置。[Claims for Utility Model Registration] A steering unit that is operated by a handle, a steering cylinder that steers a steering wheel, a hydraulic line that connects the steering unit and the steering cylinder, and an actuator that is installed in the hydraulic line. A hydraulic oil control means, a detection means for detecting a handle rotation angle and a cylinder stroke amount, and a stroke difference between an actual stroke value obtained from the cylinder stroke amount from the detection means and a target stroke value obtained from the handle rotation angle is set. A fully hydraulic power steering device comprising: a steering wheel position correction control means that outputs a control signal to the actuator to cause hydraulic oil to flow out or be supplied when a value exceeds a value of the vehicle speed; 1. A fully hydraulic power steering system, comprising means for prohibiting steering wheel position correction control by hydraulic oil outflow or hydraulic oil supply when the value is greater than a set value.
