To dispose a hydraulic continuously variable transmission used for a FR drive type vehicle, compactly in a floor tunnel.
A continuously variable transmission disposed in an FR drive type power transmission path so as to shift rotatory-driving force of an engine in a continuously variable state is constituted having a cam plate type hydraulic pump P and a cam prate type hydraulic motor M of variable displacement type connected through a hydraulic closed circuit 51. When the hydraulic pump P is rotatory-driven by an engine, the hydraulic motor M is rotatory-driven receiving the supply of discharge oil from the hydraulic pump P, and the rotatory-driving force of the hydraulic motor M is transmitted to rear wheels. The hydraulic pump P, the hydraulic closed circuit 51 and the hydraulic motor M are arranged in series in this order from the engine output shaft side toward the rear of a vehicle, and hydraulic servo mechanism 45, 65 for operating to rotate the cam plates of the hydraulic pump P and hydraulic motor M in the inclined state, and a hydraulic control valve V for performing various hydraulic control, are arranged below hydraulic continuously variable transmission mechanism.
