WIRE HARNESS PROTECTION STRUCTURE

摘要

A wire harness protection structure includes a bundle of electric wires, and a protector formed into a tubular body that extends in a longitudinal direction of the bundle of electric wires and having a portion of the bundle of electric wires provided in an inner space of the tubular body. The protector is formed of a protection material including a base material and a binder material having a melting point lower than that of the base material. A joint portion of the protector is joined by heating and melting and then cooling and solidifying the binder material. The binder material in an inner peripheral surface is heated and melted and then cooled and solidified such that the inner peripheral surface, which faces the inner space, is harder than an outer peripheral surface of the protector.
