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

The arrangement structure of the wiring members of the present disclosure is as follows.

(1) A floor carpet placed on the indoor side of the vehicle's floor panel, a holding member placed on the indoor side of the floor carpet that partially covers the floor carpet, and wiring held by the holding member. The holding member includes: a top plate portion having an upper surface exposed indoors; a plurality of pillars provided below, an arrangement space is formed between the plurality of pillars below the top plate, the wiring member is arranged in the arrangement space, and the wiring member is arranged in the arrangement space, and the wiring member is arranged in the arrangement space, and The member has a wiring member arrangement structure that has a rigidity capable of maintaining the arrangement space when the top plate portion is stepped on by an occupant.

According to the wiring member arrangement structure (1), the wiring member can be added on the indoor side of the floor carpet using the holding member. Since the holding member is a member that is exposed indoors and also partially covers the floor carpet, adding wiring members to the holding member requires removing the floor carpet and adding the wiring member under the floor carpet. It is simpler than This allows wiring members to be easily added to the floor of the vehicle. Further, the holding member is disposed at the feet of the occupant and can be stepped on by the occupant. Even in this case, since the holding member has enough rigidity to maintain the placement space when the top plate portion is stepped on by the occupant, the load when stepped on by the occupant is less likely to be applied to the wiring member. Furthermore, since the top surface of the top plate is exposed to the interior of the vehicle, the occupant is less likely to feel uncomfortable when stepping on the top plate.

(2) In the wiring member arrangement structure of (1), the height of each of the plurality of pillar portions may be such that a gap can be formed above or below the wiring member. As a result, a gap is formed between the wiring member and the top plate portion or between the wiring member and the floor carpet, so that the load when stepped on by an occupant is less likely to be applied to the wiring member.

(3) In the wiring member arrangement structure of (1) or (2), marks may be provided to specify a plurality of routes in the arrangement space. With this, when the wiring member is arranged along any one of the plurality of routes, the mark can be used to indicate the route to be arranged. This makes it easier for the wiring member to be placed along the predetermined path with respect to the holding member.

(4) In the wiring member arrangement structure according to any one of (1) to (3), the wiring member passes through a first point and a second point that are different points on the holding member, and The portion between the first point and the second point may be a longer route than the shortest route connecting the first point and the second point. Thereby, the holding member can absorb the extra length generated in the wiring member.

(5) In the wiring member arrangement structure according to any one of (1) to (4), each of the plurality of pillar portions may have a cylindrical shape. Thereby, by bending the wiring member along the side surface of the column, it is possible to prevent the radius of curvature of the wiring member from becoming smaller than the radius of the column.

(6) In the wiring member arrangement structure according to any one of (1) to (5), the holding member includes a first convex portion having the top plate portion and a plurality of first convex portions protruding from the top plate portion. a base sheet; a second base sheet having a base plate portion and a plurality of second convex portions protruding from the base plate portion; the tip surface of the plurality of first convex portions and the plurality of second convex portions; The first base sheet and the second base sheet overlap each other in opposite directions so that the tip surfaces of It may also be a pillar part. Thereby, the wiring member is held between the first base sheet and the second base sheet.

(7) In the wiring member arrangement structure according to any one of (1) to (6), the holding member includes a base sheet including the top plate portion and the plurality of pillar portions protruding from the top plate portion. , a holding sheet having a holding plate portion in which a plurality of recesses corresponding to the plurality of columnar portions are formed, the base sheet and the holding sheet such that the tips of the plurality of columnar portions fit into the plurality of recesses. may be attached. Thereby, the wiring member is held between the base sheet and the holding sheet.

(8) In the wiring member arrangement structure according to any one of (1) to (7), the holding member includes the top plate portion, the plurality of pillar portions protruding from the top plate portion, and the plurality of pillar portions that protrude from the top plate portion. The column may also include a retaining piece provided at a distal end rather than a base end of each column part. Thereby, the retaining piece prevents the wiring member from coming off from between the plurality of pillar parts.

(9) In the wiring member arrangement structure according to any one of (1) to (8), the holding member includes a base sheet and a fixing member, and the base sheet connects the top plate portion and the top plate. and the plurality of pillar parts protruding from the plurality of pillar parts, and the fixing member has a wiring attachment part attached to the wiring member and a hole into which the pillar part is fitted, and the fixing member has a wiring attachment part attached to the wiring member and a hole into which the pillar part fits. It may also have a pillar attachment part attached to the pillar part. Thereby, the wiring member can be held on the base sheet by the fixing member while the wiring member is placed on the base sheet.

