Patent ID: 8119913

Claim:
A protector for a wire harness comprising: a first protector member made of a resin molding product and having a U-shaped configuration in cross section that includes a bottom wall and parallel opposed side walls, said first protector member being provided on a longitudinal end with a first coupling portion; and a second protector member made of a resin molding product and having a U-shaped configuration in cross section that includes a bottom wall and parallel opposed side walls, said second protector member being provided on a longitudinal end with a second coupling portion; said first and second coupling portions being connected to each other; said first coupling portion of said first protector member including an inner wall section having a U-shaped cross section and a cover section, said inner wall section having an inner bottom wall and parallel opposed inner side walls that are continuously connected to said parallel opposed side walls of said first protector member, and said cover section extending from an outer surface of said inner bottom wall through opposite corners to said opposed inner side walls of said inner wall section to define a double wall structure, said cover section projecting to a distal end opening in said first protector member, said double wall structure being open at a coupling end, said inner bottom wall or said opposed inner side walls of said inner wall section being provided with a through-hole, and a clearance being defined between said inner wall section and said cover section; said second coupling portion of said second protector member including a bottom wall and opposed side walls that are inserted through said distal end opening into said clearance in said first coupling portion, said opposed side walls of said second coupling portion being continuously connected to said opposed side walls of said second protector member, said bottom wall of said second coupling portion being disposed at a lower position than said bottom wall of said second protector member, and said second coupling portion being provided on said bottom wall of said second coupling portion or opposed side walls of said second coupling portion with a protrusion to be fitted in said through-hole in said inner wall section; said first and second coupling portions of said first and second protector members being adapted to define a triple wall structure in which said second coupling portion of said second protector member is caught between said inner wall section of said first coupling portion and said cover section of said first coupling portion having said double wall structure, and said bottom walls of said first and second protector members being continuously connected to each other without causing a stepped portion.
