Abstract
An outside mirror of a vehicle has an ultrasonic vibrator attached to its rear side for removing water and the like from the front side of the mirror. The mirror is attached to a frame by means of a supporting member extending around an outer peripheral edge of the mirror. The supporting portion is formed of a material having less acoustic impedance than the mirror. The vibrator has electrode connectors connected to wires from a control device by being mechanically clamped to those wires.
