　図３は、本発明の実施の形態１の換気用スリーブの形状を説明する図である。第１円筒部６ａの外周面６ｅには第１ねじ部６ｃが、また第２円筒部７ａの内周面７ｄには第２ねじ部７ｃが形成されている。第１ねじ部６ｃと第２ねじ部７ｃとは螺合し、第１スリーブ６が内側、第２スリーブ７が外側となる。第１ねじ部６ｃは、第１円筒部６ａの外周面６ｅに長さＬ１に渡って形成される。第２ねじ部７ｃは、第２円筒部７ａの内周面７ｄの一端部に１～５ねじ山ピッチ程度のねじ部長さＬ２に形成される。 FIG. 3 is a diagram illustrating the shape of the ventilation sleeve according to the first embodiment of the present invention. A first screw portion 6c is formed on the outer peripheral surface 6e of the first cylindrical portion 6a, and a second screw portion 7c is formed on the inner peripheral surface 7d of the second cylindrical portion 7a. The first screw portion 6c and the second screw portion 7c are screwed together so that the first sleeve 6 is on the inside and the second sleeve 7 is on the outside. The first screw portion 6c is formed over the length L1 on the outer peripheral surface 6e of the first cylindrical portion 6a. The second screw portion 7c is formed at one end portion of the inner peripheral surface 7d of the second cylindrical portion 7a with a screw portion length L2 of about 1 to 5 thread pitch.

　図４は、本発明の実施の形態１の換気用スリーブの第２スリーブの円筒部を示す斜視図である。第２ねじ部７ｃを形成するねじ山１０は、第２円筒部７ａの軸１１方向から見た場合、ねじ山１０同士が重ならないように欠けていて、ねじ山１０ａ、１０ｂ・・と不連続となっている。 FIG. 4 is a perspective view showing a cylindrical portion of the second sleeve of the ventilation sleeve according to the first embodiment of the present invention. When viewed from the direction of the axis 11 of the second cylindrical portion 7a, the screw thread 10 forming the second screw portion 7c is lacking such that the screw threads 10 do not overlap with each other, and is discontinuous with the screw threads 10a, 10b,. It has become.

　図２に示すように第１円筒部６ａのねじ山開始位置と、第２円筒部７ａのねじ山１０開始位置とが一致する位置には、第１マーク１２と第２マーク１３とが一致されて設けられている。すなわち第１スリーブ６、および第２スリーブ７のそれぞれの円筒部である第１円筒部６ａ、第２円筒部７ａにおいて、第１フランジ６ｂ、第２フランジ７ｂと反対の端部６ｇ、７ｇに第１ねじ部６ｃ、第２ねじ部７ｃそれぞれのねじ山の開始位置が一致するマークが設けられている。また第１フランジ６ｂには、壁１にねじ止めするためのねじ孔１６が設けられている。 As shown in FIG. 2, the first mark 12 and the second mark 13 are coincident with each other at the position where the thread start position of the first cylindrical portion 6a coincides with the thread 10 start position of the second cylindrical portion 7a. Is provided. That is, in the first cylindrical portion 6a and the second cylindrical portion 7a which are the cylindrical portions of the first sleeve 6 and the second sleeve 7, the first flange 6b and the second flange 7b are opposite to the end portions 6g and 7g opposite to the first flange 6b. A mark in which the screw thread start positions of the first screw portion 6c and the second screw portion 7c coincide is provided. The first flange 6b is provided with a screw hole 16 for screwing to the wall 1.

　図３に示すように第１円筒部６ａの内周面６ｄは、なだらかな円錐形状であり、第１円筒部６ａの下部１４ａは屋外４側に向かい下り勾配θの傾斜となっている。同様に第２円筒部７ａの内周面７ｄもなだらかな円錐形状であり、第２円筒部７ａの下部１４ｂは屋外４側に向かい下り勾配θの傾斜となっている。 As shown in FIG. 3, the inner peripheral surface 6d of the first cylindrical portion 6a has a gentle conical shape, and the lower portion 14a of the first cylindrical portion 6a is inclined toward the outdoor 4 side with a downward gradient θ. Similarly, the inner peripheral surface 7d of the second cylindrical portion 7a has a gentle conical shape, and the lower portion 14b of the second cylindrical portion 7a is inclined toward the outdoor 4 side with a downward gradient θ.

