A hinge actuator for a wing mirror of motor vehicle, which is operative between an extreme fold-in position and an extreme fold-out position and between the extreme fold-out position and an extreme fold-over position, comprising a mirror base, provided with a frame with a frame part which extends around a base shaft and supported on a base flange. A first cam track located between the base shaft and the frame part, with at least one bearing element, is present, and a first elastic element extending on a side along this track. During a rotation of the frame relative to the base shaft between the extreme fold-in position and the extreme fold-out position, the first elastic element contact with the bearing element undergoes a deformation, while during a rotation between the extreme fold-out position and the extreme fold-over position, the first elastic element undergoes a further-going deformation.
