ように構成されている。 Traditionally, pipe fittings that meet these demands have been
For example, the one shown in Japanese Utility Model Application Publication No. 54-37527 is known. This pipe joint is constructed as shown in FIG.
筒体１の内部に、その両端から互いに連結す
る２本の管体２，２の先端部を挿入する。 The tips of two tubes 2, 2 that are connected to each other are inserted into the interior of the tube 1 from both ends thereof.
前記筒体１の両端の内部には、所定の間隔を
おいてロツクリング３と環状シール材４を設け
る。 Inside both ends of the cylindrical body 1, a lock ring 3 and an annular sealing member 4 are provided at a predetermined interval.
ロツクリング３から所定の間、隔離した筒体
１の内部に段部５を設ける。 A stepped portion 5 is provided inside the cylindrical body 1 separated from the lock ring 3 by a predetermined distance.
２本の管体２，２の外周には、突部６を固着
する。 A protrusion 6 is fixed to the outer periphery of the two tube bodies 2, 2.
突部６は前記ロツクリング３と段部５との間
を移転自在である。 The protrusion 6 is movable between the lock ring 3 and the step 5.
環状シール材４は、各管体２，２の外周に密
に接触している。 The annular sealing material 4 is in close contact with the outer periphery of each tube body 2, 2.
この従来の管継手によると次の欠点がある。 This conventional pipe joint has the following drawbacks.
イ 環状シール材４とロツクリング３は、それぞ
れ筒体１の内周に切削形成した環状溝７，８に
嵌合する構造である。このため、各環状溝７，
８に環状シール材４とロツクリング３を嵌合す
る作業が面倒である。(a) The annular sealing material 4 and the lock ring 3 are structured to fit into annular grooves 7 and 8 cut into the inner periphery of the cylindrical body 1, respectively. For this reason, each annular groove 7,
The work of fitting the annular seal member 4 and the lock ring 3 to the ring 8 is troublesome.
ロ また、環状シー材４は、筒体１に管体２を挿
入する前に予め環状溝７に嵌合しておかなけれ
ばならないが、図からも容易に推測されるよう
に、筒体１に管体２を挿入する際、その先端９
が環状シール材４に引掛り、環状溝７から外れ
るおそれがある。(b) Furthermore, the annular sheet material 4 must be fitted into the annular groove 7 in advance before inserting the tube 2 into the tube 1; When inserting the tube body 2 into the
There is a risk that the annular seal material 4 may get caught and come off from the annular groove 7.
しかも、環状シール材４の内面を傷にし、シ
ール性の低下を来すおそれがある。 Furthermore, there is a risk that the inner surface of the annular sealing material 4 may be damaged, resulting in a decrease in sealing performance.
ハ 突部６は、その周長方向と直角の断面がほぼ
方形であるが、このような断面形状の突部６で
あると、管体２への溶接時、その軸線との直角

るおそれがあり、正しく溶接するためには、専
用の治具が必要となつて、現場作業性、品質保
証上の問題が残る。C. The protrusion 6 has a substantially rectangular cross section perpendicular to its circumferential direction, but if the protrusion 6 has such a cross-sectional shape, it will be difficult to accurately align the right angle to its axis when welding it to the pipe body 2. It is difficult to remove the weld, there is a risk of welding at an angle, and special jigs are required to weld correctly, which poses problems in field workability and quality assurance.
ニ 管体２は筒体１に対し曲げモーメントを受け
るが、この場合、１つの支点（つまり突部６と
筒体１の内周接触面）で可撓性を持たせてい
る。D. The tubular body 2 receives a bending moment with respect to the tubular body 1, but in this case, it is made flexible at one fulcrum (that is, the inner peripheral contact surface of the protrusion 6 and the tubular body 1).
このため、管体２が曲がつた際、環状シール
材４と管体２の外周との隙間は、周長方向に狭
い部分と広い部分が発生し、シールの効きが不
確実なものとなるおそれがある。 Therefore, when the tube body 2 is bent, the gap between the annular sealing material 4 and the outer periphery of the tube body 2 will have narrow parts and wide parts in the circumferential direction, making the effectiveness of the seal uncertain. There is a risk.
ホ 工場での継手製作上の問題点として、２つの
環状溝７，８の溝切り工程が挙げられる。特に
環状シール材４を嵌合する環状溝７は、筒体１

イトで切削しなければならず、作業が困難であ
る。E. One of the problems in manufacturing the joint at the factory is the process of cutting the two annular grooves 7 and 8. In particular, the annular groove 7 into which the annular sealing material 4 is fitted is formed on the cylindrical body 1.
Because it is located further back than the end of the blade, it must be cut with a long cutting tool, making the work difficult.
