ロールバルブ。[Scope of Utility Model Registration Claim] A power cylinder that has a spool inside that slides according to the amount of steering of the steering wheel, and that displaces a part of the steering mechanism by forming an oil path according to the movement of the spool. In a power steering device equipped with a control valve that sets a pressure supply path, the diameter of the oil path is varied according to the length of the oil path that branches to positions in both directions across the neutral position of the spool in the control valve. A control valve for a power steering device that is characterized by a
