a screw (not shown) or the like. The lens 200 is then disposed in the front opening 10 of the housing 100, and the lens 200 and the housing 10 are then fixed to each other.
0 defines the lamp chamber 22.

3 is a wedge type valve, this valve 3
is arranged in the above-mentioned lamp chamber 22.

4 is a grommet, and this grommet 4 is made of rubber or the like and is a U-shaped tube member. One end 40 of this grommet 4 is fitted onto the cylindrical portion 12 of the housing 100 to communicate with the inside of the lamp chamber 22, and the other end 41 of the grommet 4 is fitted onto the cylindrical portion 12 of the housing 100.
They are placed close to the rear side of the 0 and facing each other to communicate with the outside air.

The vehicle light constructed as described above is attached to the mounting hole 50 of the vehicle body 5 as a mounting body using screws or the like with the lens 200 of the vehicle light facing downward.

In addition, 6 in the figure is a license plate disposed below the above-mentioned vehicle lamp.

In such a vehicle lamp, the inside of the light chamber 22 communicates with the outside air via the grommet 4, so the bulb 3
When the inside of the lamp chamber 22 expands and contracts as the lights are turned on and off, outside air flows into the lamp chamber 22 through the grommet 4, or the air inside the lamp chamber 22 flows out through the grommet 4 to prevent breathing. perform an action. Further, since the open end 41 of the grommet 4 faces the rear part of the housing 100, rainwater can be prevented from entering the lamp chamber 22 from the open end 41 of the grommet 4 through the grommet 4.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional vehicle lamp, the open end 41 of the grommet 4 is opened close to the rear part of the housing 100, so that the license plate shown in FIG. When the lens 200 is installed facing downward like a lamp, the open end 41 of the grommet 4 is placed directly above the rear part of the housing 100.
will be located. Therefore, if rainwater accumulates on the rear part of the housing 100, the rainwater accumulated in the housing 100 may be sucked into the lamp chamber 22 through the grommet 4 when the lamp chamber 22 is used for absorption. Further, since no waterproofing means is provided around the open end 41 of the grommet 4, rainwater bounces off the rear part of the housing 100 that faces the open end 41 of the grommet 4, and the rainwater bounces around the open end 41 of the grommet 4. It may invade the end 41.

An object of the present invention is to provide a vehicular lamp that can reliably prevent rainwater from entering the lamp chamber even if the license plate lamp is mounted with the lens facing downward.

[Means for Solving the Problem] In order to achieve the above-mentioned object, the present invention provides a vehicle lamp that is used with the lens facing downward.
A bulb accommodating part and a waterproof side wall are provided at the rear of the housing at a distance from each other and protrude rearward, a waterproof part is provided between the bulb accommodating part and the waterproof side wall, and outside air is allowed to enter the lamp chamber in the waterproof part. Provide a communication path for communication,
One end of the grommet is connected to the opening on the outside air side of the communication passage, and the other end of the grommet is surrounded by the valve housing, the waterproof side wall, and the waterproof part in a posture such that the axial direction of the other end is approximately horizontal. It is characterized by being located in a space that is

[Function] The present invention can prevent rainwater from hitting the part of the grommet facing the open end by the valve storage part, waterproof side wall, and waterproof part arranged around the open end of the other end of the grommet. This prevents rainwater from rebounding and entering the open end of the grommet.

In addition, when the lamp is mounted with the lens facing downward with the grommet in a position where the axial direction of the opening end of the other end is approximately horizontal, the opening end surface of the grommet will be approximately vertical, and the portion facing the opening end of the grommet will also be It is vertical, so rainwater will not accumulate on the opposite side. For this reason, there is no risk that rainwater will accumulate in this opposing portion and be sucked into the lamp chamber through the grommet due to the absorption effect of the lamp.

Therefore, even in a vehicle light such as a license plate lamp that is mounted with the lens facing downward, rainwater can be reliably prevented from entering the light chamber.

[Embodiment] Hereinafter, an embodiment of a vehicle lamp according to the present invention will be described with reference to FIGS. 1 to 4.

This embodiment describes an example of a license plate lamp.

In the figure, the same reference numerals as in FIG. 5 indicate the same parts.

In the figure, 1 is a housing, and this housing 1 has recesses 11 widened at both left and right ends. A valve storage section 1 is located in the center of this housing 1.
3 is provided integrally protruding rearward, a cylindrical portion 14 is provided integrally within the housing portion 13, and a contact 15 is provided within the cylindrical portion 14. A wedge type valve 3 is removably set on this contact 15.
A plate-shaped waterproof side wall 16 is attached to one end of this housing 1.
is provided integrally protruding rearward at a distance from the storage portion 13. A slightly thicker plate-shaped waterproof portion 17 as a protector is installed between the housing portion 13 and the waterproof side wall 16 on one side of the housing 1.
3 and the waterproof side wall 16 to protrude rearwardly. An open end 18 that communicates with the outside is provided at the tip of the waterproof part 17 in a direction perpendicular to the direction in which the waterproof part 17 projects. One end of this waterproof part 17 is a light chamber 22.
A communication path 19 is provided, which communicates with the inside and whose other end communicates with the outside via the open end 18.

2 is a lens, and mounting pieces 2 are attached to both ends of this lens 2.
3 are integrally installed. Mounting piece 23 of this lens 2
is set in the wide recess 11 of the housing 1 with a packing 21 interposed therebetween, and the vehicle lamp of the present invention is attached to the vehicle body 5 using the mounting piece 23 using screws 24 or the like.

Thus, one end 40 of the grommet 4 is fitted onto the open end 18 of the housing 1, and the other open end 41 of the grommet 4 is aligned in the axial direction X-
In a posture where X and the optical axis Y-Y of the lamp are almost perpendicular,
In other words, the storage portion 13 of the housing 1 is placed in a posture in which the axial direction XX of the other end is substantially horizontal.
It is located in a space 42 surrounded on three sides by a waterproof side wall 16 and a waterproof section 17.

Since the vehicle light of the present invention in this embodiment has the above-described configuration, the vehicle light of the present invention is mounted on the vehicle body 5 above the license plate 6 with the lens 2 facing downward and used as a license plate lamp. . Then, since the open end 41 of the grommet 4 is surrounded on three sides by the storage section 13, the waterproof side wall 16, and the waterproof section 17 of the housing 1, rainwater tends to enter the space 42 where the open end 41 of the grommet 4 is located. The above-mentioned storage part 1
3. This can be prevented by the waterproof side wall 16 and the waterproof part 17. For this reason, rainwater can be prevented from rebounding against the portion of the grommet 4 facing the open end 41 and from entering the open end 41 of the grommet 4.

In addition, since the open end 41 surface of the grommet 4 and the waterproof part 17 of the housing 1, which the open end 41 faces, are perpendicular, rainwater can run over the housing part 13, the waterproof side wall 16, and the enclosure of the waterproof part 17. Even if rainwater enters the space 42, it will flow down and
Rainwater does not accumulate in the waterproof portion 17 of the housing 1 facing the open end 41 of the grommet 4.
Therefore, rainwater does not collect in the waterproof part 17 and is not sucked into the lamp chamber 22 through the grommet 4 due to the absorption function of the lamp.

Therefore, even in the case of a vehicle light such as a license plate lamp that is mounted with the lens facing downward, rainwater can be reliably prevented from entering the light chamber.

[Effect of the invention] As is clear from the above, the vehicle light according to the present invention prevents rainwater from entering the light chamber, even if the vehicle light is installed with the lens facing downward, such as a license plate lamp. It can definitely be prevented.
