Between the nut member and the part associated with the nut member there are provided two rings concentric to the spindle axis, each of said rings being supported to be radially displaceable upon a surface perpendicular to the spindle axis and extending into a substantially ring-shaped groove and hydraulically held in axial direction. Between the grooves and the ring members there is present sufficient play for inclinedly positioning the ring members in the grooves and the aforementioned surfaces are directed in opposite directions from one another.
