A fluid bearing with an oil circulating hole therein has a bearing housing fixedly
assembled to a stator base having a closed bottom surface; and upper and lower
bearing portions; and a thrust receiving portion to rotatably support a rotating
shaft. An opening oil reservoir is in the bearing housing and a lower oil reservoir
is formed at the lower portion thereof. An intermediate oil reservoir is located
between the upper and lower bearing portions. The oil circulating hole is formed
in parallel with the rotating shaft in order to communicate with the opening oil
reservoir, the intermediate oil reservoir and the lower oil reservoir. A space
is defined at an opening portion which is covered with a cap in order to prevent
oil from leaking.
