Abstract
Provided is a fluid bearing device with a hub part having high molding precision and dimensional stability and capable of being produced at low cost. An annular gate () is formed at a portion of a cavity () corresponding to an outer peripheral edge portion of a lower end surface () of a flange part (), and a molten resin (P) is filled into the cavity () through the annular gate () to form a hub part () made of resin. The hub part () molded by the injection molding exhibits a radial resin orientation through an entire periphery thereof. Further, an annular gate trace () is formed at the outer peripheral edge portion of the lower end surface () of the flange part () of the hub part ().
