FIELD: machine building.

SUBSTANCE: driven half-clutch (4) has cams (8) in form of cylinder sectors. Cams (8) have tangential blind orifices (10) wherein there are inserted cylinder springs (11) of compression. Also, driven half-clutch (4) functions as a sliding support for holder (9) of ratchets (12) which has internal slots corresponding to cams (8).
