PROBLEM TO BE SOLVED: To provide a bearing device having a long lifetime as product capable of establishing good lubrication between a bearing and a shaft. SOLUTION: A conventional bearing formed through injection molding with an electrocast part inserted has involved such a problem that shortage of the lubricating oil occurs due to dispersion or evaporation of the lubricating oil because only a very small quantity of lubricating oil exists in the bearing gaps, to lead to a problem with wear due to sliding of the bearing with the shaft. According to this invention, an oil refilling member to supply oil to bearing gaps is installed on the bearing, which allows maintaining a good lubricating performance, and it is possible to preclude inconvenience due to a poor lubricating performance including noise emission, a wear due to contact sliding of the bearing with the shaft, etc. COPYRIGHT: (C)2007,JPO&INPIT
