PROBLEM TO BE SOLVED: To provide a wire protective tube capable of preventing a wire and the like to step out, cabling the wire in a narrow space of a vehicle and improving the workability of wire insertion. SOLUTION: A plurality of elastic parts 20 extending over the overall length in the axial direction are formed at a wall 12 of a box 11 so as to enable the box 11 to expand in the radius direction. The elastic parts 20 are symmetrically disposed relative to the axial core of the box 11 of which the cross section is formed into a flat or oblong shape. The elastic parts 20 are located at centers of a major axis 18 and a minor axis 19 of the box 11. The wall 18 and the elastic parts 20 are simultaneously integrally formed by two-color forming, so that they are not peeled off from a border section 22. The wall 12 is made of polypropylene or polyethylene or polyamide or polyethylene terephthalate of Rockwell hardness of R60 to 100, and the elastic part 20 is made of an ethylene-vinyl acetate copolymer or ethylene-propylene rubber or thermoplastic elastomer of Shore hardness of A50 to 90. |
