摘要：PROBLEM TO BE SOLVED: To provide a fluid dynamic-pressure bearing simplified in fitting of a thrust plate in a shaft central part. SOLUTION: This fluid dynamic-pressure bearing has a fixing element 12 to be inserted into a hole 11, which is formed in the shaft 4 in the axial direction, to fix the thrust plate 9. Outside diameter of the fixing element 12 is formed larger than the minimum inside diameter of the hole 11. The fixing element 12 enlarges the shaft at an insert position thereof, and generates the pushing force in the radial direction to fix the thrust plate 9 to the predetermined position of the shaft 4. On the other hand, the hole 11 is extended from one end of the shaft 4 provided outside of a bearing system to, at least, near the position for arrangement of the thrust plate 9, and formed to be closed at a lower end thereof.
