Claim:
1. A transmission, comprising: an input shaft to receive a rotation of an engine; drive gears respectively attached to the input shaft to freely rotate individually; an output shaft disposed parallel to the input shaft in order to output rotation following a gear shift; driven gears respectively attached to the output shaft to freely rotate individually and to mesh with the drive gears; an engagement mechanism to fix a drive gear to be used in a gear shift individually, from among the drive gears, to the input shaft to be incapable of relative rotation; and a selector mechanism to fix, during the gear shift, a driven gear of a corresponding gear position individually, which meshes with the drive gear fixed to the input shaft by the engagement mechanism, to the output shaft to be incapable of the relative rotation; a hub that is fixed to the input shaft between adjacent gears from among the drive gears attached to the input shaft to freely rotate; and a sleeve that is held by the hub to freely move in an axial direction of the input shaft, whereby the sleeve engages with one of the adjacent gears when moved to one side in the axial direction and engages with an other adjacent gear when moved to another side in the axial direction, wherein the drive gears are arranged on the input shaft such that adjacent gears are separated by at least two gear positions.
