In the hydraulic cylinder in which the cylinder tube and both the head side and bottom side bearing members are integrated by caulking and deforming the caulking part of the cylinder tube located on the outer periphery into both the annular grooves with the same forming roll, the above-mentioned A hydraulic cylinder characterized in that a caulking recess for preventing rotation is formed in at least one corner formed by the outer periphery of the head side and bottom side bearing members and both sides of the annular groove. (2) Annular grooves are formed on the outer peripheries of the head-side bearing member that closes one end of the cylinder tube and the bottom-side bearing member provided at the other end, and the cylinder tube is caulked on the outer periphery of both annular grooves. In a hydraulic cylinder in which the cylinder tube and both the head side and bottom side bearing members are integrated, the axis of the annular groove is aligned with the cylinder by caulking and deforming the cylinder tube into both the annular grooves using the same forming roll. A hydraulic cylinder that is eccentric by a predetermined amount with respect to the axis of the tube.
