<Base Member>

The base member 30 is disposed between the door panel 12 and the door trim 16 in the door 10. The base member 30 is a member planarly extending on the door panel 12 and the door trim 16. The base member 30 is a flat component extending over an area substantially equal to or larger than the opening 15. The base member 30 is attached to the opening 15 of the inner panel 14 to cover the opening 15. Accordingly, the base member 30 can partition the inner side and outer side of the vehicle. The base member 30 is attached to the opening 15 of the inner panel 14, and the attaching state is retained by a screwing structure or a locking structure, for example. For example, when a part of a peripheral portion of the base member 30 overlapped with the inner panel 14 is screwed to the inner panel 14 using a screw, for example, a gap therebetween can be practicably covered.

A space is formed between the outer panel 13 and the inner panel 14 and between the outer panel 13 and the base member 30 while the base member 30 is attached to the inner panel 14. A window of the door 10 can be housed in this space. A window exposed to a rainwater environment is housed in the space, and a slit-like opening through which the window goes in and out is formed on an upper side of the space. Thus, the space is a space which water may enter. The space is a space which may be connected to an outer space, thus is also a space which a wind noise, for example, may enter from outside. The base member 30 is provided as a member for completely partitioning a vehicle interior space and an outer space with the inner panel 14.

More specifically, the base member 30 is a molded component made of resin or metal, for example. The base member 30 includes a main plate 32.

Both surfaces of the main plate 32 facing the inner side and the outer side of the vehicle may be attachment surfaces.

The attachment surface 33 may be flat. The attachment surface 33 may be formed into a concave-convex shape. A part of the attachment surface 33 covering the opening 15 may be concaved to the outer side of the vehicle more than a part thereof covering a periphery of the opening 15 to enter the opening 15. The plurality of wiring members 40 are disposed on the attachment surface 33. A part of the attachment surface 33 following a route along which the wiring member 40 is disposed may be flat. The part following the route along which the wiring member 40 is disposed may have a concave-convex shape.

<Wiring Member>

The wiring member 40 is connected to the apparatus 18. The wiring member 40 is a wiring for supplying electrical power to the apparatus 18 or transmitting a signal between the apparatus 18 and a vehicle side apparatus. Herein, the wiring member 40 includes a plurality of electrical wires 41, 42, and 43. The electrical wires 41, 42, and 43 may be a covering wire. The covering wire includes a core wire and a covering layer around the core wire. The electrical wires 41, 42, and 43 may be a single-core wire, or may also be a multicore wire. The wiring member 40 may include an optical fiber cable.

The plurality of electrical wires 41, 42, and 43 include a first electrical wire 41, a second electrical wire 42, and a third electrical wire 43. The first electrical wire 41, the second electrical wire 42, and the third electrical wire 43 are connected to different apparatuses 18, respectively. The first electrical wire 41, the second electrical wire 42, and the third electrical wire 43 includes one or a plurality of electrical wires, respectively, and are set in accordance with the apparatus 18.

The first electrical wire 41, the second electrical wire 42, and the third electrical wire 43 are collected in a parallel state on each one end side. One end portions of the plurality of electrical wires 41, 42, and 43 extend from a side of a hinge of the door 10 in a collected state and are led to an inner side of a vehicle body. One end portions of the plurality of electrical wires 41, 42, and 43 are assumed to be connected to the other connector provided in one end portion of a wiring in the vehicle body via a common connector, for example. Accordingly, an electrical power supply to the apparatus 18 and communication between the apparatus 18 and a vehicle side apparatus can be performed via the wiring member 40. When an electrical control unit is provided in the door 10, a wiring member connecting the electrical control unit and a wiring in the vehicle body and a wiring member connecting the electrical control unit and the apparatus 18 are preferably provided as the wiring member 40.

