Claims

[Claim for Utility Model Registration] A housing fixed to a wheel hub with bolts and having a clutch portion on the inner periphery, and a spline engagement with a drive gear that is engaged on the outer periphery of the drive shaft when the drive shaft is driven. a slide gear that engages with the clutch of the housing against a spring mechanism that is driven in a direction to disengage the clutch of the housing; a second brake member whose rotation is inhibited; and a first brake member of the retainer.
a first brake member having a cam portion that generates a thrust force by engaging with a cam portion of the first brake member, and generating a braking force between the first brake member and the second brake member based on the thrust force; and an outer periphery of the slide gear. A cam that is connected to a spout and a line at a portion thereof and is arranged 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. In the hub lock equipped with a retainer, a protruding portion is formed to extend on the axially outer side of the drive gear, and the clutch portion of the housing has an engaging portion on the axially inner side;
What is claimed is: 1. A hub lock comprising: bearing support portions on the outside in the axial direction; and a rolling bearing disposed between the outer protruding portion of the drive gear and the bearing support portion of the housing.
