The

  Next, a procedure for fixing the wire harness 4 to the head liner 3 will be described with reference to FIG.

  The wire harness 4 is fixed to the headliner 3 using a plurality of the fixing members 11 described above. Each fixing member 11 holds a part of the wire harness 4 in the holding portion 13 and is attached to an appropriate portion of the wire harness 4. The wire harness 4 is routed on the head liner 3 along a predetermined path, and each fixing member 11 attached to each part of the wire harness 4 applies the hot melt adhesive layer 22 of the fixing portion 12 to the head liner 3. It is arranged in contact with.

  When the fixing member 11 attached to the wire harness 4 is arranged on the head liner 3, the fixing member 11 is accurately arranged at a desired position on the head liner 3 by the mounting jig 6. Here, the structure of the mounting jig 6 will be described, and a method of arranging the fixing member 11 on the head liner 3 using the mounting jig 6 will be described.

  First, the structure of the mounting jig 6 will be described. As shown in FIG. 5, the mounting jig 6 has recesses for accommodating the fixing members 11 on the bottom surface (the mounting jig 6 contacts the head liner 3 as many as the fixing members 11 arranged on the head liner 3. Formed on the upper surface of the headliner 3 at the time of contact. The opening part of this recessed part is formed in the shape along the outer periphery of the top-plate part 51, the two side-plate parts 52a and 52b, and the two board | substrate parts 21a and 21b when the fixing member 11 is top view. The depth of the recess is preferably the same as the height of the fixing member 11 (the length from the tip of the locking member 41 to the lower surface of the hot melt adhesive layer 22) or shallower than the height of the fixing member 11. . This is because the hot melt adhesive layer 22 is sufficiently pressed against the upper surface of the head liner 3 when the fixing member 11 is disposed on the head liner 3 with the fixing member 11 being accommodated in the recess. . The mounting jig 6 having such a structure is fixed to a work table (not shown in FIG. 5) on which the head liner 3 is placed. Since the head liner 3 is also placed at a desired position on the work table, the lower surface of the mounting jig 6 fixed to the work table and the upper surface of the head liner 3 are brought into contact with each other. By moving the mounting jig 6, the fixing member 11 accommodated in the recess of the mounting jig 6 can also be accurately placed at a desired position on the head liner 3. As a result, the wire harness 4 with the fixing member 11 mounted thereon is also accurately placed at a desired position on the headliner 3.

  After the fixing member 11 is arranged on the head liner 3 in this way, the entire head liner 3 is heated using, for example, a warm air heater or the like, or the spot where each fixing member 11 is arranged is spot-heated to fix each fixing member 11. The hot melt adhesive layer 22 of the fixing portion 12 of the member 11 is fused to the head liner 3, and the fixing portion 12 is fixed to the head liner 3. Thereby, the wire harness 4 is fixed to the head liner 3.

  For fixing the fixing portion 12 of the fixing member 11 to the headliner 3, for example, a double-sided pressure-sensitive adhesive tape can be used instead of the hot melt adhesive layer 22. Note that fixing by the hot melt adhesive layer 22 is preferable because accurate positioning can be performed before heating and an error can be prevented from occurring in the fixed position.

  Refer to FIG. 1 again. In the attachment structure 1, the headliner 3 in which the wire harness 4 is routed and fixed is attached to the roof panel 2.

  The mounted portion 16 is a loop-shaped locking body with respect to the locking member 41 of the mounting portion 14 provided with a large number of either the loop-shaped locking body or the hook-shaped locking body that is hooked on the loop-shaped locking body. Alternatively, a locking member 42 provided with a large number of other hook-shaped locking bodies is joined to the above-mentioned facing portions of the roof panel 2.

  When the head liner 3 is pressed against the vehicle body liner 2, the locking member 41 of the mounting portion 14 of each fixing member 11 comes into contact with the locking member 42 of the mounted portion 16 of the roof panel 2, and both locking members 41, 42 are brought into contact. The locking bodies engage with each other. As a result, the attachment portion 14 of each fixing member 11 is attached to the roof panel 2, and the head liner 3 is attached to the roof panel 2 via these fixing members 11.

  As described above, the locking members 41 and 42 in which a large number of loop-shaped locking bodies or hook-shaped locking bodies are provided on the mounting portion 14 of the fixing member 11 and the mounting portion 16 of the roof panel 2 are used in cooperation with the mounting portion 16. The example in which the mounting portion 14 is attached to the roof panel 2 has been described. In this way, if the mounting portion 14 is attached to the roof panel 2 in cooperation with the mounted portion 16, various configurations can be adopted. For example, magnets can be used instead of the locking bodies 41 and 42. When a magnet is used, the roof panel 2 is generally formed of a steel material and attracts the magnet. Therefore, the magnet is joined only to the mounting portion 14 of the fixing member 11, and the roof portion 2 alone is attached to the mounting portion 14. It can also be attached to.
