A rotating-shaft seal section protective plate including a cylindrical section that covers the periphery of part of a rotating shaft, a small-diameter flange-shaped section formed at an end on the rotor side, of the cylindrical section, and a large-diameter flange-shaped section formed at an end on the rotating-shaft seal section side, of the cylindrical section, is disposed between the rotor and the rotating-shaft seal section. The rotating-shaft seal section protective plate divides the interior of a chamber into a portion on the rotor side and a portion on the rotating-shaft seal section side by means of the large-diameter flange-shaped section and leads a liquid injection medium (corresponding to each of a peeling liquid and a cleaning liquid) to the discharge port by means of the small-diameter flange-shaped portion.
