[0010] [Description of Embodiments of the Invention] First, embodiments of the present invention will be described by way of examples. [1] The wiring harness of the present invention comprises: a cylindrical member; an electric wire member passing through the cylindrical member; a sheet material having self-welding properties and wound around the outer periphery of the electric wire member; a first belt member wound around the outer periphery of the sheet material; and a second belt member wound around the outer periphery of a first end portion in the axial direction of the cylindrical member and the outer periphery of a portion of the first belt member arranged outside the cylindrical member, wherein the electric wire member has a plurality of electric wires, and the sheet material is formed in a manner to fill gaps between the plurality of electric wires.

[0011] According to this structure, the gaps between the plurality of wires are buried by a sheet material having self-welding properties. Thus, it is possible to suppress liquids such as water from penetrating into the interior of the cylindrical member through the gaps between the plurality of wires. In addition, the second belt member is wound around the outer periphery of the first end of the cylindrical member and the outer periphery of the first belt member of the portion arranged outside the cylindrical member. By using the second belt member, the gap between the inner peripheral surface of the cylindrical member and the outer peripheral surface of the first belt member can be blocked. Therefore, it is possible to suppress liquid from penetrating into the interior of the cylindrical member through the gap between the inner peripheral surface of the cylindrical member and the outer peripheral surface of the first belt member. Furthermore, the sheet material that functions as a waterproof member is a structure that is wound around the outer periphery of the wire member, and the second belt member that functions as a waterproof member is a structure that is wound around the outer periphery of the cylindrical member and the outer periphery of the first belt member. Therefore, compared with the previous structure in which a wire sheath is provided on the outer side of the outer member, it is possible to suppress the overall size of the wire harness. Therefore, it has waterproof performance and can appropriately suppress the size of the wire harness. In addition, the "cylindrical" in this specification includes not only a cylindrical shape with a peripheral wall continuously formed throughout the entire circumference, but also a shape formed by combining multiple parts to form a cylindrical shape. The "cylindrical" in this specification includes a cylindrical shape with a circular outer edge shape, a cylindrical shape with a flat outer edge shape, and a cylindrical shape with a polygonal outer edge shape, and refers to a cylindrical shape with an outer edge shape consisting of any closed shape connected by straight lines or curves.

[0012] [2] In the above [1], preferably, the second tape member is wound around the outer circumference of the electric wire member at a portion exposed from the cylindrical member and the first tape member. According to this structure, the second belt member is wound around the outer periphery of the first end of the cylindrical member, the outer periphery of the first belt member exposed from the cylindrical member, and the outer periphery of the wire member exposed from the cylindrical member and the first belt member. As a result, the entire outer periphery of the first belt member exposed from the cylindrical member is covered by the second belt member, and a labyrinth structure is formed between the first belt member and the second belt member. Therefore, the waterproofness of the second belt member can be improved.

[0013] [3] In the above [1] or [2], it is preferred that there is also a third belt member, which is wound around the outer periphery of the portion of the tubular member exposed from the second belt member, the outer periphery of the second belt member, and the outer periphery of the portion of the wire member exposed from the second belt member.

[0014] According to this structure, the third belt member is wound around the outer periphery of the cylindrical member exposed from one end of the second belt member to the outer periphery of the electric wire member exposed from the other end of the second belt member. As a result, the entire outer periphery of the second belt member is covered by the third belt member, and a labyrinth structure is formed between the second belt member and the third belt member. Therefore, the second belt member and the third belt member can appropriately suppress the liquid from penetrating into the interior of the cylindrical member through the gap between the inner peripheral surface of the cylindrical member and the outer peripheral surface of the first belt member.

[0015] [4] The wiring harness of the present invention comprises: a cylindrical member; an electric wire member passing through the cylindrical member; a sheet material having self-welding properties and wound around the outer periphery of the electric wire member; a first belt member wound around the outer periphery of the sheet material; a cylindrical retaining body engaged with the inner side of the first end portion of the cylindrical member in the axial direction and surrounding the outer periphery of the first belt member; and a second belt member wound around the outer periphery of the first end portion of the cylindrical member, the outer periphery of the retaining body at a portion arranged outside the cylindrical member, and the outer periphery of the first belt member at a portion exposed from the retaining body or the outer periphery of the electric wire member at a portion exposed from the retaining body, the electric wire member having a plurality of electric wires, the sheet material being formed in a manner to fill gaps between the plurality of electric wires, and the friction coefficient of the outer peripheral surface of the retaining body being lower than the friction coefficient of the outer peripheral surface of the first belt member.

[0016] According to this structure, the same effect as the above-mentioned [1] can be achieved. Furthermore, the friction coefficient of the outer peripheral surface of the retaining body surrounding the outer periphery of the first belt member is lower than the friction coefficient of the outer peripheral surface of the first belt member. As a result, when the retaining body is inserted into the interior of the tubular member, the retaining body can slide easily relative to the inner peripheral surface of the tubular member. Therefore, the operability when the retaining body is inserted into the interior of the tubular member can be improved.

[0017] [5] In the above [4], preferably, the retaining body is arranged in a manner covering the entire outer circumference of the first belt member, and the second belt member is wrapped around the outer circumference of the first end of the tubular member, the outer circumference of the portion of the retaining body arranged outside the tubular member, and the outer circumference of the portion of the wire member exposed from the retaining body.

[0018] According to this structure, the entire first band member is housed inside the retaining body. In addition, the second band member is wound around the outer periphery of the first end of the cylindrical member, the outer periphery of the retaining body disposed outside the cylindrical member, and the outer periphery of the wire member exposed from the retaining body. The second band member can block the gap between the inner peripheral surface of the cylindrical member and the outer peripheral surface of the retaining body, and can block the gap between the inner peripheral surface of the retaining body and the outer peripheral surface of the wire member. Therefore, it is possible to prevent liquid from penetrating into the interior of the cylindrical member through the gap between the inner peripheral surface of the cylindrical member and the outer peripheral surface of the retaining body and the gap between the inner peripheral surface of the retaining body and the outer peripheral surface of the wire member.

[0019] [6] In the above [4] or [5], preferably, the retaining body has a first end portion on the retaining body side and a second end portion on the retaining body side in the axial direction of the retaining body, the first end portion on the retaining body side is arranged inside the cylindrical member, the second end portion on the retaining body side is arranged outside the cylindrical member, and the first end portion on the retaining body side is formed in a manner that becomes thinner as it moves from the second end portion on the retaining body side toward the opening end of the first end portion on the retaining body side.

[0020] According to this structure, the first end of the holder that is first inserted into the interior of the tubular member is formed into a shape that becomes increasingly thinner. Thus, it is easy to insert the holder into the interior of the tubular member. Therefore, the operability when inserting the holder into the interior of the tubular member can be improved.

[0021] [7] In the above [6], preferably, the second end portion on the holding body side has an engaging portion that engages with an end surface of the tubular member in the axial direction of the tubular member. According to this structure, an engaging portion that engages with the end face in the axial direction of the tubular member is provided at the second end portion of the retaining body. Therefore, when the retaining body is inserted into the interior of the tubular member, the retaining body can be easily positioned in the axial direction of the tubular member. Thus, the operability when the retaining body is inserted into the interior of the tubular member can be improved.

[0022] [8] In any one of the above [4] to [7], preferably, the retaining body has a first split body and a second split body, and the retaining body is formed into a cylindrical shape by combining the first split body and the second split body.

