Abstract: PROBLEM TO BE SOLVED: To provide a bearing generating no black corrosive object under a high temperature oil environment and having a superior wear-resistant property, in a turbo-type supercharger for an internal combustion engine. SOLUTION: Copper alloy materials having major components such as Cu, Zn, Al, Mn, and Si are employed as bearing materials 10 and 11 of the supercharger, and the extending direction of an Mn-Si series compound crystallized in the alloy material is set in the axial direction of a rotational axis for a radial bearing, and also in the perpendicular direction of the rotational axis for a thrust bearing.
