Abstract
【解決手段】本発明による転がり軸受10の保持器付き転動体12は、複数の円筒ころ15と、これら円筒ころ15を収めるポケット16が一定間隔で形成された保持器17とを具え、保持器17の外周面17oには、この保持器17の側端面17sからポケット16へと至る溝18が形成されている。ポケット16側に位置する溝18の端部に対し、保持器17の側端面17s側に位置する溝18の端部が保持器17の回転方向後方に位置するように、溝18が保持器17の幅方向に対して傾斜している。環状をなす外輪14をさらに具え、この外輪14には、その外周面14oから保持器17の外周面17oと対向するその内周面14iへと至る給油孔19が形成されている。
