<p>PROBLEM TO BE SOLVED: To provide a cylinder device capable of inhibiting or preventing a rod integrally moving with a piston from rotating.SOLUTION: A cylinder device 1 includes: a cylinder 2 including a trunk part 3 formed into a hollow shape and a bottom part 4 closing an end part of the trunk part 3; and a piston 5 which is disposed in the cylinder 2 so as to move in an axial direction of the cylinder 2 and has a cross section shape formed into a circle. The cylinder device 1 includes: multiple rods 12, 12 which extend in the axial direction of the cylinder 2, integrated with the piston 5, and has cross sectional shapes formed into circles; and a lid part 10 where multiple through holes 10a, 10a (10d, 10d), through which the multiple rods 12, 12 respectively penetrate, are formed, the lid part 10 which seals an opening end of the cylinder 2 in an air-tight manner.</p> |
