Zusammenfassung:	PROBLEM TO BE SOLVED: To eliminate the unstable element of the engine torque while efficiently performing the power recovery and the power regeneration by controlling angle of swash plates of a hydraulic pump and a hydraulic motor so that the hydraulic pump and the hydraulic motor perform the pump operation in the case of recovering the hydraulic fluid. SOLUTION: A MT 100 formed of a clutch mechanism and an epicyclic gear mechanism and a HST 200 formed by connecting a hydraulic pump 2 and a hydraulic motor 3 through a closed circuit 4 are arranged in a HMT as a continuously variable transmission for continuously changing the rotation input from an engine 1 and for transmitting it to a right and a left driving wheel 12. A swash plate type piston pump is used for the hydraulic pump 2 and the hydraulic motor 3, and a swash plate 2a of the hydraulic pump 2 and a swash plate 3a of the hydraulic motor 3 are controlled so that the hydraulic pump 2 and the hydraulic motor 3 separately work as a pump in the case of operation for recovering the power of a vehicle.
