ABSTRACT:
It is an object of the invention to provide an inexpensive and high-quality fluid bearing which improves the workability in assembly or coupling of a shaft and a rotator. In order to achieve this object, a fluid bearing according to the invention includes a rotating shaft, a bearing member for rotatably supporting the rotating shaft, and first and second fluid film formation mechanisms arranged at positions near a central portion of the rotating shaft along its longitudinal direction. The first fluid film formation mechanism forms a fluid film between the rotating shaft and the bearing member while the rotating shaft rotates in a first direction. The second fluid film formation mechanism forms a fluid film between the rotating shaft and the bearing member while the rotating shaft rotates in a second direction opposite to the first direction.
