【発明の属する技術分野】
本発明は、樋などの接続部材に関するものである。
【０００２】
【従来の技術】
従来、例えば、玄関庇のドレン落とし部から袖壁外側にある排水口に縦樋を施工する場合、図６に示すように、縦樋の角度を変更する箇所が４箇所発生する。これらの角度を変更する箇所には、エルボ１１と、受け口部１２１および該受け口部１２１に対して受け口部１２１の軸心と直交する軸心回りに回転自在な挿し口部１２２からなるターンエルボ１２（図７参照）が採用される。具体的には、横方向から縦方向への振り施工にターンエルボ１２が使用され、水勾配のための縦方向から横方向への振り施工にエルボ１１が使用される。
【０００３】
ここで、ターンエルボ１２は、部品間違えや、紛失を防止するため、受け口部１２１と挿し口部１２２が不離一体に接続されている。
【０００４】
このように、各変角箇所にエルボ１１およびターンエルボ１２をそれぞれ採用すると、使用する部品の種類が複数になるとともに、接続箇所が多くなり、接続作業が煩雑になるという欠点があった。
【０００５】
一方、図８に示すように、横方向から横方向の振り施工にターンエルボ１２を採用すれば、接続箇所を３箇所に削減することができ、その分、接続作業を簡単に行うことができる。
【０００６】
【発明が解決しようとする課題】
しかしながら、ターンエルボ１２は、受け口部１２１に対して挿し口部１２２が回転自在に装着されている関係上、それらの回転接続部に隙間を有している。このため、挿し口部１２２に水が溜まる場合、例えば、図９（ａ）に示すように、挿し口部１２２の軸心が横方向に指向する場合や、ターンエルボ１２を上下逆に使用する場合、例えば、図９（ｂ）に示すように、挿し口部１２２が水上側に、受け口部１２１が水下側にそれぞれ位置する場合、受け口部１２１と挿し口部１２２との回転接続部から漏水するという問題がある。
【０００７】
したがって、図８に示したように、ターンエルボ１２を横方向から横方向の振り施工に使用することはできない。この結果、ターンエルボ１２の使用部位および使用方法が限定されることから、必ずしも接続箇所を削減することはできず、縦樋などの接続作業を簡単に行うことはできない。また、エルボ１１とターンエルボ１２の２種類の接続部材を使用しなければならず、接続部材の選択を誤るなどの誤作業を発生し易いという問題も解消できないものである。
【０００８】
本発明は、このような問題点に鑑みてなされたものであり、縦樋などの変角箇所において、振り角を調整しつつ、水漏れの発生を確実に防止して接続作業を簡単に行うことのできる接続部材を提供するものである。
【０００９】
【課題を解決するための手段】
本発明は、一端に配管の接続口を有する受け部材と、一端に配管の接続口を有する挿し部材と、からなり、受け部材または挿し部材の一方に接続部が形成されるとともに、他方に接続部に対応して被接続部が形成され、受け部材に対する挿し部材の振り角を調節して、受け部材および挿し部材の接続部および被接続部が着脱自在に嵌挿されるとともに、嵌挿された接続部および被接続部が全周にわたって接着剤を介して密封されていることを特徴とするものである。
【００１０】
本発明において、受け部材および挿し部材の形状は、通常断面略円形に形成されるが、デザイン性などの観点から円形以外であってもかまわない。例えば、断面方形の配管部材が採用されたならば、その配管部材を接続できる接続口を有する断面形状に形成すればよい。
【００１１】
本発明において、受け部材の接続口および挿し部材の接続口は、それぞれ受け口であっても、挿し口であってもよい。
【００１２】
本発明において、受け部材および挿し部材の接続部および被接続部の形状は、受け部材に対する挿し部材の振り角を無段階に調整できることから、通常断面円形に形成されるが、振り角を必ずしも無段階に調整する必要がない場合には、多角形状であってもよい。
【００１３】
本発明において、受け部材および挿し部材は、その外周面が直線上に延びる直管形状であってもよいし、配管部材との接続態様を考慮して変角部を有する屈曲されたものであってもかまわない。
【００１４】
本発明によれば、受け部材および挿し部材の接続部および被接続部を嵌挿し、受け部材に対する挿し部材の振り角を調整した後、接続部および／または被接続部に接着剤を塗布し、受け部材および挿し部材の接続部および被接続部を嵌挿すれば、両者を接続することができる。
【００１５】
