In order to produce an alternating angular position in the case of a rotating axle, the longitudinal axle (7) is supported via needle bearings (12) in the housing (1) such that it can be displaced axially, and is elastically adjustable at the other end. An operating shaft (35) runs transversely through the housing (1), transversely with respect to the longitudinal axle (7), and has a fork to which one of the projections of a nut on the thread of the longitudinal axle can be coupled, so that the straight-line displacement movement of the nut can be reversed during angular rotation of the fork and of the associated operating shaft; the rotation movements can in each case be set on both sides by means of correspondingly adjustable stops. The electric motor (4) which is used for operation can be stopped and reversed by means of microswitches (23) which can be operated via a rod (51) parallel to the motor shaft (15).