The other end portions of the first electrical wire 41, the second electrical wire 42, and the third electrical wire 43 are connected to the apparatus 18. Herein, wiring side connectors C1 are attached to the other end portions of the first electrical wire 41, the second electrical wire 42, and the third electrical wire 43, respectively. An apparatus side connector C2 is provided in the apparatus 18. The wiring side connector C1 and the apparatus side connector C2 are connected to each other. The electrical wires 41, 42, and 43 and the apparatus 18 may be connected to each other without an intervention of the connectors C1 and C2.

The plurality of electrical wires 41, 42, and 43 extends on the base member 30 while being collected from one end side. The plurality of electrical wires 41, 42, and 43 are branched into the first electrical wire 41, the second electrical wire 42, and the third electrical wire 43 on the base member 30. In the example illustrated in FIG. 1, the first electrical wire 41, the second electrical wire 42, and the third electrical wire 43 are branched at one branch position on the base member 30. The first electrical wire 41, the second electrical wire 42, and the third electrical wire 43 may be branched at different positions on the base member 30. For example, the first electrical wire 41 and the second electrical wire 42 may be branched at a first branch position, and the first electrical wire 41, the second electrical wire 42, and the third electrical wire 43 may be branched at a second branch position closer to a door hinge than the first branch position. The first electrical wire 41, the second electrical wire 42, and the third electrical wire 43 extend from the branch position to the apparatus 18 along a route in accordance with a position of the apparatus 18. Any route is applicable as a route from the branch position to the apparatus 18, however, a route as short as possible is preferable. A portion where the plurality of electrical wires 41, 42, and 43 are collected is a main wire part. Portions where the first electrical wire 41, the second electrical wire 42, and the third electrical wire 43 separately extend after the plurality of electrical wires 41, 42, and 43 are branched are branch wire parts.

<Holding Member>

Herein, the branch wire part is provided with a holding member 50A, and the main wire part is provided with a holding member 50B. When the holding members 50A and 50B need not be particularly distinguished, they are simply referred to as the holding member 50. The holding member 50 is described in detail with reference to FIG. 2 to FIG. 8. FIG. 2 is an enlarged perspective view of a region A1 in FIG. 1. FIG. 3 is a schematic cross-sectional view of the region A1 in FIG. 1. FIG. 3 is a vertical cross-sectional view cut along a plane perpendicular to the attachment surface 33 and parallel to an extension direction of the wiring member 40. FIG. 4 and FIG. 5 are explanation diagrams each illustrating a protection member attached to the wiring member 40. FIG. 6 is an enlarged plan view of a region A2 in FIG. 1. FIG. 7 is a schematic enlarged front view of the region A2 in FIG. 1. FIG. 8 is an explanation diagram illustrating a protection member attached to the wiring member 40.

The holding member 50 keeps the plurality of wiring members 40 in a state of being arranged side by side. The holding member 50 includes at least one sheet portion 52. At least one hole 56 is formed in the sheet portion 52. The plurality of wiring members 40 pass through the hole 56 and are held in a state of being arranged side by side.

Any material and structure may be applied to those of the sheet portion 52. Applicable as the material thereof is a flexible resin such as soft polyvinyl chloride (PVC) or rigid resin such as rigid PVC or polypropylene (PP). With regard to the structure, the sheet portion 52 may be a sheet having a porous structure such as a non-woven cloth or a foam sheet or a sheet with an evenly filled cross-sectional surface (also referred to as a non-foam sheet or a solid sheet, for example).

The sheet portion 52 may be a soft member (flexible member). The sheet portion 52 may be a hard member (member having high rigidity). The sheet portion 52 may be a member having higher rigidity than covering layers of the electrical wires 41, 42, and 43. Hardness may be different between a part of the sheet portion 52 and the other part thereof. The hardness of the sheet portion 52 is determined by a material and a structure, for example. For example, with regard to the material, a sheet made up of flexible resin as a material tends to be softer than a sheet made up of rigid resin as a material. For example, with regard to the structure, a porous sheet tends to be softer than a solid sheet.

