In an automobile headlamp, a light source unit in a lamp body is inclined vertically and horizontally with an aiming mechanism, the rotating operation sections of a vertical aiming screw and a horizontal aiming screw which form the aiming mechanism are provided outside of the lamp body, and the rotating operation sections are turned to incline the light source unit vertically and horizontally. In the automobile headlamp, a protruding wall is extended at least at the horizontal aiming screw in such a manner as to surround the rotating operation section of the horizontal aiming screw, and a part of the protruding wall extending end portion is integrated through a thin hinge with a lid, namely, a tongue-shaped plate in such a manner that the latter is extended in the same direction as the protruding wall. As for a specification that requires no horizontal aiming operation, the tongue-shaped plate is folded along the thin hinge and locked in such a manner as to close the opening of the protruding wall, to close the rotating operation section in the protruding wall with the tongue-shaped plate, thereby to make it impossible to perform the horizontal aiming operation.
