Summary of the Invention
Problems to be Solved by the Invention
[0004] In addition to wires, a silencer and a carpet may be arranged on the floor panel. It is desired that the silencer and the carpet can be easily arranged on the floor panel.
[0005] Therefore, an object is to provide a technique that can easily arrange a silencer and a carpet on a floor panel.
Means for Solving the Problems
[0006] The floor wiring module of the present disclosure comprises a silencer, a carpet laminated on one main surface of the silencer, and a wiring member sandwiched and held between the silencer and the carpet, wherein the laminated region of the silencer and the carpet includes a first region where the silencer and the carpet are fixed by heat pressing, and a second region located on the one main surface adjacent to the first region and where the wiring member is located between the silencer and the carpet. [Effects of the Invention]
[0007] According to this disclosure, the silencer and carpet can be easily placed on the floor panel. [Brief explanation of the drawing]
[0008] [Figure 1] Figure 1 is a plan view showing a floor wiring module according to Embodiment 1. [Figure 2] Figure 2 is a cross-sectional view along the line II-II in Figure 1. [Figure 3] Figure 3 is a perspective view showing a manufacturing method for a floor wiring module. [Figure 4] Figure 4 is a perspective view showing a manufacturing method for a floor wiring module. [Figure 5] Figure 5 is a perspective view showing a method for manufacturing a floor wiring module. [Modes for carrying out the invention]
[0009] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described.
[0010] The floor wiring module of this disclosure is as follows:
[0011] (1) A floor wiring module comprising a silencer, a carpet laminated on one main surface of the silencer, and a wiring member sandwiched and held between the silencer and the carpet, wherein the laminated region of the silencer and the carpet includes a first region where the silencer and the carpet are fixed by heat pressing, and a second region located on the one main surface adjacent to the first region, and where the wiring member is located between the silencer and the carpet.
[0012] With this type of floor wiring module, the silencer and carpet are fixed by heating and pressing in the first region, allowing for relatively high adhesive force. As a result, the silencer and carpet are easily kept integrated in the floor wiring module, making it easy to place the silencer and carpet on the floor panel. Furthermore, since the second region adjacent to the first region is the wiring member placement region, the wiring members can be easily placed on the laminate of silencer and carpet, and the effects of heating and pressing in the first region are less likely to affect the wiring members.
[0013] (2) In the floor wiring module of (1), the laminated region may include a third region located adjacent to the second region on the one main surface, and to which the silencer and the carpet are fixed via a mechanical bonding member. This makes it easy to provide the third region. Furthermore, the first region, the second region, and the third region can be provided in this order, and the effects of heating and pressing in the first region are less likely to affect the wiring members.
[0014] (3) In the floor wiring module of (2), the area occupied by the first region on the one main surface may be larger than the area occupied by the third region. This makes it easier to maintain a state in which the silencer and the carpet are integrated.
[0015] (4) In the floor wiring module of (2) or (3), the first region may be located in a region of the vehicle floor that is more likely to be stepped on by occupants than the second and third regions. This makes it less likely for the wiring members in the second region and the mechanical joining members in the third region to be stepped on by occupants. In addition, since the silencer and the carpet are fixed in the first region by a heat press, it is easier to obtain strength against being stepped on by occupants.
[0016] (5) In any one of the floor wiring modules from (1) to (4), the second region may be provided with a wiring holding portion for fixing the wiring member to at least one of the silencer and the carpet. This suppresses misalignment between the wiring member and the laminate of the silencer and carpet.
[0017] In the floor wiring module of (6)(5), the wiring holding portion may be a holding portion having a mechanical joining member, or an adhesive holding portion having a fixing force weaker than the fixing force between the silencer and the carpet in the first region. This makes it easier to remove the wiring members even when it is necessary to remove the wiring members from the laminate of the silencer and carpet when repairing the floor wiring module.
[0018] (7) In any one of the floor wiring modules of (1) to (6), the carpet has a window located in a region inside the outer edge of the one main surface of the silencer, and the wiring member may have an end that extends onto the carpet through the window. This allows the wiring member to be easily connected to equipment located in a region inside the outer edge of the one main surface of the silencer.
[0019] (8) Further, the laminate for floor of the present disclosure includes a silencer and a carpet laminated on one main surface of the silencer, and the laminated region between the silencer and the carpet includes a fixed region where the silencer and the carpet are heat-pressed and fixed, and a separation region located adjacent to the fixed region on the one main surface and where the silencer and the carpet are separated, and is a laminate for floor.
[0020] According to such a laminate for floor, since the silencer and the carpet are heat-pressed and fixed in the fixed region, they can be fixed with a relatively high fixing force. Thereby, in the wiring module for floor, since the silencer and the carpet are easily kept in an integrated state, the silencer and the carpet can be easily arranged on the floor panel. Further, since the silencer and the carpet are separated in the separation region different from the fixed region, it is easy to arrange the wiring member between the silencer and the carpet.
