するオートフリーホイールハブ。 Disposed between a wheel hub rotatably assembled to the outer end of an axle tube and the outer end of an axle rotatably inserted through the axle tube, the wheel hub is rotatable integrally with the axle or wheel hub and is axially rotatable. a clutch that is movably assembled to the wheel and engages and disengages from the wheel hub side or the axle side when moving in the axial direction; a cam that is rotatably assembled to the axle side; and a cam that is rotatably assembled to the axle side; A cam follower is attached to the axle side so as to be integrally rotatable and movable in the axial direction and is axially connected to the clutch, and the cam follower is interposed between the cam follower and the axle side and is biased to activate the cam. A spring member elastically brought into contact with the cam surface, and a brake mechanism disposed between the axle tube and the cam to brake the cam when the axle shaft rotates to generate relative rotation between the cam follower and the cam follower. In the auto freewheel hub, as the spring member,
An auto freewheel hub characterized by employing a shape memory alloy spring member that deforms at a predetermined transformation point to change the mounting load.
