The inner lens 5 provided with the light guide pipes 5b and 5c and the light diffusing portion 5d is respectively irradiated, and the light from the inner lens 5 is radiated to the outside through the outer lens 4. In this case, the inner lens 5 is provided with a function of emitting long light from the left-right direction. For this reason, while long light is radiated from the side turn lamp 2 in the left-right direction, the inner housing has a complicated shape or a reflector function, as in the conventional side turn lamp. It is not necessary to prepare a plurality of light source units, the structure can be simplified, and the number of parts can be reduced. In addition, the light emission state can be changed by changing the design of the inner lens 5, and a side turn lamp (vehicle lamp) having excellent design properties can be formed.
In addition, when the side turn lamp 2 is turned off, the interior member may be seen through the lens base portion 5a of the outer lens 4 and the inner lens 5 which are transparent members, but the design may be impaired. Since the inner housing 6 is provided between the inner lens 5 and the light source unit 7, the light source unit 7 is covered with the inner housing 6 which is a non-transparent member, and members such as the substrate 7e and the bus bar 7f of the light source unit 7 are covered. It cannot be seen from the outside, and the design is not impaired. Further, since the light source unit 7 supported by the inner housing 5 is disposed between the outer housing 3 and the light source unit, the light source unit is disposed at one end of a conventional long light guide. In addition, it is not difficult to secure the installation space, and the degree of freedom in design is increased.

  Moreover, in this case, the inner lens 5 is provided with a lens base portion 5a, a pair of upper and lower light guide pipes 5b and 5c, and a light diffusion portion 5d, which are first to fourth light sources 7a, 7b and 7c, respectively. , 7d, so that long light can be emitted integrally in the left-right direction, the design is excellent, and the side turn lamp 2 requires a legally required illuminance. Is emitted from the light diffusing portion 5d and has high visibility and functionality, but also has excellent design.

  Of course, the present invention is not limited to the embodiment described above, and half mirror deposition may be performed on the front surface (outer lens side) of the lens base portion of the inner lens. In this case, when the vehicle lamp is turned off, the light source exposed from the inner housing cannot be seen, and the design is further improved. At the time of lighting, the half mirror vapor deposition part functions as a reflecting surface, and the side turn lamp Can be emitted with higher visibility.
