Claims

[Scope of utility model registration request]

An axial thrust force is generated between a clutch actuation cam that moves the slide gear in the axial direction and the brake member based on the axial thrust force generated between the actuation cam and the brake member. In a hub lock equipped with a retainer having a braking cam that generates a braking force between the brake member and the fixed system, when the brake member is displaced in the axial direction due to wear, the retainer is arranged so that when the brake member is displaced in the axial direction due to wear, the displaced brake member and the brake A hub lock characterized in that a stopper is formed on the braking cam surface to prevent the cam from being disengaged from the braking cam.
