Description

Technical Field

[0001] The present disclosure relates to a wiring module. Background Art

[0002] A grommet is usually mounted on a wiring component that connects a vehicle door to a vehicle body. As an assembly structure between the grommet and a door panel, there are a structure in which the grommet passes through a through-hole formed in the door panel as described in Patent Document 1 and a structure in which the grommet is arranged along the surface of the door panel as described in Patent Document 2. The grommet described in Patent Document 2 does not need to pass through a through-hole formed in the door panel like the grommet described in Patent Document 1, and is therefore also referred to as a non-through grommet or the like.

[0032] [Description of Embodiments of the Present Disclosure]

[0033] First, embodiments of the present disclosure will be listed and described.

[0034] The wiring module of the present disclosure is as follows.

[0035] (1) A wiring module includes: a wiring component that connects between a vehicle body and a door panel; and a grommet that is mounted on the wiring component. The grommet includes a base portion that is fixed to a fixed position relative to the door panel. The wiring component includes a first section and a second section that is located closer to the vehicle body side than the first section and is covered by the base portion. The first section of the wiring component is covered by a protection portion that can deform by at least one of bending deformation and telescopic deformation. When the position where the grommet is assembled to the door panel changes, the length of the section of the wiring component that extends from the grommet toward the inner panel portion of the door panel changes, or the bent section within the section that extends from the grommet toward the inner panel portion of the door panel changes. Even in this case, the first section of the wiring component is covered by the protection portion that can deform by at least one of bending deformation and telescopic deformation. Therefore, even when the position where the grommet is assembled to the door panel changes, the difference in this position can be absorbed by the deformation of the protection portion, and the versatility of the wiring module can be improved.

[0036] (2) Based on the wiring module in (1), it is preferable that the protection portion is formed in a cylindrical shape. Thereby, the entire periphery of the first section can be covered by the protection portion, and the protection performance of the first section is improved.

[0037] (3) Based on the wiring module in (1) or (2), it is preferable that the protection portion is formed in a corrugated shape along the length direction and can deform by both bending deformation and telescopic deformation. Thereby, it is easy to cope with the difference in the position where the grommet is assembled to the door panel.

[0038] (4) Based on the wiring module in any one of (1) to (3), it is preferable that the protection portion is provided as a part of the grommet so as to extend from the base portion. Thereby, the protection portion does not need to be a separate component from the grommet, and an increase in the number of parts can be suppressed.

[0039] (5) Based on the wiring module in any one of (1) to (3), it is possible that the wiring module further includes a protection component, which is a component separate from the grommet and includes the protection portion. Thus, the protection portion can be made separate from the grommet, and the shape of the grommet can be prevented from becoming complicated.

[0040] (6) Based on the wiring module in any one of (1) to (5), it is possible that the wiring module further includes a protector, which is formed to have a higher rigidity than the grommet and is mounted on the grommet. The protector includes a base mounting portion mounted on the base portion. The base portion has a substrate portion extending along the door panel and a rib protruding from the side facing the door panel of the substrate portion. The base mounting portion is formed in a flat plate shape corresponding to the substrate portion. The base mounting portion and the base portion are mounted by a rib portion formed on one of the outer peripheral surface of the base mounting portion and the inner peripheral surface of the rib in the base portion being inserted into a groove formed on the other of the outer peripheral surface of the base mounting portion and the inner peripheral surface of the rib in the base portion. Thus, the protector can be simply mounted on the base portion.

[0041] (7) Based on the wiring module in (6), it is possible that the grommet further includes a cylindrical connecting portion connecting the base portion and the protection portion, and the protector further includes a cylindrical portion, which is provided at a part of the periphery of the base mounting portion and is inserted into the connecting portion. Thus, when the protection portion is deformed, the protector is difficult to fall off from the grommet.

[0042] (8) Based on the wiring module in (7), it is possible that the cylindrical portion and the connecting portion are mounted by an annular convex portion formed on one of the outer peripheral surface of the cylindrical portion and the inner peripheral surface of the connecting portion being inserted into an annular concave portion formed on the other of the outer peripheral surface of the cylindrical portion and the inner peripheral surface of the connecting portion. Thus, the cylindrical portion and the connecting portion can be simply mounted.

[0043] (9) Based on the wiring module in any one of (1) to (8), it is possible that the wiring module further includes a fixing part for positioning the front end portion of the protection portion on the door panel. Thus, the base end portion of the protection portion is fixed to the door panel via the base portion, and the front end portion is fixed to the door panel via the fixing part. Thus, when fixing one of the base portion and the fixing part to the door panel first and then fixing the other of the base portion and the fixing part to the door panel, the protection portion is easily deformed.

[0044] (10) Based on the wiring module of (9), it is possible that the fixing part is a planar member extending along the inner panel portion of the door panel, and the planar member includes: a main board portion for holding the section of the wiring member extending along the inner panel portion; and a protection part mounting portion provided at a part of the periphery of the main board portion for mounting the front end portion of the protection part. The portion of the wiring member extending along the door panel is held by the grommet and the planar member. Thus, a state is achieved in which most of the portion of the wiring member extending along the door panel extends along a predetermined path, and the assemblability of the wiring member can be improved.

[0045] (11) Based on the wiring module of any one of (1) to (10), it is possible that the protection part can at least be elastically deformed, and when the protection part is at its natural length, a surplus length is generated in the section of the wiring member including the first section. Thus, the section including the first section has a size longer than the natural length of the protection part, and the wiring member can easily cope with the expansion and contraction of the protection part.

[0046] [Details of the Embodiments of the Present Disclosure]

[0047] Specific examples of the wiring module of the present disclosure will be described below with reference to the drawings. It should be noted that the present disclosure is not limited to these examples, but is represented by the claims and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0048] [Embodiment 1]

[0049] Hereinafter, the wiring module of Embodiment 1 will be described.

[0050] <Door>

[0051] First, refer to Figure 1 and describe the door in the vehicle. Figure 1 FIG. is a schematic top view showing the wiring module 20 of Embodiment 1 and the door panel 12 to which the wiring module 20 is assembled.

[0052] The door 10 is formed in a flat shape as a whole and is provided in the vehicle in a manner that can be opened and closed to separate the interior of the vehicle from the exterior. Hereinafter, the open state and the closed state of the door 10 in the vehicle are simply referred to as the open state and the closed state. It is assumed that the door 10 is a driver's side door, a front passenger's side door, a rear seat door, etc. It should be noted that hereinafter, the door 10 is set as a side door for description. The door can also be a rear door, etc. And, the door 10 is set as a hinge door for description. The door can also be a sliding door, etc. The door 10 includes a door panel 12 and a wiring module 20.

