A support structure for a blanket cylinder of an offset printing press includes: a first eccentric bearing that is rotatably supported by frames of the offset printing press; a second eccentric bearing that is rotatably supported by the first eccentric bearing so as to rotatably support an shaft of a blanket cylinder; a printing pressure adjustment device that rotates the first eccentric bearing relative to the frames, thereby adjusting a clearance between an impression cylinder and a blanket cylinder; and a throw-on device that rotates the second eccentric bearing relative to the first eccentric bearing, thereby performing throw-on and throw-out operations. In the thus arranged support structure, a throw-on distance of the throw-on device is variable.
