PURPOSE: A hydraulic cylinder device with an improved loose-proof structure of a piston nut is provided to prevent a piston nut from being loosened even in high-output by improving durability. CONSTITUTION: A hydraulic cylinder device(10) with an improved loose-proof structure of a piston nut comprises a cylinder(12), a rod(20), a piston(30), and a piston nut(40). The rod is installed inside the cylinder and is reciprocated in a longitudinal direction of the cylinder. The piston is inserted into one end of the rod to be moved with the rod. The piston nut presses the piston and prevents the piston from being separated from the rod. |