なお、受け部材の受け口および挿し部材の挿し口には、振り角を調整して配管などが嵌挿して接続される。
【００１６】
この結果、縦樋を施工する際、変角箇所に同一の接続部材を用いて施工できることから、接続作業を標準化することができる。また、受け部材および挿し部材の接続部および被接続部は接着剤を介して嵌挿接続されていることから、両者は、全周にわたって密封され、接続部と被接続部との嵌挿部分から水漏れが発生するのを確実に防止することができる。このため、接続部材の使用部位および使用方法が限定されないことから、変角箇所を削減することが可能となり、接続作業を簡単に行うことができる。
【００１７】
また、本発明は、一端に配管の接続口を有する受け部材と、一端に配管の接続口を有する挿し部材と、からなり、受け部材または挿し部材の一方に接続部が形成されるとともに、他方に接続部に対応して被接続部が形成され、また、接続部または被接続部の少なくとも一方に水密部材が設けられ、受け部材に対する挿し部材の振り角を調節して、受け部材および挿し部材の接続部および被接続部が着脱自在に嵌挿されるとともに、嵌挿された接続部および被接続部が水密部材を介して密封されていることを特徴とするものである。
【００１８】
本発明において、受け部材および挿し部材の形状は、通常断面略円形に形成されるが、デザイン性などの観点から円形以外であってもかまわない。例えば、断面方形の配管部材が採用されたならば、その配管部材を接続できる接続口を有する断面形状に形成すればよい。
【００１９】
本発明において、受け部材の接続口および挿し部材の接続口は、それぞれ受け口であっても、挿し口であってもよい。
【００２０】
本発明において、受け部材および挿し部材の接続部および被接続部の形状は、受け部材に対する挿し部材の振り角を無段階に調整できることから、通常断面円形に形成されるが、振り角を必ずしも無段階に調整する必要がない場合には、多角形状であってもよい。
【００２１】
本発明において、受け部材および挿し部材は、その外周面が直線上に延びる直管形状であってもよいし、配管部材との接続態様を考慮して変角部を有する屈曲されたものであってもかまわない。
【００２２】
本発明によれば、受け部材および挿し部材の接続部および被接続部を嵌挿すれば、接続部と被接続部が水密部材を介して密封される。
【００２３】
なお、受け部材に対する挿し部材の振り角は、受け部材に対して挿し部材を回転することで調整できる。
【００２４】
また、受け部材の受け口および挿し部材の挿し口には、振り角を調整して配管などが嵌挿して接続される。
【００２５】
この結果、縦樋を施工する際、変角箇所に同一の接続部材を用いて施工できることから、接続作業を標準化することができる。また、受け部材および挿し部材の接続部および被接続部は水密部材を介して嵌挿されていることから、両者は、全周にわたって密封され、接続部と被接続部との嵌挿部分から水漏れが発生するのを確実に防止することができる。このため、接続部材の使用部位および使用方法が限定されないことから、変角箇所を削減することが可能となり、接続作業を簡単に行うことができる。
【００２６】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。
【００２７】
図１には、本発明の接続部材１の一実施形態が示されている。
【００２８】
この接続部材１は、一端に断面略楕円状の配管の受け口４を有する受け部材２と、一端に断面略楕円状の配管の挿し口５を有する挿し部材３と、から構成されている。そして、受け部材２の他端には、接続部６が形成されるとともに、挿し部材３の他端には、受け部材２の接続部６に対応して被接続部７が形成されている。具体的には、受け部材２の接続部６は、他端開口から突出された断面円形の筒状部６Ａに半径方向に設定間隔をおいて２条の周溝６ａと３本の周壁６ｂを円周方向に形成したものである。また、挿し部材３の被接続部７は、その他端開口端面に半径方向に設定間隔をおいて２条の周溝７ａと３本の周壁７ｂを円周方向に形成したものである。ここで、受け部材２の周溝６ａに挿し部材３の周壁７ｂが嵌挿され、また、挿し部材３の周溝７ａに受け部材２の周壁６ｂが嵌挿されるように、受け部材２の周溝６ａと周壁６ｂおよび挿し部材３の周溝７ａと周壁７ｂの形成位置が設定されている。
【００２９】
次に、このように構成された接続部材１を用いて縦樋を施工する場合について、図２に基づいて説明する。
【００３０】
