とするシヨツクアブソーバ。 In a shock absorber in which a piston having a throttle hole is provided in a cylinder filled with liquid, the piston is formed into a cylindrical case body, and both end walls of the piston are connected to both liquid chambers of the cylinder partitioned by the piston. A liquid circulation hole is provided to allow the sealing liquid to flow through without resistance, and a movable wall is provided in the piston that moves within the piston with its outer periphery facing the inner wall of the case with a small gap, while the liquid circulation hole is provided in the peripheral wall of the piston. and a gap between the piston and the cylinder to provide communication between the two liquid chambers. When moving, it receives the dynamic pressure of the sealing liquid flowing in from the liquid flow hole and moves to the throttle hole forming position to reduce its opening area, and moves to the throttle hole forming position in the other of the liquid flow holes. A shock absorber characterized in that it is provided with a check valve that prevents flow of sealing liquid when the movable wall moves back.