　第１フランジ６ｂ側の外周には、第１スリーブ６の位置決めを行う孔用リブ１５が設けられている。孔用リブ１５は、第１円筒部６ａの外周面６ｅにほぼ均等に数箇所形成されている。孔用リブ１５の外周寸法Ｄ１は、第２円筒部７ａの外周寸法Ｄ２よりも大きい。 A hole rib 15 for positioning the first sleeve 6 is provided on the outer periphery on the first flange 6b side. Several hole ribs 15 are formed on the outer peripheral surface 6e of the first cylindrical portion 6a substantially equally. The outer peripheral dimension D1 of the hole rib 15 is larger than the outer peripheral dimension D2 of the second cylindrical portion 7a.

　このような構成の換気用スリーブ５の施工について説明する。図２に示すようにまず、第１スリーブ６が屋内３側から挿入され、第２スリーブ７は屋外４側から挿入される。このとき、第２スリーブ７の第２マーク１３が第１スリーブ６の第１マーク１２と一致するように挿入され、取っ手９を使って第２スリーブ７が回転される。このように第１スリーブ６と第２スリーブ７とが螺合される際、取っ手９を保持して第２スリーブ７が回転されるため、換気用スリーブ５の換気口への施工が簡単になる。 The construction of the ventilation sleeve 5 having such a configuration will be described. As shown in FIG. 2, first, the first sleeve 6 is inserted from the indoor 3 side, and the second sleeve 7 is inserted from the outdoor 4 side. At this time, the second mark 13 of the second sleeve 7 is inserted so as to coincide with the first mark 12 of the first sleeve 6, and the second sleeve 7 is rotated using the handle 9. In this way, when the first sleeve 6 and the second sleeve 7 are screwed together, the handle 9 is held and the second sleeve 7 is rotated, so that the construction of the ventilation sleeve 5 to the ventilation port is simplified. .

　そうすると、第２円筒部７ａのねじ山１０の開始位置と第１円筒部６ａのねじ山開始位置とが一致し、第２スリーブ７の回転とともに第１ねじ部６ｃと第２ねじ部７ｃとが螺合する。すなわち、第２マーク１３と第１マーク１２とはねじの位置を合わせる。そのため、第１ねじ部６ｃと第２ねじ部７ｃとが空回りすることなく螺合する。 Then, the starting position of the screw thread 10 of the second cylindrical part 7a coincides with the screw thread starting position of the first cylindrical part 6a, and the first screw part 6c and the second screw part 7c move together with the rotation of the second sleeve 7. Screw together. That is, the second mark 13 and the first mark 12 are aligned with each other. Therefore, the first screw portion 6c and the second screw portion 7c are screwed together without idling.

　第１円筒部６ａの外周面６ｅと孔２の内周面との間には、孔用リブ１５の高さの空間部が形成されている。そして図１に示すように、第２スリーブ７の回転を続けると、第１円筒部６ａの外周面６ｅと孔２の内周面との間の空間部に、第２スリーブ７が挿入されていく。すなわち、第２スリーブ７が孔２に当たることなく収納されていく。第２フランジ７ｂが壁１にあたって保持されると、屋内３側と屋外４側とを連通する換気経路が形成され、換気用スリーブ５が簡単に建物の壁１に施工される。 Between the outer peripheral surface 6e of the first cylindrical portion 6a and the inner peripheral surface of the hole 2, a space portion having a height of the hole rib 15 is formed. As shown in FIG. 1, when the second sleeve 7 continues to rotate, the second sleeve 7 is inserted into the space between the outer peripheral surface 6e of the first cylindrical portion 6a and the inner peripheral surface of the hole 2. Go. That is, the second sleeve 7 is stored without hitting the hole 2. If the 2nd flange 7b is hold | maintained in the wall 1, the ventilation path which connects the indoor 3 side and the outdoor 4 side will be formed, and the sleeve 5 for ventilation will be easily constructed in the wall 1 of a building.

