Description
Claims (1)
- リング状の外輪と、前記外輪の内周側に配置されるリング状の内輪と、前記外輪および前記内輪間に配置され円周上等間隔に複数のポケットを有する保持器と、前記ポケットに配置される複数の円すいころとを備え、前記外輪は、内周に前記円すいころが転動する外輪側軌道面を有し、前記内輪は、外周に前記円すいころが転動する内輪側軌道面と、この内輪側軌道面を挟んで小径側に小径側端部と、前記内輪軌道面を挟んで大径側に大径側端部とを有し、前記保持器は、前記ポケットに対し軸方向両側の一方で前記小径側端部に対応する位置に設けられたリング状の第1環状部と、前記ポケットに対し軸方向両側の他方で前記大径側端部に対応する位置に設けられたリング状の第2環状部と、前記ポケットに対し円周方向両側に設けられた柱部とを有し、前記円すいころの回転中心よりも外径側で前記円すいころを前記ポケットに係合させるようにした円すいころ軸受において、
前記内輪は、前記内輪側軌道面および前記小径側端部の間に環状の環状溝を有し、前記保持器は、前記第1環状部から前記環状溝に向けて内径方向に延びる立設部を有し、
前記立設部は、前記第1環状部から前記環状溝に向けて前記円すいころ側へ傾斜した第1傾斜部と、前記第1傾斜部から前記環状溝に向けて前記小径側端部側へ傾斜した第2傾斜部とからなり、前記第1傾斜部の根元で折れ曲がり、かつ、前記第2傾斜部の根元で折れ曲がることにより内径が拡大する向きに撓むことが可能であり、
前記第2傾斜部は、前記内輪の軸方向に前記環状溝に係合可能であることを特徴とする円すいころ軸受。
