Abstract

A wire harness and an electric wire protecting pipe that can protect electric wires without including a separate component for shielding a drain hole. The electric wire protecting pipe is a resin pipe into which electric wires are insertable, and a lower wall portion is provided integrally with a projecting portion that projects outward, and a circumferential wall portion of the projecting portion is provided with a drain hole. According to such a configuration, the electric wires are protected from flying gravel, splashing water, or the like, by the projecting portion that is formed integrally with the electric wire protecting pipe, and thus the electric wires can be protected without including a separate component for shielding the drain hole.

First claim

The invention claimed is:

1. An electric wire protecting pipe that is a resin pipe into which electric wires are insertable, comprising:
a lower wall portion is disposed on a lower side when the electric wire protecting pipe is attached to a vehicle, the lower wall portion includes an opening,
a drain portion integrally formed in the lower wall portion by blow molding or vacuum molding such that the drain portion extends from and is made from the same resin material as the lower wall portion, the drain portion includes a projecting portion,
the projecting portion projects outward from the lower wall portion such that it covers the opening in the lower wall portion, the projecting portion includes a circumferential wall portion, and
the circumferential wall portion is provided with a drain hole that is open in a direction intersecting a direction from the inside to the outside of the electric wire protecting pipe.

2. The electric wire protecting pipe according to claim 1 , wherein the drain hole is formed in a wall portion of the circumferential wall portion of the projecting portion that is disposed on a rear side when the electric wire protecting pipe is attached to the vehicle.

3. The electric wire protecting pipe according to claim 1 , comprising:
a bending pipe portion that is easily bent and is provided with protruding portions and recessed portions that are alternately continuous with each other in an axial direction; and
a straight pipe portion that is flat and is not easily bent in the axial direction.

4. The electric wire protecting pipe according to claim 1 , whose cross section that is approximately orthogonal to the axial direction has a flat shape.

5. The electric wire protecting pipe according to claim 1 , wherein a lower wall of the projecting portion is inclined downward toward the drain hole.

6. The electric wire protecting pipe according to claim 1 , comprising:
a bending pipe portion that is easily bent and is provided with protruding portions and recessed portions that are alternately continuous with each other in an axial direction; and
a straight pipe portion that is flat and is not easily bent in the axial direction,
wherein a thickness of the lower wall portion is greater than a thickness of a left wall portion and a right wall portion that are disposed on left and right sides.

7. A wire harness in which a plurality of electric wires are inserted into the electric wire protecting pipe according to claim 1 .
