[Details of the embodiment of the present disclosure]
A specific example of the wiring member of the present disclosure will be described below with reference to the drawings. The present invention is not limited to these examples, but is indicated by the scope of the claims, and is intended to include all modifications within the scope and meaning equivalent to the scope of the claims.

{Embodiment}
A wiring member mounting structure according to the embodiment will be described below. FIG. 1 is a plan view showing a wiring member mounting structure 1 according to the embodiment. FIG. 2 is a cross-sectional view cut along line II-II of FIG. Note that the mounting target member 20 is omitted in FIG.

A wiring member mounting structure 1 is for mounting a wiring member 10 to a mounting target member 20 in an easily attachable and detachable manner. Specifically, the wiring member mounting structure 1 includes a wiring member 10, a mounting target member 20, a convex portion 31, and a concave portion 51 into which the convex portion 31 can be inserted. One of the convex portion 31 and the concave portion 51 is provided on the wiring member 10 , and the other of the convex portion 31 and the concave portion 51 is provided on the mounting target member 20 . In the wiring member mounting structure 1 , an elastic deformation portion 55 is formed in at least one of the convex portion 31 and the concave portion 51 . The convex portion 31 and the concave portion 51 are attached to each other by the elastic deformation portion 55 so as to be easily detachable.

The wiring member 10 is mounted on the vehicle and transmits electricity, light, or the like to each component mounted on the vehicle. The wiring member 10 includes a linear transmission member 12 . Here, an example in which the wiring member 10 is a flat wiring member 10 including a plurality of linear transmission members 12 and a base member 16 that keeps the plurality of linear transmission members 12 flat will be described.

The linear transmission member 12 may be any linear member that transmits electricity, light, or the like. For example, the linear transmission member 12 may be a general electric wire having a core wire and a coating around the core wire, or may be a bare conductor wire, a shielded wire, an enameled wire, a nichrome wire, an optical fiber, or the like.

Various signal lines and various power lines may be used as the linear transmission member 12 for transmitting electricity. A linear transmission member 12 that transmits electricity may be used as an antenna, a coil, or the like that transmits or receives signals or power to or from space.

Here, it is assumed that the linear transmission member 12 is a general electric wire 12 (hereinafter simply referred to as the electric wire 12). The electric wire 12 has a core wire 13 as a transmission line body and an insulating coating 14 as a coating that covers the core wire 13 . Each description regarding the wire 12 is applicable to each example of the linear transmission member 12, except for inapplicable configurations.

The core wire 13 is composed of one or more strands. The strands are made of conductors such as copper, copper alloys, aluminum, and aluminum alloys. When the core wire 13 is composed of a plurality of strands, the strands may be twisted. The insulating coating 14 is formed by extrusion molding a resin material such as PVC (polyvinyl chloride) or PE (polyethylene) around the core wire 13 . Here, the wire 12 is a so-called round wire 12 having a circular cross section.

The base member 16 is a member that holds the electric wire 12 in a two-dimensionally positioned state. The base member 16 only needs to be able to hold the electric wire 12 in a two-dimensionally positioned state when placed on a work site or the like. Thus, the base member 16 may be a flexible sheet-like member that can be easily bent. The base member 16 may be a sheet-shaped member having a degree of rigidity capable of holding the electric wires 12 in a two-dimensionally positioned state while being curved, or may be a sheet-like member that holds the electric wires 12 in a two-dimensional state while maintaining a flat state. It may be a sheet-shaped member having a rigidity that allows it to be held in a state in which it is positioned at the right position. The base member 16 may have a three-dimensional shape, such as a partly erected wall.

Here, the base member 16 is described as being a bendable sheet member 16 . Each description of seat member 16 is applicable to base member 16, except where not applicable.

The material forming the sheet member 16 is not particularly limited, but the sheet member 16 is preferably made of a material containing a resin such as PVC (polyvinyl chloride), PET (polyethylene terephthalate), PP (polypropylene), or the like. be. The sheet member 16 may be a sheet member 16 whose interior is uniformly filled, or may be a non-woven sheet or the like. Sheet member 16 may also comprise a material such as metal. The sheet member 16 preferably has flexibility to be easily bent in the thickness direction. The sheet member 16 may be a single layer, or may be laminated in multiple layers. When a plurality of layers are laminated, it is conceivable that resin layers and resin layers are laminated, for example. Further, for example, it is conceivable that a resin layer and a metal layer are laminated.