[0023] According to this structure, the retaining body is formed into a cylindrical shape in which the first band member is surrounded by the first split body and the second split body. Thus, although the retaining body is formed into a cylindrical shape, the retaining body can be installed on the wire member or the like after the retaining body is divided into the first split body and the second split body. That is, the retaining body can be installed on the wire member after the sheet material and the first band member are wound around the outer circumference of the wire member, for example, by dividing the retaining body into the first split body and the second split body. As a result, the assembly workability of the wire harness can be improved.

[0024] [9] In any one of [1] to [8] above, preferably, the first belt member is wound around the outer periphery of the wire member exposed from one end of the sheet in the longitudinal direction to the outer periphery of the wire member exposed from the other end of the sheet in the longitudinal direction.

[0025] According to this configuration, the first tape member is wound around the entire periphery of the sheet material, and the sheet material can be appropriately protected by the first tape member.

[10] In any one of the above [1] to [9], preferably, the plurality of electric wires include a plurality of first electric wires and a second electric wire different from the first electric wires, the electric wire component includes a tubular braided component surrounding the outer periphery of the plurality of first electric wires, the sheet is formed by integrating a first sheet, a second sheet and a third sheet, the first sheet fills the gaps between the plurality of first electric wires on the inner side of the braided component and fills the gaps between the braided component and the first electric wires, the second sheet covers the outer periphery of the braided component, and the third sheet fills the gaps between the second electric wires and the second sheet.

[0026] According to this structure, the first sheet is used to fill the gaps between the plurality of first electric wires and the gaps between the braided member and the first electric wire. In addition, the second sheet is used to cover the outer periphery of the braided member. Furthermore, the third sheet is used to fill the gaps between the second electric wire and the second sheet. In addition, the first sheet, the second sheet, and the third sheet are integrated. By using these first sheet, second sheet, and third sheet, it is possible to prevent liquid from penetrating into the interior of the cylindrical member through the gaps between the plurality of first electric wires, the gaps between the braided member and the first electric wire, and the gaps between the second electric wire and the second sheet.

[0027]

[11] In any one of [1] to

[10] above, preferably, the plurality of electric wires are arranged along a first direction, and the cross-sectional shape of the tubular member is formed into a flat shape that is longer in the first direction than in a second direction orthogonal to the first direction.

[0028] According to this structure, the cross-sectional shape of the cylindrical member is formed into a flat shape that is longer in the first direction in which the plurality of wires are arranged. Therefore, compared with a case in which the dimensions along the first direction and the dimensions along the second direction in the cross-sectional shape of the cylindrical member are equal to each other, the cylindrical member can be miniaturized in the second direction.

[0029] [Details of Embodiments of the Invention] The following is a reference to the attached Figure 1 A specific example of the wiring harness of the present invention is described. In each of the drawings, for the sake of convenience, a part of the structure is sometimes enlarged or simplified. In addition, the size ratios of each part are sometimes different in each drawing. In addition, in the cross-sectional view, in order to easily understand the cross-sectional structure of each component, the pear pattern is used instead of the section line of a part of the component. "Parallel", "orthogonal" or "vertical" in this specification not only includes the case of being strictly parallel, orthogonal or perpendicular, but also includes the case of being roughly parallel, orthogonal or perpendicular within the range of the effect of the present embodiment. In some of the drawings, the X-axis, Y-axis, and Z-axis that are orthogonal to each other are illustrated. In the following description, for convenience, the direction extending along the X-axis is referred to as the X-axis direction, the direction extending along the Y-axis is referred to as the Y-axis direction, and the direction extending along the Z-axis is referred to as the Z-axis direction. In addition, the present invention is not limited to these examples, but is shown by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0030] (First embodiment) Hereinafter, a first embodiment of the wire harness will be described. (Overall Structure of Wiring Harness 10) Figure 1 The wire harness 10 shown is mounted on a vehicle V such as a hybrid vehicle or an electric vehicle, for example. The wire harness 10 electrically connects two or more electrical devices M1, M2, M3, and M4. The wire harness 10 is formed in an elongated shape, for example, so as to extend in the front-rear direction of the vehicle V. The wire harness 10 is laid in the vehicle V, for example, so that the middle portion of the wire harness 10 in the longitudinal direction passes outside the vehicle, such as under the floor of the vehicle V.

[0031] The wire harness 10 includes a wire member 20 and a cylindrical member 50 through which the wire member 20 is inserted. The wire member 20 includes, for example, a first wire member 30 for electrically connecting the electric device M1 and the electric device M2 and a second wire member 40 for electrically connecting the electric device M3 and the electric device M4.

[0032] One end of the first wire component 30 in the length direction is electrically connected to the electrical device M1, and the other end of the first wire component 30 in the length direction is electrically connected to the electrical device M2. The electrical device M1 is, for example, an inverter disposed near the front of the vehicle V. The electrical device M2 is, for example, a high-voltage battery disposed behind the vehicle V relative to the electrical device M1. The electrical device M1 as an inverter is connected to an electric motor for driving wheels (not shown) that serves as a power source for the vehicle. The electrical device M1 as an inverter generates AC power from the DC power of the high-voltage battery and supplies the AC power to the electric motor. The electrical device M2 as a high-voltage battery is a battery that can supply a voltage of several hundred volts.

[0033] One end of the second wire component 40 in the length direction is electrically connected to the electrical device M3, and the other end of the second wire component 40 in the length direction is electrically connected to the electrical device M4. The electrical device M3 is, for example, an electrical connection box disposed near the front of the vehicle V. The electrical device M4 is, for example, a low-voltage battery disposed at the rear of the vehicle V relative to the electrical device M3. Examples of electrical connection boxes include relay boxes, fuse boxes, junction boxes, and the like. The electrical device M3 as an electrical connection box distributes the voltage supplied from the low-voltage battery to various devices mounted on the vehicle V. The electrical device M4 as a low-voltage battery is a battery that can supply a voltage lower than that of the high-voltage battery (for example, a voltage of 12 volts).

[0034] like Figure 2 and Figure 3 As shown in FIG. 1 , the first wire member 30 and the second wire member 40 are arranged side by side along the Y-axis direction inside the cylindrical member 50, for example. Figure 2 As shown, the first electric wire member 30 and the second electric wire member 40 are provided so as to extend in parallel with each other in the X-axis direction inside the cylindrical member 50, for example.

[0035] like Figure 2 As shown, the wire harness 10 includes a sheet 60 wound around the outer periphery of the electric wire member 20 and a first tape member 70 wound around the outer periphery of the sheet 60. The wire harness 10 includes a second tape member 80 wound around the outer periphery of the cylindrical member 50 and the outer periphery of the first tape member 70. The wire harness 10 includes, for example, a third tape member 90 wound around the outer periphery of the cylindrical member 50, the outer periphery of the second tape member 80, and the outer periphery of the electric wire member 20. The first tape member 70, the second tape member 80, and the third tape member 90 are, for example, a base material and an adhesive tape having an adhesive layer laminated on one side of the base material.

[0036] (Structure of the First Electric Wire Member 30) like Figure 2 and Figure 3As shown, the first wire member 30 has one or more wires 31. The first wire member 30 of this embodiment has two wires 31. The two wires 31 are arranged in parallel along the Y-axis direction. The first wire member 30 has a cylindrical braided member 35 that surrounds the outer periphery of the plurality of wires 31, for example.

