Claims

[Claims for Utility Model Registration] 1. A compressed air cylinder in which compressed air is applied to one side of the piston within the cylinder body, and incompressible fluid is applied to the other side of the piston to cause the piston to slide into the cylinder body. In the apparatus, a buffer member is provided on the other side of the piston on which the incompressible fluid acts, and when the buffer member moves to a side surface of the cylinder body due to sliding of the piston,
A hole into which the buffer member is loosely fitted is provided on the side surface of the cylinder body, and the cross-sectional area of at least one of the buffer member and the hole is gradually changed, so that the buffer member is loosely fit deeper into the hole. A compressed air cylinder device characterized in that the gap between the buffer member and the hole is gradually reduced. 2. The compressed air cylinder device according to claim 1, wherein the buffer member has a cross-sectional area that gradually changes and becomes tapered as it moves away from the piston.
