PROBLEM TO BE SOLVED: To provide a reflector fixture which facilitates fixing work, reduces quality dispersion due to the fixing work, and gives high reliability after the fixing work. SOLUTION: A reflector fixture 12 consists of an opening at the center of a contact part 12a, pawls 12d for a magnet and a stopper part 12e for the magnet, and is further provided with a part for housing a magnet 10, a pawl 12b for the reflector having the shape of a leaf spring and formed projectingly from the peripheral part of the contact part 12a and a stopper part 12c for the reflector. The pawl 12b for the reflector of the reflector fixture 12 and the stopper part 12c for the reflector are inserted into the gap between the frame part 6a of a plate 6 and the base part 6b until the contact part 12a comes in contact with the base part 6b from the opposite side of the reflector 8 across the base part 6b, and the tip part of the pawl 12b for the reflector abuts on the reflection plane of the reflector 8. Thus the reflector 8 and the magnet 10 are integrated with base part 6b by the elastic force of the reflector fixture 12 without using an adhesive or a double-stick tape.
