Abstract
Official abstract text for this publication.
A electrical wire protection tube and a wire harness that can prevent breakage of a wire arranged in the handle swing portion of a two-wheeled vehicle. The electrical wire protection tube includes a tube main body portion made up of ring-shaped ribs and small-diameter short tube portions that are a resin molded body and are alternatingly arranged in a single line so as to form one passageway for an electrical wire. Each ring-shaped ribs has a maximum-diameter ridgeline portion and first and second truncated cone surface portions that are respectively located on different sides of the ridgeline portion and are inclined toward the small-diameter short tube portions. When the tube main body portion is bent into a U shape, the small-diameter short tube portions stretch on one side such that the first and second truncated cone surface portions of adjacent ring-shaped ribs come into close contact on the opposite side.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electrical wire protection tube comprising: a tube main body portion that is made up of ring-shaped ribs and small-diameter short tube portions that are a resin molded body and are alternatingly arranged in a single line so as to form one passageway for passage of an electrical wire, holes of the ring-shaped ribs and holes of the small-diameter short tube portions having the same diameter, wherein in each of the ring-shaped ribs, a diameter corresponding to a central portion in an axial direction is a maximum diameter, each of the ring-shaped ribs has a maximum-diameter ridgeline portion and inclined surfaces that are respectively located on one side and another side of the ridgeline portion and are inclined toward the small-diameter short tube portions, and when the tube main body portion is bent into a U shape, the small-diameter short tube portions stretch on one side of the tube main body portion and the inclined surfaces of the adjacent ring-shaped ribs become in close contact with each other on an opposite side of the tube main body portion such that three to eight of the ring-shaped ribs that are adjacent to each other are located in a 180-degree bending range. 2. A wire harness comprising: an electrical wire; and the electrical wire protection tube according to claim 1 , wherein the electrical wire is inserted into the passageway of the tube main body portion.
