To perform high precise printing by smoothly rotating a cooling roller, a guide roller or the like of a gravure printing machine or the like and by smoothly moving a printing film without loosing the film or applying impossible tension thereto.

This printing machine has a motor 71 for rotating the cooling roller 52, and a rotation force of the motor 71 is transmitted to the cooling roller 52 through a speed reducer 73, a shaft 44, a pulley 612, a belt 62, a pulley 611, a shaft 43, a contact seal type bearing 33, and a roller shaft 422. A rotation force of the shaft 43 is indirectly transmitted from the shaft 43 and the outer ring of the bearing 33 to the inner ring of the bearing 33 and the roller shaft 422 via a contact seal disposed between the outer ring and the inner ring of the bearing 33. The outer ring and the inner ring of the bearing 33 are frictionally bonded by the contact seal.
