And, one end of the first flexible linear body 4 is stuck to the edge on one side in the lateral direction of the upper movable window plate 1a, and the other end to the edge on the other side in the lateral direction of the lower movable window plate 1b. One end of the second flexible linear body 6 is stuck to the edge on the other side in the lateral direction of the upper movable window plate 1a, and the other end to the edge on the other side of the lower movable window plate 1b, so that the first flexible linear body 4 and the second flexible linear body 6 become movable in the opposite directions each other.
