The cushion material 50 is bonded to the container body 30 when the instrument container 10 is installed on the wall material W1, and the cushion material 50 and the container body 30 are separately transported to the construction site.

Next, the installation method of the instrument container 10 will be described together with the action.
First, as shown in FIG. 4, the wall hole Wb is formed in the wall material W1, and the cable wired on the back side of the wall material W1 with the instrument mounting frame 60 fixed to the back side of the wall material W1. K is pulled out from the wall hole Wb to the front side of the wall member W1, and on the front side of the wall member W1, the cable K is inserted into the bottom wall 13 of the cover body 11 and drawn inside the cover body 11.

  Next, the instrument container 10 is inserted into the wall hole Wb from the bottom wall 13 of the container body 30 from the front side of the wall material W1. And the cover body 11 of the instrument container 10 is inserted into the wall hole Wb until the front end side of the flange-side bulge part 38 is in pressure contact with the surface of the wall hole Wb peripheral edge of the wall material W1. . Then, the cushion material 50 is interposed between the inner surface extending in the longitudinal direction of the wall hole Wb and the outer surface of the first side wall 14 in the cover body 11. On the other hand, the inner surface extending in the short direction of the wall hole Wb and the outer surface of the second side wall 15 in the cover body 11 are in contact with each other, and a gap is hardly formed. Moreover, each 3rd side surface 50c of the cushion material 50 press-contacts the inner surface extended in the transversal direction of the wall hole Wb. In addition, one first side surface 50 a of the cushion material 50 contacts the back surface of the flange portion 21, and the other first side surface 50 a contacts the boss portion 61. Therefore, the entire wall hole Wb is closed by the cover body 11 and the cushion material 50 of the instrument housing 10.

  Next, the switch 63 is held in the holding hole 65 of the instrument holding frame 64, and the screw 19 is inserted into the screw insertion hole 64 a of the instrument holding frame 64. The screw 19 is inserted through the insertion portion 18 of the flange portion 21 to penetrate the insertion portion 18 in the thickness direction of the wall material W1, and the insertion space 51 of the cushion material 50 is penetrated in the thickness direction of the wall material W1. Then, the screw 19 is screwed into the female screw hole 61 a of the instrument mounting frame 60, and the instrument holding frame 64 is attached to the instrument mounting frame 60.

  As shown in FIGS. 5 and 6, when the instrument holding frame 64 is pressed against the wall material W <b> 1 in accordance with the screwing of the screw 19, the upper and lower parts of the instrument holding frame 64 and the instrument mounting frame 60 cause the flange portion 21. Both the upper and lower portions and the wall material W1 are sandwiched. Further, as the screw 19 is screwed, the distance between the instrument holding frame 64 and the instrument mounting frame 60 becomes narrower in the thickness direction of the wall material W1, and the cushion material 50 is shortened between the flange portion 21 and the boss portion 61. Compressed in the hand direction (thickness direction of the wall material W1). At this time, the third side surfaces 50c located at both ends in the longitudinal direction of the cushion material 50 are in pressure contact with the inner surface extending in the short direction of the wall hole Wb, and deformation in the longitudinal direction of the cushion material 50 is suppressed. Therefore, the cushion material 50 is deformed so as to swell in the thickness direction, and the other first side surface 50a of the cushion material 50 is in pressure contact with the inner surface extending in the longitudinal direction of the wall hole Wb, and the first side wall 14 (first The outer wall 34) is also pressed against the outer surface.

According to the above embodiment, the following effects can be obtained.
(1) The instrument container 10 includes a container body 30 and a cushion material 50. In the installed state of the instrument housing 10, a part of the wall hole Wb is closed by the cover body 11 and the other part is closed by the flange portion 21. At this time, in the wall hole Wb, a gap between the inner surface extending in the longitudinal direction of the wall hole Wb and the outer surface of the first side wall 14 of the cover body 11 is closed by the cushion material 50. For this reason, even if it is the instrument container 10 inserted in the wall hole Wb from the front side of the wall material W1 and installed in the wall material W1 by the screw 19 penetrating the flange portion 21, the entire wall of the instrument container 10 By closing Wb and closing the portion through which the screw 19 penetrates with the cushioning material 50, it is possible to improve sound insulation and airtightness at the place where the instrument housing 10 is installed.

  (2) The flange portion 21 of the appliance container 10 is disposed on the surface of the wall material W1, and the flange portion 21 is covered with a decorative cover after the appliance container 10 is installed. For this reason, in order to prevent the decorative cover from significantly rising from the surface of the wall material W1, the flange portion 21 cannot be thickened. In the present embodiment, since the cushion material 50 is disposed in the wall hole Wb on the back side of the flange portion 21, even if the flange portion 21 is thin, sound insulation and airtightness can be improved. Therefore, it is not necessary to increase the thickness of the flange portion 21, and the decorative cover does not float up.

  (3) In the installed state of the instrument housing 10, the cushion material 50 can close the gap between the inner surface extending in the longitudinal direction of the wall hole Wb and the outer surface of the first side wall 14 of the cover body 11. For this reason, even if it encounters an emergency fire, it suppresses the leakage of the air from between the inner surface extended in the longitudinal direction of the wall hole Wb and the 1st side wall 14 outer surface of the cover body 11 to the back side of wall material W1. Also, fire resistance can be improved.

  (4) When the instrument holding frame 64 is attached to the instrument mounting frame 60 using the screws 19, the cushion material 50 comes into contact with the back surface of the flange portion 21 and the boss portion 61 of the instrument mounting frame 60, and the cushion material 50 is moved in the short direction. Can be compressed. For this reason, the cushion material 50 is inflated in the thickness direction by the compression of the cushion material 50, one first side surface 50a of the cushion material 50 is pressed against the first side wall 14 of the cover body 11, and the other first side surface 50a is The inner surface of the hole Wb extending in the longitudinal direction can be pressed. Therefore, the gap between the inner surface extending in the longitudinal direction of the wall hole Wb and the outer surface of the first side wall 14 of the cover body 11 can be reliably closed by the cushion material 50.

  (5) The length S of the cushion material 50 in the short direction is longer than the length M of the wall material W1 in the thickness direction. For this reason, if the wall material W <b> 1 is sandwiched between the flange portion 21 and the instrument mounting frame 60, the cushion material 50 can be compressed by the flange portion 21 and the instrument mounting frame 60.

  (6) A part of the cushion material 50 in the short side direction is bonded to the flange portion 21 and the first side wall 14, and the other part is not bonded and is in an unrestrained state. For this reason, the cushion material 50 can be compressed by the flange portion 21 and the instrument mounting frame 60.

  (7) The container body 30 of the instrument container 10 has a double wall structure, and a filler J is filled between the double walls. The filler J has a sound insulation performance and covers the peripheral wall. For this reason, the sound insulation performance of the cover body 11 can be enhanced by the filler J.

  (8) The flange portion 21 is also filled with the filler J, and the insertion portion 18 is formed through the filler J. For this reason, also in the flange part 21, the sound insulation can be improved by the filler J.

  (9) The cushion material 50 includes an insertion space 51, and the insertion space 51 is disposed at a position facing the insertion portion 18 of the flange portion 21. For this reason, when the screw 19 penetrating the insertion portion 18 of the flange portion 21 is inserted into the cushion material 50, the screw 19 can be easily passed through the cushion material 50 by the insertion space 51.
