Claims

[Claims for Utility Model Registration] A housing fixed to a wheel hub, a drive gear splined to the outer periphery of the tip of the drive shaft, and a housing disposed movably in the axial direction on the outer periphery of the drive gear and arranged axially inwardly. A cam having a protruding cam protrusion, an outer brake whose rotation is suppressed by a fixed member, and a cam disposed on the inner diameter side of the outer brake to generate a braking force between the outer brake and the cam. an inner brake that engages with the cam protrusion of the drive gear; a slide gear that is circumferentially locked to the outer periphery of the drive gear and supported so as to be freely movable in the axial direction, and that is clutched to the case when displaced axially outward; A hub clutch having a shift spring that is wound around the outer circumference of a gear and urges the slide gear in the axial direction, wherein one end of the shift spring is bent to form a bent part; A hub clutch characterized in that the bent portion is locked onto the slide gear on an extension line parallel to the axial direction of a portion of the cam where the cam protrusion is located.
