という問題もあった。By the way, the floor panel 1 is often constituted by filling a hollow portion between the upper panel and the lower panel with, for example, an inorganic filler. When the positioning hole 30 is formed in the flange portion 3 of the panel opening 2 as in the related art,
A step of forming the positioning holes 30 is separately required, which not only increases the cost of the floor panel 1 but also causes the filler filled in the floor panel 1 to leak out of the positioning holes 30 to the outside, and the appearance of the floor panel 1 However, there has been a problem that the quality is reduced or rust or the like is generated to cause quality trouble. In addition, the flange portion 3 supporting the wire cover plate 5 'cannot be formed so wide from the viewpoint of securing the strength. Therefore, the hole diameter of the positioning hole 30 of the flange portion 3 and the diameter of the wire cover plate 5'. Each of the fitting projections 62 has a small diameter, which makes it difficult to align the wiring cover plate 5 'with the panel opening 2 at the time of mounting the wiring cover plate 5'. In addition to the difficulty in attaching and detaching the plate 5 ′, the plate 5 ′ is likely to be displaced in the horizontal direction, and the wiring is not carried out at the proper position shown in FIG. Cover plate 5 'is easily attached. In this case,
If a load, impact, or the like caused by stepping on a person acts thereon from above, there is also a problem that the fitting convex portion 62 of the wire cover plate 5 'is deformed or broken, and the positioning function is reduced. .

うになる。Next, the operation will be described. First, when the underfloor wiring 18 is pulled out onto the floor panel 1, as shown in FIG. 4, the underfloor wiring 18 is first pulled up from the panel opening 2 to the surface 1a side of the floor panel 1, and then the chip portion 7 is peeled off. The plate portion 6 having the through hole 13 formed therein is placed in the panel opening portion 2, and the plate portion 6 is pressed down toward the panel opening portion 2 while the underfloor wiring 18 passes through the through hole 13. As a result, the fitting projection 8 on the back surface 6b of the plate 6 shown in FIG. 1 is fitted from above along the recess 4 formed at the corner of the flange 3 of the panel opening 2, and the panel opening 2 and the plate portion 6 are positioned in the horizontal direction to prevent the plate portion 6 from coming off in the horizontal direction, and the spherical locking projection 9 is locked on the lower surface side of the flange portion 3 from the lateral direction C. As a result, the plate portion 6 is prevented from falling in the vertical direction B, and the plate portion 6 can be attached to the panel opening 2 in a state where abnormal noise and rattling do not occur. Then, FIG.
In the state where the top plate 7a of the chip portion 7 is inclined upward and forward as shown by the imaginary line, the convex portion 12 having the acute angle of the top plate 7a is formed.
On the first receiving portion 14 on the plate portion 6 side (FIG. 2).
(FIG. 2 (c)) and the recess 16 of the side plate 7b is placed on the second receiving portion 15 on the side of the flange 3 (state of FIG. 2 (b)), whereby the underfloor wiring 18 at the panel opening 2 is formed. The bent portion 18a (FIG. 4) can be protected by the tip portion 7.

きる。According to the above configuration, the recess 4 is formed at the corner of the flange 3 in the direction A away from the panel opening 2, and the back 4 b of the plate 6 is formed in the recess 4.
By fitting the fitting projection 8 provided on the side in the vertical direction B, the positioning hole 30 is formed in the flange 3 as in the conventional case.
The step of penetrating (FIG. 9) is not required, so that the cost of the floor panel 1 can be reduced, rust and poor appearance due to leakage of the filler in the floor panel 1 can be prevented, and quality problems due to the generation of rust can be prevented. Can be avoided. Moreover, since the recess 4 is formed so as to be recessed in the direction A away from the panel opening 2, even when the flange 3 is narrow, the inner diameter of the recess 4 can be set to be large. Can be configured with a large outer diameter, so that it is easy to attach the cover plate 5 for a wire to a regular position, and a load acting from above when a person steps on or the like. Deformation or destruction of the fitting projection 8 of the wire cover plate 5 due to shock or impact, etc. can be prevented.
This facilitates attachment and detachment and improves the positioning function.

In the case where a load or impact caused by stepping on a person or the like acts on the wire from above, since there is no protection for the wire in the past, the wire coating was damaged, torn, and the wire was broken. Since the chip portion 7 peeled off from the plate portion 6 as described above can be reused to protect the electric wire of the underfloor wiring 18, such a problem does not occur, and the chip portion 7 can be reused without being discarded. Because it is possible, there is no need to generate waste.

And the shape is formed to be substantially spherical, so that the locking projection 9 has a structure having a certain degree of freedom of attachment and detachment, and the attaching and detaching directions and the attaching and detaching angles of the line cover plate 5 are limited. As a result, it becomes easier to attach and detach the cover plate 5 for wiring. In addition, since the locking claws 61 (FIG. 9) project from the back surface 6b of the plate portion 6 in the related art, there is a problem that the mold becomes complicated. However, in the present invention, the locking projection 9 is formed into a spherical shape. Since it is formed, a complicated mold is not required, and the formation of the locking projection 9 is facilitated, so that there is an advantage that the cost can be further reduced.
