Abstract:
1. A transmission, comprising: an input shaft to receive a rotation of an engine; drive gears respectively attached to the input shaft so as 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 so as to freely rotate individually and 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 a relative rotation; 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 startup clutch interposed between the engine and the input shaft, wherein the input shaft is divided in the axial direction into a first input shaft on a side of the startup clutch and a second input shaft to which the drive gears are attached so as to freely rotate; and a damping mechanism that causes the first input shaft and the second input shaft to rotate integrally when a torque generated in one of the first input shaft and the second input shaft is less than a predetermined torque that is set to more than a maximum torque that is generated in the first input shaft and the second input shaft when the first input shaft is rotated by the engine and is set to less than a spike torque that is generated in the first input shaft and the second input shaft when gears shifts are performed.
