As described in detail above, the present invention includes an engaging part and an elastic holding part that hold a bowl-shaped reflector on the inner and outer surfaces, which are integrally formed on a plate-shaped part of a support, and in which the engaging part extends along the circumferential direction. The reflector has a groove through which the engaging portion is inserted, an engaging step portion into which the engaging piece of the engaging portion engages, and a circumferential step portion that abuts on the elastic holding portion. In addition to effectively preventing the reflector from tilting, the positional relationship between the lamp and the reflector does not change even if the dimensions of the reflector vary due to molding variations, and variations in light distribution can be effectively prevented. . In addition, the reflector can be formed using a cutting die that is easy to mold, making it easy to manufacture. Furthermore, the reflector can be easily attached to the support by a rotational operation.
