There is provided a wire harness structure which prevents an extraordinary displacement of a wire harness, and immediately discharges water from the wire harness when the water such as rain water splashes on the wire harness so that the freezing of the residing water and undesirable cutting of wires due to the freezing can be prevented. At an extending portionof the wire harness, a strip-like plate springand the wiresare integrally combined together, and are covered with a mesh-like protective memberso that water will not reside therein. Even when water such as rain water splashes on the extending portion, the water is discharged through mesh holes of the protective member, and will not reside in the extending portion. Therefore, the freezing of the residing water can be prevented, and the cutting of the wirescan be prevented from occurring.

Wire harness installation structure

A wiring structure of electric wire is provided in which the efficiency of wiring electric wires can be improved and the wiring space can be saved. The wiring structure of electric wire includes an electric wire having a U-shaped excessive part provided in its middle part along the relatively-moving direction of two structures, and a longitudinally-appended spring member provided longitudinally along the electric wire. Fixing positions Pand Pof opposite ends of the electric wire are set to offset positions which are deviated in position respectively in two directions perpendicular to the relatively-moving direction of the two structures, and an elastic rod member which has a circular or regular polygonal cross section, having a property of non-biased bending in direction, is used as the longitudinally-appended spring member.

A wire harness assembly includes an electric wire including: a fixed-side connecting portion to be fixed to a fixed structure; a movable-side connecting portion to be fixed to a movable structure which is movable with respect to the fixed structure; and an extension portion extended and flexed from the fixed-side connecting portion to the movable-side connecting portion in a substantially U-shape or arc shape, and having an extra length for allowing the movement of the movable structure. The wire harness assembly also includes an elastic rod member which is provided along the extension portion of the electric wire.

A purpose of the invention is to improve a bending durability of a slip-like plate spring arranged along a wire harness by preventing the slip-like plate spring from being corroded, and to provide a wire harness installation structure in which a conductor in electric wires is not liable to be broken. The wire harness installation structure includes the electric wiresthat have one ends electrically connected to an electric component provided on a stationary-side structural body and the other ends electrically connected to an electric component provided on a movable-side structural body, the slip-like plate springthat is made of metal and has one end fixed to the stationary-side structural body and the other end fixed to the movable-side structural body, and a binding memberthat is adapted to bind the electric wiresto the slip-like plate spring. In the wire harness installation structure, the electric wiresare bound by the binding memberto the slip-like plate springat a portion other than a portion of the slip-like plate springto which an extremely large load is applied when the slip-type plate springis bent and deformed in accordance with the movement of the movable structural body.
