FLUID PRESSURE CYLINDER

PROBLEM TO BE SOLVED: To provide a fluid pressure cylinder capable of reducing the number of article numbers of a piston rod.SOLUTION: A single-acting type fluid pressure cylinder 100 extends upward according to a supply of a working fluid into a drive chamber 1 under a piston 20 sliding in a cylinder tube 10, and has a cushion function for suppressing an extension operation before the piston 20 reaches a stroke end of the extension side. The fluid pressure cylinder 100 includes: a piston rod 30 which is fitted in an upper part of the piston 20 and which defines a rod inner chamber 3 between itself and the piston 20; a cushion chamber 2 which is defined between the piston rod 30 and the cylinder tube 10; a communication hole 32 which is provided at the piston rod 30 and which communicates the cushion chamber 2 and the rod inner chamber 3; and an annular spacer 50 which is arranged at a lower end of the piston rod 30, which is pinched between the piston rod 30 and the piston 20 and which has an orifice 51 exhibiting a cushion function by applying resistance to the flow of the work fluid from the cushion chamber 2 to the rod inner chamber 3.
