徴とする油圧式動力舵取装置。[Claim for Utility Model Registration] In a hydraulic power steering device in which a piston is slidably fitted inside a cylinder, a metal piston ring is attached to the outer peripheral surface of the piston, and the piston is located near the stroke ends on both sides. When the inner peripheral surface of the cylinder corresponding to the piston ring is divided into multiple places in the circumferential direction, recesses smaller in width than the fitting width of the piston to the cylinder are formed, and the outer circumference of the piston near the piston ring is Recesses corresponding to the recesses on the cylinder inner circumferential surface are formed at multiple locations dividing the surface in the circumferential direction, and when the piston reaches the vicinity of the stroke end, the recesses on the cylinder inner circumferential surface and the piston outer circumferential surface are formed. A hydraulic power steering device characterized in that oil chambers on both sides of a piston of a cylinder communicate with each other via a recess.
