[Effect of device]

 As described above, according to the present invention, there is a double engagement between the slanted end surface of the decorative wall plate and the inclined portion of the connecting metal fitting and the engagement between the locking groove of the decorative wall plate and the inclined portion of the connecting metal fitting. Since the decorative wall plate is firmly attached to the mounting member 1 due to the mounting relationship, the decorative wall plate does not easily come off even when strong vibration is applied.

Further, in the case of a ceramic decorative wall plate, the end surface of each side of the decorative wall plate is formed such that the end surface is formed into an oblique shape, and then a locking groove is further formed on the same end surface. However, since both of these can be performed only by cutting with a diamond cutter, etc., even an unskilled operator can easily and quickly process the end surface.

Further, by forming the connecting metal fitting 4 with a spring member, the adhesion between the inclined portion on the metal fitting side and the slanted end surface on the decorative wall plate side, and further, the engaging portion on the metal fitting side and the cosmetic Adhesion with the locking groove formed on the end face on the wall plate side is improved, and it is difficult to loosen or come off even after installation due to vibration.

Further, in the case where the corner portion where the end face of the decorative wall plate intersects with the surface of the same wall plate is formed to be an obtuse angle, the front surface side of It is hard to lose the edge.

Further, by forming the connecting metal fitting into a rail-shaped connecting metal fitting having a length equal to or longer than one side of the decorative wall board, the decorative wall board can be formed over the entire circumference thereof. Since it is supported, it can be firmly attached, and at the same time, tilting is less likely to occur and workability is further improved.