[0053] The door panel 12 includes an outer panel 13 and an inner panel 14. The outer panel 13 is provided at a portion of the door 10 facing the outside of the vehicle and is a part that constitutes the appearance of the vehicle together with the vehicle body. The inner panel 14 is provided on the vehicle compartment side of the outer panel 13. The inner panel 14 has an inner plate portion 15 and a side plate portion 16. The inner plate portion 15 is a portion facing the vehicle compartment side in the closed state. A space for accommodating a window or electrical equipment or the like is provided between the inner plate portion 15 and the outer panel 13. For example, an opening is formed in the inner plate portion 15 to allow access to this space. The side plate portion 16 is a portion extending from the edge portion of the inner plate portion 15 toward the outer panel 13. In particular, here, the side plate portion 16 extends from the edge portion of the inner plate portion 15 located on the front side of the vehicle (the side where the hinge is present in the hinge door). The side plate portion 16 divides the space that can accommodate a window or electrical equipment or the like.

[0054] The wiring module 20 is assembled to the door 10. The wiring module 20 includes a wiring component 22 and a grommet 30. A protection portion 50 is provided in the wiring module 20. Here, the protection portion 50 is set and described as a part of the grommet 30. Moreover, here, the wiring module 20 includes a planar component 70.

[0055] The wiring component 22 is a component that supplies power to the equipment assembled to the door 10 or transmits signals between the equipment assembled to the door 10 and the equipment assembled to the vehicle body. Here, the wiring component 22 includes a plurality of electric wires 24. The wiring component 22 may also include an optical fiber cable or the like. The path and connection object of the wiring component 22 in the vehicle are not particularly limited, and paths and connection objects such as the following can be considered. That is, one end portion of the wiring component 22 is disposed on the vehicle body. A connector C1 is provided at one end portion of the wiring component 22. This connector C1 is connected to a vehicle body side connector provided on the vehicle body side wiring component extending from a battery, an electronic control unit, or the like. The other end portion of the wiring component 22 is disposed on the door 10. The other end portion of the wiring component 22 is connected to the equipment assembled to the door 10. The wiring component 22 and the equipment provided on the door 10 may also be connected by a connector, for example. In this case, a connector C2 can be provided at the other end portion of the wiring component 22.

[0056] The middle portion of the wiring component 22 is spanned between the vehicle body and the door 10. More specifically, the wiring component 22 extends from one end portion toward the other end portion, extends out from the through hole provided in the vehicle body, and extends toward the side plate portion 16 in the door panel 12. After the wiring component 22 reaches the side plate portion 16, it extends along the door panel 12 from the side plate portion 16 toward the inner plate portion 15.

[0057] The section of the wiring component 22 from the through-hole provided in the vehicle body to the inner panel portion 15 via the side panel portion 16 is covered and protected by the grommet 30. With respect to the portion of the wiring component 22 where the grommet 30 is provided, a plurality of electric wires 24 extend integrally. The section of the wiring component 22 from the side panel portion 16 to the inner panel portion 15 is covered by the base portion 32 and the protection portion 50 of the grommet 30. The wiring component 22 reaching the inner panel portion 15 extends from the protection portion 50. On the inner panel portion 15, the plurality of electric wires 24 branch and extend to the positions of the connected devices. The portion of the wiring component 22 extending from the protection portion 50 is held by the planar member 70. The planar member 70 holds the wiring component 22 in the branched path.

[0058] The grommet 30 is a so-called non-through grommet. The grommet 30 is assembled to cross a part of the peripheral edge of the inner panel 14 in the door panel 12. The grommet 30 is attached to the side panel portion 16. The grommet 30 includes a base portion 32. The base portion 32 is attached to the side panel portion 16. The base portion 32 is fixed to a fixed position with respect to the door panel 12. In the grommet 30, a protective cylinder portion 47 extends from the base portion 32 toward the vehicle body side. A vehicle body attachment portion 48 is provided at the front end of the protective cylinder portion 47. The vehicle body attachment portion 48 is fixed to the vehicle body. The protection portion 50 extends from the base portion 32 toward the rear end side of the door 10. The protection portion 50 can be deformed by at least one of bending deformation and telescopic deformation. When the wiring module 20 is fixed to the inner panel portion 15 and the side panel portion 16, sometimes due to the vehicle model, grade, etc., the length, relative position, etc. between the fixed position in the inner panel portion 15 and the fixed position in the side panel portion 16 change. By deforming the protection portion 50, the differences in the length, relative position, etc. between the fixed position in the inner panel portion 15 and the fixed position in the side panel portion 16 are absorbed.

[0059] Here, a protector 60 is attached to the grommet 30 (see Figure 7 ). The grommet 30 is a molded product based on an elastic material such as an elastomer and is easily deformed. The protector 60 is a molded product made of a material such as resin or metal and has a higher rigidity than the grommet 30. The protector 60 is attached to a portion of the grommet 30 that is desired to have a fixed shape and restricts the deformation of that portion.

[0060] The planar member 70 holds the portion of the wiring member 22 that extends from the protection portion 50. The planar member 70 is disposed inside the vehicle compartment of the vehicle door 10 at a position closer to the vehicle interior than the door panel 12. The planar member 70 is a member that extends in a planar shape with respect to the door panel 12. For example, the planar member 70 is disposed between the door panel 12 and the design trim in the vehicle door 10. The planar member 70 is a flat part that extends to the same extent as or larger than the opening formed in the inner panel portion 15. The planar member 70 is assembled to the door panel 12 so as to block the opening formed in the inner panel portion 15. The planar member 70 is assembled to the inner panel 14 by, for example, screw fastening, a locking structure, or the like. For example, if the portion of the peripheral edge of the planar member 70 that overlaps the inner panel 14 is fixed to the inner panel 14 by screw fastening or the like, the gap between them can be blocked as much as possible.

[0061] It should be noted that, in the vehicle door 10, in addition to the above-described devices to which the wiring member 22 is connected, for example, a weatherstrip WS and design trim (not shown) are also assembled.

