LOUVER DOOR
PROBLEM TO BE SOLVED: To provide a louver door that can prevent blades of a blade unit from being curved and deformed toward the outdoor side due to negative pressure.SOLUTION: An internal surface near to an indoor side of a vertical frame 2a (blade unit connection frame material) of a frame body 2 is connected with an external surface near to an indoor side of a vertical attachment 4 (attachment) of a blade unit 3 by using a connection mechanism 6. A projection 40 is provided toward the internal surface of the vertical frame 2a at the internal surface near to the outdoor side of the vertical attachment 4. A gap between the projection 40 and the internal surface of the vertical frame 2a is made smaller than the gap between the internal surface of the vertical frame 2a and the outer side surface of the vertical attachment 4. Thereby, the projection 40 decreases the deformation of the vertical attachment 4, and prevents a blade 5 of the blade unit 3 from being curved and deformed toward the outdoor side due to a negative pressure.
【課題】羽根ユニットの羽根が負圧により室外側に向けて湾曲変形することを抑制できるガラリ戸とする。【解決手段】枠体２の縦枠２ａ（羽根ユニット連結枠材）の内側面の室内側寄りと羽根ユニット３の縦のアタッチメント４（アタッチメント）の外側面の室内側寄りを連結機構６で連結し、縦のアタッチメント４の内側面の室外側寄りに突部４０を縦枠２ａの内側面に向けて設け、突部４０と縦枠２ａの内側面との間の隙間を、縦枠２ａの内側面と縦のアタッチメント４の外側面との間の隙間よりも小さくすることで、突部４０で縦のアタッチメント４の変形を減少して羽根ユニット３の羽根５が負圧により室外側に向けて湾曲変形することを抑制する。【選択図】図４
