    摘要: A fluid dynamic pressure bearing device includes a first capillary seal (50) formed between an outer circumferential surface of a bearing member 20 and an internal circumferential surface of a seal member (30). A second capillary seal portion (60) is formed between an outer circumferential surface of a shaft member (10) and a protrusion hole (31) of the seal member (30). A ventilation hole (32a) is formed in a substantially intermediate portion of a side wall of the seal member. A lubricant holding gap (73) is formed between an inner surface of a top wall (31) of the seal member (30) and the upper end surface of the bearing member (20). Leakage of lubricant (80) is suppressed by action of the capillary seal portions (50, 60), and the liquid surface is positioned in the first capillary seal portion (50) above the ventilation hole (32a), whereby extra lubricant (80) is filled in the first capillary seal portion (50) and the lubricant holding gap (73).