The electric wire 12 is fixed on one main surface of the sheet member 16 . On one main surface of the sheet member 16, the electric wire 12 is fixed along a certain route. In the example shown in FIG. 1, the path of the electric wire 12 on the sheet member 16 is a straight line, but it may be a curved path. Further, when a plurality of electric wires 12 are fixed on one main surface of the sheet member 16, the plurality of electric wires 12 may or may not branch in the middle.

The sheet member 16 is formed in a shape along the paths of the plurality of electric wires 12 . At this time, the sheet member 16 includes a strip-shaped portion 17 along the path of the electric wire 12 and an extension portion 18 extending laterally from the strip-shaped portion 17 . The electric wire 12 is fixed to the belt-like portion 17 . The extending portion 18 is provided with a convex portion 31 or a concave portion 51 .

The mode of fixing the electric wire 12 and the sheet member 16 may be fixed at the contact portion, may be fixed at the non-contact portion, or both may be used together. Here, the fixing of the contact portion means that the contact portion between the electric wire 12 and the sheet member 16 is stuck and fixed. Non-contact site fixation is a fixation mode that is not contact site fixation. For example, a thread, another sheet member 16, adhesive tape, or the like may hold the wire 12 against the sheet member 16, or a thread, another sheet member 16, adhesive tape, or the like may surround the wire 12 and the sheet member 16. The electric wire 12 and the sheet member 16 are sandwiched between the electric wires 12 and the sheet member 16 to maintain the state in which the electric wires 12 and the sheet member 16 are fixed. In the following description, it is assumed that the electric wire 12 and the sheet member 16 are in a fixed contact portion state. Each discussion relating to contact site fixation is also applicable to non-contact site fixation, unless the configuration is not applicable.

Such contact site fixation may be indirect fixation at the contact site, direct fixation at the contact site, or both may be used in different regions. Here, the indirect fixation of the contact portion means that the electric wire 12 and the sheet member 16 are indirectly fixed by intervening an intervening member such as an adhesive, a pressure sensitive adhesive, or a double-sided adhesive tape provided between them. be. Further, the direct fixation of the contact portion means that the electric wire 12 and the sheet member 16 are directly adhered and fixed without an adhesive or the like provided separately. In the direct fixation of the contact portion, it is conceivable that, for example, resin contained in at least one of the electric wire 12 and the sheet member 16 is melted to stick and fix. In the following description, it is assumed that the electric wire 12 and the sheet member 16 are directly fixed at their contact portions. Each discussion relating to direct contact site fixation is also applicable to indirect contact site fixation, unless the configuration is not applicable.

In forming such a state in which the contact portion is directly fixed, the resin may be melted, for example, by heat or melted by a solvent. That is, the state of direct fixation of the contact portion may be the state of direct fixation of the contact portion by heat or the state of direct fixation of the contact portion by solvent. Preferably, the contact portion is directly fixed by heat.

At this time, the means for forming the state of direct fixation of the contact portion is not particularly limited, and various means including known means such as welding, fusing and welding can be used. For example, when the contact portion is directly fixed by heat by welding, various welding means such as ultrasonic welding, heat-pressure welding, hot-air welding, and high-frequency welding can be employed. Further, when the contact portion directly fixed state is formed by these means, the electric wire 12 and the sheet member 16 are brought into the contact portion directly fixed state by the means. Specifically, for example, when the contact portion directly fixed state is formed by ultrasonic welding, the electric wire 12 and the sheet member 16 are brought into the contact portion directly fixed state by ultrasonic welding. The portion (fixed portion between the electric wire 12 and the sheet member 16) in which the contact portion is directly fixed by heat by welding is the welded portion, and the portion fixed by ultrasonic welding is the ultrasonic welded portion. The fixed portion may also be referred to as a heating/pressurizing welding portion or the like.

