Abstract

　継手の構成を大きく変更することなく、トルク伝達効率を向上させる。 　軸方向に延びる複数のトラック溝１１が内球面１０に形成された外輪１２と、外輪１２のトラック溝１１と対をなして軸方向に延びる複数のトラック溝１４が外球面１３に形成された内輪１５と、外輪１２と内輪１５のトラック溝１１，１４間に介在してトルクを伝達する複数のボール１６と、外輪１２の内球面１０と内輪１５の外球面１３との間に介在してボール１６を保持するケージ１７とを備え、外輪１２と内輪１５のトラック溝１１，１４の曲率中心が継手中心に対して等距離だけ軸方向に逆向きにオフセットされ、外輪１２と内輪１５のトラック溝１１，１４で形成されたボールトラックにおけるＰＣＤすきま（２×ｍ）を２５μｍ以上、内輪１５の外球面１３とケージ１７の内球面１９との間の球面すきま（２×ｎ１）を４０μｍ以上、ケージ１７の外球面１８と外輪１２の内球面１０との間の球面すきま（２×ｎ２）を４０μｍ以上とする。
