PURPOSE:To make a helical gear provided at the shaft of a printing cylinder shiftable without using any tool. CONSTITUTION:An actuator 30 for immovably setting a rod 27 in the axial direction is rotatably provided in the shaft 2 of a printing cylinder, the actuator 30 and helical gear 15 are mounted to a case 32 having a ring groove 32a into which a cam follower 12 is inserted, and the case 32 is fitted into a sleeve 22 for immovably setting the shaft 2 of the printing cylinder via screw spline 34. |
