Claims

[Scope of utility model registration request]

An annular piston is fitted into a cylinder that has a check valve on the outside of the rear end that allows a small amount of air to flow through it at all times, and a cylindrical body that is integrated with the annular piston protrudes from the tip of the cylinder so that the annular piston is inserted into the tip of the cylinder. Furthermore, a disk-shaped piston is fitted into the cylinder, and a spring is arranged between the inner surface of the rear end of the cylinder to constantly urge the disk-shaped piston forward. A two-stage sliding air damper in which a piston rod protrudes from the tip of a cylinder so that a disc-shaped piston can be locked to the tip of the cylinder.
