Problems to be Solved by the Invention A carrier is provided which has an input gear on an input shaft and an output gear on an output shaft coaxially adjacent to each other, and meshes with each of these gears separately to pivotally support a revolving double gear. At the same time, a friction clutch section for connecting and disconnecting the output shaft to the carrier and a hydraulic piston operating to the friction clutch are connected to one side of the carrier, and a coupling member is connected to the outside of the piston in the axial direction. In a transmission device that is equipped with a friction clutch that connects and disconnects the transmission case and carrier, the axial dimension of the transmission case becomes long, and separate coupling members are required for each, making it more compact.
This tends to be disadvantageous in terms of cost reduction.
