[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described.

[0010] The wiring module of the present disclosure is as follows.

[0011] (1) A wiring module that is attached to a long fixed object on one side, comprising: a flat wiring member that extends along the long direction of the fixed object; and a protector that attaches the flat wiring member to the fixed object, wherein the protector includes a support portion that supports the flat wiring member, and a fixing portion and an insertion portion that each protrude from the support portion on the side opposite to the side that supports the flat wiring member, and the protruding dimension of the insertion portion is greater than the protruding dimension of the fixing portion.

[0012] According to the wiring module of (1), the insertion section can be made long, which makes it easier to see the insertion section and to position the tip of the insertion section in the hole of the fixing target, thereby improving the workability of installing the wiring module.

[0013] (2) In the wiring module of (1), the support portion may have a first inward surface that extends from a connecting portion connected to a base end of the insertion portion to one side of the fixed object and faces the fixed object, and a second inward surface that extends from the connecting portion to the other side of the fixed object and faces the fixed object, and when a virtual plane formed by a line connecting a tip of the first inward surface to a tip of the second inward surface in the longitudinal direction of the fixed object is defined as a reference plane, the tip of the insertion portion may extend beyond the reference plane. This allows the insertion portion to be longer than the line connecting the tip of the first inward surface to the tip of the second inward surface when viewed in the longitudinal direction of the fixed object.

[0014] (3) In the wiring module of (1), the support portion may have a first inward surface extending from a connecting portion connected to a base end of the insertion portion to one side of the fixed object and facing the fixed object, and a second inward surface extending from the connecting portion to the other side of the fixed object and facing the fixed object, the dimension from the insertion portion to the tip of the first inward surface may be equal to or shorter than the dimension from the insertion portion to the tip of the second inward surface, and when an imaginary plane that passes through the tip of the first inward surface and is perpendicular to the protruding direction of the insertion portion is taken as a reference plane, the tip of the insertion portion may extend beyond the reference plane. This allows the insertion portion to be longer than the first inward surface.

[0015] (4) In the wiring module of (1), when a virtual plane that passes through the central axis of the object to be fixed and is perpendicular to the protruding direction of the insertion portion is defined as a reference plane, the tip of the insertion portion may extend beyond the reference plane. This allows the insertion portion to be longer than the central axis of the object to be fixed.

[0016] (5) In the wiring module of any one of (1) to (4), the fixing portion may have a first fixing portion provided at a base end of the insertion portion and fixed to a first fixing hole of the fixing target into which the insertion portion is inserted. This allows the protector to be fixed to the fixing target at the position of the insertion portion.

[0017] (6) In the wiring module of (5), the fixing portion may have a second fixing portion fixed to a second fixing hole formed in the fixing target, and the second fixing portion may be shorter than the inserting portion. The fixing portion may include a first fixing portion and a second fixing portion, so that the protector can be fixed to the fixing target at multiple locations. In this case, the inserting portion is inserted into the first fixing hole before the first fixing portion and the second fixing portion, so that the first fixing portion and the second fixing portion can be positioned relative to the fixing target before being fixed.

[0018] (7) In the wiring module of (6), the protector may include a leaf spring that is pressed against the fixed object, and the first fixing portion, the second fixing portion, and the leaf spring may be provided spaced apart from each other along the longitudinal direction of the fixed object. Fixing at multiple locations using the first fixing portion and the second fixing portion and the leaf spring make it easy to suppress rattle of the protector relative to the fixed object.

[0019] (8) In the wiring module of any one of (1) to (7), the flat wiring member includes a base member and a plurality of linear transmission members fixed to the base member, a section of the flat wiring member where the plurality of linear transmission members overlap the base member is defined as a first section, a section where the plurality of linear transmission members extend outside the base member is defined as a second section, the plurality of linear transmission members extend in the second section in a plurality of groups for different connection destinations, the protector includes a partition protrusion provided on the support part and separating the plurality of groups, the partition protrusion and the insertion part may protrude from the same position on the support part to opposite sides. This makes it easier to determine the position of the insertion part based on the position of the partition protrusion when viewing the protector from the side where the partition protrusion is provided.

[0020] In the wiring module of (9) and (8), the fixing portion may be provided at the base end of the insertion portion, and the partition protrusion may have a release hole formed therein for releasing the fixing portion from the hole. By providing the fixing portion at the base end of the insertion portion, the protector can be fixed to the fixing target at the position of the insertion portion. Furthermore, by inserting the insertion portion into the hole before the fixing portion, the fixing portion can be easily positioned to the fixing target before fixing. Furthermore, by forming a release hole in the partition protrusion, the position of the release hole can be easily determined based on the position of the partition protrusion. Furthermore, by separating multiple groups by the partition protrusion, the groups are prevented from covering the release hole.

[0021] [Details of the embodiments of the present disclosure] Specific examples of the wiring module of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0022] [Embodiment 1] The wiring module according to the first embodiment will be described below. Fig. 1 is a perspective view showing the wiring module 10 according to the first embodiment. Fig. 2 is a plan view showing the wiring module 10 of Fig. 1. Fig. 3 is a front view showing the wiring module 10 of Fig. 1. Fig. 4 is a side view showing the wiring module 10 of Fig. 1. Fig. 5 is a perspective view showing a state in which the fixed object 90 and the linear member 30 have been removed from the state of Fig. 1. Fig. 6 is a perspective view showing a state in which the cover 70 has been removed from the state of Fig. 5. Fig. 7 is a perspective view showing a state in which the flat wiring member 20 has been removed from the state of Fig. 6. Fig. 8 is a cross-sectional view taken along line VIII-VIII in Fig. 7. Fig. 8 is a cross-sectional view showing a first section S1 of the flat wiring member 20. The X, Y, and Z directions, which are orthogonal to each other, are shown in each drawing.

[0023] The wiring module 10 includes a flat wiring member 20, a linear member 30, and a protector 40. The wiring module 10 is fixed to a fixed object 90. The flat wiring member 20 and the linear member 30 are fixed to the protector 40. The protector 40 is fixed to the fixed object 90. The flat wiring member 20 and the linear member 30 are fixed to the fixed object 90 via the protector 40.

[0024] <Fixed target> The fixed object 90 is, for example, a rod-shaped member that is long in one direction. Such a fixed object 90 may be a reinforcement that constitutes a part of the vehicle body. The reinforcement may be an instrument panel reinforcement that is placed inside the instrument panel of the vehicle. The instrument panel reinforcement extends along the width direction of the vehicle and connects the left wall and the right wall of the vehicle body. In the example shown in FIG. 1, the longitudinal direction of the fixed object 90 is the X direction. In the vehicle, the X direction is the direction along the vehicle width direction (left-right direction), the Y direction is the direction along the front-rear direction, and the Z direction is the direction along the up-down direction (vertical direction).

[0025] Here, the outer shape of the cross section of the fixed object 90 is circular. Here, the inside of the fixed object 90 is hollow. Therefore, the fixed object 90 is a cylindrical member. The outer shape of the cross section of the fixed object 90 may be a shape other than circular, such as rectangular. The fixed object 90 may also be configured so that there is no hollow inside.

