[0010] [Description of the embodiments of the present disclosure] First, the embodiments of the present disclosure will be listed and described. The wire harness of the present disclosure includes: [1] A wire harness comprising an electric wire bundle having a plurality of electric wires, the electric wire bundle having a flat portion in which the plurality of electric wires are arranged flat in at least a portion in an extension direction of the electric wire bundle, and the wire harness comprising a first tape member and a second tape member bonded together from both sides in a thickness direction of the flat portion, sandwiching the flat portion therebetween.

[0011] According to this configuration, by bonding the first tape member and the second tape member together, the flat portion sandwiched between the first tape member and the second tape member can be maintained in a state in which the multiple electric wires are arranged flat. Therefore, the multiple electric wires in the flat portion can be easily maintained flat by the first tape member and the second tape member.

[0012] [2] In the above [1], each of the first tape member and the second tape member may be strip-shaped and extend along the extension direction of the electric wire bundle. With this configuration, the plurality of electric wires in the flat portion can be easily maintained flat over the range in which the first tape member and the second tape member are attached along the extension direction of the electric wire bundle.

[0013] [3] In the above [1] or [2], the first tape member and the second tape member may be directly attached to each other on both sides of the flat portion in the width direction. According to this configuration, the second tape member is prevented from moving relative to the first tape member. Therefore, the first tape member and the second tape member can more easily maintain the plurality of electric wires in the flat portion in a flat shape. In addition, the first tape member and the second tape member can surround the entire outer periphery of the flat portion. Therefore, when the wire harness is arranged, the first tape member and the second tape member can prevent the surrounding members and the like from directly contacting the flat portion. In other words, the wire harness can be protected.

[0014] [4] In any one of the above [1] to [3], at least one of the first tape member and the second tape member may be attached to at least a part of an outer circumferential surface of at least one of the electric wires located between the first tape member and the second tape member. With this configuration, it is easier to maintain the plurality of electric wires in the flat portion in a state where they are arranged flatly.

[0015] [5] In any one of the above [1] to [4], at least one of the first tape member and the second tape member may have an arc-shaped attachment portion that is attached to an outer circumferential surface of at least one of the electric wires located between the first tape member and the second tape member and forms an arc shape along the outer circumferential surface. With this configuration, it is easier to maintain the plurality of electric wires in the flat portion in a state where they are arranged flatly.

[0016] [6] In any of the above [1] to [5], the first tape member and the second tape member may be directly attached to each other between adjacent electric wires in the flat portion. According to this configuration, in the flat portion, the multiple electric wires are maintained apart in the width direction of the flat portion by the first tape member and the second tape member. Therefore, the surface area of ​​the portion where the first tape member and the second tape member cover the electric wires can be made larger than when adjacent electric wires in the width direction of the flat portion are in contact with each other. Therefore, the heat dissipation in the flat portion can be improved.

[0017] [7] In any of the above [1] to [6], each of the first tape member and the second tape member may have a plurality of tapes overlapped with each other in the thickness direction of the flat portion. According to this configuration, the thickness of each of the first tape member and the second tape member in the thickness direction of the flat portion can be adjusted by adjusting the number of tapes. Also, each of the first tape member and the second tape member can be constructed of a plurality of types of tape.

[0018] [8] In any of [1] to [7] above, at least one of the first tape member and the second tape member may include at least one of: an electric wire tie tape used for bundling electric wires, having a band-shaped base material and an adhesive layer laminated on one side of the base material; a protective tape having a base material thicker than the base material of the electric wire tie tape and an adhesive layer laminated on one side of the base material; a sound-absorbing tape having a band-shaped porous base material; a heat-resistant tape having better heat resistance than the electric wire tie tape; a metal tape having a band-shaped metal base material; a double-sided tape having a band-shaped base material and adhesive layers laminated on both sides of the base material; a band-shaped hook-and-loop fastener; and a magnetic tape having a base material which is a band-shaped magnet.

[0019] According to this configuration, since the electric wire binding tape is easy to obtain, when at least one of the first tape member and the second tape member includes the electric wire binding tape, it becomes easier to prepare at least one of the first tape member and the second tape member. When at least one of the first tape member and the second tape member includes the protective tape, the portion of the flat portion covered by the protective tape can be protected from surrounding members by the protective tape. When at least one of the first tape member and the second tape member includes the sound-absorbing tape, it is possible to suppress the generation of abnormal noise when the portion of the flat portion to which the sound-absorbing tape is attached collides with or rubs against surrounding members. When at least one of the first tape member and the second tape member includes the heat-resistant tape, it is possible to improve the heat resistance of the flat portion.

[0020] When at least one of the first tape member and the second tape member includes a metal tape, the metal tape can suppress the radiation of electromagnetic noise from the electric wire in the flat portion to the outside in the portion of the flat portion where the metal tape is attached. Also, in the same portion, the metal tape can suppress the intrusion of electromagnetic noise from the outside into the electric wire in the flat portion. Also, in the same portion, the metal tape can reflect radiant heat, suppressing the temperature rise of the electric wire in the flat portion.

[0021] When at least one of the first tape member and the second tape member includes a double-sided tape, one of the two adhesive layers of the double-sided tape can be attached to the flat portion. Furthermore, the flat portion can be easily fixed by attaching the other adhesive layer to the installation location of the flat portion. In other words, it is not necessary to prepare a separate part for fixing the flat portion. When at least one of the first tape member and the second tape member includes a hook-and-loop fastener, when the installation location of the flat portion has a surface to which the hook-and-loop fastener can be attached, the hook-and-loop fastener can be used to easily fix the flat portion to the installation location. When at least one of the first tape member and the second tape member includes a magnetic tape, when the installation location of the flat portion has a portion made of a material that is attracted to a magnet, the magnetic tape can be used to easily fix the flat portion by magnetic force.

[0022] [9] In the above [8], the electric wire binding tape may be a polyvinyl chloride tape. With this configuration, the electric wire binding tape used as a material for at least one of the first tape member and the second tape member can be more easily obtained.

[0023]

[10] In the above item [8], the protective tape may be a polypropylene tape. With this configuration, the protective tape used as a material for at least one of the first tape member and the second tape member can be easily obtained.

[0024]

[11] In the above [7], at least one of the first tape member and the second tape member may have the multiple tapes of the same type that are overlapped with each other in the thickness direction of the flat portion. According to this configuration, the thickness of at least one of the first tape member and the second tape member in the thickness direction of the flat portion can be easily increased by overlapping multiple tapes of the same type. Furthermore, the part of the flat portion that is covered by the part where multiple tapes of the same type are overlapped can be protected from surrounding members by the part where multiple tapes of the same type are overlapped. Furthermore, multiple tapes can be prepared more easily than when multiple types of tapes are overlapped.

[0025]

[12] In any of the above [1] to

[11] , each of the first tape member and the second tape member may have at least one tape, one of the first tape member and the second tape member may have the tape having a first width, the other of the first tape member and the second tape member may have the tape having a second width wider than the first width, and the tape having the first width and the tape having the second width may be overlapped on the flat portion from both sides in the thickness direction of the flat portion. According to this configuration, the tape having the second width protrudes in the width direction of the flat portion more than the tape having the first width. Therefore, the flat portion can be easily fixed by attaching the part of the tape having the second width that protrudes in the width direction of the flat portion more than the tape having the first width to the arrangement location of the flat portion. In other words, it is not necessary to prepare a separate part for fixing the flat portion.

[0026]

[13] In any of [7],

[11] and

[12] above, at least one of the first tape member and the second tape member has a tape having a first length and a tape having a second length longer than the first length, and the tape having the first length and the tape having the second length may have portions that are overlapped with each other in the thickness direction of the flat portion.

[0027] According to this configuration, in at least one of the first tape member and the second tape member, a portion where the tape having the first length and the tape having the second length are overlapped is thicker in the thickness direction of the flat portion than a portion where the two tapes are not overlapped. Therefore, by arranging a portion where the tape having the first length and the tape having the second length overlap in a portion of the flat portion of at least one of the first tape member and the second tape member where it is desired to increase the thickness in the thickness direction of the flat portion, it is possible to easily increase the thickness partially. For example, by arranging a portion where the tape having the first length and the tape having the second length overlap in a portion where it is desired to enhance the protection of the portion from the surrounding members, it is possible to easily enhance the protection of the portion. Furthermore, at least one of the first tape member and the second tape member can partially have the function of the tape having the first length in the length direction of the electric wire bundle. Furthermore, at least one of the first tape member and the second tape member can entirely or partially have the function of the tape having the second length in the length direction of the electric wire bundle.

[0028]

[14] In any of [7],

[11] ,

[12] and

[13] above, each of the multiple tapes of the first tape member is paired with the multiple tapes of the second tape member, the paired tapes are overlapped with each other on both sides in the thickness direction of the flat portion, sandwiching the flat portion, and are positioned at the same position in the extension direction of the electric wire bundle, at least one pair of the tapes among the multiple pairs of tapes have different widths, at least a portion of each of the multiple tapes of the first tape member overlaps with at least one of the multiple tapes of the first tape member in the thickness direction of the flat portion, and at least a portion of each of the multiple tapes of the second tape member overlaps with at least one of the multiple tapes of the second tape member in the thickness direction of the flat portion.

[0029] According to this configuration, when a pair of tapes having different widths are overlapped, the wider tape protrudes in the width direction of the flat portion more than the narrower tape. Therefore, the flat portion can be easily fixed by attaching the part of the wider tape that protrudes in the width direction of the flat portion more than the narrower tape to the routing location of the flat portion. In other words, there is no need to prepare a separate part for fixing the flat portion.

[0030] In addition, in each of the first tape member and the second tape member, each of the multiple tapes may be arranged so as to overlap with another tape in the thickness direction of the flat portion. Therefore, each of the multiple tapes can be easily arranged at a desired position in the length direction of the wire bundle according to the function of each of the multiple tapes. Also, by arranging the overlapping portion of the multiple tapes so as to overlap a portion of the flat portion where protection is desired to be strengthened, protection of that portion from surrounding members can be easily strengthened.

[0031]

[15] In any of the above [1] to

[14] , the bundle of electric wires may have two flat portions spaced apart in the extension direction of the bundle of electric wires, and a stacked portion located between the two flat portions in the extension direction of the bundle of electric wires, in which the electric wires are arranged in a different arrangement from the electric wires in the flat portions, the two flat portions and the stacked portion are sandwiched between the first tape member and the second tape member, and the multiple electric wires in the stacked portion may be arranged such that a thickness in a thickness direction of the flat portions is thicker in the stacked portion than in the flat portions and a width in a width direction of the flat portions is narrower in the stacked portion than in the flat portions.

[0032] According to this configuration, the plurality of electric wires in the stacked portion have fewer portions that contact the first tape member and the second tape member compared to the plurality of electric wires in the flat portion. Therefore, the stacked portion is easier to bend compared to the flat portion. Therefore, the stacked portion located between the two flat portions can be easily bent to route the wire harness. In other words, flexibility can be imparted to the wire harness.

[0033]

[16] In any of [1] to

[14] above, the flat portion may have a flat bending portion where the multiple electric wires are bent when viewed from a thickness direction of the flat portion, the multiple electric wires in the flat bending portion may be aligned in a row along the width direction of the flat portion and bent while maintaining the aligned row when viewed from the thickness direction of the flat portion, and the first tape member and the second tape member may sandwich the flat bending portion from both sides in the thickness direction of the flat portion and maintain the arrangement and bending shape of the multiple electric wires in the flat bending portion.

