Abstract
トリポード型等速自在継手（１）は、トラック溝（５）を備える外側継手部材（２）と、半径方向に突出した三つの脚軸（７）を備えたトリポード部材（３）と、トラック溝（５）に挿入されたローラ（１１）と、脚軸（７）に外嵌され、ローラ（１１）を回転自在に支持するインナリング（１２）とを備える。各脚軸（７）の表面に、浸炭焼入れ焼戻しにより硬化層（１６）が形成される。トリポード部材（３）は、炭素含有量が０．２３％～０．４４％の鋼材で形成する。トリポード部材（３）に連結される軸（９）が捩り破断を起こす最小の静的捩りトルクの０．３倍をＴｓトルクとして、６００ＨＶを限界硬さとした硬化層（１６）の有効硬化層深さ（Ｈ）を、Ｔｓトルクを負荷した時の最大せん断応力深さ（Ｚ）以上にする。
