PROBLEM TO BE SOLVED: To provide a rolling bearing that can be easily assembled and be reduced in the number of assembling steps.SOLUTION: A rolling bearing 1 includes an inner ring 2, an outer ring 3, a plurality of rollers 4 arranged between both the rings 2, 3, and an annular holder 5 that holds the rollers. The holder 5 is formed of a plurality of holder segments 6 having a circular-arc shape and arranged in a circular pattern. Each holder segment 6 includes rims 71, 72 opposed to each other and separated from each other at a predetermined interval, and a plurality of cage columns 8 that extend from one of the rims 71, 72 to the other rim and that define pockets for receiving the rollers 4 and arranged in the circumferential direction. Multiple pairs of hook portions 101, 102, between which the inner ring 2 is sandwiched, are protrudingly formed in the rims 71, 72 at predetermined intervals along the circumferential direction. Distal ends of the hook portions 101, 102 are relatively rotatably locked with annular grooves 21, 22 formed in end portions of the inner ring 2. |
