Claims

[Scope of Claim for Utility Model Registration] A cylindrical case fixed to a wheel hub and having a spline on the inner periphery and an opening on the outer end surface; a manual operation knob having a boss portion formed with a cam surface that slopes from the inside to the outside; a drive gear fixed to the outer periphery of the tip of the axle shaft and having a spline 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. an outer brake having a groove-shaped cam portion and a friction surface; a groove-shaped outer brake having a brake surface that engages with the friction surface of the outer brake to generate a braking force and that engages with the protruding cam portion of the cam member; a cam ring having a first cam portion and a second cam portion connected to both sides of the groove-shaped first cam portion; a clutch ring that engages with a spline on the outer periphery of the drive gear when the cam member is displaced; and a return spring that is stretched between the cam member and a stepped portion on the outer periphery of the drive gear and presses the cam member inward in the axial direction. a retainer having a claw portion that is in sliding contact with the axially outer surface of the cam member and is engageable with the cam surface of the knob; and a retainer that is stretched between the retainer and the clutch ring. a shift spring that presses the retainer against the cam member; a check protrusion protrudes from the axially outer end of the cam surface of the knob; 1. A hub clutch characterized in that a check cam portion is formed that locks the check protrusion when the hub clutch is set to the hub clutch.
