The present invention relates to a synchronizer ring. A shiftable transmission includes a synchronizer of a gearshift and the synchronizer ring is connected to a clutch gear. The synchronizer ring comprises: a center ring which is connected to the side of the clutch gear and of which the inner circumferential surface and the outer circumferential surface are respectively tapered; an inner ring having a first stage which is connected to the inner circumferential surface of the center ring and is tapered and a second stage which extends from the first stage in the axial direction; an outer ring which is connected to the outer circumference of the center ring and to which the second stage of the inner ring is connected to be restricted in such a way as to be able to rotate together with the inner ring; and an elastic member located between the outer ring and the inner ring to provide elasticity in such a manner that the outer ring can be separated from the inner ring, thereby preventing drag by unnecessary contact by generating clearance on a contact surface between the outer ring and the inner ring and reducing a risk of abrasion or damage. |
