Description
前記金属環の外縁よりも径方向外側において前記金属環を囲うように突出する円環状の外方部材側堰部が前記芯金に設けられ、前記外方部材側堰部の内周面に潤滑材を保持する外方部材側拡径部が形成されるものである。
図4(b)に示すように、内方部材側堰部9dに受け止められているグリースgrの量が限界量を超えた場合、グリースgrは、内方部材側堰部9dから芯金8の外方部材側堰部8fに向かって流出する(黒塗矢印)。グリースgrは、内方部材側堰部9dによって内方部材側堰部9dの先端と径方向で重複する位置に形成されている外方部材側拡径部8gに案内される。グリースgrは、外方部材側拡径部8gである溝の内部に流入し、保持される。つまり、グリースgrは、内方部材側堰部9dから流出しても外方部材側拡径部8gによって捕獲される。さらに、外方部材側拡径部8gのグリースgrは、外気と接触している外方部材側堰部8fを介して冷却されることで粘度が増大し、外方部材側拡径部8gから流出し難くなる。
以下の実施形態においても同様である。
