リンダ。[Scope of Claim for Utility Model Registration] In a hydraulic cylinder with a built-in piston, on the end side of each hydraulic oil port for expansion and compression, which are bored on both ends of the cylinder,
Each orifice port is provided with a poppet-type orifice having an orifice hole in a valve member that is bored and arranged to communicate with an adjacent hydraulic oil flow path, and that is biased by a spring in the outflow direction to close the port portion. A hydraulic cylinder characterized in that the pressure oil in the cylinder after the piston head closes the hydraulic oil port can be discharged only from the orifice hole of the valve member.
