Vehicular headlamp having a tilt measuring device

摘要

An automotive headlamp having a tilt measuring device for measuring an amount of horizontal tilt of a reflector is mounted between an aiming screw and a guide member extending parallel to the aiming screw. The aiming screw is supported by a lamp body. By turning (or moving back and forth) the aiming screw, the reflector is tilted in the horizontal direction. The tilt measuring device includes a slide member loosely coupled to the aiming screw and slidable along a guide member, a screw holding member functioning such that when the screw holding member grasps the aiming screw in proximity to the slide member, the sliding motion of the slide member is associated with the rotation (or the back and forth movement) of the aiming screw, and when the screw holding member is retracted to the side of the aiming screw, the coupling of the slide member with the aiming screw is released, a cursor provided on the slide member, and a scale provided on the guide member.