[0037] Each electric wire 31 is a covered electric wire having a core wire 32 and an insulating coating 33, wherein the core wire 32 has conductivity and the insulating coating 33 covers the outer periphery of the core wire 32 and has insulation. Each electric wire 31 is, for example, a high-voltage electric wire that can cope with high voltage and large current. Each electric wire 31 can be, for example, an unshielded electric wire that does not have an electromagnetic shielding structure itself, or a shielded electric wire that has an electromagnetic shielding structure itself. Each electric wire 31 of the present embodiment is an unshielded electric wire.

[0038] As the core wire 32, for example, a stranded wire formed by twisting a plurality of metal wires, a single core wire composed of a single conductor, etc. can be used. As the single core wire, for example, a columnar conductor composed of a columnar metal rod with a solid structure inside, a cylindrical conductor with a hollow structure inside, etc. can be used. As the material of the core wire 32, for example, a metal material such as copper or aluminum can be used.

[0039] The insulating coating layer 33 covers, for example, the entire circumference of the outer peripheral surface of the core wire 32. The insulating coating layer 33 is made of, for example, a resin material having insulating properties. The cross-sectional shape of the wire 31 cut by a plane perpendicular to the length direction of each wire 31, that is, the cross-sectional shape of each wire 31 can be formed into any shape. The cross-sectional shape of each wire 31 can be formed into, for example, a circular, semicircular, polygonal, square, flat shape, etc. Figure 3 As shown, the cross-sectional shape of each wire 31 of the present embodiment is formed into a circle. In addition, in this specification, "flat shape" includes a rectangle, an oblong, an ellipse, etc. The "oblong" in this specification has a long side and a short side, except for a square. The "oblong" in this specification is a rounded rectangle composed of two parallel lines of approximately equal length and two semicircles. The "oblong" in this specification has a long side extending from the parallel lines and a short side extending in the direction in which the two parallel lines are arranged.

[0040] The braided member 35 is in the shape of an elongated tube as a whole. The braided member 35 is, for example, flexible. For example, a braided wire made of a plurality of metal wires or a braided wire made by combining metal wires and resin wires can be used as the braided member 35. The braided member 35 has a plurality of meshes 36. Although not shown in the figure, the two ends of the braided member 35 in the longitudinal direction are connected to each other, for example, at the electrical devices M1 and M2 (see Figure 1 ) etc. Such a braided member 35 functions as an electromagnetic shielding member.

[0041] The cross-sectional shape of the braided member 35 can be formed into any shape. For example, the cross-sectional shape of the braided member 35 is formed into a flat shape that is longer in the Y-axis direction than in the Z-axis direction. The cross-sectional shape of the braided member 35 of this embodiment is formed into an oblong shape with a long side extending in the Y-axis direction and a short side extending in the Z-axis direction. The inner peripheral surface of the braided member 35 may or may not be in direct contact with the outer peripheral surface of the wire 31.

[0042] (Structure of the Second Electric Wire Member 40) The second electric wire member 40 includes one or more electric wires 41. The second electric wire member 40 of the present embodiment includes one electric wire 41.

[0043] The electric wire 41 is a covered electric wire having a core wire 42 and an insulating coating 43, wherein the core wire 42 has conductivity and the insulating coating 43 surrounds the outer periphery of the core wire 42 and has insulation. The electric wire 41 is, for example, a low-voltage electric wire. The electric wire 41 can be, for example, either an unshielded electric wire or a shielded electric wire. The electric wire 41 of this embodiment is an unshielded electric wire.

[0044] For example, a stranded wire or a single-core wire can be used as the core wire 42. For example, a copper-based, aluminum-based, or other metal material can be used as the material of the core wire 42. The insulating coating layer 43 covers, for example, the entire circumference of the outer peripheral surface of the core wire 42. The insulating coating layer 43 is made of, for example, a resin material having insulating properties.

[0045] The cross-sectional shape of the electric wire 41 can be formed into any shape. The cross-sectional shape of the electric wire 41 of this embodiment is formed into a circular shape. The outer diameter of the electric wire 41 is larger than the outer diameter of each electric wire 31, for example.

[0046] The electric wire 41 and the plurality of electric wires 31 are arranged, for example, in the Y-axis direction. That is, the plurality of electric wires 31 and 41 included in the electric wire member 20 are arranged in a row in the Y-axis direction.

[0047] (Structure of the cylindrical member 50) The cylindrical member 50 is in the shape of an elongated cylinder as a whole. Figure 1 As shown, the cylindrical member 50, for example, partially accommodates the wire member 20. The cylindrical member 50, for example, accommodates the middle part of the length direction of the wire member 20 inside. The cylindrical member 50 protects the wire member 20 accommodated inside so that it is not affected by flying objects or water drops. As the cylindrical member 50, for example, a metal or resin tube, a resin protective member, a bellows composed of resin and having flexibility, a rubber waterproof cover, or a combination of these can be used. The cylindrical member 50 of this embodiment is a resin tube. As the material of the cylindrical member 50, a synthetic resin such as polypropylene, polyolefin, polyamide, polyester, etc. can be used.

[0048] The cylindrical member 50 has a first end 51 and a second end 52 in the axial direction of the cylindrical member 50. The first end 51 is an end provided at a position closest to the electrical devices M1 and M3 in the axial direction of the cylindrical member 50. The second end 52 is an end provided at a position closest to the electrical devices M2 and M4 in the axial direction of the cylindrical member 50.

[0049] The cross-sectional shape of the cylindrical member 50 can be formed into any shape. Figure 3 As shown, the cross-sectional shape of the cylindrical member 50 is formed into a flat shape longer in the Y-axis direction than in the Z-axis direction. The cross-sectional shape of the cylindrical member 50 of this embodiment is formed into an oval shape with a long side extending in the Y-axis direction and a short side extending in the Z-axis direction.

[0050] (Structure of Sheet 60) like Figure 2 As shown, the sheet 60 is, for example, provided in the middle of the length direction of the electric wire member 20. The sheet 60 has, for example, a longitudinal cross-sectional shape extending along the length direction of the electric wire member 20. The sheet 60 is, for example, provided such that a portion of the sheet 60 in the length direction is accommodated inside the cylindrical member 50, and the remaining portion of the sheet 60 is led out from the first end portion 51 of the cylindrical member 50 to the outside of the cylindrical member 50.

[0051] The sheet 60 is formed into a sheet or a tape, for example. The sheet 60 has self-welding properties. As the material of the sheet 60, for example, butyl rubber or silicone rubber can be used. As the sheet 60, for example, a sheet-shaped butyl sheet can be used. As the sheet 60, for example, a butyl tape can also be used.

[0052] like Figure 3As shown, the sheet 60 is provided in a manner to fill the gaps between the plurality of electric wires 31 and 41. The sheet 60 is provided, for example, to fill the gaps between the first electric wire member 30 and the second electric wire member 40. The sheet 60, for example, covers the outer periphery of each of the plurality of electric wires 31 over the entire circumference. The sheet 60, for example, is in close contact with the outer peripheral surface of each of the plurality of electric wires 31 over the entire circumference without a gap. The sheet 60 is provided, for example, to fill the gaps between the plurality of electric wires 31. The sheet 60, for example, covers the inner peripheral surface of the braided member 35 over the entire circumference. The sheet 60, for example, is provided in a manner to fill the gaps between each electric wire 31 and the braided member 35. The sheet 60, for example, covers the outer peripheral surface of the braided member 35 over the entire circumference. The sheet 60, for example, covers the outer periphery of the electric wire 41 over the entire circumference. The sheet 60, for example, covers the outer peripheral surface of the electric wire 41 over the entire circumference. The sheet 60 is provided, for example, to fill the gap between the braided member 35 and the electric wire 41. The sheet 60 is provided, for example, to enter the mesh 36 of the braided member 35. The sheet 60 is provided, for example, to fill the mesh 36. The sheet 60 is provided, for example, to enclose the braided member 35 in the middle portion in the longitudinal direction of the electric wire member 20. The sheet 60 functions as a waterproof member that prevents liquid such as water from penetrating into the interior of the cylindrical member 50 from the gap between the plurality of electric wires 31 and 41.