　なお取っ手９は、円環部８に数本の角柱を突き出すようにして形成したが、円柱状でもよく、第２スリーブ７が手によって回転させやすければよい。また、第２スリーブ７に嵌合する回転治具を別品とし用意し、この回転治具を第２スリーブ７に嵌めて回転させるようにしてもよい。 Note that the handle 9 is formed so that several prisms protrude from the annular portion 8, but it may be cylindrical and the second sleeve 7 may be easily rotated by hand. Alternatively, a rotating jig that fits into the second sleeve 7 may be prepared as a separate product, and this rotating jig may be fitted into the second sleeve 7 and rotated.

　第１スリーブ６と第２スリーブ７の長さは、一般的に想定される壁厚みのうち最も薄い壁１の幅寸法にあわせて施工できるように設定すればよい。そうすると、その厚みよりも厚い壁１であっても第２スリーブ７が螺合できる範囲までの厚みに対応できる。具体的には、第１スリーブ６、第２スリーブ７の寸法（円筒部の長さ）を９０ｍｍ程度とすると、１００～１５０ｍｍの壁厚に対応できる。 The lengths of the first sleeve 6 and the second sleeve 7 may be set so that construction can be performed in accordance with the width dimension of the thinnest wall 1 among generally assumed wall thicknesses. If it does so, even the wall 1 thicker than the thickness can respond | correspond to the thickness to the range which the 2nd sleeve 7 can screw together. Specifically, if the dimension of the first sleeve 6 and the second sleeve 7 (the length of the cylindrical portion) is about 90 mm, the wall thickness of 100 to 150 mm can be handled.

　第１スリーブ６と第２スリーブ７との長さは、同じにしなくても構わないが、同じにしないと壁厚に対応できる範囲は少なくなる。しかし薄い壁１に設置されるケースが少ないと判断できれば、第１スリーブ６の長さは、一般的に想定される壁厚みのうち最も薄い壁１の幅寸法よりも長くし、第２スリーブ７の長さをその壁厚とほぼ同じにしておくとよい。 The lengths of the first sleeve 6 and the second sleeve 7 do not have to be the same, but if they are not the same, the range corresponding to the wall thickness is reduced. However, if it can be determined that the number of cases installed on the thin wall 1 is small, the length of the first sleeve 6 is made longer than the width dimension of the thinnest wall 1 among the generally assumed wall thicknesses, and the second sleeve 7. It is good to keep the length of the wall approximately the same as its wall thickness.

　また図３に示すように第２ねじ部７ｃの長さＬ２は、第２円筒部７ａの内周面７ｄの一端部に１～５ねじ山ピッチ程度にて形成されている。したがって、第１円筒部６ａ外周面６ｅに長さＬ１に渡って形成された第１ねじ部６ｃの範囲において第２スリーブ７は移動する。しかし、螺合する第１ねじ部６ｃと第２ねじ部７ｃとの長さが同じであるため、回動させる力が一定であり、施工性がよい。 As shown in FIG. 3, the length L2 of the second screw portion 7c is formed at one end of the inner peripheral surface 7d of the second cylindrical portion 7a with a pitch of about 1 to 5 thread. Therefore, the second sleeve 7 moves in the range of the first screw portion 6c formed over the length L1 on the outer peripheral surface 6e of the first cylindrical portion 6a. However, since the lengths of the first screw portion 6c and the second screw portion 7c to be screwed are the same, the rotating force is constant and the workability is good.

　また図４に示すように、第２ねじ部７ｃを形成するねじ山１０は、ねじ山１０ａ、１０ｂ・・と不連続なねじ部により形成され、軸１１方向から見た場合に第２ねじ部７ｃのねじ山１０ａ、１０ｂ・・が重ならない。そのため、第２円筒部７ａを金型により成形する場合、金型のスライド方向を軸１１方向にすれば、たとえばスライドコアーなどの複雑な金型構成を講じる必要もなく、安価に第２円筒部７ａが成形される。 As shown in FIG. 4, the screw thread 10 forming the second screw portion 7 c is formed by screw portions discontinuous with the screw threads 10 a, 10 b, and the second screw portion when viewed from the direction of the axis 11. Threads 10a, 10b ... of 7c do not overlap. Therefore, when the second cylindrical portion 7a is formed by a mold, if the mold slide direction is set to the direction of the axis 11, there is no need to provide a complicated mold configuration such as a slide core, and the second cylindrical portion can be manufactured at low cost. 7a is molded.

