PROBLEM TO BE SOLVED: To provide a rolling bearing which reduces friction caused between a holder and a guide surface of a bearing ring and prevents failures, such as smearing caused by heat generation and insufficient lubrication, thereby achieving long bearing life.SOLUTION: A rolling bearing includes: an outer ring 2 having an outer ring raceway 2a; an inner ring 3 having an inner ring raceway 3a; multiple rolling elements 4 disposed between the outer ring raceway 2a and the inner ring raceway 3a; and a holder 6 which holds the multiple rolling elements 4. A first guide part 3g having a guide surface 3b for guiding the holder 6 is formed at least one of the outer ring 2 and the inner ring 3, a second guide part 6g having a guided surface 6e facing the guide surface 3b is formed at the holder 6, and multiple guide rolling elements 5 are provided between the first guide part 3g and the second guide part 6g. |