In the case of directly fixing the contact portion, only the resin contained in the coating of the electric wire 12 may be melted, or only the resin contained in the sheet member 16 may be melted. In these cases, the melted resin may become stuck to the outer surface of the other, forming a relatively sharp interface. Moreover, in the case of directly fixing the contact portion, both the resin contained in the coating of the electric wire 12 and the resin contained in the sheet member 16 may be melted. In this case, both resins may mix and a clear interface may not be formed. In particular, when the coating of the electric wire 12 and the sheet member 16 contain resins that are easily compatible, such as the same resin material, both resins may be mixed and a clear interface may not be formed.

The attachment target member 20 is an attachment target of the wiring member 10 . Here, an example in which the mounting target member 20 is the vehicle body will be described. The vehicle body includes, for example, frames, panels, reinforcing members, and the like. In the example shown in FIG. 2 , the attachment target member 20 is a flat panel 20 . A mounting hole 20 h is formed in the mounting target member 20 .

Here, an example in which the wiring member 10 is provided with the convex portion 31 and the attachment target member 20 is provided with the concave portion 51 will be described. Here, an example in which a male mounting member 30 is provided separately from the wiring member 10 and the mounting target member 20 as the member including the convex portion 31 will be described. Further, here, an example in which a female mounting member 50 corresponding to the male mounting member 30 is provided separately from the wiring member 10 and the mounting target member 20 as the member including the recessed portion 51 will be described. do. In particular, here, a male snap fastener 30 is adopted as the male mounting member 30, and a female snap fastener 50 corresponding to the male snap fastener 30 is adopted as the female mounting member 50. I will explain with an example. A snap fastener is a member also called a snap button or the like, and a pair of a male snap fastener 30 and a female snap fastener 50 is, for example, a member used as a snap to fasten parts of cloth to be joined together in apparel applications. can be used. That is, here, among the snaps having a pair of recesses and protrusions, the convex snap fastener 30 is used as the male snap fastener 30 and the concave snap fastener 50 is used as the female snap fastener 50 .

The male snap fastener 30 includes a convex portion 31 as well as a first attachment structure. The first attachment structure portion is a portion for attaching the male snap fastener 30 itself to a member (here, the wiring member 10) on which the convex portion 31 is provided. Here, an example in which the first mounting structure portion is formed in a shape capable of sandwiching the wiring member 10 will be described.

A male snap fastener 30 is attached to the sheet member 16 of the wiring member 10 . A male snap fastener 30 is attached to the extension 18 of the seat member 16 . A male snap fastener 30 is attached to the extension 18 using a through hole 18 h formed in the extension 18 . Therefore, in this example, an example in which the first mounting structure portion is formed so as to sandwich the peripheral portion of the through hole 18h of the extension portion 18 will be described.

FIG. 3 is an exploded cross-sectional view of the male snap fastener 30. As shown in FIG.

Specifically, the snap fastener 30, here male, is made up of a plurality of separately molded parts. In the example shown in FIG. 3, male snap fastener 30 comprises a separately molded male body portion 32 and clasp 36 . The male snap fastener 30 is made of metal or resin, for example.

The male body portion 32 has a fitting head portion 33 for attaching the male snap fastener 30 to the female snap fastener 50, and a flange portion 34 extending outwardly from the base end of the fitting head portion 33. . Here, the fitting head 33 is formed in a tubular shape.

The fastener 36 penetrates the member to which the male snap fastener 30 is attached (here, the sheet member 16), and is inserted into the fitting head 33. and a flange portion 38 extending outward from the base end portion.

Here, the male snap fastener 30 is attached to the wiring member 10 by sandwiching the sheet member 16 between the flange portions 34 and 38 . At this time, by inserting the mounting head portion 37 penetrating the sheet member 16 into the fitting head portion 33, a state in which a portion of the sheet member 16 is sandwiched between the flange portions 34 and 38 is maintained. ing. More specifically, when the mounting head 37 passing through the sheet member 16 is inserted into the fitting head 33 , the leading end of the mounting head 37 is crimped, and the inner surface of the fitting head 33 is bent. It plastically deforms into a shape that conforms to its shape. For example, after the tip of the mounting head 37 inserted into the fitting head 33 abuts against the inner surface of the fitting head 33 while the outer surface of the fitting head 33 is supported by a jig or the like. , and plastically deforms into a shape corresponding to the shape of the inner surface of the fitting head 33 by receiving force from the inner surface of the fitting head 33 . As a result, the mounting head 37 is prevented from detenting from the fitting head 33 , and the flanges 34 and 38 are maintained in a state of holding the wiring member 10 therebetween.

