A rear view mirror for a motor vehicle in which a mirror head is mounted for angular movement about two axes at right angles to each other and is adjustable about these axes by rotation of a single control shaft. Adjustment of the head about one axis is effected by rotation of an eccentric element by the shaft, and adjustment about the other axis is effected by linear movement produced by rotation of a second element such as a scroll cam or screw thread. A lost motion device is arranged between the shaft and at least one of the elements so that a degree of adjustment of the mirror head about one axis can be effected without alteration to the angular setting of the head with respect to the other axis. The lost motion device may be arranged between the two elements or between an additional fine-adjust device and both the elements. |
