PURPOSE:To obtain a sheet winding apparatus of a greenhouse excellent in simplicity, preventing creases by winding and an eccentric winding and giving no sheet damages by installing a winding drive unit on a vertical frame pipe of a greenhouse and interlockingly installing a winding pipe to an output shaft. CONSTITUTION:This sheet winding apparatus is constructed as follows. A winding drive apparatus M is movably installed on a vertical pipe 1' of a greenhouse and a sheet winding pipe (m) is interlockingly engaged to an output shaft 10' of the winding drive apparatus M. A winding sheet is freely and windably connected to the sheet winding pipe (m) and a winding drum 12 is more preferably interlockingly installed to a drive unit 10 of the winding drive apparatus M. The lower end of a winding wire 13 is freely and windably connected to the winding drum 12, while the upper end of the winding wire 13 is fixed to the vertical pipe 1'. The winding drive apparatus M can be mobile upward by a winding action of the winding drum 12. |
