PROBLEM TO BE SOLVED: To provide a fluid bearing device capable of being reduced in size and thickness, and further having lubricating oil surely prevented from leaking. SOLUTION: A sealing space is formed in the outer diameter region of a radial bearing face, and the sealing space and the radial bearing face are superposed in the radial direction. Thereby, the space in the radial direction required by the bearing device is prevented from increasing in volume by providing the sealing space, the fluid bearing device can reduced in size and thickness with keeping the required volume of the sealing space. In addition, because the sealing space is formed only in one site, leakage of the lubricating oil filled in the interior of the bearing is surely avoided as compared with the case of forming the sealing space in a plurality of sites.
