Abstract
A vehicular transmission has a structure which enables a reverse idle gear to absorb and reduce excessive back torque inputted from drive wheels. At the time of reverse traveling motion, a counter shaft and a reverse gear are connected to each other through the intermediation of a clutch mechanism, whereby the power of the counter shaft is transmitted from the reverse gear, a driven gear, a hollow shaft, and a drive gear to the drive shaft by way of a final gear. When a large back torque is inputted to the final gear from the drive shaft, the inputted back torque is transmitted to the drive gear, and is then further transmitted to the driven gear by way of the hollow shaft. Since the hollow shaft is thin-walled and has reduced rigidity, it undergoes circumferential twisting due to the back torque inputted, whereby the back torque is reduced.
