The boundary part has a first stacked part formed by stacking three plate materials so as to pinch one end of the plate material. The second closed section has a second stacked part including a U-shaped part provided to the side wall and formed to inscribe the other end of the plate material. The holding part has a third stacked part formed by stacking two plate materials.SELECTED DRAWING: Figure 2