Therefore, in the male snap fastener 30, the clamping structure by the flanges 34, 38 and the detent structure of the mounting head 37 from the fitting head 33 for maintaining it are sufficient for the male snap fastener 30 to be wired. It can be regarded as a first mounting structure for mounting to the member 10 . In the male snap fastener 30 , the fitting head portion 33 and the mounting head portion 37 are formed as the convex portion 31 .

4 is an exploded cross-sectional view of the female snap fastener 50. FIG.

The female snap fastener 50 includes a second attachment structure in addition to the recessed portion 51 . The second attachment structure portion is a portion for attaching the female snap fastener 50 itself to a member (here, the member to be attached 20) to which the recessed portion 51 is attached. Specifically, the snap fastener 50, here female, is made up of a plurality of separately molded parts. In the example shown in FIG. 4, the female snap fastener 50 consists of a separately molded female body portion 52 and a receiving portion 56 . The female snap fastener 50 is made of metal or resin, for example.

The female body portion 52 includes a cylinder 53 , a retaining plate 54 and a ring spring 55 . The cylindrical body 53, the holding plate 54, and the ring spring 55 are separately molded members. A concave portion 51 is a hole formed in the female main body portion 52 so as to communicate with the inside of the cylinder 53 , the holding plate 54 , and the ring spring 55 .

As shown in FIG. 4, the cylindrical body 53 has a small cylindrical portion 53a and a large cylindrical portion 53b having a larger diameter than the small cylindrical portion 53a before the female snap fastener 50 is attached to the mounting target member 20. , and a flange portion 53c having a diameter larger than that of the large cylinder portion 53b are formed in a continuous shape from one axial side to the other axial side. The small cylindrical portion 53 a is a portion that is crimped and plastically deformed when the female snap fastener 50 is attached to the attachment target member 20 . Here, the small cylindrical portion 53a has a length dimension and a diameter dimension that allow it to pass through the attachment hole 20h formed in the member 20 to which the female snap fastener 50 is attached. A ring spring 55 is accommodated inside the large cylindrical portion 53b. A stepped portion is formed between the large cylindrical portion 53b and the small cylindrical portion 53a to prevent the ring spring 55 from coming off. The flange portion 53 c is a portion held by the holding plate 54 .

The holding plate 54 has a through hole 54h formed in the center of the disk-shaped member coaxial with the small cylindrical portion 53a, and the outer peripheral portion is deformed so as to warp to hold the flange portion 53c. A through hole 54 h of the holding plate 54 is set smaller than the outer diameter of the ring spring 55 . As a result, the ring spring 55 can be detented while the holding plate 54 is held by the flange portion 53c.

The ring spring 55 is the elastic deformation portion 55 described above. Moreover, since the convex portion 31 is inserted into the ring spring 55 , the ring spring 55 can also be regarded as part of the concave portion 51 . The outer diameter of the ring spring 55 in the natural state is smaller than the inner diameter of the large cylindrical portion 53b. As a result, the ring spring 55 is elastically deformable so as to spread outward. In addition, the inner diameter of the ring spring 55 is smaller than the inner diameter of the small cylindrical portion 53a and the through hole 54h of the holding plate 54 in the natural state. As a result, the inner peripheral portion of the ring spring 55 is the narrowest portion of the concave portion 51 .

The receiving portion 56 is formed in a disc shape, for example. Further, the receiving portion 56 is formed with an insertion hole 56h through which the small cylindrical portion 53a can be inserted.

