GREENHOUSE, AND MECHANISM FOR SUPPRESSING FLUTTERING OF VENTILATION FILM

摘要

PROBLEM TO BE SOLVED: To provide a greenhouse so structured as to limit the wind blowing in from the side of a flank face; and to provide a mechanism for suppressing fluttering of a ventilation film. SOLUTION: The greenhouse is provided with a mechanism for suppressing fluttering of a ventilation film having a covering film 80 one edge 81 of which is arranged so as to have no clearance with a flank face 14, and the other edge 82 of which is arranged so as to be superposed on the outer surface of a ventilation film 40. A driving part 60 giving rotatory power while moving following a winding-up axis 50 can be arranged inside the covering film 80. Such mechanism and structure result in limiting the wind blowing in the greenhouse from the side of the flank face so as to suppress fluttering of the ventilation film and wind damage such as falling down of crops when the strong wind blows.
