Further, the mirror surface of the second reflecting mirror portion 37 b of the base 37 is constituted by a plurality of reflecting surfaces 58 A to 58 E which are substantially radially divided around the turn signal valve 39. Since there are step surfaces 59 A to 59 E formed between the reflection surfaces 58 A to 58 E, a mirror surface is composed of multiple reflection surfaces 58 A to 58 E that can change the focal length. By doing so, the degree of freedom in the design of the mirror surface can be increased, and the step surfaces 59A to 59E can also be effectively used as reflection surfaces. That is, even if the left and right widths of the second reflector 37 b are narrow, it is possible to obtain the same amount of parallel reflected light as in the prior art, and thus the width of the mirror surface of the second reflector 37 b is reduced, The overall lya combination lamp 35 can be made slimmer.

Moreover, the focal length of the reflective surfaces 58D, 58E outside the turn signal bulb 39 is set longer than the focal length of the reflective surfaces 58B, 58C inside the win force valve 39. Therefore, it is possible to improve the visibility from the lateral direction when the win force valve 39 is turned on.

The embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments, and various design changes can be made without departing from the present invention described in the claims. It is possible.