[0062] The weatherstrip WS is assembled to the door panel 12 so as to extend along the peripheral edge. For example, Figure 1 The illustrated weatherstrip WS is assembled to the inner panel 14 so as to extend along the peripheral edge and surround the door panel 12. The weatherstrip WS has a portion that crosses the surface of the grommet 30. Generally, the weatherstrip WS is in a deformed state in which it is sandwiched and flattened by the vehicle body and the door panel 12 in the closed state. In the closed state, the grommet 30 supports the deformation of the portion of the weatherstrip WS that crosses the grommet 30.

[0063] The design trim is provided on the part of the vehicle door 10 facing the vehicle interior and is a part that constitutes the interior view of the vehicle. For example, a door handle, an operation part of in-vehicle equipment, or the like is mounted on the design trim. The portion of the wiring member 22 that extends from the grommet 30 and along the inner panel portion 15 and the planar member 70 are covered by the design trim.

[0064] Hereinafter, each part of the wiring module 20 will be described in detail. First, in addition to Figure 1 In addition, reference is also made to Figures 2 to 5 to describe the wiring member 22 in detail. Figure 2 is a perspective view showing the wiring module 20 of Embodiment 1. Figure 3 is a front view showing the wiring module 20 of Embodiment 1. Figure 4 is a rear view showing the wiring module 20 of Embodiment 1. Figure 5 is along Figure 3 is a cross-sectional view taken along the line V-V of

[0065] <Wiring Member>

[0066] The wiring component 22 has a first section, a second section, a third section, and a fourth section. The first section is the section covered by the protection part 50. The second section is located closer to the vehicle body side than the first section and is the section covered by the base part 32 of the grommet 30. The third section is the section covered by the protection cylinder part 47. Here, since the protection part 50 is provided as a part of the grommet 30, the first section, the second section, and the third section are the sections for installing the grommet 30. The fourth section is the section held by the planar component 70. Here, the first section to the fourth section are arranged in the order of the third section, the second section, the first section, and the fourth section from one end on the vehicle body side toward the other end on the door 10 side.

[0067] The cross-sectional shape of each section in the wiring component 22 can also be a shape corresponding to the installed position. For example, in the third section of the wiring component 22, a plurality of electric wires 24 are bundled together in such a way that the cross-sectional shape is as close as possible to a circular shape. Thereby, the third section of the wiring component 22 passing through the protection cylinder part 47 easily follows the deformation of the protection cylinder part 47. In the fourth section of the wiring component 22, the plurality of electric wires 24 are arranged along one direction (here, the vertical direction) to form a flat shape. Thereby, within the fourth section of the wiring component 22 held by the planar component 70, an increase in the height dimension from the door panel 12 is suppressed. In the first section, the plurality of electric wires 24 are bundled together in such a way that the cross-sectional shape of the plurality of electric wires 24 is closer to a flat shape than the third section and closer to a circular shape than the fourth section. Thereby, within the first section of the wiring component 22 covered by the protection part 50, an increase in the height dimension from the door panel 12 is suppressed as much as possible, and the wiring component 22 easily follows the deformation of the protection part 50. The second section of the wiring component 22 can be flat like the fourth section, can be bundled in a shape close to a circular shape like the third section, or can be bundled in a shape close to a flat shape like the first section. However, the cross-sectional shape of the wiring component 22 within each section can be set appropriately. For example, the cross-sectional shape of the wiring component can also be flat within the first section and the third section. And, for example, the cross-sectional shape of the wiring component can also be bundled in a shape close to a circular shape within the second section and the fourth section.

[0068] When the cross-sectional shape of the wiring component 22 is different in adjacent sections, the cross-sectional shape of the wiring component 22 changes at or near the boundary between the adjacent sections. For example, at the boundary between the first section and the fourth section, the shape of the wiring component 22 deforms between a shape in which the plurality of electric wires 24 are flattened and bundled and a shape in which the plurality of electric wires 24 are arranged in a line.

[0069] Next, in addition to Figures 1 to 5 other than that, with reference to Figures 6 to 11 the grommet 30 and the protector 60 will be described in detail. Figure 6 and Figure 7It is an exploded perspective view of the grommet 30 and the protector 60. Figure 6 and Figure 7 are perspective views observed from opposite orientations to each other. Figure 8 is along Figure 4 a sectional view taken along line VIII-VIII of Figure 9 is Figure 8 an enlarged view of region A1 of Figure 10 is Figure 9 an enlarged view of region A2 of Figure 11 is Figure 5 an enlarged view of region A3 of

[0070] <Grommet>

[0071] The grommet 30 includes a door mounting portion 31, a protective cylinder portion 47, and a vehicle body mounting portion 48. Moreover, the grommet 30 includes a protection portion 50 and a connecting portion 53 here.

[0072] The door mounting portion 31 is the part mounted on the door panel 12. The door mounting portion 31 is mounted on the side plate portion 16. The door mounting portion 31 includes a base portion 32, a flange 44, and a connecting portion 45.

[0073] The base portion 32 is formed flat. The base portion 32 is mounted in a manner of extending on the surface of the side plate portion 16. The base portion 32 includes a first base portion 33 and a second base portion 39.

[0074] The first base portion 33 has a substrate portion 34, ribs 37, and a rib portion 38. The substrate portion 34 is formed in a flat plate shape. In Figure 3 the example shown, the substrate portion 34 is pentagonal in shape, but it can also be other shapes. One surface of the substrate portion 34 faces the vehicle body side, and the other surface faces the door panel 12 side. A protective cylinder portion 47 is provided on one surface of the substrate portion 34. A through hole 35 is formed at the portion of the substrate portion 34 where the protective cylinder portion 47 is provided.

[0075] The through hole 35 communicates with the protective cylinder portion 47. The wiring component 22 passes from the other end side toward the one end side, passes through the other surface side of the substrate portion 34, and passes through the through hole 35 and is guided to the inside of the protective cylinder portion 47. In the substrate portion 34, a ring-shaped protrusion 36 is formed on the periphery of the through hole 35.

[0076] The annular protrusion 36 is formed such that the peripheral portion of the through-hole 35 in the substrate portion 34 protrudes toward the other surface side. The annular protrusion 36 is formed to have the same wall thickness as the other portions in the substrate portion 34. On one surface side of the substrate portion 34, the portion where the annular protrusion 36 is formed is recessed toward the other surface side compared to its surrounding portions. On the other surface side of the substrate portion 34, the portion where the annular protrusion 36 is formed protrudes toward the door panel 12 side compared to its surrounding portions.

