Abstract
An exterior rearview mirror for a motor vehicle has a housing mounted on a base member by means of a ball-and-socket joint comprising a socket formed in the base member and a convex member attached to the housing. The socket comprises the concave inner surface of a hollow part-spherical member. An arm has a concave surface formed on one end and adapted to engage with the convex outer surface of the part-spherical member. Resilient means are arranged to bias the arm towards the convex member so as to urge the concave surface on the arm against the convex outer surface of the part-spherical member and to urge the concave inner surface of the part-spherical member against the convex member, and release means on the other end of the arm are operable to reduce the friction resisting movement of the housing relative to the base member about the part-spherical member. Operation of the release means thus enables the orientation of the housing relative to the base member to be adjusted with relatively little effort.
