It is formed in a rectangular shape when viewed from the front. In other words, the left and right edges and the upper and lower edges of the base body 4 </ b> A serve as flanges for the opening 5 of the door 1.

  Next, as shown in FIG. 2, the vertical portion of one end portion (end portion on the door bottom side) 16 is the same vertical plane as the vertical portion of the other end portion (end portion on the door end side in the embodiment) 17. It is not located on the upper side, and the one end portion 16 falls to the back surface (bottom wall portion) side.

  In other words, the vertical portion of the other end portion 17 is thicker than the vertical portion of the one end portion 16. The detailed description of the pedestal main body 4A is omitted, but in the front side portion, one or a plurality of step portions from the vertical portion of the other end portion 17 to one end portion (door bottom side) 16 Is repeated to form a “large cut-out portion 18” having a concave shape facing the front. Further, in the large cut-out portion 18, a recessed portion 19 for the engagement plate 25 is formed vertically long at a portion near the one end portion (door bottom side) 16.

  As shown in FIGS. 3 and 4, the recessed portion 19 is formed with one positioning guide hole 7 at the center (center portion), and the positioning guide hole 7 is used as a reference. The small through holes 21 for the fixing tool 6 are formed in the upper part and two in the lower part with a predetermined interval. Therefore, the fixing tool 6 is positioned in these through small holes 21. In this embodiment, a set of engagement holes 22 are formed in a part of the bottom plate portion of the pedestal main body 4A (for example, the recessed portion 19) at a predetermined interval.

  Next, FIG. 5 shows a configuration related to the engagement hole 22. The engagement hole 22 is a guide long hole formed in the lateral direction in the thick part of the bottom plate portion of the pedestal main body 4A. The engagement hole 22 is naturally an elastic engagement claw provided in the engagement plate 25. It is formed in a shape that allows insertion of the piece 26.

  Thus, in this embodiment, at least one inner end surface (both inner end surfaces in the embodiment) 19a of the recessed portion 19 described above is an inclined surface that gently follows the inclined edge 22a of the engagement opening of the engagement hole 22. When the engaging claw piece 26 of the engaging plate 25 is completely snap-fit engaged with the engaging hole 22 via the recessed portion 19, the inner end surface 19a of the recessed portion 19 and the engaging plate 25 are A gap 23 is formed between the end edge and the tip of the engaging plate separating tool can enter. Although detailed description is omitted, as shown in FIG. 7, lattice-shaped reinforcing ribs 20 are formed on the inner surface of the engagement plate 25.
