For example, wallpaper may be attached to the outer surface 13 of the plate member 10, that is, the entire outer surface.

  The neutral 20 will be described with further reference to FIGS. 4 is a cross-sectional view showing a part of FIG. 2 in an enlarged manner, FIG. 5 is a schematic view showing a dimensional relationship among the plate material 10, the neutral 20 and the fixing member 30, and FIG. FIG. 7 is a perspective view of the neutral stand 20 taken out from the direction indicated by the arrow V. FIG. The pair of neutral stands 20 are provided so that their upper end portions are in contact with the upper member 2, their lower end portions are in contact with the lower member 3, extend in the vertical direction, and face each other via the storage portion 6. The neutral 20 is made of, for example, a metallic material, specifically made of steel. The thickness of the neutral 20 is, for example, 1 to 3 mm.

  The neutral stand 20 includes an inner wall 21 facing the storage portion 6, an outer wall 23 provided away from the storage portion 6 in the thickness direction of the plate member 10, and an end wall 22 connecting the inner wall 21 and the outer wall 23. Further, the outer wall 23 of the neutral stand 20 may include a bent wall 24 extending from the outer wall 23 toward the inner wall 21. Specifically, the inner wall 21 and the end wall 22 of the neutral stand 20 are connected vertically, the end wall 22 and the outer wall 23 are connected vertically, and the outer wall 23 and the bent wall 24 are connected vertically. Good. Further, the lateral width of the inner wall 21 is larger than the lateral width of the outer wall 23. The corners of the end wall 22 and the outer wall 23 and the corners of the outer wall 23 and the bent wall 24 may be chamfered, respectively. Further, the length of the end wall 22 may be determined by the thickness of the baseboard.

  With particular reference to FIGS. 4 and 5, the neutral 20 has an opening 25 between the inner wall 21 and the bent wall 24. The opening 25 receives the end portion on the front side of the plate member 10 when viewed in the pulling-out direction of the retracting door 9. In this case, the width W <b> 2 of the opening 25 of the neutral stand 20 is determined by the distance between the inner wall 21 and the bent wall 24. The thickness W1 of the plate 10 and the width W2 of the opening 25 are substantially the same. In addition, resin coating may be applied to the entire outer surface of the neutral 20, for example, a wood-tone seal may be attached.

  As described above, the end of the plate 10 is received in the opening 25 of the neutral 20. That is, in a state where the opening 25 of the neutral stand 20 receives the end of the plate member 10, the inner wall 21, the bent wall 24, and the end wall 22 of the neutral stand 20 are the inner surface 11, the outer surface 13, and the front end portion of the plate member 10.
