PROBLEM TO BE SOLVED: To prevent a fluid bearing device from being contaminated with oil when oiling. SOLUTION: The fluid bearing device is provided with an oil repellent part P1 by applying an oil repellent agent to an upper end face 7a3 of a holding member 7. Consequently, even if oil overflows until flowing over the outer diameter end of a sealing member 9 from a seal space S when oiling from the seal space S formed at the inner periphery of the sealing member 9, oil can be prevented from further spreading to the outer diameter side by the oil repellent action of the oil repellent part P1. Further, the outer peripheral surface 7a2 of the bearing device can be prevented from being contaminated with oil. COPYRIGHT: (C)2008,JPO&INPIT |
