外観品質を向上させることができる。In this embodiment, since the lip portion 26 is provided on the outdoor side of the primary gasket portion 22, the pressure contact portions 22A of the primary gasket portion 22 and the pressure contact portions 24A of the secondary gasket portion 24 are connected to each other as described above. When is pressed, the lip portions 26 facing each other are pressed at the same time. Therefore, when viewed from the joint side, only the lip portions 26 that are in pressure contact with each other are exposed, and the primary gasket portion 22 and the like of the fixed gasket 18 are not exposed to the joint side. Further, in the case of the conventional structure, as a result of retracting the fixed gasket to the indoor side in order to prevent deterioration due to direct sunlight, which will be described later, a deep groove is formed in the joint between the outer wall panels 10 and the appearance quality is deteriorated. However, according to this embodiment, since the lip portion 26 is arranged in pressure contact with the joint, the deep groove as described above does not occur. Therefore, according to this embodiment, the appearance quality of the joint between the outer wall panels 10 can be improved.

ができる。In addition, in this embodiment, since the protrusion 28 is provided on the extending portion 20D of the base portion 20, as the amount of elastic deformation of the lip portion 26 increases, the lip portion 2 starts from a certain point.
The tip portion of 6 contacts the inclined surface 28A of the protrusion 28. For this reason, the amount of elastic deformation of the lip portion 26 depends on the inclined surface 2 of the protrusion 28.
It is regulated by 8A. Therefore, in general, the lip portion 26
The distal end of the lip is pushed toward the indoor side by pressure contact, and as the joint width becomes narrower, a deep recess is formed on the surface of the lip portion 26 on the outdoor side, which becomes a shadow, but according to the present embodiment, as described above, The amount of elastic deformation of the portion 26 depends on the inclined surface 28 of the protrusion 28.
Since it is regulated by A, the amount of depression of the surface portion can be regulated. Therefore, the appearance quality of the joint between the outer wall panels 10 can be improved in the sense that no deep recess is formed on the surface of the lip portion 26 and no shadow is formed.

を向上させることができるという優れた効果を有する。As explained above, the outer wall joint structure according to the present invention is provided on the outdoor side of the fixed gasket so as to be elastically deformable, and has an arc-shaped protective portion that conceals the fixed gasket when viewed from the joint side. Since it has a regulating means for regulating the elastic deformation amount of the protective portion when the protective portion is pressed, it has an excellent effect that the appearance quality of the outer wall joint can be improved when the fixed gasket is used.
