Abstract

　本発明は、高強度であり且つ外側継手部材のトラック溝の開口端部での焼入れによる変形を抑制可能な等速自在継手を提供する。本発明では、外側継手部材のカップ部１ａにおけるトラック溝１ｄが高周波焼入れによる硬化層８ａを有するアンダーカットフリー型の等速自在継手において、逃げ面１ｆにおけるトラック溝１ｄの溝底ｃを起点として開口端面１ｅを軸方向に突出量ｔで突出させた。ここで前記突出量ｔは、トルク伝達用ボールの直径をｄとした場合に、ｔ＝０．０３７ｄ～０．１８５ｄの関係を満たす。突出部１ｉにおける開口端面１ｅ及び開口端面１ｅに連続するカップ部１ａの外周面１ｊが、焼入れ硬化されていない非硬化層を有する。
