  • the coupling member 14 is slidably disposed relative to the shaft 3, wherein the bore 14 is aligned in the radial direction of the shaft 3.
  • the bore 14 in the embodiment according to the 8 to 11 corresponding to the bore 14 in the embodiment according to the Fig. 4 to 7 formed so that the bore 14 of the embodiment according to the Fig. 8 until 11 a contact shoulder 45, on which the coupling member 41 comes into abutment in the decoupled position. It should be noted that unlike the design according to the Fig. 4 to 7 Here, the coupling member 41 in the bore 14 and in the embodiment according to the Fig. 4 to 7 in the bore 40 of the locking lug 5 is guided.
  • the coupling member 41 has an end facing the rolling element 46 in the form of a profiled end face 47.
  • the end face 47 is subdivided into a receptacle 48 modeled after the outer circumference of the rolling element 46 and a projection 49.
  • the bore 14 in the shaft 3 is formed with an extension 50 at its end facing the outer circumferential surface of the shaft 3, which as well as the receptacle 48 is essentially the outer contour of the rolling element 46 is partially replicated.
  • the projection 49 prevents the rolling element 46 in uncoupled, in Fig. 9 shown state penetrates too far into the bore 14 and leads to a locking between the shaft 3 and the further shaft 17.
  • the coupled state is shown schematically. It can be seen that the coupling member 41 is moved in the direction of the locking lug 5 of the further shaft 17, so that the surface of the receptacle 48 together with the surface of the extension 50 as a whole forms a receptacle for the rolling element 46.
  • the projection 49 engages in the in Fig. 11 shown coupled state slightly into the bore 40 and prevents the rolling element 46 is displaced in a rotational movement of the shaft 3 in the bore 40 against the compression spring 42.