[0034] According to this configuration, the first tape member and the second tape member can keep the bent portion of the electric wire bundle flat. Therefore, even if the routing location of the flat portion is narrow and bent, the flat portion can be arranged at the routing location.

[0035]

[17] In any of the above [1] to

[14] , the electric wire bundle may have a single-layer bent portion in which the multiple electric wires are bent while being arranged flat at a position shifted from the flat portion in an extension direction of the electric wire bundle, and the multiple electric wires in the single-layer bent portion are arranged in a row along a direction perpendicular to the thickness direction of the single-layer bent portion when viewed from a thickness direction of the single-layer bent portion and are bent while maintaining the single-layer arrangement, and a third tape member and a fourth tape member are attached to each other while sandwiching the single-layer bent portion from both sides in the thickness direction of the single-layer bent portion, and the third tape member and the fourth tape member may maintain the arrangement and bent shape of the multiple electric wires in the single-layer bent portion.

[0036] According to this configuration, the single-layer bent portion where the electric wires are bent at a position away from the flat portion in the electric wire bundle can be easily maintained in a flat shape by the third tape member and the fourth tape member. Therefore, the wire harness can be easily arranged in a narrow space with the electric wire bundle in a bent state.

[0037]

[18] In any of the above [1] to

[14] , the electric wire bundle may have an overlapping bent portion at which the electric wire bundle is bent at a position shifted from the flat portion in an extension direction of the electric wire bundle, the plurality of electric wires at the overlapping bent portion are bent in an overlapping state so that the thickness of the overlapping bent portion in a thickness direction of the flat portion is thicker than that of the flat portion and the width of the overlapping bent portion in a width direction of the flat portion is narrower than that of the flat portion, and a first bend fixing tape member and a second bend fixing tape member are attached together with the overlapping bend portion sandwiched therebetween, and the first bend fixing tape member and the second bend fixing tape member may maintain the arrangement and bent shape of the plurality of electric wires at the overlapping bend portion.

[0038] According to this configuration, when the wiring harness has a curved portion, the overlapping bent portion can be shaped according to the shape of the curved portion. Furthermore, the first bend fixing tape member and the second bend fixing tape member can maintain the curved shape of the overlapping bend. Therefore, it is easier to install the wiring harness having the flat portion.

[0039]

[19] In any one of the above [1] to

[18] , the flat portion may be maintained in a straight line by the first tape member and the second tape member when viewed in the width direction of the flat portion. With this configuration, when the flat portion is routed in a straight line, the flat portion can be easily routed.

[0040]

[20] In any one of the above [1] to

[18] , the flat portion may be maintained in a curved shape by the first tape member and the second tape member when viewed in the width direction of the flat portion. With this configuration, the flat portion can be easily arranged when the routing location of the flat portion is curved.

[0041] [Details of the embodiment of the present disclosure] Specific examples of the wire harness of the present disclosure will be described below with reference to the drawings. Note that the present invention is not limited to these examples, but is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In addition, the accompanying drawings may show components enlarged for ease of understanding. In the accompanying drawings, the dimensional ratios of the components may differ from the actual ones or from those in other drawings.

[0042] First Embodiment Hereinafter, a first embodiment of the wire harness will be described. A wire harness 30 shown in FIG. 1 is mounted on a vehicle such as an automobile.

[0043] The wire harness 30 includes an electric wire bundle 40. The electric wire bundle 40 includes a plurality of electric wires 41. For example, the electric wire bundle 40 includes four electric wires 41. The four electric wires 41 are, for example, the same type of electric wires and have the same diameter. The electric wire bundle 40 is obtained by bundling a plurality of electric wires 41 together.

[0044] 2, each electric wire 41 has a conductive core wire 42 and an insulating coating 43 that surrounds the outer periphery of the core wire 42 and has insulating properties. Note that FIG. 2 is a cross-sectional view taken along line 2-2 in FIG.

[0045] The core wire 42 may be, for example, a stranded wire made by stranding a plurality of metal wires, a columnar conductor made of a single metal rod having a solid interior, or a tubular conductor having a hollow interior. Also, the core wire 42 may be, for example, a combination of at least two of the stranded wire, the columnar conductor, and the tubular conductor. The material of the core wire 42 may be, for example, a copper-based or aluminum-based metal material.

[0046] The insulating coating 43, for example, covers the outer periphery of the core wire 42 over the entire circumferential direction around the center line L1 of the electric wire 41. The insulating coating 43 is made of, for example, a resin material having insulating properties.

[0047] 1 and 2, a center line L1 of the electric wire 41 is illustrated by a dashed line. The center line L1 is a line passing through the center of the electric wire 41 in a cross section. A connector (not shown) is provided at the end of each electric wire 41. The connector has a connector housing and a connection terminal held inside the connector housing. The multiple electric wires 41 are electrically connected to different connection terminals.

[0048] The electric wire bundle 40 has a flat portion 45 where the electric wires 41 are arranged flat at least in a part in the extending direction of the electric wire bundle 40. For example, the electric wire bundle 40 has the flat portion 45 in a part of the electric wire bundle 40.

[0049] For example, in the flat portion 45, the four electric wires 41 are arranged in a row along a direction perpendicular to the extension direction of the electric wire bundle 40. The extension direction of the electric wire bundle 40 is hereinafter referred to as the extension direction X. The extension direction X is the length direction of the electric wire bundle 40 and is a direction along the center line L1 of the bundled electric wires 41. In the drawing, the extension direction X is indicated by a double-headed arrow.

[0050] In the flat portion 45, the electric wires 41 are arranged along a first direction Y that intersects perpendicularly with the extending direction X. A direction that intersects perpendicularly with the extending direction X and also intersects perpendicularly with the first direction Y is defined as a second direction Z. The first direction Y corresponds to the width direction of the flat portion 45. The second direction Z corresponds to the thickness direction of the flat portion 45. The cross-sectional shape of the flat portion 45 is a flat shape that is long in the first direction Y and thin in the second direction Z. Note that the "cross section" is a cross section cut by a plane perpendicular to the extending direction X. Also, the width of the flat portion 45 in the first direction Y is wider than the width of the flat portion 45 in the second direction Z. In the flat portion 45, the four electric wires 41 extend, for example, parallel to each other. Also, in the flat portion 45, the electric wires 41 adjacent to each other in the first direction Y are in contact with each other, for example.

[0051] In this specification, "plural electric wires are arranged flat" means that the plural electric wires are arranged so that the cross-sectional shape of the electric wire bundle is flat. That is, it means that the electric wires are arranged so that the cross-sectional shape of the electric wire bundle is long in a first direction perpendicular to the extension direction of the electric wire bundle and thin in a second direction perpendicular to the first direction. The width of the flat part in the first direction corresponds to the width of the widest part in the cross section of the flat part. Furthermore, the width of the flat part in the first direction and the width of the flat part in the second direction are different values, and the width of the flat part in the first direction is wider than the width of the flat part in the second direction. In addition, in this specification, "flat shape" means a state in which the plural electric wires are arranged flat.

[0052] The wire harness 30 includes a first tape member 50 and a second tape member 60. The first tape member 50 and the second tape member 60 are attached to each other from both sides in the thickness direction of the flat portion 45, sandwiching the flat portion 45 therebetween. The electric wires 41 in the flat portion 45 are integrally held by the first tape member 50 and the second tape member 60.

[0053] The first tape member 50 has, for example, a belt-like shape. The first tape member 50 has, for example, a belt-like first base material 51. In addition, the first tape member 50 has, for example, a first adhesive layer 52 laminated on one surface of the first base material 51.

[0054] The first tape member 50 is, for example, a protective tape. When the first tape member 50 is a protective tape, the first base material 51 is, for example, thicker than the base material of an electric wire bundling tape that is generally used to bundle electric wires. In this case, the first base material 51 is, for example, harder than the base material of the electric wire bundling tape. For example, the first base material 51 is made of a material having a higher Vickers hardness value than the base material of the electric wire bundling tape.

[0055] When the first tape member 50 is a protective tape, a polypropylene (PP) tape can be used as the first tape member 50. When the first tape member 50 is a PP tape, the first base material 51 is, for example, either a strip-shaped PP film or a woven fabric in which PP fibers are woven in a strip shape. When the first tape member 50 is a protective tape, any of acetate tape, polycarbonate tape, and polyethylene (PE) tape can also be used as the first tape member 50.

[0056] The second tape member 60 is, for example, strip-shaped. The second tape member 60 has, for example, a strip-shaped second base material 61. The second tape member 60 also has, for example, a second adhesive layer 62 laminated on one side of the second base material 61. The second tape member 60 is, for example, of the same type as the first tape member 50. In this embodiment, the first tape member 50 and the second tape member 60 are of the same type, so a detailed description of the second tape member 60 will be omitted.

[0057] The first tape member 50 and the second tape member 60 are attached to each other from both sides in the thickness direction of the flat portion 45, with the flat portion 45 sandwiched between them, so that the first pressure-sensitive adhesive layer 52 and the second pressure-sensitive adhesive layer 62 face each other with the flat portion 45 sandwiched therebetween. Each of the first tape member 50 and the second tape member 60 extends, for example, along the extending direction X. Furthermore, the flat portion 45 is maintained in a straight line by the first tape member 50 and the second tape member 60, for example, when viewed from the width direction of the flat portion 45.

[0058] The first tape member 50 and the second tape member 60 may be directly attached to each other on both sides in the width direction of the flat portion 45, for example. For example, the length of each of the first tape member 50 and the second tape member 60 in the width direction of the flat portion 45 is longer than that of the flat portion 45. The first tape member 50 and the second tape member 60 may have a first attachment end 53 and a second attachment end 63 that are directly attached to each other on both sides in the width direction of the flat portion 45, respectively. The first tape member 50 has the first attachment end 53 in the end region of both ends of the first tape member 50 in the width direction, for example. The second tape member 60 has the second attachment end 63 in the end region of both ends of the second tape member 60 in the width direction, for example. In the wire harness 30, the flat portion 45 is located between two sets of the first attachment end 53 and the second attachment end 63 that are attached to each other. Each of the first attachment end portion 53 and the second attachment end portion 63 extends along an extension direction X.

[0059] In addition, at least one of the first tape member 50 and the second tape member 60 may be attached to at least a portion of the outer peripheral surface of at least one of the electric wires 41 located between the first tape member 50 and the second tape member 60.

[0060] For example, the first tape member 50 is attached to a part of the outer circumferential surface of each of the four electric wires 41 located between the first tape member 50 and the second tape member 60. That is, in the first tape member 50, the first adhesive layer 52 is in contact with a part of the outer circumferential surface of each of the four electric wires 41 located between the first tape member 50 and the second tape member 60. And, for example, in the first tape member 50, the first adhesive layer 52 is in close contact with a part of the outer circumferential surface of each of the four electric wires 41 located between the first tape member 50 and the second tape member 60.

[0061] For example, the second tape member 60 is attached to a part of the outer circumferential surface of each of the four electric wires 41 located between the first tape member 50 and the second tape member 60. That is, the second tape member 60 has the second adhesive layer 62 in contact with a part of the outer circumferential surface of each of the four electric wires 41 located between the first tape member 50 and the second tape member 60. And, for example, the second tape member 60 has the second adhesive layer 62 in close contact with a part of the outer circumferential surface of each of the four electric wires 41 located between the first tape member 50 and the second tape member 60.

