PROBLEM TO BE SOLVED: To freely control the displacement speed of a piston in a fluid pressure cylinder, and to reduce the manufacturing cost and the size.SOLUTION: A head cover 14 constituting a fluid pressure cylinder 10 includes an adjusting mechanism 22 capable of adjusting the displacement speed of the piston 16 displacing along a cylinder tube 12. The adjusting mechanism 22 is mounted in a first mounting hole 36 of the head cover 14. The adjusting mechanism 22 includes a first needle 82 capable of adjusting the displacement speed when the piston 16 displaces to a proximity of the head cover 14, and a second needle 84 capable of adjusting the displacement speed when the piston 16 displaces along the cylinder tube 12. By rotating the first needle 82, the deceleration degree of the piston 16 near the head cover 14 is adjusted. By rotating the second needle 84, the displacement speed when the piston 16 displaces along the cylinder tube 12 is adjusted. |
