The one described in JP-A-105741 is known. This stopper is formed into a substantially inverted U-shape in cross section;
A fixing nail is inserted into the U-shaped recess to fix it to the wall while the upper end of the exterior plate installed below is fitted into the U-shaped recess. The problem to be solved by the present invention is that it can be constructed by engaging the lower ends of other exterior panels to be connected by joint pieces. Although it is possible to firmly fix it so as to press it against the surface, it is difficult to restrict sliding in the horizontal direction. In particular, when fitting the upper end male part of the exterior plate constructed below into the U-shaped recess, in order to secure a space for the fixing nail to be inserted,
It is not possible to stably position the stopper by pushing it in until the male end comes into contact with the inner end of this U-shaped recess.

Therefore, it is extremely difficult to hold and fix the fasteners horizontally to the exterior plate, and this requires skill and reduces workability. If the fastened fasteners are not in a strictly horizontal relationship with the exterior plate, not only will the finish and appearance of the exterior wall deteriorate, but if the exterior plate is placed on top of the slanted fasteners, the fasteners will be damaged. The load applied to the wall becomes uneven, reducing its supporting capacity, and the strength of the outer wall structure becomes insufficient.
