置、 In a vehicle power steering system that uses hydraulic pressure from an oil pump driven by the engine to drive a power cylinder to double the steering force, an electric motor is connected to the hydraulic circuit of the power cylinder in parallel with the engine-driven oil pump. The oil pump is equipped with a means for detecting the vehicle speed, a means for detecting the engine rotation speed, and based on these detection signals, when the engine rotation stops or decreases to a state close to it while the vehicle is running, the electric power is activated. A power steering device for a vehicle, comprising a control means for driving an oil pump;
