Abstract
A power antenna actuator mechanism has a worm and gear drive for a cable storage drum which is integral with the worm gear. A covering, which cooperates with a housing to enclose the actuator mechanism, has a rib portion which abuts a circumferential surface of the storage drum for an arcuate distance adjacent the mesh point of the worm and worm gear to provide a support member for the storage drum in a radial direction transverse to the axis of the worm.
