Claims

[Claims 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 knob for manual operation that has a boss part with a cam surface that slopes from the inside to the outside, a drive gear that is fixed to the outer periphery of the tip of the axle shaft and has a gear part on the outer periphery, and an axially arranged knob on the outer periphery of the drive gear. a cam member that is movably engaged with a spline and has a protruding cam portion on an axially inner portion and a projecting portion on an axially outer inner diameter portion;
a brake outer that is prevented from rotating by a fixed system and has a grooved cam portion and a friction surface that engages with the cam portion; and a brake surface that engages with the friction surface of the brake outer to generate braking force. and a cam ring having a groove-shaped first cam portion that engages with a protruding cam brake of the cam member, and a second cam portion continuous to both sides of the groove-shaped first cam portion; a clutch ring that is slidably supported by a spline on the inner circumference of the case and is coupled to a gear portion on the outer circumference of the drive gear when displaced axially outward; and a protrusion of the cam member and a step on the outer circumference of the drive gear. a return spring that is tensioned between the cam member and the cam member and presses the cam member inward in the axial direction; and a return spring that is in sliding contact with the axially outer surface of the cam member and is engageable with the cam surface of the knob. It consists of a retainer having a claw portion, and a shift spring that is stretched between the retainer and the clutch ring and presses the retainer against the cam member, and is engaged with at least either the cam member or the cam ring. A hub clutch characterized by having a pawl portion.
