Abstract

　潤滑油の循環性に優れ、長期にわたって安定した潤滑性能を発揮することができ、しかも、ころ軸方向長さの延長が可能となって、定格荷重のアップを図ることができる円すいころ軸受を提供する。 　内輪５１と、外輪５２と、内輪５１と外輪５２との間に転動自在に配された複数の円すいころ５３と、円すいころ５３を円周所定間隔に保持する保持器５４とを備え、内輪５１の外径面の大径側にのみ円すいころ５３を案内する鍔部５６を設けた円すいころ軸受である。保持器５４は、大径側環状部６１と、小径側環状部６２と、大径側環状部６１と小径側環状部６２とを連結する柱部６３とを備えた樹脂保持器である。小径側環状部６２の外径端部６２ａを柱部６３の小径側端部６３ａよりも内径側に配置した。
