Unidirectional coupling-clutch runner

Unidirectional coupling-clutch runner comprising a coaxial pinion (1) and wheel (6) which pivot relative to one another, characterized by the fact that it comprises a first driving part (14) that is angularly integral with the pinion (1) comprising at least one elastic catch (15) with the general shape, in plan view, of a C, one branch of which is elongated and terminates with a free end;

• that it also comprises a second driving part (17) that is angularly integral with the wheel (6) and that is coplanar with the first driving part (14) comprising an internal wolf-toothing (16);
• and by the fact that in the neutral rest position the first and second driving parts (14, 17) do not touch one another, the end of the elastic catches (15) in the rest position which are not elastically deformed being located on a circumference (a) whose diameter is larger than a circumference which goes through the top of the wolf-teeth (16) and smaller than a circumference going through the bottom of the teeth (16) of the second driving part.
