PROBLEM TO BE SOLVED: To provide a rolling bearing for suppressing the torsional deformation of a cage during high speed rotation. SOLUTION: The rolling bearing 10 comprises an outer ring 11 having an outer ring raceway surface 11a on the inner peripheral face, an inner ring 12 having an inner ring raceway surface 12a on the outer peripheral face, a plurality of rolling elements 13 rollingly arranged between the outer ring raceway surface 11a and the inner ring raceway surface 12a, and the cage 14 for holding the rolling elements 13 at circumferentially equal spaces. The cage 14 has pocket portions 15 neighboring each other in the circumferential direction for rollingly holding the rolling elements 13, and a pair of pawl portions 16 protruded axially from both circumferential ends on the inner peripheral face of each pocket portion 15. Guide portions 18 for the outer ring 11 are provided on the outer peripheral faces of the pair of pawl portions 16. COPYRIGHT: (C)2008,JPO&INPIT
