いる。(Prior Art) Conventionally, as a connection structure of this type of ribbed pipe, for example, one disclosed in Japanese Utility Model Laid-Open No. 62-68086 is known.

た。In this connection structure, as shown in FIG. 4, a seal ring d is fitted between the ribs c at the ends of the insertion portion b of the ribbed pipe a, and in this state, the receiving portion of another ribbed pipe a. It is fitted in e to secure the sealing property between the receiving part e and the insertion part b. Further, in this case, it is easy to fit the seal ring d between the ribs c at the end of the insertion portion b from the viewpoint of workability, and also from the viewpoint of increasing the effective length of the ribbed pipe a. It was advantageous.
（考案が解決しようとする課題） しかしながら、上記従来の接続構造にあっては次のよう

端部のリブｃ間にシールリングｄを嵌着した場合、水密
性を確保するのが困難になるといった不都合を生じる。That is, in such a connection structure, since the insertion part b is fitted into the receiving part e via the seal ring d, the outer diameter of the inserting part b is smaller than the inner diameter of the receiving part e. Must be slightly smaller. Further, the receiving portion e of the ribbed pipe a is
Since the dimensional accuracy in molding is poor,
When inserting the insertion part b of the other ribbed tube a, the insertion part b will be somewhat loose in the receiving part e. That is, the stress concentration due to this rattling becomes greater toward the inner end or the outer end of the receiving port e. Therefore, when the seal ring d is fitted between the ribs c at the end of the insertion part b, the seal ring d is not compressed evenly, resulting in inconvenience that the watertightness is not stable. In addition, the end portion of the insertion portion b of the ribbed tube a may be damaged during transportation work or the like, and a seal ring is formed between the ribs c at the end portion of the insertion portion b thus damaged. When d is fitted, it is difficult to ensure water tightness.

題がある。Furthermore, at the time of connecting the ribbed pipe a, when inserting the insertion part b into the receiving part e, a so-called centering work is performed.
If the seal ring d is fitted between the ribs c at the end of the insertion portion b, there is a problem that the centering operation of the seal ring d becomes very difficult.

易となる。(Operation) A seal ring is fitted between the second rib from the end of the insertion portion of the ribbed tube, and this insertion portion is fitted into the receiving portion of another ribbed tube. At this time, the seal ring is located closer to the central portion of the receiving portion, is less susceptible to stress concentration due to rattling between the receiving portion and the insertion portion, and biases compression of the sealing ring. Disappear. Further, since the tube end portion without the seal ring at the tip of the insertion portion plays a role of a guide when the insertion portion is inserted into the receiving portion, the centering work becomes easy.
（実施例） 以下、本考案の実施例を図面を参照して説明する。Embodiment An embodiment of the present invention will be described below with reference to the drawings.
第１図は、本考案に係るリブ付管の接続構造を示してい

た、受口部２の長さＬは、リブ付管１、１同士の接合強
度及び可撓性を保つのに充分な寸法となされている。The inner diameter of the receiving port 2 is increased to be substantially the same as the outer circumference of the ribbed pipe 1, so that the ribbed pipe 1 can be inserted. Further, the length L of the receiving portion 2 is set to a size sufficient to maintain the joint strength and flexibility of the ribbed tubes 1, 1 with each other.
挿入部３は、本実施例の場合、受口部２を拡径している
ので、リブ付管１の管端がそのままの状態で挿入部３と
なされている。In the case of the present embodiment, since the insertion portion 3 expands the diameter of the receiving portion 2, the insertion portion 3 is formed with the tube end of the ribbed tube 1 as it is.

グ４は、部分的に肉ぬきされて弾性力を増すようになさ
れていることが好ましい。The seal ring 4 is made of a material such as rubber having elasticity and is formed in an annular shape substantially equal to the outer diameter of the ribbed tube 1. Further, the seal ring 4 is formed with a substantially equal width between the ribs 11 of the ribbed tube 1, and is made higher than the height of the ribs 11 when fitted between the ribs 11. It is preferable that the seal ring 4 is partially hollowed to increase the elastic force.

じなくなる。Then, the seal ring 4 is fitted between the second ribs 11 from the end of the insertion portion 3 of the ribbed tube 1, and the insertion portion 3
The ribbed pipes 1 and 1 are connected to each other by fitting the above into the receiving portion 2 of the other ribbed pipe 1. As a result, the seal ring 4 comes closer to the central portion of the receiving portion 2, and is less susceptible to stress concentration due to rattling between the receiving portion 2 and the insertion portion 3, and the seal ring 4 is compressed. Bias will not occur.
