ABSTRACT:
A cylindrical member is formed integrally on a lamp housing and enclosing a threaded portion formed on the rear end of an aiming screw. First and second sliding members are disposed coaxially inside the cylindrical member around the threaded portion of the aiming screw. The first sliding member is slidable from first to second position in relation to the second sliding member. In the first or second position, the first and second sliding members are blocked from sliding relative to each other. The second sliding member has formed thereon an elastic flap having a stopper which is to be engaged in the cylindrical member when the first sliding member takes the first position. When the first sliding member is in the second position, the stopper is disengaged from the cylindrical member. Further, the second sliding member has formed thereon teeth which are engaged with the threaded portion upon disengagement. By turning the aiming screw, the first and second sliding members can be slid together in relation to the cylindrical member. Either of the first and second sliding members and the cylindrical member has formed thereon graduations and a reference-point mark, respectively, corresponding to the second position. The central one of the graduations coincides with the reference-point mark. The sliding distance of the first and second sliding members attained when the aiming screw is turned can be read from the relation between the graduations and reference-point mark and indicates the optical-axis adjustment of the tilting member.
