To provide drain structure that has better mountability than a conventional one and no fear of being blown off by strong wind.SOLUTION: Drain structure comprises: a drain cap 12 of water-conducting structure for covering an exhaust port 4; plate spring members 13 that overhang downward from the inside of the drain cap 12 and that narrow and insert it inside the exhaust port 4 to be expanded by own elastic force and to closely contact inside a drain pipe 3 just below the exhaust port 4; and an anchor 14 provided at an outer marginal part of the exhaust port 4 so as to be prevented from being drawn from the exhaust port 4 by being locked on the plate spring member 13. The anchor 14 is formed so as to make slits 18 extending along the longitudinal direction on the plate spring member 13 and form a width to accommodate the same within the width of the slit 18 and a downward hook shape.SELECTED DRAWING: Figure 5
【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１２と、該ドレンキャップ１２の内側から下方に張り出し且つ前記排水口４の内部に窄めて挿入されてから自身の弾性力により広がって前記排水口４直下の排水管３内側に圧接する板ばね部材１３と、該板ばね部材１３に掛止して前記排水口４からの抜脱を阻止するよう前記排水口４の外縁部に設けられたアンカー１４とを備え、前記板ばね部材１３に長手方向に延在するスリット１８を形成し、該スリット１８の幅内に収まる幅で且つ下方向きに鉤形を成すように前記アンカー１４を形成する。【選択図】図５
