  • the first Nussteil 29 is connected to a second Nussteil 30, which has a square pin for attaching a door handle, via a toothed engagement 33, 34.
  • the tooth engagement is formed by teeth 33 extending in the axial direction of the two nut parts 29, 30.
  • the teeth 33 engage in tooth gaps 34, wherein both the tooth spaces 34 and the teeth 33 have circumferentially extending bevels.
  • the Nussteil 29 has a radially projecting collar 29 ', on which a coupling rocker 28 is supported. One end 28 'of the coupling rocker 28 is supported on a closure plate 32. The second end 28 "of the coupling rocker 28 cooperates with a switching element 26, which is designed as a slide, and a compression spring 27 is provided which holds the axially displaceable socket part 29 in the coupling position via a pressure on the coupling rocker 28.
  • the Nussteil 30 By means of a leg spring 31, the Nussteil 30 will be held in a middle neutral position, from which it can be rotated by turning the pusher.

  • the adjustment of the switching element 26 is effected by means of a switching member 19.
  • the switching member 19 is rotated by an electric motor 5, as in the previous embodiments, between two stop positions by 180 °.
  • the switching member 19 carries a first magnet 7, which forms a switching magnet.
  • the switching member 19 carries a compensation magnet 18, which, based on the first magnet 7, has an opposite polar direction.
  • both magnets 7, 18 are equally strong within the tolerances, so that the magnetic fields generated by them in the distance substantially cancel each other out.
  • the switching magnet 7 thus lies between one of two drive magnets 12, 12 'defined axis.
  • the switching member 19 has a rotational position in which the first magnet 7 is in attractive interaction with the drive magnet 12 '.
  • the other drive magnet 12 is repelled by the first magnet 7.
  • the end 28 "of the coupling rocker 28 lies underneath the blocking shoulder 26 'of the closing member 26 and can not yield, as a result of which the toothed engagement 33, 34 is retained even when a torque is applied by the nut part 30 to the nut part 29.
