<p>PROBLEM TO BE SOLVED: To certainly conduct aiming adjusting in a vertical direction and a horizontal direction even if a reflector is thin. SOLUTION: A reflector 1 having a light source therein is displaced in relation to a housing 2, thereby adjusting illuminating light in vertical and horizontal directions. An aiming supporting shaft 3 becoming a fulcrum of the displacement and two aiming acting shafts 4, 5 becoming an acting point of the displacement are disposed at the apexes of a place triangle in the reflector 1. The aiming supporting shaft 3 is allowed to vertically move and rotate, and one aiming supporting shaft 4 is allowed to move in a back-and-forth direction while restricted in vertical moving, and the other aiming supporting shaft 5 is allowed to move in the back-and-forth direction and rotate.</p> |
