Abstract

A wire harness includes an electric wire, an exterior member, and a protector integrally holding an end portion of the exterior member and a portion of the electric wire led out from the end portion of the exterior member. The protector includes a protector main body having a routing space portion in which the electric wire and the exterior member are routed along an axial direction, a lid portion attached to the protector main body to close the routing space portion, and a plurality of first protrusions and second protrusions protruding from the lid portion toward the protector main body and locking the exterior member, and height positions of distal ends of the plurality of first protrusions and second protrusions varies according to a formation position.

Claims (51)

1. A wire harness comprising:

an electric wire having flexibility;

an exterior member through which the electric wire is inserted, the exterior member having flexibility; and

a holding member integrally holding an end portion of the exterior member and a portion of the electric wire led out from the end portion of the exterior member, wherein

the holding member includes

a main body having a routing space portion in which the electric wire and the exterior member are routed along an axial direction of the wire harness,

a lid portion attached to the main body to close the routing space portion, and

a plurality of protrusions protruding from only one of the main body and the lid portion toward the other of the main body and the lid portion, extending into and locking the exterior member through which the electric wire is inserted, and

a height position of a distal end of the plurality of protrusions with respect to a height direction intersecting the axial direction varies according to a formation of the plurality of protrusions relative to a width direction intersecting the axial direction and the height direction.

2. The wire harness according to claim 1 , further comprising:

a leaf spring member extending along the electric wire, regulating a path of the electric wire, having elasticity, and being inserted into the exterior member together with the electric wire, wherein

the main body includes a pair of regulation portions that supports both ends in a width direction of the leaf spring member routed in the routing space portion via the exterior member and regulates a height position of the leaf spring member in the holding member with respect to the height direction intersecting the axial direction, and

the height position of the distal end of the plurality of protrusions with respect to the leaf spring member supported by the pair of regulation portions varies according to the formation of the plurality of protrusions.

3. The wire harness according to claim 1 , wherein

the exterior member is formed by knitting insulating fibers into a tubular shape.

4. The wire harness according to claim 2 , wherein

the exterior member is formed by knitting insulating fibers into a tubular shape.

5. A wire harness comprising:

an electric wire having flexibility;

an exterior member through which the electric wire is inserted, the exterior member having flexibility;

a holding member integrally holding an end portion of the exterior member and a portion of the electric wire led out from the end portion of the exterior member; and

a leaf spring member extending along the electric wire, regulating a path of the electric wire, having elasticity, and being inserted into the exterior member together with the electric wire, wherein

the holding member includes

a main body having a routing space portion in which the electric wire and the exterior member are routed along an axial direction of the wire harness,

a lid portion attached to the main body to close the routing space portion, and

a plurality of protrusions protruding from one of the main body and the lid portion toward the other of the main body and the lid portion and locking the exterior member,

a height position of a distal end of the plurality of protrusions with respect to a height direction intersecting the axial direction varies according to a formation of the plurality of protrusions,

the main body includes a pair of regulation portions that supports both ends in a width direction of the leaf spring member routed in the routing space portion via the exterior member and regulates a height position of the leaf spring member in the holding member with respect to the height direction intersecting the axial direction, the height position of the distal end of the plurality of protrusions with respect to the leaf spring member supported by the pair of regulation portions varies according to the formation of the plurality of protrusions, and

the height position of the distal end of one of the plurality of protrusions on an inner side in a width direction of the holding member with respect to the leaf spring member supported by one of the pair of regulation portions via the exterior member is higher than the height position of the distal end of another of the plurality of protrusions on an outer side in the width direction.

6. The wire harness according to claim 5 , wherein

the exterior member has a configuration in which an adhesive tape is wound around a part housed on an inner side of the holding member, and

among the plurality of protrusions, a protrusion corresponding to a region where the adhesive tape is disposed in an axial direction of the holding member is higher in height position of the distal end with respect to the leaf spring member supported by one of the pair of regulation portions via the exterior member than another protrusion corresponding to a region where the adhesive tape is not disposed.

7. The wire harness according to claim 6 , wherein

the exterior member is formed by knitting insulating fibers into a tubular shape.

8. The wire harness according to claim 5 , wherein

the exterior member is formed by knitting insulating fibers into a tubular shape.

9. A wire harness comprising:

an electric wire having flexibility;

an exterior member through which the electric wire is inserted, the exterior member having flexibility;

a holding member integrally holding an end portion of the exterior member and a portion of the electric wire led out from the end portion of the exterior member; and

a leaf spring member extending along the electric wire, regulating a path of the electric wire, having elasticity, and being inserted into the exterior member together with the electric wire, wherein

the holding member includes

a main body having a routing space portion in which the electric wire and the exterior member are routed along an axial direction of the wire harness,

a lid portion attached to the main body to close the routing space portion, and

a plurality of protrusions protruding from one of the main body and the lid portion toward the other of the main body and the lid portion and locking the exterior member,

a height position of a distal end of the plurality of protrusions with respect to a height direction intersecting the axial direction varies according to a formation of the plurality of protrusions,

the main body includes a pair of regulation portions that supports both ends in a width direction of the leaf spring member routed in the routing space portion via the exterior member and regulates a height position of the leaf spring member in the holding member with respect to the height direction intersecting the axial direction, the height position of the distal end of the plurality of protrusions with respect to the leaf spring member supported by the pair of regulation portions varies according to the formation of the plurality of protrusions,

the exterior member has a configuration in which an adhesive tape is wound around a part housed on an inner side of the holding member, and

among the plurality of protrusions, a protrusion corresponding to a region where the adhesive tape is disposed in an axial direction of the holding member is higher in height position of the distal end with respect to the leaf spring member supported by one of the pair of regulation portions via the exterior member than another protrusion corresponding to a region where the adhesive tape is not disposed.

10. The wire harness according to claim 9 , wherein

the exterior member is formed by knitting insulating fibers into a tubular shape.
