CHECK VALVE AND FLUIDITY REPAIR MATERIAL INJECTOR
PROBLEM TO BE SOLVED: To provide a check valve capable of preventing a backflow of a high pressure fluidity repair material by strongly closing a slit while reducing a manufacturing cost by forming the slit by resin molding, and capable of inserting a grease gun or the like into a cylinder body from the outside with a small force.SOLUTION: A check valve comprises a body to be inserted into a cylindrical body. The body has: a slit which opens to a tip end surface of the body; a pressed part which is pressed in the width direction of the slit in contact with an inner peripheral surface of the cylindrical body on a side surface of a tip part of the body in a state in which the body is inserted into the cylindrical body; and a relief part which is a part spaced apart from the inner peripheral surface of the cylindrical body by a predetermined distance on the side surface of the tip part of the body in a state in which the pressed part is in contact with the inner peripheral surface of the cylindrical body. The relief part is arranged so as to intersect the longitudinal direction of the slit on the side surface of the tip part of the body.SELECTED DRAWING: Figure 1
【課題】樹脂成型によりスリットを形成して製造コストを低減しつつ、スリットを強く閉じて高圧の流動性補修材の逆流を防ぐことができ、外側から筒体内へは小さい力でグリスガン等を差し込むことができる逆止弁を提供する。【解決手段】筒体内に挿入される胴体を備えた逆止弁であって、前記胴体が、前記胴体の先端面に開口するスリットと、前記胴体が前記筒体内に挿入された状態で、前記胴体の先端部側面において前記筒体の内側周面と接触して前記スリットの幅方向に押圧される部分である被押圧部と、前記被押圧部が前記筒体の内側周面と接触している状態で、前記胴体の先端部側面において前記筒体の内側周面に対して所定距離離間している部分である逃げ部と、を備え、前記逃げ部が、前記胴体の先端部側面において前記スリットの長さ方向と交差するように配置した。【選択図】図１