ドレン落とし部に一端部が接続された配管Ｐ１の他端部に受け部材２の受け口４を嵌挿して接続する。この際、配管Ｐ１に対して受け部材２の振り角を調整する。次いで、受け部材２の接続部６に、挿し部材３の被接続部７を嵌挿し、受け部材２に対する挿し部材３の振り角を調整する。両者の振り角の調整が終了すれば、受け部材２の周溝６ａおよび／または挿し部材３の周溝７ａの全周にわたってに接着剤を充填し、再び受け部材２の接続部６に挿し部材３の被接続部７を嵌挿し、接続する。この際、受け部材２に対する調整された挿し部材３の振り角が変化しないように、受け部材２および挿し部材３にわたってマーキングを付すことが好ましい。
【００３１】
次いで、挿し部材３の挿し口５に配管Ｐ２を嵌挿して接続した後、配管Ｐ２の他端部に受け部材２の受け口４を嵌挿し、配管Ｐ２に対する受け部材２の振り角を調整して接続する。次いで、受け部材２の接続部６に、挿し部材３の被接続部７を嵌挿し、受け部材２に対する挿し部材３の振り角を調整した後、受け部材２の周溝６ａおよび／または挿し部材３の周溝７ａに接着剤を充填し、受け部材２の接続部６に挿し部材３の被接続部７を嵌挿し、接続する。
【００３２】
以下、同様に、挿し部材３の挿し口５に配管Ｐ３を嵌挿して接続した後、配管Ｐ３の他端部に受け部材２の受け口４を嵌挿し、配管Ｐ３に対する受け部材２の振り角を調整して接続する。次いで、受け部材２の接続部６に、挿し部材３の被接続部７を嵌挿し、受け部材２に対する挿し部材３の振り角を調整した後、受け部材２の周溝６ａおよび／または挿し部材３の周溝７ａに接着剤を充填し、受け部材２の接続部６に挿し部材３の被接続部７を嵌挿し、接続する。その後、挿し部材３の挿し口５に配管Ｐ４を嵌挿して接続すれば、図示しない排水口に縦樋を導くことができる。
【００３３】
この結果、縦樋を施工する際、変角箇所に同一の接続部材１を用いて施工できることから、接続作業を標準化することができる。また、受け部材２の接続部６を構成する周溝６ａおよび／または挿し部材３の被接続部７を構成する周溝７ａの全周にわたって接着剤が充填されるとともに、受け部材２の接続部６および挿し部材３の被接続部７が嵌挿されていることから、両者は、接着剤により全周にわたって密封され、接続部６と被接続部７との嵌挿部分から水漏れが発生するのを確実に防止することができる。このため、接続部材１の使用部位および使用方法が限定されないことから、変角箇所を削減することが可能となり、接続作業を簡単に行うことができる。
【００３４】
図３には、本発明の接続部材１の他の実施形態が示されている。
【００３５】
この接続部材１も、一端に配管の受け口４を有する受け部材２と、一端に配管の挿し口５を有する挿し部材３と、からなり、図１に示した接続部材１の接続部６および被接続部７と略同一の接続部６および被接続部７を有している。
【００３６】
すなわち、受け部材２の接続部６は、その他端開口から突出された筒状部６Ａに半径方向に設定間隔をおいて２条の周溝６ａと３本の周壁６ｂを形成して構成され、挿し部材３の被接続部７は、接続部６の周溝６ａに嵌挿される周壁７ａと、接続部６の周壁６ａが嵌挿される周溝７ｂを形成して構成されている。そして、受け部材２における接続部６の周壁６ｂの先端に、周壁６ｂの幅よりも大きな突起６ｂ−１が形成され、また、挿し部材３の被接続部７の周溝７ｂの底部に、前述の突起６ｂ−１に対応して、周溝７ｂの幅よりも大きな空洞７ｂ−１が形成されている。
【００３７】
一方、受け部材２の接続部６を構成する少なくとも１本の周溝６ａの底面には、Ｏリングなどのシール部材（水密部材）Ｓが装着されている。
【００３８】
したがって、受け部材２の接続部６に、挿し部材３の被接続部７を嵌挿すれば、受け部材２の周溝６ａに挿し部材３の周壁７ｂが嵌挿されるとともに、受け部材２の周壁６ｂが挿し部材３の周溝７ａに嵌挿され、その際、両者は、シール部材Ｓによって密封される。
【００３９】
すなわち、詳細には図示しないが、ドレン落とし部に一端部が接続された配管の他端部に受け部材２の受け口４を嵌挿して接続した後、受け部材２の接続部６に、挿し部材３の被接続部７を嵌挿すれば、受け部材２の周溝６ａに挿し部材３の周壁７ｂが、また、挿し部材３の周溝７ａに受け部材２の周壁６ｂがそれぞれシール部材Ｓを介して密封された状態で嵌挿される。
【００４０】
この場合、受け部材２に対する挿し部材３の振り角は、受け部材２に対して挿し部材３を回転することで調整できる。