[0077] The rib 37 is provided on the other surface of the substrate portion 34. The rib 37 protrudes from the substrate portion 34 toward the door panel 12 side. The height dimension of the rib 37 from the substrate portion 34 is of the same degree as the protruding dimension of the annular protrusion 36 in the substrate portion 34. In the substrate portion 34, the rib 37 is arranged to extend along the following path. That is, the rib 37 is not provided on one edge portion in the substrate portion 34 that corresponds to one side of the pentagon and is connected to the second base portion 39. The rib 37 is arranged to extend along the edge portions corresponding to the other four sides of the pentagon in the substrate portion 34 in most cases. The middle portion of the rib 37 is arranged to extend on the side closer to the one edge portion (the edge portion where the rib 37 is not provided) connected to the second base portion 39 than the through-hole 35. Thus, the rib 37 is formed into a shape in which the portion corresponding to one corner of the pentagon-shaped substrate portion 34 is recessed beyond the through-hole 35.

[0078] The ribbed portion 38 is provided on the inner peripheral surface of the rib 37. The ribbed portion 38 is provided over the entire length of the rib 37. The ribbed portion 38 is provided at a position along the middle portion in the height direction of the rib 37. The ribbed portion 38 is fitted into the groove 64 of the protector 60.

[0079] The second base portion 39 includes a substrate portion 40 and a support wall 41. The substrate portion 40 is formed in a flat plate shape. In Figure 3 the illustrated example, the substrate portion 40 has an isosceles trapezoid shape, but it may be other shapes. One surface of the substrate portion 40 faces the vehicle body side, and the other surface faces the door panel 12 side. One edge portion of the substrate portion 40 is connected to the substrate portion 34. A connecting portion 45 is provided on the edge portion of the substrate portion 40 opposite to the edge portion connected to the substrate portion 34.

[0080] The support wall 41 is provided on three edge portions of the substrate portion 40 except for the edge portion connected to the substrate portion 34. The support wall 41 protrudes from the substrate portion 40 toward the door panel 12 side. The protruding dimension of the support wall 41 gradually increases from the edge portion connected to the substrate portion 34 toward the edge portion where the connecting portion 45 is provided. The protruding dimension of the support wall 41 at the edge portion where the connecting portion 45 is provided is larger than the minor diameter of the connecting portion 45. A through-hole communicating with the connecting portion 45 is formed in the support wall 41. The support wall 41 inhibits the bending of the connecting portion 45 and the substrate portion 40 at the boundary.

[0081] The first base portion 33 and the second base portion 39 are connected via a hinge portion 42. The hinge portion 42 is a thin-walled portion compared to the substrate portions 34 and 40. The first base portion 33 and the second base portion 39 are easily bent at the hinge portion 42. By assembling the protector 60 on the grommet 30, the bending of the first base portion 33 and the second base portion 39 at the hinge portion 42 is restricted and maintained in a predetermined posture. The predetermined posture is a posture bent at the position of the hinge portion 42 in such a manner that the substrate portions 34 and 40 cross each other as shown in Figure 5 the posture shown in the figure, where the substrate portions 34 and 40 cross each other.

[0082] Mounting holes 43 are formed in the base portion 32. Bolts, clips, etc. are passed through the mounting holes 43. By fastening or clamping the bolts, clips, etc. passed through the mounting holes 43 to the door panel 12, the base portion 32 is assembled to the door panel 12. Here, two mounting holes 43 are formed in the base portion 32. The two mounting holes 43 are formed in the substrate portion 34 of the first base portion 33. The mounting holes 43 are provided on one of the two portions separated by the rib 37 in the substrate portion 34 that does not have the through hole 35. The two mounting holes 43 are separately provided on the upper and lower sides in the vertical direction with respect to the wiring component 22. The two mounting holes 43 are formed in such a manner that they are located on the same side (here, the outer side along the inside and outside directions of the vehicle) with respect to the weatherstrip WS.

[0083] A flange 44 is formed on the first base portion 33. The flange 44 is formed on the outer edge portion of the substrate portion 34. More specifically, as shown in Figure 4 the figure, the flange 44 is formed to project outward from the four edge portions of the substrate portion 34 other than the edge portion connected to the substrate portion 40. The flange 44 is formed as a thin-walled portion compared to the substrate portion 34. The flange 44 is provided on one surface side of the substrate portion 34. The flange 44 projects obliquely toward the door panel 12 side. The flange 44 projects more toward the door panel 12 side than the annular projecting portion 36 and the rib 37 in the first base portion 33. In a state where the grommet 30 is assembled to the door panel 12, the flange 44 elastically deforms along the door panel 12 and closely adheres to the door panel 12.

[0084] The flange 44 is also provided at the portion of the grommet 30 through which the weatherstrip WS passes. By providing the flange 44 at the portion of the grommet 30 through which the weatherstrip WS passes, as shown in Figure 9 the figure, the step between the door panel 12 and the grommet 30 becomes smaller. Thereby, it is difficult to generate a gap in the portion surrounded by the weatherstrip WS, the door panel 12, and the grommet 30. Here, the weatherstrip WS passes through on one surface of the substrate portion 34 on the indoor side of the portion where the through hole 35 is formed.

[0085] The connecting portion 45 is connected to the second base portion 39. The connecting portion 45 is provided at an edge portion of the second base portion 39 opposite to the edge portion connected to the hinge portion 42. The connecting portion 45 is connected to the protection portion 50. When the first base portion 33 and the second base portion 39 are bent due to the hinge portion 42, the connecting portion 45 and the protection portion 50 move integrally with the second base portion 39. The connecting portion 45 houses the cylindrical portion 66 of the protector 60. The connecting portion 45 is formed in a cylindrical shape with a flat cross-section. The connecting portion 45 is formed in a cylindrical shape having a cross-sectional shape of the same size as that of the large-diameter cylindrical portion 51 of the protection portion 50 described later. The connecting portion 45 is formed in a long size in the axial direction as compared with the large-diameter cylindrical portion 51. The connecting portion 45 is less deformable than the protection portion 50. An annular convex portion 46 is provided on the inner surface of the connecting portion 45.

[0086] The annular convex portion 46 is provided on the inner surface of the intermediate portion of the connecting portion 45 along the axial direction. The annular convex portion 46 is provided in an annular shape along the circumferential direction of the connecting portion 45. The annular convex portion 46 projects from the inner surface of the connecting portion 45 toward the center side of the connecting portion 45. The annular convex portion 46 is fitted into the annular concave portion 67 of the protector 60.

