- 同一軸心のまわりに回転する入力側部材と出力側部材との間に、入力側部材の回転を僅かな角度遅れをもって出力側部材に伝達するトルク伝達手段を設け、内周側または外周側に円筒面を有する固定部材を、その円筒面が前記出力側部材の外周面または内周面と対向するように配して、前記出力側部材の所定の位置に、前記固定部材の円筒面との間に周方向で次第に狭小となる楔形空間を形成するカム面を設け、前記出力側部材と固定部材との間に前記入力側部材に連結された保持器の柱部を挿入するとともに、前記各楔形空間にそれぞれ転動体を配し、これらの各転動体間の所定の箇所に弾性部材を組み込んで各転動体を前記楔形空間の狭小部に押し込み、前記入力側部材が回転したときに、入力側部材と一体に回転する保持器の柱部が弾性部材の弾力に抗して転動体を押すことにより出力側部材へのトルク伝達が行われるようにした逆入力防止クラッチにおいて、前記出力側部材が、前記入力側部材と同一の軸心のまわりに回転可能に保持される出力軸と、前記カム面を有するカム部材とを別体に形成して、前記出力軸にカム部材を凹凸嵌合により一体回転可能に連結したものであり、前記出力軸にフランジ部を設け、このフランジ部を軸方向両側から挟み込むフランジ拘束部を前記固定部材に設けるとともに、前記カム部材と出力軸の凹凸嵌合部に両部材の径方向移動を可能とする隙間を設け、使用時には前記弾性部材が前記各転動体を前記楔形空間の狭小部に押し込むことによってカム部材を前記固定部材の円筒面と同心の位置に移動させるようにしたことを特徴とする逆入力防止クラッチ。
- 前記各転動体が、前記保持器の柱部と弾性部材との間に複数個ずつ互いに当接するように配されていることを特徴とする請求項1に記載の逆入力防止クラッチ。
- 前記出力側部材の出力軸とカム部材の少なくとも一方を、焼結金属、鍛造された金属、プラスチックのいずれかで形成したことを特徴とする請求項1または2に記載の逆入力防止クラッチ。
