ABSTRACT:
The optical axis of the reflector is initially adjusted by operating the adjusting screw with the plate member held for a turning of the adjusting screw not to be transmitted to the plate member or with the ring member removed from the lamp housing for the turning of the adjusting screw not to be transmitted to the ring member. Therefore, after completion of the initial adjustment of the reflector optical axis, the index on the lamp housing can be easily put into coincidence with the reference point on the scale on the plate or ring member. Since the adjusting screw is isolated from the plate or ring member during the initial adjustment of the reflector optical axis, the optical axis of the reflector can be easily adjusted only by turning the adjusting screw. After completion of the initial optical-axis adjustment, the plate member is rendered to be slidable or the ring member is mounted to the lamp housing, thereby permitting to check how much the optical axis is to be readjusted, from a deviation between the index and the reference point on the scale.
