Claims

[Claims for Utility Model Registration] Sliding surfaces that come into contact with a fixed system due to elastic force, and thrust force in the axial direction generated by the driving force of the drive shaft to increase braking force based on the friction of the sliding surfaces. A brake member having a generated cam portion and an axial thrust force based on the braking force and the driving force of the drive shaft engage the clutch against the elastic member, and the drive shaft is released and the clutch is released from the hub. The drive gear is provided with a cam mechanism that releases the clutch connection based on the elastic force of the elastic member and the contact of the sliding surface when the clutch is rotated in a direction opposite to that when the brake member is connected, and the brake member is spline connected to the drive shaft. has an engaging cam that is driven by engaging with a brake release pawl provided at the clutch when the clutch is engaged, and when the engaging cam and the brake release pawl engage when the clutch is engaged, the elasticity of the sliding surface is reduced. A hub clutch that reduces sliding friction of a brake member, which is engaged through a tapered surface that generates thrust force in a direction that reduces friction caused by force.
