Abstract

To avoid wind noises and to reduce soiling of mirror glass during travel in the rain, the exterior rear view mirror for a motor vehicle has a droplet channel in a first circumferential region of the mirror housing that includes the housing top and a separation edge in a second circumferential region on the housing bottom. The droplet channel and the separation edge overlap in a lateral region. Rain droplets that strike the mirror housing during travel flow both on the bottom housing side and on the top housing side toward the rear edge of the housing. Water droplets flowing on the bottom are collected by the separation edge and are blown away by the air flow which is directed down at the separation edge. On the housing top side, the droplets are collected by the droplet channel and conducted away laterally toward the housing bottom.
