PROBLEM TO BE SOLVED: To provide a dual synchronizer of a manual transmission for improving shifting feeling and an operation feeling by preventing a synchronous collapse phenomenon of the manual transmission for an automobile. SOLUTION: This dual synchronizer has a first key set and a second key set, composed of a plurality of keys separated by a prescribed angle in the circumferential direction of a synchronizer ring. The first key set brings the synchronizer ring into close contact with a clutch gear at synchronism start time. The second key set presses the synchronizer ring to the clutch gear, after finishing synchronism, so as to continuously keep the frictional force between the synchronizer ring and the clutch gear. |
