PURPOSE:To provide roll curtain equipment for preventing a film winding shaft from performing a meandering or a right and left ununiform movement. CONSTITUTION:This roll curtain equipment is equipped with a wire winding shaft and a film winding shaft 9 between a wire end fixing pipe 3 and a film end fixing pipe 5 so that both the winding shafts may be freely moved back and forth. A wire-film connecting shaft 11 is set between the wire winding shaft 7 and the film winding shaft 9 so that the connecting shaft 11 may be freely moved back and forth. Both the ends of plural wires fixed to the wire winding shaft respectively at the middle parts are fixed respectively to the wire end fixing pipe 3 and the wire-film connecting shaft 11. Both the ends of a film 21 fixed to the film winding shaft 9 at the middle part are fixed respectively to the film end fixing pipe and the wire-film connecting shaft 11. The wire winding shaft 7 is rotated by a drive motor 27 and the film winding shaft 9 is connected through a connector 31 equipped with a spring 29 to the wire winding shaft 7 or the drive motor 27. |
