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.

摘要： The present invention provides a fluid dynamic bearing device having high durability and capable of being produced at low cost. In the fluid dynamic bearing device, a housing (7) and a disc hub (3) are resin molded parts, and a thrust bearing gap is formed between an upper end surface (7d) of the housing (7) and a lower end surface (3e) of the disc hub (3). In this case, the surfaces (7d, 3e) function as sliding portions (P) temporarily in sliding contact with each other during operation of the bearing. A diameter of PAN-based carbon fibers blended as reinforcement fibers in the resin housing (7) is 12 μm or less, and the blending amount is within a range of 5 to 20 vol %, thereby making it possible to prevent occurrence of flaws and wear in the sliding portions (P).