　また、上記構成において、第１円筒部６ａの内周面６ｄの下部１４ａは、屋外４側に向かい下り勾配θの傾斜となっている。同様に、第２円筒部７ａの内周面７ｄの下部１４ｂも、屋外４側に向かい下り勾配θの傾斜となっている。これにより、屋内３側又は屋外４側から第１スリーブ６内に侵入した水は、第１スリーブ６端部から第２スリーブ７内に流れる。さらに、第２円筒部７ａの内周面７ｄに設けられた勾配により、第２スリーブ７端部から屋外４へ排水される。 Further, in the above configuration, the lower portion 14a of the inner peripheral surface 6d of the first cylindrical portion 6a has an inclination of a downward gradient θ toward the outdoor 4 side. Similarly, the lower part 14b of the inner peripheral surface 7d of the second cylindrical part 7a is also inclined toward the outdoor 4 side with a downward gradient θ. Thereby, the water that has entered the first sleeve 6 from the indoor 3 side or the outdoor 4 side flows into the second sleeve 7 from the end of the first sleeve 6. Further, due to the gradient provided on the inner peripheral surface 7d of the second cylindrical portion 7a, the water is discharged from the end of the second sleeve 7 to the outdoors 4.

　また、孔２の孔径は孔用リブ１５の外周寸法Ｄ１である。本実施の形態１では、屋内３側から第１スリーブ６を孔２に挿入し、第１フランジ６ｂに設けたねじ孔１６を使い、ねじ（図省略）により第１フランジ６ｂを壁１に固定する。この状態において、第１円筒部６ａはその外周面６ｅに数箇所形成された孔用リブ１５により、孔２の一方に偏ることなく、ほぼ孔２の中央部に位置する。つまり、第１円筒部６ａの外周面６ｅと孔２との間には、孔用リブ１５の高さの空間が形成されている。 Further, the hole diameter of the hole 2 is the outer peripheral dimension D1 of the hole rib 15. In the first embodiment, the first sleeve 6 is inserted into the hole 2 from the indoor 3 side, the screw hole 16 provided in the first flange 6b is used, and the first flange 6b is fixed to the wall 1 by screws (not shown). To do. In this state, the first cylindrical portion 6 a is positioned substantially at the center of the hole 2 without being biased to one of the holes 2 by the hole ribs 15 formed at several locations on the outer peripheral surface 6 e. That is, a space having a height of the hole rib 15 is formed between the outer peripheral surface 6 e of the first cylindrical portion 6 a and the hole 2.

　なお、孔用リブ１５の第１フランジ６ｂ側に切り込み２４が設けられ、孔用リブ１５の径方向の高さが調整できるようにしても良い。すなわち孔用リブ１５は、第１フランジ６ｂと第１円筒部６ａとに接するように設けられているが、第１フランジ６ｂと接する部分に外周方向から切り込み２４が入れられる。このような構成であれば、孔用リブ１５の外周側は折られる、または切り取られ、その外周側の頂点と第１円筒部６ａの中心軸からの距離が変えられる。従って、建物の壁１に設けた孔２の開口寸法に多少狂いが生じてもガタツキの無い換気用スリーブ５の施工が可能となる。 A notch 24 may be provided on the first flange 6b side of the hole rib 15 so that the radial height of the hole rib 15 can be adjusted. That is, the hole rib 15 is provided so as to be in contact with the first flange 6b and the first cylindrical portion 6a, but the notch 24 is cut from the outer peripheral direction in a portion in contact with the first flange 6b. If it is such a structure, the outer peripheral side of the rib 15 for holes will be folded or cut off, and the distance from the vertex of the outer peripheral side and the central axis of the 1st cylindrical part 6a will be changed. Therefore, even if the opening dimension of the hole 2 provided in the wall 1 of the building is somewhat out of order, the ventilation sleeve 5 can be constructed without any backlash.

　（実施の形態２）
　図５は、本発明の実施の形態２の換気用スリーブの断面図である。図５に示すように、建物の壁１に換気口となる孔２が開口されている。屋内３と屋外４とは、孔２により連通されている。そして、孔２に換気用スリーブ５が施工されている。 (Embodiment 2)
FIG. 5 is a cross-sectional view of a ventilation sleeve according to Embodiment 2 of the present invention. As shown in FIG. 5, a hole 2 serving as a ventilation opening is opened in a wall 1 of a building. The indoor 3 and the outdoor 4 are communicated with each other through the hole 2. A ventilation sleeve 5 is installed in the hole 2.

