PROBLEM TO BE SOLVED: To enable a wedge bulb to be prevented from swinging by mounting an additional bulb holding fixture facilitating insertion and release near an inlet of a wedge base insert hole of a socket body and providing the socket body with a positioning part in close contact against the vicinity of a root of a mounted wedge base. SOLUTION: When a light source bulb of a single filament type wedge bulb 1 or a double filament type wedge bulb 2 is mounted to a socket 9 or 7, bulb holding fixtures 10 and 8 independent of a socket body are mounted near the inlet of a wedge base insert hole of the socket body. At a part opposed to wedge bases 1d and 2e of the bulb holding fixtures 10 and 8, a shape in which insertion and release of the wedge bases 1d and 2e is not prevented is formed. At the positions of the sockets 9 and 7 opposed to the vicinity of the root of the wedge bases 1d and 2e in their mounted state, positioning parts 9a, 7a, and 7b are provided so as to be in substantially close contact with the wedge bases 1d and 2e. |
