Claims

[Scope of utility model registration request]

A clutch hub mounted on a rotating shaft so as to be rotatable therewith, a sleeve mounted on the outer periphery of the clutch hub so as to be rotatable and movable in the axial direction and having a tapered cone portion on the inner periphery side, this sleeve and the clutch hub. Between the gear spline parts of the gear rotatably assembled on one side, the spline part is assembled so as to be relatively rotatable and axially movable by a predetermined amount, and facing the tapered cone part of the sleeve on the outer peripheral side. A synchronizer ring has a tapered cone portion that engages and disengages from the tapered cone portion as the sleeve moves in the axial direction, and an engaged portion provided between the gear spline portion and the synchronizer ring and provided on the inner circumferential side of the ring receives elastic force. In the synchronizer, the synchronizer is equipped with a flexible leaf spring-like shifting key spring on the inside and outside of the diameter, and has an engaging portion that engages with the ring to restrict the movement of the ring in the axial direction with a predetermined force. A second engaged part is provided on the inner peripheral side of the synchronizer ring on one side in the circumferential direction of the engaged part, and a second engaged part is provided on the inner peripheral side of the synchronizer ring on one side in the circumferential direction of the engaging part. A synchronizing device comprising a second engaging portion that engages with a second engaged portion to position the synchronizer ring in the axial direction in a neutral state.
