<p>PROBLEM TO BE SOLVED: To provide a dynamic pressure bearing unit that can be thinned and reduced in weight. SOLUTION: This dynamic pressure bearing unit supports a shaft member 2 in a contactless manner with dynamic pressure generated in bearing clearances C1, C2 between the shaft member 2 and a bearing member 4, when the shaft 2 is rotated. A bearing clearance is composed of the first clearance C1 on one side in the axial direction, and the second clearance C2 on the other side, and the first clearance C1 and the second clearance C2 are respectively inclined in reverse with respect to the axial direction.</p> |
