However, in the above-described conventional vehicle lamp, the light sources 61 and 62 are simply arranged in the lamp chambers 31 and 32. Therefore, when the light sources 61 and 62 are not lit, Light rooms 31, 32 from the lens 21, 22 side
There is a problem that the light sources 61 and 62 can be seen when looking inside.

[0007] The above-described conventional vehicle lighting device includes a light room 3.
Since the light-emitting portions 41 and 42 and the dummy portions 51 and 52 are provided in the light-emitting portions 1 and 32, respectively, the depth of the light-emitting portions 41 and 42 (the distance between the lamp housings 11 and 12 and the lenses 21 and 22) T1 and the dummy sections 51, 5
2 is different from the depth dimension (dimension between the lamp housings 11 and 12 and the lenses 21 and 22) T2. For this reason, when the light sources 61 and 62 are not lit,
When viewing the interior of the lamp chambers 31 and 32 from the lenses 21 and 22 side, there is a problem that the light emitting units 41 and 42 having different depth dimensions T1 and T2 and the dummy units 51 and 52 look differently.

It is an object of the present invention to provide a vehicular lamp in which the light source in the lamp room is not visible when the light is not lit, and the light emitting portion and the dummy portion are seen at substantially the same depth, so that the appearance is improved. It is in.

[0009]

In order to achieve the above object, the present invention is characterized in that a half mirror is arranged between a light source of a light emitting section and a lens.

As a result, when the light source is not turned on, the light source is not seen from the lens side due to the semi-reflective semi-transmissive action of the half mirror, and when the light source is turned on, the vehicular lamp of the present invention does not emit light. Light is emitted to the outside through a half mirror and a lens in a predetermined light distribution pattern.

Further, the present invention is characterized in that the dimension between the half mirror and the lens in the light emitting section is substantially the same as the dimension between the lamp housing and the lens in the dummy section.

As a result, in the vehicular lamp of the present invention, when not lit, the light emitting portion and the dummy portion appear to have substantially the same depth. As described above, according to the present invention, the appearance at the time of non-lighting is improved.
