According to this configuration, the heat of the valve can be smoothly radiated from the heat radiation opening above the valve.

In the present invention, an opening is provided in the reflector close to the inside of the extension part, and the heat of the valve is guided to the extension part through the opening, so the temperature of the extension part is increased by the heat of the valve, and the temperature is low. Even at times, the lens can be prevented from being fogged, and since the opening is not visually recognized from the outside, a decrease in appearance can be avoided.
Further, since the heat conducting member is provided on the back surface of the extension portion, the effect of preventing fogging of the lens inner surface is further improved.
Further, since the heat conducting member is made of aluminum vapor deposition, the surface treatment of the inner surface of the extension portion can be made the same as the surface treatment of the reflecting surface of the reflector.

In addition, the extension part is provided on the side of the reflector integrally with the reflector, and the opening is located below the valve, so the number of parts is reduced and the entire extension part is efficiently made efficient by the natural rise of the heat of the valve. The temperature rises and the anti-fogging effect of the lens is further improved.
In addition, since the inner lens is provided inside the lens, the design of the vehicle lamp can be easily changed by changing the shape of the inner lens.
Further, since the heat radiation openings are provided in the upper part of the reflector and the lamp body, the heat of the bulb can be smoothly radiated from the heat radiation opening above the bulb.

By the way, when the outside air temperature is low, the inner surface of the outer lens 74 of the tail lamp unit 60 may be fogged due to condensation. Cloudiness due to condensation is likely to occur in both end areas (indicated by areas AR1 and AR2 in FIG. 5).
Therefore, in this configuration, as shown in FIG. 6, the opening 100 is formed in the first reflector portion 82A for the valve 80 in the side reflector portion 82A2 adjacent to the inner surface 84AN of the first extension portion 84A. Yes.
The opening 100 is formed at a position below the bulb 80 (for example, a height range between the vicinity of the bottom plate 75 and the bulb 80), and a gap α between the first extension portion 84A and the side reflector portion 82A2. The first lamp chamber LA in which the lamp 80 is disposed communicates with the lower position. Therefore, the radiant heat of the lamp 80 is guided to the inner surface 84AN of the first extension portion 84A through the opening 100.

In this configuration, aluminum is vapor-deposited as a heat conducting member on the inner surface 84AN of the first extension portion 84A.
With these configurations, the radiant heat of the lamp 80 is guided to the lower side of the inner surface 84AN of the first extension portion 84A through the opening 100, and then is transmitted through the aluminum deposited on the inner surface 84AN, so that the first extension portion. The entire temperature is rapidly increased from the lower side of 84A. For this reason, even if the temperature of the gap α1 (see FIG. 6) between the first extension portion 84A and the outer lens 74 rises and the outside air temperature is low, the area AR1 of the outer lens 74 (see FIG. 5A).

Is formed, and aluminum vapor deposition is performed on the inner surface 84BN of the second extension portion 84B.
For this reason, the radiant heat of the lamp 81 is guided from the second lamp chamber LB in which the lamp 81 is disposed to the lower side of the inner surface 84BN of the second extension portion 84B through the opening 110 and deposited on the inner surface 84BN. The temperature of the entire second extension portion 84B is quickly improved through the aluminum. Accordingly, the temperature of the gap β1 (see FIG. 6) between the second extension portion 84B and the outer lens 74 can be increased, and the area AR2 (see FIG. 5A) of the outer lens 74 even when the outside air temperature is low. )) And the surrounding area can be avoided and fogging of the outer lens 74 can be prevented.

8 is a cross-sectional view taken along the line dd in FIG. 5A, and FIG. 9 is a cross-sectional view taken along the line ee in FIG. As shown in FIG. 8, an opening 200A is provided in the upper part of the reflector 82, and as shown in FIG. 9, the opening is provided in the vicinity of the lamp 80 in the upper part of the wall 70B of the lamp body 70. A labyrinth portion 210 </ b> A communicating with 200 is provided. The labyrinth portion 210A has an air passage 210A1 bent in a substantially U-shape, and the opening 200A communicates with the outer space of the lamp body 70 through the air passage 210A1.
Further, as shown in FIG. 8, an opening 200B is also provided in the lower part of the reflector 82, and as shown in FIG. 9, the position near the lamp 81 in the lower part of the collar wall 70B of the lamp body 70 is as described above. A labyrinth portion 210B communicating with the opening portion 200B is provided. Similarly to the labyrinth portion 210A, the labyrinth portion 210B also has an air passage 210B1 bent in a substantially U shape, and the opening portion 200B communicates with the outer space of the lamp body 70 through the air passage 210B1.

