Claims (3)
- 内輪と、外輪と、複数の転動体と、前記内輪および前記外輪の間で前記転動体を保持するための保持器とを有する転がり軸受であって、
前記保持器が、環状の基部と、前記基部から軸方向に延びる複数の台座部であって、前記基部の円周方向に沿って配列された複数の台座部と、前記各台座部から軸方向にさらに延びるように前記台座部の円周方向の両側に設けられた2つの爪部と、前記複数の転動体を保持する複数のポケット部であって、前記各ポケット部が、隣接する前記台座部の間、および隣接する前記台座部の互いに向き合う前記爪部の間に形成される内面を含むポケット部とを有する転がり軸受において、
前記台座部が、前記基部の内径面より内径の大きい内径面を有し、また前記転動体のピッチ円直径が、前記台座部の前記内径面の内径よりも大きいことを特徴とする転がり軸受。 - 前記基部は、前記台座部と軸方向反対側に底面を有し、前記保持器が、前記底面と前記台座部の前記内径面との間で貫通する孔部をさらに有することを特徴とする請求項1に記載の転がり軸受。
- 前記基部は、前記台座部と軸方向反対側に底面を有し、前記保持器が、前記底面から前記台座部の内部まで延びる止まり孔をさらに有することを特徴とする請求項1に記載の転がり軸受。
