Beschreibung
Zusammenfassung:	Disclosed is a caulking method for preventing a piston from being loosened, capable of preventing the piston coupled to a cylinder rod of a hydraulic or pneumatic cylinder from being loosened by the vibration or the like generated during work. Provided is a caulking method for preventing a piston of a hydraulic or pneumatic cylinder from being loosened, the hydraulic or pneumatic cylinder comprising a tube, a cylinder rod reciprocating linearly within the tube, a piston coupled to a screw part of the cylinder rod, and a set screw for preventing the piston from being loosened from the cylinder rod, the caulking method comprising a step of forming screw holes in the screw coupling part of each of the cylinder rod and the piston and coupling the set screw into the screw holes; and a step of compressing the residual space of the screw holes in the direction of coupling the set screw by a compression device after coupling the set screw to the screw holes so as to deform the pitch of the thread in an inlet portion of the screw hole.
