<P>PROBLEM TO BE SOLVED: To provide a more lightweight corrugated tube, and a method for manufacturing the corrugated tube. <P>SOLUTION: The method for manufacturing the corrugated tube includes; (a) a step of forming a cylindrical member which has an annular large diameter part 12 and a small diameter part 18 which alternately continue in one direction, and a hollow protrusion 16 of the hollow shape which projects to an outer peripheral side from an outer peripheral surface of the large diameter part 12; and (b) a step of cutting off the hollow protrusion 16 from the cylindrical member. In the corrugated tube, the annular large diameter parts and small diameter parts alternately continue in an extending direction and are formed in the cylindrical shape and the hole penetrated in the direction of inside and outside is formed in the outer periphery of the large diameter part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
