Claims (1)
- 両端に筒状の流入口と流出口をそれぞれ形成するとともに前記流入口と流出口との間に軸線方向に所定長さを有する前記流入口よりも大径の内径を有する筒状の弁座が形成されたケース体と、外径が前記弁座の内径よりも僅かに小径で且つ前記流入口の内径よりも大径で前記弁座の軸線方向に移動可能に配置されたディスク状の弁体と、前記弁座の流出口と前記弁体との間に配置される弁体の支持部材(リテーナ)とからなり、前記支持部材(
リテーナ)が前記流出口と弁座との間に形成された円形の溝条に嵌挿される中央に流出窓を形成した円板状の台座と前記台座の前記中央に形成された流出窓の開口縁において弁体方向へ前記弁体の支持片が突設され、前記弁体を支持する支持部材(リテーナ)の前記各支持片が頂部に少なくとも台座の半径方向に向けて水平となる直線状または面状の支持部を有している逆止弁において、前記支持部材(リテーナ)を板状部材から一体に形成する際に、支持片を中心点に向けた方向に交差する方向に向くように立ち上げることで、各支持片が頂部に少なくとも台座の半径方向に向けて水平となる直線状または面状の支持部を有していることを特徴とする逆止弁。
