Abstract:
1. A transmission comprising: multiple stage shift gears fixed to or relatively rotatably supported with driving force transmission shafts; a plurality of clutch rings each having meshing parts on both sides for meshing with the respective shift gears that take two speeds or more away from each other, so as to connect the respective shift gears to the driving force transmission shafts and perform a shifted output; a shift operation part that selectively operates the clutch rings; guide parts that are provided for respective stages of the shift gears between the clutch rings and the driving force transmission shafts so that, when meshing engagements of the clutch rings of an upper stage and a lower stage are simultaneously performed through the operation of the shift operation part in which the operation of the shift operation part is selected from the group consisting of a shift-up operation of the operation part and a shift-down operation of the operation part, axial forces oriented in opposite directions that are a meshing-engagement direction and a meshing-release direction are generated on the clutch rings of the upper stage and the lower stage.