[0026] As shown in Fig. 5, fixing holes 91 and 92 for fixing the protector 40 are formed in the fixing object 90. The fixing holes 91 and 92 are formed, for example, in the upper outer surface of the fixing object 90. The fixing holes 91 and 92 penetrate the outer and inner surfaces of the fixing object 90. In this example, a first fixing hole 91 and a second fixing hole 92 are formed as the fixing holes 91 and 92. The first fixing hole 91 and the second fixing hole 92 are spaced apart from each other along the longitudinal direction of the fixing object 90.

[0027] <Flat wiring material> The flat wiring member 20 includes a base member 21, a plurality of linear transmission members 23, and a plurality of connectors 27. The plurality of linear transmission members 23 are fixed to the base member 21. The plurality of connectors 27 are provided at the ends of the plurality of linear transmission members 23.

[0028] The base member 21 is not particularly limited in material, structure, etc., as long as it can fix the linear transmission member 23. Regarding the material constituting the base member 21, here, the base member 21 is formed of a resin material. The material constituting the base member 21 may be a material other than resin, such as a metal or an inorganic substance.

[0029] The base member 21 may have a single-layer structure or a multi-layer structure of two or more layers. For example, the base member 21 includes a fusion layer. The linear transmission member 23 is fused and fixed to the fusion layer. The fusion layer includes a resin material, preferably a thermoplastic resin material. The resin material of the fusion layer softens and is fused to the fusion partner. The type of such resin material is not particularly limited, and polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), etc. can be used.

[0030] The structure of the bonding layer is not particularly limited. For example, the bonding layer may be a sheet having a uniform solid cross section (also called a non-foamed sheet or a solid sheet). For example, the bonding layer may be a foamed sheet. For example, the bonding layer may be a fibrous sheet such as a knitted fabric, a woven fabric, or a non-woven fabric.

[0031] The base member 21 may include a fusion layer and an additional layer. The additional layer may be formed of a different material or have a different structure from the fusion layer. The additional layer enhances the functionality of the fusion layer or adds functionality not present in the fusion layer to the base member 21. The material constituting the additional layer may be a metal, an inorganic substance, or the like in addition to the materials described for the fusion layer above. The structure of the additional layer may be any of the structures described for the fusion layer above.

[0032] The fusion layer and the additional layer are fixed with their surfaces in contact with each other. The manner in which the fusion layer and the additional layer are fixed is not particularly limited, but they may be fixed by fusion or adhesion. For example, if at least one of the fusion layer and the additional layer is a sheet with voids on its surface, such as a fiber sheet or a foam sheet, a resin material or adhesive can fill the voids and fix them. This produces a so-called anchor effect, firmly fixing the fusion layer and the additional layer.

[0033] For example, the fusion layer may be a solid resin sheet, the additional layer may be a fibrous sheet, and the fusion layer and the additional layer may be fused together. The resin of the fusion layer may be infiltrated between the fibers of the additional layer in a fluid state and then hardened. This maintains the state in which the resin of the fusion layer is infiltrated between the fibers of the additional layer, and the fusion layer and the additional layer are firmly fixed together.

[0034] The adhesive layer and the additional layer may be formed to have the same size (same planar shape). One of the adhesive layer and the additional layer may be formed larger than the other. The adhesive layer and the additional layer may be fixed over the entire contact area, or only a part of the contact area may be fixed.

[0035] The base member 21 may be a soft member. For example, the fusion layer may be a solid sheet made of a soft resin such as soft PVC, and the additional layer may be a nonwoven fabric made of PET, so that the base member 21 is a soft member. For example, the base member 21 may have flexibility that allows it to follow the bending of the linear transmission member 23. The flat wiring member 20 may be bendable in the thickness direction (bending such that the folds follow the holding surface of the base member 21).

[0036] The linear transmission member 23 is a linear member that transmits electricity, light, or the like. The linear transmission member 23 is expected to be a member that connects components in a vehicle. As shown in FIG. 8 , the linear transmission member 23 includes a transmission line main body 24 and a coating layer 25. The transmission line main body 24 is a transmission path that transmits electricity or light. For example, if the linear transmission member 23 is an electric wire, the transmission line main body 24 is a conductor core wire. The conductor core wire is composed of one or more element wires. The element wires are formed from copper, copper alloy, aluminum, aluminum alloy, or the like. Furthermore, if the linear transmission member 23 is an optical fiber, the transmission line main body 24 is composed of a core and clad. The coating layer 25 is a layer that covers the transmission line main body 24. For example, if the linear transmission member 23 is an electric wire, the coating layer 25 is an insulating coating. The coating layer 25 is composed of, for example, a resin material. The resin material that constitutes the coating layer 25 is not particularly limited and can be set as appropriate.

[0037] The linear transmission member 23 may be, for example, a general electric wire having a core wire and a coating layer surrounding the core wire, or may be a shielded wire, a twisted wire, an enameled wire, a nichrome wire, an optical fiber, etc. The linear transmission member 23 that transmits electricity may be any of various signal lines and power lines. A part of the linear transmission member 23 that transmits electricity may be used as an antenna, a coil, etc. that sends or receives signals or power to or from space.

[0038] Furthermore, the linear transmission member 23 may be a single-core wire. A single-core wire is a single linear object. A single-core wire is a linear transmission member with one transmission path. The linear transmission member 23 may be a multi-core wire. A multi-core wire is a composite of multiple linear objects. A multi-core wire is a linear transmission member with multiple transmission paths. A multi-core wire may be, for example, a twisted wire, a cable in which multiple linear objects are assembled and covered with a sheath, or the like.

[0039] The fixing mode of the base member 21 and the linear transmission member 23 may be contact-part fixing, non-contact-part fixing, or a combination of both. Here, contact-part fixing means that the base member 21 and the linear transmission member 23 are fixed by adhering to each other at their contacting portions. Non-contact-part fixing means a fixing mode other than contact-part fixing, such as using sewing thread, a cover, adhesive tape, or the like to press the linear transmission member 23 toward the base member 21 or to sandwich the base member 21 and the linear transmission member 23 together, thereby maintaining that state.

[0040] The manner of fixing the contact portions may be indirect fixing of the contact portions, direct fixing of the contact portions, or a combination of both in different regions. Here, indirect fixing of the contact portions refers to the base member 21 and the linear transmission member 23 being indirectly fixed to each other via an adhesive, pressure-sensitive adhesive, double-sided adhesive tape, or the like provided between them. Direct fixing of the contact portions refers to the base member 21 and the linear transmission member 23 being directly fixed to each other without the use of a separate adhesive or the like. In direct fixing of the contact portions, for example, the base member 21 and the linear transmission member 23 may be fixed to each other by melting a resin contained in at least one of them.

[0041] When such a state of direct fixation of the contact regions is formed, the resin may be melted by, for example, heat or a solvent. That is, the state of direct fixation of the contact regions may be a state of direct fixation of the contact regions by heat or a state of direct fixation of the contact regions by a solvent. Preferably, the state of direct fixation of the contact regions is a state of direct fixation of the contact regions by heat.

