A rear view safety mirror is provided with an aperture through the mirror element through which extends a drive shaft for a wiper blade; the drive shaft is connected to the rotary armature of an electric motor which is mounted on the support bracket of the mirror in the rear portion thereof; the armature of the electric motor is mounted so as to be axially movable so that when the motor is supplied with direct current, the armature will shift its position to press the wiper element against the surface of the mirror during rotation thereof; a heating element is also provided in the housing of the mirror to maintain the mirror's surface free of ice and snow during inclement weather. |
