Claims

[Scope of utility model registration request]

A housing fixed to the outer end of the wheel hub, a drive gear engaged on the outer periphery of the drive shaft when the drive shaft is driven, and a spline engagement with the drive gear to connect the housing with the clutch portion of the housing. a slide gear that is coupled to the clutch portion of the housing against a spring mechanism that biases the clutch in the releasing direction; a second brake member that engages with the fixed spindle at its inner peripheral portion and is prevented from rotating; a first brake member that generates a braking force between the first brake member and the brake member; a cam that is spline-coupled on the outer circumferential portion of the slide gear and is disposed so as to be movable in the axial direction; and a first brake member that engages with the cam portion of the cam. In the hub lock, the hub lock includes a retainer having a protrusion that engages with the first cam portion and the first brake member, and the first brake member is an elastic brake having bent portions bent in the radial direction at both ends in the circumferential direction. The drive gear is provided with a pawl portion that deforms the first brake member in a compression direction when engaged with the bent portion of the first brake member;
A hub lock characterized in that the retainer is provided with a protrusion that deforms the first brake member in an expanding direction.