Herein, the plurality of holding members 50 are formed to be connected in a longitudinal direction of the wiring member 40. The holding member 50 includes the plurality of sheet portions 52. When the plurality of sheet portions 52 are connected to constitute the holding member 50, it is preferable that the sheet portions 52 are not broken but can be bended. Described herein is an example that the holding member 50 includes four sheet portions 52. The number of the sheet portions 52 is not limited thereto, however, the number thereof may be two, three, or five or more. The number of the sheet portions 52 may be an odd number or an even number. When the number of the sheet portions 52 is an odd number, an edge portion 51a on one end side of the protection member along the extension direction of the wiring member 40 and an edge portion 51b on the other end side thereof are directed to directions opposite to each other. When the number of the sheet portions 52 is an even number, the edge portion 51a on one end side of the holding member 50 and an edge portion 51b on the other end side thereof are directed to the same direction.

The holes 56 in the plurality of sheet portions 52 are formed in positions so that the corresponding holes 56 can be overlapped with each other when the plurality of sheet portions 52 are bended at a predetermined position and overlapped with each other. The predetermined position corresponds to a connection portion of the plurality of sheet portions 52. A fold line CR is formed in the predetermined position in the holding member 50.

When the holding member 50 is a hard member such as a PP sheet, the fold line CR is normally made when the holding member 50 is bended. When the holding member 50 is a soft member such as a non-woven cloth, there is a case where the fold line CR is not made when the holding member 50 is beaded. In this case, the fold line CR may be made by pressing a bended portion while the holding member 50 is bended. The fold line CR is formed in the holding member 50, thus the plurality of sheet portions 52 are kept in a bended state even when they are developed.

The sheet portion 52 is joined to the attachment surface 33. The hole 56 is formed in an intermediate region along a width direction of the sheet portion 52. Both side regions of the sheet portion 52 are joined to the attachment surface 33. Herein, the sheet portion 52 includes a body 55 and a fixing piece 58. The body 55 is a part where the hole 56 is formed. Any shape is applicable as a shape of the body 55, however, preferable is a shape easily connecting the plurality of sheet portions 52 such as a rectangular shape. A fixing piece 58 is a part in which a part of the body 55 protrudes outside. Herein, a part of a side edge portion of the body 55 protrudes to a lateral side to be the fixing piece 58. The fixing piece 58 extends to a lateral side of the connection portion. The fixing piece 58 may extend to a lateral side of the edge portions 51a and 51b. The fixing piece 58 may extend from an intermediate portion of the side edge portion of the body 55 to a lateral side.

Any joint state is applicable as a joint state of the sheet portion 52 and the attachment surface 33. For example, the sheet portion 52 and the attachment surface 33 may be joined via a joint member such as an adhesive agent or a double-sided adhesive tape, for example. For example, the sheet portion 52 and the attachment surface 33 may be directly joined without an intervention of the other joint member. For example, the sheet portion 52 and the attachment surface 33 may be directly joined by fusion. When the sheet portion 52 and the attachment surface 33 are fused to each other, at least one of a resin material of the sheet portion 52 and a resin material of the attachment surface 33 is melted and adheres to the other side member. Both the resin material of the sheet portion 52 and the resin material of the attachment surface 33 may be melted and adhere to the other side member. When the resin material of the sheet portion 52 and the resin material of the attachment surface 33 is the same material, both materials are melted and easily adhere to the other side member.

The wiring member 40 passes through the hole 56 of the sheet portion 52 and is disposed on the attachment surface 33, thus there is an overlapping portion in the wiring module 20 in which the sheet portion 52 and the wiring member 40 are overlapped with each other along a normal line direction of the attachment surface 33. Then, there are a portion where the wiring member 40 is covered and a portion where the sheet portion 52 is covered the overlapping portion.

The portion where the wiring member 40 is covered is a portion where the sheet portion 52 covers the wiring member 40. The portion where the wiring member 40 is covered is a portion where the sheet portion 52 is located on an upper side of the wiring member 40 in relation to the attachment surface 33 in the overlapping portion. In the portion where the wiring member 40 is covered, the wiring member 40 is located closer to a side of the attachment surface 33 in relation to the sheet portion 52. The portion of the sheet portion 52 covering the wiring member 40 is referred to as a crest portion 53.