[Details of embodiments of the present disclosure]
A specific example of the arrangement structure of wiring members according to 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 indicated by the scope of the claims, and is intended to include all changes within the meaning and scope equivalent to the scope of the claims.

[Embodiment 1]
The wiring member arrangement structure 20 according to the first embodiment will be described below. FIG. 1 is a schematic plan view showing a wiring member arrangement structure 20 according to the first embodiment. FIG. 2 is a sectional view taken along line II-II in FIG. The front-back direction (FRONT, REAR), the left-right direction (LEFT, RIGHT), and the up-down direction (UP, LOW) shown in FIGS. 1 and 2 correspond to the front-back direction, the left-right direction, and the up-down direction of the vehicle 10. FIG. 3 is a perspective view showing the holding member 40 with the wiring member 70 attached. FIG. 4 is a plan view showing the holding member 40. FIG. 5 is an explanatory diagram showing how the wiring member 70 is held by the holding member 40.

The wiring member arrangement structure 20 includes a floor carpet 30, a holding member 40, and a wiring member 70.

The floor carpet 30 is placed closer to the interior of the vehicle than the floor panel 12 in the vehicle 10. The floor carpet 30 covers the entire portion of the floor panel 12 that becomes the floor of the vehicle interior, except for a certain area. The partial area not covered by the floor carpet 30 is not particularly limited, but may be, for example, an area where metal fittings for mounting the seat 14 are provided, an area where a center console is placed, etc. The front edge of the floor carpet 30 may reach, for example, the dash panel 13. The configuration of the floor carpet 30 is not particularly limited, and can be appropriately set from the configurations of known floor carpets 30.

The holding member 40 is placed closer to the room than the floor carpet 30. The holding member 40 partially covers the floor carpet 30. The holding member 40 has a portion exposed indoors. For example, the holding member 40 partially covers an area of the floor carpet 30 located in front of the seat 14.

The holding member 40 includes a top plate portion 41 and a plurality of pillar portions 42. The top plate portion 41 has an upper surface exposed indoors. The plurality of pillar parts 42 are provided below the top plate part 41. The plurality of pillar parts 42 are provided so as to be lined up in each of the first direction and the second direction, which are directions that intersect with each other in plan view. The plurality of pillar portions 42 may protrude from the top plate portion 41 or may be provided on a member different from the member having the top plate portion 41. The plurality of pillar parts 42 are provided between the floor carpet 30 and the top plate part 41. The plurality of column parts 42 are spaced apart from each other along the horizontal direction. An arrangement space is formed between the plurality of pillar parts 42. A top plate portion 41 is located above the arrangement space. A floor carpet 30 is located below the arrangement space. The pillar portion 42 is located on the side of the arrangement space. The wiring member 70 is arranged in the arrangement space. The holding member 40 has a rigidity capable of maintaining the arrangement space between the plurality of pillar parts 42 when the top plate part 41 is stepped on by an occupant.

Note that when the top plate portion 41 is stepped on by an occupant, the arrangement space is allowed to become somewhat smaller. The difference between the size of the placement space before it becomes smaller and the size of the placement space after it becomes smaller is called a space reduction amount. The upper limit of the space reduction amount may be any value as long as a strong force is not applied to the wiring member 70. The upper limit of the space reduction amount may be, for example, between 0% and 30%, between 0% and 20%, or between 0% and 10%.

The holding member 40 is separable from the floor carpet 30. The attachment structure between the holding member 40 and the floor carpet 30 is not particularly limited, and can be set as appropriate. For example, the holding member 40 and the floor carpet 30 may be attached using attachment fittings. In this case, at least one of the holding member 40 and the floor carpet 30 includes a mounting fitting. The holding member 40 and the floor carpet 30 may be attached via hook-and-loop fasteners.

In the present disclosure, the structure in which the holding member 40 holds the wiring member 70 is referred to as a wiring holding structure. The wiring holding structure is a structure for suppressing the wiring member 70 from falling off from the holding member 40. The wiring holding structure is not particularly limited and can be set as appropriate.