[0062] In addition, at least one of the first tape member 50 and the second tape member 60 may have an arc attachment portion 54, 64 that is attached to the outer peripheral surface of at least one of the electric wires 41 located between the first tape member 50 and the second tape member 60 and forms an arc shape along the outer peripheral surface.

[0063] For example, the first tape member 50 has two first arc-shaped attachment portions 54 that are attached to the outer peripheral surfaces of two electric wires 41 that are aligned at both ends in the flat portion 45 among the electric wires 41 located between the first tape member 50 and the second tape member 60 and that form arc shapes along the outer peripheral surfaces. The first adhesive layer 52 in the two first arc-shaped attachment portions 54 is in surface contact with parts of the outer peripheral surfaces of the two electric wires 41 that are aligned at both ends in the flat portion 45. And, for example, the first adhesive layer 52 in the two first arc-shaped attachment portions 54 is in close contact with parts of the outer peripheral surfaces of the two electric wires 41 that are aligned at both ends in the flat portion 45.

[0064] For example, the second tape member 60 has two second arc-shaped attachment portions 64 that are attached to the outer peripheral surfaces of two electric wires 41 that are aligned at both ends in the flat portion 45 among the electric wires 41 located between the first tape member 50 and the second tape member 60 and form arc shapes along the outer peripheral surfaces. The second adhesive layer 62 in the two second arc-shaped attachment portions 64 is in surface contact with parts of the outer peripheral surfaces of the two electric wires 41 that are aligned at both ends in the flat portion 45. And, for example, the second adhesive layer 62 in the two second arc-shaped attachment portions 64 is in close contact with parts of the outer peripheral surfaces of the two electric wires 41 that are aligned at both ends in the flat portion 45.

[0065] The operation of this embodiment will be described. The first tape member 50 and the second tape member 60 restrict relative movement between the electric wires 41 in the flat portion 45, and restrict movement of the electric wires 41 relative to the first tape member 50 and the second tape member 60. In other words, between the first tape member 50 and the second tape member 60, movement of the electric wires 41 that would increase the thickness of the flat portion 45 is restricted.

[0066] The effects of this embodiment will be described. (1-1) By bonding the first tape member 50 and the second tape member 60 together, the flat portion 45 sandwiched between the first tape member 50 and the second tape member 60 can be maintained in a state in which the multiple electric wires 41 are arranged flat. Therefore, the first tape member 50 and the second tape member 60 can easily maintain the multiple electric wires 41 in the flat portion 45 in a flat state.

[0067] (1-2) Each of the first tape member 50 and the second tape member 60 has a belt shape and extends along the extending direction X. According to this configuration, the multiple electric wires 41 in the flat portion 45 can be easily maintained flat over the range in which the first tape member 50 and the second tape member 60 are bonded together along the extending direction X.

[0068] (1-3) The first tape member 50 and the second tape member 60 are directly attached to each other on both sides in the width direction of the flat portion 45. This configuration suppresses the second tape member 60 from moving relative to the first tape member 50. Therefore, the first tape member 50 and the second tape member 60 make it easier to maintain the plurality of electric wires 41 in the flat portion 45 in a flat shape. In addition, the first tape member 50 and the second tape member 60 can surround the entire outer periphery of the flat portion 45. Therefore, when the wire harness 30 is routed, the first tape member 50 and the second tape member 60 can suppress the peripheral members and the like from directly contacting the flat portion 45. In other words, the wire harness 30 can be protected.

[0069] (1-4) Each of the first tape member 50 and the second tape member 60 is attached to at least a part of the outer circumferential surface of each electric wire 41 located between the first tape member 50 and the second tape member 60. According to this configuration, it is easier to maintain the plurality of electric wires 41 in the flat portion 45 in a flat state.

[0070] (1-5) The first tape member 50 has a first arc-shaped attachment portion 54 that is attached to the outer peripheral surfaces of two electric wires 41 located at both ends in the width direction of the flat portion 45 among the electric wires 41 located between the first tape member 50 and the second tape member 60 and that forms an arc-shaped attachment portion 54 along the outer peripheral surface. The second tape member 60 has a second arc-shaped attachment portion 64 that is attached to the outer peripheral surfaces of two electric wires 41 located at both ends in the width direction of the flat portion 45 among the electric wires 41 located between the first tape member 50 and the second tape member 60 and that forms an arc-shaped attachment portion 64 along the outer peripheral surface. This configuration makes it easier to maintain the multiple electric wires 41 in the flat portion 45 in a flat state.

[0071] (1-6) Each of the first tape member 50 and the second tape member 60 is a protective tape. The first tape member 50 has a strip-shaped first base material 51 and a first adhesive layer 52 laminated on one side of the first base material 51. The second tape member 60 has a strip-shaped second base material 61 and a second adhesive layer 62 laminated on one side of the second base material 61. When each of the first tape member 50 and the second tape member 60 is a protective tape, each of the first base material 51 and the second base material 61 is thicker than the base material of the electric wire bundling tape used to bundle electric wires. Therefore, the protective tape is less likely to tear than the electric wire bundling tape. Therefore, by using the protective tape as the first tape member 50 and the second tape member 60, the part of the flat part 45 covered by the first tape member 50 and the second tape member 60 can be protected from the surrounding members by the first tape member 50 and the second tape member 60.

[0072] (1-7) The protective tape used as the first tape member 50 and the second tape member 60 is a polypropylene tape. According to this configuration, the protective tape used as the material for the first tape member 50 and the second tape member 60 is easily available.

[0073] (1-8) The first tape member 50 and the second tape member 60 are of the same type. With this configuration, preparation of the first tape member 50 and the second tape member 60 is easier than when the first tape member 50 and the second tape member 60 are of different types. Also, the first tape member 50 may be disposed on either side of the flat portion 45 in the thickness direction. Therefore, there is no risk of misattaching the first tape member 50 and the second tape member 60 to the flat portion 45, and the productivity of the wire harness 30 can be improved.

[0074] (1-9) When viewed in the width direction of the flat portion 45, the flat portion 45 is maintained in a straight line by the first tape member 50 and the second tape member 60. According to this configuration, when the routing location of the flat portion 45 is linear, the flat portion 45 can be easily routed.

[0075] (1-10) The plurality of electric wires 41 in the flat portion 45 are maintained flat by attaching the first tape member 50 and the second tape member 60 to both sides of the flat portion 45 in the thickness direction of the flat portion 45. This prevents the plurality of electric wires 41 in the flat portion 45 from coming apart. This makes it easier to arrange the wire harness 30.

[0076] (1-11) In order to maintain the plurality of electric wires 41 in the flat portion 45 in a flat state, a conventional resin molded electric wire flattening member is not used. Instead, the plurality of electric wires 41 in the flat portion 45 are maintained in a flat state by a first tape member 50 and a second tape member 60 each having a belt shape. Therefore, compared to the case where a conventional electric wire flattening member is used, the flat portion 45 and the portion of the wire harness 30 around the flat portion 45 can be made thinner.

[0077] Furthermore, the first tape member 50 and the second tape member 60 can easily change their length in the extending direction X and their width in the first direction Y, compared to conventional wire-flattening members that are resin molded products. Therefore, a user of the first tape member 50 and the second tape member 60 can finely adjust the length and contour of each of the first tape member 50 and the second tape member 60 at any location, such as the manufacturing site of the wire harness 30.

[0078] In addition, conventional resin molded wire flattening members are generally formed using a mold. The mold for forming the wire flattening member has a shape according to the diameter and number of the wires included in the wire harness. Therefore, when the diameter and number of the wires included in the wire harness are changed, the shape of the mold for forming the wire flattening member is also changed. This causes a problem of increased manufacturing costs. In contrast, each of the first tape member 50 and the second tape member 60 is formed from a tape such as a protective tape. Therefore, even if the diameter and number of the wires 41 included in the wire harness 30 are changed, it is not necessary to newly manufacture a mold, so that an increase in manufacturing costs can be suppressed. In addition, commercially available tapes can be used as each of the first tape member 50 and the second tape member 60. Therefore, even if the diameter and number of the wires 41 included in the wire harness 30 are changed, tapes to be used as each of the first tape member 50 and the second tape member 60 can be easily prepared.

[0079] <Second embodiment> Hereinafter, a second embodiment of the wire harness will be described. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description of the components will be omitted in part or in whole.

[0080] 3 and 4, a wire harness 30A of the second embodiment includes a wire bundle 40 having a flat portion 45, a first tape member 50, and a second tape member 60. Note that Fig. 4 is a cross-sectional view taken along line 4-4 in Fig. 3.

[0081] The first tape member 50 has four first arc-shaped attachment portions 54 attached to the outer circumferential surfaces of the four electric wires 41 positioned between the first tape member 50 and the second tape member 60. The four first arc-shaped attachment portions 54 are lined up along the first direction Y, i.e., along the width direction of the flat portion 45, between the two first attachment ends 53. The four first arc-shaped attachment portions 54 are also lined up continuously along the width direction of the flat portion 45.

[0082] The first adhesive layer 52 in the four first arc-shaped attachment portions 54 is in surface contact with a part of the outer circumferential surface of the four electric wires 41 in the flat portion 45. For example, the first adhesive layer 52 in the four first arc-shaped attachment portions 54 is in close contact with a part of the outer circumferential surface of the four electric wires 41 in the flat portion 45. Each of the first arc-shaped attachment portions 54 has an arc shape that follows the outer circumferential surface of the electric wire 41. Each of the first arc-shaped attachment portions 54 extends in the extension direction X.

[0083] Similarly, the second tape member 60 also has four second arc-shaped attachment portions 64. Note that the four second arc-shaped attachment portions 64 have the same configuration as the four first arc-shaped attachment portions 54, and therefore a description of the four second arc-shaped attachment portions 64 will be omitted.

[0084] According to the second embodiment, the same effect as the first embodiment is achieved. Furthermore, in the flat portion 45, the first arcuate attachment portion 54 and the second arcuate attachment portion 64 are attached to each of the electric wires 41. Therefore, in the flat portion 45, the relative movement between the electric wires 41 is suppressed.

[0085] According to the second embodiment, in addition to the same effects as those of the first embodiment, the following effects are achieved. (2-1) The first tape member 50 and the second tape member 60 have arcuate attachment portions 54, 64 that are attached to the outer circumferential surface of each electric wire 41 located between the first tape member 50 and the second tape member 60 and form an arcuate shape along the outer circumferential surface. This configuration makes it easier to maintain the plurality of electric wires 41 in the flat portion 45 in a flat state.

[0086] <Third embodiment> Hereinafter, a third embodiment of the wire harness will be described. In the third embodiment, the same components as or corresponding components to those in the first or second embodiment are denoted by the same reference numerals, and the description of the components will be omitted in part or in whole.

[0087] 5 and 6, a wire harness 30B of the third embodiment includes a wire bundle 40 having a flat portion 45B, a first tape member 50, and a second tape member 60. Note that Fig. 6 is a cross-sectional view taken along line 6-6 in Fig. 5.

[0088] For example, the electric wire bundle 40 has a flat portion 45B in which the electric wires 41 are arranged flat in a part of the extending direction of the electric wire bundle 40. In the flat portion 45B, the electric wires 41 are arranged along a first direction Y that perpendicularly intersects with the extending direction X. The cross-sectional shape of the flat portion 45B is a flat shape that is long in the first direction Y and thin in the second direction Z. In addition, in the flat portion 45B, the four electric wires 41 extend, for example, parallel to each other. In addition, in the flat portion 45B In the embodiment, the electric wires 41 adjacent to each other in the first direction Y are arranged in the first direction Y, i.e., in the flat portion. 45B are spaced apart in the width direction.

