In this embodiment, as shown in FIG. 7, a gap S1 for ventilation is secured between the heat insulating material 7 and the waterproof sheet 6 and the back surface 2B of each outer wall plate 2. The gap S1 for ventilation is appropriately set depending on the installation status of the structure 8 and the like. For example, the gap S1 for ventilation is preferably 7 mm or more from the viewpoint of ensuring ventilation. The gap for ventilation is not essential, and the gap S1 for ventilation in this embodiment can be omitted. In order to reduce the gap for ventilation in this way, the fixture 210 of Reference Example 1 described later, which does not have the support surfaces 13L and 13R, can be used.

As shown in FIGS. 11, 16 and 17, the support surfaces 13L and 13R of the fixture 10 abut on the back surfaces 2B of the first to fourth outer wall plates 2A1 to 2A4, and the first to fourth outer wall plates 2A1 to 2A4 are indoors. By restricting the position so as not to shift in the direction, the gap S1 for ventilation shown in FIG. 7 is surely secured. At this time, as shown in FIG. 10 and the like, since the substrate portion 16 extending substantially flat abuts on the vertical support member 50 over a wide area and is firmly fixed, the support surfaces 13L and 13R are also stable, and the first 1 to 4 outer wall plates 2A1 to 2A4 can be regulated.

<Effect>
In the fixture 10 of the first embodiment, as shown in FIGS. 9 and 11, the first locking portion 11 and the second locking portion 12 are separated from each other in the left-right direction by the separating portion 15. Therefore, in the first locking portion 11, the first locking piece 11A locks the upper end portion 2U of the first outer wall plate 2A1, and the second locking piece 11B engages the lower end portion 2D of the second outer wall plate 2A2. At the second locking portion 12, the third locking piece 12A locks the upper end portion 2U of the third outer wall plate 2A3, and the fourth locking piece 12B locks the lower end portion 2D of the fourth outer wall plate 2A4. In the state of locking, the first locking portion 11 and the second locking portion 12 have a gap between the second outer wall plate 2A2 and the fourth outer wall plate 2A4, and the first outer wall plate 2A1 and the third outer wall plate 2A3.

In addition, it is possible to prevent rainwater from entering the back surface 2B side of the outer wall plate 2.

Further, in this exterior structure, as shown in FIGS. 8, 11 and 17, etc., after the first to fourth outer wall plates 2A1 to 2A4 are attached to the structure 8 by the attachment 10, the lateral slip prevention portion of the attachment 10 According to 19, the lateral displacement of the first outer wall plate 2A1 and the third outer wall plate 2A3 can be prevented. Further, as shown in FIG. 11, the lateral slip prevention portion 19 is arranged between the back side left and right joint portions 22 of the first outer wall plate 2A1 and the front side left and right joint portions 21 of the third outer wall plate 2A3.
