Abstract
A synchronizer of a transmission may include bottom key disposed on a hub to be slidable in a radial direction of the hub; a top key disposed radially outside the bottom key to be slidable in an axial direction of the hub; a sleeve disposed outside the hub and sliding in the axial direction to slide the top key in the axial direction to press a synchro-ring; a key spring disposed between the bottom key and the hub to press the bottom key and the top key toward an internal side of the sleeve; and a motion converting portion converting relative motion generated in a circumferential direction of the hub between the top key and the bottom key into axial relative motion of the top key to the bottom key toward the synchro-ring.