[0042] The means for achieving this direct contact fixation is not particularly limited, and known means such as fusion can be used. For example, when achieving this direct contact fixation by heat fusion, various fusion means can be used, such as ultrasonic fusion, heat and pressure fusion, hot air fusion, and high-frequency fusion. When this direct contact fixation is achieved by these means, the base member 21 and the linear transmission member 23 are directly fixed to each other by that means. Specifically, when this direct contact fixation is achieved by ultrasonic fusion, the base member 21 and the linear transmission member 23 are directly fixed to each other by ultrasonic fusion. Therefore, the fusion fixation is one form of direct contact fixation. Figure 8 shows the fusion portion FX1 between the base member 21 and the linear transmission member 23.

[0043] Here, the base member 21 and the linear transmission member 23 are directly fixed at the contact area. In this case, the outermost layer of the linear transmission member 23 is fused to the fusion layer. The outermost layer of the linear transmission member 23 is the coating layer 25. The coating layer 25 is made of a material that can be fused to the fusion layer. The resin material constituting the coating layer 25 may be the same type as the resin material constituting the fusion layer. For example, the resin material constituting the fusion layer and the resin material constituting the coating layer 25 are PVC or polyolefin.

[0044] The plurality of linear transmission members 23 overlap with the base member 21 in some sections and do not overlap with the base member 21 in other sections. A section of the flat wiring member 20 where the plurality of linear transmission members 23 overlap with the base member 21 is referred to as a first section S1. A section of the flat wiring member 20 where the plurality of linear transmission members 23 extend outside the base member 21 is referred to as a second section S2. The first section S1 extends along the longitudinal direction (X direction) of the fixed object 90. As shown in FIG. 7 and other figures, here, the second section S2 is provided at an end portion along the longitudinal direction of the first section S1. The linear transmission members 23 may branch off from an intermediate portion along the longitudinal direction of the base member 21, thereby providing the second section S2 in an intermediate portion along the longitudinal direction of the first section S1.

[0045] As shown in FIG. 8, in the first section S1, the flat wiring member 20 may have a layered structure in which a plurality of wiring bodies 26 are stacked. Each of the plurality of wiring bodies 26 includes a base member 21 and a linear transmission member 23. The base members 21 of the plurality of wiring bodies 26 may be joined together at a joint and maintained in a layered state. The joint may be formed by fusing the base members 21 together, or by joining using a fixing part separate from the base members 21. FIG. 8 shows a fused portion FX2 between the base members 21. The fused portion FX2 is provided to the side of the fused portion FX1.

[0046] In the example shown in FIG. 8, the linear transmission members 23 of the two outermost wiring bodies 26 are located inside the base member 21. As a result, in the flat wiring member 20, the linear transmission members 23 of each layer are arranged between the two outermost base members 21. The linear transmission member 23 of at least one of the two outermost wiring bodies 26 may be located outside the base member 21. In the example shown in FIG. 8, two wiring bodies 26 are stacked. Three or more wiring bodies 26 may be stacked.

[0047] As shown in FIG. 7, the base member 21 has a fixing piece 22 that is fixed to the protector 40. The fixing piece 22 protrudes laterally from a side edge of the arrangement main body portion of the base member 21 where the linear transmission member 23 is arranged. A slit 22S is formed in the fixing piece 22. The fixing piece 22 is provided on at least one base member 21 of the multiple wiring bodies 26. The fixing piece 22 may be provided at a joint between the base members 21, or may be provided separately from the joint.

[0048] The multiple linear transmission members 23 extend in the second section S2 in multiple groups corresponding to different connection destinations. Here, the multiple groups include a first group G1, a second group G2, and a third group G3. The first group G1 and the second group G2 extend toward the same side. The third group G3 extends toward the opposite side from the first group G1 and the second group G2. The first group G1 and the second group G2 extend toward one side of the fixed object 90, and the third group G3 extends toward the other side of the fixed object 90. At the base end of the second section S2, the first group G1 is located between the second group G2 and the third group G3. The multiple linear transmission members 23 may or may not be bundled in each group G1, G2, and G3 using adhesive tape or the like. Each figure shows the multiple linear transmission members 23 bundled in each group G1, G2, and G3.

[0049] The first group G1, the second group G2, and the third group G3 extend from the first section S1 along the longitudinal direction of the fixed object 90. The first group G1 and the second group G2 extend from the first section S1, then bend, and extend toward one side of the fixed object 90. The third group G3 extends from the first section S1, then bend, and extend toward the other side of the fixed object 90. The first group G1 bends on a side farther from the first section S1 than the second group G2 along the longitudinal direction of the fixed object 90.

[0050] The division of the plurality of linear transmission members 23 into the first group G1, the second group G2, and the third group G3 is not particularly limited and can be set as appropriate. When the first section S1 of the flat wiring member 20 has a stacked structure of a plurality of wiring bodies 26, for example, a single layer may contain a mixture of linear transmission members 23 from a plurality of groups. Alternatively, for example, the linear transmission members 23 may be divided into groups by layer. In other words, a configuration may be adopted in which one group of linear transmission members 23 is provided in only one layer.

[0051] The multiple connectors 27 include a first connector 27A, a second connector 27B, and a third connector 27C. The first connector 27A is provided at an end of the first group G1. The second connector 27B is provided at an end of the second group G2. The third connector 27C is provided at an end of the third group G3. The connectors 27 are connected to mating connectors.

[0052] 1, each connector 27 has a connector housing CH, a lever RV, and a connector terminal (not shown). The connector terminal is connected to an end of the linear transmission member 23. When the connector 27 is connected to a mating connector, the connector terminal is connected to a mating connector terminal of the mating connector. When the linear transmission member 23 is an electric wire, the connector terminal is a conductor, and the connector housing CH is an insulator.

[0053] The connector housing CH holds a plurality of connector terminals in a predetermined arrangement. As shown in Fig. 1, a plurality of cavities CV are formed in the connector housing CH. The cavities CV are, for example, through holes that penetrate the front and rear surfaces of the connector housing CH. Note that the cavities CV are omitted from figures other than Fig. 1. The linear transmission member 23 and the connector terminals are held in predetermined cavities CV of the connector housing CH. The linear transmission member 23 extends from the opening of the cavity CV in the rear surface of the connector housing CH.

[0054] The lever RV is rotatably supported on the side surface of the connector housing CH. For example, the lever RV has a pair of support pieces rotatably supported on a pair of side surfaces of the connector housing CH, and a connecting piece connecting the pair of support pieces. The rotation axis of the lever RV is in a direction connecting the pair of side surfaces of the connector housing CH. The connector 27 is supported so that the rotation axis of the lever RV is along the X direction. The lever RV rotates when the connector 27 is mated with the mating connector. The lever RV is used to transition the connector 27 and the mating connector to a mated state, maintain the mated state, etc.

