PROBLEM TO BE SOLVED: To provide a fluid pressure cylinder with a shock absorbing mechanism having a high absorption effect of collision energy.SOLUTION: A fluid pressure cylinder has an annular outer peripheral side seal portion capable of press-contacting with plates 26 and 27 at diametrical end portions of rubber cushions 22-25; and annular through-hole side seal portions 22b-25b press-contacting with a piston rod 8 on through-holes 22a-25a of the rubber cushions 22-25. Therefore, a fluid collecting part is formed by mutual recessed portions and the piston rod 8. Air in the fluid collecting part is prevented from flowing out to the outside, and the recessed portions are configured so as to stick to the plates 26 and 27, so that the capacity of the fluid collecting part can be brought close to "0" as far as possible, thereby maximizing resistance. |
