Abstract
A transmission includes an input shaft to receive the rotation of an engine, drive gears attached to the input shaft so as to freely rotate, an output shaft to output rotation following a gear shift, driven gears that are attached to the output shaft so as to freely rotate and mesh with the drive gears, an engagement mechanism to fix a gear to be used in a gear shift, from among the drive gears, to the input shaft to be incapable of relative rotation prior to a gear shift, and a selector mechanism to fix, during the gear shift, the driven gear of a corresponding gear position, which meshes with the drive gear fixed to the input shaft by the engagement mechanism, to the output shaft to be incapable of relative rotation.