[0055] <Linear members> The linear member 30 is provided separately from the flat wiring member 20. The linear member 30 may be a member that transmits electricity or light, similar to the linear transmission member 23 in the flat wiring member 20. The linear member 30 may be a hose for transmitting a fluid. There may be one linear member 30 or multiple linear members 30. The end of the linear member 30 may be connected to the same connection destination as the flat wiring member 20, or may be connected to a connection destination different from that of the flat wiring member 20.

[0056] Here, an intermediate portion along the extension direction of the linear member 30 is fixed to the protector 40. The linear member 30 is provided with a fixing member 32. The fixing member 32 is a member for fixing the linear member 30 to the protector 40. Here, the fixing member 32 includes a fixing portion 33 and an attachment plate portion 34.

[0057] The fixing portion 33 is a portion fixed to the protector 40. The protector 40 is provided with wire fixing portions 60, 76 to which the fixing portion 33 is fixed. Here, a clamp is provided as the fixing portion 33. The wire fixing portions 60, 76 are formed with locking holes into which the clamp is locked. The clamp has a post portion and a locking piece protruding from the post portion. When the clamp is inserted into the locking hole, the locking piece contacts the periphery of the locking hole, allowing elastic deformation so that the width of the locking piece decreases. This allows the clamp to pass through the locking hole. After the clamp passes through the locking hole, the locking piece elastically returns to its original position and locks onto the periphery of the locking hole. This fixes the fixing member 32 to the protector 40.

[0058] The mounting plate portion 34 is a portion for mounting the fixing member 32 to the linear member 30. Here, the mounting plate portion 34 is formed in a plate shape extending along the linear member 30. As shown in Fig. 5, the fixing member 32 is mounted to the linear member 30, for example, by wrapping a binding member such as adhesive tape 36 around the mounting plate portion 34 and the linear member 30.

[0059] Here, the linear member 30 is a bendable member and is held in a bent state by the mounting plate portion 34. Specifically, the mounting plate portion 34 is formed in an L-shaped plate shape. The mounting plate portion 34 has a first plate portion and a second plate portion that intersect with each other. Each of the first plate portion and the second plate portion is bound to the linear member 30. As a result, the portion of the linear member 30 where the fixing member 32 is provided is path-regulated so that it extends in an L-shape. A fixing portion 33 is provided at the connecting portion of the first plate portion and the second plate portion. Note that the mounting plate portion 34 may be formed in a straight line to path-regulate the linear member 30 in a straight line.

[0060] Here, fixing members 32 are provided at two locations spaced apart along the extension direction of the linear member 30. The path of the linear member 30 is restricted at the positions of the two fixing members 32 so that it extends in an L-shape.

[0061] <Protector> The protector 40 will be described with reference to Figures 9 to 13 in addition to Figures 1 to 8. Figure 9 is a front view showing the protector main body 41 and the cover 70. Figure 10 is a rear view showing the protector main body 41 and the cover 70. Figure 11 is a plan view showing the protector main body 41. Figure 12 is a side view showing the protector main body 41. Figure 13 is a cross-sectional view of the protector 40 taken along line XIII-XIII in Figure 11.

[0062] The protector 40 is provided at the end of the flat wiring member 20. The end of the first section S1 and the second section S2 are supported by the protector 40. The middle part of the first section S1 is not supported by the protector 40. Therefore, the first section S1 has a section that is supported by the protector 40 and a section that is not supported.

[0063] The protector 40 includes a first holding portion for holding the flat wiring member 20, an attachment portion for being attached to a fixed object 90, and a second holding portion for holding the linear member 30. Here, the protector 40 includes a protector main body 41 and a cover 70 provided separately from the protector main body 41. The protector main body 41 and the cover 70 are molded separately from each other. The cover 70 has a locking portion 71, and the protector main body 41 has a receiving portion 65. The protector main body 41 and the cover 70 are combined together by fitting the locking portion 71 into the receiving portion 65. The first holding portion, the attachment portion, and the second holding portion are each provided on the protector main body 41 or the cover 70.

[0064] <1st holding part> The protector 40 includes a support portion 42, a partition protrusion 47, and a guide protrusion 48 as a first holding portion for holding the flat wiring member 20.

[0065] The support portion 42 supports the flat wiring member 20. As shown in FIG. 13 , the support portion 42 includes a support body 43 and a pair of extension portions 44. The support body 43 covers the fixed object 90. The support body 43 is formed to have a shape corresponding to the outer shape of the fixed object 90. Here, the support body 43 is formed in a cylindrical shape with a portion of the circumferential direction open to accommodate the fixed object 90, which has a circular outer shape. The support body 43 is formed in a semi-cylindrical shape, obtained by splitting a cylinder in half along the axial direction. One of the pair of extension portions 44 extends from one end of the support body 43, and the other extends from the other end of the support body 43. Here, one extension portion 44 extends from one end of the support body 43 in the radial direction of the fixed object 90. The other extension portion 44 extends from the other end of the support body 43 in the tangential direction of the fixed object 90. The extension portions 44 may extend in a direction different from the radial direction and tangential direction of the fixed object 90.

[0066] The support portion 42 has a first support portion 42A and a second support portion 42B. The first support portion 42A supports the first section S1. The second support portion 42B is connected to the first support portion 42A and supports the second section S2. Here, one end of the support portion 42 along the longitudinal direction of the fixed object 90 is the first support portion 42A, and the other end is the second support portion 42B.

[0067] An end of the first section S1 is supported on the support portion 42. In the first section S1, the base member 21 is held by the protector 40. The protector 40 includes a base holding portion 45 that is provided on the first support portion 42A and holds the base member 21. Here, a base holding portion 45 is provided on each of the pair of extension portions 44. As shown in FIG. 11 , the base holding portion 45 has a clamping plate portion 45a, a hinge portion 45b, a locking protrusion 45c, and a locking hole 45d. The clamping plate portion 45a is connected to the extension portion 44 via the hinge portion 45b. The clamping plate portion 45a is rotatably connected to the extension portion 44 by the hinge portion 45b. The locking protrusion 45c protrudes from the main surface of the extension portion 44. The locking hole 45d is formed in the clamping plate portion 45a. A through hole through which the locking protrusion 45c passes is formed in the base member 21. With the base member 21 sandwiched between the clamping plate portion 45a and the extending portion 44, the locking protrusion 45c passes through the through-hole and locks into the locking hole 45d. This maintains the base member 21 sandwiched between the clamping plate portion 45a and the extending portion 44.

[0068] In the second section S2, each of the groups G1, G2, and G3 extends on the support portion 42. In the second section S2, the connector 27 is held by the protector 40. The protector 40 includes a connector holding portion 46 that is provided on the second support portion 42B and holds the connector 27. The connector holding portion 46 is provided on the extension portion 44 of the protector body 41. As shown in FIG. 11 and other figures, the connector holding portion 46 is formed in a slot shape. A cassette portion CS is provided on the underside of the connector housing CH. The connector holding portion 46 is inserted into and engages with the cassette portion CS of the connector 27. The cassette portion CS of the connector 27 is inserted into the connector holding portion 46 along the axial direction of the cavity CV.

