PROBLEM TO BE SOLVED: To provide a bearing device capable of eliminating presumable adverse effects resulting from variations in dimensions and magnetic property when employing a magnetic bearing as a thrust bearing, and of improving the rotation stability. SOLUTION: In the bearing device A comprising a thrust bearing 30 and a radial bearing 40, the thrust bearing 30 is a magnetic bearing formed by combining a suction provided to the inside and a repulsion part provided to the outside. In this case, the repulsion is preferably set stronger than the suction force. COPYRIGHT: (C)2004,JPO
