PROBLEM TO BE SOLVED: To perform lighting control operation and lifting operation while linking with each other only by operating a first lifting cord.SOLUTION: One end of a first lifting cord 11 laid out in a head rail 13 through a lifting chang mechanism 17 is connected to the lower parts of a pair of shield materials 14 and 16, and the other end is suspended from the head rail for operation. A movable body 33 with a movable pulley 34 is provided movably only by a prescribed length between first and second fixation pulleys 31 and 32 in the head rail, one end of a second lifting cord 12 is connected to a shield material upper part, the other end is connected to the movable body through the first fixation pulley, and the first lifting cord is bridged over the second fixation pulley and the movable pulley. One shield material is lifted only by a prescribed length by operating the first lifting cord and moving the movable body with the movable pulley. In a state of stopping the movable body at a position of moving with the movable pulley only by a prescribed length, and stopping one shield material upper part, the first lifting cord is operated, and simultaneously the pair of shield material lower parts are lifted.SELECTED DRAWING: Figure 1 |