[0053] The sheet 60 is, for example, formed by integrating a plurality of sheets, specifically, a first sheet 61, a second sheet 62, and a third sheet 63. The first sheet 61 is, for example, formed in a manner to fill the gaps between the plurality of wires 31 inside the braided member 35 and to fill the gaps between the braided member 35 and the wires 31. The second sheet 62 is, for example, formed in a manner to cover the outer periphery of the braided member 35. The third sheet 63 is, for example, formed in a manner to fill the gaps between the second sheet 62 and the wires 41. The first sheet 61 and the second sheet 62 are, for example, continuously integrated through the mesh 36 of the braided member 35. The second sheet 62 and the third sheet 63 are continuously integrated. In addition, in Figure 3 In the figure, the first sheet 61, the second sheet 62, and the third sheet 63 are distinguished by solid lines in order to easily identify them. However, in reality, the interfaces between the first sheet 61, the second sheet 62, and the third sheet 63 may disappear or the boundaries may be unclear.

[0054] (Structure of the First Belt Member 70) like Figure 2As shown, the first tape member 70 is, for example, wound around the outer periphery of the sheet 60 and the outer periphery of the portion of the electric wire member 20 exposed from the sheet 60. The first tape member 70 is, for example, continuously wound over a range from the outer periphery of the electric wire member 20 exposed at one end in the longitudinal direction of the sheet 60 to the outer periphery of the electric wire member 20 exposed at the other end in the longitudinal direction of the sheet 60. The first tape member 70 is, for example, formed so as to cover the entire outer periphery of the sheet 60.

[0055] The first tape member 70 is spirally wound around the outer peripheral surfaces of the sheet 60 and the wire member 20, for example, with the adhesive layer facing radially inward. Figure 2 and Figure 3 Although detailed illustrations are omitted, the first belt member 70 is spirally wound on the outer peripheral surface of the sheet 60 and the wire member 20 in a manner that a portion of the first belt member 70 in the width direction overlaps, for example. That is, the first belt member 70 has an overlapping winding structure. Here, the so-called overlapping winding structure is a structure in which the belt member is wound in a spiral shape in a manner that predetermined portions in the width direction of the belt member overlap each other. In the overlapping winding structure, the ratio of the width of the later wound portion to the entire width of the first wound portion is called the overlapping amount. As overlapping winding, for example, half-overlapping winding in which half of the width of the belt member is overlapped can be used. In addition, the overlapping amount of the half-overlapping winding is one-half. The first belt member 70 of this embodiment has a half-overlapping winding structure.

[0056] The first belt member 70 is provided, for example, such that a portion of the first belt member 70 in the longitudinal direction is accommodated inside the tubular member 50, and the remaining portion of the first belt member 70 is drawn out from the first end portion 51 to the outside of the tubular member 50. The first belt member 70 has, for example, a function of protecting the sheet 60. The first belt member 70 has, for example, a function of covering the outer peripheral surface of the sheet 60 having adhesiveness.

[0057] The electric wire member 20 , the sheet 60 , and the first tape member 70 described above constitute the insertion member 15 to be inserted into the tubular member 50 . (Structure of the Second Belt Member 80) The second belt member 80 is wound around the outer periphery of the first end portion 51 of the cylindrical member 50 and the outer periphery of the first belt member 70 disposed outside the cylindrical member 50. That is, the second belt member 80 is wound around the outer periphery of the first end portion 51 and the outer peripheral surface of the first belt member 70 drawn out from the first end portion 51 to the outside of the cylindrical member 50. The second belt member 80 is formed so as to block the gap between the inner peripheral surface of the cylindrical member 50 and the outer peripheral surface of the first belt member 70. The second belt member 80 functions as a waterproof member that prevents liquid such as water from entering the inside of the cylindrical member 50 from the gap between the inner peripheral surface of the cylindrical member 50 and the outer peripheral surface of the first belt member 70. The second belt member 80 of this embodiment is also wound around the outer peripheral surface of the electric wire member 20 exposed from the first belt member 70. That is, the second belt member 80 of this embodiment is continuously wound around the range from the outer peripheral surface of the first end portion 51 to the outer peripheral surface of the electric wire member 20 exposed from the cylindrical member 50 and the first belt member 70. The second belt member 80 of the present embodiment is formed so as to cover the entire outer circumference of the first belt member 70 exposed from the cylindrical member 50 .

[0058] The second belt member 80 is, for example, spirally wound around the outer circumference of the cylindrical member 50, the first belt member 70, and the electric wire member 20 in a state where the adhesive layer faces radially inward. The second belt member 80 has, for example, an overlapping winding structure. The second belt member 80 has, for example, a semi-overlapping winding structure in most of the length direction of the second belt member 80. The second belt member 80 is, for example, wound multiple times in a manner that the entire width of the second belt member 80 overlaps in the winding and falling portion that is wound from the outer circumference of the cylindrical member 50 and falls on the outer circumference of the first belt member 70. That is, the second belt member 80 of the above-mentioned winding and falling portion is wound multiple times on the outer circumference of the first belt member 70 by overlapping winding with an overlapping amount of 1. In addition, in the overlapping winding structure with an overlapping amount of 1, the second belt member 80 is spirally wound around the outer circumference of the first belt member 70.

[0059] Here, a step is generated between the outer peripheral surface of the cylindrical member 50 and the outer peripheral surface of the first belt member 70, and therefore, due to the step, the second belt member 80 wound around the above-mentioned winding drop portion is easily wrinkled. When the second belt member 80 is wrinkled, a gap is generated between the outer peripheral surface of the first belt member 70 and the inner peripheral surface of the second belt member 80, and the waterproof property of the second belt member 80 is reduced. On the other hand, since the second belt member 80 is spirally wound multiple times at the above-mentioned winding drop portion, the generation of a gap between the outer peripheral surface of the first belt member 70 and the inner peripheral surface of the second belt member 80 can be appropriately suppressed.

[0060] like Figure 3As shown, the second band member 80 covers the outer peripheral surface of the cylindrical member 50 over the entire circumference. The second band member 80 covers the outer peripheral surface of the first band member 70 over the entire circumference. The second band member 80 is formed in a manner that the gap between the inner peripheral surface of the cylindrical member 50 and the outer peripheral surface of the first band member 70 is sealed over the entire circumference. Figure 3 In FIG. 1 , the overlapping and winding structure of the second belt member 80 is omitted.

[0061] (Structure of the Third Belt Member 90) like Figure 2 As shown, the third band member 90 is formed in a manner to close the gap between the inner peripheral surface of the cylindrical member 50 and the outer peripheral surface of the first band member 70 in cooperation with the second band member 80. The third band member 90 is wound around the outer periphery of the portion of the cylindrical member 50 exposed from the second band member 80, the outer periphery of the second band member 80, and the outer periphery of the portion of the wire member 20 exposed from the second band member 80. That is, the third band member 90 is continuously wound over the range from the outer peripheral surface of the cylindrical member 50 exposed at one end in the longitudinal direction of the second band member 80 to the outer peripheral surface of the wire member 20 exposed at the other end in the longitudinal direction of the second band member 80. The third band member 90 is formed in a manner to cover the entire outer periphery of the second band member 80.

