A rotor (13) with bearings turning on an axle (14) forms an adjusting element that can be displaced into a rotating motion by wires (2,3). A radial guide (10) holds a holding part (11) that is pressed onto the rotor as a wire contracts and holds the rotor in position, as long as a catch (7) is raised. This prevents an unexpected turn of the rotor on the axle.
