Claims

[Claims for Utility Model Registration] (1) A cylinder, a first pressure chamber and a second pressure chamber spaced apart in the axial direction inside the cylinder and each filled with a pressure fluid, and a first pressure chamber. A first piston is fitted in a chamber so as to be slidable in the cylinder axis direction and has an orifice extending through the cylinder axis; a first piston rod that is pulled out of the chamber and protruded to the outside of the cylinder;
a second piston fitted in the pressure chamber so as to be slidable in the cylinder axial direction; and a third piston fitted in the second pressure chamber so as to be slidable in the cylinder axial direction and having an orifice extending therethrough in the axial direction. a second piston, one end of which is connected to the third piston, the other end of which extends along the cylinder axis direction and is connected to the second piston.
a piston rod, a stopper means capable of preventing sliding of the third piston, and a stopper release means that is engaged with the stopper means and changes shape at low temperatures to displace the stopper means so as to permit sliding of the third piston. A damper stay characterized by the following. (2) The damper stay according to claim (1), wherein the pressure fluid sealed in the first pressure chamber and the second pressure chamber is a high-pressure gas. (3) The damper stay according to claim (1) or (2), in which the stopper means is disposed on the third piston so as to be movable in the diametrical direction, and is advanced and locked in contact with the cylinder. (4) The damper stay according to any one of claims (1) to (3), in which the stopper release means is made of a shape memory alloy. (5) The damper stay according to claim (4), in which the shape memory alloy is formed into a compression coil spring and changes its shape at low temperatures to change the set load.