  Therefore, an air passage that connects the lamp chamber L in the lamp body 70 and the space outside the lamp body 70 is formed by the openings 200A and 200B and the labyrinth portions 210A and 210B, and the lamp 80 in the lamp chamber L, The heat of the lamps 80 and 81 is released to the outside through the opening portion 200A of the reflector 82 and the labyrinth portion 210A of the lamp body 70 in order by the air convection generated by the heat generation of the 81, and the outside air is discharged to the lamp body 70. An air circulation path is formed such that the air circulation path passes through the labyrinth portion 210B and the opening portion 200B of the reflector 82 and flows into the lamp chamber L in order, so that heat can be radiated smoothly. In this case, it is possible to prevent water or the like from entering the lamp chamber L from the outside by the air passages 210A1 and 210B1 of the labyrinth portions 210A and 210B.

As described above, in the present embodiment, as shown in FIG. 6, the first extension portion 84A that covers the space between the first reflector portion 82A and the lamp body 70 is provided, and the first extension of the first reflector portion 82A is provided. Since the opening portion 100 is provided at a position close to the inside of the portion 84A, the radiant heat of the bulb 80 can be guided to the inner surface 84AN of the first extension portion 84A through the opening portion 100 to raise the temperature of the second extension portion 84A. Even when the temperature is low, fogging due to condensation in the area AR1 of the outer lens 74 in the vicinity of the first extension portion 84A can be prevented.
Thus, since the opening part 100 is provided inside the first extension part 84A, the opening part 100 is not visually recognized from the outside by the first extension part 84A. For this reason, the appearance is not deteriorated as compared with the conventional one in which an opening is provided in the extension part, and the degree of freedom of the shape of the first extension part 84A and the first reflector part 82A is limited. It will not be done.

In addition, since the aluminum deposition is performed on the inner surface 84AN of the first extension portion 84A, the heat guided to the first extension portion 84A can be quickly transferred to the whole. Furthermore, since the opening 100 is provided on the lower side of the outer lens 74, the temperature of the entire first extension portion 84A can be efficiently raised by the natural rise of radiant heat, and the clouding prevention effect of the area AR1 of the outer lens 74 can be achieved. Can be further improved.
Further, the first extension portion 84A is formed integrally with the first reflector portion 82A, and the same aluminum vapor deposition as that applied to the reflection surface of the first reflector portion 82A is performed on the inner surface 84AN of the first extension portion 84A. Therefore, the number of components can be reduced, and the reflection surface and the heat conduction surface can be created by a common surface treatment, which facilitates the production.

In this configuration, the second reflector portion 82B that reflects the illumination light of the bulb 81 is also provided with an opening 110 below the side reflector portion 82B2, and from the side reflector portion 82B2 to the outer lens 74 side. Since the second extension portion 84B is formed so as to extend, the radiant heat of the bulb 80 can be guided to the inner surface 84BN of the second extension portion 84B through the opening portion 100 to increase the temperature of the second extension portion 84B. Even when is low, fogging due to condensation in the area AR2 of the outer lens 74 in the vicinity of the second extension portion 84B can be prevented.
Also in this case, since the opening portion 110 is provided in the side reflector portion 82B2 that is not visible from the outer lens 74 side, the opening portion 110 is not visible from the outside. Compared with the conventional one provided with the opening, the appearance is not deteriorated, and the degree of freedom of the shape of the second extension portion 84B and the second reflector portion 82B is not limited.

In the second extension portion 84B, as in the first extension portion 84A, the inner surface 84BN is vapor-deposited with aluminum and the opening 110 is provided on the lower side of the outer lens 74. Therefore, the area AR2 of the outer lens 74 is provided. The anti-fogging effect can be further improved.
Further, the second extension portion 84B is formed integrally with the second reflector portion 82B, and the inner surface 84BN is subjected to the same aluminum vapor deposition as that applied to the reflection surface of the second reflector portion 82B, thereby providing a heat conducting surface. As a result, the number of parts can be reduced, and the reflecting surface and the heat conducting surface can be created by a common surface treatment, facilitating manufacture.
In addition, since the inner lenses 83A and 83B are provided in front of the bulbs 80 and 81, the design of the tail lamp can be easily changed by changing the shape of the inner lenses 83A and 83B.
The extension portions 84A and 84B may be provided separately from the reflector 82.
