     본 발명은 하나의 금속패널을 이용하여 좌우 양쪽을 절곡 성형하여 기둥프레임(100)을 일체로 성형한 내함(300)과, 하나의 금속패널을 이용하여 절곡 성형하여 선단에 수평프레임(200)을 일체로 성형한 다수의 칸막이패널(400)으로 구성되며, 상기 칸막이패널(400)들의 양측단에는 다수의 끼움돌기(400a)를 일체로 형성하고, 상기 칸막이패널(400)들이 위치되는 내함(300)의 양쪽 벽면에는 상기 끼움돌기(400a)를 끼울 수 있도록 끼움공(300a)을 형성하여, 상기 칸막이패널(400)을 상기 내함(300)에 끼워맞춤식으로 결합시킬 수 있도록 한 것이다.
