Abstract
Abstract An automobile mirror device comprises a mirror mounted in a carrier which is connected by a universal joint to a base. A threaded spindle, driven by an electric motor, engages a split nut held by a spring steel stirrup pivotally connected to the carrier. When the mirror is tilted by rotation of the spindle to either of its end positions, the thread will disengage the nut by forcing apart the parts of the nut.