Here, the holding member 40 includes two base sheets 44. Of the two base sheets 44, the upper base sheet 44 is an example of a first base sheet, and the lower base sheet 44 is an example of a second base sheet. When it is necessary to distinguish the base sheet 44 disposed above, it may be referred to as a base sheet 44A. Hereinafter, in FIG. 5, the solid line base sheet 44A shows the state in which the wiring holding structure is formed by being combined with the lower base sheet 44, and the base sheet 44A shown in two-dot chain lines shows the state before being combined with the lower base sheet 44.

Each base sheet 44 includes a base plate portion 45 and a plurality of convex portions 46. The base sheet 44 is, for example, a molded product made of resin and molded using a mold so as to have a shape including a base plate portion 45 and a plurality of convex portions 46 .

A plurality of convex portions 46 protrude from the base plate portion 45. The base plate portion 45 connects the plurality of convex portions 46. The base plate portion 45 has a first main surface and a second main surface. Here, the protrusion 46 protrudes only from the first main surface, and does not protrude from the second main surface.

The two base sheets 44 are stacked in opposite directions. The two base sheets 44 are joined together such that the first principal surfaces from which the convex portions 46 protrude are opposed to each other. The holding member 40 is arranged such that the second main surface of the base plate portion 45 in the lower base sheet 44 faces the floor carpet 30. The holding member 40 is arranged so that the second main surface of the base plate portion 45 of the upper base sheet 44A is exposed indoors. Therefore, the base plate portion 45 of the base sheet 44A constitutes the top plate portion 41.

Here, the tip surfaces of the convex portions 46 of the two base sheets 44 are in full contact with each other. As a result, the convex portions 46 of the two base sheets 44 are combined to form the column portion 42. The height of each of the plurality of pillar parts 42 is such that a gap can be formed above or below the wiring member 70. The height of each of the plurality of pillar parts 42 is higher than the height of the wiring member 70. The wiring member 70 is not packed between one set of pillar parts 42. Even if the pillar portion 42 bends slightly in the vertical direction due to the force of the holding member 40 being stepped on, a strong force is not easily applied to the wiring member 70.

Since the convex portions 46 of the two base sheets 44 are combined to form the pillar portion 42, the path through which the wiring member 70 passes is vertically different from the case where only the convex portions 46 of one base sheet 44 form the pillar portion. spread in the direction.

The two base sheets 44 are joined. Such a joining mode is not particularly limited and can be set as appropriate. For example, the two base sheets 44 may be joined together using an adhesive or double-sided adhesive tape. Further, for example, the two base sheets 44 may be welded together. Preferably, the two base sheets 44 are removably joined.

The two base sheets 44 may be provided so that the tip surfaces of the convex portions 46 do not come into full contact with each other. For example, the convex portion 46 of the other base sheet 44 may be located above the passageway of one base sheet 44. Specifically, for example, the center of one protrusion 46 of the other base sheet 44 may be located at the center of the four protrusions 46 of one base sheet 44. At this time, one convex portion 46 of the other base sheet 44 may fit between the four convex portions 46 of one base sheet 44 . In this case, the two base sheets 44 may be joined by press-fitting the protrusions 46 of one of the base sheets between the protrusions 46 of the other. In addition, the tip end surface of one convex portion 46 of the other base sheet 44 may partially contact the tip surfaces of each of the four convex portions 46 of the one base sheet 44.

In each base sheet 44, as shown in FIG. 4, the plurality of convex portions 46 are provided so as to be lined up in each of the first direction and the second direction, which are directions that intersect with each other in plan view. In the example shown in FIG. 4, the first direction and the second direction are orthogonal to each other. The first direction and the second direction may intersect at an angle other than orthogonal (for example, 60 degrees). The plurality of convex parts 46 are connected to each other via the base plate part 45.

Each of the plurality of protrusions 46 has a cylindrical shape. Therefore, the columnar portion 42 where the convex portions 46 of the two base sheets 44 are combined also has a cylindrical shape. Although the radius of the cylinder is not particularly limited, it is preferably equal to or larger than the minimum bending radius set for the wiring member 70. In the example shown in FIG. 4, the dimension between one set of protrusions 46 is smaller than the thickness of the protrusions 46 (the diameter of the cylinder). The dimension between one set of protrusions 46 may be the same as or larger than the thickness of the protrusions 46 (the diameter of the cylinder).

