Claims

[Scope of utility model registration request]

A power steering system is equipped with a control valve that switches depending on input rotation from a steering wheel, and selectively supplies pressure oil to hydraulic actuators linked to wheel linkages through this control valve. a means for detecting the vehicle speed; a reaction force chamber that expands and contracts in accordance with switching of the control valve; and a reaction force chamber that operates to counteract the switching of the control valve in accordance with the loaded load and vehicle speed. A power steering device that conducts high pressure from the boat and is equipped with a hydraulic switching valve.
