A wiper for an automobile rear-view mirror includes a wiper transmission device disposed at the rear side of a mirror base, a connecting rod and a wiper. The wiper transmission device has a transmission motor provided with a drive gear engaged with a driven gear coupled with a worm that is engaged with a worm gear. The worm gear is connected with a driven worm by a support shaft, and the driven worm is engaged with a driven worm gear secured on a rotating shaft, which has its outer end inserted out of the rearview mirror and fixed with a connecting rod having a wiper fixed thereon. When the wiper transmission device is started, the wiper can sway upward and downward for wiping water drops off the surface of the rear-view mirror to keep it clear, enabling a driver to clearly watch the traffic conditions and drive safely.