【００４１】
以下同様に、順に挿し部材３の挿し口５に配管を接続し、その他端部に受け部材２の受け口４を接続した後、受け部材２の接続部６に、挿し部材３の被接続部７を嵌挿すればよいものである。
【００４２】
この実施形態においても、縦樋を施工する際、変角箇所に同一の接続部材１を用いて施工できることから、接続作業を標準化することができる。また、受け部材２の接続部６と、挿し部材３の被接続部７とは、シール部材Ｓを介して嵌挿されることから、両者は、全周にわたって密封され、接続部６と被接続部７との嵌挿部分から水漏れが発生するのを確実に防止することができる。このため、接続部材１の使用部位および使用方法が限定されないことから、変角箇所を削減することが可能となり、接続作業を簡単に行うことができる。
【００４３】
図４には、本発明の接続部材１のもう一つの実施形態が示されている。
【００４４】
この接続部材１も、一端に配管の受け口４を有する受け部材２と、一端に配管の挿し口５を有する挿し部材３と、からなり、受け部材２の接続部６は、他端開口から突出された筒状部６Ａの外周面にその軸心と平行にスプライン状の歯６ｃ（図５参照）を形成して構成され、また、挿し部材３の被接続部７は、接続部６の歯６ｃに噛み合う溝７ｃを形成して構成されている。
【００４５】
したがって、受け部材２の接続部６に、挿し部材３の被接続部７を嵌挿すれば、受け部材２の歯６ｃに挿し部材３の溝７ｃが噛み合って嵌挿される。この際、受け部材２の歯６ｃおよび／または挿し部材３の溝７ｃの全周にわたって接着剤を塗布すれば、受け部材２の歯６ｃおよび挿し部材３の溝７ｃが噛み合って嵌挿されることにより、両者は、接着剤によって全周にわたって密封される。
【００４６】
この接続部材１についても、先に説明したように、ドレン落とし部に一端部が接続された配管の他端部に受け部材２の受け口４を嵌挿して接続した後、受け部材２の接続部６に、挿し部材３の被接続部７を嵌挿すれば、受け部材２の歯６ｃに挿し部材３の溝７ｃが噛み合い、受け部材２の接続部６と挿し部材３の被接続部７が接着剤を介して密封されて接続される。
【００４７】
この場合、受け部材２に対する挿し部材３の振り角は、受け部材２の歯６ｃに対する挿し部材３の溝７ｃの噛み合い位置を変更することで調整できる。
【００４８】
以下、同様に、配管、受け部材２および挿し部材３の順に接続すればよい。
【００４９】
この実施形態においても、縦樋の各変角箇所に同一の接続部材１を用いて施工できることから、作業を標準化することができる。また、受け部材２の接続部６を構成する歯６ｃおよび／または挿し部材３の被接続部７を構成する溝７ｃの全周にわたって接着剤が塗布されるとともに、受け部材２の接続部６および挿し部材３の被接続部７が嵌挿されていることから、両者は、接着剤により全周にわたって密封され、接続部６と被接続部７との嵌挿部分から水漏れが発生するのを確実に防止することができる。このため、接続部材１の使用部位および使用方法が限定されないことから、変角箇所を削減することが可能となり、接続作業を簡単に行うことができる。
【００５０】
なお、前述した実施形態においては、受け部材２の受け口４および挿し部材３の挿し口５に接続される配管は、断面略楕円状に形成されたものを例示したが、接続される配管の断面形状に合わせて受け口４および挿し口５を形成することにより、断面円管状や角管状など、任意の形状を選択できる。
【００５１】
この場合、受け部材２の接続口を挿し口とし、挿し部材３の接続口を受け口としてもよく、また、両方を受け口あるいは挿し口としてもよい。
【００５２】
また、受け部材２および挿し部材３の接続部６および被接続部７の形状は、受け部材２に対する挿し部材７の振り角を調整できればよく、断面円形に限らず多角形状であってもよい。
【００５３】
さらに、受け部材２および挿し部材３は、直管状に限らず変角部を有する屈曲されたものであってもよい。例えば、挿し部材３において、接続部７の軸心と挿し口５の軸心とが交差するものであってもよい。
【００５４】
【発明の効果】
このように本発明によれば、縦樋などの変角箇所において、振り角を調整しつつ、水漏れの発生を確実に防止して接続作業を簡単に行うことができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a connecting member such as a gutter.