[0062] The third tape member 90 is spirally wound around the outer peripheral surfaces of the cylindrical member 50, the second tape member 80, and the electric wire member 20, for example, with the adhesive layer facing radially inward. Figure 2 and Figure 3 Although detailed illustration is omitted, the third belt member 90 has, for example, an overlapping and winding structure. The third belt member 90 of this embodiment has a semi-overlapping and winding structure.

[0063] In this way, a waterproof structure is provided at the first end portion 51 of the cylindrical member 50, and the waterproof structure includes the sheet 60, the first belt member 70, the second belt member 80, and the third belt member 90. Figure 1 The second end portion 52 of the tubular member 50 shown may also be provided with a waterproof structure similar to the waterproof structure provided at the first end portion 51 .

[0064] (Manufacturing Method of Wire Harness 10) Next, a method for manufacturing the wire harness 10 will be described. First, if Figure 4 As shown in FIG. 1 , the electric wire member 20 having the first electric wire member 30 and the second electric wire member 40 is prepared. At this time, the sheet 60 before self-welding is attached to the middle portion of the electric wire member 20 in the longitudinal direction.

[0065] like Figure 5As shown, the sheet 60 before self-welding has a first sheet 61 surrounding the outer periphery of the plurality of electric wires 31 on the inner side of the braided member 35. The sheet 60 before self-welding has a second sheet 62 surrounding the outer periphery of the braided member 35. The sheet 60 before self-welding has a third sheet 63 surrounding the outer periphery of the second sheet 62 and the outer periphery of the electric wires 41. In addition, before self-welding, the gaps between the plurality of electric wires 31, the gaps between the electric wires 31 and the braided member 35, and the gaps between the braided member 35 and the electric wires 41 are not filled by the sheet 60.

[0066] Next, the first sheet 61, the second sheet 62, and the third sheet 63 are pressed radially inward, so that the first sheet 61, the second sheet 62, and the third sheet 63 are integrated by self-welding. Figure 3 The sheet 60 shown. That is, the sheet 60 can be formed to fill the gaps between the plurality of wires 31, the gaps between the wires 31 and the braided member 35, and the gaps between the braided member 35 and the wires 41. For example, when the second sheet 62 is pressed toward the braided member 35, the second sheet 62 enters the mesh 36 of the braided member 35, and the second sheet 62 is integrated with the first sheet 61 through the mesh 36. In addition, in this process, the first sheet 61, the second sheet 62, and the third sheet 63 may be vibrated, or the first sheet 61, the second sheet 62, and the third sheet 63 may be heated.

[0067] Then, in Figure 6 In the process shown, the first tape member 70 is wound around the outer peripheral surface of the wire member 20 and the outer peripheral surface of the sheet 60. When the first tape member 70 is wound, for example, the first tape member 70 is drawn out from the spiral structure, and the drawn first tape member 70 is spirally wound around the outer peripheral surface of the wire member 20 and the sheet 60. Figure 7 As shown, the first band member 70 of the present embodiment is continuously half-overlapped and wound from the outer peripheral surface of the wire member 20 exposed at one end in the longitudinal direction of the sheet 60 to the outer peripheral surface of the wire member 20 exposed at the other end in the longitudinal direction of the sheet 60. Through the above steps, the insertion member 15 having the wire member 20, the sheet 60 and the first band member 70 is formed.

[0068] Then, in Figure 8 In the process shown, the insertion member 15 is inserted into the interior of the cylindrical member 50. The insertion member 15 is inserted into the cylindrical member 50 in such a manner that a portion of the sheet 60 and the first belt member 70 in the longitudinal direction are inserted into the interior of the cylindrical member 50. In the structure of this process, a gap is generated between the inner peripheral surface of the cylindrical member 50 and the outer peripheral surface of the insertion member 15, specifically, the outer peripheral surface of the first belt member 70.

[0069] Next, the second belt member 80 is wound around the outer circumference of the first end portion 51 of the cylindrical member 50 and the outer circumference of the insertion member 15 that is led out from the first end portion 51 to the outside of the cylindrical member 50. The second belt member 80 is spirally wound around the outer circumference of the cylindrical member 50 and the insertion member 15 along the travel direction P1, and the travel direction P1 is along the length direction of the wire member 20. That is, the second belt member 80 is spirally wound around the outer circumference of the cylindrical member 50 and the insertion member 15 in a manner of advancing from the starting end side of the travel direction P1 (the cylindrical member 50 side on the right side in the figure) toward the terminal side of the travel direction P1 (the left side in the figure). Fig. 9 As shown, the second belt member 80 of the present embodiment is continuously overlapped and wound to the range from the outer peripheral surface of the first end portion 51 of the cylindrical member 50 to the outer peripheral surface of the wire member 20 exposed from the cylindrical member 50 and the first belt member 70. Through this step, the gap between the inner peripheral surface of the cylindrical member 50 and the outer peripheral surface of the insertion member 15 is blocked by the second belt member 80.

[0070] Then, in Fig.10 In the process shown, the third tape member 90 is wound around the outer peripheral surface of the cylindrical member 50, the outer peripheral surface of the second tape member 80, and the outer peripheral surface of the electric wire member 20 exposed from the second tape member 80. Through the above process, the wire harness 10 of the present embodiment can be manufactured.

[0071] Next, the effects of this embodiment will be described. (1-1) The wire harness 10 includes: a cylindrical member 50; an electric wire member 20 passing through the cylindrical member 50; a sheet 60 having self-welding properties and wound around the outer periphery of the electric wire member 20; and a first belt member 70 wound around the outer periphery of the sheet 60. The wire harness 10 includes a second belt member 80 wound around the outer periphery of the first end portion 51 in the axial direction of the cylindrical member 50 and the outer periphery of the first belt member 70 disposed outside the cylindrical member 50. The sheet 60 is formed so as to fill the gaps between the plurality of electric wires 31 and 41 of the electric wire member 20.

[0072] According to this structure, the gaps between the plurality of electric wires 31 and 41 are buried by the sheet material 60 having self-welding properties. Thus, it is possible to suppress liquid such as water from penetrating into the interior of the cylindrical member 50 through the gaps between the plurality of electric wires 31 and 41. In addition, the second belt member 80 is wound around the outer periphery of the first end portion 51 of the cylindrical member 50 and the outer periphery of the first belt member 70 disposed outside the cylindrical member 50. The second belt member 80 can block the gap between the inner peripheral surface of the cylindrical member 50 and the outer peripheral surface of the first belt member 70. Therefore, it is possible to suppress liquid from penetrating into the interior of the cylindrical member 50 through the gap between the inner peripheral surface of the cylindrical member 50 and the outer peripheral surface of the first belt member 70. Furthermore, the sheet material 60 functioning as a waterproof member is a structure wound around the outer periphery of the electric wire member 20, and the second belt member 80 functioning as a waterproof member is a structure wound around the outer periphery of the cylindrical member 50 and the outer periphery of the first belt member 70. Therefore, compared with the conventional structure in which the grommet is provided outside the outer member, the size of the entire wire harness 10 can be suppressed from being increased. Therefore, the wire harness 10 has waterproof performance and can be appropriately suppressed from being increased in size.

