Abstract

A wire harness includes: a protector including an accommodating portion and an attachment portion; an electric wire passing through the accommodating portion; a fiber protection member made of a cloth with fibers, having flexibility, and covering at least an area of the electric wire that extends along the attachment portion and an area of the electric wire that extends outward of the protector relative to the attachment portion; and a fastening member fastening the fiber protection member and the attachment portion. The attachment portion has a protrusion protruding from the extension portion toward the fiber protection member and caught by the fibers of the fiber protection member. A part of the fiber protection member that extends in the circumferential direction of the electric wire is covered by the attachment portion, and another part of the fiber protection member is fastened toward the attachment portion by the fastening member.

Claims (40)

1 . A wire harness comprising:

a protector including:

an accommodating portion having a first opening and a second opening; and

an attachment portion provided on the first opening side of the accommodating portion;

an electric wire passing through the accommodating portion via the first opening and the second opening;

a fiber protection member made of a cloth with fibers, having flexibility, and covering at least an area of the electric wire that extends along the attachment portion and an area of the electric wire that extends outward of the protector relative to the attachment portion; and

a fastening member fastening the fiber protection member and the attachment portion by being wound around the fiber protection member and the attachment portion,

wherein

the fiber protection member includes a part that extends in a circumferential direction of the electric wire and is covered by the attachment portion and another part that is fastened toward the attachment portion by the fastening member,

the attachment portion has:

an extension portion extending outside the fiber protection member in an extending direction of the electric wire; and

a protrusion protruding from the extension portion toward the fiber protection member and being caught by the fibers of the fiber protection member, and

the fastening member is provided at a same position as the protrusion in an extending direction of the extension portion.

2 . The wire harness according to claim 1 , wherein the attachment portion has a restricting portion provided on an outer side of the extension portion and restricting a position of the fastening member.

3 . The wire harness according to claim 1 , wherein the protrusion protrudes in a direction in which the protrusion is locked by the fiber protection member when the fiber protection member is pulled outward of the protector.

4 . The wire harness according to claim 3 , wherein

the protector is fixed to a movable member that is to be movably attached to a vehicle body,

an area of the electric wire that is fixed to the protector is movable together with the movable member relative to the vehicle body, and an outer area of the electric wire that extends out from the first opening is to be fixed to the vehicle body, and

the fiber protection member is pulled outward of the protector when the movable member moves.

5 . The wire harness according to claim 1 , wherein a protruding dimension of the protrusion from the extension portion is smaller than or equal to a thickness dimension of the cloth.

6 . The wire harness according to claim 1 , wherein

the fiber protection member is configured to expand along a plane into a tubular shape, the fiber protection member including a first end portion and a second end portion in a circumferential direction of the tubular shape,

an outer diameter of the electric wire is smaller than an inner diameter of the fiber protection member, and

the fiber protection member is further configured to be deformed such that the first end portion and the second end portion overlap each other in a radial direction, and the fastening member maintains the deformed state.

7 . A wire harness comprising:

a protector including:

an accommodating portion having a first opening and a second opening; and

an attachment portion provided on the first opening side of the accommodating portion;

an electric wire passing through the accommodating portion via the first opening and the second opening;

a protection member having flexibility and covering at least an area of the electric wire that extends along the attachment portion and an area of the electric wire that extends outward of the protector relative to the attachment portion; and

a fastening member fastening the protection member and the attachment portion by being wound around the protection member and the attachment portion,

wherein

the protection member includes a part that extends in a circumferential direction of the electric wire and is covered by the attachment portion and another part that is fastened toward the attachment portion by the fastening member,

the attachment portion has:

an extension portion extending outside the protection member in an extending direction of the electric wire; and

a protrusion protruding from the extension portion toward the protection member and engaging with an outer face of the protection member, and

the fastening member is provided at a same position as the protrusion in an extending direction of the extension portion.

8 . The wire harness according to claim 7 , wherein

the protection member is made of a cloth with fibers, and

the protrusion is configured to be caught in the fibers of the protection member.
