Abstract

自動調心ころ軸受は、円弧形状の内輪部材（３３，３４）を円周方向に複数連ねて形成される内輪（３２）と、内輪（３２）に沿って配置される複数の球面ころと、複数の軌道部材（３３，３４）を連結する締結部材（３７）とを備え、隣接する内輪部材（３３，３４）それぞれの円周方向端面には、互いに対面する位置に隣接する軌道部材（３３，３４）の当接面に沿う方向に突出する一対の凸壁（３３ｂ，３４ｂ）が形成されており、締結部材（３７）は、一対の凸壁（３３ｂ，３４ｂ）を円周方向に跨いで位置するベース部（３７ａ）と、ベース部（３７ａ）の両端部から凸壁（３３ｂ，３４ｂ）の突出方向と逆方向に突出して、一対の凸壁（３３ｂ，３４ｂ）を円周方向の両側から挟持する一対の係止部（３７ｂ，３７ｃ）とを有する。