The portion where the sheet portion 52 is covered is a portion where the wiring member 40 covers the sheet portion 52. The portion where the sheet portion 52 is covered is a portion where the wiring member 40 is located on an upper side of the sheet portion 52 in relation to the attachment surface 33 in the overlapping portion. In the portion where the sheet portion 52 is covered, the sheet portion 52 is located closer to the side of the attachment surface 33 in relation to the wiring member 40. The portion of the sheet portion 52 covered by the wiring member 40 is referred to as a trough portion 54.

When one sheet portion 52 is located, one of two edge portions of the holding member serves as the crest portion 53 and the other one thereof serves as a trough portion 54. When two or more sheet portions 52 are connected to each other, one or more connection portions between the sheet portions 52 are provided. One of the two edge portions of the holding member is one of the crest portion 53 and the trough portion 54, and the crest portion 53 and the trough portion 54 are alternately formed continuously to the other edge portion via the connection portion. For example, when two sheet portions 52 are connected to each other, one connection portion is provided. One connection portion is one of the crest portion 53 and the trough portion 54, and each of two edge portions of the holding member 50 serves as the other one of the crest portion 53 and the trough portion 54. When three sheet portions 52 are connected to each other, two connection portions between the sheet portions 52 are provided. One of the two connection portions serves as the crest portion 53 and the other one thereof serves as the trough portion 54. The edge portion in the two edge portions of the holding member 50 connected to the connection portion serving as the trough portion 54 serves as the crest portion 53, and the edge portion connected to the connection portion serving as the crest portion 53 serves as the trough portion 54.

The holding member 50 is attached in an attachment posture in which the sheet portion 52 obliquely extends with respect to the attachment surface 33. In the attachment posture, the electrical wires 41, 42, and 43 may extend as straight as possible as illustrated in FIG. 3. When the attachment posture of the holding member 50 is close to parallel to the attachment surface 33, there may be a case where the electrical wires 41, 42, and 43 meander to get close to and away from the attachment surface 33. For example, when the sheet portion 52 is a hard member, the electrical wires 41, 42, and 43 have contact with a periphery of the hole 56 and meander. At this time, the electrical wire 41, 42, and 43 get closest to the attachment surface 33 in a lower side of the crest portion 53. The electrical wires 41, 42, and 43 get away from the attachment surface 33 from a portion on the lower side of the crest portion 53 toward an upper side of the trough portion 54. In a case where the sheet portion 52 is a soft member, when the attachment posture of the holding member 50 is close to parallel to the attachment surface 33, there may be a case where the sheet portion 52 is bended.

The holding member 50A provided on the branch wire part is described in more detail hereinafter with reference to FIG. 2 to FIG. 5. The holding member 50A in the region A1 is the holding member 50A attached to the first electrical wire 41, and the holding member 50A attached to the second electrical wire 42 and the third electrical wire 43 in the branch wire part also has a similar configuration.

A plurality of holes 56A are formed in the holding member 50A. A plurality of electrical wires 41X, 41Y, and 41Z of the first electrical wire 41 pass through the plurality of holes 56A, respectively. The plurality of holes 56A are disposed to be arranged side by side along one line. The hole 56A is provided only in one stage. The plurality of holes 56A are formed to have the same size. The plurality of holes 56A may be formed to have different sizes. The plurality of holes 56A may have a first hole and a second hole larger than the first hole.

The hole 56A preferably has a shape close to a circular shape when viewed from the extension direction of the electrical wire 41 while the holding member 50A is in the attachment posture. As illustrated in FIG. 4, the hole 56A is formed to have a long size in one side in the sheet portion 52 when viewed from the normal line direction of the sheet portion 52. The hole 56A is formed to have a long size in a direction perpendicular to a direction in which the plurality of holes 56A are arranged side by side. Accordingly, the hole 56A has a shape close to a circular shape when viewed from the extension direction of the electrical wire 41 in the attachment posture.