　換気用スリーブ５は第１スリーブ１８と、第２スリーブ１９とから構成される。ここで第１スリーブ１８は、第１円筒部１８ａと第１円筒部１８ａの端部に形成された第１フランジ１８ｂとから構成される。また第２スリーブ１９は、第２円筒部１９ａと第２フランジ１９ｂとから構成される。 The ventilation sleeve 5 includes a first sleeve 18 and a second sleeve 19. Here, the first sleeve 18 includes a first cylindrical portion 18a and a first flange 18b formed at the end of the first cylindrical portion 18a. The second sleeve 19 includes a second cylindrical portion 19a and a second flange 19b.

　そして第１円筒部１８ａの内周面１８ｄには、第１ねじ部１８ｃが形成されている。第２円筒部１９ａの外周面１９ｅには、第２ねじ部１９ｃが形成されている。第１ねじ部１８ｃと第２ねじ部１９ｃとは螺合し、第１スリーブ１８が外側、第２スリーブ１９が内側の２重となった換気用スリーブ５が構成される。また、第１フランジ１８ｂはねじ２２により壁１に固定されている。 And the 1st thread part 18c is formed in the internal peripheral surface 18d of the 1st cylindrical part 18a. A second screw portion 19c is formed on the outer peripheral surface 19e of the second cylindrical portion 19a. The first screw portion 18c and the second screw portion 19c are screwed together to form the ventilation sleeve 5 in which the first sleeve 18 is doubled on the outside and the second sleeve 19 is doubled on the inside. The first flange 18 b is fixed to the wall 1 with a screw 22.

　上記構成において、第１円筒部１８ａの外径Ｄ３に合わせて孔２があけられる。そして第１フランジ１８ｂが壁１にねじ２２により固定される。このようにすれば、第１円筒部１８ａの外径Ｄ３より第２円筒部１９ａの外径Ｄ４は小さいので、屋外４側の壁面から簡単に第２スリーブ１９が施工される。 In the above configuration, the hole 2 is formed in accordance with the outer diameter D3 of the first cylindrical portion 18a. The first flange 18 b is fixed to the wall 1 with screws 22. In this way, since the outer diameter D4 of the second cylindrical portion 19a is smaller than the outer diameter D3 of the first cylindrical portion 18a, the second sleeve 19 is easily constructed from the wall surface on the outdoor 4 side.

　さらに、第１スリーブ１８が壁１に固定される際、孔２から塵埃、またはコンクリート粒などの落下物が発生しても、第１ねじ部１８ｃが第１円筒部１８ａにより覆われているため、落下物が第１ねじ部１８ｃに付着しない。そのため、第２ねじ部１９ｃが第１ねじ部１８ｃに螺合されるとき、落下物による支障が発生しにくくなる。 Further, when the first sleeve 18 is fixed to the wall 1, even if a falling object such as dust or concrete particles is generated from the hole 2, the first screw portion 18 c is covered with the first cylindrical portion 18 a. The fallen object does not adhere to the first screw portion 18c. For this reason, when the second screw portion 19c is screwed to the first screw portion 18c, troubles due to falling objects are less likely to occur.

　（実施の形態３）
　本発明の実施の形態３では、実施の形態１と同じ構成要素については同一の符号を付し、その詳細な説明は省略する。図６は、本発明の実施の形態３の換気用スリーブの分解斜視図である。図６に示すように円形溝２３は、第２フランジ７ｂにおいて第２円筒部７ａの中心軸７ｆが円心である。ここで円形溝２３は、屋内３と屋外４とを隔てる壁の屋外４側に設けた第１スリーブ６もしくは第２スリーブ７のどちらかのフランジに、屋外４側に設けた第１スリーブ６もしくは第２スリーブ７の中心軸７ｆを円心として設けられている。さらに、第２フランジ７ｂの外周側と円形溝２３とが接続されるように、第２フランジ７ｂには切り込み３３が設けられている。 (Embodiment 3)
In the third embodiment of the present invention, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. FIG. 6 is an exploded perspective view of the ventilation sleeve according to the third embodiment of the present invention. As shown in FIG. 6, in the circular groove 23, the central axis 7f of the second cylindrical portion 7a is the center of the second flange 7b. Here, the circular groove 23 is formed on the flange of either the first sleeve 6 or the second sleeve 7 provided on the outdoor 4 side of the wall separating the indoor 3 and the outdoor 4, and the first sleeve 6 provided on the outdoor 4 side or The central axis 7f of the second sleeve 7 is provided as a circle center. Furthermore, a cut 33 is provided in the second flange 7b so that the outer peripheral side of the second flange 7b and the circular groove 23 are connected.

