Abstract
A porous bronze and a resin impregnated in pores of the porous bronze formed on a backing metal constitute a bearing At a surface to be brought into contact with a crank shaft porous bronze and resin are sparsely exposed. Ratio of area of exposure of porous bronze at the contact surface is at least 5% and at most 60%. Thus a bearing for a refrigerating compressor having high seizure resistance at the time of boundary lubrication and having small amount of wear caused by sliding as well as a refrigerating compressor employing the same can be obtained.
