  • Patent number: 8624114
    Abstract: A buffering part 34 is formed by turning an end side of a wiring harness 30 in a U-shape, and by detachably holding a neighbor of an end of the wiring harness 32 with a retainer 29 of a protector 24 disposed on a middle of the wiring harness 33. A circular portion of the buffering part 34 can work as a buffer. The buffer performance of the buffering part 34 depends on flexibility and resiliency of a corrugate tube 25 and on a circular shape formed between a holding position of the retainer 29 and the neighbor of the end of the wiring harness 32.

    Abstract: This invention is to provide a protector capable of discharging water into an outside and a wire harness including the protector. A drainage hole is formed as a portion so as to discharge water collecting in an electrical wire receiving portion into an outside. The drainage hole is formed so as to penetrate through the electrical wire receiving portion and toward the rear of a vehicle. Further, the drainage hole is formed so as to gradually slope from the electrical wire receiving portion toward the ground surface. The drainage hole is a through hole which is formed at a position near an end portion of a protection member for the vehicle interior. The drainage hole is formed and located in a portion of the wire harness which is the closest to the ground surface.
