Claims

[Scope of utility model registration request]

In a pneumatic shock absorber installed between a base and a self-closing lid plate that is self-closingly attached to the base, its volume is reduced as the lid plate moves in the closing direction. Atmosphere communication, which includes an air chamber and a buffer orifice that allows the air chamber to communicate with the atmosphere, and has a passage cross-sectional area larger than the passage cross-sectional area of the orifice, and that allows the air chamber to communicate with the atmosphere. and an on-off valve that can open and close the air communication port, and a valve opening that can open the on-off valve at the predetermined opening of the cover plate in order to rapidly close the cover plate from a predetermined opening. A pneumatic shock absorber with a self-closing lid plate, characterized by being provided with a mechanism.
