PURPOSE: A synchronizer for manual transmission is provided to prevent the axis direction separation of a key and spring by restricting the movement of the key and spring. CONSTITUTION: A synchronizer for manual transmission comprises a hub(10), a sleeve(20), a key(30), a spring(40) and a stopper plate(50). A gear is formed on the outer circumference of the hub. The sleeve is combined with the outer circumference of hub to move in an axial direction. The key is installed between the sleeve and hub. The spring is installed in the hub so that the key adhere closely to sleeve. The spring offers the elastic force toward the sleeve. The stopper plate is combined in the hub. The stopper plate is formed in order to have two or more other layers on the outer circumference. The stopper plate prevents the axis directional disconnection of the spring and key.
