PURPOSE: A speed-sensitive power steering system for a vehicle is provided to control a flow flowing into a gearbox through an oil pump by various modes according to the traveling speed, to improve the operating force or performance of a steering wheel. CONSTITUTION: In a speed-sensitive power steering system for a vehicle, oil in an oil reservoir(10) is compressed through an oil pump(20) and the compressed oil flows into a gearbox(40) of a steering gear through an actuator(30) connected to a control part(100). The oil flowed into the gearbox is circulated to the oil reservoir through the actuator. An operating part(200) having plural connection parts(210,220,230) is connected to the input side of the control part.
