Claims

[Scope of utility model registration request]

Inside the cylinder, there is a first piston, and a multi-stage displaceable second piston that is pushed by the first piston, moves to the first stage integrally with the first piston, and independently moves to the second stage. By fitting the pistons into the respective cylinders and controlling the supply and discharge of the signal working pressure fluid into a predetermined chamber of the cylinder, the second piston is displaced in multiple stages, and as the second piston is displaced in multiple stages, the second piston is displaced in multiple stages. The structure is such that the driven body can be driven in multiple stages using the generated drive output, and a threaded rod that protrudes toward the other piston is attached to one of the first and second pistons inside the cylinder. The first piston of the second piston is screwed together so that the amount of protrusion can be freely adjusted.
A drive device configured to perform stage displacement through contact between the other piston and the threaded rod.
