PROBLEM TO BE SOLVED: To provide a fluid bearing device which is capable of reliably eliminating dust generation attributable to a structure for preventing detachment or side deviation of a shaft, or any wear and seizure caused during the low-speed rotation, and excellent in simplicity and maintainability. SOLUTION: The fluid bearing device in which a shaft 15 of a rotating body 1 is supported by a bearing surface 28 in a non-contact manner with fluid S fed between the bearing surface 28 and the shaft 15 from a fluid feed means 3 has an injection unit 29 for preventing side deviation which is provided facing a side surface 11 across the axis of the rotating body 1 and connected to the fluid feed means 3 so that the fluid S fed from the fluid feed means 3 is injected from the injection unit 29 to keep the distance between a bearing body 2 and the rotating body 1.