[0069] The protector 40 includes a first connector holding portion 46A that holds the first connector 27A, a second connector holding portion 46B that holds the second connector 27B, and a third connector holding portion 46C that holds the third connector 27C. The first connector holding portion 46A and the second connector holding portion 46B are provided on one of a pair of extension portions 44, and the third connector holding portion 46C is provided on the other extension portion 44. Each group G1, G2, and G3 extends from an edge of the base member 21 toward the corresponding connector holding portion 46. The first connector holding portion 46A and the second connector holding portion 46B are aligned along the longitudinal direction of the fixed target 90. The first connector holding portion 46A and the second connector holding portion 46B hold the first connector 27A and the second connector 27B so that the axial direction of the cavity CV is horizontal. The third connector holding portion 46C holds the third connector 27C so that the axial direction of the cavity CV is vertical.

[0070] The connector 27 moves along the axial direction of the cavity CV, and the cassette portion CS is inserted into the connector holding portion 46. In the first connector holding portion 46A and the second connector holding portion 46B, the first connector 27A and the second connector 27B move in the Y direction, and the cassette portion CS is inserted into the connector holding portion 46. In the third connector holding portion 46C, the third connector 27C moves in the Z direction, and the cassette portion CS is inserted into the connector holding portion 46. The connector housing CH approaches the connector holding portion 46 from the rear end from which the linear transmission member 23 extends.

[0071] The partitioning protrusion 47 is provided on the second support portion 42B. The partitioning protrusion 47 separates the multiple groups from one another. As shown in FIG. 11, the partitioning protrusion 47 separates the first group G1 and the second group G2. The bent portion of the first group G1 is located farther from the first section S1 than the partitioning protrusion 47. The bent portion of the second group G2 is located closer to the first section S1 than the partitioning protrusion 47. The first group G1 extends from the base member 21 and continues to extend in the X direction, then passes the partitioning protrusion 47 and bends to one side. The second group G2 extends from the base member 21 and bends to one side before the partitioning protrusion 47.

[0072] The partition protrusion 47 protrudes upward from the support body 43 of the support part 42. The protruding dimension of the partition protrusion 47 is not particularly limited, but may be, for example, the same as or larger than the diameter of the first group G1 when bundled into a circular shape.

[0073] The guide protrusion 48 is located between the first connector holding portion 46A and the second connector holding portion 46B. As shown in Fig. 12, the guide protrusion 48 is provided between the side surfaces of the connector housing CH to prevent the levers RV from coming into contact with each other. The guide protrusion 48 is located to the side of the lower part of the side surface of the connector housing CH. The mounting piece of the lever RV is located above the guide protrusion 48.

[0074] In the parallel direction of the first connector 27A and the second connector 27B, the dimension of the guide protrusion 48 is greater than twice the protrusion dimension of the lever RV from the side surface of the connector housing CH in one connector 27. Even if the side surfaces of the two connector housings CH come into contact with the guide protrusion 48, the levers RV are configured not to come into contact with each other.

[0075] The guide protrusions 48 are formed in a tapered shape that gradually narrows toward the front in the insertion direction of the cassette part CS. As a result, when the cassette part CS of the connector 27 is inserted into the connector holding part 46, the rear part of the connector housing CH is guided by the tip of the guide protrusions 48. The guide protrusions 48 are formed in the shape of two ribs that are spaced apart in the X direction. The distance between the two ribs gradually decreases toward the front in the insertion direction, and the two ribs connect to each other at the frontmost side.

[0076] The guide protrusion 48 and the partition protrusion 47 are connected. A connecting protrusion 49 extends from the partition protrusion 47 toward one side of the fixed object 90, and the guide protrusion 48 is provided at the end of the connecting protrusion 49. The connecting protrusion 49 and the partition protrusion 47 are also formed in the shape of two ribs, similar to the guide protrusion 48. In the partition protrusion 47, the two ribs extend in the X direction and are connected to each other. However, the connecting protrusion 49 may not be provided, and the guide protrusion 48 and the partition protrusion 47 may be configured not to be connected.

[0077] The third connector holding portion 46C supports the third connector 27C so that the opening of the cavity CV faces upward. The cover 70 covers the opening of the cavity CV of the third connector 27C from above. This prevents water from entering the cavity CV of the third connector 27C. This prevents water from splashing on the connector terminals of the third connector 27C.

[0078] To further prevent water from entering the cavity CV of the third connector 27C, the cover 70 has a portion that covers the first section S1 of the flat wiring member 20. The cover 70 covers the first section S1 between the base holding portions 45 on both sides. The base ends of the third group G3 that extend from the first section S1 are covered by the cover 70. The cover 70 covers almost the entire third group G3 from above. This prevents water from splashing on the third group G3 at a position away from the cavity CV. This prevents water that splashes on the third group G3 at a position away from the cavity CV from seeping into the cavity CV along the linear transmission member 23 of the third group G3.

[0079] To further facilitate preventing water from entering cavity CV of third connector 27C, cover 70 is provided with downward walls 73. The downward walls 73 protrude downward from the edge of cover 70 that extends along the longitudinal direction of object 90. The downward walls 73 overlap with partition walls 62 of protector body 41 along the longitudinal direction of object 90. The downward walls 73 are positioned further outward than partition walls 62 along the longitudinal direction of object 90. The overlapping portion of downward walls 73 and partition walls 62 functions as a labyrinth structure that prevents water from entering from the edge of cover 70.

[0080] Two locking portions 71 are provided on the downward wall 73. As shown in Fig. 9, the two locking portions 71 are provided on both ends of the downward wall 73. When the two locking portions 71 are locked to the receiving portions 65, the overlapping state of the downward wall 73 and the partition wall 62 is easily maintained. The other locking portion 71 is provided between the portion of the cover 70 that covers the first section S1 and the portion that covers the third connector 27C.

[0081] The first connector 27A and the second connector 27B are not covered by the cover 70. Here, the first connector 27A and the second connector 27B are supported so that the openings of the cavities CV face horizontally. Therefore, even if the first connector 27A and the second connector 27B are not covered by the cover 70, water is less likely to enter the cavities CV of the first connector 27A and the second connector 27B and get on the connector terminals. For the same reason, the entire second group G2 and part of the first group G1 are not covered by the cover 70.

[0082] Another part of the first group G1 is covered by the cover 70. The middle part of the first group G1 located around the partitioning protrusion 47 is covered by the cover 70. This is to make it easier to maintain the partitioned state between the first group G1 and the second group G2. Furthermore, to make it easier to maintain the partitioned state between the first group G1 and the second group G2, the cover 70 is provided with a fitting recess 74 (see FIG. 6) and a pressing wall 75 (see FIG. 10).

[0083] The mating recess 74 is formed on the side edge of the cover 70. The upper part of the partition protrusion 47 fits into the mating recess 74. By fitting the partition protrusion 47 into the mating recess 74, the gap between the side edge of the cover 70 and the partition protrusion 47 is reduced. This makes it possible to prevent the linear transmission member 23 of the first group G1 from entering the gap. In addition, by fitting the partition protrusion 47 into the mating recess 74, the cover 70 and the protector main body 41 can be positioned. A locking portion 71 at one end of the downward wall 73 is located on the opposite side of the mating recess 74.