　図７は、本発明の実施の形態３の換気用スリーブの形状を説明する図である。図６、図７に示すように屋外４側に設けた第２フランジ７ｂには、屋外４側に向けて突出する円環部８が設けられている。また、屋外フード２５は、円環部８とほぼ大きさが同じ額部２６を有し、額部２６の中央には開口２７が設けられている。ここで額部２６は、円環部８に契合されている。また屋外フード２５は、回動可能である。そして円環部８は、屋外４側に設けた第１スリーブ６もしくは第２スリーブ７のどちらかのフランジに設けられている。開口２７は格子状の網、あるいは格子状の桟が設けられている。さらに、開口２７は丸型カバー部２８により屋外４側が覆われ、水平方向の開口２７と垂直方向の下部開口部２９とが連通している。 FIG. 7 is a diagram illustrating the shape of the ventilation sleeve according to the third embodiment of the present invention. As shown in FIGS. 6 and 7, the second flange 7 b provided on the outdoor 4 side is provided with an annular portion 8 that protrudes toward the outdoor 4 side. The outdoor hood 25 has a forehead portion 26 that is substantially the same size as the annular portion 8, and an opening 27 is provided in the center of the forehead portion 26. Here, the forehead portion 26 is engaged with the annular portion 8. The outdoor hood 25 is rotatable. The annular portion 8 is provided on the flange of either the first sleeve 6 or the second sleeve 7 provided on the outdoor 4 side. The opening 27 is provided with a lattice-like net or a lattice-like crosspiece. Further, the opening 27 is covered by the round cover portion 28 on the outdoor 4 side, and the horizontal opening 27 and the vertical lower opening 29 communicate with each other.

　また額部２６には、円心方向に向かって突出した屋外フード嵌合爪３０が設けられている。そして円環部８の外周側には、屋外フード嵌合爪３０を係合するためのフード用溝３１が設けられている。 Further, the forehead portion 26 is provided with an outdoor hood fitting claw 30 that protrudes toward the center of the circle. A hood groove 31 for engaging the outdoor hood fitting claw 30 is provided on the outer peripheral side of the annular portion 8.

　上記構成において、第２スリーブ７が回転されて、第２円筒部７ａの内側に第１スリーブ６が挿入される。第２スリーブ７が壁１にあたって保持されると、屋内３側と屋外４側とを連通する換気経路が形成される。そして第２フランジ７ｂは、壁１に開口した換気口を隠して覆う機能を有するが、換気口として削り取った部分が小さいときには、円形溝２３に沿って第２フランジ７ｂの大きさを小さくすることができる。すなわち、最小面積の第２フランジ７ｂにより覆うことができる。なお、第２フランジ７ｂの外周と円形溝２３とを接続する切り込み３３は、円形溝２３を切断するときのガイドとなるため、第２フランジ７ｂは簡単に切断される。すなわち屋外４側の第２フランジ７ｂの大きさを変更する作業が行なわれる際、簡単に切り込み３３に沿って第２フランジ７ｂが切断される。 In the above configuration, the second sleeve 7 is rotated and the first sleeve 6 is inserted inside the second cylindrical portion 7a. If the 2nd sleeve 7 is hold | maintained in the wall 1, the ventilation path which connects the indoor 3 side and the outdoor 4 side will be formed. The second flange 7b has a function of concealing and covering the ventilation port opened in the wall 1, but when the portion cut off as the ventilation port is small, the size of the second flange 7b is reduced along the circular groove 23. Can do. That is, it can be covered with the second flange 7b having the minimum area. In addition, since the notch 33 that connects the outer periphery of the second flange 7b and the circular groove 23 serves as a guide for cutting the circular groove 23, the second flange 7b is easily cut. That is, when the work of changing the size of the second flange 7 b on the outdoor 4 side is performed, the second flange 7 b is easily cut along the notch 33.

