Abstract

A wire cover includes an inner cover member covering a bent section of an electric wire from an inner peripheral side and an outer cover member covering the bent section from an outer peripheral side. One end portion of the wire cover sandwiches the electric wire along a first direction. The other end portion of the wire cover sandwiches the electric wire along a second direction. The inner cover member and the outer cover member move relative to each other along the first direction. When observed from a third direction intersecting a plane that includes the first direction and the second direction, a first attachment portion and a second attachment portion are positioned outward of the surface of the inner cover body on the innermost side of the bent section or inward of the surface of the outer cover body on the outermost side of the bent section.

First claim

What is claimed is:

1. A wire cover that holds a bent section of an electric wire, the wire cover comprising:
an inner cover member that includes an inner cover body that covers the bent section from an inner peripheral side thereof, a first inner attachment portion provided at one end portion of the inner cover body, and a second inner attachment portion provided at the other end portion of the inner cover body; and
an outer cover member that includes an outer cover body that covers the bent section from an outer peripheral side thereof, a first outer attachment portion provided at one end portion of the outer cover body, and a second outer attachment portion provided at the other end portion of the outer cover body,
wherein the inner cover member and the outer cover member are fixed through attachment of a first attachment portion that includes the first inner attachment portion and the first outer attachment portion and a second attachment portion that includes the second inner attachment portion and the second outer attachment portion,
the one end portion of the inner cover body and the one end portion of the outer cover body sandwich the electric wire along a first direction,
the other end portion of the inner cover body and the other end portion of the outer cover body sandwich the electric wire along a second direction that intersects the first direction,
the first attachment portion and the second attachment portion are positioned outward of a surface of the inner cover body on the innermost side of the bent section or inward of a surface of the outer cover body on the outermost side of the bent section when observed from a third direction that intersects a plane that includes the first direction and the second direction, and
the inner cover member and the outer cover member move relative to each other along the first direction such that the first attachment portion and the second attachment portion are attached to the inner cover member and the outer cover member; and
wherein the inner cover member and the outer cover member are separate pieces that are removably detached from each other along the first direction; and
wherein one of the inner cover member and the outer cover member including a pair of first side walls recessed inwardly from a pair of supporting portions and the other of the inner cover member and the outer cover member includes a pair of second side walls configured to engage a corresponding one of the pair of supporting portions wherein an inner surface of each of the pair of second side walls engage an outer surface of a corresponding one of the pair of first side walls.

2. The wire cover according to claim 1 , wherein, at the one end portions that include the first attachment portion, the inner cover member and the outer cover member engage with each other in all of the first direction, the second direction, and the third direction, and
at the other end portions that include the second attachment portion, the inner cover member and the outer cover member overlap each other in the second direction and the third direction, and engage with each other in the second direction and the third direction of the first direction, the second direction, and the third direction.

3. The wire cover according to claim 2 , wherein, at the other end portions that include the second attachment portion, the inner cover member and the outer cover member overlap each other to form a three-or-more-layered structure along the second direction and the third direction.

4. The wire cover according to claim 3 , wherein, at the other end portions that include the second attachment portion, the inner cover member and the outer cover member overlap each other to form a four-or-more-layered structure along the second direction and the third direction.

5. The wire cover according to claim 2 , wherein a mount portion that is fitted into a rear end portion of a connector is provided at the one end portion of the inner cover body and the outer cover body,
the mount portion includes an internal groove formed in an inner surface of the inner cover body and an external groove formed in an inner surface of the outer cover body, and
a flange portion of the rear end portion of the connector is fitted into the internal groove and the external groove.

6. The wire cover according to claim 1 , wherein a mount portion that is fitted into a rear end portion of a connector is provided at one of the one end portion and the other end portion of the inner cover body and the outer cover body.

7. The wire cover according to claim 1 , wherein a tubular member attaching portion that overlaps a tubular member is provided at the other end portions of the inner cover body and the outer cover body.

8. The wire cover according to claim 1 , wherein a water drainage hole is formed in at least one of the inner cover body and the outer cover body.

9. The wire cover according to claim 1 , wherein the inner cover member and the outer cover member are injection-molded articles obtained using metal molds, and are formed into shapes that have no undercut so as to be removable upward and downward from the metal molds.

10. The wire cover according to claim 1 , wherein the first attachment portion and the second attachment portion are positioned outward of the surface of the inner cover body on the innermost side of the bent section and inward of the surface of the outer cover body on the outermost side of the bent section when observed from the third direction.

11. A wiring member comprising:
an electric wire that includes a bent section that is disposed along a bent path; and
the wire cover according to claim 1 attached to the bent section.
