PROBLEM TO BE SOLVED: To sufficiently secure cultivation space in a greenhouse without increasing a height of the greenhouse to streamline a cultivation work so that construction cost of the greenhouse and installation cost of a curtain opening/closing device are reduced.SOLUTION: An curtain opening/closing device for a greenhouse comprises: a plurality of guide members which are stretched over almost the whole length of the greenhouse adjacent to inner surfaces of arch-shaped members and parallel to a ridge direction; a leading member which is fixed to a drive wire and is moved orthogonal to the guide member in the ridge direction on the guide member by driving of the drive wire; a drive shaft which is disposed along one of gable surfaces of the greenhouse and includes a rotation drum to drive the driving wire; and a curtain member of which tip part is fixed to the leading member and base end part is fixed to a fixing member extended along the inner surface of the arch-shaped member, and which expands/contracts to open/close by movement of the leading member. The curtain member is moved along the inner surface of the arch-shaped member in the greenhouse making a point right under the ridge pole as the maximum height point to maximize cultivation space in the greenhouse. |
