To provide an attic ventilation structure capable of smoothly ventilating outside air flowing in through a soffit or a vent layer of an outer wall via a ventilation tower and exhausting it, while preventing warm air leaking from a ceiling from being provided to a roof.SOLUTION: In a building 80 that has an outer wall 10 with a vent layer 11, a roof 20 with a plurality of rafters 23 and a roof board 22, a soffit 25 that connects an end of the roof 20 and the outer wall 10, and a ceiling 30 on an indoor side of the outer wall 10, in a roof ventilation structure 100 for exhausting first outside air that flows in from the soffit 25 and second outside air that flows in from the vent layer 11 via a ventilation tower through an attic space 40 between the ceiling 30 and the roof 20, a lower part of a vertical face material 50 is fixed to an indoor side surface 11a of the vent layer 11 of the outer wall 10, one end of a horizontal face material 60 with a gap between it and the roof board 22 opposite to the roof board 22 is fixed to an upper part of the vertical face material 50, and a ventilation layer 70 extending to the ventilation tower is formed by the roof board 22 and the horizontal face material 60.SELECTED DRAWING: Figure 3
【課題】天井から漏れる暖気が屋根に提供されることを防止しながら、軒天や外壁の通気層を介して流入された外気をスムーズに塔換気に流して排気することのできる、小屋裏換気構造を提供すること。【解決手段】通気層１１を備える外壁１０と、複数の垂木２３と野地板２２とを備える屋根２０と、屋根２０の端部と外壁１０を繋ぐ軒天２５と、外壁１０の屋内側にある天井３０とを有する建物８０において、天井３０と屋根２０の間の小屋裏空間４０を介して、軒天２５から流入する第１外気と通気層１１から流入する第２外気を塔換気を介して排気する、小屋裏換気構造１００において、縦面材５０の下部が外壁１０の通気層１１の屋内側面１１ａに固定され、野地板２２に対向して野地板２２との間に隙間を備えている横面材６０の一端が縦面材５０の上方に固定され、野地板２２と横面材６０とにより、塔換気まで延びる換気層７０が形成されている。【選択図】図３