[0087] The protective cylinder portion 47 is provided to project from one surface of the first base portion 33. The protective cylinder portion 47 communicates with the through-hole 35. The protective cylinder portion 47 is formed to have flexibility. The structure for the protective cylinder portion 47 to have flexibility can be any structure. Here, the protective cylinder portion 47 is formed in a corrugated shape and has flexibility.

[0088] The vehicle body mounting portion 48 is provided at the other end portion of the protective cylinder portion 47. Here, the vehicle body mounting portion 48 is provided so as to be capable of being engaged with the through-hole formed in the vehicle body.

[0089] The protection portion 50 covers the first section of the wiring component 22. The protection portion 50 is formed to be capable of at least one of bending deformation and telescopic deformation. Here, the telescopic deformation means the deformation in which the protection portion 50 changes its length along its length direction. And, being capable of telescopic deformation means that it is sufficient to be capable of at least one of elongation deformation and contraction deformation, and preferably at least capable of elongation deformation. Being capable of telescopic deformation does not require both elongation deformation and contraction deformation.

[0090] Here, the protection portion 50 is provided as a part of the grommet 30. Therefore, the protection portion 50 is also provided with an elastic material such as an elastomer as the material. Thereby, the protection portion 50 can perform both bending deformation and telescopic deformation. That is, the protection portion 50 can be bent and telescopically deformed in terms of material. And, here the protection portion 50 is formed in a corrugated shape along its length direction and can perform both bending deformation and telescopic deformation. That is, the protection portion 50 can also be bent and telescopically deformed in terms of shape.

[0091] Here, the protection part 50 is formed in a cylindrical shape. Thus, the protection part 50 can cover the entire periphery of the wiring component 22. The protection part 50 is formed in a cylindrical shape with a flat cross-sectional shape. However, the shape of the protection part 50 is not limited to this and can be any shape. For example, the protection part 50 can also be formed in a cylindrical shape with a circular cross-sectional shape. Also, for example, the protection part 50 can be formed not in a cylindrical shape but in a sheet shape or a plate shape, etc. In this case, the sheet-shaped or plate-shaped protection part can be provided on either the door panel 12 side or the interior side of the vehicle, or on both sides, with respect to the wiring component 22.

[0092] The protection part 50 is a corrugated cylinder. The protection part 50 has a large-diameter cylinder part 51 and a small-diameter cylinder part 52 that are alternately continuous. The diameter of the protection part 50 changes periodically along the length direction.

[0093] The portion of the protection part 50 that undergoes bending deformation is defined as the bending part. The corrugated cylinder-shaped protection part 50 deforms as follows, for example, when undergoing bending deformation. That is, the interval between the large-diameter cylinder parts 51 adjacent to the inner peripheral side of the bending part becomes narrower, and the interval between the large-diameter cylinder parts 51 adjacent to the outer peripheral side of the bending part becomes wider.

[0094] The portion of the protection part 50 that undergoes elongation deformation is defined as the elongation part. The corrugated cylinder-shaped protection part 50 deforms as follows, for example, when undergoing elongation deformation. That is, it deforms in such a way that the connecting part between the large-diameter cylinder part 51 and the small-diameter cylinder part 52 approaches a straight line shape, or in such a way that the difference in diameter between the large-diameter cylinder part 51 and the small-diameter cylinder part 52 becomes smaller.

[0095] The portion of the protection part 50 that undergoes contraction deformation is defined as the contraction part. The corrugated cylinder-shaped protection part 50 deforms as follows, for example, when undergoing contraction deformation. That is, it deforms in such a way that the interval between adjacent large-diameter cylinder parts 51 becomes narrower or the diameter of the large-diameter cylinder part 51 becomes larger.

[0096] The section of the wiring component 22 that includes the first section covered by the protection part 50 can follow the deformation of the protection part 50. Each electric wire 24 can be bent and deformed, and the wiring component 22 including a plurality of electric wires 24 can also be bent and deformed. In particular, by bundling the plurality of electric wires 24, it is difficult to hinder the bending of each electric wire 24, and the wiring component 22 can easily follow the bending deformation of the protection part 50.

[0097] Further, when each electric wire 24 is a general electric wire, it is difficult to perform telescopic deformation in each electric wire 24. In this case, the wiring member 22 can follow the telescopic deformation of the protection part 50 as follows. That is, when the protection part 50 is at its natural length, a surplus length is provided in the section of the wiring member 22 including the first section. And when the protection part 50 elongates and deforms, by using this surplus length, the wiring member 22 can follow the elongation deformation of the protection part 50. The surplus length can be set, for example, by making the wiring member 22 longer than the shortest path or by loosely twisting to form a wire bundle. And when the protection part 50 contracts and deforms, by bending the wiring member 22 in such a way that it adopts a path longer than the path so far, the surplus length generated in the wiring member 22 can be absorbed.

[0098] A connecting part 53 is provided at the front end of the protection part 50. The connecting part 53 is a part for mounting the planar member 70. The connecting part 53 is formed in a cylindrical shape having a cross-sectional shape same as that of the large-diameter cylinder part 51. The connecting part 53 is formed to be long in the axial direction compared with the large-diameter cylinder part 51. The connecting part 53 is more difficult to deform compared with the protection part 50.

[0099] <Protector>

[0100] The protector 60 includes a base mounting part 61. The base mounting part 61 is a part for mounting on the base part 32. Here, the protector 60 further includes a cylindrical part 66. The cylindrical part 66 is a part for mounting on the connecting part 45. Mounting the base mounting part 61 on the base part 32 and mounting the cylindrical part 66 on the connecting part 45 forms a state where the protector 60 is mounted on the grommet 30.

[0101] The base mounting part 61 has a first flat part 62 and a second flat part 63. The first flat part 62 is disposed on the first base part 33. The first flat part 62 is formed in a flat plate shape. The planar shape of the first flat part 62 is a shape corresponding to the shape of the part surrounded by the rib 37, and is formed here in a concave shape with a corner of a pentagonal shape recessed. The through hole 35 is located at the position of the concave part of the first flat part 62. The first flat part 62 overlaps with the substrate part 34 of the first base part 33 in such a way as not to block the through hole 35. One edge part of the first flat part 62 is connected to the second flat part 63. Grooves 64 are formed on the outer peripheral surface of the other edge parts of the first flat part 62 except this edge part. And mounting holes 65 are formed in the first flat part 62. The mounting holes 65 are formed at positions overlapping with the mounting holes 43 formed in the first base part 33. Bolts, clips, etc. passing through the mounting holes 43 pass through the mounting holes 65. The mounting holes 43 and 65 are formed with their central axes aligned.

