ンパ機構の真空部補正機構。[Claims for Utility Model Registration] A cylinder having an oil chamber filled with damper oil, a piston that moves within the oil chamber of the cylinder in conjunction with the opening/closing operation of a door, and a cylinder provided on the piston and divided by the piston. a check valve that only allows damper oil to flow into one side of the oil chamber; a communication passage that is divided and communicates between the oil chambers; and a communication passage that is provided in a part of the communication passage and that allows damper oil to pass through. A damper mechanism comprising a regulating means for regulating the flow rate and regulating the door closing speed by hydraulic pressure acting on the piston, wherein the damper mechanism is slidably provided in the oil chamber of the cylinder and divides the oil chamber, and has a piston. A vacuum section is generated in the cylinder chamber by the movement of the piston that moves when the door is closed. A vacuum section correction mechanism of a damper mechanism, characterized in that it is configured to prevent the above.
