Claims

[Claims for Utility Model Registration] A hollow portion is formed inside, a thin metal plate for preventing shrinkage is integrally formed along the lower surface in the longitudinal direction, and a thick covering is provided on the front wall of the upper half of the hollow portion. Forming a crown bulge, forming a horizontal covering edge extending toward the tread side on the rear wall of the upper half, and a flexible filling material with the lower half serving as an insertion part, and a stair nosing. At the tip of the flat plate part to be fixed to, there is a front end locking ridge with a smooth upper surface connected to the locking front edge provided vertically downward, and at the rear end, there is a front end locking ridge with a smooth surface on the upper surface. A rear end locking ridge having a hook part whose upper end edge is bent slightly inward while leaving an extending mounting portion is provided respectively, and the above-mentioned front and rear end locking ridges and the flat plate part form an upwardly directed concave groove. The insertion part formed on the lower half of the filler is inserted into the upward groove of the metal base, and the thin metal plate formed on the lower surface is fixed by adhesive. In this state, the lower surface of the crowned bulge formed on the distal side is crowned so as to contact the smooth surface formed on the upper surface of the front end locking ridge, and the hook of the rear end locking ridge is A non-slip material for stairs with a double-sided flooring, characterized in that a void is formed between the filler and the covering edge formed on the rear wall of the filling material.
