Abstract
In a fluid pressure cylinder, a piston unit, which is displaced along an axial direction under the supply of a pressure fluid, is disposed in the interior of a cylinder tube of the fluid pressure cylinder. The piston unit includes a disk shaped plate body connected to one end of a piston rod, and a ring body connected to an outer edge portion of the plate body. The plate body is formed from an elastically deformable metal material, and by the plate body becoming elastically deformed and flexing when the ring body of the piston unit abuts against the head cover or the rod cover, shocks applied with respect to the piston unit are buffered.