[0089] The first tape member 50 and the second tape member 60 are directly attached to each other between the adjacent electric wires 41 in the flat portion 45B. 45B The electric wires 41 each have a first inter-electrical wire adhesion portion 55 and a second inter-electrical wire adhesion portion 65 that are directly attached to each other between adjacent electric wires 41 in the width direction. Each of the first inter-electrical wire adhesion portion 55 and the second inter-electrical wire adhesion portion 65 extends along the extending direction X.

[0090] In the flat portion 45B of the wire harness 30B, the first inter-electrical wire adhesion portion 55 and the second inter-electrical wire adhesion portion 65, which are respectively attached to each other, are located between the four electric wires 41. The first tape member 50 and the second tape member 60 have the first inter-electrical wire adhesion portion 55 and the second inter-electrical wire adhesion portion 65, so that the plurality of electric wires 41 are fixed to the flat portion 45B. 45B The electrodes are kept apart in the width direction.

[0091] The first tape member 50 has two first attachment ends 53 and four first arcuate attachment portions 54. In the first tape member 50, the first arcuate attachment portions 54 are located on both sides of the first inter-electric-wire attachment portion 55 in the width direction of the flat portion 45B. Similarly, the second tape member 60 has two second attachment ends 63 and four second arcuate attachment portions 64. In the second tape member 60, the second arcuate attachment portions 64 are located on both sides of the second inter-electric-wire attachment portion 65 in the width direction of the flat portion 45B. In the flat portion 45B, the entire outer periphery of each electric wire 41 is surrounded by the first tape member 50 and the second tape member 60.

[0092] According to the third embodiment, the same effects as those of the first and second embodiments are obtained. Furthermore, since the first tape member 50 and the second tape member 60 have the first inter-electric-wire adhesion portion 55 and the second inter-electric-wire adhesion portion 65, the electric wires 41 adjacent to each other in the width direction of the flat portion 45B can be maintained apart from each other in the width direction of the flat portion 45B.

[0093] Furthermore, because the first tape member 50 and the second tape member 60 have the first inter-electric wire adhesion portion 55 and the second inter-electric wire adhesion portion 65, the outer circumferential surface of each electric wire 41 in the flat portion 45B is entirely covered by the first arc-shaped adhesion portion 54 and the second arc-shaped adhesion portion 64. Therefore, in the flat portion 45B, air layers are less likely to form between the outer circumferential surface of each electric wire 41 and the first tape member 50, and between the outer circumferential surface of each electric wire 41 and the second tape member 60.

[0094] According to the third embodiment, in addition to the same effects as those of the first embodiment and the effect (2-1) of the second embodiment, the following effect is achieved. (3-1) The first tape member 50 and the second tape member 60 are directly attached to each other between adjacent electric wires 41 in the flat portion 45B. According to this configuration, in the flat portion 45B, the multiple electric wires 41 are maintained in a state separated in the width direction of the flat portion 45B by the first tape member 50 and the second tape member 60. Therefore, the surface area of ​​the portions where the first tape member 50 and the second tape member 60 cover the electric wires 41 can be made larger than when adjacent electric wires 41 in the width direction of the flat portion 45B are in contact with each other. Therefore, the heat dissipation in the flat portion 45B can be improved.

[0095] Furthermore, in the flat portion 45B, if the electric wires 41 adjacent to each other in the width direction of the flat portion 45B are maintained apart in the width direction of the flat portion 45B, frictional force is unlikely to occur between the electric wires 41 when the flat portion 45B is bent. This makes it easier to bend the flat portion 45B. Therefore, if each of the first tape member 50 and the second tape member 60 is more flexible than the electric wires 41, the flexibility of the flat portion 45B can be improved.

[0096] <Fourth embodiment> Hereinafter, a fourth embodiment of the wire harness will be described. In the fourth embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description of the components will be omitted in part or in whole.

[0097] A wire harness 30C according to the fourth embodiment shown in Fig. 7 to Fig. 9 includes a wire bundle 40C, a first tape member 50, and a second tape member 60. Fig. 8 is a cross-sectional view taken along line 8-8 in Fig. 7. Fig. 9 is a cross-sectional view taken along line 9-9 in Fig. 7.

[0098] The electric wire bundle 40C has, for example, eight electric wires 41. The eight electric wires 41 are, for example, the same type of electric wire and have the same diameter. The electric wire bundle 40C has two flat portions 45a and 45b. In each of the flat portions 45a and 45b, eight electric wires 41 are arranged in a row along the first direction Y, similar to the flat portion 45 of the first embodiment. The flat portion 45a and the flat portion 45b are separated from each other in the extending direction X.

[0099] Also, wire bundles 40C has a stacked portion 46 located between the two flat portions 45a, 45b in the extending direction X. In the stacked portion 46, the electric wires 41 are arranged in a manner different from that of the electric wires 41 in each of the flat portions 45a, 45b. The electric wires 41 in the stacked portion 46 are arranged such that the thickness of the stacked portion 46 in the thickness direction of the flat portions 45a, 45b is greater than that of each of the flat portions 45a, 45b. Moreover, the electric wires 41 in the stacked portion 46 are arranged such that the thickness of the stacked portion 46 in the thickness direction of the flat portions 45a, 45b is greater than that of each of the flat portions 45a, 45b. 45a, 45b The stacked portion 46 is arranged such that the width in the width direction of the flat portions 45a, 45b is narrower than the width of the flat portions 45a, 45b. Therefore, the thickness T1 of the stacked portion 46 in the thickness direction of the flat portions 45a, 45b, i.e., in the second direction Z, is thicker than the thickness T2 of the flat portion 45a in the second direction Z. Furthermore, the width W1 of the stacked portion 46 in the width direction of the flat portions 45a, 45b, i.e., in the first direction Y, is narrower than the width W2 of the flat portion 45a in the first direction Y. Furthermore, the thickness T1 of the stacked portion 46 in the second direction Z is thicker than the thickness of the flat portion 45b in the second direction Z. Furthermore, the width W1 of the stacked portion 46 in the first direction Y is narrower than the width of the flat portion 45b in the first direction Y.

[0100] Note that the thickness T2 of the flat portion 45a in the second direction Z and the thickness of the flat portion 45b in the second direction Z are, for example, the same. Also, the width W2 of the flat portion 45a in the first direction Y and the width of the flat portion 45b in the second direction Z are, for example, the same. However, the thickness T2 of the flat portion 45a in the second direction Z and the thickness of the flat portion 45b in the second direction Z may be different. Also, the width W2 of the flat portion 45a in the first direction Y and the width of the flat portion 45b in the second direction Z may be different.

[0101] In each of the flat portions 45a and 45b, eight electric wires 41 are arranged in a row, i.e., in one layer, along the first direction Y. In contrast, in the stacked portion 46, the eight electric wires 41 are arranged stacked in the second direction Z. For example, in a part of the stacked portion 46, there are three rows of electric wires 41 arranged along the first direction Y. Also, in a part of the stacked portion 46, three layers of electric wires 41 arranged along the first direction Y are stacked in the second direction Z.

[0102] The two flat portions 45a, 45b and the stacked portion 46 are sandwiched between the first tape member 50 and the second tape member 60. The first tape member 50 and the second tape member 60 are attached to each other from both sides in the thickness direction of the flat portions 45a, 45b, with the flat portions 45a, 45b and the stacked portion 46 sandwiched between them.

[0103] According to the fourth embodiment, the same effects as those of the first embodiment can be achieved. Furthermore, the portions of the plurality of electric wires 41 in the stacked portion 46 that come into contact with the first tape member 50 and the second tape member 60 can be reduced compared to the plurality of electric wires 41 in the flat portions 45a, 45b.

[0104] According to the fourth embodiment, in addition to the same effects as those of the first embodiment, the following effects are achieved. (4-1) The electric wire bundle 40C has two flat portions 45a, 45b spaced apart in the extending direction X, and a stacked portion 46 located between the two flat portions 45a, 45b in the extending direction X and in which the electric wires 41 are arranged in a manner different from that of the electric wires 41 in the flat portions 45a, 45b. The two flat portions 45a, 45b and the stacked portion 46 are sandwiched between the first tape member 50 and the second tape member 60. The plurality of electric wires 41 in the stacked portion 46 are arranged such that the thickness of the flat portions 45a, 45b in the thickness direction is thicker in the stacked portion 46 than in the flat portions 45a, 45b, and 45a, 45b The stacked portions 46 are arranged so that the width in the width direction is narrower than the flat portions 45a, 45b.

[0105] According to this configuration, the plurality of electric wires 41 in the stacked portion 46 has fewer portions that contact the first tape member 50 and the second tape member 60 compared to the plurality of electric wires 41 in the flat portions 45a, 45b. Therefore, the stacked portion 46 is easier to bend than the flat portions 45a, 45b. Therefore, the stacked portion 46 located between the two flat portions 45a, 45b can be easily bent to route the wire harness 30C. In other words, flexibility can be imparted to the wire harness 30C.

[0106] <Fifth embodiment> Hereinafter, a fifth embodiment of the wire harness will be described. In the fifth embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description of the components will be omitted in part or in whole.

[0107] 10 and 11, a wire harness 30D according to the fifth embodiment includes a wire bundle 40D, a first tape member 50, and a second tape member 60. Note that FIG. 11 is a cross-sectional view taken along line 11-11 in FIG.

[0108] The electric wire bundle 40D has, for example, twelve electric wires 41. The twelve electric wires 41 are, for example, of the same type and have the same diameter. The electric wire bundle 40D has a flat portion 45D where the electric wires 41 are arranged flat in a part in the extending direction X. The flat portion 45D has a flat bent portion 47 where the electric wires 41 are bent when viewed in the thickness direction of the flat portion 45D.

[0109] The electric wires 41 in the flat bent portion 47 are aligned in a row along the width direction of the flat portion 45D, and are bent while maintaining the aligned arrangement when viewed from the thickness direction of the flat portion 45D. The electric wires 41 in the flat bent portion 47 are aligned such that the length of the electric wires 41 in the flat bent portion 47 gradually increases from the electric wire 41 located at one end in the width direction of the flat bent portion 47 to the electric wire 41 located at the other end. For example, the twelve electric wires 41 in the flat bent portion 47 are curved in a concentric arc shape when viewed from the thickness direction of the flat portion 45D. The radius of curvature of the electric wires 41 in the flat bent portion 47 gradually increases from the electric wire 41 located at one end in the width direction of the flat bent portion 47 to the electric wire 41 located at the other end. The twelve electric wires 41 in the flat bent portion 47 are all curved with different curvatures. In addition, in the flat bent portion 47, the electric wires 41 adjacent to each other in the width direction of the flat portion 45D are in contact with each other, for example.

[0110] The first tape member 50 and the second tape member 60 sandwich the flat bent portion 47 from both sides in the thickness direction of the flat portion 45D. Furthermore, the first tape member 50 and the second tape member 60 maintain the arrangement and bending shape of the multiple electric wires 41 in the flat bent portion 47. For example, the first tape member 50 and the second tape member 60 maintain the arrangement and bending shape of the multiple electric wires 41 in the flat bent portion 47 by the adhesive forces of the first adhesive layer 52 and the second adhesive layer 62, and the first base material 51 and the second base material 61.

[0111] According to the fifth embodiment, the same effects as those of the first embodiment can be achieved. Furthermore, the bent portion of the electric wires 41 in the electric wire bundle 40D can be maintained in a bent shape by the first tape member 50 and the second tape member 60, and can also be maintained in a flat shape.

