摘要：
A first hydraulic pump and a second hydraulic pump are respectively mounted to both ends of a rotary shaft in an electric motor, whereby it is possible to drive both of the first hydraulic pump and the second hydraulic pump by one electric motor. Since the electric motor is driven and controlled so as to have any higher rotational speed among a rotational speed of the first hydraulic pump for obtaining an amount of working fluid required in a hydraulic control circuit for a power steering apparatus and a rotational speed of the second hydraulic pump for obtaining an amount of working fluid required in a hydraulic control circuit for a power train by a hydraulic pump drive controlling portion, it is possible to necessarily and sufficiently secure the working fluids respectively required in the power steering hydraulic control circuit and the power train hydraulic control circuit which are independent from each other, by a little electric power consumption.