In the example illustrated in FIG. 2, three electrical wires 41X, 41Y, and 41Z are connected to the wiring side connector C1. Three holes 56AX, 56AY, and 56AZ are formed in the holding member 50A. The three electrical wires 41X, 41Y, and 41Z pass through different holes 56A, respectively. Particularly, the electrical wire 41X passes through the hole 56AX. The electrical wire 41Y passes through the hole 56AY. The electrical wire 41Z passes through the hole 56AZ. An arrangement order of the electrical wires 41X, 41Y, and 41Z in the wiring side connector C1 coincides with an arrangement order of the electrical wires 41X, 41Y, and 41Z in the holding member 50A.

A slit reaching an outer edge of the sheet portion 52 is not formed in a periphery of the hole 56A in the holding member 50A. Thus, the electrical wire 41 is passed through the hole 56A from one surface side of the sheet portion 52 to attach the holding member 50A to the electrical wire herein.

The holding member 50A is provided on the end portion of the wiring member 40. The edge portion 51a on a side of one end portion of the wiring member 40 in the holding member 50A is located closer to the side of the attachment surface 33 in relation to the wiring member 40. The edge portion 51a on the side of one end portion of the wiring member 40 in the holding member 50A is the trough portion 54.

The holding member 50A is attached to the wiring member 40 as follows, for example. That is to say, as illustrated in FIG. 4, the holding member 50A in a folded state is disposed on a near side of a connector housing CH. The holding member 50A is disposed so that a cavity CA in the connector housing CH and the hole 56A corresponding to the electrical wire 41 inserted into the cavity CA are communicated with each other. In this state, the electrical wire 41 is passed through the hole 56A and further inserted into the cavity CA. Accordingly, the holding member 50A is attached to the electrical wire. At this time, the electrical wire 41 is inserted into the cavities CA and the holes 56A arranged in a row sequentially from one side, thus the arrangement order of the electrical wires 41X, 41Y, and 41Z in the wiring side connector C1 coincides with an arrangement order of the electrical wires 41X, 41Y, and 41Z in the holding member 50A. When intervals of the cavities CA and intervals of the holes 56A are different from each other, it is preferable that the connector housing CH and the holding member 50A are relatively moved in a direction in which the holes 56A are arranged side by side so that after the electrical wire 41 is inserted into one group of the corresponding hole 56A and cavity CA, one group of the hole 56A and the cavity CA corresponding to the electrical wire 41 inserted next are communicated with each other. The holding member 50A can be attached to the other electrical wires 42 and 43 in the similar manner.

When the insertion of the electrical wire into the hole 56A and the cavity CA is completed, the holding member 50A is moved to a predetermined position with respect to the wiring member 40 before being joined to the attachment surface 33. The holding member 50A is developed from a folded state before being joined to the attachment surface 33, and takes a predetermined posture with respect to the wiring member 40. At this time, the holding member 50A can be easily moved when it is in the folded state.

The holding member 50 attached to the wiring member 40 is joined to the attachment surface 33 as described hereinafter. That is to say, the wiring member 40 to which the holding member 50 is attached is disposed along a predetermined route on the attachment surface 33. The holding member 50 is moved to a predetermined portion along the extension direction of the electrical wires 41, 42, and 43, and is developed from the folded state. For example, the holding member 50A is moved in a direction away from the connector housing CH from a state of being located on the near side of the connector housing CH. The electrical wires 41, 42, and 43 may be inserted into the hole 56B through the slit 57 while the holding member 50B is located in a predetermined position. The edge portions 51a and 51b on both sides of the holding member 50 are pulled to an opposite direction (outer direction), thus the holding member 50 is developed. Then, the sheet portion 52 (the fixing piece 58 herein) is joined to the attachment surface 33 while the wiring member 40 is disposed along a predetermined route on the attachment surface 33 and the holding member 50 is located in a predetermined position in a predetermined posture on the wiring member 40. All of the holding members 50 are joined to the attachment surface 33 to constitute the wiring module 20.
