Zusammenfassung:	PROBLEM TO BE SOLVED: To improve the reliability of a rolling bearing that is used while being immersed in an ambient fluid.SOLUTION: A rolling bearing includes: an inner race 2; an outer race 4; multiple rolling elements 6 disposed between a raceway surface 2a of the inner race 2 and a raceway surface 4a of the outer race 4; and a holder 8 having a pocket 10 for storing the rolling elements 6. The rolling bearing is used in an environment being immersed in an ambient fluid. A groove 14 is provided at an inner periphery of the holder 8 in a circumferential direction, and a hole 12 which penetrates from the groove 14 to an outer peripheral surface of the holder 8 is provided. 【課題】周囲流体に浸漬された状態で使用される転がり軸受の信頼性を向上させる。【解決手段】転がり軸受は、内輪2と、外輪4と、内輪2の軌道面2aと外輪4の軌道面4aとの間に介在する複数の転動体6と、転動体6を収容するポケット10を有する保持器8とを具備し、周囲流体に浸漬された環境で使用される転がり軸受であって、保持器8の内周に円周方向の溝14を設け、溝14から保持器8の外周面まで貫通した穴12を設けた。【選択図】図1