[0073] (1-2) The second belt member 80 is wound around the outer periphery of the first end portion 51 of the cylindrical member 50, the outer periphery of the first belt member 70 exposed from the cylindrical member 50, and the outer periphery of the electric wire member 20 exposed from the cylindrical member 50 and the first belt member 70. Thus, the entire outer periphery of the first belt member 70 exposed from the cylindrical member 50 is covered by the second belt member 80, and a labyrinth structure is formed between the first belt member 70 and the second belt member 80. Therefore, the waterproof property of the second belt member 80 can be improved.

[0074] (1-3) The third belt member 90 is wound around the outer periphery of the cylindrical member 50 exposed from one end of the second belt member 80 to the outer periphery of the electric wire member 20 exposed from the other end of the second belt member 80. As a result, the entire outer periphery of the second belt member 80 is covered by the third belt member 90, and a labyrinth structure is formed between the second belt member 80 and the third belt member 90. Therefore, the second belt member 80 and the third belt member 90 can appropriately suppress the liquid from penetrating into the inside of the cylindrical member 50 through the gap between the inner peripheral surface of the cylindrical member 50 and the outer peripheral surface of the first belt member 70.

[0075] (1-4) The first tape member 70 is wound around the sheet 60 and the electric wire member 20 so as to cover the entire outer circumference of the sheet 60. The sheet 60 can be appropriately protected by the first tape member 70. In addition, the outer circumferential surface of the sheet 60, which serves as the adhesive surface, can be covered by the first tape member 70, so that the workability when inserting the electric wire member 20 attached with the sheet 60 into the inside of the cylindrical member 50 can be improved.

[0076] (1-5) The first sheet 61 is used to fill the gaps between the plurality of wires 31 and the gaps between the braided member 35 and the wires 31. In addition, the second sheet 62 is used to cover the outer periphery of the braided member 35. Furthermore, the third sheet 63 is used to fill the gaps between the wires 41 and the second sheet 62. In addition, the first sheet 61, the second sheet 62, and the third sheet 63 are integrated to form the sheet 60. By using these first sheet 61, the second sheet 62, and the third sheet 63, it is possible to suppress the liquid from penetrating into the interior of the cylindrical member 50 through the gaps between the plurality of wires 31, the gaps between the braided member 35 and the wires 31, and the gaps between the wires 41 and the second sheet 62.

[0077] (1-6) The cross-sectional shape of the cylindrical member 50 is formed into a flat shape that is longer in the Y-axis direction (first direction) than in the Z-axis direction (second direction) in which the plurality of electric wires 31 and 41 are arranged. Therefore, compared with a case where the dimension along the Y-axis direction and the dimension along the Z-axis direction in the cross-sectional shape of the cylindrical member 50 are equal to each other, the cylindrical member 50 can be miniaturized in the Z-axis direction.

[0078] (Second embodiment) In addition, in this embodiment, the difference from the first embodiment is mainly described, and sometimes the same reference numerals are given to the same or corresponding structures as the first embodiment, and part or all of the description of other structures is omitted.

[0079] (Structure of the wiring harness 10A) like Fig.11 As shown, the wire harness 10A includes: a cylindrical member 50; an insertion member 15A inserted into the inside of the cylindrical member 50; and a second belt member 80A wound around the outer periphery of the cylindrical member 50 and the outer periphery of the portion of the insertion member 15A exposed from the cylindrical member 50. The wire harness 10A includes, for example, a third belt member 90A covering the entire outer periphery of the second belt member 80A. The insertion member 15A includes a wire member 20, a sheet 60, a first belt member 70, and a cylindrical retainer 100 fitted inside the first end 51 of the cylindrical member 50. The second belt member 80A and the third belt member 90A are, for example, a base material and an adhesive tape having an adhesive layer laminated on one side of the base material.

[0080] The holding body 100 has a first end portion 101 on the holding body side and a second end portion 102 on the holding body side in the axial direction of the holding body 100. The holding body 100 has a housing portion 103, and the electric wire member 20 wound with the sheet 60 and the first belt member 70 passes through the housing portion 103. The holding body 100 is provided, for example, such that a portion of the holding body 100 in the axial direction is housed inside the cylindrical member 50, and the remaining portion of the holding body 100 is arranged outside the cylindrical member 50. In the present embodiment, the first end portion 101 on the holding body side is arranged inside the cylindrical member 50, and the second end portion 102 on the holding body side is arranged outside the cylindrical member 50.

[0081] The friction coefficient of the outer peripheral surface of the retaining body 100 is lower than the friction coefficient of the outer peripheral surface of the first belt member 70. The retaining body 100 is made of metal or resin, for example. The retaining body 100 of this embodiment is made of resin. As the material of the retaining body 100, for example, a synthetic resin with excellent self-lubricating properties can be used. As the material of the retaining body 100, for example, a synthetic resin such as polypropylene, polyamide, and polyacetal can be used. The retaining body 100 can be manufactured by a known manufacturing method such as extrusion molding and injection molding.

[0082] like Fig.12 As shown, the storage portion 103 of the retaining body 100 has a first storage portion 104 and a second storage portion 105. The first storage portion 104 and the second storage portion 105 are formed in a mutually connected manner. The first storage portion 104 partially stores the first wire member 30 wound with the sheet 60 and the first belt member 70. The second storage portion 105 partially stores the second wire member 40 wound with the sheet 60 and the first belt member 70. Fig.11 As shown, the holding body 100 of the present embodiment accommodates the sheet material 60 and a portion of the length direction of the first belt member 70 inside. In other words, the first belt member 70 of the present embodiment is arranged such that a portion of the length direction of the first belt member 70 is accommodated inside the holding body 100, and the remaining portion of the first belt member 70 is led out of the holding body side second end portion 102 to the outside of the holding body 100. The sheet material 60 of the present embodiment is arranged such that a portion of the length direction of the sheet material 60 is accommodated inside the holding body 100, and the remaining portion of the sheet material 60 is led out of the holding body side second end portion 102 to the outside of the holding body 100.

[0083] like Fig.12 and Fig.13 As shown, the retaining body 100 includes, for example, a first split body 110A and a second split body 110B which is a separate component from the first split body 110A. The first split body 110A includes, for example, a groove 114A, a recess 115A, and a partition 116A. The second split body 110B includes, for example, a groove 114B, a recess 115B, and a partition 116B. Fig.12As shown, the retaining body 100 is formed into a cylindrical shape that surrounds the electric wire member 20, the sheet 60, and the first belt member 70 by overlapping the first split body 110A and the second split body 110B. The first split body 110A and the second split body 110B are overlapped in a manner that the grooves 114A and the grooves 114B are connected to each other, and the recesses 115A and the recesses 115B are connected to each other. In the state where the first split body 110A and the second split body 110B are overlapped, the first storage portion 104 is formed by the grooves 114A and the grooves 114B, and the second storage portion 105 is formed by the recesses 115A and the recesses 115B. Here, the first split body 110A and the second split body 110B have, for example, the same structure as each other. Therefore, in the following description, the structure of the first split body 110A is described in detail, and the structure of the second split body 110B is omitted. Specifically, regarding the structure of the second divided body 110B, reference numerals are given in which the last “A” of the reference numerals of the corresponding structures of the first divided body 110A is changed to “B”, thereby omitting redundant description.

