PROBLEM TO BE SOLVED: To provide a filler injection device with a simple and compact structure that offers excellent workability, high filler injection pressure, and greater cost-effectiveness compared to conventional products.SOLUTION: A filler injection device comprises a pressurizing part having an expandable inner space, a first communication passage connecting an inside and an outside of the pressurizing part, a second communication passage connecting the inside and the outside of the pressurizing part, and a backflow prevention structure that prevents outflow of a filler from inside the pressurizing part to outside, while allowing the filler to be injected from outside the pressurizing part to inside. The pressurizing part is formed by unifying two plate-form elastic members in a ring-form. The filler pressurized and injected into the inner space through the first communication passage is not discharged from the first communication passage, due to the backflow prevention structure, and is instead discharged from the second communication passage as the inner space is pressurized by the pressurizing part.
【課題】シンプル且つコンパクトな構造を有し、施工性が良好であり、充填材の注入圧力において優れ、コスト面でも従来品に対して優位性のある注入器具を実現する。【解決手段】膨縮自在の内部空間を有する加圧部と、前記加圧部の内外を連通する第１連通路と、前記加圧部の内外を連通する第２連通路と、前記第１連通路において前記加圧部の外部から内部への充填材の注入を許容しつつ前記加圧部の内部から外部への充填材の流出を防止する逆流防止構造と、を備え、前記加圧部は、２枚の板状弾性部材をリング状に一体化して形成され、前記第１連通路を通して前記内部空間に加圧注入された充填材は、前記逆流防止構造により前記第１連通路からは吐出されず、前記加圧部による前記内部空間に対する加圧により前記第２連通路から吐出されることを特徴とする充填材注入器。【選択図】図２０
