It is formed so that it becomes lower continuously or stepwise from the position toward the load end side, and the load borne by each thread part of the female thread of the cylinder is equalized to bring the stress distribution state as close as possible to a uniform stress distribution state. A cylinder breakage prevention device for a hydraulic cylinder, characterized in that the cylinder is configured to prevent breakage of the cylinder.
