[Effect of idea]

As mentioned above, the locking edge according to the present invention is composed of two members: the locking body that is fixed to the wall base, and the decorative cap that covers the end of the wall material, making it easy to drive nails. Therefore, the driving position of a fixing tool such as a nail can be determined regardless of the width of the decorative surface portion of the decorative cap, so there is no need to particularly widen the width of the rim or the like. Furthermore, since the decorative cap is attached after the locking body and the wall material are fixed, the wall material and the decorative cap do not rub against each other, and the surface of the wall material is not damaged. Furthermore, since the engaging protrusions formed on the decorative cap are spaced apart, the insertion portion can be easily fitted into the locking groove and difficult to separate. Moreover, since the cosmetic cap can be attached by simply inserting it into the locking body, it has the characteristic that it does not cause dents or deformation. moreover,
Since there is no need to insert wall materials, it is easy to measure the dimensions of the wall materials, making construction easier. It has the following effects and characteristics.
