Claims

[Scope of utility model registration request]

a case fixed to the wheel hub and having a spline on the inner periphery; a drive gear fixed to the outer periphery of the tip of the axle shaft and having a gear part on the outer periphery;
a cam member that is spline-engaged to the outer periphery of the drive gear so as to be movable in the axial direction and has a protruding cam portion on the axially inner side; and a cam member that is prevented from rotating by a fixing system and is engaged with the cam portion of the cam member. a brake outer having a groove-shaped cam portion and a friction surface; a groove-shaped brake outer having a brake surface that engages with the friction surface of the brake outer to generate a braking force and that engages with the protruding cam portion of the cam member; a cam ring having a first cam part, a second cam part continuous to both sides of the groove-shaped first cam part, and a stopper; and a cam ring fixed to the brake outer and capable of moving in the axial direction of the cam ring. a clutch ring that is slidably supported by a spline on the inner periphery of the case and is coupled to a gear portion on the outer periphery of the drive gear when displaced axially outward; and the cam member. and a step on the outer periphery of the drive gear to press the cam member inward in the axial direction; and a return spring that is in sliding contact with the outer surface of the cam member in the axial direction and the clutch ring. 1. A hub clutch comprising: a retainer that holds the clutch ring on an inner circumferential side; and a shift spring that is stretched between the retainer and the clutch ring and urges the clutch ring axially outward.
