PROBLEM TO BE SOLVED: To provide a greenhouse curtain device having a simple structure, reducing gaps caused at the gable surface of a greenhouse to improve sealing properties, temperature-retaining properties and the like inside the greenhouse.SOLUTION: The greenhouse curtain device includes: primary and secondary stick-like members 41, 42 which are pivotally supported by the respective end parts 21c, 22c of primary and secondary leading pipes 21, 22, wherein lower end sides 41b, 42b with their supporting points 21d, 22d interposed, are set up so as to be respectively connected to the tip ends 31c, 32c of the respective gable surface-covering parts 31b, 32b of primary and secondary curtain members 31, 32; and a turn-controlling member 43 turning the primary and secondary stick-like members 41, 42. During a closing directional operation, the lower end sides 41b, 42b respectively turn forward in the closing direction when upper end sides 41a, 42a upper than the supporting points 41d, 42d of the primary and secondary stick-like members 41, 42 come in contact with the turn-controlling member 43, and the respective gable surface-covering parts 31b, 32b are superimposed on each other. |
