Abstract

A transmission for vehicles including a plurality of alternative gear trains. It comprises a mechanism for bringing an end face of a boss of at least one gear, not concerning the power transmission, on a shaft and a surface of another member, relatively rotating with respect to the gear, on the shaft into slideable contact with each other under force of a spring. Vibration and noise due to those gear trains not contributing to the power transmission are effectively prevented.