[0112] According to the fifth embodiment, in addition to the same effects as those of the first embodiment, the following effects are achieved. (5-1) The flat portion 45D has a flat bent portion 47 at which the multiple electric wires 41 are bent when viewed in the thickness direction of the flat portion 45D. The multiple electric wires 41 in the flat bent portion 47 are aligned in a row along the width direction of the flat portion 45D, and are bent while maintaining the aligned arrangement when viewed in the thickness direction of the flat portion 45. The first tape member 50 and the second tape member 60 sandwich the flat bent portion 47 from both sides in the thickness direction of the flat portion 45D, and maintain the arrangement and bent shape of the multiple electric wires 41 in the flat bent portion 47.

[0113] According to this configuration, the portion where the plurality of electric wires 41 in the electric wire bundle 40D are bent can also be kept flat by the first tape member 50 and the second tape member 60. Therefore, even if the routing location of the flat portion 45D is narrow and bent, the flat portion 45D can be arranged in the routing location.

[0114] Sixth Embodiment Hereinafter, a sixth embodiment of the wire harness will be described. In the sixth embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description of the components will be omitted in part or in whole.

[0115] A wire harness 30E according to the sixth embodiment shown in Fig. 12 and Fig. 13 has an electric wire bundle 40E. Fig. 13 is a cross-sectional view taken along line 13-13 in Fig. 12. The electric wire bundle 40E has, for example, twelve electric wires 41. The twelve electric wires 41 are, for example, of the same type and have the same diameter.

[0116] The electric wire bundle 40E has, for example, two flat portions 45E in which a plurality of electric wires 41 are arranged flat in a part in the extending direction X. The electric wire bundle 40E may have only one flat portion 45E. The flat portion 45E has a different number of electric wires 41, but has a similar configuration to the flat portion 45 of the first embodiment. The two flat portions 45E are located at two positions apart in the extending direction X of the electric wire bundle 40E. The thicknesses of the two flat portions 45E in the second direction Z are, for example, the same. The widths of the two flat portions 45E in the first direction Y are, for example, the same.

[0117] Each flat portion 45E is sandwiched from both sides in the thickness direction of the flat portion 45E by a first tape member 50 and a second tape member 60. That is, the wire harness 30E includes two pairs of a first tape member 50 and a second tape member 60.

[0118] The electric wire bundle 40E has an overlapping bent portion 48 where the electric wire bundle 40E is bent at a position shifted from the flat portion 45E in the extending direction X. The electric wire bundle 40E has the overlapping bent portion 48 between two flat portions 45E in the extending direction X, for example.

[0119] In the overlapping bent portion 48, the electric wires 41 are arranged in a different manner from the electric wires 41 in the flat portion 45E. In the overlapping bent portion 48, the electric wires 41 are stacked in the thickness direction of the flat portion 45E. The electric wires 41 in the overlapping bent portion 48 are bent in an overlapping state so that the thickness in the thickness direction of the flat portion 45E is thicker in the overlapping bent portion 48 than in the flat portion 45E. Moreover, the electric wires 41 in the overlapping bent portion 48 are bent in an overlapping state so that the width in the width direction of the flat portion 45E is narrower in the overlapping bent portion 48 than in the flat portion 45E. Therefore, the thickness T3 of the overlapping bent portion 48 in the thickness direction of the flat portion 45E, i.e., in the second direction Z, is thicker than the thickness of the flat portion 45E in the second direction Z. Furthermore, the width W3 of the overlapping bent portion 48 in the width direction of the flat portion 45E, i.e., in the first direction Y, is narrower than the width of the flat portion 45E in the first direction Y. The thickness T3 and width W3 of the lapped bent portion 48 are compared with the thickness and width of the flat portion 45E located closest to the lapped bent portion 48 in the electric wire bundle 40E.

[0120] The wire harness 30E includes a first bend fixing tape member 70 and a second bend fixing tape member 80 that are bonded together with the overlapping bent portion 48 sandwiched therebetween. The first bend fixing tape member 70 has a sheet-like first base material 71 and a first adhesive layer 72 laminated on one side of the first base material 71. The second bend fixing tape member 80 has a sheet-like second base material 81 and a second adhesive layer 82 laminated on one side of the second base material 81. The first bend fixing tape member 70 and the second bend fixing tape member 80 are bonded together with the overlapping bend portion 48 sandwiched therebetween, with the first adhesive layer 72 and the second adhesive layer 82 facing each other.

[0121] The first bend fixing tape member 70 and the second bend fixing tape member 80 maintain the arrangement and bent shape of the multiple electric wires 41 in the overlapping bent portion 48. For example, the first bend fixing tape member 70 and the second bend fixing tape member 80 maintain the arrangement and bent shape of the multiple electric wires 41 in the overlapping bent portion 48 by the adhesive forces of the first adhesive layer 72 and the second adhesive layer 82, and the first base material 71 and the second base material 81.

[0122] According to the sixth embodiment, the same effects as those of the first embodiment can be achieved. Furthermore, in the electric wire bundle 40E having the flat portion 45E, the portion where the electric wires 41 are bent, i.e., the overlapping bent portion 48, can be maintained in a bent shape by the first bend fixing tape member 70 and the second bend fixing tape member 80.

[0123] According to the sixth embodiment, in addition to the same effects as those of the first embodiment, the following effects are achieved. (6-1) The electric wire bundle 40E has an overlapping bent portion 48 at a position shifted from the flat portion 45E in the extending direction X at which the electric wire bundle 40E is bent. The electric wires 41 in the overlapping bent portion 48 are bent in an overlapping state so that the thickness in the thickness direction of the flat portion 45E is thicker at the overlapping bent portion 48 than at the flat portion 45E. The electric wires 41 in the overlapping bent portion 48 are bent in an overlapping state so that the width in the width direction of the flat portion 45E is narrower at the overlapping bent portion 48 than at the flat portion 45E. The wire harness 30E includes a first bend fixing tape member 70 and a second bend fixing tape member 80 that are bonded together with the overlapping bend portion 48 sandwiched therebetween. The first bend fixing tape member 70 and the second bend fixing tape member 80 maintain the arrangement and bent shape of the electric wires 41 in the overlapping bend portion 48.

[0124] According to this configuration, when the wiring harness 30E has a curved portion at the wiring location, the overlapping bent portion 48 can be shaped according to the shape of the curved portion. Furthermore, the first bend fixing tape member 70 and the second bend fixing tape member 80 can maintain the curved shape of the overlapping bend portion 48. Therefore, the wiring harness 30E having the flat portion 45E can be more easily performed.

[0125] Seventh embodiment Hereinafter, a seventh embodiment of the wire harness will be described. In the seventh embodiment, the same components as or corresponding components to the above-described embodiments are denoted by the same reference numerals, and the description of the components will be omitted in part or in whole.

[0126] 14 and 15, a wire harness 30K according to the seventh embodiment includes a wire bundle 40 having a flat portion 45, a first tape member 50K, and a second tape member 60K. Note that FIG. 15 is a cross-sectional view taken along line 15-15 in FIG.

[0127] The first tape member 50K and the second tape member 60K are attached to each other from both sides in the thickness direction of the flat portion 45, sandwiching the flat portion 45. The electric wires 41 in the flat portion 45 are integrally held by the first tape member 50K and the second tape member 60K.

[0128] The first tape member 50K has, for example, a band shape extending along the extension direction X as a whole. The first tape member 50K has a plurality of tapes 100 overlapped with each other in the thickness direction of the flat portion 45, i.e., the second direction Z. For example, the first tape member 50K has three first tapes 101a, 101b, and 101c as the plurality of tapes 100. The number of tapes 100 included in the first tape member 50K is not limited to three, and may be two or four or more. Incidentally, the first tape member 50 in each of the first to sixth embodiments is constituted by one tape 100.

[0129] The first tape 101a is directly attached to the flat portion 45. The first tape 101a may have an arc attachment portion 54. The first tape 101b is directly overlapped on the first tape 101a in the second direction Z. The first tape 101c is directly overlapped on the first tape 101b in the second direction Z. The first tapes 101a, 101b, and 101c, for example, have the same width in the first direction Y. The first tapes 101a, 101b, and 101c, for example, have the same length in the extension direction X. Furthermore, the first tapes 101a, 101b, and 101c, for example, are located at the same position in the extension direction X.

[0130] The second tape member 60K has, for example, a band shape extending along the extension direction X as a whole. The second tape member 60K has a plurality of tapes 100 overlapped with each other in the second direction Z. For example, the second tape member 60K has three second tapes 102a, 102b, and 102c as the plurality of tapes 100. The number of tapes 100 included in the second tape member 60K is not limited to three, and may be two or four or more. The number of tapes 100 included in the second tape member 60K may be different from the number of tapes 100 included in the first tape member 50K. Incidentally, the second tape member 60 in each of the first to sixth embodiments is constituted by one tape 100.

[0131] The second tape 102a is attached directly to the flat portion 45 at a position where the flat portion 45 is sandwiched between the second tape 102a and the first tape 101a. The second tape 102a may have an arc attachment portion 64. The second tape 102b is directly overlapped on the second tape 102a in the second direction Z. The second tape 102c is directly overlapped on the second tape 102b in the second direction Z. The second tapes 102a, 102b, and 102c, for example, have the same width in the first direction Y. For example, the width of each of the second tapes 102a, 102b, and 102c in the first direction Y is equal to the width of each of the first tapes 101a, 101b, and 101c in the first direction Y. The second tapes 102a, 102b, and 102c, for example, have the same length in the extension direction X. For example, the length of each of the second tapes 102a, 102b, and 102c in the extending direction X is equal to the length of each of the first tapes 101a, 101b, and 101c in the extending direction X. Furthermore, the second tapes 102a, 102b, and 102c, for example, are at the same positions as each other in the extending direction X. For example, the positions of each of the second tapes 102a, 102b, and 102c in the extending direction X are the same as the positions of each of the first tapes 101a, 101b, and 101c in the extending direction X.

[0132] Each of the tapes 100 has, for example, a belt shape extending along the extension direction X. The first tape 101a has, for example, a first base material 51a and a first adhesive layer 52a laminated on one side of the first base material 51a. The first tape 101b has, for example, a first base material 51b and a first adhesive layer 52b laminated on one side of the first base material 51b. The first tape 101c has, for example, a first base material 51c and a first adhesive layer 52c laminated on one side of the first base material 51c. Each of the first base materials 51a, 51b, and 51c has, for example, a belt shape.

[0133] The second tape 102a has, for example, a second base material 61a and a second adhesive layer 62a laminated on one side of the second base material 61a. The second tape 102b has, for example, a second base material 61b and a second adhesive layer 62b laminated on one side of the second base material 61b. The second tape 102c has, for example, a second base material 61c and a second adhesive layer 62c laminated on one side of the second base material 61c. Each of the second base materials 61a, 61b, and 61c has, for example, a strip shape.

[0134] Each of the first tape 101a and the second tape 102a is, for example, a metal tape. When the first tape 101a and the second tape 102a are metal tapes, each of the first base material 51a and the second base material 61a is made of metal. For example, each of the first base material 51a and the second base material 61a is a strip of aluminum foil.