The convex portion 46 has a rigidity that allows it to maintain its placement space without being crushed when stepped on. Here, the inside of the convex portion 46 is filled with resin constituting the base sheet 44. Therefore, the convex portion 46 has a solid cross section. This increases the rigidity of the base sheet 44. The convex portion 46 may have a hollow cross section.

The wiring member 70 supplies power to devices mounted on the vehicle 10, and sends signals from and to the devices. The wiring member 70 includes, for example, an electric wire or an optical fiber. The wiring member 70 has a transmission path for transmitting electricity or light. The wiring member 70 may have one or more transmission paths. When the wiring member 70 has a plurality of transmission paths, the plurality of transmission paths may be provided together in one composite cable. The plurality of transmission lines may be provided separately in a plurality of covered electric wires. In the example shown in FIG. 2, three covered wires each having one transmission path are provided.

An intermediate portion of the wiring member 70 is held by the holding member 40. One end and the other end of the wiring member 70 extend outside the holding member 40 and are connected to a device or the like. In the example shown in FIG. 1, the portion of the wiring member 70 that is held by the holding member 40 is provided so as to extend along one path. The portion of the wiring member 70 held by the holding member 40 may be provided so as to extend along a plurality of different paths. A connector 72 or the like may be provided at the end of the wiring member 70, as shown in FIG. Portions extending along a plurality of paths may be connected to different connectors 72.

A mark 48 is provided on the wiring member arrangement structure 20. Marks 48 specify multiple paths in the placement space. Here, the mark 48 is provided on the first main surface of the base plate portion 45 from which the convex portion 46 projects. Different marks 48 are provided for each passage so that the passages between the protrusions 46 can be identified. In the example shown in FIG. 4, alphabetical marks 48 are provided in order from A as first type marks 48 in a plurality of passages that are lined up along the second direction and extend in the first direction. Further, numerical marks 48 are provided in order from 1 as second type marks 48 in a plurality of passages that are lined up along the first direction and extend in the second direction. Thereby, the intersection between the passage extending in the first direction and the passage extending in the second direction can be specified using alphabets and numbers. For example, an intersection between a passage marked with the letter A and a passage marked with the number 2 can be referred to as an intersection A2. Note that as the mark 48, characters other than numbers and alphabets may be used.

For example, when arranging the wiring member 70 with respect to the base sheet 44, by indicating the mark 48 of a specific passage, the path of the wiring member 70 on the base sheet 44 can be kept constant when manufacturing multiple products of the same type. can be kept. Specifically, in the example shown in FIG. 4, the wiring member 70 enters the inside of the base sheet 44 from one outside of the passage numbered 6, and passes through the intersections A6, A2, D2, D5, B5, Through B6, the other passageway numbered 6 extends outwardly. Therefore, by indicating the mark 48 at the intersection where the wiring member 70 passes, the route of the wiring member 70 is kept constant.

The wiring member 70 passes through a first point and a second point that are different from each other in the arrangement space. Any two points through which the wiring member 70 passes can be defined as the first point and the second point. For example, two points of the wiring member 70 extending outward from the base sheet 44 may be defined as the first point and the second point.

Here, there is a portion of the wiring member 70 where the path between the first point and the second point is longer than the shortest path connecting the first point and the second point. Specifically, in FIG. 4, although the wiring member 70 passes through the intersection A6 and the intersection B6, the route between them is shorter than the shortest route (here, a straight line along the path numbered 2). It is a long route. Note that the shortest path on the base sheet 44 in the present disclosure is the shortest path passing between the convex portions 46, and is not necessarily linear. For example, in FIG. 4, although the route from the intersection A3 to the intersection B2 in the wiring member 70 is curved, it can be considered as the shortest route.

<Modified example of wiring holding structure>
The wiring holding structure may have a configuration different from the above configuration using two base sheets 44. Modifications of the wiring holding structure will be described below.

FIG. 6 is a front view showing a first modification of the wiring holding structure. FIG. 7 is an exploded perspective view showing a wiring holding structure according to a first modification. In the wiring holding structure according to the first modification, a holding member 140 is provided in place of the holding member 40. The holding member 140 includes a base sheet 144 and a holding sheet 50.

The base sheet 144 includes a top plate portion 141 and a plurality of pillar portions 142. The top plate portion 141 of the base sheet 144 is formed similarly to the base plate portion 45 of the base sheet 44 described above. The columnar portions 142 of the base sheet 144 are formed similarly to the convex portions 46 of the base sheet 44, except for the height dimension. Here, since one base sheet 144 is provided with the column portion 142, the height dimension of the column portion 142 of the base sheet 144 is larger than the height dimension of the convex portion 46 of the base sheet 44.

