本体を他端側に向つて次第に縮径して、該他端を
偏平にすることにより該他端にスリツト状の開口
部を形成し、前記弁本体の内側の圧力が外側より
高くなつた場合に、前記開口部が開いて流体の流
れを許容し、前記弁本体の内側の圧力が外側より
低くなつた場合に、前記開口部が閉じて流体の流
れを阻止するようにした逆止弁において、前記開

とを特徴とする逆止弁。 A cylindrical valve body made of an elastic material with a large opening at one end is gradually reduced in diameter toward the other end, and the other end is flattened to form a slit-shaped opening at the other end. When the pressure inside the valve body becomes higher than the outside, the opening opens to allow fluid flow, and when the pressure inside the valve body becomes lower than the outside, the opening closes. 1. A check valve configured to prevent fluid flow, characterized in that a thin plate made of a material different from the valve body is inserted into the opening.
