摘要：
A roller bearing includes an outer ring, an inner ring, and plural rolling elements rollably interposed between mutual raceway surfaces of the outer and inner rings, and is used by fitting an outer diameter surface of the outer ring serving as a fitting surface to a housing serving as a mating member or by fitting an inner diameter surface of the inner ring serving as a fitting surface to a shaft serving as the mating member. The fitting surface is provided with at least one protrusion so that a static torque Thold=Σ(F×r) generated by the protrusion is equal to or greater than a torque Tcreep generated by creep.
