Description
図1は、本発明の玉軸受の実施の一形態を示す断面図である。この玉軸受1は、内輪2と、この内輪2の径方向外側に設けられている外輪3と、これら内輪2と外輪3との間に介在している複数の玉4と、これら玉4を保持している環状の保持器5とを備えている。この玉軸受1では、内輪2と外輪3との間に形成される環状空間に潤滑剤としてグリースが設けられている。本実施形態において、軸方向とは、玉軸受1の中心線CL(以下、軸受中心線CLという。)に平行な方向も含み、また、径方向とは、軸受中心線CLに直交する方向である。
更に、前記中立状態から保持器5が軸方向一方側に変位すると、ガイド部14が内軌道溝21に対して軸方向から接触することにより、保持器5の位置決めを行うことができる。このように、ガイド部14が内軌道溝21に接触することにより、保持器5の軸方向一方側への変位が規制される。
また、保持器5に過大な変形が生じようとすると、その変形のモードによっては、外対向面部56が玉4に対して接触可能となり、これにより、過大な変形を阻止することができる。
