<P>PROBLEM TO BE SOLVED: To provide a greenhouse for cultivation having winders for opening/closing outer linings and inner linings, prevented from the operation failure of the winders and the deformation and damage of winding shafts due to freezing of water accumulated near the winders. <P>SOLUTION: The greenhouse for cultivation includes skeletons (1, 1a); the outer linings (2, 2a, 2b) made of synthetic resin films or sheets spread on the skeletons (1, 1a); and the winders (4, 4a, 4b, 4c, 4d) having the winding shafts (40) and winding or delivering the outer linings (2, 2a, 2b) while the winding shafts (40) themselves move on or along the skeletons (1, 1a) when opening/closing the outer linings (2, 2a, 2b). The stop positions of the winders (4, 4a, 4b, 4c, 4d) are provided with the required number of water percolating holes (21) for discharging rainwater or dew condensate accumulated in recesses formed between the spread outer linings (2, 2a, 2b) and the wound outer linings (2, 2a, 2b) in the roll state or the winding shafts (40). <P>COPYRIGHT: (C)2013,JPO&INPIT |
