摘要：
A dynamic pressure generation portion is formed on the outer circumferential surface 2a1 of a shaft portion 2a. This allows for forming a bearing member 7 into which a housing and a sleeve-shaped member that were conventionally separately configured due to the machinability of the dynamic pressure generation portion are integrated. The opening at one end of the bearing member 7 is sealed with a cover member 8 integrated with the bearing member 7 or with a separate cover member 8 secured to the bearing member 7.
