When 1 is loosened and the fixing force of the plate cylinder 101 by the tapered sleeve 129 is reduced, a predetermined fixing force is to be obtained by retightening the loosened nut 131 with a special tool. However, when this operation is performed in a state where the plate cylinder shaft 102 is attached to the frames 115 and 116, the operation is performed by inserting a tool into the frame 115, and a sufficient working space cannot be obtained. It is difficult for the operator to check the nut 131 and the work becomes difficult, which places a burden on the operator. In addition, the nut 131 (taper sleeve 12
There was a major problem in terms of workability, such as the possibility that a predetermined fixing force could not be applied to 9).
