面間に前記合成樹脂製スラストワッシャとほぼ同一直径
を有する金属製スラストワッシャが装着されてなる十字
軸自在継手の構成とした。
作用 十字軸自在継手の使用時、十字軸の軸部の軸方向荷重が
合成樹脂製スラストワッシャに作用しても、合成樹脂製
スラストワッシャの周縁部は金属製スラストワッシャに
より完全に支持された状態のため、研磨逃げ溝に喰い込

ッシャの周縁部は、金属製スラストワッシャにて強固に
支承されているため、軸受ケースの内底面の研磨逃げ溝
に喰い込んで変形したりクラックが生じたりすることが
ない。従って、合成樹脂製スラストワッシャは、十字軸
の軸部端面と軸受ケース内底面間の焼付防止、及び摩耗
防止効果を十分に発揮することができる。
