VENTILATION STRUCTURE AND BUILDING

摘要

PROBLEM TO BE SOLVED: To provide a ventilation structure excellent not only in ventilation performance but also in weathering performance and capable of being applied even under various structural conditions.SOLUTION: A flexible sheet 15 is provided within a ventilation path 4 that connects an attic space 2 as a ventilation space of a building 1 and ventilation holes E1 and E2 for communicating the attic space 2 with the outside. When air under wind pressure equal to or higher than predetermined wind pressure flows in from the ventilation holes E1 and E2, the sheet 15 is bent to narrow or close the ventilation path 4 and suppress or inhibit inflow of the air into the attic space 2.
