Wiper for outside mirror including a string for wiping

摘要

A wiper for an outside mirror including a mirror housing supporting tiltably a mirror holder to which a mirror proper is fixed, comprising an endless circumferentially moving belt so disposed generally along the circumference of the mirror proper as not to overlie the reflecting surface of the mirror proper, a plurality of pulleys so disposed as to have the circumferentially moving belt threaded thereon, and a string disposed along the reflecting surface of the mirror proper and which is connected at one end thereof to the circumferentially moving belt and at the other end to a tensioner which imparts a tension to the spring. When one of the pulleys is rotated, the circumferentially moving belt is rotated, the tensed string slides in contact with the mirror surface to wipe the latter.
