ABSTRACT:
An outer rear view mirror for a vehicle includes a casing for being connected to a side portion of the vehicle, a mirror member having an outer surface and accommodated within the casing such that the outer surface extends substantially perpendicular to a road surface, and a generator positioned at an upper portion of the outer surface of the mirror member and generating surface acoustic waves which travel along the outer surface of the mirror member towards a lower portion thereof. Water drops on the outer surface of the mirror member are expected to be urged to the lower portion of the mirror member, which results in that the resultant water drops are expelled by the gravity. Thus, the water drops can be removed from the outer surface of the mirror member.
