Claims

[Claims for Utility Model Registration] 1. A cylindrical cylinder with a bottom, a piston positioned within the cylinder and movable in the axial direction of the cylinder, and one end protruding toward the open end side of the cylinder,
a piston rod that transmits a load to the piston; an incompressible fluid sealed within the cylinder;
an accumulator for absorbing changes in apparent volume of the incompressible fluid caused by movement of the piston rod into and out of the cylinder; and a plug screwed onto the open end of the cylinder to retain the accumulator within the cylinder. and the capacity of the accumulator is greater than or equal to the sum of the volume of the incompressible fluid removed when the piston rod is most deeply inserted into the cylinder and the volume of the plug screwed into the cylinder. A buffer characterized by: 2. The shock absorber according to claim 1, wherein the capacity of the accumulator is four times or more the volume of the incompressible fluid that is removed when the piston rod is most deeply inserted into the cylinder. 3 A uniform male thread is formed on the outer periphery of the cylinder over the entire length, and the closed end surface of the cylinder has a slot, polygon, cross, or non-straight shape that engages with a tool. The shock absorber according to claim 1 or 2, characterized in that a circular hole is carved therein.
