Before With mounting portion 17 is formed with a flat surface, it is connected to the pillar portion 13, and characterized by having a wall portion 22 which is inclined towards the weather side.

  When hollow seal portions are provided on both sides of the column portion as in the invention according to claim 1, the fixed gasket is more easily compressed from the side than that provided on one side, and the outer wall panel is assembled. The reaction force is reduced and the workability of the outer wall panel assembly can be improved.

  According to the second aspect of the invention, the individual hollow portions formed by dividing the hollow seal portion into a plurality of partitions by the partition wall are deformed when one of the hollow portions is deformed. As a result, the hollow portions are more difficult to deform than those in which the hollow portions are individually independent. Accordingly, the hollow portion having the external appearance surface (most of which is a design surface) is not easily deformed, the appearance surface is not easily turned or deformed, and the flatness of the external appearance surface is easily maintained.

According to the invention of claim 3, the rigidity of the design layer provided at the outdoor side end of the column portion is increased by the inserted cored bar, thereby making the design layer difficult to deform and maintaining the flatness of the design surface. It becomes easy to do.
According to the invention of claim 4, among the hollow seal portions on both sides of the column portion , the mutually independent hollow seal portions are easily compressed, and the reaction force during assembly of the outer wall panel can be reduced. At the same time, the hollow seal portion provided with the external appearance surface is not affected by the deformation of the other hollow seal portions.
