Next, a modification of the embodiment of the present invention will be described with reference to FIGS.
In this modification, the configuration of the spacer is changed. The other configurations except for the spacer are the same as those in the above embodiment, and the same parts are denoted by the same reference numerals and detailed description thereof is omitted.

  That is, as shown in FIG. 10, the spacers 77 are mounted at substantially equal intervals (for example, a pitch of 200 mm) in the circumferential direction with respect to the edge of the concave groove 31 on the anti-washing field 1 side. As shown in FIG. 11, the spacer 77 is mounted so as to wrap around the edge of the concave groove 31 on the side of the anti-washing field 1. Specifically, the spacer 77 is formed in a substantially L-shaped cross section that protrudes upward after the edge of the concave groove 31 on the side of the anti-washing field 1 protrudes outward (on the side of the anti-washing field 1). , An inner piece 771 in contact with the side of the edge of the washing area 1 from the inside (washing area 1 side), an upper piece 772 extending outward from the upper end of the inner piece 771 and in contact with the upper surface of the edge from above, and the upper side An outer piece 773 that extends downward from the outer end of the piece 772 and is in contact with the side surface of the anti-washing field 1 of the edge from the outside, and a lower piece 774 that extends inward from the lower end of the outer piece 773 are provided.

  As shown in FIGS. 12 and 13, the inner end of the upper piece 772 of the spacer 77 is located above the vicinity of the lower end edge of the wall panel 4 near the inner end (washing area 1 side end). An upright piece 775 is provided so as to protrude from the back surface of the backing material 42 of the wall panel 4 so that the inner surface is in contact therewith. The standing piece 775 includes a rib 775a that extends upward from a substantially central position in the width direction of the upper piece 772 (the frontward and rearward direction in FIG. 11), and the rib 775a reinforces the standing piece 775 that rises upward. Yes.

  Further, the inner piece 771 of the spacer 77 has a wall protruding inward so as to oppose the lower end edge of the resin decorative steel plate 41 of the wall panel 4 with a predetermined gap (for example, several millimeters) thereabove. A panel regulating piece 776 is provided. This wall panel restricting piece 776 restricts the upward movement of the resin decorative steel plate 41 over a gap between the wall panel 4 and the lower end edge of the resin decorative steel plate 41. Further, the lower piece 774 of the spacer 77 has an upper surface that opposes the lower surface of the edge of the concave groove 31 on the side of the anti-washing field 1 with a predetermined gap (for example, several millimeters) downward. . This lower piece 774 is the edge of the concave groove 31 on the side of the anti-washing field 1 even if the spacer 77 tries to move upward due to contact with the wall panel regulating piece 776 when the resin decorative steel plate 41 moves upward. It functions as a spacer regulating piece that regulates the upward movement of the spacer 77 beyond the gap with the lower surface of the spacer.

  In this case, since the inner side surface of the upright piece 775 standing upward from the vicinity of the lower end edge of the wall panel 4 near the inner end portion of the upper piece 772 of the spacer 77 is in contact with the back surface of the backing material 42 of the wall panel 4, The bathroom floor pan 3 is momentarily bent due to an unexpected impact when the user jumps or falls in the washing place 1 and the wall panel 4 placed on the placement portions 711 and 712 of the wall panel side joiner 71 It is reliably prevented that the lower end portion of the resin decorative steel plate 41 is lifted upward and separated from the outside (the back side of the wall panel 4). Thereby, the unexpected impact which arose in the washing place 1 is suppressed effectively, and the fixed state of the lower end part of the resin decorative steel plate 41 with respect to the edge of the bathroom floor pan 3 can be maintained firmly.

  Also, even if the bathroom floor pan 3 is momentarily bent due to an unexpected impact when the user jumps or falls in the washing place 1, the lower end portion of the resin decorative steel plate 41 of the wall panel 4 is lifted upward, The wall panel restricting piece 776 of the spacer 77 restricts the upward lifting of the resin decorative steel plate 41 beyond the gap between the lower end of the resin decorative steel plate 41. Further, when the resin decorative steel plate 41 moves upward, even if the spacer 77 tries to move upward due to contact with the wall panel regulating piece 776, it is between the lower surface of the edge of the concave groove 31 on the side of the anti-washing field 1. The upward movement of the spacer 77 beyond the gap is regulated by the lower piece 774 (spacer regulating piece). For this reason, an unexpected impact generated in the washing place 1 until the lower end of the resin decorative steel plate 41 collides with the wall panel regulating piece 776 of the spacer 77 and the upper surface of the lower piece 774 of the spacer 77 is concave. The groove 31 is smoothly absorbed until it comes into contact with the lower surface of the edge on the anti-washing field 1 side, and is sufficiently suppressed by the contact of the wall panel regulating piece 776 and the lower piece 774 of the spacer 77. Thereby, the unexpected impact which arose in the washing place 1 is suppressed more effectively, and the fixed state of the lower end part of the resin decorative steel plate 41 with respect to the edge of the bathroom floor pan 3 can be maintained still more firmly.

  Furthermore, since the spacers 77 are mounted at substantially equal intervals in the circumferential direction with respect to the edge of the concave groove 31 on the anti-washing field 1 side, unexpected shocks generated in the washing field 1 are spread over a wide circumferential range. It is suppressed and the fixed state of the lower end part of the resin decorative steel plate 41 with respect to the edge of the bathroom floor pan 3 can be firmly maintained over a wide range.

  In addition, this invention is not limited to the said embodiment, The other various modifications are included. For example, in the above-described embodiment, the wall panel side joiner 71 or the door frame side joiner 72 made of PP (polypropylene), and the sealing materials 714 to 716 or 726 made of an elastically deformable polymer gel (for example, PP gel), respectively. However, the material of the wall panel side joiner 71 and the door frame side joiner 72 and the material of the sealing materials 714 to 716 are not limited to this. For example, the wall panel side joiner and the door frame side joiner may be formed of ABS resin, and each sealing material may be formed of polymer gel (for example, olefin elastomer). In this case, each joiner and each sealing material cannot be molded at the same time, and cannot be joined with an adhesive. Therefore, in order to join the two, it is necessary to form a structure that can be mechanically fitted.

  Moreover, in the said embodiment, the 1st joint case 81 is interposed between the said wall panel 4 and the concave groove part 31 corresponding to the width direction edge part of the wall panel 4, and the mutually adjacent wall A second joint case 82 is interposed between the two wall panels 4 and 4 and the concave groove 31 corresponding to the joint between the ends of the panels 4 and 4, and at the corner of the bathroom floor pan 3.
