Abstract
A transmission for a vehicle has a main shaft and a counter shaft, which are supported in a transmission case by bearings. Gears on the main shaft and gears on the counter shaft include: shifter gears which are not rotatable but axially movable relative to the shaft, and fixed gears which are rotatable but not axially movable relative to the shaft. Dog clutches are provided between the shifter gears and the fixed gears, and outer races of the bearings supporting the main and counter shafts are affixed to the transmission case. Vibration-absorbing elastic members are pressed against the outer races from axially outside and are set to have a volume of 50% or more of the volume of the outer races. With such configuration, the vibration of the bearings supporting both the main and counter shafts of the transmission is attenuated, and striking noise caused by shifting is reduced.
