PROBLEM TO BE SOLVED: To improve the outward appearance of a lighting fixture when a bulb socket is fit to a reflector or the like and make the bulb socket small. SOLUTION: The bulb socket 4 is equipped with a cylindrical socket body 41 and a fitting groove 42 inclined from the front end surface to the rear end surface formed on the outer circumferential surface of the socket body 41. The reflector 2 is equipped with a socket fitting cylinder part 22 projecting from a reflecting surface 21 toward the rear; a fitting projection 23 projecting on the inner circumferential surface of the socket fitting cylinder part 22 in the inner diameter direction and to be fit to the fitting groove 42, and a blocking projection 24 for blocking the front end part of the fitting groove 42. The bulb socket 4 is supported to the reflector 2 by fitting of the fitting groove 42, the fitting projection 23, and the blocking projection 24. Since the front end part of the fitting groove 42 is blocked with the blocking projection 24, the cut out front end part of the fitting groove 42 is not exposed to the front side of the reflector 2 to enhance the outward appearance. Formation of a flange or a bayonet piece is unnecessary, increase in diameter of the bulb socket is prevented, and a small device is realized. |