[0102] The second flat plate portion 63 is disposed on the second base portion 39. The second flat plate portion 63 is formed in a flat plate shape. The planar shape of the second flat plate portion 63 is formed in an isosceles trapezoid shape. One edge portion of the second flat plate portion 63 is connected to the first flat plate portion 62. A cylindrical portion 66 is provided at an edge portion of the second flat plate portion 63 on the side opposite to the edge portion connected to the first flat plate portion 62. A groove is formed in the second flat plate portion 63. The groove is formed on the surface of the second flat plate portion 63 facing the door panel 12 side. The groove is formed so as to connect the edge portion of the second flat plate portion 63 connected to the first flat plate portion 62 and the edge portion provided with the cylindrical portion 66.

[0103] In the base mounting portion 61, the first flat plate portion 62 and the second flat plate portion 63 are formed in a shape that extends and bends with their main surfaces crossing each other. By mounting the base mounting portion 61 on the base portion 32, the base portion 32 is maintained in a bent state. And, since the second section in the wiring component 22 also extends along the base mounting portion 61, it is maintained in a bent state. The base mounting portion 61 restricts the bending of the grommet 30 and the path of the wiring component 22.

[0104] The cylindrical portion 66 is received in the connecting portion 45. The cylindrical portion 66 is fitted into the connecting portion 45. The cylindrical portion 66 is formed in a cylindrical shape smaller than the connecting portion 45. The cylindrical portion 66 is formed in a flat cylindrical shape corresponding to the connecting portion 45. An annular recess 67 is formed on the outer peripheral surface of the cylindrical portion 66. An annular protrusion 46 formed on the inner peripheral surface of the connecting portion 45 is fitted into the annular recess 67. And, a connecting piece is provided outside the opening portion of the cylindrical portion 66. The connecting piece is formed so as to fill the gap between the surface of the second flat plate portion 63 facing the door panel side and the opening portion of the cylindrical portion 66. When the cylindrical portion 66 is inserted into the connecting portion 45, the connecting piece contacts a portion of the support wall 41 located at the periphery of the opening portion of the connecting portion 45, suppressing excessive insertion of both.

[0105] The wiring component 22 passes through the door panel 12 side and through the inside of the cylindrical portion 66 with respect to the protector 60 and the base mounting portion 61. As Figure 5 shown, the protector 60 is sandwiched at a portion of the grommet 30 on the door panel 12 side that is closer to the door panel 12 than the portion where the weatherstrip WS crosses. The protector 60 is located on the side of the weatherstrip WS closer than the wiring component 22. The protector 60 supports the deformation of the weatherstrip WS in the closed state.

[0106] <Installation of Grommet and Protector>

[0107] Here, the grommet 30 and the protector 60 can be assembled after being separately formed. Refer to Figures 12 to 14 and describe in detail the situation of installing the grommet 30 and the protector 60. Figures 12 to 14 is an explanatory diagram showing the situation of installing the grommet 30 and the protector 60.

[0108] First, as shown in Figure 12 , insert the cylindrical portion 66 of the protector 60 into the connecting portion 45 of the grommet 30. At this time, in the example shown in Figure 12 , the grommet 30 is in a posture of being opened with the substrate portions 34 and 40 parallel. In this way, when the substrate portions 34 and 40 of the grommet 30 are in a state of being opened more outward than the predetermined bending posture, it is easy to insert the cylindrical portion 66.

[0109] When inserting the cylindrical portion 66 into the connecting portion 45, the front end of the cylindrical portion 66 contacts the annular convex portion 46. Then, the portion of the annular convex portion 46 in the grommet 30 expands in diameter, and the insertion of the cylindrical portion 66 continues as it is. And when the annular concave portion 67 reaches the position of the annular convex portion 46, the portion of the annular convex portion 46 in the grommet 30 returns to its original state, and the annular convex portion 46 is fitted into the annular concave portion 67. The cylindrical portion 66 and the connecting portion 45 are installed by the annular convex portion 46 formed on the inner peripheral surface of the connecting portion 45 being fitted into the annular concave portion 67 formed on the outer peripheral surface of the cylindrical portion 66. Thus, as shown in Figure 13 , the cylindrical portion 66 is housed in the connecting portion 45, and the second flat portion 63 is in a state of being along the substrate portion 40 of the second base portion 39. And the first flat portion 62 of the protector 60 is in a state of being separated from the substrate portion 34 of the first base portion 33. In the mounted state of the connecting portion 45 and the cylindrical portion 66, when the connecting portion 45 is in a state of being elastically deformed in a slightly expanded manner by the cylindrical portion 66, it becomes a state where the connecting portion 45 fastens the cylindrical portion 66 by its restoring force, and the connecting portion 45 and the cylindrical portion 66 are difficult to come off and difficult to loosen.

[0110] Then, as shown in Figure 13 , when the first flat portion 62 approaches the substrate portion 34 of the first base portion 33, the grommet 30 bends at the hinge portion 42. The first base portion 33 in the grommet 30 and the portion on the side of the protective cylinder portion 47 closer to the first base portion 33 do not move in conjunction with the movement of the protector 60, and the second base portion 39 in the grommet 30 and the portion on the side of the protection portion 50 closer to the second base portion 39 move integrally with the protector 60. And when the first flat portion 62 approaches the substrate portion 34, the rib portion 38 of the rib 37 contacts the outer edge of the first flat portion 62. Then, the rib 37 bends in a manner of expanding outward with the base end portion of the substrate portion 34 as a reference, and the first flat portion 62 approaches the substrate portion 34 as it is. And when the groove 64 reaches the position of the rib portion 38, the portion of the rib 37 in the grommet 30 returns to its original state, and the rib portion 38 is fitted into the groove 64. The rib portion 38 formed on the inner peripheral surface of the rib 37 is fitted into the groove 64 formed on the outer peripheral surface of the base mounting portion 61, as shown in Figure 14Install the base mounting portion 61 and the base portion 32 as shown. In the installed state of the base portion 32 and the base mounting portion 61, when the base portion 32 is in a state of being elastically deformed in a slightly expanded manner due to the base mounting portion 61, a state is formed in which the base portion 32 fastens the base mounting portion 61 by its restoring force, and it becomes difficult for the base portion 32 and the base mounting portion 61 to come off and become loose.

[0111] Based on the above, a state is formed in which the protector 60 is installed on the grommet 30. In this state, as Figure 14 shown, the state in which the first base portion 33 and the second base portion 39 in the grommet 30 are bent at the hinge portion 42 is maintained.

