To provide a dynamic-pressure bearing arrangement capable of assuring bonding strength and bending strength and furthermore rigidity of a dynamic-pressure bearing by assuring long enough for bonding length between each component.

The dynamic-pressure bearing arrangement composes a radial dynamic-pressure bearing part 3 in a clearance between the inner peripheral surface of a sleeve 2 and the outer peripheral surface of a shaft member 1 and composes a thrust dynamic-pressure bearing part 4 in clearance between the axial one end of the sleeve 2 and the opposite surface of the shaft member 1 opposed to the one end and composes a capillary tube sealing part 45 in a clearance between the sleeve 2 and the shaft member 1 opposed to the sleeve 2. A lubricant fluid is continuously filled into the radial dynamic-pressure bearing part 3, the thrust dynamic-pressure bearing part 4 and the capillary tube sealing part 45 without being blocked and forms gas-liquid interface with outside air only within the capillary tube sealing part 45.
