ABSTRACT:
Oil retaining bearing members 2a and 2b for supporting a rotative shaft 1 are arranged in a bearing housing 7 with an interval. The bearing housing 7 has a bottom portion, one end being opened and another end being closed. A porous spacer 3 for supplying a lubrication oil is closely inserted between the oil retaining bearings 2a and 2b. An oil thrower 8 is arranged at an upper portion of the bearing housing 7 and a thrust bearing 5 is arranged at a lower portion. The open end of the bearing housing 7 is arranged on the upper portion and the another end of the bearing housing 7 is arranged on the lower portion of the bearing housing 7, and state a lubrication oil 4a is enclosed in the housing to immerse a part of the porous spacer 3 to some degree. The pore diameter of the porous spacer 3 is larger than that of the oil retaining bearings 2a and 2b. By utilizing capillary tube action in by the porous spacer 3, the lubrication oil 4a is supplied to the oil retaining bearing 2a. Accordingly, an oil retaining bearing unit having an excellent performance and a superior mass productivity and a motor having a long service life and a high reliability using the oil retaining bearing unit can be provided.