[0084] (Structure of the First Division Body 110A) like Fig.13 As shown, the first split body 110A is formed as a half-split cylinder as a whole. The groove 114A and the recess 115A are each formed in a manner of being recessed from the surface opposite to the second split body 110B toward the direction away from the second split body 110B. The groove 114A and the recess 115A each extend, for example, along the axial direction of the retaining body 100 over the entire length of the axial direction of the retaining body 100.

[0085] like Fig.12 As shown, the inner surface of the groove portion 114A is formed, for example, in a shape corresponding to the outer peripheral surface of the first electric wire member 30. The cross-sectional shape of the groove portion 114A of this embodiment is formed in a semi-long circle. The inner surface of the groove portion 114A is formed, for example, in a manner of being in close contact with the outer peripheral surface of the first belt member 70 wound around the outer periphery of the sheet 60 covering the outer periphery of the first electric wire member 30. The inner surface of the groove portion 114A is formed, for example, in a manner of being in close contact with the outer peripheral surface of the first belt member 70 over the entire circumference of the first housing portion 104.

[0086] The inner surface of the recess 115A is formed, for example, in a shape corresponding to the outer peripheral surface of the second electric wire member 40. The cross-sectional shape of the recess 115A in this embodiment is formed in a semicircular shape. The inner surface of the recess 115A is formed, for example, in a manner closely contacting the outer peripheral surface of the first belt member 70 wound around the outer periphery of the sheet 60 covering the outer periphery of the second electric wire member 40. The inner surface of the recess 115A is formed, for example, in a manner closely contacting the outer peripheral surface of the first belt member 70 over the entire circumference of the second housing portion 105.

[0087] The partition 116A is provided, for example, in a manner that partially partitions the groove 114A and the recess 115A. A portion of the partition 116A is formed by the inner surface of the groove 114A, and another portion of the partition 116A is formed by the inner surface of the recess 115A. The partition 116A is provided in a manner that is opposed to the partition 116B in the Z-axis direction. The top end surface of the partition 116A and the top end surface of the partition 116B are provided, for example, in a manner that is not in contact with each other. Between the top end surface of the partition 116A and the top end surface of the partition 116B, for example, a sheet 60 that fills the gap between the first wire component 30 and the second wire component 40 is provided. The top end surfaces of the partition 116A and the partition 116B are formed, for example, in a manner that is in close contact with the outer peripheral surface of the first belt component 70.

[0088] like Fig.11 As shown, the first end portion 101 of the retaining body 100 is formed in a manner that becomes thinner as it moves from the second end portion 102 of the retaining body toward the opening end of the first end portion 101 of the retaining body. The outer peripheral surface of the first end portion 101 of the retaining body has an inclined surface 121 that inclines toward the radial inner side of the retaining body 100 as it moves from the second end portion 102 of the retaining body toward the opening end of the first end portion 101 of the retaining body. Fig.13 As shown, the inclined surface 121 is formed over the entire circumference of the holding body 100 , for example.

[0089] like Fig.11 As shown, the second end portion 102 on the retaining body side has, for example, an engaging portion 122 that engages with the end face of the cylindrical member 50 in the axial direction of the cylindrical member 50. The engaging portion 122 is formed in a manner that protrudes from the outer peripheral surface of the second end portion 102 on the retaining body side toward the radial outer side of the retaining body 100. The engaging portion 122 has a protruding top end surface 123 disposed on the radial outer side. The protruding top end surface 123 is formed, for example, so as to be coplanar with the outer peripheral surface of the first end portion 51 of the cylindrical member 50 when the retaining body 100 is engaged with the inner side of the cylindrical member 50. As shown in FIG. Fig.13 As shown, the engaging portion 122 is formed over the entire circumference of the holding body 100 , for example.

[0090] The cross-sectional shape of the retaining body 100 along the outer peripheral surface can be formed into any shape. Fig.12 As shown, the cross-sectional shape of the holding body 100 along the outer peripheral surface is, for example, the same as the cross-sectional shape of the cylindrical member 50 along the inner peripheral surface. The cross-sectional shape of the holding body 100 along the outer peripheral surface is, for example, formed into a flat shape that is longer in the Y-axis direction than in the Z-axis direction. The cross-sectional shape of the holding body 100 along the outer peripheral surface of the present embodiment is formed into an oblong shape whose long side extends in the Y-axis direction and whose short side extends in the Z-axis direction.

[0091] like Fig.11As shown, the holder 100 is inserted into the interior of the cylindrical member 50 from the first end portion 101 on the holder side in the axial direction of the holder 100, for example, with the sheet 60 and the first belt member 70 stored in the storage portion 103. At this time, the holder 100 is positioned in the axial direction of the cylindrical member 50 by the engagement portion 122 of the holder 100 engaging with the end face of the cylindrical member 50 in the axial direction.

[0092] (Structure of the Second Belt Member 80A) The second band member 80A is wound around, for example, the outer periphery of the first end portion 51 of the cylindrical member 50, the outer periphery of the portion of the holder 100 disposed outside the cylindrical member 50, and the outer periphery of the portion of the first band member 70 exposed from the holder 100. That is, the second band member 80A is wound around the outer peripheral surface of the first end portion 51, the protruding top end surface 123 of the holder 100 disposed outside the cylindrical member 50 from the first end portion 51, and the outer peripheral surface of the first band member 70 exposed from the holder 100. The second band member 80A is formed so as to block the gap between the cylindrical member 50 and the holder 100. The second band member 80A is formed so as to block the gap between the end surface of the cylindrical member 50 in the axial direction and the engaging portion 122, and the gap between the inner peripheral surface of the cylindrical member 50 and the outer peripheral surface of the holder 100. The second band member 80A is formed so as to block the gap between the inner peripheral surface of the holder 100 and the outer peripheral surface of the first band member 70. The second belt member 80A of the present embodiment is also wound around the outer peripheral surface of the portion of the electric wire member 20 exposed from the first belt member 70. That is, the second belt member 80A of the present embodiment is continuously wound over the range from the outer peripheral surface of the first end portion 51 to the outer peripheral surface of the electric wire member 20 exposed from the cylindrical member 50, the retaining body 100, and the first belt member 70. The second belt member 80A of the present embodiment is formed so as to cover the entire outer periphery of the first belt member 70 exposed from the cylindrical member 50 and the retaining body 100.

[0093] The second belt member 80A has, for example, an overlapping winding structure. The second belt member 80A has, for example, a semi-overlapping winding structure in most of the length direction of the second belt member 80A. The second belt member 80A is wound multiple times in a manner that the entire width of the second belt member 80A overlaps, for example, in the winding and falling portion from the protruding top end surface 123 of the retainer 100 to the outer peripheral surface of the first belt member 70. That is, the second belt member 80A in the above-mentioned winding and falling portion is wound multiple times on the outer peripheral surface of the first belt member 70 by overlapping winding with an overlap amount of 1.

[0094] (Structure of the Third Belt Member 90A) like Fig.11As shown, the third belt member 90A is formed in a manner that cooperates with the second belt member 80A to block the gap between the cylindrical member 50 and the retaining body 100 and the gap between the inner peripheral surface of the retaining body 100 and the outer peripheral surface of the first belt member 70. The third belt member 90A is wound around the outer periphery of the portion of the cylindrical member 50 exposed from the second belt member 80A, the outer periphery of the second belt member 80A, and the outer periphery of the portion of the wire member 20 exposed from the second belt member 80A. The third belt member 90A is continuously wound from the outer peripheral surface of the cylindrical member 50 exposed at one end of the length direction of the second belt member 80A to the outer peripheral surface of the wire member 20 exposed at the other end of the length direction of the second belt member 80A. The third belt member 90A has, for example, an overlapping winding structure. The third belt member 90A of this embodiment has a semi-overlapping winding structure.

