摘要： A transmission synchronizer includes a lower key that is installed to be slidable with respect to a hub in a radial direction of the hub and an upper key that is installed on an exterior of the lower key, the upper key being slidable in an axial direction of the hub. Additionally, a sleeve is installed at an exterior of the hub to slide the upper key in the axial direction while the sleeve slides in the axial direction, to pressurize the upper key toward a synchro ring. A key spring installed between the lower key and the hub to pressurize the lower key and the upper key toward an inner surface of the sleeve.
