先ず、ベース１３を、貫通穴３の開口９に通気切欠口１８を位置合わせし、ねじ挿通穴１９を挿通させたねじ４５により壁面４に固定する。次に配管類５を貫通穴３を通して屋内から屋外１２に配設し、開口９の近くで壁面４に沿わせて屈曲させる。このとき、配管類５をベース１３の一対の受部１７間に挿入して配設する。この状態からカバー部１５をベース１３に合わせて、ねじ止め固定する。このとき、給排気ダクト３２の先端部３２ａを突出部２９内に位置させる。次に、ウェザーカバー８を突出部２９を覆うようにカバー部１５に組み付ける。この場合、弾性フック３７を嵌合穴部３３に挿入し、鉤突部４０を嵌合穴部３３に係止する。この動作は、ウェザーカバー８をカバー部１５側へ押圧することでワンタッチで行うことができる。なお、ウェザーカバー８は、カバー部１５に予め取り付けておいても良い。 First, the base 13 is fixed to the wall surface 4 with the screw 45 inserted through the screw insertion hole 19 by aligning the ventilation notch 18 with the opening 9 of the through hole 3. Next, the piping 5 is disposed from the indoor to the outdoor 12 through the through-hole 3, and is bent along the wall surface 4 near the opening 9. At this time, the piping 5 is inserted and disposed between the pair of receiving portions 17 of the base 13. From this state, the cover portion 15 is aligned with the base 13 and fixed with screws. At this time, the tip end portion 32 a of the air supply / exhaust duct 32 is positioned in the protruding portion 29. Next, the weather cover 8 is assembled to the cover portion 15 so as to cover the protruding portion 29. In this case, the elastic hook 37 is inserted into the fitting hole 33, and the collar protrusion 40 is locked to the fitting hole 33. This operation can be performed with one touch by pressing the weather cover 8 toward the cover portion 15. The weather cover 8 may be attached to the cover portion 15 in advance.

ウェザーカバー８をカバー部１５に組み付けた後に、ウェザーカバー８を回動させて、開口部分３５を任意の位置に移動させる。通常は、図１に示すように、下方側へ開口部分３５が位置するように回動させる。この状態では、スリットに係合片部４４が係合することにより、位置決めされる。 After assembling the weather cover 8 to the cover portion 15, the weather cover 8 is rotated to move the opening portion 35 to an arbitrary position. Usually, as shown in FIG. 1, it rotates so that the opening part 35 may be located below. In this state, the engagement piece portion 44 is engaged with the slit for positioning.

そして、屋内側の空気は、給排気ダクト３２を通って、突出部２９内に排出され、突出部２９のスリット状の通気口１１から貫通穴３の開口９の外周縁部１０の面方向に沿って排出され、ウェザーカバー８の開口部分３５から屋外１２に排出される。 Then, the indoor air passes through the air supply / exhaust duct 32 and is discharged into the protruding portion 29, and from the slit-like vent 11 of the protruding portion 29 to the surface direction of the outer peripheral edge portion 10 of the opening 9 of the through hole 3. And is discharged from the opening portion 35 of the weather cover 8 to the outdoors 12.

However, in addition to the cylindrical shape, an arbitrary shape such as a rectangular column shape (rectangular tube shape) having a rectangular cross section may be employed as appropriate. good.

また、本実施形態において、係合突部４２自体は弾性を有しておらず、係合突部４２が設けられている側壁４１が弾性変形することによって、係合突部４２がスリットに弾性係合する例を示したが、係合突部４２自体が弾性変形することでスリット間を乗り越えるように、例えば、係合突部４２をウェザーカバー８の側壁４１に突設した係合片で形成しても良い。 In the present embodiment, the engagement protrusion 42 itself does not have elasticity, and the engagement protrusion 42 is elastically deformed by the slit by elastically deforming the side wall 41 on which the engagement protrusion 42 is provided. Although an example of engagement is shown, for example, the engagement protrusion 42 is an engagement piece that protrudes from the side wall 41 of the weather cover 8 so as to get over the slits by elastically deforming the engagement protrusion 42 itself. It may be formed.

また、本実施形態では、通気口として、突出部２９の周側壁３１の周方向全域にスリットを設けたが、周方向の全域に設けなくても良い。また、通気口としてはスリット以外に単なる開口でも良い。さらに、本実施形態では、通気口として複数のスリットを円筒状の突出部２９の軸方向に沿って設けた例を示したが、これに限らず、複数のスリットは突出部２９の軸方向に対して傾斜していても良く、周方向に沿って複数のスリットを形成しても良い。 Moreover, in this embodiment, although the slit was provided in the circumferential direction whole region of the peripheral side wall 31 of the protrusion part 29 as a vent hole, it does not need to provide it in the whole region of the circumferential direction. Further, the vent may be a simple opening other than the slit. Furthermore, in this embodiment, although the example which provided the some slit along the axial direction of the cylindrical protrusion part 29 as an air vent was shown, not only this but a some slit in the axial direction of the protrusion part 29 was shown. In contrast, it may be inclined, and a plurality of slits may be formed along the circumferential direction.

また、上記実施形態では、突出部２９の直径が、開口９の直径よりも大きい例について説明したが、開口９の直径よりも小径の突出部２９の場合もある。開口９の直径よりも小径の突出部２９の場合であっても、通気口１１は、開口９の外周縁部１０の面方向であって、開口９から放射状に向かう方向に向けて開口して設けられる。 In the above-described embodiment, the example in which the diameter of the protrusion 29 is larger than the diameter of the opening 9 has been described. However, the protrusion 29 may have a diameter smaller than the diameter of the opening 9.
