To provide a drain structure that is more excellent in mounting property than before and has no fear of being blown off by the strong wind.SOLUTION: A drain structure comprises: a drain cap 9 of a water passing structure covering a drain port 4; a spring member 13 extended from the inside to the outside, squeezed and inserted into the drain port 4, restored by its own elastic force and brought into pressure contact with an inner periphery of the drain port 4; and anchors 14 provided at a plurality of places of an outer edge part of the drain port 4 so as to prevent the extraction from the drain port 4 by being hooked to the spring member. In the drain structure 17 in which the spring member 13 has a slit 15 extending in a longitudinal direction and each anchor 14 is formed so as to form a hook shape downward with a width fitting in the width, each spring member 13 is formed into a wire frame shape by an elastic wire material and its gap part forms the slit 15, and a tip part of each spring member 13 is made to be a bent part 13a.SELECTED DRAWING: Figure 1
【課題】従来よりも取り付け性が良好で且つ強風により吹き飛ばされる心配の無いドレン構造を提供する。【解決手段】排水口４を覆う通水構造のドレンキャップ９と、その内側から外側へ張り出し且つ排水口４の内部に窄めて挿入されてから自身の弾性力により復元して排水口４の内部周囲に圧接するばね部材１３と、これに掛止して排水口４からの抜脱を阻止するよう排水口４の外縁部の複数箇所に設けられたアンカー１４とを備え、ばね部材１３が長手方向に延在するスリット１５を有し、その幅内に収まる幅で且つ下方向きに鉤形を成すように各アンカー１４が形成されたドレン構造１７に関し、各ばね部材１３を弾性線材によりワイヤーフレーム状に形作り且つその間隙部分がスリット１５を成すように構成し、各ばね部材１３の先端部を曲折部１３ａとする。【選択図】図１
