ABSTRACT:
An optical axis adjusting device for automotive headlights is disclosed which consists of a pair of optical axis adjusters provided between the lamp unit and car body and each composed of an adjusting screw and screw mounting to adjust the optical axis of the lamp unit with the lamp unit tilted horizontally or vertically with respect to the car body by turning the adjusting screw. Each of the screw mountings is protruded at one end thereof to the back of the car body while the other end thereof is protruded to the front of the lamp unit. The adjusting screw is protruded at one end thereof to inside the car body and at the other end thereof to the front of the headlight, and has a first head formed at the one end thereof and a second head provided on the other end thereof. By turning an adjusting tool fitted on either the first or second screw head, the optical axis of the headlight can be adjusted at either of the front and back of the headlight. The second screw head has a stopper which is to abut a first abutment formed on the screw unit and prevent the adjusting screw from coming off from the screw mounting when the adjusting screw is excessively turned at the first head thereof in a direction to move the screw mounting toward the front of the headlight. The lamp unit or screw mounting has formed thereon a second abutment which the adjusting tool abuts and works to disengage the adjusting tool from on the second screw head when the screw mounting is moved to a predetermined position during adjustment of the optical axis at the second screw head.
