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.

Electric wire protecting pipe and wire harness

A wire harness and an electric wire protecting pipe that can prevent holes from being formed by flying gravel while the vehicle is moving and includes a bending pipe portion that can be bent easily. The electric wire protecting pipe is a resin pipe into which electric wires are insertable, and includes 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. A thickness of a lower wall portion that is disposed on a lower side when the electric wire protecting pipe is attached to a vehicle is greater than a thickness of a left wall portion and a right wall portion.

A shield conductive path may include a tubular shield portion that surrounds a plurality of electric wires. The shield conductive path may further include a partition portion that partitions an interior space of the shield portion into a plurality of electrical wire insertion paths. A specific electrical wire may be inserted through a specific electrical wire insertion path of the plurality of electrical wire insertion paths and may be guided out from a guiding-out opening formed in the shield portion, to the outside of the shield portion, and this guiding-out opening can be formed within an area, of the shield portion, provided with the partition portion.

Shield conductive path

A shielded conductive path that can facilitate manufacturing operations is provided. A shielded conductive path includes a shielding pipe that is configured to have a tubular shape into which an electric wire can be inserted, by combining together a pair of divided bodies into which the shielding pipe is divided along its axis, and an overlapping fitting portion that is provided at a joint portion of the pair of divided bodies and allows the pair of divided bodies to be fitted to each other while overlapping each other in an inside-outside direction when the pair of divided bodies are combined together. Thus, the operations for manufacturing the shielded conductive path can be performed easily.
