ABSTRACT:
A synchro-mesh type gear transmission includes a clutch hub rigidly mounted on an output power shaft. The clutch hub is provided with axial slots in which springs are axially inserted. The springs urge a synchronizer ring against a conically tapered surface of a driven shift gear which is mounted on the output power shaft so as to be rotatable. Thus, the synchronizer ring exerts a frictional resistance against rotation of the driven shift gear. A cylindrical sleeve is rigidly inserted in each of the guide slots. Each spring is inserted in a respective cylindrical sleeve so as to be prevented from being deformed in the direction in which the synchronizer ring rotates. A guide rod may be inserted in the cylindrical coil spring disposed in the cylindrical sleeve as a further support against deformation.
