- 筒状の継手本体と該継手本体の端部開口に挿入される管との間に抜止め用のコマを配置して、該コマを保持するコマ保持部材を継手本体の軸方向外側に向かって移動させることにより、開口端部側が小径となるように継手本体の内面に形成したテーパ面にコマを押し付けて管の抜け出しを阻止するようにした管継手において、
前記コマ保持部材が、リング状ボディと、該リング状ボディからボディ軸方向に延出され且つ周方向に間隔をあけて形成された複数のコマ保持片とを備え、該コマ保持片の先端部分に設けた保持部に前記コマが保持され、
前記継手本体の端部開口の内周面に、前記複数のコマ保持片に対応する位置に複数のスリットが形成され、このスリット内に前記コマ保持片を配置することによりコマ保持部材の回動が阻止されており、
更に、継手本体の開口端面と前記リング状ボディとの間に回動操作環が配置され、該回動操作環にカムが設けられ、回動操作環を回動することによりリング状ボディがカムに乗り上げてコマ保持部材が軸方向外側に向かって移動するように構成されている、管継手。 - 継手本体の端部開口の内周面には、前記複数のスリットの間に凸部が設けられ、該凸部の内径が、コマ保持部材の内径より小であり管外径より大である請求項1に記載の管継手。
- 前記コマ保持部材のコマ保持片は、リング状ボディと保持部との間の距離が微小変動可能なように軸方向に伸縮する弾性を有する請求項1又は2に記載の管継手。
- 前記回動操作環を回動してリング状ボディがカムに乗り上げた位置で互いに係合する係合凹部並びに係合凸部が、回動操作環とコマ保持部材との摺接する面に設けられている請求項1,2又は3に記載の管継手。
