Abstract
The present invention relates to a power pack for an exterior automotive mirror assembly having a central depression in its upper housing whereby a large diameter pivot cup can be used. The drive motors are arranged within the power pack housing such that the central depression partially extends below the top plane of the motors and an overall low profile for the power pack is maintained. The pivot cup, of this power pack, is separate from the mirror casing and is retained by a unique spring retainer.
