Headlamp for motor vehicles

摘要

A motor vehicle headlamp provided with a leveling gauge for determining whether or not the angle of irradiation of the light beam emitted by the headlamp is properly oriented in upward and downward directions which permits easy adjustment of the angle of irradiation of the headlamp beam. In the case of a movable reflector type headlamp, the headlamp is provided with a leveling gauge for measuring the amount of inclination of the irradiating angle of the headlamp in the upward and downward directions having a casing mounted on the upper wall area of the reflector in the front part of the headlamp unit in such a manner as to permit observation thereof through the exterior wall of the headlamp lens. One end part of the cover is supported elastically and held securely with an indented lance coupler formed in the juncture with the casing, while the other end part of the cover is held securely with a vertical screw threadedly engaged in the casing and is also supported elastically with a spring member installed between the cover and the casing.
