Abstract

Official abstract text for this publication.

A wire harness includes: an electric wire; a plate spring member; a sheath member; and a protector that integrally holds an end part of the sheath member and portions of the electric wire and the plate spring member led out from the end part of the sheath member. The protector includes: a protector main body having a routing space part where the electric wire, the plate spring member, and the sheath member are routed; and a lid part that closes the routing space part. The routing space part is provided with: a pair of regulation parts that supports both ends of the routed plate spring member, and regulates a height position of the plate spring member in the protector with respect to a height direction; and a housing recessed part that is located between the pair of regulation parts and houses an excess portion of the sheath member.

First claim

Opening claim text (preview).

The invention claimed is: 1 . A wire harness comprising: an electric wire exhibiting flexibility; an elastic plate spring member that extends along the electric wire and restricts a path of the electric wire; a sheath member exhibiting flexibility into which the electric wire and the plate spring member are inserted; and a holding member that integrally holds an end part of the sheath member and portions of the electric wire and the plate spring member led out from the end part of the sheath member, wherein the holding member comprises; a main body that includes a routing space part where the electric wire, the plate spring member, and the sheath member are routed along an axial direction; and a lid part that is attached to the main body and closes the routing space part, and the routing space parts provided with; a pair of regulation parts that supports both ends of the routed plate spring member in a width direction via the sheath member, the pair of regulation parts regulating a height position of the plate spring member in the holding member with respect to a height direction that intersects with the axial direction; and a housing recessed part that is located between the pair of regulation parts, and houses an excess portion of the sheath member in a circumferential direction. 2 . The wire harness according to claim 1 , wherein the plate spring member is curved on an outer side of the holding member, and supported by the regulation parts by being pressed against the regulation parts by an energizing force of the plate spring member via the sheath member. 3 . The wire harness according to claim 1 , wherein the holding member includes a plurality of protrusions protruding from the lid part toward the main body, the protrusions locking the sheath member on an opposite side of the regulation parts with respect to the height direction. 4 . The wire harness according to claim 2 , wherein the holding member includes a plurality of protrusions protruding from the lid part toward the main body, the protrusions locking the sheath member on an opposite side of the regulation parts with respect to the height direction. 5 . The wire harness according to claim 1 , wherein the sheath member is formed by weaving insulating fibers into a tubular shape. 6 . The wire harness according to claim 2 , wherein the sheath member is formed by weaving insulating fibers into a tubular shape. 7 . The wire harness according to claim 3 , wherein the sheath member is formed by weaving insulating fibers into a tubular shape.
