Claims

[Claims for Utility Model Registration] Based on the axial thrust force generated between the slide gear and the clutch operating cam that moves the slide gear in the axial direction, an axial thrust force is generated between the brake member and the In a hub/clutch equipped with a retainer having a braking cam that generates a braking force between a brake member and a fixed system, the retainer retains the displaced brake member when the brake member is displaced in the axial direction due to wear. A hub clutch characterized in that a cam surface of the braking cam that engages with the brake cam is provided with a cam angle that decreases in accordance with the amount of displacement of the cam surface.
