As shown in FIG. 4 (A), the seat portion 13 of the fixture 3 interposed between the floor surface 16 and the carpet 26 is formed as thin as possible, and the seat portion is Since the slanted surface 17 is formed at 13, the carpet 26 does not bulge upward around the Braille tack 1. The portion of the carpet 26 near the insertion hole 24 is gently upward along the inclined surface 17 of the seat portion 13, but is absorbed by causing the decorative layer 26b to enter the concave portion 9 of the Braille tack member main body 2 and thus the Braille tack member. The peripheral edge 8 of the main body 2 is cut into the decorative layer 26b. The radial rib 10 formed inside the recess 9 bites into the decorative layer 26b that has entered the recess 9. Therefore, even in the case of the warning tack 1b in which the disc-shaped Braille tack main body 2 rotatable about the tubular boss 5 with respect to the fixture 3, the rotation is prevented by the radial rib 10 biting into the decorative layer 26b. Therefore, there is no risk that the tubular boss 5 will be pulled out from the annular groove 18 due to wear or fatigue associated with rotation, and there is no risk that the Braille tack member main body 2 will fall off the carpet 26.

(Second Embodiment) In the floor structure to which the second embodiment shown in FIG. 5 is applied, the decorative sheet material 23 laid on the floor surface 16 is composed of floor tiles 27 made of vinyl chloride or the like. The thickness T3 is formed thinner than the wall thickness T1 of the carpet 26 described above.

The braille tack 1 has a diameter Dx of the seat portion 13 of the fixture 3 and a diameter or width Dy of the braille portion 4 of the braille tack main body 2, where Dy / Dx is 1.3 to 1.8 (in the example of the figure). In the case of 1.6), it is formed. The height Hx of the sleeve 15 protruding from the seat portion 13 of the fixture 3 is formed such that Hx = T3 or Hx≈T3 with respect to the thickness T3 of the floor tile 27. Further, the height Hy of the tubular boss 5 protruding from the recess 9 of the Braille tack member main body 2 is equal to that of the floor tile 27.
Is formed so that Hy = T3 or Hy≈T3 with respect to the thickness T3.

As described above, the sleeve 15 is inserted into the insertion hole 2

The first fixing means is constructed by fitting over 20. Further, the outer peripheral surface of the cylindrical boss 5 and the inner peripheral surface of the sleeve 15 are fitted to each other by the tapered surfaces 21 and 22, thereby constituting the second fixing means. Therefore, when the carpet 26 is laid on the floor surface 16, there is no risk that the tubular boss 5 will be pulled out from the annular groove 18 due to the influence of the external force, and the braille tack body 2 will be the carpet 26.
There is no danger of falling out of.

As shown in FIG. 5 (A), the seat portion 13 of the fixture 3 interposed between the floor surface 16 and the floor tile 27 is shown in FIG.
Since the diameter of the floor tile 27 is considerably smaller than that of the first embodiment shown in FIG. 1 and the inclined surface 17 is formed on the seat portion 13, the floor tile 27 does not bulge upward around the braille tack 1. Absent. A portion of the floor tile 27 near the insertion hole 24 is gently upward along the inclined surface 17 of the seat portion 13, but is located inside the peripheral edge 8 of the Braille tack member body 2 and is absorbed by the concave portion 9. The peripheral edge 8 of the braille tack body 2 is pressed against the surface of the floor tile 27. Therefore, from the outer peripheral area of the peripheral edge 8, the surface of the floor tile 27 is a flat surface. If the radial rib 10 formed inside the recess 9 is made to bite into the peripheral edge of the insertion hole 24 of the floor tile 27 that is inclined upward around the sleeve 15, the cylinder Even in the case of the warning tack 1b in which the disc-shaped braille tack main body 2 rotatable with respect to the fixture 3 around the shaped boss 5, the radial rib 10 biting into the insertion hole 24 can prevent the rotation. Since it is possible, the cylindrical boss 5 will be damaged due to wear and fatigue accompanying rotation.
There is no possibility that the braid will be pulled out of the annular groove 18, and the risk of the Braille tack member body 2 falling off the floor tile 27 can be prevented.
