場合には油切れが発生するおそれがある。Oil-impregnated sliding bearings, which use porous sintered metal KffA oil-impregnated as bearing metal, are widely used as bearings for various motors and drive shafts. Such oil-impregnated sliding bearings are normally used without lubrication due to the lubricating oil impregnated in the bearing metal, but if used for a long period of time, there is a risk that oil will run out.

いる。Therefore, in such cases, an oil-impregnated sliding bearing 1 as shown in FIGS. 72 and 13 is used. This oil-impregnated sliding bearing 1 includes a support 1 having a hole having a circular cross section.
1, a cylindrical bearing member 12 fitted into the inner peripheral surface of the hole of the support 11, and an oil-impregnated felt 13 provided in contact with the end surface of the bearing member 12. The bearing member 12 is made of porous sintered metal, and the inside thereof is impregnated with lubricating oil. and,
The lubricating oil pressure is used to lubricate the sliding surface with 41114. Further, the oil-impregnated felt 13 provided in contact with the bearing member 12 contains lubricating oil, and as the lubricating oil of the bearing member 12 is consumed, the lubricating oil is replenished through the contact portion to compensate for the shortage. It is designed to compensate.

There has been a problem in that it has not been possible to adequately meet the recent demand for longer non-lubricated operating times. That is, in the oil-impregnated sliding bearing I, although lubricating oil is supplied by the oil-impregnated felt 13, there is a limit to the amount of oil that the oil-impregnated felt 13 can hold. Further, for example, if an attempt is made to increase the amount of oil retained by increasing the thickness of the oil-impregnated felt 13, there is a disadvantage that the amount of protrusion of the shaft 14 from the bearing increases accordingly.

Furthermore, in the above oil-impregnated sliding bearing 1, there was a problem in that the fibers of the oil-impregnated felt 13 could become entangled in the bearing sliding surface, making it impossible for the shaft 14 to rotate.
