Definitions

  • This disclosure relates to exterior components and wire harnesses.
  • the interior part needs to be attached and detached. This makes the work of placing the electric wires complicated. Therefore, in order to easily place the electric wires inside the passenger compartment, it is conceivable to place the electric wires exposed on the outside of the interior part inside the passenger compartment. In this case, it is necessary to consider how to protect the electric wires.
  • the objective of this disclosure is to provide an exterior member and a wire harness that can protect electrical wires placed inside the passenger compartment.
  • FIG. 1 is a schematic diagram of a vehicle equipped with a wire harness according to an embodiment.
  • FIG. 2 is a perspective view showing the wire harness in the embodiment.
  • FIG. 3 is an exploded perspective view showing the wire harness in the embodiment.
  • FIG. 4 is a cross-sectional view showing the wire harness in the embodiment.
  • FIG. 5 is a perspective view for explaining the operation of the wire harness in the embodiment.
  • FIG. 6 is a cross-sectional view showing a wire harness in a modified example.
  • FIG. 7 is a cross-sectional view showing a wire harness in a modified example.
  • This configuration makes it possible to protect the electric wires arranged in the passenger compartment with the cover member.
  • the opening of the storage recess in the cover member is covered with a base member bonded to the tip of each side wall portion, so that the electric wires do not fall out of the storage recess.
  • each side wall portion 62 and the extension portion 65 of one side wall portion 62 are fixed in contact with the first adhesive surface 51 of the second base member 50. This causes the second base member 50 to be attached to the second cover member 60.
  • the opening 64 of the storage recess 63 is covered by the second base member 50. This prevents the electric wire 12b stored in the storage recess 63 from falling out of the opening 64.
  • the electric wire 12b in the storage recess 63 may be adhered to the first adhesive surface 51 of the second base member 50, or the electric wire 12b may not be adhered to the first adhesive surface 51.
  • the side wall portion 62 that does not have the extension portion 65 has an overlapping portion 66 that extends outward in the width direction from the side wall portion 62.
  • the overlapping portion 66 extends from the side wall portion 62 to the side opposite the storage recess 63.
  • the upper surface of the overlapping portion 66 and the upper wall portion 61 are flush with each other.
  • the extension portion 65 extends outward in the width direction from the tip end portion 62b of the corresponding side wall portion 62.
  • the overlapping portion 66 extends outward in the width direction from the base end portion 62a of the corresponding side wall portion 62. Therefore, in contrast to the first cover member 40 having the above-mentioned symmetrical shape, the second cover member 60 has an asymmetrical shape with respect to an axis passing through both the upper wall portion 61 and the storage recess 63 when viewed in its length direction (i.e., in a cross-sectional view along the width direction as shown in FIG. 4).
  • the overlapping portion 66 of the second cover member 60 is located above one of the pair of extension portions 45 of the first cover member 40 in the thickness direction.

More specifically, the thickness of the side wall portion 62 of the second cover member 60 is equal to the thickness T2 of the side wall portion 42 of the first cover member 40. Furthermore, the thickness of the extension portion 65 of the second cover member 60 is equal to the thickness T1 of the extension portion 45 of the first cover member 40. That is, in the second cover member 60, the thickness of the extension portion 65 is set to be smaller than the thickness of the side wall portion 62.
