ABSTRACT:
An electric wire 10 is provided with a shielding layer 12 inside an outer sheath 11, three insulated wires 13 being provided therein. A correcting ring 46 is inserted between the outer sheath 11 and the shielding layer 12 of the electric wire 10, correcting the outer sheath 11 into a circular shape. A waterproofing ring 39 is attached tightly to an outer peripheral face of the outer sheath 11. In this way, even in the case where the shape of the outer sheath 11 of the electric wire 10 provided with a plurality of insulated wire cores 13 tends to be unstable, the electric wire 10 can be maintained in a specified shape by the correcting ring 46. Consequently the waterproofing ring 39 can fit stably and tightly to the outer peripheral face of the electric wire 10, thereby improving the waterproofing function.
