PROBLEM TO BE SOLVED: To materialize high rotation accuracy without variation of rotary axis center of a coating roll even if the coating roll bends or external force in a direction other than gravity direction acts on the coating roll. SOLUTION: This bearing structure is provided with a hydraulic static pressure bearing 26 rotatably supporting a rotary shaft 22 of a roll 14 and a plain bearing 27 supporting the hydraulic static pressure bearing 26 and allowing inclination of the hydraulic static pressure bearing 26 as to follow only deflection in the gravity direction of the roll 14.
