Abstract
A remote control system for a vehicle mirror comprises a pair of drive systems each having a nonrotatable actuator shaft (12) caused to move longitudinally by an internally threaded bore (52) of a pinion gear (14) in driving engagement with a worm gear (16) on a shaft of a motion (18). The actuator shaft (12) is divided by a slot (36) into two end portions (38, 39). The first end portion (38) has a threaded protrusion (42) and the second end portion (39) has an unthreaded protrusion (44). Both end portions additionally spring biased (40). The actuator shaft (12) is made of flexible plastic so that the shaft flexes as the mirror pivots with respect to the motor housing (10).
