Further, sealing materials 61d and 62d are applied to the inside of the L-shaped backup material 61a in the left-right direction of the smoke exhaust glass 51a.

Here, in the smoke exhaust vertical frame 530 in which the left and right ends of the smoke exhaust glass 51a are arranged, the left vertical frame main body 612 and the right vertical frame main body 622 are L-shaped in cross section as shown in FIG. It is formed. The left vertical frame main body 612 and the right vertical frame main body 622 are formed in an L-shape that is open to the side opposite to the upright 23 (inside the upright 23) and the outdoor side. Since the opposite side of the left vertical frame body 612 and the right vertical frame body 622 (the inside of the vertical side 23) and the outdoor side of the vertical frame body 622 are open, the smoke exhaust glass 51a is not moved in the left-right direction. The smoke exhaust glass 51a can be easily attached to the inside of the smoke exhaust frame 500 only by moving in the expected direction as well as moving in the direction (so-called Kendon type).

Further, when the smoke exhaust glass 51a is replaced due to damage or the like, the smoke exhaust glass 51a can be removed from the left vertical frame 611 by removing the covering member 61e and moving the smoke exhaust glass 51a to the outdoor side in the expected direction. You can Therefore, for example, maintenance can be performed more easily than using a vertical frame having a substantially U-shaped glass groove.

Further, since the left vertical frame main body 612 is formed in an L-shape in cross-section, a mounting margin for mounting glass, which is required when the glass groove having a substantially U-shape is formed, is provided in the finding direction. Since it does not need to be provided, the width in the finding direction can be made smaller than in the case of using a vertical frame having a substantially U-shaped glass groove. As a result, the appearance can be improved.

As described above, according to this embodiment, the following effects are achieved.
In the smoke evacuation window 51 of the present embodiment, the smoke evacuation lower frame 520 has at least the outdoor side portion 523 arranged on the outdoor side with respect to the finding surface 24b on which the bearing arcuate portion 243d of the blind 24 is arranged. Have. Since the outdoor side portion 523 is arranged on the outdoor side with respect to the found surface 24b on which the bearing arcuate portion 243d is arranged, the outdoor side portion 523 and the bearing arcuate portion 243d are arranged side by side in the expected direction. The vertical size of the smoke exhaust window 51 can be reduced. This can improve the appearance of the smoke exhaust window 51. Further, it becomes difficult to visually recognize the gap between the smoke lowering frame 520 and the blind 24 from the outside, so that the appearance of the smoke exhausting window 51 can be improved in design.