The holding sheet 50 has a flat holding plate portion 51. As shown in FIG. 7, a plurality of recesses 52 corresponding to the columnar parts 142 are formed in the holding plate part 51. Here, a through hole passing through the holding plate part 51 is formed as the recess 52 . The recess 52 may be a bottomed hole that does not penetrate the holding plate 51. A cylindrical frame portion may protrude from the holding plate portion 51 to form the recess portion 52. The column portions 142 are press-fitted into the recesses 52, and the holding sheet 50 is held on the base sheet 144.

For example, as shown in FIG. 7, the wiring member 70 is placed on the base sheet 144 with the surface of the top plate portion 141 from which the pillar portions 142 protrude facing upward, and the holding sheet 50 is attached to the base sheet 144. It will be done. In this case, the holding member 140 with the wiring member 70 is inverted and placed on the floor carpet 30 so that the surface of the top plate part 141 from which the column parts 142 protrude faces downward. Therefore, the route of the wiring member 70 when disposed on the base sheet 144 and the route of the wiring member 70 in the vehicle 10 are reversed to each other.

FIG. 8 is a sectional view showing a second modification of the wiring holding structure. FIG. 9 is an explanatory diagram showing how the wiring holding structure according to the second modification is manufactured. In the wiring holding structure according to the second modification, a holding member 240 is provided in place of the holding member 140. The holding member 240 includes the base sheet 144 and a retaining piece 54. The retaining piece 54 covers the upper part of the passage and prevents the wiring member 70 from coming off from the passage. In the example shown in FIG. 9, the retaining pieces 54 shown in solid lines indicate the state at the time of molding before forming the wiring holding structure, and the retaining pieces 54 drawn with two-dot chain lines indicate the state forming the wiring holding structure. The solid line retaining piece 54 projects upward from the column 142 and forms an opening into which the wiring member 70 can be inserted between it and the column 142 . The retaining piece 54 may be integrally molded with the base sheet 144. The base sheet 144 may be formed into a shape having a top plate portion 141, a column portion 142, and a solid line retaining piece 54. After the wiring member 70 is placed in the passage, the retaining piece 54 shown in solid line is hot pressed and deformed. As a result, the retaining piece 54 is in the state indicated by the two-dot chain line, and functions as the holding member 40.

FIG. 10 is a front view showing a third modification of the wiring holding structure. FIG. 11 is an exploded perspective view showing a wiring holding structure according to a third modification. In the wiring holding structure according to the third modification, a holding member 340 is provided in place of the holding member 40. The holding member 340 includes the base sheet 144 and the fixing member 56. The fixing member 56 is provided on the wiring member 70. The fixing member 56 has a wiring attachment portion 57 and a column attachment portion 58.

The wiring attachment part 57 is attached to the wiring member 70. The wiring attachment part 57 is not particularly limited as long as it can be attached to the wiring member 70, and can be set as appropriate. For example, the wiring attachment portion 57 may be a molded resin portion formed by insert molding using the wiring member 70 as an insert component. For example, the wiring attachment part 57 may have a plate part extending in the extending direction of the wiring member 70 and on which the wiring member 70 is arranged, and the plate part and the wiring member 70 may be joined. For such joining, for example, an adhesive tape or a binding band may be wrapped around the plate portion and the wiring member 70. Further, for example, the wiring attachment part 57 may be a crimping part in which a plate part is crimped so as to surround the wiring member 70.

The column attachment section 58 is attached to one of the plurality of column sections 142. The column attachment portion 58 is formed into a plate shape. A hole is formed in the column attachment portion 58. The column portion 142 fits into the hole. The size of the hole is made to correspond to the size of the pillar portion 142. For example, the diameter of the hole may be formed slightly smaller than the diameter of the column 142, and the column 142 may be press-fitted into the hole. The pillar attachment part 58 may be attached to the pillar part 142 facing the passage through which the wiring member 70 passes. The pillar attachment part 58 may be attached to the pillar part 142 facing the passageway in which the wiring member 70 extends linearly.

