Description
前記保持器は、大径側環状部と、小径側環状部と、大径側環状部と小径側環状部とを連結する柱部とを備えた樹脂保持器であり、前記大径側環状部の外径面を柱部の外面と連続した段差を有さない円筒面とするとともに、前記柱部は、大径側環状部の小径側環状部対向面と小径側環状部の大径側環状部対向面とを連結し、かつ、前記小径側環状部の外径端部を前記柱部の小径側端部よりも内径側に配置して、潤滑油の流路を確保し、前記大径側環状部に引っ掛け部を設け、引っ掛け部は矩形平板形状体からなり、内輪と円すいころと保持器が組立状態を保てるような引っ掛かりが内輪の鍔部に対してあり、
鍔部の内輪の大径側端面に切欠部を設け、保持器が軸中心に対し中立状態では、引っ掛け部の内径端部がこの切欠部に遊嵌状に嵌合して、引っ掛け部が鍔部に非接触であり、運転中には鍔部に非接触もしくは、鍔部に接触する場合は、引っ掛け部の内径端と鍔部の切欠部の底面が接触状態となるように、切欠部の切欠寸法は、引っ掛け部の内径端と切欠部の底面との許容されるべき相対的接近量と、引っ掛け部の内面と切欠部の径方向切欠面との許容されるべき相互接近量とによって設定されるものである。
