Claims

[Scope of utility model registration request]

An inner clutch is spline-coupled to the axle shaft, and splines are formed on both the inner and outer circumferential surfaces of the inner clutch so as to engage with splines formed on the outer circumferential surface of the inner clutch and the inner circumferential surface of the body, respectively, and the inner clutch is movable in the axial direction. A ring-shaped outer clutch arranged, a follower having one end abutting the outer clutch and engaging with a spline of the body so as to be movable in the axial direction, and a radial claw portion formed at the other end, and a claw portion of the follower. a handle that is rotatable relative to the body and whose axial movement is restricted and that can be engaged with a cam surface to set the body and the inner clutch in an engaged or released position; and a handle that urges the follower toward the outer clutch. and a tension spring that biases the outer clutch and the follower in a direction to connect them in order to integrally connect them. The holder, which is a member, is arranged such that the tip of the cylindrical portion faces the spline end surface of the outer circumferential surface of the outer clutch, and the inner circumferential end surface of the bottom portion contacts the outer circumferential surface of the tip boss portion of the handle. wheel hub.
