Claims

[Claims for Utility Model Registration] A cylindrical body fixed to the outer end of a wheel hub rotatably assembled to the outer end of an axle tube, and an axle inserted into the axle tube within the cylindrical body. an inner sleeve fixed to the outer end protrusion so as to be capable of transmitting power; and a first member attached to the inner sleeve or the cylindrical body so as to be movable in the axial direction and capable of transmitting power and provided on the cylindrical body or the inner sleeve. a clutch having a second meshing tooth that removably engages with the meshing tooth; a cam follower that is rotatably assembled on the inner sleeve and resiliently contacts the cam surface of the cam; and a cam follower. A joint that connects the clutch in the axial direction, and a brake mechanism that is disposed between the axle tube and the cam and brakes the cam when the axle shaft is rotationally driven to generate relative rotation between the cam and the cam follower. In the auto freewheel hub, the clutch is moved in the axial direction via the cam follower by the operation of the cam surface of the cam when the axle shaft is rotationally driven, and the two meshing teeth are engaged and disengaged. The brake mechanism includes a cylindrical member fixed to the axle tube, a friction member fixed along the inner or outer periphery of the cylindrical member, and a spring member disposed in slidable contact with the friction member. , an auto freewheel hub O- characterized in that the spring member is brought into contact with a friction member by rotation of the cam.
