Therefore, the cord assembly 50 has excellent strength because it is integrally woven. In addition, since a connecting member is not provided between the control cord 52 and the blade penetration cord 54, when the control cord 52 controls the lower beam portion 20 to get on and off, the cord assembly 50 on the rotating wheel 44 slides. Smoothness can be achieved, and interference with the adjacent control cord 52 or blade penetration cord 54 can be prevented. Furthermore, the user can get on and off while keeping the horizontal state of the lower beam portion 20 only by pulling the control code 52. Therefore, it is possible to prevent the lower beam portion 20 from being inclined due to the imbalance of the acting force.

  By installing the convex edge portion 44b of the rotating wheel 44, it is possible to prevent the adjacent cord assemblies 50 from being entangled with each other. Further, since the semi-rotation surfaces 44c on both sides of the convex edge portion 44b are inclined, the cord assembly 50 wound around the rotating wheel 44 is prevented from entering the gap between the rotating wheel 44 and the frame 42. can do. Therefore, the smooth opening / closing of the window shielding apparatus 100 can be ensured, and the failure rate can be reduced. In the present embodiment, the control cord 52 and the blade penetration cord 54 are flat and have a relatively large contact area with the rotating surface of the rotating wheel 44. Therefore, the stability of the cord assembly 50 can be improved during operation. Furthermore, in this embodiment, the rotating wheel 44 is made by a modularization method, and the convenience of recombination can be enhanced.

  As shown in FIG. 14, a partition member 48 is provided on the frame 42. The two blade penetration cords 54 pass through both sides of the partition member 48, respectively. Thereby, it can prevent that the two blade | wing penetration cords 54 are mutually entangled.
