PROBLEM TO BE SOLVED: To provide an eaves ventilation structure having a protected connection between a ventilation member and an external wall member and therefore improved fire resistance.SOLUTION: A ventilation member 15 and an external wall member 35 that constitute an eaves ventilation structure 11 include an extended part 20 and a receiving part 39, respectively, and the extended part 20 is engaged slidably in a horizontal direction with the receiving part 39. A thermal-expansion sealing 32 is filled in a space (S) at a connection between the ventilation member 15 and the external wall member 35, the space being formed by an eaves part 19, the extended part 20, and a part 38 facing the eaves, and having an inverted U-shape cross-section in a shorter side direction of a roof material. The configuration allows the connection between the ventilation member 15 and the external wall member 35 to be protected even when a fire breaks out in a house provided with the eaves ventilation structure 11, by the thermal-expansion sealing 32 expanded by the heat.
【課題】 通気部材と外壁部材との接合部分が保護され、耐火性が向上した軒先換気構造体を提供する。【解決手段】 軒先換気構造体１１を構成する通気部材１５は延出部２０を、外壁部材３５は受け部３９をそれぞれ含んでおり、延出部２０は、受け部３９に対して水平方向にスライド自在に係合している。又、通気部材１５と外壁部材３５との接合部分であって、軒先部１９、延出部２０及び軒先対向部３８により形成される、屋根材の短手方向の断面が逆Ｕ字形状のスペース（Ｓ１）には、熱膨張シーリング３２が充填されている。このような構成とすることで、軒先換気構造体１１を備える家屋に火災等が発生しても、その熱によって膨張した熱膨張シーリング３２によって、通気部材１５と外壁部材３５との接合部分は保護される。【選択図】 図１７
