Abstract

A transmission for a vehicle for performing a shift manipulation at a desired time while ensuring a favorable operation feeling. A lost motion member is arranged in a shift drive force transmitting mechanism arranged between a shift spindle and a shift drum, and a rotary position of the shift drum is resiliently held by a shift stopper mechanism in a state where one of a plurality of gear trains is established or in a neutral state. A state which allows a changeover operation of an established state of a plurality of gear trains due to an action of a shift drive force which is temporarily accumulated by a lost motion means and a state which interrupts the changeover operation can be changed over by a shift restricting mechanism which is provided as a part separate from a shift stopper mechanism.