FIG. 12 is an explanatory diagram showing a fourth modification of the wiring holding structure. In the wiring holding structure according to the fourth modification, a holding member 440 is provided in place of the holding member 40. The holding member 440 includes the base sheet 144 and a retaining piece 60. The retaining piece 60 is provided at the tip of each of the plurality of column parts 142. The retaining piece 60 is provided so as to narrow the space between the plurality of column parts 142. An opening is provided between a pair of retaining pieces 60 provided on a pair of column parts 142 facing each other. As shown in FIG. 12, the wiring member 70 is inserted between the pair of pillars 142 through the opening. The size of the opening is preferably smaller than the diameter of the thinnest wiring member 70. Preferably, the retaining piece 60 is elastically deformable so that the opening expands when the wiring member 70 is inserted and returns to its original size after the wiring member 70 is inserted.

The retaining piece 60 may have a circular or rectangular shape that is larger than the pillar portion 142 in plan view. The retaining piece 60 may have a size such that it partially protrudes toward the passage from a portion of the periphery of the pillar portion 142 in plan view.

The retaining piece 60 may prevent the wiring member 70 from coming off in a passage that is not an intersection. The retaining piece 60 may prevent the wiring member 70 from coming off at the intersection. The retaining piece 60 may prevent the wiring member 70 from coming off both at the non-intersecting passage and at the intersection.

The retaining piece 60 may be provided integrally with the column portion 142 during molding of the base sheet 144. The retaining piece 60 may be provided after the pillar portion 142 is molded. For example, after a plate portion similar to the top plate portion 141 is once provided at the tip of the column portion 142, a slit is formed in a portion of the plate portion that covers the passage, so that the portion divided by the slit is prevented from falling out. It may also be a piece 60.

FIG. 13 is an explanatory diagram showing a fifth modification of the wiring holding structure. In the wiring holding structure according to the fifth modification, a holding member 540 is provided in place of the holding member 40. The holding member 540 includes the base sheet 144 and an elastic body 62. The elastic body 62 is provided so as to fill the passage between the plurality of column parts 142. The elastic body 62 is made of an elastic material such as rubber or elastomer. A slit 63 is formed in the elastic body 62. The slit 63 is open on the tip side of the column 142. The wiring member 70 is passed through the slit 63 and held by the elastic force of the elastic body 62. Thereby, the wiring member 70 is held between the plurality of pillars 142 by the elastic body 62.

In the example shown in FIG. 13, an accommodation space is formed in the elastic body 62. The accommodation space is wider than the slit 63. The accommodation space accommodates the wiring member 70. The accommodation space is connected to an end of the slit 63 on the opposite side to the outer surface of the elastic body 62. However, the elastic body 62 does not need to have a housing space formed therein.

FIG. 14 is a front view showing a sixth modification of the wiring holding structure. FIG. 15 is an explanatory diagram showing how the wiring holding structure according to the sixth modification is manufactured. In the wiring holding structure according to the sixth modification, a holding member 640 is provided in place of the holding member 40. The holding member 640 includes the base sheet 144 and a shrink film 64. The shrink film 64 covers the area where the plurality of pillars 142 are provided. Thereby, the wiring member 70 is held between the plurality of pillars 142 by the shrink film 64.

As shown in FIG. 15, the shrink film 64 before shrinking is, for example, a flat film larger than the top plate portion 141. The shrink film 64 is applied with external energy such as heat from the heating device 80 or the like while covering the tip of the column portion 142 and shrinks. As a result, a portion of the shrink film 64 enters the passage from between the pillar parts 142.

The structure for fixing the shrink film 64 to the base sheet 144 is not particularly limited and can be set as appropriate. For example, the shrink film 64 may be fixed to the base sheet 144 with adhesive or adhesive tape. A hot melt adhesive may be provided as adhesive. The hot melt adhesive may be heated together to adhere to the base sheet 144 during heating to shrink the shrink film 64. Further, for example, the shrink film 64 may be fixed to the base sheet 144 by fitting into the uneven shape of the base sheet 144 consisting of the pillar portions 142 and the passages, without using an adhesive or the like. The shrink film 64 may be fixed to the base sheet 144 by an overlap margin that is generated by covering the periphery of the base sheet 144 more than once.

