Claims

[Scope of utility model registration request]

A cylindrical body fixed to the outer end of a wheel hub rotatably assembled on the outer end of an axle tube, and a power source mounted on the outer end protrusion of the axle inserted into the axle tube inside this body. An inner sleeve that is fixed in a transmissible manner, and an outer spline that is movably assembled in the axial direction between the outer periphery of the inner sleeve and the inner periphery of the body, and that the outer spline is permanently or detachably engaged with a spline provided on the inner periphery of the body. a clutch ring that meshes with the splines provided on the outer periphery of the inner sleeve, and an inner boss that is rotatably assembled via a cap fixed to the outer end opening of the body; a handle that faces the outer end of the inner sleeve inside the body, and a handle that is interposed between the inner boss portion of the handle and the clutch puffer, one end of which abuts against a cam surface provided on the inner boss portion, and a cam follower that moves in the axial direction by the action of the cam surface when a handle is rotated; a spring that is interposed inside the body and biases the cam follower directly or indirectly toward the clutch ring; and the clutch ring. In the freewheel hub device, the freewheel hub device includes a connecting member that connects the cam follower and the cam follower in the axial direction. A freewheel hub device characterized by being provided with a recess into which the hook is fitted and secured.
