第１項記載のダンパ。[Claims for Utility Model Registration] (1) A piston rod is movably inserted into the cylinder via a piston, and the piston has a first oil chamber on the piston rod side and a second oil chamber on the opposite side from the piston rod. A pressurized gas chamber is provided in the upper part of the second oil chamber, a passage is provided in the piston to allow the first and second oil chambers to communicate, and a relief valve is provided in this passage so as to be able to open and close freely. A damper in which the first and second oil chambers are communicated through a bypass, and a pair of check valves that act in opposite directions are provided in the bypass so as to be openable and closable. (2) The damper according to claim 1, wherein the relief valve opens when the pressure in the first oil chamber exceeds a predetermined pressure. (3) The damper according to claim 1, in which a pair of check valves are opened and closed simultaneously or selectively by external operation.