[0084] The pressing wall 75 protrudes downward from the side edge of the cover 70. The pressing wall 75 is located closer to the first section S1 than the fitting recess 74. The pressing wall 75 presses the side of the first group G1 closer to the first section S1 than the partition protrusion 47. This prevents the first group G1 from being positioned closer to the second connector 27B than the pressing wall 75.

[0085] <Mounting part> The protector 40 includes a fixing portion 50, an insertion portion 52, and a leaf spring 53 as mounting portions for mounting to a fixed object 90. The fixing portion 50, the insertion portion 52, and the leaf spring 53 protrude from the surface of the support body 43 opposite to the surface that supports the flat wiring member 20. The fixing portion 50, the insertion portion 52, and the leaf spring 53 protrude from the same side as the support portion 42.

[0086] The fixing portion 50 is a portion that is fixed to a fixing target 90. The fixing portion 50 includes a first fixing portion 50A and a second fixing portion 50B. The first fixing portion 50A and the second fixing portion 50B are spaced apart in the X direction. The first fixing portion 50A is fixed to a first fixing hole 91. The second fixing portion 50B is fixed to a second fixing hole 92. Here, the fixing portion 50 is a clamp that has a pillar portion and a locking piece that protrudes from the pillar portion, similar to the fixing portion 33 of the fixing member 32.

[0087] The first fixing portion 50A is provided on the second support portion 42B. The first fixing portion 50A and the partition protrusion 47 protrude from the same position on the second support portion 42B to opposite sides. The partition protrusion 47 has a release hole RH for releasing the fixed state of the first fixing portion 50A relative to the first fixing hole 91. Here, the base end of the clamp's post and the release hole RH are located within the area surrounded by the ribs of the partition protrusion 47. The release hole RH allows access to the clamp's locking piece, which can be deformed to reduce its width. The tip of the clamp's locking piece may protrude above the top surface of the support body 43.

[0088] A release hole RH is also formed at the position of the second fixed portion 50B. The release hole RH of the second fixed portion 50B is not covered by the flat wiring member 20. This makes it easy to release the second fixed portion 50B through the release hole RH. The linear transmission member 23 of the flat wiring member 20 is configured not to extend toward the second fixed portion 50B. The second fixed portion 50B is located farther from the first section S1 than the first fixed portion 50A. A partition wall 62 is formed in the protector 40 between the portion where the second fixed portion 50B is provided and the partition protrusion 47. The provision of the partition wall 62 prevents the linear transmission member 23 of the first group G1 from extending toward the second fixed portion 50B beyond the partition wall 62. In addition, a receiving portion 65 is provided in a portion of the partition wall 62 located between the first fixed portion 50A and the second fixed portion 50B. The portion of the linear transmission member 23 of the first group G1 that is located between the partition wall 62 and the partition protrusion 47 is covered with a cover 70.

[0089] The insertion portion 52 is a portion that is inserted into the fixed object 90 before the fixing portion 50. The insertion portion 52 is longer than the fixing portion 50. The first fixing portion 50A and the second fixing portion 50B are shorter than the insertion portion 52. The amount by which the insertion portion 52 protrudes from the support body 43 is greater than the amount by which the fixing portion 50 protrudes from the support body 43. By inserting the insertion portion 52 into the fixed object 90, it is possible to position the fixing portion 50 relative to the fixed object 90 before fixing. The tip of the insertion portion 52 is formed in a tapered shape. This makes it easier for the insertion portion 52 to be inserted into the fixed object 90.

[0090] Here, the insertion portion 52 is provided at the position of the first fixing portion 50A. The first fixing portion 50A is provided at the base end of the insertion portion 52. The insertion portion 52 protrudes from the tip of the pillar portion of the first fixing portion 50A. The insertion portion 52 is inserted into the first fixing hole 91 to which the first fixing portion 50A is fixed. In the fixing object 90, one hole (first fixing hole 91) can be used both as a hole for inserting the insertion portion 52 and as a hole for fixing the first fixing portion 50A. This makes it possible to prevent the number of holes in the fixing object 90 from increasing. Furthermore, since the insertion portion 52 is provided at the position of the first fixing portion 50A, the insertion portion 52 is provided on the opposite side from the partition protrusion 47.

[0091] The protruding dimension of the insertion portion 52 can be set as appropriate within a range longer than the fixed portion 50. For example, the dimension from the support portion 42 to the tip of the insertion portion 52 may be at least twice the dimension from the support portion 42 to the tip of the first fixed portion 50A.

[0092] The support portion 42 has a first inward surface 43a and a second inward surface 43b. The portion of the support portion 42 that continues to the base end of the insertion portion 52 is referred to as the connecting portion. Here, the connecting portion is the portion that continues to the base end of the partition protrusion 47. The first inward surface 43a extends from the connecting portion to one side of the fixed object 90 and faces the fixed object 90. The second inward surface 43b extends from the connecting portion to the other side of the fixed object 90 and faces the fixed object 90.

[0093] 13 is an imaginary plane formed by a line connecting the tip of the first inward surface 43a and the tip of the second inward surface 43b, which is continuous in the longitudinal direction of the fixed object 90. As shown in FIG. 13, the length of the insertion portion 52 may be set so that the tip of the insertion portion 52 extends beyond the reference plane VS1.

[0094] However, a reference plane other than the reference plane VS1 may be set as the reference plane.

[0095] For example, the reference plane VS2 shown in FIG. 13 may be set as the reference plane. The reference plane VS2 is an imaginary plane that passes through the tip of the inward surface 43a and is perpendicular to the protruding direction of the insertion portion 52. As shown in FIG. 13, the length of the insertion portion 52 may be set so that the tip of the insertion portion 52 extends beyond the reference plane VS2. The inward surface 43a related to the reference plane VS2 is a surface that is the same as or shorter than the other inward surfaces 43b. In other words, the dimension from the connecting portion to the tip of the inward surface 43a is the same as or shorter than the dimension from the connecting portion to the tip of the other inward surface 43b.

[0096] 3 may be set as the reference plane. The reference plane VS3 is a virtual plane that passes through the central axis of the fixed object 90 and is perpendicular to the protruding direction of the insertion portion 52. As shown in FIG. 3, the length of the insertion portion 52 may be set so that the tip of the insertion portion 52 extends beyond the reference plane VS3.

[0097] The upper limit of the length of the insertion portion 52 is preferably set to a length that positions the tip of the insertion portion 52 inside the cylindrical fixing target 90. In other words, the tip of the insertion portion 52 is preferably configured so that it does not penetrate the outer surface of the fixing target 90 on the side opposite to the first fixing hole 91 and protrude beyond the outer surface of the fixing target 90. For example, if the outer surface of the fixing target 90 is circular, the length of the insertion portion 52 may be equal to or less than the diameter of the outer surface of the fixing target 90. However, the tip of the insertion portion 52 may also penetrate the fixing target 90 on the side opposite to the first fixing hole 91.