[0135] Each of the first tape 101b and the second tape 102b is, for example, a protective tape similar to the first tape member 50 of the first embodiment described above. Each of the first tape 101c and the second tape 102c is, for example, a double-sided tape. When the first tape 101c is a double-sided tape, the first tape 101c further has a first adhesive layer 52d on a surface opposite to the surface on which the first adhesive layer 52c is laminated in the first base material 51c. When the second tape 102c is a double-sided tape, the second tape 102c further has a second adhesive layer 62d on a surface opposite to the surface on which the second adhesive layer 62c is laminated in the second base material 61c. The first tape 101c can have the first adhesive layer 52c attached to the first tape 101b, while the first adhesive layer 52d can be attached to the arrangement location of the flat portion 45. The second tape 102c can have the second adhesive layer 62c attached to the second tape 102b, while the second adhesive layer 62d can be attached to the arrangement location of the flat portion 45.

[0136] According to the seventh embodiment, in addition to the same advantageous effects as those of (1-1) to (1-5), (1-7), and (1-9) to (1-11) of the first embodiment and the second embodiment, the following advantageous effects are achieved.

[0137] (7-1) Each of the first tape member 50K and the second tape member 60K has a plurality of tapes 100 overlapping each other in the second direction Z. With this configuration, the thickness of each of the first tape member 50K and the second tape member 60K in the second direction Z can be adjusted by adjusting the number of tapes 100. Furthermore, each of the first tape member 50K and the second tape member 60K can be constructed from a plurality of types of tapes 100.

[0138] (7-2) Each of the first tape member 50K and the second tape member 60K includes a protective tape having a base material that is thicker than the base material of an electric wire tie tape used to tie electric wires, and an adhesive layer laminated on one side of the base material. Each of the first tape member 50K and the second tape member 60K includes a metal tape having a band-shaped metal base material. Each of the first tape member 50K and the second tape member 60K includes a double-sided tape having a band-shaped base material and adhesive layers laminated on both sides of the base material.

[0139] According to this configuration, when the first tape member 50K and the second tape member 60K each include a protective tape, the portion of the flat portion 45 that is covered with the protective tape can be protected from surrounding members by the protective tape.

[0140] When the first tape member 50K and the second tape member 60K each include a metal tape, in the portion of the flat portion 45 where the metal tape is attached, the metal tape can suppress radiation of electromagnetic noise from the electric wire 41 in the flat portion 45 to the outside. Furthermore, in the same portion, the metal tape can suppress intrusion of electromagnetic noise from the outside into the electric wire 41 in the flat portion 45. Furthermore, in the same portion, the metal tape can reflect radiant heat, so that a rise in temperature of the electric wire 41 in the flat portion 45 can be suppressed.

[0141] Furthermore, when the first tape member 50K and the second tape member 60K each include a double-sided tape, one of the two adhesive layers of the double-sided tape can be attached to the flat portion 45. Furthermore, by attaching the other adhesive layer to the routing location of the flat portion 45, the flat portion 45 can be easily fixed. In other words, there is no need to prepare a separate part for fixing the flat portion 45.

[0142] Eighth embodiment Hereinafter, an eighth embodiment of the wire harness will be described. In the eighth embodiment, the same components as or corresponding components to the above-described embodiments are denoted by the same reference numerals, and the description of the components will be omitted in part or in whole.

[0143] As shown in Fig. 16 and Fig. 17, the wire harness 30L of the eighth embodiment includes a wire bundle 40 having a flat portion 45, a first tape member 50L, and a second tape member 60L. Fig. 16 is a longitudinal sectional view showing a part of the wire harness 30L, and is a sectional view taken along line 16-16 in Fig. 17. Fig. 17 is a transverse sectional view showing a part of the wire harness 30L, and is a sectional view taken along line 17-17 in Fig. 16.

[0144] The first tape member 50L and the second tape member 60L are attached to each other from both sides in the thickness direction of the flat portion 45, sandwiching the flat portion 45. The electric wires 41 in the flat portion 45 are integrally held by the first tape member 50L and the second tape member 60L.

[0145] Each of the first tape member 50L and the second tape member 60L has, for example, a band shape extending overall along the extension direction X. At least one of the first tape member 50L and the second tape member 60L may have a plurality of tapes 100 of the same type superimposed on each other in the second direction Z. For example, each of the first tape member 50L and the second tape member 60L has a plurality of tapes 100 of the same type superimposed on each other in the second direction Z.

[0146] For example, the first tape member 50L has two first tapes 101a and 101b as the multiple tapes 100. For example, the first tape 101a is a metal tape similar to the seventh embodiment, and the first tape 101b is the same type of metal tape as the first tape 101a.

[0147] For example, the second tape member 60L has two second tapes 102a and 102b as the multiple tapes 100. The number of tapes 100 included in each of the first tape member 50L and the second tape member 60L is Two Not limited to, Three or more. The number of tapes 100 in the first tape member 50L and the number of tapes 100 in the second tape member 60L may be different. For example, the second tape 102a is a metal tape as in the seventh embodiment, and the second tape 102b is the same type of metal tape as the second tape 102a.

[0148] The first tapes 101a, 101b and the second tapes 102a, 102b are arranged on the flat portion 45 in the same manner as in the seventh embodiment. According to the eighth embodiment, in addition to the same advantageous effects as those of (1-1) to (1-5), (1-7), and (1-9) to (1-11) of the first embodiment and the second embodiment, the following advantageous effects are achieved.

[0149] (8-1) Each of the first tape member 50L and the second tape member 60L has a plurality of tapes 100 of the same type that are overlapped on one another in the second direction Z. With this configuration, the thickness of each of the first tape member 50L and the second tape member 60L in the second direction Z can be easily increased by overlapping a plurality of tapes 100 of the same type. Furthermore, the portion of the flat portion 45 that is covered by the portion where the plurality of tapes 100 of the same type are overlapped can be protected from surrounding members by the portion where the plurality of tapes 100 of the same type are overlapped. Furthermore, multiple tapes 100 can be prepared more easily than when multiple types of tapes 100 are overlapped.

[0150] (8-2) Each of the first tape member 50L and the second tape member 60L includes a metal tape having a band-shaped metal base material. According to this configuration, when each of the first tape member 50L and the second tape member 60L includes a metal tape, in the portion of the flat portion 45 where the metal tape is attached, the metal tape can suppress radiation of electromagnetic noise from the electric wire 41 in the flat portion 45 to the outside. Furthermore, in this portion, the metal tape can suppress intrusion of electromagnetic noise from the outside into the electric wire 41 in the flat portion 45. Furthermore, in this portion, the metal tape can reflect radiant heat, so that a rise in temperature of the electric wire 41 in the flat portion 45 can be suppressed.

[0151] <Ninth embodiment> Hereinafter, a ninth embodiment of the wire harness will be described. In the ninth embodiment, the same components as or corresponding components to the above-described embodiments are denoted by the same reference numerals, and the description of the components will be omitted in part or in whole.

[0152] 18 and 19, a wire harness 30M of the ninth embodiment includes a wire bundle 40 having a flat portion 45, the first tape member 50 of the second embodiment, and a second tape member 60M. Note that FIG. 19 is a cross-sectional view taken along line 19-19 in FIG. 18.

[0153] Each of the first tape member 50 and the second tape member 60M has at least one tape 100. For example, each of the first tape member 50 and the second tape member 60M has one tape 100.

[0154] The tape 100 constituting the first tape member 50 has a first width W11. The first width W11 is the length of the tape 100 in the first direction Y. The second tape member 60M is a protective tape similar to the second tape member 60 of the second embodiment. That is, the tape 100 constituting the second tape member 60M is a protective tape. The tape 100 constituting the second tape member 60M has a second width W21 that is wider than the first width W11. The second width W21 is the length of the tape 100 in the first direction Y.

[0155] The tape 100 having the first width W11, i.e., the first tape member 50, and the tape 100 having the second width W21, i.e., the second tape member 60M, are overlapped on the flat portion 45 from both sides in the second direction Z. The tape 100 having the second width W21 is wider in the first direction Y than the tape 100 having the first width W11. Therefore, the tape 100 having the second width W21 has an attachment portion 110 that does not overlap the tape 100 having the first width W11 in the second direction Z in at least one end region of both end regions in the first direction Y. For example, the tape 100 having the second width W21 has an attachment portion 110 in each of both end regions in the first direction Y. The attachment portion 110 does not cover the second adhesive layer 62 by the tape 100 having the first width W11. Therefore, the attachment portion 110 can be attached to the arrangement location of the flat portion 45.

[0156] In addition, during transportation of the wire harness 30M, etc., until the flat portion 45 is arranged at the wiring location, the release paper 111 may be attached to the second adhesive layer 62 of the attachment portion 110. In FIG. 19, the release paper 111 is illustrated by a two-dot chain line. When the release paper 111 is not attached to the second adhesive layer 62 of the attachment portion 110, the tape 100 having the second width W21 may be folded so that the attachment portion 110 overlaps the end region in the first direction Y of the tape 100 having the first width W11. In this case, the second adhesive layer 62 of the attachment portion 110 is attached to the surface of the first base material 51 opposite to the surface on which the first adhesive layer 52 is laminated. Then, when the flat portion 45 is arranged at the wiring location, the attachment portion 110 is peeled off from the tape 100 having the first width W11 and then attached to the wiring location.

[0157] According to the ninth embodiment, in addition to the same advantageous effects as those of the first and second embodiments, the following advantageous effects are achieved. (9-1) Each of the first tape member 50 and the second tape member 60M has at least one tape 100. The first tape member 50 has a tape 100 having a first width W11. The second tape member 60M has a tape 100 having a second width W21 that is wider than the first width W11. The tape 100 having the first width W11 and the tape 100 having the second width W21 are overlapped on the flat portion 45 from both sides in the second direction Z.

[0158] According to this configuration, the tape 100 having the second width W21 protrudes in the width direction of the flat portion 45 more than the tape 100 having the first width W11. Therefore, the flat portion 45 can be easily fixed by attaching the portion of the tape 100 having the second width W21 that protrudes in the width direction of the flat portion 45 more than the tape 100 having the first width W11 to the location where the flat portion 45 is routed. In other words, it is not necessary to prepare a separate part for fixing the flat portion 45.

[0159] Tenth embodiment Hereinafter, a tenth embodiment of the wire harness will be described. In the tenth embodiment, the same components as or corresponding components to the above-described embodiments are denoted by the same reference numerals, and the description of the components will be omitted in part or in whole.

[0160] 20 and 21, a wire harness 30N according to the tenth embodiment includes a wire bundle 40 having a flat portion 45, a first tape member 50N, and a second tape member 60N. Note that FIG. 21 is a cross-sectional view taken along line 21-21 in FIG.

[0161] The first tape member 50N and the second tape member 60N are attached to each other from both sides in the thickness direction of the flat portion 45, sandwiching the flat portion 45. The electric wires 41 in the flat portion 45 are integrally held by the first tape member 50N and the second tape member 60N.

[0162] The first tape member 50N has, for example, a band shape extending overall along the extension direction X. The first tape member 50N has a plurality of tapes 100. For example, the first tape member 50N has three first tapes 101a, 101b, and 101c as the plurality of tapes 100. Note that the number of tapes 100 included in the first tape member 50N is not limited to three, and may be two or four or more.

[0163] The first tape 101a is directly attached to the flat portion 45. The first tape 101b is directly overlapped on the first tape 101a in the second direction Z. The first tape 101c is directly overlapped on the first tape 101b in the second direction Z. The first tapes 101a, 101b, and 101c are overlapped such that, for example, their respective centers in the extension direction X overlap each other in the second direction Z.

