PROBLEM TO BE SOLVED: To provide a sheath protection tube for an electric wire in which rigidity of a non-bendable straight tube part is improved uniformly in a circumferential direction and a length direction and a fixture member can be easily fixed.SOLUTION: A sheath protection tube 1 for an electric wire is formed by alternately concatenating a freely bendable part 10 and a non-bendable straight tube part 20 and fixed at a predetermined mounting position by a fixture member 50. The non-bendable straight tube part 20 in at least one section includes: lengthwise movement regulating protrusions 30 which are provided protrusively on an outer circumferential surface 20a of the non-bendable straight tube part 20 along the circumferential direction of the non-bendable straight tube part 20 and provided continuously along the length direction of the non-bendable straight tube part 20 at intervals equal to a width of the fixture member 50 in such a manner that the fixture member 50 is fixedly disposed therebetween; and circumferential movement regulating protrusions 40 which are provided protrusively on the outer circumferential surface 20a of the non-bendable straight tube part 20 so as to linearly extend from one end of the non-bendable straight tube part 20 to the other end along the length direction of the non-bendable straight tube part 20 in order to regulate circumferential movement of the fixture member 50 with respect to the non-bendable straight tube part 20. |
