Abstract

Abstract In an external rear view mirror a cupped housing has an open side in which a mirror member is retained, with an annular sealing ring being interposed between the mirror member and the housing. The sealing ring has a main annular body portion and an axially adjacent annular sealing lip extending along the main annular body portion with both of them together having a circumferential edge face provided with a plurality of circumferentially distributed at least substantially radial kerfs which extend through the radial thickness of the sealing lip but only partly through the radial thickness of the main body portion.
