端部３１の外径を他の管体４の端部４１の内径よ
り僅かに小さく形成し、前者３１（以下『内管』
という。）を後者４１（以下『外管』という。）
の内部に入れ子式に挿入可能なよう構成すると共
に、上記外管４１の管壁を所定の間隔を隔てた軸
方向の平行線に沿つて所望の長さだけ切断し、当
該平行線の間の領域を外管の内部へ突出するよう
押し込んで湾曲したバネ部４２を形成し、外管４
１内へ上記内管３１を挿入したとき上記バネ部４
２の内面が内管３１の外周面に圧接するよう構成
したことを特徴とする入れ子式管継手。 The outer diameter of the end 31 of one of the two tubes 3 and 4 to be connected is formed to be slightly smaller than the inner diameter of the end 41 of the other tube 4, and the former 31 (hereinafter referred to as ``inner tube'') ”
That's what it means. ) is the latter 41 (hereinafter referred to as the "outer tube").
In addition, the tube wall of the outer tube 41 is cut to a desired length along parallel lines in the axial direction separated by a predetermined interval, and a section between the parallel lines is cut. The curved spring portion 42 is formed by pushing the region into the outer tube so as to protrude into the outer tube 4.
When the inner tube 31 is inserted into the spring portion 4
1. A telescoping pipe joint characterized in that the inner surface of the tube 2 is in pressure contact with the outer circumferential surface of the inner tube 31.
