ABSTRACT:
In an optical-axis adjusting apparatus for use with automotive lights, an adjusting member is provided to orientate the lamp unit by tilting the latter about the horizontal and vertical axes. The adjusting member includes an adjusting threaded rod screwed in an internally threaded member fixed to the body of motor vehicle and which can be moved forwardly and reversely. The shank of the adjusting threaded rod has formed a ball-shaped portion at a part thereof. The ball portion is received in spherical concavities of the holder and rotatably supported in the holder. The holder is elastically fitted in a holder support member from a direction substantially perpendicular to the forwardly and reversely moving direction of the threaded rod and prevented from coming off the holder by means of stoppers. Therefore, the adjusting member can be easily and securely installed to the lamp unit and permits a smooth optical-axis adjustment.
