ABSTRACT:
An adjusting mechanism for a headlamp or the like is provided with a molded gear housing having a gear-journaling bore and an apertured cap portion closing the outer end of the bore. A drive gear is rotatably journaled in the bore and is coupled to a drive shaft extending through the apertured end cap portion. A retainer member is mounted within the bore and engages the shaft and bears against the interior surface of the cap portion in order to prevent correspondingly uncoupling and retraction of the shaft end from the housing and the drive gear. The drive gear is rotatably meshed with an adjusting gear which is journaled with a second bore integrally molded in the gear housing. The second gear has a nut portion which is threaded to a linearly movable screw which produces the pivoting torque for adjusting realignment of the headlamp.
