SEAL STRUCTURE
PROBLEM TO BE SOLVED: To provide a seal structure capable of securing high water tightness even in a case of being exposed to steam.SOLUTION: A seal part 14 configured to seal a space part between an open hole 12 formed on an outer peripheral wall 11 of a building and a pipe 13 inserted into the open hole 12, includes: a filler seal material 21 charged between the open hole 12 and the pipe 13, and having a water tightness; a flexible member 23 arranged on an outdoor side in a penetration direction of the open hole 12 in the filler seal material 21, and having flexibility; and a first stream shielding member 24 arranged on the outdoor side in the penetration direction of the open hole 12 in the flexible member 23, and having a steam impermeability.SELECTED DRAWING: Figure 1
【課題】シール構造において、水蒸気に暴露されても高い水密性を確保することができる。【解決手段】建屋の外壁１１に形成された貫通孔１２とこの貫通孔１２に挿通された配管１３との空間部を密閉するシール部１４は、貫通孔１２と配管１３との間に充填されて水密性を有する充填シール材２１と、充填シール材２１における貫通孔１２の貫通方向の屋外側に配置されて伸縮性を有する伸縮性部材２３と、伸縮性部材２３における貫通孔１２の貫通方向の屋外側に配置されて水蒸気不透過性を有する第１水蒸気遮蔽部材２４とを備える。【選択図】図１