[0002]
[Prior art]
Conventionally, for example, when a downspout is constructed from a drain dropping part of an entrance eave to a drain port outside a sleeve wall, as shown in FIG. 6, there are four places where the angle of the downspout is changed. The location where these angles are changed includes an elbow 11, a receiving port 121, and a turn elbow 12 comprising an insertion port 122 rotatable around an axis perpendicular to the axis of the receiving port 121 with respect to the receiving port 121. (See FIG. 7) is employed. Specifically, the turn elbow 12 is used for swinging from a horizontal direction to a vertical direction, and the elbow 11 is used for swinging from a vertical direction to a horizontal direction due to a water gradient.
[0003]
Here, the turn elbow 12 is configured such that the receiving port 121 and the insertion port 122 are inseparably integrated with each other in order to prevent mistaken parts and loss.
[0004]
As described above, when the elbow 11 and the turn elbow 12 are used in each of the bending positions, there are disadvantages that the number of types of components to be used is increased, the number of connection points is increased, and the connection work is complicated.
[0005]
On the other hand, as shown in FIG. 8, if the turn elbow 12 is used in the swinging operation from the horizontal direction to the horizontal direction, the number of connection points can be reduced to three, and the connection operation can be performed easily accordingly. .
[0006]
[Problems to be solved by the invention]
However, since the insertion port 122 is rotatably attached to the receiving port 121, the turn elbow 12 has a gap between the rotary connection sections. Therefore, when water accumulates in the insertion port 122, for example, as shown in FIG. 9A, when the axis of the insertion port 122 is oriented in the horizontal direction, or when the turn elbow 12 is used upside down. In this case, for example, as shown in FIG. 9B, when the insertion port 122 is located on the water side and the reception port 121 is located on the water side, the rotation connection between the reception port 121 and the insertion port 122 is performed. There is a problem of water leakage.
[0007]
Therefore, as shown in FIG. 8, the turn elbow 12 cannot be used for swinging from side to side. As a result, since the use site and use method of the turn elbow 12 are limited, the number of connection portions cannot always be reduced, and connection work such as downspout cannot be easily performed. In addition, two types of connecting members, the elbow 11 and the turn elbow 12, must be used, and the problem of erroneous work such as erroneous selection of the connecting member cannot be solved.
[0008]
The present invention has been made in view of such a problem, and in a bend point such as a downspout, the swing operation is adjusted, the occurrence of water leakage is reliably prevented, and the connection operation is easily performed. It is intended to provide a connecting member capable of being operated.
[0009]
[Means for Solving the Problems]
The present invention comprises a receiving member having a pipe connection port at one end and an insertion member having a pipe connection port at one end, and a connection portion is formed on one of the receiving member or the insertion member and connected to the other. A connected portion is formed corresponding to the portion, the swing angle of the insertion member with respect to the receiving member is adjusted, and the connection portion and the connected portion of the receiving member and the insertion member are removably inserted and inserted. The connecting portion and the connected portion are sealed over the entire circumference via an adhesive.
[0010]
In the present invention, the shape of the receiving member and the inserting member is generally formed in a substantially circular cross section, but may be other than circular from the viewpoint of design and the like. For example, if a pipe member having a rectangular cross section is employed, the pipe member may be formed in a cross-sectional shape having a connection port to which the pipe member can be connected.
[0011]
In the present invention, the connection port of the receiving member and the connection port of the insertion member may each be a reception port or an insertion port.
[0012]
In the present invention, the shapes of the connecting portion and the connected portion of the receiving member and the inserting member are usually formed in a circular cross section because the swing angle of the inserting member with respect to the receiving member can be adjusted in a stepless manner. If it is not necessary to adjust in stages, it may be polygonal.
