A vertical supporting plate (15) is hanged from the end of the horizontal supporting plate (12) on the side opposite to the front side plate (6) without being fixed to the inner surface of the box barrel part (2). The lower end of the vertical supporting plate (15) is separated upwardly from the box bottom part (3). A middle bottom plate (16) is fixed to the front side plate (6) in a cantilever manner between the box bottom part (3) and the horizontal supporting plate (12). The end of the middle bottom plate (16) on the side opposite to the front side plate (6) is connected to the lower end of the vertical supporting plate (15).
