PROBLEM TO BE SOLVED: To adjust an optical axis with high efficiency and high accuracy and reduce the number of part items. SOLUTION: Torque of a motor M is transmitted to an engaging tooth 132 and a movable reflector 13 through a pinion 72. and the movable reflector 13 is rotated in a vertical direction around a horizontal shaft member 71 in relation to a bracket 7 and a lamp housing 10. Since the rotation of the motor M is transmitted to the engaging tooth 132 and the movable reflector 13 through the rotation of the pinion 7, an optical axis can be adjusted efficiently and accurately, and since the pinion 72 is not displaced in association with the rotation of the movable reflector 13, a separate member for absorbing the displacement of the pinion 72 is dispensed with. |
