Claims

[Scope of Claim for Utility Model Registration] A housing fixed to a wheel hub, a drive gear spline-coupled to the outer periphery of the tip of a drive shaft, a cam member disposed movably in the axial direction on the outer periphery of the drive gear, and fixed. A braking force is generated between a first brake member whose rotation is suppressed by a system member and the first brake member disposed on the inner diameter side of the first brake member, and the cam member a second brake member that engages with the outer circumference of the drive gear or the inner circumference of the housing in the circumferential direction and is supported so as to be freely movable in the axial direction, and when displaced axially outward, the second brake member engages with the outer circumference of the drive gear or the inner circumference of the housing; In the hub clutch, the second brake member has three locations on its outer periphery that contact the first brake member. A hub clutch characterized by a protrusion.
