プ。 A rotor connected to a driving side rotating shaft and having a plurality of vanes arranged radially on its circumferential surface and capable of protruding and retracting; a rotor connected to a driven side rotating shaft and rotatably fitted to the rotor; A cam ring equipped with a pump chamber that supplies and discharges hydraulic oil as the vane slides, and automatically generates drive torque from the drive side to the driven side according to the rotation difference between the front and rear wheels. 4. An orifice is provided at a position of the vane facing the pump chamber so as to pass through the vane with different opening areas on both sides and to vary the flow resistance of hydraulic oil depending on the direction of relative rotation between the rotor and the cam ring. Differential pump for wheel drive vehicles.
