An apparatus for converting a rotational movement into an axial movement. A threaded rod is provided, on which a nut is arranged to be movable axially to the threaded rod. At least one blocking structure is provided, which is so arranged that it blocks rotational movement of the nut during the axial movement along the threaded rod. There is provided on the threaded rod at least one end stop, which limits axial movement of the nut along the threaded rod. Between the axially movable nut and the end stop, a wedge lock washer pair is arranged. The wedge lock washer pair is so embodied that the wedge lock washers are brought into engagement by the pressing of the nut against the end stop and produce a prestress torque, wherein torque for releasing the nut from the end stop is smaller, essentially by the prestress torque of the wedge lock washer pair, than the torque applied as the nut first pressed against the end stop. |
