る。(Effect of the Invention) According to the lighting fixture of the present invention, in a state where the base of the discharge lamp is connected to the socket, the overlapping portion of the top plate portion of the reflector overlaps the upper side of the base of the discharge lamp, and temporarily assumes that Even if the removable reflector is displaced downward, the overlapping part of the top plate of the reflector is caught on the base of the discharge lamp to prevent it from dropping. Thus, the number of parts and the number of assembly steps can be reduced.