[0112] <Planar member>

[0113] The planar member 70 extends along the inner panel portion 15 of the door panel 12. The planar member 70 is an example of a fixing part that fixes the front end portion of the protection portion 50 to the door panel 12. The planar member 70 is a molded product based on resin, metal, or the like. The planar member 70 has a main board portion 72 and a protection portion mounting portion 74.

[0114] The main board portion 72 holds the fourth section that extends along the inner panel portion 15 in the wiring member 22. The main board portion 72 is a portion that extends in a plate shape to such an extent that it can block the opening formed in the inner panel portion 15. For example, multiple parts of the peripheral edge portion of the main board portion 72 are assembled to the inner panel 14 by means such as screw fastening and locking structures. Here, the wiring member 22 is disposed on the surface of the main board portion 72 facing the vehicle interior side. The wiring member 22 may also be disposed on the surface of the main board portion 72 facing the vehicle exterior side. The wiring member 22 may also be disposed on both the surface of the main board portion 72 facing the vehicle interior side and the surface facing the vehicle exterior side. Hereinafter, the surface of the main board portion 72 on which the wiring member 22 is disposed is defined as the disposition surface 73. Here, the disposition surface 73 is flat. The disposition surface 73 may also be formed in an uneven shape. It is also possible that the portion of the disposition surface 73 that covers the opening is more recessed toward the vehicle exterior side and enters the opening than the portion that covers the periphery of the opening. It is also possible that the portion of the disposition surface 73 along the path where the wiring member 22 is disposed is flat. It is also possible that there is an uneven shape in a part of the path along which the wiring member 22 is disposed.

[0115] The protection part mounting part 74 is provided at a part of the periphery of the main board part 72. Here, the protection part mounting part 74 is provided at the periphery of the main board part 72 near the door hinge. The front end part of the protection part 50 is mounted on the protection part mounting part 74. Here, the protection part mounting part 74 extends forward (towards the door hinge) and downward from the main board part 72. The protection part mounting part 74 can also extend in any direction from the main board part 72. The protection part mounting part 74 is inserted into the connecting part 53. The protection part mounting part 74 is formed in a flat plate shape. The width dimension of the protection part mounting part 74 is formed to be the same as or smaller than the major-axis direction inner diameter of the part of the connecting part 53 where the annular convex part 54 is not provided. The width dimension of the protection part mounting part 74 is formed to be larger than the major-axis direction inner diameter of the part of the connecting part 53 where the annular convex part 54 is provided. Recesses 75 are formed at both side parts of the protection part mounting part 74 along the width direction. The annular convex part 54 of the connecting part 53 is fitted into the recesses 75 of the protection part mounting part 74, forming a state where the protection part mounting part 74 and the connecting part 53 are mounted. By assembling the planar member 70 to the inner panel 14, the state where the connecting part 53 mounted on the protection part mounting part 74 is located at a fixed position with respect to the door panel 12 is maintained.

[0116] Both side parts of the protection part mounting part 74 along the width direction are formed to be thicker than the middle part. Thereby, the rigidity of both side parts of the protection part mounting part 74 mounted on the connecting part 53 is improved, and the path of the wiring member 22 in the middle part through which the wiring member 22 passes is prevented from becoming narrow. The protection part mounting part 74 can also be formed in a cylindrical shape like the cylindrical part 66.

[0117] <Mounting of Cable Gland and Planar Member>

[0118] Here, the cable gland 30 and the planar member 70 can be assembled after being separately formed. Figure 15 and Figure 16 is an explanatory diagram showing the case of mounting the cable gland 30 and the planar member 70. In Figure 15 and Figure 16 a part of the cable gland 30 is shown as a sectional view.

[0119] First, as Figure 15As shown, the protection part mounting part 74 of the planar part 70 is inserted into the connection part 53 of the grommet 30. When the protection part mounting part 74 is inserted into the connection part 53, the front end of the protection part mounting part 74 contacts the annular convex part 54. Then, the diameter of the part of the annular convex part 54 in the connection part 53 expands, and the insertion of the protection part mounting part 74 continues as it is. And when the recess 75 reaches the position of the annular convex part 54, the part of the annular convex part 54 in the connection part 53 returns to its original state, and the annular convex part 54 is fitted into the recess 75. The protection part mounting part 74 and the connection part 53 are mounted by the annular convex part 54 formed on the inner peripheral surface of the connection part 53 being fitted into the recess 75 formed on the outer peripheral surface of the protection part mounting part 74. Thus, as Figure 16 shown, a state is formed in which the protection part mounting part 74 is housed in the connection part 53. In the mounted state, when the connection part 53 is in a state of being elastically deformed in a slightly expanded manner due to the protection part mounting part 74, a state is formed in which the connection part 53 fastens the protection part mounting part 74 by its restoring force, and the connection part 53 and the protection part mounting part 74 are difficult to come off and difficult to loosen.

[0120] <Assembly of Wiring Module to Door Panel>

[0121] Figure 17 is an explanatory diagram showing an example of the assembly of the wiring module 20 to the door panel 12. In Figure 17 the example shown, for easy understanding, the main parts are extracted and described, and the protection part 50 is shown by a double-dot dash line. And in Figure 17 the example shown, it is described that the assembly positions of the grommets 30 are changed while the assembly positions of the planar parts 70 are the same with respect to the three door panels 12A, 12B, and 12C, and the explanation is made as follows.

[0122] For example, in Figure 17 the assembly position of the grommet 30 shown by the solid line is the standard assembly position set in the wiring module 20, and the assembly position of the grommet 30 shown by the double-dot dash line is an assembly position shifted from the standard assembly position. At this time, by at least one of bending deformation and telescopic deformation of the protection part 50, the assembly position shifted from the standard assembly position can be accommodated. Thus, the difference in the assembly position of the grommet 30 that may vary due to differences in vehicle models, grades, etc. can be accommodated.

[0123] In Figure 17In the example shown, as the assembly position offset from the standard assembly position, an assembly position offset upward and forward from the standard assembly position and an assembly position offset downward and rearward from the standard assembly position are shown. Of course, this assembly position offset from the standard assembly position is an example, and other cases can also be dealt with. As the direction in which the assembly position is offset from the standard assembly position, the front-rear direction, left-right direction, up-down direction of the vehicle, and all directions combining these are envisioned.

