To provide an inexpensive movement limiting device that can limit the movement of an upper edge of a door body to a downstream side and an upstream side without impairing the advantages of a hinge device having a double hinge structure, prevents a connecting metal fitting from rotating excessively, and does not require position adjustment.SOLUTION: A hinge device 4 in an upper hinge type flap gate comprises a door body side hanging metal fitting 6, a door stop side hanging metal fitting 8, and a connecting metal fitting 9. The connecting metal fitting 9 is an L-shaped metal plate, and an upper shaft support portion 10 is arranged at a corner of the connecting metal fitting 9, and a lower shaft support portion 11 is arranged at one end. Then, the upper shaft support portion 10 and the lower shaft support portion 11 are pivotally supported by the door stop side hanging metal fitting 8 and the door body side hanging metal fitting 6, respectively. A minute gap is formed between a tip surface 12 and a base plate 13 in a state where a water channel outlet is closed by a door body 2.SELECTED DRAWING: Figure 3
【課題】ダブルヒンジ構造のヒンジ装置の長所を損なわずに、扉体の上縁部の下流側及び上流側への動きを制限できるようにすること及び接続金具が過度に回動しないようにするための移動制限装置を安価に提供するとともに、移動制限装置の位置調整を不要にする。【解決手段】上ヒンジ方式のフラップゲートにおけるヒンジ装置４であって、扉体側吊金具６、戸当側吊金具８及び接続金具９から構成され、接続金具９がＬ字型の金属板であり、接続金具９の角部に上部軸支部１０が配置され、一端部に下部軸支部１１が配置されている。そして、戸当側吊金具８及び扉体側吊金具６に、それぞれ上部軸支部１０及び下部軸支部１１を軸支させ、扉体２によって水路出口が閉鎖されている状態において、先端面１２とベース板１３との間に微小な隙間が形成される。【選択図】図３
