PURPOSE:To prevent the interference of an elastic annular member and sleeve splines, by providing projections on the elastic annular member fitted on the inner circumferential portion of the rim of a clutch hub, and by engaging the projections with notches provided at circumferential intervals on the rim and extending in the axial direction of the hub. CONSTITUTION:An elastic annular member 7 is fitted on the inner circumferential portion of the rim 2a of a clutch hub 2. The boss 5c of a blocking ring 5 is inserted into the rib 2a so that the end face of the boss 5c is in contact with the annular member 7. Axially extending notches 8 are provided at three circumferential intervals on the rim 2a and correspond to cam portions 6. The annular member 7 is provided with three projections 7a at circumferential intervals and put in the notches 8. The annular member 7 is thus engaged at the projections 7a with the cam portions 6. |
