Claims

[Scope of utility model registration request]

A clutch hub is attached to one side of the gear rotatably attached to the rotary shaft so that it can rotate integrally therewith, and a clutch hub is attached to the outer periphery of the clutch hub so that it can rotate integrally and move in the axial direction. A sleeve having a tapered cone portion on the inner circumferential side, and a tapered cone portion of the sleeve on the outer circumferential side, which is attached to the spline portion between the sleeve and the gear spline portion of the gear so as to be relatively rotatable by a predetermined amount and movable in the axial direction. In a synchronizer ring equipped with a synchronizer ring having a taper cone part that is engaged with and disengaged from the taper cone part by axial movement of the sleeve facing the gear spline part, the synchronizer ring is assembled into an annular groove provided on the inner periphery of the gear spline part. an annular spring whose diameter can be reduced and exposed through notched grooves provided at equal intervals in the circumferential direction in the gear spline part; and the synchronizer is supported so as to be movable radially inwardly and outwardly by the springs in each notched groove of the gear spline part. A plurality of key members elastically abut against the inner peripheral side of the ring to restrict the axial movement of the ring with a predetermined force and move radially inward when the ring rides on the ring, and a gear spline portion. A synchronizing device characterized by comprising a ring member that is fitted into a groove provided on the outer periphery of the leading end and abuts or approaches the clutch hub-side inner end surface of each of the key members.
