Moreover, although the fittings 1 of this embodiment are provided with two windows 1a and 1b, they may be provided with three or more windows.

[Window unit]
As shown in FIG. 2, the fitting 1 includes a first window unit 2A forming the window 1a and a second window unit 2B forming the window 1b, and includes a plurality of window units 2A and 2B (for example, three The fittings 1 including two windows 1a and 1b are constructed by connecting the windows 1a and 1b through the connecting screws 31 (see FIGS. 3 to 6). In other words, each window unit 2A, 2B is provided with divided mullions 44A, 44B (shaped by dividing mullion 1c in the horizontal direction), and the divided mullions 44A, 44B are butted against each other during construction. By connecting them, a mullion 1c is constructed.

Next, the configurations of the first window unit 2A and the second window unit 2B will be explained with reference to FIGS. 2 to 4. Although the configurations of the first window unit 2A and the second window unit 2B are different in the left and right positions of the divided mullions 44A and 44B and the left and right widths of the windows 1a and 1b, other parts are substantially the same. , the common parts of both window units 2A, 2B may be given the same reference numerals and the explanations may be used.