　また円環部８の外周に、屋外フード２５の額部２６が引掛けられるように取り付けられる。その結果、屋外フード２５は、第２円筒部７ａの開口部の周囲に回転可能となる。従って、第２スリーブ７がどの位置に固定されても、屋外フード２５は所望の位置に固定される。下部開口部２９が下向きに開口しているので、丸型カバー部２８が雨を遮り、屋外４からの雨水が換気用スリーブ５内に浸入することが防止される。 Moreover, it attaches so that the forehead part 26 of the outdoor hood 25 may be hooked on the outer periphery of the annular part 8. As a result, the outdoor hood 25 can rotate around the opening of the second cylindrical portion 7a. Therefore, the outdoor hood 25 is fixed at a desired position no matter where the second sleeve 7 is fixed. Since the lower opening 29 opens downward, the round cover portion 28 blocks rain, and rainwater from the outdoors 4 is prevented from entering the ventilation sleeve 5.

　また額部２６には、壁面から突出した水切り部３２が設けられている。水切り部３２は、屋外フード２５の下側に位置するように施工される。そのため、屋外フード２５の額部２６を伝う雨水は、水切り部３２へと伝って流れ、壁１面から離れた水切り部３２の最下部から滴下することになる。その結果、第２フランジ７ｂの下側を集中して雨水が流れることによる壁面の汚れが低減される。 The forehead portion 26 is provided with a draining portion 32 protruding from the wall surface. The draining part 32 is constructed so as to be positioned below the outdoor hood 25. Therefore, rainwater that travels along the forehead portion 26 of the outdoor hood 25 flows to the draining portion 32 and drops from the lowermost portion of the draining portion 32 that is away from the wall 1 surface. As a result, the contamination of the wall surface due to the rainwater flowing concentrated on the lower side of the second flange 7b is reduced.

　また、屋外４に露出する屋外フード２５、又は屋外フード２５と第２スリーブ７の材料が鉄であると、紫外線による劣化がより軽減できる。 Further, when the outdoor hood 25 exposed to the outdoor 4 or the material of the outdoor hood 25 and the second sleeve 7 is iron, deterioration due to ultraviolet rays can be further reduced.

　図８に示すように本実施の形態４の換気用スリーブ５は、第１円筒部６ａの端部におよび第１フランジ６ｂを有する第１スリーブ６と、第２円筒部７ａおよび第２フランジ７ｂを有する第２スリーブ７とから構成される。第２円筒部７ａの一端部の外周には、第２フランジ７ｂの位置決めを行う突出縁４１と取っ手４２が形成されている。第２フランジ７ｂには、第２円筒部７ａに嵌り合う円形の第２フランジ内孔４３が形成されている。第２スリーブ７は、突出縁８を設けた端部と反対側の第２円筒部７ａの端部が内孔４３に挿入され、突出縁８に第２フランジ７ｂが当接される。 As shown in FIG. 8, the ventilation sleeve 5 of the fourth embodiment includes a first sleeve 6 having a first flange 6b at the end of the first cylinder 6a, a second cylinder 7a and a second flange 7b. And a second sleeve 7 having A projecting edge 41 and a handle 42 for positioning the second flange 7b are formed on the outer periphery of one end of the second cylindrical portion 7a. The second flange 7b is formed with a circular second flange inner hole 43 that fits into the second cylindrical portion 7a. In the second sleeve 7, the end of the second cylindrical portion 7 a opposite to the end provided with the protruding edge 8 is inserted into the inner hole 43, and the second flange 7 b is in contact with the protruding edge 8.

　なお本実施の形態４では、屋内３と屋外４とを隔てる壁１の屋内３側に第１スリーブ６が配置されている。また第２フランジ７ｂは、周方向４４に回動可能である。 In the fourth embodiment, the first sleeve 6 is arranged on the indoor 3 side of the wall 1 separating the indoor 3 and the outdoor 4. Further, the second flange 7 b is rotatable in the circumferential direction 44.

