Abstract
A gap width out of the radial bearing gap is axially differed; a narrow width part which has a relatively smaller gap width in the radial bearing gap is arranged on the side relatively closer to a barycentric position of the rotating body, and a wide width part which has a relatively larger gap width in the radial bearing gap is arranged on a side relatively distant from the barycentric position of the rotating body; and a region facing at least the radial bearing gap of the bearing member is formed to an electroformed part made of deposited metal.
