PROBLEM TO BE SOLVED: To provide a print cylinder in which a sleeve cylinder is fitted to a rotary shaft so as to be inserted into and detached from, freely, capable of surely coupling the sleeve cylinder and the rotary shaft without wobble and vibration, and capable of surely separating them.SOLUTION: A sleeve cylinder support taper surface 25 is formed on a depth side of a rotary shaft 20, and a taper surface 38 is formed on a depth side of an inner diameter part of a sleeve cylinder 30. The sleeve cylinder 30 is inserted along the rotary shaft 20, and the taper surface 38 is brought into contact with the sleeve cylinder support taper surface 25 tightly, for fitting, and coupling the rotary shaft 20 and the sleeve cylinder 30. Therefore, the sleeve cylinder 30 can be surely coupled with the rotary shaft 20 without wobble and vibration, and the sleeve cylinder 30 can be drawn therefrom for separating them. |
