<About manufacturing method of exterior member>
The exterior member 30 is formed by bending a hot-pressed sheet-like nonwoven member 70. 4 and 5 are developed views showing the hot-pressed sheet-like non-woven member 70, FIG. 6 is a perspective view showing the exterior member 30, and FIG. 7 is a plan view showing the exterior member 30. 8 is a front view showing the exterior member 30, FIG. 9 is a left side view showing the exterior member 30, and FIG. 10 is a right side view showing the exterior member 30.

  The nonwoven member 70 is a sheet formed by hot pressing at least a part of a sheet-like nonwoven material that can be processed with high rigidity by being compressed in a high temperature state. As such a non-woven material, a sheet-like fiber material in which a plurality of fibers are intertwined without being woven, and a material having flexibility can be used. The nonwoven material can be processed to exhibit high rigidity by melting at least a part by heating and further curing.

  Specifically, as the sheet-like nonwoven material, a flexible material including intertwined basic fibers and an adhesive resin (also referred to as “binder”) can be used. The adhesive resin is a resin having a melting point lower than the melting point of the basic fiber. Then, by heating the nonwoven material to a temperature lower than the melting point of the basic fiber and higher than the melting point of the adhesive resin, the adhesive resin melts and soaks between the basic fibers. Thereafter, when the non-woven material reaches a temperature lower than the melting point of the adhesive resin, the adhesive resin is solidified in a state where the basic fibers are bonded to each other. As a result, the nonwoven material is cured and becomes harder than the state before heating. Further, when the nonwoven sheet material is compressed in a state where the adhesive resin is melted, the nonwoven material is maintained in a predetermined molding shape at the time of compression.

  The adhesive resin may be granular or fibrous. An adhesive resin layer may be formed on the outer periphery of the core fiber to form a binder fiber, which may be entangled with the basic fiber. As the core fiber in this case, the same material as the basic fiber can be used.

  As said basic fiber, what is necessary is just to be able to maintain a fiber state with melting | fusing point of adhesive resin, and various fibers other than a resin fiber can be used. As the adhesive resin, thermoplastic resin fibers having a melting point lower than that of the basic fiber can be used. Examples of the combination of the basic fiber and the adhesive resin include an example in which the basic fiber is a resin fiber of PET (polyethylene terephthalate) and the adhesive resin is a copolymer resin of PET and PEI (polyethylene isophthalate). In this case, the melting point of the basic fiber is higher than the melting point of the adhesive resin. For this reason, when the non-woven material is heated to a temperature between the melting points of the basic fiber and the adhesive resin, the adhesive resin is melted and soaked between the basic fibers that keep the fiber shape without melting. When the nonwoven material is at a temperature lower than the melting point of the adhesive resin, the adhesive resin is solidified in a state where the basic fibers are bonded to each other, and the nonwoven material becomes hard and maintains the molded shape during heating. That is, when the nonwoven material is molded into a predetermined shape according to the shape of the predetermined surface by being sandwiched between the predetermined surfaces and compressed in a high temperature state, the molded material is cooled. Maintained in the shape.

  In addition, in order not to completely cut the processed nonwoven material, cut it halfway in the thickness direction, or heat the part other than the linear part of the nonwoven material during the heat compression process to remove the non-heated part. A fold that can be easily folded can be formed in the sheet-like nonwoven material by leaving it soft.

  This non-woven member 70 includes a region 70a corresponding to the bottom surface of the main line portion 22, a region 70c corresponding to the upper surface, regions 70b and 70d corresponding to both side surfaces, and a region 70e superimposed on the lower surface. The lengths of the regions 70d and 70e are shorter than the lengths of the regions 70a, 70b, and 70c. Of the regions 70a, 70b, 70c, 70d, and 70e, the intermediate portion in the extending direction (that is, the portion corresponding to the bendable portion 36) is a region P that is not hot pressed, and both ends of the regions 70a, 70b, 70c, 70d, and 70e. The portion is a region Q that has been hardened by hot pressing.

  In addition, the non-woven member 70 can adjust hardness and softness easily by adjusting the temperature at the time of hot pressing, a heating time, the degree of compression, and the like. For this reason, the area P may be hot-pressed within a range that can maintain a softer state than the area Q.

  These regions 70a, 70b, 70c, 70d, and 70e can be formed in a flat rectangular tube shape by overlapping the region 70e with the region 70a.

  In addition, regions 71a and 71b that close both ends of the main line portion 22 are provided at both ends in the extending direction of each of the regions 70a and 70c. By bending these regions 71a and 71b, the regions 70a, Both ends of the rectangular cylindrical portion formed by 70b, 70c, 70d, and 70e can be closed.

  Further, additional regions 72a and 72b are formed at the intermediate portion in the extending direction of the region 70c. By bending the additional regions 72a and 72b, the side of the first lead portion 40d and the second lead portion 50e is formed. The part can be closed.

  As a result, the trunk line accommodating portion 32 is formed.

  Furthermore, strip-like extension regions 73a and 73b are formed in the outer part of the additional region 72a, and strip-like extension regions 73c and 73e are formed in the middle part in the extension direction of one side of the region 70a. In addition, a strip-shaped extension region 73f is formed in the outer portion of the additional region 72b. And in the state which formed the trunk line part 22 as mentioned above, each extension area | region 73a, 73b, 73c, 73e, 73f is bend | folded in U shape, and the one side part of the trunk line accommodating part 32 is a partition. Thus, the first lead portions 40a, 40b, 40c, 40d and the second lead portions 50e, 50f are formed.