[0095] According to the embodiment described above, in addition to the same effects as (1-3) to (1-6) of the first embodiment, the following effects can be achieved. (2-1) The wire harness 10A includes: a cylindrical member 50; an electric wire member 20 passing through the cylindrical member 50; a sheet 60 having self-welding properties and wound around the outer periphery of the electric wire member 20; and a first belt member 70 wound around the outer periphery of the sheet 60. The wire harness 10A includes a cylindrical retainer 100, the retainer 100 is fitted inside the first end portion 51 of the cylindrical member 50 in the axial direction, and surrounds the outer periphery of the first belt member 70. The wire harness 10A includes a second belt member 80A, and the second belt member 80A is wound around the outer periphery of the first end portion 51, the outer periphery of the portion of the retainer 100 disposed outside the cylindrical member 50, and the outer periphery of the portion of the first belt member 70 exposed from the retainer 100. The sheet 60 is formed so as to fill the gaps between the plurality of electric wires 31 and 41 of the electric wire member 20. The friction coefficient of the outer peripheral surface of the retainer 100 is lower than the friction coefficient of the outer peripheral surface of the first belt member 70.

[0096] According to this structure, the gaps between the plurality of electric wires 31 and 41 are buried by the sheet material 60 having self-welding properties. Thus, it is possible to suppress liquid such as water from penetrating into the interior of the cylindrical member 50 through the gaps between the plurality of electric wires 31 and 41. In addition, the second belt member 80A is wound around the outer periphery of the first end portion 51 of the cylindrical member 50, the outer periphery of the portion of the retaining body 100 disposed outside the cylindrical member 50, and the outer periphery of the portion of the first belt member 70 exposed from the retaining body 100. The second belt member 80A can block the gap between the cylindrical member 50 and the retaining body 100, and can block the gap between the inner peripheral surface of the retaining body 100 and the outer peripheral surface of the first belt member 70. Therefore, it is possible to suppress liquid from penetrating into the interior of the cylindrical member 50 through the gap between the cylindrical member 50 and the retaining body 100 and the gap between the inner peripheral surface of the retaining body 100 and the outer peripheral surface of the first belt member 70. In addition, the sheet 60 that functions as a waterproof member is wound around the outer periphery of the electric wire member 20, and the second belt member 80A that functions as a waterproof member is wound around the outer periphery of the cylindrical member 50. Therefore, compared with the conventional structure in which a wire sheath is provided on the outer side of the outer member, the overall size of the wire harness 10A can be suppressed from being enlarged. Therefore, the wire harness 10A can be appropriately suppressed from being enlarged while having waterproof performance.

[0097] (2-2) Furthermore, the friction coefficient of the outer peripheral surface of the retaining body 100 surrounding the outer periphery of the first belt member 70 is lower than the friction coefficient of the outer peripheral surface of the first belt member 70. Thus, when the retaining body 100 is inserted into the inside of the cylindrical member 50, the retaining body 100 can slide easily relative to the inner peripheral surface of the cylindrical member 50. Therefore, the workability when inserting the retaining body 100 into the inside of the cylindrical member 50 can be improved.

[0098] (2-3) The first end portion 101 of the holder 100 that is first inserted into the tubular member 50 is formed into a tapered shape. This makes it easier to insert the holder 100 into the tubular member 50. Therefore, the workability when inserting the holder 100 into the tubular member 50 can be improved.

[0099] (2-4) The engaging portion 122 that engages with the end face in the axial direction of the tubular member 50 is provided at the second end portion 102 on the retaining body side. Therefore, when the retaining body 100 is inserted into the tubular member 50, the retaining body 100 can be easily positioned in the axial direction of the tubular member 50. Thus, the workability when inserting the retaining body 100 into the tubular member 50 can be improved.

[0100] (2-5) The retaining body 100 is formed into a cylindrical shape in which the first band member 70 is surrounded by the first split body 110A and the second split body 110B. Thus, although the retaining body 100 is formed into a cylindrical shape, the retaining body 100 is divided into the first split body 110A and the second split body 110B, and the retaining body 100 can be attached to the electric wire member 20 or the like later. That is, the retaining body 100 is divided into the first split body 110A and the second split body 110B, and the retaining body 100 can be attached to the electric wire member 20 or the like after the sheet 60 and the first band member 70 are attached to the outer periphery of the electric wire member 20, for example. As a result, the assembly workability of the wire harness 10A can be improved.

[0101] (Other embodiments) The above-mentioned embodiments can be implemented as the following modifications. The above-mentioned embodiments and the following modifications can be implemented in combination with each other within the scope of no technical contradiction.

[0102] ·like Fig.14 As shown in the figure, the retaining body 100 may be provided in a manner that surrounds the entire periphery of the first belt member 70. That is, the retaining body 100 may be provided in a manner that surrounds the periphery of the first belt member 70 over the entire length of the first belt member 70 in the longitudinal direction. In the insertion member 15A of this modification, the first belt member 70 is not exposed to the outside of the retaining body 100. The second belt member 80A of this modification is wound around the periphery of the first end portion 51 of the cylindrical member 50, the protruding top end surface 123 of the retaining body 100 exposed from the cylindrical member 50, and the periphery of the electric wire member 20 exposed from the cylindrical member 50 and the retaining body 100.

For example, the second belt members 80, 80A may not have a structure of overlapping winding with an overlap amount of 1 in the entire length in the length direction.

[0108] The winding method of the third belt member 90, 90A in the above-mentioned embodiments is not particularly limited. For example, similar to the second belt member 80, 80A, the third belt member 90, 90A may be wound in an overlapping manner with an overlap amount of 1 in a portion of the length direction of the third belt member 90, 90A.

[0109] The third belt members 90 and 90A in the above-mentioned embodiments may be omitted. In the second embodiment, the protruding top end surface 123 of the engaging portion 122 of the retaining body 100 is formed to be coplanar with the outer peripheral surface of the cylindrical member 50, but the present invention is not limited thereto. For example, the protruding top end surface 123 may be arranged radially outward from the outer peripheral surface of the cylindrical member 50, or radially inward from the outer peripheral surface of the cylindrical member 50.

[0110] The engaging portion 122 of the holding body 100 in the second embodiment may be omitted. The inclined surface 121 of the holding body 100 in the second embodiment may be omitted.

[0111] In the holder 100 of the second embodiment, the first split body 110A and the second split body 110B are formed of separate components, but the present invention is not limited thereto. For example, the first split body 110A and the second split body 110B may be integrally formed by a hinge or the like.

[0112] The sheet 60 of each of the above embodiments is formed by integrating three sheets, specifically, the first sheet 61, the second sheet 62, and the third sheet 63, but the number of sheets before integration is not particularly limited. For example, four or more sheets may be integrated to form the sheet 60. In addition, two sheets may be integrated to form the sheet 60.

[0113] The structure of the wire component 20 in the above-mentioned embodiments is not particularly limited. For example, in the first wire component 30 in the above-mentioned embodiments, the electromagnetic shielding component is embodied as a braided component 35, but the electromagnetic shielding component may also be embodied as a metal foil. For example, the electromagnetic shielding component of the first wire component 30 may be omitted. For example, the number of wires 31 of the first wire component 30 may be three or more. For example, the number of wires 41 of the second wire component 40 may be two or more.
