To suppress a contact load of a roller and a raceway surface from rapidly changing and reducing vibration occurring due to a rapid change in the contact load when the roller passes a divided part of the raceway surface of a race.
In a cage 10 of the rolling bearing, pocket parts 12, 13 for rollably holding the roller 11 are formed in a plurality of numbers with a predetermined space in between along the circumferential direction, and in two rows along the axial direction, with both sides in the axial direction (both right and left sides in the figure) as a closed opening. Each row of the pocket parts 12, 13 is arranged so that phase is shifted by a predetermined angle in the circumferential direction so that they are alternately displaced in the circumferential direction.