  In addition, it is preferable that the crease L is formed between each area | region among this nonwoven fabric member 70. FIG. Further, an insertion piece 76p is formed at the end of each region of the non-woven member 70, a slit 76s is formed at a position corresponding to the insertion piece 76p, and the insertion piece 76p is inserted into the slit 76s. The bent state is maintained. However, the bent state may be maintained by ultrasonic welding between the non-woven members 70, winding an adhesive tape, or the like.

  In addition, the said exterior member 30 can also be comprised other than the hot-pressed nonwoven member 70. FIG. For example, the exterior member can be manufactured by bending a corrugated cardboard or a plate material such as a corrugated cardboard having a structure formed of plastic. The exterior member can also be manufactured by injection molding in which molten resin is poured into a mold. In these cases, the easily bendable part can be realized by forming a bellows shape or the like.

  However, if it is a non-woven member, there exists an advantage that the trunk line accommodating part 32 can be easily made separately into the bending easy part 36 and the harder part.

<Procedure for assembling a wire harness with an exterior member into a vehicle>

  First, an operator attaches an exterior member in a posture and position in which the first drawers 40a, 40b, 40c, 40d and the second drawers 50e, 50f are opposed to the connectors 126a, 126b, 126c, 126d, 126e, 126f. The wire harness 10 is supported. In this state, at least the connectors 26a, 26b, 26c, and 26f are disposed at positions facing the mating connectors 126a, 126b, 126c, and 126f. The connectors 26d and 26e are also arranged at positions close to the mating connectors 126d and 126e.

  After that, as shown in FIG. 14, the operator collects the connectors 26a, 26b, and 26c at the ends of the connector connection line portions 24a, 24b, and 24c drawn from the first lead portions 40a, 40b, and 40c in a lump. Alternatively, it is grasped sequentially and connected to the mating connectors 126a, 126b, 126c, respectively. At this time, the connectors 26a, 26b, and 26c and the mating connectors 126a, 126b, and 126c are disposed at positions facing each other, so that the connection work can be performed accurately and easily without making a mistake in the connection destination. Similarly, the worker grasps the connector 26d at the end of the connector connection line portion 24d drawn from the first drawing portion 40d and connects it to the mating connector 126d.

  When performing these connection operations, the trunk line accommodating portion 32 can be bent by the bendable portion 36, so that the connectors 26e and 26f are left in a state where they are not connected to the mating connectors 126e and 126f. it can.

Thereby, the connection work of the connectors 26a, 26b, 26c, 26d at the ends of the connector connection line parts 24a, 24b, 24c, 24d, the connection work of the connectors 26e, 26f at the end parts of the connector connection line parts 24e, 24f, etc. Can be easily performed.

  Further, the first lead-out portions 40a, 40b, 40c, 40d and the second lead-out portions 50e, 50f maintain the lead-out positions of the connector connection line portions 24a, 24b, 24c, 24d, 24e, 24f at a fixed position, and Since the main wire portion 22 is drawn outwardly from the outer periphery, the connector connecting wire portions 24a, 24b, 24c, 24d, 24e, and 24f can be easily identified, and the connectors 26a, 26b, 26c, and 26d at the ends thereof are identified. , 26e, and 26f can be easily connected.

  Note that the entire connector does not have to be exposed to the outside from the first drawer portion and the second drawer portion, and the base end portion of the connector may be disposed in the first drawer portion and the second drawer portion.

  Moreover, the non-woven member 70 can easily adjust the hardness and softness by adjusting the presence or absence of hot pressing, the temperature at the time of hot pressing, the heating time, the degree of compression, and the like. Therefore, the outer shape of the main line portion 22 can be maintained in a constant shape by hot pressing a portion other than the bendable portion 36 in the main line accommodating portion 32 so as to be harder than the easy bend portion 36, and Further, it can be easily processed so as to be easily bent by the bending easy portion 36.

  Moreover, since the 1st drawer | drawing-out part 40a, 40b, 40c, 40d and the 2nd drawer | drawing-out part 50e, 50f are opening so that it may face the same direction with respect to the trunk line part 22, the connector connection line part pulled out from these Easily connect the connectors 26a, 26b, 26c, 26d, 26e, 26f at the ends of 24a, 24b, 24c, 24d, 24e, 24f to the mating connectors 126a, 126b, 126c, 126d, 126e, 126f it can.

  In particular, the first lead-out portions 40a, 40b, 40c, 40d and the second lead-out portions 50e, 50f are respectively connected to the connector 26a at the end of the connector connecting line portion 24a, 24b, 24c, 24d, 24e, 24f, 26b, 26c, 26d, 26e, and 26f are provided at positions opposed to the positions of the mating connectors 126a, 126b, 126c, 126d, 126e, and 126f, and therefore the connectors 26a, 26b, 26c, 26d, and 26e are provided. , 26f can be easily and accurately connected.

  In addition, when a surplus length arises in a part or all of the electric wires 21 included in the main line portion 22, as shown in FIG. 18, the surplus length portion 21a may be folded and accommodated in the bendable portion 36. Good. Since the bendable part 36 is kept in a flexible state, it is possible to easily secure a space that can accommodate such an extra length part.
