In addition, although the metal material, such as iron, may be used for the extrusion process material for manufacturing the side plate 120, in this embodiment, the aluminum alloy which is excellent in extrusion processability, a neat appearance, and is beautiful is used.

2 and 4, three reinforcing flanges 121 to 123 extending along the longitudinal direction of the side plate 120 are integrally formed on the inner side surface of the side plate 120. That is, the reinforcing flanges 121 to 123 are manufactured separately, and are not coupled to the inner side of the side plate 120, but are integrally manufactured together with the side plate 120 by extrusion. Accordingly, the extrusion die is designed to correspond to the cross section of the side plate 120 including the cross sections of the reinforcing flanges 121 to 123. Meanwhile, as shown in FIGS. 2 and 4, the reinforcing flanges 121 to 123 have a bent cross-sectional shape, which is easily fastened with the edge coupling member 130 at the ends of the reinforcing flanges 121 to 123.
