The guide bar 22 surrounds the opening 911' with the side wall 90' and defines the air chamber 200, and the window 51 closes the outlet 202 of the air chamber 200. This configuration also retains the characteristics of two different ventilation paths.

According to the above description, the advantages of the present invention can be summarized as follows.
1. Since the ratio of the area of the opening of the outlet 202 to the total area of the openings of the ventilation grooves 311 is 3 or more, the air flow rate of the second ventilation path (F2) is the air flow rate of the first ventilation path (F1). Much larger. The straighter second ventilation path (F2) is better for removing smoke from the building 9.
2. The glazing 512 provides natural light into the building and reduces the use of mechanical lighting and the heat generated thereby.
3. As shown in FIGS. 2 to 7 and 9, since the connecting sheet 4 is covered with the window 51, rain leakage from the gap between the connecting sheet 4 and the window 51 is prevented.
4. In the event of a fire, the window 51 is changed from the closed position to the open position by using the drive member 52 and the control unit 53, and the second ventilation path (F2) can be quickly opened to remove smoke.
