Abstract

　一方向クラッチの組み立て工程の工数を少なくし、部品点数を少なくする。 　外輪１及び内輪２を軸周り回転可能に支持する軸受部５と、前記外輪１及び内輪２の間に配置される複数のスプラグ３と、前記各スプラグ３を保持する保持器４と、前記各スプラグ３を付勢する弾性部材６とから成る一方向クラッチにおいて、前記軸受部５を前記外輪１及び内輪２の軸方向一端にのみ配置し、前記係合子３の軸方向他端側に保持器４で保持された複数の円筒ころ１０を配置した。このようにすれば、軸受部５の一方を省略してもなお、外輪１や内輪２等に作用するラジアル荷重、モーメント荷重に対して一方向クラッチの作動を阻害しないようできるとともに、その部品点数、組み立て工程の工数を削減できる。
