The support 30 includes a vertical frame fixing part (31) fixed to a side part (11a) of the vertical frame (11) when seen from front, and a horizontal frame fixing part (32). The extension part (20) includes a first horizontal frame (21) formed by connecting a plurality of members. At a connection part of the first horizontal frame (21), one is connected to the horizontal frame fixing part (32) of the support (30) while the other is fixed to the vertical frame (11).SELECTED DRAWING: Figure 2 |
