。[Claims for Utility Model Registration] (1) A piston rod is movably inserted into the cylinder via a piston, and a cushion bearing provided at the end of the piston rod fits into a cushion hole provided in the bottom of the cylinder, causing an impact. In a hydraulic cylinder for relaxation, a guide integrally provided with a stopper is fitted to the end of the piston rod, a cushion bearing is inserted into the outer periphery of the guide, and the guide is fixed with a pin inserted into the piston rod.
The pin is a hydraulic cylinder held by a nut screwed onto the outer periphery of the end of the piston rod. (2) The hydraulic cylinder according to claim 1 of the utility model registration claim, in which radial holes are formed in the ends of the guide and the piston rod, and pins are inserted into the holes from the lateral direction to connect the guide to the piston rod. . (3) The hydraulic cylinder according to claim 1, wherein a nut is screwed into the piston rod at a position that seals the hole. (4) The hydraulic cylinder according to claim 1, wherein the stopper is a flange provided at the end of the guide. The brief description of the drawing has been amended as follows. On page 9, line 7 of the specification, the phrase "12...cushion chamber" is corrected to "12...cushion hole."

Claims

[Scope of Claim for Utility Model Registration] (1) A piston rod is movably inserted into the cylinder via a piston, and the cushion bearing provided at the end of the piston rod fits into the cushion chamber provided at the bottom of the cylinder, causing an impact. In a hydraulic cylinder for relaxation, a guide integrally provided with a stopper is fitted to the end of the piston rod, a cushion bearing is inserted into the outer periphery of the guide, and the guide is fixed with a pin inserted into the piston rod.
The pin is a hydraulic cylinder held by a nut screwed onto the outer periphery of the end of the piston rod. (2) The hydraulic cylinder according to claim 1 of the utility model registration claim, in which radial holes are formed in the ends of the guide and the piston rod, and pins are inserted into the holes from the lateral direction to connect the guide to the piston rod. . (3) The hydraulic cylinder according to claim 1, wherein a nut is screwed into the piston rod at a position that seals the hole. (4) The hydraulic cylinder according to claim 1, wherein the stopper is a flange provided at the end of the guide.