　図９、図１０に示すように第２フランジ７ｂの上部には、屋外４側にむかって突出した屋外フード掛け爪３４が設けられている。また第２フランジ７ｂの下部には、壁１から突出した水切り部３２と第２フランジ７ｂとを固定するねじ孔３５が設けられている。屋外フード２５の上部には、屋外フード掛け爪３４が嵌るフード掛け部３６が形成されている。屋外フード２５の下部には、ねじ孔３５に一致する箇所にフード固定孔３７が設けられている。また、屋外フード２５のカバー部３８内部には、屋外フード２５を第２フランジ７ｂに取付けたとき、その先端位置が第２円筒部７ａの屋外側面３９に一致するように形成した押さえリブ４０が設けられている。 As shown in FIGS. 9 and 10, an outdoor hood hanging claw 34 protruding toward the outdoor 4 side is provided on the upper portion of the second flange 7b. A screw hole 35 for fixing the draining portion 32 protruding from the wall 1 and the second flange 7b is provided at the lower portion of the second flange 7b. In the upper part of the outdoor hood 25, a hood hooking portion 36 into which the outdoor hood hooking claws 34 are fitted is formed. At the lower part of the outdoor hood 25, a hood fixing hole 37 is provided at a location corresponding to the screw hole 35. In addition, inside the cover portion 38 of the outdoor hood 25, there is a holding rib 40 formed so that when the outdoor hood 25 is attached to the second flange 7b, the tip position thereof coincides with the outdoor side surface 39 of the second cylindrical portion 7a. Is provided.

　押さえリブ４０は、屋外フード２５の位置決めを行う。上記構成において、第２円筒部７ａが回転されて、第２スリーブ７の内側に第１スリーブ６が挿入され、第２フランジ７ｂが保持されると、屋内３側と屋外４側とを連通する換気経路が形成される。このとき第２フランジ７ｂは回転可能であるので、屋外フード掛け爪３４が最上部になるように位置が調整される。そして、屋外フード掛け爪３４にフード掛け部３６を引っ掛けて屋外フード２５が取り付けられ、フード固定孔３７とねじ孔３５とがネジ５２により壁１に固定される。このように換気用スリーブ５が、簡単に建物の壁１に施工され屋外フード２５が簡単に取付けられる。そして、下部開口部２９が下向きに開口しているので、カバー部３８が雨を遮り、屋外４からの雨水の換気用スリーブ５内への浸入が防止される。 The holding rib 40 positions the outdoor hood 25. In the above configuration, when the second cylindrical portion 7a is rotated, the first sleeve 6 is inserted inside the second sleeve 7 and the second flange 7b is held, the indoor 3 side and the outdoor 4 side are communicated. A ventilation path is formed. Since the 2nd flange 7b can rotate at this time, a position is adjusted so that the outdoor hood hooking claw 34 may become the uppermost part. Then, the outdoor hood 25 is attached by hooking the hood hanging portion 36 on the outdoor hood hanging claw 34, and the hood fixing hole 37 and the screw hole 35 are fixed to the wall 1 by screws 52. In this way, the ventilation sleeve 5 is simply constructed on the wall 1 of the building, and the outdoor hood 25 is easily attached. Since the lower opening 29 opens downward, the cover 38 blocks rain, and rainwater from the outdoor 4 can be prevented from entering the ventilation sleeve 5.

　また、屋外フード２５が壁１に固定されると、押さえリブ４０の先端位置が第２フランジ７ｂの屋外側面３９に一致する。すなわち、押さえリブ４０が第２円筒部７ａの一端部の外周に当たり、第１スリーブ６と第２スリーブ７との螺合が緩んで、第２スリーブ７が屋外４側に出てくることが防止される。 Further, when the outdoor hood 25 is fixed to the wall 1, the tip position of the holding rib 40 coincides with the outdoor side surface 39 of the second flange 7b. That is, the holding rib 40 hits the outer periphery of the one end portion of the second cylindrical portion 7a, and the screwing between the first sleeve 6 and the second sleeve 7 is loosened to prevent the second sleeve 7 from coming out to the outdoor 4 side. Is done.

　本発明の換気用スリーブは、壁を貫通する換気装置のみならず、空気調和機などのダクト施工、配管施工に用いることができる。 The ventilation sleeve of the present invention can be used not only for ventilation devices penetrating walls, but also for duct construction and piping construction for air conditioners and the like.