In the example shown in FIG. 1, one holding member 40 is placed on the floor carpet 30. A plurality of holding members 40 may be arranged separately from each other on the floor carpet 30. In this case, the wiring members 70 may be arranged on all the holding members 40, or the wiring members 70 may be arranged on only some of the holding members 40. When the wiring member 70 is added in the future to the holding member 40 on which the wiring member 70 is not arranged, the wiring member 70 may be arranged. That is, in order to simplify the addition of the wiring member 70 in the future, the holding member 40 on which the wiring member 70 is not placed may be provided in advance.

<Effects, etc.>
According to the wiring member arrangement structure 20 configured as described above, the wiring member 70 can be added on the indoor side of the floor carpet 30 using the holding member 40. Since the holding member 40 is a member that is exposed indoors and also a member that partially covers the floor carpet 30, adding the wiring member 70 to the holding member 40 requires removing the floor carpet 30 and placing it under the floor carpet 30. This is simpler than adding the wiring member 70 to the top. Thereby, the wiring member 70 can be easily added to the floor of the vehicle 10. Further, the holding member 40 is disposed at the feet of the occupant and can be stepped on by the occupant. Even in this case, the holding member 40 has enough rigidity to maintain the placement space when the top plate portion 41 is stepped on by the occupant, so that the load when stepped on by the occupant is less likely to be applied to the wiring member 70. Further, since the upper surface of the top plate portion 41 is exposed into the interior of the vehicle, the occupant is less likely to feel uncomfortable when stepping on the top plate portion 41.

Furthermore, the height of each of the plurality of pillar portions 42 is such that a gap can be formed above or below the wiring member 70. As a result, a gap is formed between the wiring member 70 and the top plate portion 41 or between the wiring member 70 and the floor carpet 30, so that the load when stepped on by an occupant is less likely to be applied to the wiring member 70.

Additionally, marks 48 are provided to specify a plurality of routes in the arrangement space. Thereby, when the wiring member 70 is arranged along any one of the plurality of routes, the mark 48 can be used to indicate the route to be arranged. This makes it easier for the wiring member 70 to be placed along the predetermined path with respect to the holding member 40.

Further, the wiring member 70 passes through a first point and a second point which are different points on the holding member 40, and a portion of the wiring member 70 between the first point and the second point is located between the first point and the second point. The route is longer than the shortest route between two points. Thereby, the holding member 40 can absorb the extra length generated in the wiring member 70. For example, the wiring member 70 having the same length may be used in common among a plurality of vehicle models in which the length of the path in the vehicle 10 between the first end and the second end of the wiring member 70 is different. Even in this case, in vehicle models where the path length in the vehicle 10 between the first end and the second end of the wiring member 70 is long, the extra length of the wiring member 70 is absorbed, so that the extra length of the wiring member 70 is less likely to get in the way. .

Furthermore, each of the plurality of pillar portions 42 has a cylindrical shape. Thereby, by bending the wiring member 70 along the side surface of the column 42, it is possible to prevent the radius of curvature of the wiring member 70 from becoming smaller than the radius of the column 42. For example, a minimum bending radius may be set for the wiring member 70. In this case, it is recommended to avoid placing the wiring member 70 bent with a radius of curvature smaller than the minimum bending radius. By arranging the wiring member 70 in a curved manner along the side surface of the column portion 42 whose radius is greater than or equal to the minimum bending radius, the wiring member 70 is arranged in a curved manner with a radius of curvature smaller than the minimum bending radius. is suppressed.

Furthermore, when the holding member 40 including two base sheets 44 is used, the wiring member 70 is held between the two base sheets 44.

Further, when the holding member 140 including the base sheet 144 and the holding sheet 50 is used, the wiring member 70 is held between the base sheet 44 and the holding sheet 50.

Furthermore, when the holding member 240 including the base sheet 144 and the retaining piece 54 is used, the retaining piece 54 prevents the wiring member 70 from coming off between the plurality of pillars 42 .

Furthermore, when the holding member 340 including the base sheet 144 and the fixing member 56 is used, the wiring member 70 can be held on the base sheet 144 by the fixing member 56 while the wiring member 70 is placed on the base sheet 144.

[Additional notes]
A part of the wiring member 70 extending from the holding member 40 (hereinafter referred to as the outside portion of the mat) may be placed on the floor carpet 30 in an area where the holding member 40 is not placed. A protection member of a different type than the holding member 40 may be provided on the outer portion of the mat.

Note that the configurations described in each of the above embodiments and modified examples can be combined as appropriate as long as they do not contradict each other.
