Zusammenfassung:	PURPOSE:To stabilize rotational movement in a bearing system of a spidle motor adopted for a disc device or the like by providing a magnet which generate magnetic force on a part of a bearing surface of bearing members for journalling a magnetic shaft member. CONSTITUTION:A magnetic circuit C is formed by providing a magnet 3 between sintered alloy bearing members 2a and 2b which support a shaft member 1 made of magnetic material. Attraction force is generated on the shaft member 1 in a G direction to always cause linear contact. Mechanical oscillations and unbalanceness are eliminated, so that inexpensive and stable rotation is obtained.
