ABSTRACT:
In an outer ring, a plurality of lubrication oil flow paths which penetrates from an outer circumference surface of the outer ring to an inner circumference surface (in particular, raceway groove) are provided. Opening positions of the each lubrication oil flow paths are made different in a width direction being orthogonal to a rolling direction of a ball. At least one of the lubrication oil flow paths is used as a lubrication oil supply path, and a lubrication oil discharge path is selected from the other lubrication oil flow paths to adjust a range of lubrication oil amount, so that an amount of lubrication oil in the raceway groove is controlled.
