Claims

[Claims for Utility Model Registration] A housing fixed to a wheel hub, a drive gear rotationally locked to a drive shaft, and a cam portion disposed on the outer periphery of the drive gear so as to be movable in the axial direction. a cam that moves in the axial direction in conjunction with the axial movement of the cam, and a slide gear that clutches the housing and the drive gear; and a first brake that is prevented from rotating by a fixed member. a second brake that engages with the first brake to generate a braking force with the first brake and has a cam portion; the cam portion of the second brake and the cam portions that respectively engage with the cam portions of the cam;
A hub clutch having a retainer for axially moving the cam, wherein the retainer is disposed on the outer periphery of the drive shaft so as to be restricted from moving toward the cam via rolling elements. Hub Clutch.
