Abstract: A rear view mirror assembly for a motor vehicle, includes a mirror holder for supporting a mirror body, an operating threaded shaft movable backward and forward along an approximate axial direction thereof in a mirror case, and a nut member connected with a driving device in the case. The holder is supported to be inclinable around a lateral and/or a vertical incline center axes with respect to the case. The head of the shaft is fitted in the fitting portion of the holder to be inclinable relative to the fitting portion. The screwed portion of the shaft is screwed in the nut member. The nut member has an annular projecting portion for sliding on a circumferential surface of the shaft. The specified portion of the shaft, which is positioned at the opposite side to the holder and away from the screwed portion, is penetrated through a through hole formed by the projecting portion to be movable backward and forward along the approximate axial direction of the shaft and inclinable therearound.
