Abstract: A side view mirror assembly includes a casing inside which a reflector is mounted and a mount by which the casing and reflector are mounted to an automobile. The mount includes an outer frame member defining a triangular opening to receive a stack of first and second inner mount members. The first inner mount member has an outside surface on which two elongated slots are formed to each receive an L-shaped slide. Each L-shaped slides has a first section slidably received in the slot and a second section perpendicular to the first section and fixing an end of a helical spring of which an opposite end is fixed to the casing. The first section of the slide defines an inner-threaded hole. A bolt that extends through a hole defined in the second inner mount member and the slot of the first inner mount member is engageable with the inner-threaded hole of the slide. By tightening the bolt, the spring is elongated and inducing a force that securely retains the casing on the mount.
