PROBLEM TO BE SOLVED: To provide a dynamic pressure bearing device at low cost having high shaft strength and capable of maintaining desired rotation precision. SOLUTION: A first flange part 9 and a second flange part 10 are bonded and fixed at a predetermined position on an outer peripheral face 2a1 of a shaft part 2a. An adhesive clearance is provided among an inner peripheral face 9d of the first flange part 9, an inner peripheral face 10d of the second flange part 10, and the outer peripheral face 2a1 of the shaft part 2a in a bonding and fixing part 14 of the first flange part 9, the second flange part 10, and the shaft part 2a. Adhesive 13 is filled into the adhesive clearance and a spiral channel 12 and is solidified. COPYRIGHT: (C)2007,JPO&INPIT