The female snap fastener 50 is attached to the attachment target member 20 as follows. That is, in a state in which the female main body portion 52 is positioned on one side of the mounting target member 20 and the receiving portion 56 is positioned on the other side of the mounting target member 20, the small tubular portion 53a of the female main body portion 52 is It penetrates through an attachment hole 20 h formed in the attachment target member 20 and an insertion hole 56 h formed in the receiving portion 56 . Then, the distal end portion of the small cylindrical portion 53a of the female main body portion 52 passing through the mounting hole 20h formed in the mounting target member 20 and the insertion hole 56h formed in the receiving portion 56 is crimped, and the rear surface of the receiving portion 56 is crimped. is plastically deformed so as to hold the

Therefore, in the female snap fastener 50, the pinching structure by the female main body portion 52 and the receiving portion 56 and the caulking structure of the female main body portion 52 for maintaining it are necessary for attaching the female snap fastener 50 to the attachment target member 20. can be regarded as the second mounting structure of the .

The convex portion 31 includes a first insertion portion 31a that is gradually widened from the front end side toward the rear end side in the direction of insertion into the concave portion 51, and a first insertion portion 31a that extends toward the concave portion 51 with respect to the first insertion portion. A second insertion portion 31b is located on the rear end side in the insertion direction and formed to gradually narrow from the front end side in the insertion direction to the recessed portion 51 toward the rear end side. The widest portion of the convex portion 31 exists between the first insertion portion 31a and the second insertion portion 31b.

The concave portion 51 includes a first inserted portion 51a formed to gradually widen from the front end side into which the convex portion 31 is inserted toward the rear end side, and a convex portion with respect to the first inserted portion 51a. and a second inserted portion 51b which is positioned on the rear end side of the insertion direction of the convex portion 31 and formed to gradually narrow from the front end side of the convex portion 31 toward the rear end side thereof in the insertion direction. Here, since the ring spring 55 is formed to have a circular cross section, the first inserted portion 51a and the second inserted portion 51b are formed in the inner peripheral portion of the ring spring 55 so as to be aligned in the axial direction. .

When the convex portion 31 is inserted into the concave portion 51 by receiving the force in the first direction, the elastically deforming portion 55 is elastically deformed by the force in the first direction so that the convex portion 31 and the concave portion 51 are separated from each other. and are mated. Further, when the convex portion 31 is pulled out from the concave portion 51 by receiving a force in a second direction opposite to the first direction, the elastic deformation portion 55 is deformed in the first direction by the force in the second direction. The convex portion 31 and the concave portion 51 are disengaged by elastic deformation in the same direction as when the force is applied.

The elastic deformation portion 55 is provided in the concave portion 51 . The elastically deformable portion 55 can widen the concave portion 51 when the first insertion portion 31a is inserted when the convex portion 31 and the concave portion 51 are attached, and can be concave when the second insertion portion 31b is inserted. It is formed so that the portion 51 can be narrowed. The elastically deforming portion 55 is formed so as to expand the recessed portion 51 when the second insertion portion 31b is inserted when the convex portion 31 and the recessed portion 51 are detached.

More specifically, a ring spring 55 is provided here as the elastic deformation portion 55 . When the convex portion 31 and the concave portion 51 are attached, that is, when the male snap fastener 30 and the female snap fastener 50 are attached, the first insertion portion 31 a of the convex portion 31 is inserted into the ring spring 55 . When this is done, the ring spring 55 is expanded by the first insertion portion 31a. When the second insertion portion 31b is inserted after the convex portion 31 has passed through the first insertion portion 31a, the ring spring 55 is elastically restored and narrowed. As a result, the ring spring 55 is fitted into the recessed portion of the convex portion 31 to prevent slippage and detent, and the male snap fastener 30 and the female snap fastener 50 are attached.

On the other hand, when the convex portion 31 and the concave portion 51 are released, that is, when the male snap fastener 30 and the female snap fastener 50 are released, the second insertion portion 31b of the convex portion 31 is disengaged. When inserted into the ring spring 55, the ring spring 55 is expanded by the second insertion portion 31b. As a result, the convex portion 31 can pass through the ring spring 55, and by passing through, the male snap fastener 30 and the female snap fastener 50 are disengaged. When the first insertion portion 31a is inserted into the ring spring 55 after the second insertion portion 31b of the convex portion 31 has passed, the ring spring 55 is elastically restored and narrowed. As a result, the male snap fastener 30 and the female snap fastener 50 can be attached again.