[0098] The leaf spring 53 is pressed against the fixed object 90. When the fixing portion 50 is fixed to the fixing holes 91, 92, the leaf spring 53 bends, thereby suppressing rattle of the protector 40. The leaf spring 53 may be omitted. The leaf spring 53 is a cut-out portion of the support body 43 such that a portion of the support body 43 protrudes downward relative to other portions of the support body 43. In the Z direction, the leaf spring 53 is shorter than the fixing portion 50. The leaf spring 53 is provided on the first support portion 42A. The leaf spring 53 is covered by the first section S1. Unlike the fixing portion 50, the leaf spring 53 does not require any operation by an operator to release it. Therefore, even if the leaf spring 53 is covered by the flat wiring member 20, the workability is not impaired when removing the protector 40 from the fixed object 90.

[0099] The first fixing portion 50A, the second fixing portion 50B, and the leaf spring 53 are provided at a distance from each other along the longitudinal direction of the fixed object 90. The order of the first fixing portion 50A, the second fixing portion 50B, and the leaf spring 53 is not particularly limited and can be set as appropriate. Here, the second fixing portion 50B is provided on the opposite side of the first fixing portion 50A from the leaf spring 53 in the X direction. In other words, the first fixing portion 50A is located between the second fixing portion 50B and the leaf spring 53. The second fixing portion 50B may be located between the first fixing portion 50A and the leaf spring 53. The leaf spring 53 may be located between the first fixing portion 50A and the second fixing portion 50B.

[0100] <Second holding part> The protector 40 includes a wire holding portion 54 and wire fixing portions 60, 76 as second holding portions for holding the wire member 30. The wire holding portion 54 holds the wire member 30. The wire fixing portions 60, 76 are portions where the wire member 30 is fixed at a position separate from the wire holding portion 54. The wire fixing portions 60, 76 include a first wire fixing portion 60 and a second wire fixing portion 76.

[0101] The wire holding portion 54 has a first claw portion 55A and a second claw portion 55B aligned along the extension direction (here, the X direction) of the linear member 30 held by the wire holding portion 54. One wire holding portion 54 is provided with only the first claw portion 55A and the second claw portion 55B as claw portions.

[0102] The first claw portion 55A has a first side wall 56A and a first pressing piece 57A. The first side wall 56A covers one side of the linear member 30. The first pressing piece 57A protrudes from the first side wall 56A. The first pressing piece 57A extends toward the other side of the linear member 30.

[0103] The second claw portion 55B has a second side wall 56B and a second pressing piece 57B. The second side wall 56B covers the other side of the linear member 30. The first side wall 56A and the second side wall 56B are spaced apart in the Y direction. The second pressing piece 57B protrudes from the second side wall 56B. The second pressing piece 57B extends toward one side of the linear member 30.

[0104] The first pressure piece 57A and the second pressure piece 57B are spaced apart in the X direction. The distance between the first pressure piece 57A and the second pressure piece 57B can be set as appropriate. For example, the distance between the first pressure piece 57A and the second pressure piece 57B in the X direction may be equal to or smaller than the dimensions of each pressure piece 57A, 57B. In the example shown in FIG. 11, the distance between the first pressure piece 57A and the second pressure piece 57B in the X direction is smaller than the dimensions of each pressure piece 57A, 57B.

[0105] The tip of the first pressing piece 57A and the tip of the second pressing piece 57B face each other in the X direction. As shown in Fig. 9, the tip of the first pressing piece 57A and the tip of the second pressing piece 57B intersect to form an X shape when viewed from the X direction. The tip of the first pressing piece 57A and the tip of the second pressing piece 57B may also form a V shape or a T shape when viewed from the X direction.

[0106] As shown in FIG. 10, the first claw portion 55A has a first opposing wall 58A opposing the first side wall 56A. As shown in FIG. 9, the second claw portion 55B has a second opposing wall 58B opposing the second side wall 56B. In each of the claw portions 55A and 55B, the linear member 30 is inserted through an upper opening between the side wall 56A, 56B and the opposing wall 58A, 58B. In each of the claw portions 55A and 55B, the pressing pieces 57A and 57B narrow the upper opening between the side wall 56A, 56B and the opposing wall 58A, 58B. No pressing pieces or protrusions for pressing the linear member 30 are provided on the inner surface of each of the opposing walls 58A and 58B facing the linear member 30. Reinforcing ribs are provided on the outer surface of each of the opposing walls 58A and 58B opposite the inner surface.

[0107] 4, the first side wall 56A and the second opposing wall 58B are spaced apart in the X direction. That is, a slit is formed between the first side wall 56A and the second opposing wall 58B. Similarly, the second side wall 56B and the first opposing wall 58A are spaced apart in the X direction. A slit is also formed between the second side wall 56B and the first opposing wall 58A. This makes it easier for the first claw portion 55A and the second claw portion 55B to deform when the linear member 30 is inserted.

[0108] As shown in FIG. 5, a guide surface 59 is formed on the inner surface of the second opposing wall 58B, sloping inward from the tip end to the base end of the second opposing wall 58B. A similar guide surface 59 is also formed on the inner surface of the first opposing wall 58A. Guide surfaces are also formed on the outer surface (top surface) of the first pressing piece 57A and the outer surface (top surface) of the second pressing piece 57B. At the positions of the claw portions 55A and 55B, there are notches between the base ends of the side walls 56A and 56B and the base ends of the opposing walls 58A and 58B, and no bottom exists. The bottom of the wire holding portion 54 is located outside the claw portions 55A and 55B in the X direction.

[0109] 11, a virtual line passing through the center between the first side wall 56A and the second side wall 56B along the extending direction is defined as a center line CL. The tip of the first pressing piece 57A is located on the second side wall 56B side beyond the center line CL. The tip of the second pressing piece 57B is located on the first side wall 56A side beyond the center line CL.

[0110] As shown in FIG. 11 , an imaginary line passing through the center between the center line CL and the first side wall 56A and extending along the center line CL is designated as a first quarter line QL1, and an imaginary line passing through the center between the center line CL and the second side wall 56B and extending along the center line CL is designated as a second quarter line QL2. The tip of the first pressing piece 57A does not extend beyond the second quarter line. The tip of the second pressing piece 57B does not extend beyond the first quarter line. This increases the gap between the first claw portion 55A and the first opposing wall 58A and the gap between the second claw portion 55B and the second opposing wall 58B, making it easier to insert a thick linear member 30A.

[0111] In Figure 9, imaginary line L1 indicates the position of the inner surface of the first side wall 56A. Imaginary line L2 indicates the position of the inner surface of the second side wall 56B. Imaginary line L3 indicates the position of the center line CL. Imaginary line L4 indicates the position of the first quarter line QL1. Imaginary line L4 indicates the position of the second quarter line QL2.

[0112] When the linear member 30 is inserted through the upper opening, each of the claws 55A, 55B receives a force pushing in the linear member 30 and elastically deforms so that the upper opening becomes approximately the same diameter as the linear member 30. After the linear member 30 is inserted, each of the claws 55A, 55B elastically returns to its original shape, and the upper opening becomes smaller in diameter than the linear member 30.

