Claims

[Scope of utility model registration request]

The power of the input shaft is transmitted to a countershaft, the speed is changed from the countershaft through a plurality of gear trains, and the power is transmitted to the output shaft, and the input shaft and the output shaft are directly connected by a synchronizer to transmit the power. In the gear type transmission, the countershaft includes a friction contact member that comes into frictional contact with the sleeve of the synchronizer and applies a brake to the countershaft when the sleeve of the synchronizer moves in a direction to directly connect the input shaft and the output shaft. A structure for preventing rattling noise of a gear type transmission, characterized by being provided with.
