PROBLEM TO BE SOLVED: To provide a device for smoothly opening and closing a plastic green house. SOLUTION: The objective green house-opening and closing device comprises guide rails 12 that is arranged along the roof of the house, the wheel slider 13 that is slidably mounted on the guide rail 12, motor units 14 connected to the wheel sliders 13 and the sheet 19-winding shafts 18 that are driven by the motor units 14 horizontally arranged on the roof of the house 11. Since the motor units 14 slide along the guide rails 12, the sheet-winding shafts 18 can be smoothly moved along the roof of the house and the sheets 19 are wound up and wound back whereby the house 11 can be smoothly opened and closed. |
