<p><P>PROBLEM TO BE SOLVED: To provide a corrugated tube allowing a wire harness to bend easily in one direction while making it difficult for the wire harness to bend in another direction perpendicular to the one direction, which corrugated tube makes it more difficult for the wire harness to bend in another direction. <P>SOLUTION: Corrugated tubes 1, 11 and 11' have peripherally directed grooves 2 and projecting stripes 3 arranged alternately in the tube's longitudinal direction, and reinforcing ribs 4, 12 and 12' that extend in the tube's longitudinal direction from the outer peripheral surfaces 2a of the grooves 2 to project out of the peripheral surfaces 3a of the projecting stripes. The inside of the ribs 1 and 12' are partially or entirely made into hollows 5 and 14, while the inside of the rib 12 is made into a substance 12c. Corrugated tubes 21 and 21' have peripherally directed grooves 2 and projecting stripes 3 arranged alternately in the tube's longitudinal direction, and reinforcing ribs 22 and 22' formed in the tube's longitudinal direction. The inside of the ribs are partially or entirely made into solid substances 22c and 22c'. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