According to the wiring member mounting structure 1 configured as described above, when the convex portion 31 is inserted into the concave portion 51 and when the convex portion 31 is extracted from the concave portion 51, the same elastic deformation portion 55 is also elastically deformed. This facilitates removal of the wiring member 10 from the mounting target member 20 .

The fitting head 133 is formed in a cylindrical shape. A circumferential groove 133h is formed on the outer surface of the cylindrical fitting head 133. As shown in FIG. A ring spring 55 is accommodated in the circumferential groove 133h. The fitting head 133 and the ring spring 55 form the convex portion 131 . As in this example, the elastic deformation portion 55 may be provided on the convex portion 131 . The flange portion 134 is provided so as to protrude sideways from the base end portion of the fitting head portion 133 . The flange portion 134 has an opening 134a through which the tip of the fastener 136 that has passed through the sheet member 16 is inserted, and a receiving plate portion 134b that plastically deforms the tip of the fastener 136 that has passed through the opening 134a. The tip of the fastener 136 passing through the member 16 is formed to be accommodated while being plastically deformed.

The ring spring 55 housed in the circumferential groove 133h protrudes outward from the fitting head 133 in a natural state. The ring spring 55 is accommodated in the circumferential groove 133h so as to be elastically deformable so as to narrow. The elastically deforming portion 55 provided in the convex portion 131 can narrow the convex portion 131 when the convex portion 131 is inserted into the concave portion 151, and the convex portion 31 can be inserted into the concave portion 151. It is formed so that the convex portion 131 can be expanded after insertion.

The fastener 136 includes a plurality of claw portions 40 that are spaced apart in the circumferential direction, a connecting portion 41 that connects the base end portions of the plurality of claw portions 40, and a flange that extends outwardly from the connecting portion 41. and a portion 138 . The tip portion of the claw portion 40 is sharpened so as to be able to pass through a non-perforated portion of the sheet member 16 before being attached to the sheet member 16 .

The female main body portion 252 has a cylindrical body 253 and a substrate 254 on which the cylindrical body 253 is erected. The cylindrical body 253 is formed larger than the fitting head 233 so that the fitting head 233 can be inserted therein. Therefore, the tubular body 253 is the concave portion 251 . A protrusion 253 a is formed on the inner peripheral surface of the tip of the cylindrical body 253 . The protrusion 253a has a first inserted portion 253b and a second inserted portion 253c located closer to the base end side of the cylinder 253 than the first inserted portion 253b. The first inserted portion 253b is a portion that gradually narrows the width of the opening from the opening side (the distal end side of the cylinder 253) toward the back side (the proximal end side of the cylinder 253). The second inserted portion 253c is a portion that gradually widens the width of the opening from the opening side toward the back side. A through hole 254 h is formed in the substrate 254 . The cylindrical body 253 is provided at a position avoiding the periphery of the through hole 254h on the substrate.

The fastener 256 has a substrate 258 and a cylindrical claw portion 260 erected on the substrate 258 . The distal end of the claw portion 260 is wider than the proximal end and is formed so as to be able to be inserted into and engaged with a through hole 254h formed in the substrate 254 of the female body portion 252 . With the attachment target member 20 sandwiched between the base plate 254 of the female main body portion 252 and the base plate 258 of the fastener 256, the tip of the claw portion 260 is inserted into the through hole 254h and locked, thereby forming the female mold. A snap fastener 250 is attached to the attachment target member 20 .

When the convex portion 231 is inserted into the concave portion 251, the protrusions 233a and 253a, more specifically, the first inserted portion 233b of the protrusion 233a and the first inserted portion 253b of the protrusion 253a come into contact with each other. At this time, in the fitting head 233, the base end side portion of the projection 233a is elastically deformed, and the portion of the fitting head 233 having the projection 233a moves toward the inner peripheral side. Also, in the cylindrical body 253, the portion closer to the proximal end than the projection 253a is elastically deformed, and the portion of the cylindrical body 253 having the projection 253a moves toward the outer peripheral side. As a result, the protrusions 233a and 253a pass through each other, and after passing, they are elastically restored to fit the convex portion 231 into the concave portion 251. As shown in FIG.

