<p><P>PROBLEM TO BE SOLVED: To provide a metal bellows tube greatly improving bending fatigue resistance than that of a conventional one. <P>SOLUTION: The cross section of crests 2 and troughs 3 in a bellows tube wall 1 of the metal bellows tube 10 has a V shape. The pitch of the bellows is preferable to be 1.5mm or less and the height of the crest is preferable to be 0.5-4.0mm. This metal bellow tube is especially suited to a flexible tube and materializes the flexible tube with superior durability. <P>COPYRIGHT: (C)2004,JPO</p> |
