シリンダ装置。 A hollow piston rod is connected to a piston that slides on the inside of a cylinder filled with hydraulic oil so that it can freely slide from the tip of the cylinder, and each oil chamber defined on both sides of the piston of the cylinder is an oil reservoir filled with gas. Each piston is provided with a normally closed valve that is connected to the chamber through a hollow part of the piston rod, and a push rod is provided that penetrates the piston rod to forcibly open these valves in sequence according to the displacement position. In addition to having means for displacing the push rod, an outer tube that is slidably fitted on the outside of the cylinder is supported on the piston rod, and a compressed gas sealed in the cylinder is provided between the outer tube and the piston rod and faces the tip of the cylinder. A cylinder device characterized by forming a pressure chamber.
