<p>PROBLEM TO BE SOLVED: To provide a protection tube enabling easy cable protection work for protecting an electric wire of a wire harness.SOLUTION: A protection tube 11 for protecting an electric wire 15 of a wire harness 13 includes a small-diameter protection tube 35 and a large-diameter protection tube 37 coated on the small-diameter protection tube 35 in a relatively movable manner. The small-diameter protection tube 35 and the large-diameter protection tube 37 relatively moved in a longitudinal direction are mutually engaged with friction by that the shape of a cross section orthogonal to a tube axial line of at least one of the small-diameter protection tube 35 and the large-diameter protection tube 37 is formed to have a non-circular shape with a predetermined pressing deformation or larger from a circular cross section.</p> |
