ABSTRACT OF DISCLOSURE An electrically powered remotely controlled rearview mirror comprises a pair of mirror-engaging position-adjusting non-rotatable screw shafts, each caused to move longitudinally by a rotatable ball nut received within a spherically socketed annular pinion gear which is rotatably driven by a worm gear on the output shaft of the motor. The ball and socket connection between the ball nut and pinion gear permit the axes of the nut and screw shaft to skew relative to that of the pinion gear. A pair of splines on the interior of the pinion gear engage slots on the spherical surface of the ball nut to establish a driving relationship for simultaneous rotation when the associated motor is actuated. -10-
