PROBLEM TO BE SOLVED: To provide a corrugated tube capable of specifying the bending position and direction.SOLUTION: A corrugated tube 1 includes a bellows structure having normal portions 11 formed by arranging a plurality of projecting bars 5 having a constant width in the circumferential direction and recessed grooves 6 between the projecting bars 5 in parallel in a peripheral wall part 4 at an equal interval pitch in the longitudinal direction. A pitch between one projecting bar 5A and the recessed groove 6 in the cross sectional direction and a pitch between the other projecting bar 5A and the recessed groove 6 are different from each other. A bending specified portion 12 formed so that the pitch between the other projecting bar 5A and the recessed groove 6 in the cross sectional direction becomes smaller than that of the normal portions 11 is provided between the normal portions 11 or adjacently to the normal portions 11. |