When the convex portion 231 is pulled out from the concave portion 251, the projections 233a, 253a, more specifically, the second insertion portion 233c of the projection 233a and the second inserted portion 253c of the projection 253a come into contact with each other. At this time, in the fitting head 233, the base end side portion of the projection 233a is elastically deformed, and the portion of the fitting head 233 having the projection 233a moves toward the inner peripheral side. Also, in the cylindrical body 253, the portion closer to the proximal end than the projection 253a is elastically deformed, and the portion of the cylindrical body 253 having the projection 253a moves toward the outer peripheral side. As a result, the protrusions 233 a and 253 a pass through each other, and the convex portion 31 is separated from the concave portion 51 .

In this example, both the fitting head portion 233, which is the convex portion 231, and the tubular body 253, which is the concave portion 251, are elastically deformable. That is, in this example, the elastically deformable portion is integrally formed with both the convex portion 231 and the concave portion 251 . Thus, the elastically deformable portion may be formed integrally with the convex portion, the concave portion, or both. Also, as in this example, the elastically deformable portion may be provided on both the convex portion and the concave portion.

In this example, the male snap fastener 30 and the female snap fastener 50 are elastically deformed and attached to the wiring member 10 and the attachment target member 20 . In this manner, the male snap fastener 30 and the female snap fastener 50 may be attached to the wiring member 10 and attachment target member 20 in a manner other than plastic deformation. For example, the male snap fastener 30 and the female snap fastener 50 may be attached to the wiring member 10 and attachment target member 20 by sewing, bonding, or the like.

15 to 17 are cross-sectional views showing modifications of the attachment target member 20. FIG.

At this time, in the example shown in FIG. 15, two flat wiring members 10 are laminated. Further, in the example shown in FIG. 16, two flat wiring members 10 are connected so as to expand sideways. In the examples shown in FIGS. 15 and 16, the two flat wiring members 10 are attached so that the respective linear transmission members 12 are parallel to each other, but this is not the only option. The two flat wiring members 10 may be attached such that the respective linear transmission members 12 cross each other.

Further, in the above description, when the mounting target member 20 is the vehicle body, the flat wiring member 10 is mounted along the plane portion of the vehicle body, but this is not an essential configuration. For example, as shown in FIG. 17, the flat wiring member 10 may be attached along the curved surface of the vehicle body.

More specifically, the attachment target member 120 is a vehicle body 120 having a curved surface 22 . An intermediate portion along the width direction of the flat wiring member 10 is bent along the curved surface 22 of the vehicle body 120 . Both ends along the width direction of the flat wiring member 10 are attached to the vehicle body 120 by the convex portion 31 and the concave portion 51 . According to this aspect, the flat wiring member 10 can be bent along the curved surface 22 of the vehicle body 120 .

FIG. 18 is a cross-sectional view showing a modification of the snap fastener.

That is, the snap fastener 270 is a hermaphroditic snap fastener 270 . For example, the hermaphroditic snap fastener 270 may be formed by fastening the male main body portion 232 and the female main body portion 252 with a rivet R or the like in a state in which they are positioned opposite to each other with the sheet member 16 interposed therebetween. Conceivable.

A female snap fastener 250 is attached to the convex portion 231 of the hermaphroditic snap fastener 270 and a male snap fastener 230 is attached to the concave portion 251 of the hermaphroditic snap fastener 270 . In this manner, one wiring member 10 is attached to another wiring member 10 and the vehicle body 20 as the first and second attachment target members by the hermaphroditic snap fasteners 270 . Of course, three or more stacked wiring members 10 may be attached by hermaphroditic snap fasteners 270 . According to this aspect, more than two members can be attached. It goes without saying that a hermaphroditic snap fastener 270 may be provided instead of the male snap fastener 230 and the female snap fastener 250 . Hermaphroditic snap fastener 270 is a variation of male snap fastener 230 and may also be viewed as a variation of female snap fastener 250 .
