ことができる。As described above, in the jig for mounting a corrugated tube according to the present invention, the jig body is inserted into the corrugated tube with its slit portion expanded with the bottom thereof facing down, and both sides of the jig body are inserted. The wall supports each slit edge on both sides of the corrugated tube slit to maintain the expanded state, and drops the wire harness to the bottom from the top between both side walls of the jig body, and cures in this state. The jig body is moved relatively to the corrugated tube, and the corrugated tube is wrapped around the wire harness at the back of the jig body in the relative traveling direction. The jig body has a relatively short length, a small frictional resistance, and can be mounted with a corrugated tube on a wire harness with good workability. One of the side walls has a rear portion in the direction in which the jig body advances relative to the corrugated tube, and one of the slit edges of the corrugated tube supported by the one side wall. Since the notch is provided so as not to support the part, when used for mounting the overlap type corrugated tube,
The corrugated tube can be attached to the wire harness such that the direction of the overlap portion is always constant.