[0124] <Effects of Embodiment 1, etc.>

[0125] When the position where the grommet 30 is assembled to the door panel 12 changes, the length of the section in the wiring member 22 extending from the grommet 30 toward the inner panel portion 15 changes, or the section bent within the section extending from the grommet 30 toward the inner panel portion 15 changes. According to the wiring module 20, the first section of the wiring member 22 is covered by the protection portion 50 capable of at least one of bending deformation and telescopic deformation. Therefore, even when the position where the grommet 30 is assembled in the door panels 12A, 12B, and 12C changes, the difference in this position can be absorbed by the deformation of the protection portion 50, and the versatility of the wiring module 20 can be improved.

[0126] Moreover, the protection portion 50 is formed in a tubular shape. Thereby, the entire periphery of the first section can be covered by the protection portion 50, and the protection performance of the first section is improved.

[0127] Moreover, the protection portion 50 is formed in a wrinkled shape along its length direction and can perform both bending deformation and telescopic deformation. Thereby, it is easy to cope with differences in the position where the grommet 30 is assembled to the door panel 12.

[0128] Moreover, the protection portion 50 is provided as a part of the grommet 30 so as to extend from the base portion 32. Thereby, the protection portion 50 can be prevented from being a separate component from the grommet 30, and an increase in the number of parts can be suppressed.

[0129] Moreover, the base mounting portion 61 and the base portion 32 are mounted by fitting the rib 37 formed on the inner peripheral surface of the base portion 32 into the groove 64 formed on the outer peripheral surface of the base mounting portion 61. Thereby, the protector 60 and the base portion 32 can be simply mounted.

[0130] Moreover, the protector 60 further includes a tubular portion 66, which is provided at a part of the periphery of the base mounting portion 61 and is fitted into the connecting portion 45. Thereby, when the protection portion 50 deforms, the protector 60 is difficult to come off from the grommet 30.

[0131] Further, the cylindrical portion 66 and the connecting portion 45 are mounted by fitting a ring-shaped convex portion 46 formed on the inner peripheral surface of the connecting portion 45 into a ring-shaped concave portion 67 formed on the outer peripheral surface of the cylindrical portion 66. Thus, the cylindrical portion 66 and the connecting portion 45 are simply mounted.

[0132] Further, the front end portion of the protection portion 50 is positioned on the door panel 12 via a fixing member. Thus, the base end portion of the protection portion 50 is fixed to the door panel 12 via the base portion 32, and the front end portion is fixed to the door panel 12 via the fixing member. Thus, when either one of the base portion 32 and the fixing member is fixed to the door panel 12 first and then the other of the base portion 32 and the fixing member is fixed to the door panel 12, the protection portion 50 is likely to be deformed.

[0133] Further, the portion of the wiring member 22 extending along the door panel 12 is held by the grommet 30 and the planar member 70. Thus, most of the portion of the wiring member 22 extending along the door panel 12 is in a state of extending along a predetermined path, and the assemblability of the wiring member 22 can be improved.

[0134] Further, the protection portion 50 can be at least telescopically deformed, and when the protection portion 50 is at its natural length, a surplus length is generated in the section including the first section of the wiring member 22. Thus, the first section is sized longer than the protection portion 50 at its natural length, and the wiring member 22 can easily cope with the telescopic deformation of the protection portion 50.

[0135] [Modification Example]

[0136] Figure 18 FIG. is a perspective view showing a modification example of the wiring module 20 of Embodiment 1. So far, it has been described that the protection portion 50 is provided as a part of the grommet 30, but this is not an essential structure. As Figure 18 shown, the protection portion 50 may not be provided on the grommet 130. In this case, the protection member 150 including the protection portion 50 may be provided separately from the grommet 130. Thus, the protection portion 50 can be made non-integral with the grommet 130, and the shape of the grommet 130 can be prevented from becoming complicated.

[0137] In this case, the grommet 130 may also be formed in a shape obtained by omitting the protection portion 50 and the connecting portion 53 from the above-described grommet 30. The connecting portion 45 and the cylindrical portion 66 for housing the protector 60 may be formed on the grommet 130.

[0138] The protective member 150 can be made of an elastic material or a resin, just like the grommets 30 and 130. The protective member 150 can also be a corrugated pipe or the like. One end of the protective member 150 can be mounted on the grommet 130 or the protector 60. A protective member mounting portion can be provided on the grommet 130 or the protector 60. For example, the connecting portion 45 can be extended axially and the protective member 150 can be inserted into the connecting portion 45 from the side opposite to the protector 60, etc., so that the connecting portion 45 serves as the protective member mounting portion. The other end of the protective member 150 can be mounted on the planar member 70. It can also be mounted on the protective portion mounting portion 74 of the planar member 70 by providing the above-mentioned connecting portion 53 on the protective member 150.

[0139] In addition, it has been described so far that the base mounting portion 61 and the base portion 32 are mounted by the rib 37 in the base portion 32. The protrusion 38 formed on the inner peripheral surface of the rib is inserted into the groove 64 formed on the outer peripheral surface of the base mounting portion 61, but this is not a necessary structure. The base mounting portion and the base portion can also be mounted by the protrusion formed on the outer peripheral surface of the base mounting portion being inserted into the groove formed on the inner peripheral surface of the rib in the base portion.

[0140] Furthermore, it has been described so far that the protector 60 includes the cylindrical portion 66 that is inserted into the connecting portion 45 of the grommet 30, but this is not a necessary structure. The protector can also include a plate-like mounting portion like the protective portion mounting portion 74 of the planar member 70 instead of the cylindrical portion 66. Also, the connecting portion of the grommet can be inserted into the inside of the cylindrical portion of the protector.

[0141] Moreover, it has been described so far that the cylindrical portion 66 and the connecting portion 45 are mounted by the annular protrusion 46 formed on the inner peripheral surface of the connecting portion 45 being inserted into the annular recess 67 formed on the outer peripheral surface of the cylindrical portion 66, but this is not a necessary structure. The cylindrical portion and the connecting portion can also be mounted by the annular protrusion formed on the outer peripheral surface of the cylindrical portion being inserted into the annular recess formed on the inner peripheral surface of the connecting portion.

[0142] In addition, it has been described so far that the wiring module 20 includes a fixing part, but this is not a necessary structure. The wiring module can also not include a fixing part. Also, it has been described that the fixing part is the planar member 70, but this is not a necessary structure. For example, the fixing part can also be a band clip or the like. The band clip can be wound around and mounted around the connecting portion 45.

[0143] It should be noted that the structures described in the above embodiments and various modification examples can be appropriately combined as long as they do not conflict with each other.
