<p><P>PROBLEM TO BE SOLVED: To enable to obtain a pipe used for vibration proof with low cost. <P>SOLUTION: Joints 12, 13 with the other equipment are installed at both ends of a flexible tube 11 formed by a wavelike corrugated pipe 14. A top end of the wavelike corrugated pipe 14 is inserted in the joints 12, 13. The joints 12, 13 and the wavelike corrugated pipe 14 are mutually rotatably formed around the center of axis. The joints 12, 13 have sealing subatances 25, 26 capalbe of sealing the outer periphery of the wavelike corrugated tube 14 and a retainer 31 capable of preventing from being slipped off from the joints 12, 13 for the wavelike corrugated pipe 14 engaging with the wavelike corrugated pipe 14. In the wavelike corrugated pipe 14, the pitch of the wave in the portion 19 at least between each joint 12, 13 is formed smaller compared with the pitch of the wave in an inserting portion 18 to the inside of the joints 12, 13. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
