PURPOSE: To keep excellent visibility of the front door glass by removing the rain drop on the front door glass of a vehicle.

CONSTITUTION: In this device, a driving mechanism of a wiper is incorporated in a rear-view mirror body frame, and the rain drop on the front door glass is removed. The driving mechanism of the wiper is structured so that the wiper wipes the glass surface by snapping a wiper retainer 9 pulled by a spring 7 by a crank 6 provided in a motor 5. In the wiper retainer 9, a copying plate copies the angle of the glass, and the wiper is deviated neither to the inner side nor to the outer side of the contact surface of the glass. A rotary wheel 8 is used for the wiper to execute copying. All operations are remotely and manually controlled. The operational speed of the wiper is variable.
