FLUID BEARING DEVICE AND ITS MANUFACTURING METHOD

PROBLEM TO BE SOLVED: To provide a fluid bearing device in which a bearing span of a radial bearing section can be extended, and a bearing sleeve is installed into a housing easily and highly accurately. SOLUTION: A fluid bearing device 1 comprises multiple, here, two bearing sleeves 81, 82 arranged in the axial direction, a shaft member 2 inserted in an inner periphery of the bearing sleeve, and a housing 7 housing the respective bearing sleeves 81, 82. On the inner peripheral surfaces of the bearing sleeves 81, 82, radial bearing surfaces A1, A2 are formed, respectively which form bearing clearances with a peripheral surface 2a1 of the shaft member 2. An adjacent first bearing sleeve 81 and a second bearing sleeve 82 are fixed in an engaging member 83 engaged in an approaching direction for the both, and the radial bearing surfaces A1, A2 of the both bearing sleeves 81, 82 are formed by moulding.
