In particular, according to the structure of the present invention, the convex portion of the gasket has a lateral width corresponding to the joint width of the vertical joint, and the tip side of this convex portion is the end surface of the siding on both sides of the vertical joint. Since they are sandwiched, when the siding is attached to the outer wall base material, the joint width of the vertical joint becomes constant by abutting the end surface of the siding against the side surface of the ridge. That is, when the primary seal due to the irregular-shaped seal material is broken, the gasket for functioning as the secondary seal is also used as the ruler for defining the joint width of the vertical joint,
There is an advantage that the vertical joints of the siding can be installed accurately and uniformly without using a dedicated ruler.

Further, since the adhesion preventing layer of the irregular sealing material is formed on the tip end surface of the convex ridge portion of the gasket sandwiched between the end faces of the siding on both sides of the vertical joint, the convex ridge portion of the gasket is used as a backup material. Even though the irregular joint material is applied to the vertical joints, the irregular seal material does not adhere to the ridges of the gasket, resulting in a two-sided adhesive bond with only the siding end faces on both sides of the longitudinal joint. . Therefore, when the joint width increases due to contraction of the siding,
The entire irregular shaped sealing material is uniformly stretched, and it is possible to stop the irregular shaped sealing material within the range of the allowable elongation rate, and it is possible to prevent deterioration of the material of the irregular shaped sealing material due to repeated excessive elongation locally.
