Claims

[Scope of utility model registration request]

In a fluid pressure cylinder in which a cover with cylinder ports is attached to both ends of the cylinder tube, and a piston mounted on a piston rod is slidably inserted into the cylinder tube, the cover is attached to one or both ends of the cylinder tube. A flow path is provided between the cylinder port and a chamber defined by a piston in the cylinder tube, and a cylindrical cushion spacer is provided with a gap between the cover and the cylinder tube to form an air flow path. Provided integrally or separately, the gap is communicated with the cylinder port via the throttle valve inside the cover, and on the piston rond,
A fluid pressure cylinder with a buffer mechanism, characterized in that a cushion gasket is provided in contact with the inner surface of the cushion spacer to seal therebetween, and a groove is provided in the inner surface of the cushion spacer on the side closer to the cover.
