Abstract

A transmission apparatus for a vehicle comprising a casing, an input shaft, an output shaft parallel to the input shaft having at least four gear trains interposed between the two shafts through respective clutches, at least one of the respective clutches being an in-common clutch used in common to two of the at least four gear trains, and at least one selection mechanism provided separately from the common clutch. The two gear trains are those differentiated in change speed stage one from another by three stages. The two gear trains are arranged so that in the case of power transmission through any selected gear train other than the two gear trains, such one of the two gear trains that has a change speed stage nearer the change speed stage of the selected gear train has been selected by the selection mechanism.
