Abstract

A rear view mirror arrangement including a mirror housing mounted on the vehicle side door with face to face contact. The mirror housing is retained in a position laterally protruding from the vehicle side door by spring force provided by a spring positioned between the mirror housing and the vehicle side door. The spring force permits the mirror housing to temporarily displace from the vehicle side door in response to an impact applied to the mirror housing in order to absorb the impact. The mirror arrangement has a mirror angle adjustment lever capable of adjusting the mirror angle in both vertical and horizontal directions. The mirror angle adjustment lever is releasably connected to the mirror permitting the displacement of the mirror housing with respect to the vehicle side door when the impact is received by the mirror housing.