[0164] The first tapes 101a, 101b, and 101c may have the same width in the first direction Y. The first tapes 101a, 101b, and 101c may have different lengths in the extending direction X. For example, the first tape member 50N has a first tape 101b having a length L1b and a first tape 101a having a length L1a longer than the length L1b. In this case, the length L1b corresponds to the "first length" and the length L1a corresponds to the "second length". For example, the first tape member 50N has a first tape 101c having a length L1c and a first tape 101b having a length L1b longer than the length L1c. In this case, the length L1c corresponds to the "first length" and the length L1b corresponds to the "second length". Also, for example, the first tape member 50N has a first tape 101c having a length L1c and a first tape 101a having a length L1a longer than length L1c. In this case, length L1c corresponds to the "first length" and length L1a corresponds to the "second length."

[0165] The second tape member 60N has, for example, a band shape extending along the extension direction X as a whole. The second tape member 60N has a plurality of tapes 100. For example, the second tape member 60N has three second tapes 102a, 102b, and 102c as the plurality of tapes 100. Note that the number of tapes 100 in the second tape member 60N is not limited to three, and may be two or four or more. Furthermore, the number of tapes 100 in the second tape member 60N may be different from the number of tapes 100 in the first tape member 50N.

[0166] The second tape 102a is attached directly to the flat portion 45 at a position where the flat portion 45 is sandwiched between the second tape 102a and the first tape 101a. The position of the second tape 102a in the extension direction X is, for example, the same position as the position of the first tape 101a in the extension direction X. The second tape 102b is directly overlapped on the second tape 102a in the second direction Z. The second tape 102c is directly overlapped on the second tape 102b in the second direction Z. The second tapes 102a, 102b, and 102c are overlapped such that, for example, the centers of the second tapes 102a, 102b, and 102c in the extension direction X overlap each other in the second direction Z.

[0167] The second tapes 102a, 102b, and 102c may have the same width in the first direction Y. The second tapes 102a, 102b, and 102c may have different lengths in the extending direction X. For example, the length L2a of the second tape 102a in the extending direction X is equal to the length L1a of the first tape 101a in the extending direction X. For example, the length L2b of the second tape 102b in the extending direction X is equal to the length L1b of the first tape 101b in the extending direction X. For example, the length L2c of the second tape 102c in the extending direction X is equal to the length L1c of the first tape 101c in the extending direction X. Therefore, for example, the length L2b is shorter than the length L2a. For example, the length L2c is shorter than the length L2b. The lengths L1a and L2a may be different from each other. Similarly, the lengths L1b and L2b, and the lengths L1c and L2c may be different from each other.

[0168] First tape 101a and second tape 102a, first tape 101b and Second Tape 102b For example, the first tape 101c and the second tape 102c are located at the same position in the extending direction X. Second Tape 102b For example, the first tape 101c and the second tape 102c are paired with each other.

[0169] Each of the first tape 101a and the second tape 102a is, for example, a metal tape similar to the seventh embodiment. Each of the first tape 101b and the second tape 102b is, for example, a protective tape similar to the seventh embodiment. Each of the first tape 101c and the second tape 102c is, for example, a double-sided tape similar to the seventh embodiment.

[0170] The flat portion 45 is fixed to the routing location by, for example, attaching at least one of the first adhesive layer 52d of the first tape 101c and the second adhesive layer 62d of the second tape 102c to the routing location of the flat portion 45.

[0171] According to the tenth embodiment, in addition to the same advantageous effects as those of (1-1) to (1-5), (1-7), and (1-9) to (1-11) of the first embodiment, the second embodiment, and the seventh embodiment, the following advantageous effects are achieved.

[0172] (10-1) The first tape member 50N has a first tape 101c, and first tapes 101a and 101b that are longer than the first tape 101c in the extending direction X. The first tape 101a is longer than the first tape 101b in the extending direction X. In addition, the second tape member 60N has a second tape 102c, and second tapes 102a and 102b that are longer than the second tape 102c in the extending direction X. The second tape 102a is longer than the second tape 102b in the extending direction X.

[0173] According to this configuration, in the first tape member 50N, the portion where the first tapes 101b and 101c are overlapped with the first tape 101a is thicker in the second direction Z than the portion where the first tapes 101b and 101c are not overlapped. In the first tape member 50N, the portion where the first tape 101a, the first tape 101b, and the first tape 101c overlap in the second direction Z is the thickest in the second direction Z. Therefore, by arranging a portion where the first tape 101a and at least one of the first tapes 101b and 101c overlap each other in a portion of the first tape member 50N where it is desired to increase the thickness in the second direction Z, it is possible to easily increase the thickness partially. For example, by arranging a portion where the first tapes 101a, 101b, and 101c overlap each other in a portion where it is desired to increase the protection of the flat portion 45, it is possible to easily increase the protection of the portion from the surrounding members. The first tape member 50N can also partially have the functions of the first tapes 101b, 101c in the extending direction X. Furthermore, the first tape member 50N can entirely have the functions of the first tape 101a in the extending direction X. The second tape member 60N also has the same effects.

[0174] <Eleventh embodiment> Hereinafter, an eleventh embodiment of the wire harness will be described. In the eleventh embodiment, the same components as or corresponding components to those of the above-described embodiments are denoted by the same reference numerals, and the description of the components will be omitted in part or in whole.

[0175] As shown in Fig. 22, Fig. 23, and Fig. 24, the wire harness 30P of the eleventh embodiment includes a wire bundle 40 having a flat portion 45, a first tape member 50P, and a second tape member 60P. Fig. 23 is a cross-sectional view taken along line 23-23 in Fig. 22. Fig. 24 is a cross-sectional view taken along line 24-24 in Fig. 23.

[0176] The first tape member 50P and the second tape member 60P are attached to each other from both sides in the thickness direction of the flat portion 45, sandwiching the flat portion 45. The electric wires 41 in the flat portion 45 are integrally held by the first tape member 50P and the second tape member 60P.

[0177] The first tape member 50P has, for example, a band shape extending overall along the extension direction X. The first tape member 50P has a plurality of tapes 100. For example, the first tape member 50P has four first tapes 101e, 101a, 101b, and 101c as the plurality of tapes 100. Note that the number of tapes 100 included in the first tape member 50P is not limited to four, and may be two, three, five or more.

[0178] The second tape member 60P has, for example, a band shape extending overall along the extension direction X. The second tape member 60P has a plurality of tapes 100. For example, the second tape member 60P has four second tapes 102e, 102a, 102b, and 102c as the plurality of tapes 100. Note that the number of tapes 100 in the second tape member 60P is not limited to four, and may be the same as the number of tapes 100 in the first tape member 50P.

[0179] Each of the multiple first tapes 101e, 101a, 101b, and 101c included in the first tape member 50P is paired with a multiple second tapes 102e, 102a, 102b, and 102c included in the second tape member 60P. That is, the first tape 101e and the second tape 102e, the first tape 101a and the second tape 102a, and the first tape 101b and Second Tape 102b The first tape 101c and the second tape 102c are each paired with each other. In this manner, the first tape member 50P and the second tape member 60P each have, for example, four pairs of tapes 100.

[0180] The pair of tapes 100 have the same length in the extension direction X. Furthermore, the length in the extension direction X is set individually for each pair of tapes 100. For example, the pair of first tape 101e and second tape 102e have the same length in the extension direction X. Furthermore, for example, each of the first tapes 101a, 101b, and 101c has a shorter length in the extension direction X than the first tape 101e.

[0181] The pair of first tape 101e and second tape 102e are overlapped with each other from both sides in the second direction Z, with the flat portion 45 between them, and are positioned equal to each other in the extending direction X. The pair of first tape 101a and second tape 102a are overlapped with each other from both sides in the second direction Z, with the flat portion 45 between them, and are positioned equal to each other in the extending direction X. The pair of first tape 101b and second tape 102b are overlapped with each other from both sides in the second direction Z, with the flat portion 45 between them, and are positioned equal to each other in the extending direction X. The pair of first tape 101c and second tape 102c are overlapped with each other from both sides in the second direction Z, with the flat portion 45 between them, and are positioned equal to each other in the extending direction X.

[0182] At least a portion of each of the multiple tapes 100 included in the first tape member 50P overlaps at least one of the multiple tapes 100 included in the first tape member 50P in the second direction Z. For example, the first tape 101e is directly attached to the flat portion 45. The first tape 101a is directly overlapped with the first tape 101e in the second direction Z. For example, the first tape 101a overlaps with the first tape 101e over the entirety in the extending direction X. For example, one end of the first tape 101b is directly overlapped with the first tape 101a, and the other end is directly overlapped with the first tape 101e. Then, the first tape 101b overlaps with the first tape 101e over the entirety in the extending direction X in the second direction Z, and a portion of the range in the extending direction X overlaps with the first tape 101a in the second direction Z. The first tape 101c is disposed, for example, at a position shifted in the extension direction X with respect to the first tape 101a and the first tape 101b. That is, the first tape 101c may be overlapped on the first tape 101e in the second direction Z at a position where it does not overlap either of the first tapes 101a and 101b in the second direction Z. And, the first tape 101c is, for example, directly overlapped on the first tape 101e in the second direction Z over the entirety in the extension direction X.

[0183] At least a portion of each of the multiple tapes 100 included in the second tape member 60P overlaps in the second direction Z with at least one of the multiple tapes 100 included in the second tape member 60P. In particular, the second tape 102e is attached directly to the flat portion 45 on the opposite side of the flat portion 45 to the first tape 101e, similar to the paired first tape 101e. The second tape 102a is overlaid on the flat portion 45 on the opposite side of the first tape member 50P, similar to the paired first tape 101a. The second tape 102b is overlaid on the flat portion 45 on the opposite side of the first tape member 50P, similar to the paired first tape 101b. The second tape 102c is overlaid on the flat portion 45 on the opposite side of the first tape member 50P, similar to the paired first tape 101b. 1st Tape 101c Similarly, it is overlapped on the flat portion 45.

[0184] The first tape 101e has, for example, a strip-shaped first base material 51e and a first adhesive layer 52e laminated on one side of the first base material 51e. The second tape 102e has, for example, a strip-shaped second base material 61e and a second adhesive layer 62e laminated on one side of the second base material 61e. Each of the first tape 101e and the second tape 102e is, for example, an electric wire bundling tape that is generally used to bundle electric wires. The electric wire bundling tape is, for example, a polyvinyl chloride (PVC) tape.

[0185] Each of the first tape 101a and the second tape 102a is, for example, a metal tape similar to the seventh embodiment. Each of the first tape 101b and the second tape 102b is, for example, a protective tape similar to the seventh embodiment. Each of the first tape 101c and the second tape 102c is, for example, a double-sided tape similar to the seventh embodiment.

[0186] At least one pair of tapes 100 among the multiple pairs of tapes 100 have different widths. The width is the length of the tape 100 in the first direction Y. For example, among four pairs of tapes 100, the first tape 101a and the second tape 102a that form a pair have different widths. For example, the first tape 101a is wider than the second tape 102a. More specifically, the second tape 102a has a first width W12. The first tape 101a has a second width W22 that is wider than the first width W12. The first tape 101a has an attachment portion 110 that does not overlap the second tape 102a in the second direction Z in at least one end region of both end regions in the first direction Y. For example, the first tape 101a has an attachment portion 110 in each of both end regions in the first direction Y.