[0113] The size of the linear member 30 may vary depending on the vehicle model or grade. For example, as shown in Fig. 10 , a large-diameter linear member 30A having a diameter equal to the distance between the side walls 56A, 56B and the opposing walls 58A, 58B may be inserted into the wire holding portion 54. Alternatively, a small-diameter linear member 30B having a diameter equal to half the distance between the side walls 56A, 56B and the opposing walls 58A, 58B may be inserted into the wire holding portion 54. Here, the two claws 55A, 55B are provided at positions offset in the extension direction (X direction) of the linear member 30, so that linear members 30A, 30B of different sizes can be easily held in the wire holding portion 54.

[0114] The wire holding portion 54 is located between the first wire fixing portion 60 and the second wire fixing portion 76 along the extension direction of the linear member 30. Here, the first wire fixing portion 60 and the second wire fixing portion 76 are spaced apart in both the X and Y directions. The wire holding portion 54 is located between the first wire fixing portion 60 and the second wire fixing portion 76 in both the X and Y directions.

[0115] The portion of the linear member 30 extending from the wire holding portion 54 to the first wire fixing portion 60 and the portion extending from the wire holding portion 54 to the second wire fixing portion 76 are curved in opposite directions. This allows the linear member 30 to be held in an S-shaped path using the wire holding portion 54, the first wire fixing portion 60, and the second wire fixing portion 76. The purpose of holding the linear member 30 in an S-shaped path may be, for example, to restrict the path of the linear member 30 to prevent interference between the linear member 30 and surrounding components. Alternatively, the purpose may be to restrict the path to prevent the bending radius of the linear member 30 from becoming smaller than the minimum bending radius. Alternatively, the purpose may be to absorb excess length by utilizing the fact that the path length of the linear member 30 is longer than when the first wire fixing portion 60 and the second wire fixing portion 76 extend along the shortest path.

[0116] Here, the wire holding portion 54 is located at approximately the same position as the second fixing portion 50B in the X direction, and is located between the second fixing portion 50B and the second wire fixing portion 76 in the Y direction. This prevents the linear member 30 from overlapping with the release hole RH of the second fixing portion 50B in a plan view.

[0117] Here, the linear member 30 is bent from the first claw portion 55A toward the first wire rod fixing portion 60 toward the first opposing wall 58A. The linear member 30 is bent from the second claw portion 55B toward the second wire rod fixing portion 76 toward the second opposing wall 58B. The linear member 30 may be bent from the first claw portion 55A toward the first wire rod fixing portion 60 toward the first side wall 56A. The linear member 30 may be bent from the second claw portion 55B toward the second wire rod fixing portion 76 toward the second side wall 56B.

[0118] Here, the first wire fixing portion 60 is provided on the protector body 41, and the second wire fixing portion 76 is provided on the cover 70. Both the first wire fixing portion 60 and the second wire fixing portion 76 may be provided on one of the protector 40 and the cover 70. By providing the second wire fixing portion 76 on the cover 70, the cover 70 is pressed downward from the linear member 30 at the position of the second wire fixing portion 76. This prevents the cover 70 from floating up.

[0119] <Effects, etc.> According to the wiring module 10 configured as described above, the protruding dimension of the insertion portion 52 is greater than the protruding dimension of the fixing portion 50. This allows the insertion portion 52 to be made longer, which makes it easier to visually recognize the insertion portion 52 and to position the tip of the insertion portion 52 in the hole 91 of the fixing target 90. This improves the ease of installation of the wiring module 10.

[0120] Furthermore, when a virtual plane formed by connecting the tip of the first inward surface 43a and the tip of the second inward surface 43b in the longitudinal direction of the fixed object 90 is defined as a reference plane VS1, the tip of the insertion portion 52 extends beyond the reference plane VS1. This allows the insertion portion 52 to be longer than the line connecting the tip of the first inward surface 43a and the tip of the second inward surface 43b when viewed from the longitudinal direction of the fixed object 90.

[0121] Furthermore, when a virtual plane that passes through the tip of the first inward surface 43a and is perpendicular to the protruding direction of the insertion portion 52 is defined as a reference plane VS2, if the tip of the insertion portion 52 exceeds the reference plane VS2, the insertion portion 52 can be made longer than the first inward surface 43a.

[0122] Furthermore, when a virtual plane that passes through the central axis of the fixed object 90 and is perpendicular to the protruding direction of the insertion portion 52 is defined as a reference plane VS3, if the tip of the insertion portion 52 exceeds the reference plane VS3, the insertion portion 52 can be made longer than the central axis of the fixed object 90.

[0123] The fixing portion 50 also has a first fixing portion 50A that is provided at the base end of the insertion portion 52 and is fixed to a first fixing hole 91 of the fixing target 90 into which the insertion portion 52 is inserted. This allows the protector 40 to be fixed to the fixing target 90 at the position of the insertion portion 52.

[0124] Furthermore, since the fixing portion 50 includes the first fixing portion 50A and the second fixing portion 50B, the protector 40 can be fixed to the fixing object 90 at multiple locations. Since the second fixing portion 50B is shorter than the insertion portion 52, the insertion portion 52 is inserted into the first fixing hole 91 before the first fixing portion 50A and the second fixing portion 50B. This allows the first fixing portion 50A and the second fixing portion 50B to be positioned relative to the fixing object 90 before being fixed.

[0125] Furthermore, the first fixing portion 50A, the second fixing portion 50B, and the leaf spring 53 are provided spaced apart from one another along the longitudinal direction of the fixing object 90. Fixing at multiple locations using the first fixing portion 50A and the second fixing portion 50B, and the leaf spring 53, make it easy to suppress rattling of the protector 40 relative to the fixing object 90.

[0126] Furthermore, the partition protrusion 47 and the insertion portion 52 protrude in opposite directions from the same location on the support portion 42. This makes it easier to determine the position of the insertion portion 52 based on the position of the partition protrusion 47 when viewing the protector 40 from the side on which the partition protrusion 47 is provided.

[0127] Furthermore, since the first fixing portion 50A is provided at the base end of the insertion portion 52, the protector 40 can be fixed to the fixing object 90 at the position of the insertion portion 52. Furthermore, since the insertion portion 52 is inserted into the first fixing hole 91 before the first fixing portion 50A, the first fixing portion 50A can be easily positioned to the fixing object 90 before being fixed. Furthermore, since the release hole RH is formed in the partition protrusion 47, the position of the release hole RH can be easily determined based on the position of the partition protrusion 47. Furthermore, since the multiple groups G1, G2 are separated by the partition protrusion 47, the linear transmission member 23 of the groups G1, G2 is prevented from covering the release hole RH.

[0128] [Note] Although the support portion 42 has been described above as supporting both the first section S1 and the second section S2, this is not a required configuration. The support portion 42 may support only one of the first section S1 or the second section S2. For example, the protector 40 may be provided in the middle of the first section S1 in the extension direction, and the support portion 42 may be configured to support only the first section S1.

[0129] The configurations described in the above embodiments and modifications can be combined as appropriate as long as they are not mutually contradictory. [Explanation of symbols]
