Is slightly (θ 1 ) or largely (θ 2 ) tilted, the central axis of the pipe passes near the central axis 3a of the ring receiving groove 3 and is tilted. Therefore, when the pipe is bent, the outlet 5 of the pipe 1A
The end surface 5a does not exert a particular external force on the tube end receiving surface 4, and damage to the tube 1A and the receiving portion 2 can be suppressed and prevented. Further, even if the pipe 1A is slightly (θ 1 ) or greatly (θ 2 ) tilted from the receiving portion 2 due to a load acting in the axial direction due to a change in earth pressure, the inlet 5 of the pipe 1A receives the pipe end receiving. Since it abuts on the surface 4 in a wide range 5d (see the dotted line in FIG. 4 and the dotted line and arrow area in FIG. 6), the load can be transmitted to the pipe end receiving surface 4 in a dispersed state, and the pipe 1A and the receiving end can be transmitted therethrough. It is possible to suppress and prevent damage to the mouth 2. Further, if the spigot 5 of the pipe 1A is curved on the spherical surface S and the lubricant is applied to the pipe end receiving surface 4 and the lubricating groove 7 respectively, the pipe end receiving face 4 will not be affected even when a load is applied in the axial direction. A wide contact area can be obtained on the surface 4, and a large frictional force is not generated. Therefore, since the pipe 1A rotates smoothly, it can be expected that the damage to the pipes 1 · 1A and the receiving portion 2 can be reliably suppressed and prevented. Furthermore, tube 1.1A
Since it is injection-molded using synthetic resin as a material, it is possible to cope with complicated shapes very easily, and furthermore, electrical insulation, chemical resistance, weather resistance, adhesiveness, weldability, weight reduction,
Further, it is possible to significantly improve rigidity and the like.

う顕著な効果がある。As described above, according to the present invention, a spherical surface is assumed around an arbitrary point of the central axis of the seal receiving portion, and the pipe end receiving surface is formed so as to be a part of this spherical surface. As a result, there is a special effect that it is possible to prevent and prevent damage to the pipe and the receiving portion due to the bending of the pipe path and the like. Further, according to the invention described in claim 2, since the end portion of the other pipe member is formed into a spherical surface, a wide contact area can be obtained on the pipe end receiving surface even when an external force acts in the axial direction, and the pipe member Rotates smoothly,
Through this, it becomes possible to suppress and prevent damage to the pipe member and the receiving portion. Further, according to the invention described in claim 3,
Since the lubricant is applied to the pipe end receiving surface and the lubrication groove, even if an external force acts in the axial direction, the pipe member will rotate smoothly, and it can be expected to prevent damage to the pipe member and the receiving part. It has a great effect.
