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. |
