As a result, the surplus band member 4 is arranged in the wall hole B, and the lid member 3 can be prevented from protruding outward.

Finally, as shown in FIG. 10, the cap member 5 is mounted in the cap mounting recess 23 of the lid member 3 to make the band insertion hole 27 and the surplus band member 4 invisible from the outside. Thereby, the aesthetic appearance of the wall hole closing tool 1 can be enhanced.

In the above embodiment, the elastic blade 5 is horizontally formed by a vertical portion 34 which is erected from the connecting plate 31 in parallel with the band member 4 and a horizontal portion 35 which is folded outward from the upper end of the vertical portion 34. Although it is composed of an inclined portion 36 that is folded downward from the outer end of the portion 35, the gist of the present invention is not limited to this, and other configurations may be used.

In the elastic wing piece 60 shown in FIGS. 11 and 12, one of the two band members formed on the left and right sides of the band member 4 has one elastic wing piece 60 perpendicular to the connecting plate 31 and the band member 4. It is composed of a base portion 61 that is erected upward and an elastic portion 62 that projects outward from the tip portion of the base portion 61. Further, the other elastic wing piece 60 has a base portion 63 perpendicular to the connecting plate 31 and the band member 4 and vertically hung downward, and an elastic portion 64 projecting outward from the tip end portion of the base portion 63. It is composed of and. The front side 62a of the elastic portion 62 and the front side 64a of the elastic portion 64 are inclined in a direction approaching the connecting plate 31 from the inner end portion to the outer end portion thereof.

Since the elastic wing piece 60 of this example is configured in this way, when the elastic wing piece 60 is inserted into the wall hole B, the front side 62a of the elastic portion 62 and the front side 64a of the elastic portion 64 are first placed at the end of the wall hole B. Be abutted. When the elastic blade piece 60 is further pushed in from this state, since the front sides 62a and 64a are inclined, a moment for elastically deforming the elastic portions 62 and 64 is generated, and the elastic portions 62 and 64 are automatically deformed. The diameter is reduced. Therefore, even when the elastic wing piece 60 of this example is used, the temporary fixing work of the lid member 2 can be facilitated as in the case of using the elastic wing piece 5 according to the embodiment.
