PROBLEM TO BE SOLVED: To provide a rolling bearing capable of effectively preventing the generation of unusual noise. SOLUTION: The rolling bearing comprises an outer ring 26 having an outer peripheral raceway surface 27 and an inner ring 36 to relatively rotate with respect to the outer ring 26 on the center axis and, having an inner peripheral raceway surface 37 facing the outer peripheral raceway surface 27, and a plurality of rolling elements 41 which move around the sun, on the center axis while rotating on its axis, and which are arranged in a state that the rolling elements are depressed by the outer peripheral raceway surface 27 and the inner peripheral raceway surface 37 between the outer ring 26 and the inner ring 36. At least either of the outer peripheral raceway surface 27 and the inner peripheral raceway surface 37 has a different profile from other phases in a predetermined phase around the central axis. An attitude of each rolling element 41 changes at each predetermined phase. COPYRIGHT: (C)2007,JPO&INPIT
