（１）玉３とポケット内向との接触部６の接触面積が少
なく、接触部の平均面圧が 嶋く、接触部の摩耗が大きいう （２）玉３とポケット内面との接触面積が小さいことは
、保持器４から玉３の転走 面への自己潤滑剤の供給が減少し、摩 擦抵抗が大となる。
それ故、この発明の目的は、前述し た不具合を解消させるため、保持器の ポケットの形状を改良することにあり、この発明によれ

軸受用保持 器が提案される。
この発明の軸受用保持器は次の如き 効果を有する。
（３）玉とポケット内面との接触面積が増加し、平均面
圧を下げ且つ保持器から玉 の転走面への自己潤滑剤の供給が増大 し、玉との接触面の摩耗を減少させ得 る。
（４）さらに、保持器の軸方向のをり（たとえば、冷却
剤の供給により）、および 保持器のが友つきがなく、玉の接触面 の確保および軸受の振動防止が可能と なる。
（５）保持器のポケツ）ｆｉｌ１面の肉厚が薄くなする
ことかなく、保持器の強度を増澗させ得る。
（６）油Ｓ滑タイプの軸受の場合、玉とポケット内向と
の接触面積の増大により、 油による流体動圧効果が大となり、玉 と保持器側面とｔ−離反させ玉とポケット内面との接触

に〜内竺輪に接触することがない。この丸め、案内面の
焼付を防止 し、使用回転数を上げることができる。
この発明の実施例を添付図面を参照して説明する。