[0187] A part of the flat portion 45 is fixed to the routing location by, for example, attaching at least one of the first adhesive layer 52d of the first tape 101c and the second adhesive layer 62d of the second tape 102c to the routing location of the flat portion 45. A part of the flat portion 45 is fixed to the routing location by attaching the attachment portion 110 to the routing location of the flat portion 45. Note that, until the flat portion 45 is arranged at the routing location, the first adhesive layer 52a of the attachment portion 110 may be prevented from sticking to other surrounding members, as in the above ninth embodiment.

[0188] According to the eleventh embodiment, in addition to the same advantageous effects as those of (1-1) to (1-5), (1-7), and (1-9) to (1-11) of the first embodiment, the second embodiment, the seventh embodiment, the ninth embodiment, and the tenth embodiment, the following advantageous effects are achieved.

[0189] (11-1) Each of the first tape member 50P and the second tape member 60P includes an electric wire tie tape used for bundling electric wires, the electric wire tie tape having a band-shaped base material and an adhesive layer laminated on one side of the base material. According to this configuration, since the electric wire tie tape is easy to obtain, if each of the first tape member 50P and the second tape member 60P includes the electric wire tie tape, it becomes easy to prepare each of the first tape member 50P and the second tape member 60P.

[0190] (11-2) The first tape 101e and the second tape 102e are electric wire binding tapes. The electric wire binding tapes are polyvinyl chloride tapes. With this configuration, the electric wire binding tapes used as the material for each of the first tape member 50P and the second tape member 60P can be more easily obtained.

[0191] (11-3) Each of the multiple tapes 100 included in the first tape member 50P is paired with the multiple tapes 100 included in the second tape member 60P. The pair of tapes 100 are overlapped with each other from both sides in the second direction Z, sandwiching the flat portion 45 therebetween, and are positioned at the same position in the extending direction X. A pair of tapes 100 among the multiple pairs of tapes 100, i.e., the pair of first tape 101a and second tape 102a, have different widths. At least a portion of each of the multiple tapes 100 included in the first tape member 50P overlaps in the second direction Z with at least one tape 100 among the multiple tapes 100 included in the first tape member 50P. At least a portion of each of the multiple tapes 100 included in the second tape member 60P overlaps in the second direction Z with at least one tape 100 among the multiple tapes 100 included in the second tape member 60P.

[0192] According to this configuration, when a pair of tapes 100 having different widths are overlapped with each other, the wider tape 100 protrudes in the width direction of the flat portion 45 more than the narrower tape 100. That is, when the pair of first tape 101a and second tape 102a are overlapped with each other, the first tape 101a protrudes in the first direction Y more than the second tape 102a. Therefore, the flat portion 45 can be easily fixed by attaching the portion of the wider first tape 101a that protrudes in the first direction Y more than the narrower second tape 102a to the arrangement location of the flat portion 45. That is, it is not necessary to prepare a separate part for fixing the flat portion 45.

[0193] Furthermore, in each of the first tape member 50P and the second tape member 60P, each of the multiple tapes 100 may be arranged so as to overlap another tape 100 in the second direction Z. Therefore, each of the multiple tapes 100 can be easily arranged at a desired position in the extension direction X according to the function of each of the multiple tapes 100. Furthermore, by arranging the overlapping portion of the multiple tapes 100 so as to overlap a portion of the flat portion 45 where protection should be strengthened, protection of that portion from surrounding members can be strengthened.

[0194] <Example of change> The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other to the extent that no technical contradiction occurs.

[0195] 25 shows a wire harness 30F having a single-layer bent portion 49 instead of the overlapped bent portion 48 of the wire harness 30E of the sixth embodiment. More specifically, the electric wire bundle 40E has a single-layer bent portion 49 in which the electric wires 41 are bent while being arranged flat at a position shifted from the flat portion 45E in the extending direction X. The single-layer bent portion 49 has a similar configuration to the flat bent portion 47 of the fifth embodiment. That is, the electric wires 41 in the single-layer bent portion 49 are arranged in a row along a direction perpendicular to the thickness direction of the single-layer bent portion 49 when viewed from the thickness direction of the single-layer bent portion 49, and are bent while maintaining the row arrangement.

[0196] The wire harness 30F includes a third tape member 91 and a fourth tape member 92 that are bonded together while sandwiching the single-layer bent portion 49 from both sides in the thickness direction of the single-layer bent portion 49. The third tape member 91 and the fourth tape member 92 maintain the arrangement and bent shape of the multiple electric wires 41 in the single-layer bent portion 49. The third tape member 91 and the fourth tape member 92 have the same configuration as the first tape member 50 and the second tape member 60.

[0197] In this way, the single-layer bent portion 49, where the multiple electric wires 41 are bent at a position away from the flat portion 45E in the electric wire bundle 40E, can also be easily maintained in a flat state by the third tape member 91 and the fourth tape member 92. In addition, the single-layer bent portion 49 can be easily maintained in a bent state by the third tape member 91 and the fourth tape member 92. Therefore, the wire harness 30F can be easily arranged in a narrow space with the electric wire bundle 40E in a bent state.

[0198] As shown in Figs. 26 and 27, in the first embodiment, the flat portion 45 may be maintained in a curved shape by the first tape member 50 and the second tape member 60 when viewed in the width direction of the flat portion 45. Fig. 27 is a cross-sectional view taken along line 27-27 in Fig. 26. For example, the first tape member 50 and the second tape member 60 maintain the flat portion 45 in a curved shape by the adhesive forces of the first adhesive layer 52 and the second adhesive layer 62, and the first base material 51 and the second base material 61. In this way, the flat portion 45 can be easily arranged when the location where the flat portion 45 is to be routed is curved. The second to eleventh embodiments may also be modified in a similar manner.

[0199] In the tenth embodiment, each of the first tapes 101b, 101c may be disposed such that the center thereof in the extending direction X is shifted in the extending direction X with respect to the center of the first tape 101a in the extending direction X. The second tapes 102b, 102c may be similarly modified.

[0200] In the above 9th embodiment, the tape 100 having the second width W21 may be overlapped with the tape 100 having the first width W11 so as to have the adhesive portion 110 only in one of the end regions in the first direction Y. The same may be done in the above 11th embodiment.

[0201] In the seventh embodiment, the positions of the first tapes 101a, 101b, and 101c in the extension direction X do not have to be the same as each other. However, at least a portion of each of the first tapes 101a, 101b, and 101c overlaps with the other first tapes in the second direction Z. The same may be true for the second tapes 102a, 102b, and 102c.

[0202] In the seventh embodiment, the widths of the first tapes 101a, 101b, and 101c in the first direction Y may be different from one another. For example, the first tape 101b and the first tape 101c may have the same width in the first direction Y, and the first tape 101a may be wider in the first direction Y than the first tapes 101b and 101c. The first tapes 101a, 101b, and 101c may have different widths. The second tapes 102a, 102b, and 102c may also be modified in a similar manner. The eighth and tenth embodiments may also be modified in a similar manner.

[0203] In the first embodiment described above, the first tape member 50 and the second tape member 60 may be different types. In this way, the first tape member 50 and the second tape member 60 can be selected depending on the environment of the location where the flat portion 45 is routed. The same change may be made in the second to sixth embodiments described above.

[0204] In the seventh embodiment described above, at least one of the first tape member 50K and the second tape member 60K may include at least one of a wire binding tape, a protective tape, a sound-absorbing tape, a heat-resistant tape, a metal tape, a double-sided tape, a hook-and-loop fastener, and a magnetic tape.

[0205] The electric wire bundling tape is a tape that has a band-shaped substrate and an adhesive layer laminated on one side of the substrate and is generally used for bundling electric wires. Since the electric wire bundling tape is easy to obtain, if at least one of the first tape member 50K and the second tape member 60K contains the electric wire bundling tape, it becomes easy to prepare at least one of the first tape member 50K and the second tape member 60K.

[0206] The sound deadening tape is a tape having a strip-shaped porous base material. For example, when the first tape 101c is a sound deadening tape, the first base material 51c is, for example, any one of a strip-shaped sponge, a strip-shaped nonwoven fabric, a strip-shaped woven fabric, etc. When at least one of the first tape member 50K and the second tape member 60K includes a sound deadening tape, it is possible to suppress the generation of abnormal noise when the portion of the flat portion 45 to which the sound deadening tape is attached collides with or rubs against a surrounding member.

[0207] The heat-resistant tape is a tape that has better heat resistance than electric wire binding tapes that are generally used to bind electric wires. An example of the heat-resistant tape is a polyethylene terephthalate (PET) tape. When at least one of the first tape member 50K and the second tape member 60K contains a heat-resistant tape, the heat resistance of the flat portion 45 can be improved. Therefore, the flat portion 45 can be arranged in a place where the temperature becomes high within the heat resistance temperature range of the heat-resistant tape.

[0208] A strip-shaped hook-and-loop fastener can be used as the hook-and-loop fastener. For example, when the first tape 101c is a hook-and-loop fastener, the first base material 51c has a hook structure portion (not shown) raised into a hook shape on the surface of the first base material 51c opposite to the first adhesive layer 52c. The first base material 51c may have a loop structure portion (not shown) raised into a loop shape instead of the hook structure portion on the surface of the first base material 51c opposite to the first adhesive layer 52c. The first base material 51c may have both a hook structure portion and a loop structure portion on the surface of the first base material 51c opposite to the first adhesive layer 52c. The first base material 51c is arranged such that the surface having the first adhesive layer 52c faces the flat portion 45, and the surface of the first base material 51c opposite to the first adhesive layer 52c faces the outer periphery of the flat portion 45. When at least one of the first tape member 50K and the second tape member 60K includes a hook-and-loop fastener, if the location where the flat portion 45 is to be routed has a surface to which a hook-and-loop fastener can be attached, the flat portion 45 can be easily fixed using the hook-and-loop fastener.

[0209] A magnetic tape is a tape having a substrate that is a strip-shaped magnet. For example, when the first tape 101c is a magnetic tape, the first substrate 51c is a strip-shaped magnet. When at least one of the first tape member 50K and the second tape member 60K includes a magnetic tape, if the location where the flat portion 45 is routed has a portion made of a material that is attracted to a magnet, the magnetic tape can be used to easily fix the flat portion 45 by magnetic force.

[0210] The first to sixth embodiments and the eighth to eleventh embodiments may also be modified in a similar manner. In the first embodiment, in the first tape member 50 and the second tape member 60 that are bonded to each other, either the first adhesive layer 52 or the second adhesive layer 62 may be omitted. For example, when the first tape member 50 has the first adhesive layer 52, the second tape member 60 does not need to have the second adhesive layer 62. The second to sixth embodiments and the ninth embodiment may be modified in a similar manner. In the seventh embodiment, the eighth embodiment, and the tenth embodiment, the first tape 101a and the second tape 102a may be modified in a similar manner. In the eleventh embodiment, the first tape 101e and the second tape 102e may be modified in a similar manner.

[0211] The number of electric wires 41 in each of the electric wire bundles 40, 40C, 40E is not limited to that in the above-described embodiment, but may be two or more. In the first embodiment, the configuration of the flat portion 45 in which the electric wire bundle 40 and the electric wires 41 are arranged flat is not limited to the configuration in the above embodiment. The same applies to the above second to eleventh embodiments.

[0212] For example, instead of the electric wire bundle 40 of the first embodiment, an electric wire bundle 40G shown in FIG. 28 may be provided in the wire harness 30. The electric wire bundle 40G has two types of electric wires 41a and 41b having different diameters. The electric wire bundle 40G has, for example, three electric wires 41a and four electric wires 41b having a diameter smaller than that of the electric wires 41a.
