ング。 A hydraulic cylinder device for driving a steering mechanism includes a throttle arranged in each oil passage for supplying and discharging hydraulic oil to an oil chamber on both sides of a piston, and a flow passage with a large oil flow area arranged in parallel with the throttle, A valve device is provided between the increasing flow path and the throttle, and is arranged between the valve device and the steering mechanism, the valve device being able to select at least a mode in which the flow path becomes the increasing flow path or a mode in which the mode becomes the throttle, and the steering angle is set at a neutral position. A power steering system comprising: an interlocking mechanism that drives the valve device in a mode in which the valve device operates in a mode in which the valve device becomes the throttle when it is within a certain range around the center, and in a mode in which it becomes the increasing flow path when it exceeds the certain range. .
