摘要： PROBLEM TO BE SOLVED: To provide a hydraulic cylinder capable of generating sufficient impact force at a stroke end of a piston without increasing a cylinder length of the hydraulic cylinder, and reducing noise caused by impact force.
SOLUTION: A pressure receiving face plate 29 is mounted on an end face of the piston 12 and a supporting member 26 is erected there. A disc spring 27, a plate 25 and a plunger 28 are loosely fitted to the supporting member 26 successively from a pressure receiving face plate 29 side, and these members are locked by a flange portion 26a. When the piston 12 approaches the stoke end, a plunger 28 is inserted into an oil passage 20b to apply cushioning action to the piston 12. Further as a clearance between the plate 25 kept into contact with a cylinder bottom 17 and the pressure receiving face plate 29 is reduced, squeezing effect caused by escaping of oil from the fine clearance can be generated.
