An automotive vehicle rearview mirror assembly comprising a plastic mirror holding member and a plastic support member provided with cooperating integral connecting structures providing for relative pivotal movements about two perpendicular intersecting axes. The connecting structures having a snap-in relation providing large interengaging dual parallel truncated spherical surfaces and smaller interengaging segmental spherical surfaces all having a common centerpoint. The support member connects with a cooperating casing member to form a casing assembly carrying a remotely controlled power operated mechanism for effecting pivotal movements of the mirror holding member. A sensing mechanism is also carried within the casing assembly for enabling the power operated mechanism to be automatically controlled as well as manually controlled. The power operated mechanism includes actuator assemblies each having a pair of actuator members one of which has a snap-in ball and socket connection with the casing member and a lug and notch connection with an associated pinion member. The sensing mechanism includes integral wall portions on the casing member for mounting two spaced sensing members with electrical contacts in cooperating relation with two potentiometer circuits on a single electrical circuit board.
