To provide a water leakage preventive drain preventing water leakage by not circulating water toward a joint face between a hole portion and a drain.SOLUTION: There is provided a water leakage preventive drain 2 comprising: tubular drain bodies 21,23; and a packing provided on an outside face of the drain bodies. The packing may be made of a water expansive sealing member 22, to provide a water leakage preventive drain 2 comprising a water supply hole 11a supplying water in the drain body 21 toward the water expansive sealing member. Specifically, it is effective to provide the water expansive sealing member 22 at a tip of a bent portion 23b.SELECTED DRAWING: Figure 2
【課題】孔部とドレンとの接合面に向けての通水をなくして漏水を防止する漏水防止型ドレンを提供すること。【解決手段】管状のドレン本体２１、２３と、ドレン本体の外側面に設けられたパッキンとを備える漏水防止型ドレン２を提供する。パッキンを水膨張性シーリング部材２２とし、ドレン本体内２１の水を水膨張性シーリング部材に向けて送水する送水孔１１ａを備える漏水防止型ドレン２としてもよい。特に、湾曲部２３ｂの先端に水膨張性シーリング部材２２を設けると効果的である。【選択図】図２
