<p>A cylinder apparatus for a rotary printing press includes a pair of inner bearings (4;6), an outer bearing (3), a pair of frames (1A;1B), a pair of cylinders (7,8), a motor (15), and a pair of abutting members (30a). The pair of inner bearings rotatatively support two end shafts of at least one plate cylinder. The inner bearings have engaging projections. The outer bearing pivotally supports one of the inner bearings. The pair of frames are arranged to oppose each other through a predetermined distance, and pivotally support the outer bearing and the other one of the inner bearings. The pair of cylinders pivot the inner bearings supported by one of the frames and the outer bearing. The motor pivots the outer bearing supported by the other one of the frames. The pair of abutting members are supported by the frames. The engaging projections of the inner bearings abut against the pair of abutting members when the plate cylinder (7) abuts against a blanket cylinder (8) upon driving operation of the cylinders. <IMAGE></p> |
