PURPOSE: To promote normal rotation of an input shaft on the driving source side by regulating the reverse rotation of the input shaft in a variable displace ment pump and motor source to which a working fluid is supplied in the case where the pressure of the working fluid stored in an accumulator is lowered. CONSTITUTION: In the case of starting or traveling a vehicle with operating oil stored in an accumulator 14, a swash plate 11a is operated to operate a variable displacement pump and motor 11 as a variable displacement motor. One input shaft 4a in a differential gear mechanism 3 is rotated through a transmission 2 by an engine 1, and the other input shaft 4b is rotated by the variable displacement pump motor 11. When the operating oil in the accumulator 14 runs out, the other input shaft 4b is kept from being rotated in the reverse direction by a one-way clutch 15. Accordingly, the engine 1 can rotate only an axle 10 efficiently without operating the variable displacement pump and motor 11.
