Claims

[Claims for Utility Model Registration] A housing that is fixed to a wheel hub with bolts and has a gear portion on its inner circumference, and a spring that biases the housing in the direction of disengaging the clutch from the gear portion when the drive shaft is driven. A friction sliding mechanism that includes a slide gear that is clutch-coupled with the housing against a mechanism, and a cam portion that engages with the first cam portion of the retainer to generate a thrust force, and that generates a braking force based on the thrust force. The first part with
a brake member, a second brake member that engages with the first brake member at the sliding portion and is rotationally fixed to the spindle at a peripheral portion in one direction; and a second brake member that is spline-coupled at the outer peripheral portion of the slide gear; a cam disposed to be movable in the axial direction against the spring mechanism; a second cam part that engages with the nuclear force l; and a first cam part that engages with the first brake member. and a thrust bearing disposed between an end surface of the retainer and a thrust receiving surface of the housing, wherein a race is provided between the axially outer end surface of the retainer and the thrust bearing. is arranged, the race is fixed to the retainer without contacting the housing, and
A hub lock comprising a flange portion for preventing eccentricity of the thrust bearing.
