Claims

[Scope of utility model registration request]

A cylinder having a front wall having a sliding opening through which a piston rod can freely slide at one end, and a rear wall having a through hole in the center at the other end,
A long piston rod is provided in the inner diameter part of the cylinder with a part protruding from the sliding opening, and a first piston and a second piston are arranged parallel to each other via a connecting part on the rear wall side, and An O-ring is disposed between the first and second pistons, and the operating speed of the piston due to an external force is controlled by bringing the O-ring into contact with an inner vertical wall between the first and second pistons, thereby reducing air pressure. A shock absorber configured to adjust.
