Claims

[Claims for Utility Model Registration] 1. A plurality of first cylinder chambers arranged coaxially with each other, a plurality of second cylinder chambers arranged in parallel to the first cylinder chambers, and a plurality of second cylinder chambers arranged in parallel with the first cylinder chambers; a plurality of first pistons respectively housed in one cylinder chamber, second pistons respectively housed in the second cylinder chamber, a first piston rod linking the first pistons with each other; a second piston rod that connects the two pistons with each other; a connecting member that connects the first piston rod and the second piston rod that are parallel to each other; and all of the first piston and the second piston. a first supply port that supplies actuation fluid pressure to the piston so that the cylinder output is the sum of all its piston forces;
The first piston and the first piston are actuated by the working fluid pressure from the first supply port by supplying working fluid pressure only to some pistons of the first piston and the second piston. A cylinder device comprising: a second supply port for returning two pistons. 2. The first piston rod and the second piston rod are each formed by a plurality of rods disposed coaxially with each other in an uncoupled state, and the first piston rods and the second piston rods are respectively formed of a plurality of rods in an uncoupled state. The cylinder device according to claim 1, characterized in that the cylinder devices are linked. 3. The first pistons and the second pistons are connected to the first piston rod and the second piston rod.
2. The cylinder device according to claim 1, wherein the cylinders are connected to each other by a piston rod.