[0013]
In the present invention, the receiving member and the insertion member may have a straight pipe shape whose outer peripheral surface extends linearly, or may be bent with a bent portion in consideration of a connection mode with the piping member. It doesn't matter.
[0014]
According to the present invention, the connecting portion and the connected portion of the receiving member and the inserting member are fitted and inserted, and after adjusting the swing angle of the inserting member with respect to the receiving member, an adhesive is applied to the connecting portion and / or the connected portion, If the connecting portion and the connected portion of the receiving member and the inserting member are fitted and inserted, both can be connected.
[0015]
The swing angle is adjusted and a pipe or the like is fitted and connected to the receiving port of the receiving member and the receiving port of the insertion member.
[0016]
As a result, when the downspout is constructed, it can be constructed using the same connecting member at the bend point, so that the connecting work can be standardized. In addition, since the connecting portion and the connected portion of the receiving member and the inserting member are inserted and connected via an adhesive, both are sealed over the entire circumference, and the two portions are sealed from the inserted portion of the connecting portion and the connected portion. It is possible to reliably prevent the occurrence of water leakage. For this reason, since the use site | part and the use method of a connection member are not limited, it becomes possible to reduce a bending part and to perform connection work easily.
[0017]
Further, the present invention comprises a receiving member having a pipe connection port at one end, and an insertion member having a pipe connection port at one end, and a connection portion is formed on one of the receiving member or the insertion member, and the other. A connection portion is formed corresponding to the connection portion, a watertight member is provided on at least one of the connection portion and the connection portion, and the swing angle of the insertion member with respect to the reception member is adjusted, so that the reception member and the insertion member are provided. The connecting portion and the connected portion are removably fitted and the fitted connecting portion and the connected portion are hermetically sealed via a watertight member.
[0018]
In the present invention, the shape of the receiving member and the inserting member is generally formed in a substantially circular cross section, but may be other than circular from the viewpoint of design and the like. For example, if a pipe member having a rectangular cross section is employed, the pipe member may be formed in a cross-sectional shape having a connection port to which the pipe member can be connected.
[0019]
In the present invention, the connection port of the receiving member and the connection port of the insertion member may each be a reception port or an insertion port.
[0020]
In the present invention, the shapes of the connecting portion and the connected portion of the receiving member and the inserting member are usually formed in a circular cross section because the swing angle of the inserting member with respect to the receiving member can be adjusted in a stepless manner. If it is not necessary to adjust in stages, it may be polygonal.
[0021]
In the present invention, the receiving member and the insertion member may have a straight pipe shape whose outer peripheral surface extends linearly, or may be bent with a bent portion in consideration of a connection mode with the piping member. It doesn't matter.
[0022]
According to the present invention, when the connecting portion and the connected portion of the receiving member and the inserting member are fitted, the connecting portion and the connected portion are sealed via the watertight member.
[0023]
The swing angle of the insertion member with respect to the receiving member can be adjusted by rotating the insertion member with respect to the receiving member.
[0024]
Further, the swing angle is adjusted and a pipe or the like is inserted and connected to the receiving port of the receiving member and the receiving port of the insertion member.
[0025]
As a result, when the downspout is constructed, it can be constructed using the same connecting member at the bend point, so that the connecting work can be standardized. Further, since the connecting portion and the connected portion of the receiving member and the inserting member are fitted through the watertight member, both are sealed over the entire circumference, and the water is inserted from the fitting portion between the connecting portion and the connected portion. Leakage can be reliably prevented from occurring. For this reason, since the use site | part and the use method of a connection member are not limited, it becomes possible to reduce a bending part and to perform connection work easily.
[0026]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0027]
FIG. 1 shows an embodiment of the connecting member 1 of the present invention.
[0028]
The connecting member 1 includes a receiving member 2 having a pipe receiving port 4 having a substantially elliptical cross section at one end, and an inserting member 3 having a pipe inserting port 5 having a substantially elliptical cross section at one end. At the other end of the receiving member 2, a connecting portion 6 is formed, and at the other end of the inserting member 3, a connected portion 7 is formed corresponding to the connecting portion 6 of the receiving member 2. Specifically, the connecting portion 6 of the receiving member 2 is formed by connecting two circumferential grooves 6a and three circumferential walls 6b at a set interval in the radial direction to a cylindrical portion 6A having a circular cross section protruding from the other end opening. It is formed in the circumferential direction.
