BEARING DEVICE, METHOD OF MANUFACTURING BEARING DEVICE AND INFORMATION RECORDING AND REPRODUCING DEVICE

PROBLEM TO BE SOLVED: To provide a bearing device capable of suppressing deviation of an axial center of each component and a method of manufacturing the bearing device. SOLUTION: The bearing device 10 is provided with a shaft 41 having a flange 44 formed thereon, a sleeve 43, a first rolling bearing 51 and a second rolling bearing 52. A first tapered portion 61 is formed on the boundary between the shaft 41 and the flange 44, and a second tapered portion 62 capable of abutting on the first tapered portion 61 is formed on an inner ring 51a of the first rolling bearing 51. A third tapered portion 63 and a fourth tapered portion 64 are formed between an inner peripheral face 45a of a spacer 45 arranged within the sleeve 43 and an inner peripheral face 43a of the sleeve 43. A fifth tapered portion 65 capable of abutting on the third tapered portion 63 is formed on an outer ring 51b of the first rolling bearing 51, and a sixth tapered portion 66 capable of abutting on the fourth tapered portion 64 is formed on an outer ring 52b of the second rolling bearing 52. With each tapered portion abutting on each other, the first and second rolling bearings 51, 52 are fixed between the shaft 41 and the sleeve 43. COPYRIGHT: (C)2010,JPO&INPIT
