  However, the above-described wire harness assembly structure 600 tends to increase in size because the sheet materials 602 and 603 have a shape and size corresponding to an assembly location such as a vehicle door. The enlarged wire harness assembly structure 600 has a problem that it requires a large space for storage and is difficult to carry.

  Accordingly, an object of the present invention is to provide a wire harness assembling structure that can be easily carried while reducing the storage space while paying attention to the above problems.

  In order to solve the above-mentioned problems, the invention described in claim 1 includes a wire harness, a sound absorbing sheet formed in a sheet shape with a sound absorbing material, and a thin film sheet formed in a sheet shape thinner than the thickness of the sound absorbing sheet. And a wire harness assembly structure for assembling the wire harness at a predetermined assembly location with the wire harness sandwiched between the sound absorption sheet and the thin film sheet attached to the sound absorption sheet. The sound absorbing sheet is formed with a recessed groove having a thickness thinner than other portions, or a through groove penetrating the sound absorbing sheet, along an intersecting line that obliquely intersects the wire harness. It has a characteristic wire harness assembly structure.

  The invention according to claim 2 is the wire harness assembly structure according to claim 1, wherein the concave groove or the through groove is formed avoiding the wire harness.

Furthermore, according to the first aspect of the present invention, the concave groove and the through groove in the sound absorbing sheet are formed along an intersection line that obliquely intersects the wire harness. For this reason, for example, compared with the case where a ditch | groove and a penetration groove are formed along the crossing line orthogonal to a wire harness, the length of the part which a wire harness and a crossing line overlap becomes long. As a result, when the wire harness assembly structure is folded along the intersection line, the load applied to the wire harness is distributed. Therefore, according to the first aspect of the invention, it is possible to fold the wire harness assembly structure as described above while suppressing the load on the wire harness.
