Claims

[Claims for Utility Model Registration] A housing fixed to a wheel hub with bolts and having a gear portion on its inner periphery, and a spring that biases the housing in the direction of disengaging the gear portion of the housing when the drive shaft is driven. a slide gear that clutches with the housing against a mechanism;
A second brake member that engages with the stationary spindle at the inner circumferential portion to prevent rotation, and a cam portion that engages with the first cam portion of the retainer to generate a thrust force. a first brake member that generates a braking force between the first brake member and the second brake member based on the first brake member; A retainer having a cam that is spline-coupled to the outer circumference of the slide gear so as to be movable in the axial direction, a second cam portion that engages with the cam, and a first cam portion that engages with the first brake member. A hub lock, characterized in that the lock nut directly engages with the second brake member and is prevented from rotating by the second brake member.
