When it flows into one pressure chamber, it flows out via the other pressure chamber, and a control orifice is provided in the flow path between both pressure chambers. A steering control device in which a pressure chamber is connected to one pilot chamber of a steering valve, and the other pressure chamber is also connected to the other pilot chamber of the steering valve.
