Zusammenfassung:To minimize deformation of horns of a retainer due to centrifugal force, and to prevent degradation of strength of the horns.SOLUTION: A rolling bearing 10 includes an inner ring 11, an outer ring 12, a plurality of balls 13, and an annular retainer 14. The retainer 14 has an annular body 31 positioned at an axial one side with respect to the balls 13, and a plurality of horns 32 extending from the annular body 31 to the axial other side. The horn 32 has a defective part 37 from an axial one side to the other side of the horn 32 in a manner of being opened to the axial other side and a radial direction, and the horn 32 includes a pair of horn bodies 38, 38 kept into contact with the ball 13 at both sides in the circumferential direction of the defective part 37. A stiffening rib 40 is disposed between the pair of horn bodies 38, 38.SELECTED DRAWING: Figure 2 【課題】遠心力によって保持器のつのが変形し難くなると共に、つのの強度低下を防ぐ。【解決手段】転がり軸受10は、内輪11と、外輪12と、複数の玉13と、環状の保持器14とを備える。保持器14は、玉13よりも軸方向一方に位置する環状体31と、環状体31から軸方向他方に延びて設けられている複数のつの32とを有する。つの32には、つの32の軸方向の一方側から他方側にわたって軸方向他方及び径方向に開口する欠損部37が形成されていて、つの32は、欠損部37の周方向についての両側に玉13と接触する一対のつの本体38,38を備える。一対のつの本体38,38の間に補剛リブ40が設けられている。【選択図】 図2
