<P>PROBLEM TO BE SOLVED: To prevent a slit from being opened even when a corrugated tube is warped. <P>SOLUTION: A corrugated tube is made of a resin molded product externally mounted on an electric wire group. The corrugated tube includes: annular crest parts and annular valley parts disposed alternately in an axial direction; and a slit extended over the entire length in the axial direction. Engagement parts extended in the axial direction along both edges with the slit interposed therebetween are disposed at a required width in a circumferential direction, and circumferential notches are respectively provided from the edges in the valley parts located at the engagement parts so as to allow the crest parts on both sides to be independently bendable. On the other hand, the crest parts located at the engagement parts include: protrusions that are protruded on top faces of the crest parts on one of both sides with the slit interposed therebetween; and recesses disposed in the crest parts on the other side opposite the crest parts provided with the protrusions. The recesses are configured to internally engage the protrusions, and are openedly provided in lower surfaces of the crest parts. The protrusions and recesses are disposed alternately in the crest parts adjacent to each other in the axial direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
