Abstract:
A method for fabricating a fluid bearing device, wherein said fluid bearing device includes a sleeve having a bearing hole, a shaft inserted in said bearing hole, a lubricating fluid interposed in a clearance between said sleeve and said shaft and capillary seal portions formed in opening portions of said bearing hole and for holding said lubricating fluid, and said shaft and said sleeve supported by dynamic pressure of said lubricating fluid so as to be rotatable relative to each other, the method comprising the steps of:scattering a surplus of said lubricating fluid in said clearance by centrifugal force; and holding said lubricating fluid in a constant quantity by said capillary seal portions, wherein a rotational speed for generating said centrifugal force is higher than a maximum working rotational speed of said fluid bearing device.
