摘要 |
To provide a manufacturing method of a dynamic pressure bearing device and a dynamic pressure bearing device to inject a proper amount of lubricating oil to a bearing unit by using a simple process without leaving air bubbles in the bearing unit. The bearing unit is exposed in an atmosphere of reduced pressure such as in a vacuum chamber or the like to evacuate air in a gap between a shaft body and a bearing.
