PURPOSE: A synchronizer ring for a synchronizer is provided to prevent noise caused by colliding a key with a clutch hub by absorbing the movements of the synchronizer ring to the change of the angular acceleration of an engine with a spring installed in the key. CONSTITUTION: A synchronizer ring(50) for a synchronizer is composed of a groove unit(53) on which a key(60) is placed; a body(51) including threads at the inner peripheral surface; and a gear unit(52) integrated with the body and engaged to a sleeve with a clutch gear of a transmission. The key comprises a key body(61) of which one side is placed to the groove unit and the other side is protruded toward a clutch hub, including a projection at the upside; a spring installed in the protruded part of the key body; and two spring caps(63) protruded to the side of the key body through through-holes formed at both sides of the key body to protrude the spring and closely contacted in the groove of the clutch hub with supporting each end of the spring.
