ROLLING BEARING

PROBLEM TO BE SOLVED: To provide a rolling bearing capable of preventing a roller from falling out to the outside of the bearing even when skew occurs at the roller.SOLUTION: A rolling bearing 1 includes: an outer ring 11 formed with an outer raceway surface 11a on its inner periphery; an inner shaft 12 formed with an inner raceway surface 12a on its outer periphery and arranged coaxially with the outer ring 11; a plurality of cylindrical rollers 13 interposed between the outer race surface 11a and the inner raceway surface 12a; and a holder 15 for an annular roller configured to hold the plurality of cylindrical rollers 13. Into the inner ring 12, a cylindrical sleeve 19 with which an end surface 13a on one side in an axial direction of the cylindrical roller 13 can contact is externally fitted.SELECTED DRAWING: Figure 2 【課題】ころにスキューが発生しても、ころが軸受外部に飛び出すのを防止することができる転がり軸受を提供する。【解決手段】転がり軸受１は、内周に外軌道面１１ａが形成されている外輪１１、外周に内軌道面１２ａが形成され外輪１１と同軸に配置されている内軸１２、外軌道面１１ａと内軌道面１２ａとの間に介在する複数の円筒ころ１３、及び、複数の円筒ころ１３を保持する環状のころ用保持器１５を備えている。内軸１２には、円筒ころ１３の軸方向一方側の端面１３ａが当接し得る円筒状のスリーブ１９が外嵌されている。【選択図】図２