[0021] (9) Further, the manufacturing method of the wiring module for floor of the present disclosure includes a step of heat-pressing and fixing a part of the laminated region between the silencer and the carpet, and a step of arranging a wiring member between the silencer and the carpet in another part of the laminated region where the silencer and the carpet are not fixed, and is a manufacturing method of a wiring module for floor.
[0022] According to such a manufacturing method of the wiring module for floor, since the silencer and the carpet are heat-pressed and fixed in a part of the laminated region, they can be fixed with a relatively high fixing force. Thereby, in the wiring module for floor, since the silencer and the carpet are easily kept in an integrated state, the silencer and the carpet can be easily arranged on the floor panel. Further, since the wiring member is arranged in a region different from the region where the silencer and the carpet are heat-pressed and fixed, the influence of the heat-pressing for fixing the silencer and the carpet hardly affects the wiring member.
[0023] [Details of the embodiments of this disclosure] Specific examples of the floor wiring modules, floor laminates, and methods for manufacturing floor wiring modules described herein will be explained below with reference to the drawings. However, this disclosure is not limited to these examples and is intended to include all modifications within the meaning and scope of the claims as indicated by the claims.
[0024] [Embodiment 1] The following describes the floor wiring module 10, the floor laminate 100, and the manufacturing method of the floor wiring module 10 according to Embodiment 1. Figure 1 is a plan view showing the floor wiring module 10 according to Embodiment 1. Figure 2 is a cross-sectional view along line II-II in Figure 1. The front-rear direction (FRONT, REAR), left-right direction (LEFT, RIGHT), and up-down direction (UP, LOW) shown in Figures 1 and 2 correspond to the front-rear direction, left-right direction, and up-down direction in a vehicle.
[0025] The floor wiring module 10 is positioned on the vehicle's floor panel 80. The floor panel 80 is located in the lower part of the passenger compartment. The floor panel 80 is, for example, a metal floorboard. The floor wiring module 10 comprises a silencer 20, a carpet 30, and wiring components 50.
[0026] The silencer 20 is a sound-insulating member placed on the floor panel 80. The silencer 20 may also be a member that flattens the unevenness of the floor panel 80. The silencer 20 is a molded body made of, for example, fiber or foamed resin. The silencer 20 may be thicker than the carpet 30. The silencer 20 may have higher rigidity than the carpet 30 and be able to maintain its shape.
[0027] The carpet 30 is placed on the silencer 20. The carpet 30 is usually exposed as a decorative surface inside the vehicle interior. The carpet 30 may have lower rigidity and be more easily bent compared to the silencer 20. The carpet 30 is laminated on one main surface of the silencer 20. The wiring member 50 is held in place sandwiched between the silencer 20 and the carpet 30. Here, the carpet 30 is divided in the front-rear direction of the vehicle.
[0028] The wiring member 50 connects equipment to each other in the vehicle. The wiring member 50 includes a plurality of linear transmission members 51. The linear transmission members 51 may be electric wires that transmit electricity or optical fiber cables that transmit light. The plurality of linear transmission members 51 may be bundled together according to their respective routes in the vehicle. The plurality of linear transmission members 51 may be bundled together with binding members such as adhesive tape or cable ties.
[0029] Here, a connector 52 is provided at the end of the linear transmission member 51. The linear transmission member 51 is connected to equipment or another wiring member 50 via the connector 52. The connector 52 has, for example, a connector 52 terminal and a connector 52 housing. The end of the linear transmission member 51 is connected to the connector 52 terminal. The connector 52 terminal is positioned and held in the connector 52 housing. The end of the linear transmission member 51 may also be connected directly to equipment or the like without going through the connector 52.
[0030] In this case, the wiring member 50 has a first extended portion 53, a second extended portion 54, and a third extended portion 55.
[0031] The first extending portion 53 extends along the longitudinal direction of the vehicle. A pair of first extending portions 53 are provided. The pair of first extending portions 53 are separated from each other in the width direction of the vehicle. One of the pair of first extending portions 53 extends along the left peripheral edge of the silencer 20, and the other of the pair of first extending portions 53 extends along the right peripheral edge of the silencer 20. The front end of the first extending portion 53 extends from the front end of the silencer 20 forward of the silencer 20. The rear end of the first extending portion 53 extends from the rear end of the silencer 20 rearward of the silencer 20.
[0032] The second extended portion 54 extends along the width direction of the vehicle. The second extended portion 54 is positioned in the middle of the silencer 20 along the extension direction of the first extended portion 53. The confluence of the first extended portion 53 and the second extended portion 54 is designated as a branching portion 56. The left end of the second extended portion 54 extends from the left end of the silencer 20 to the left of the silencer 20. The right end of the second extended portion 54 extends from the right end of the silencer 20 to the right of the silencer 20.
[0033] The third extended portion 55 branches off from the middle portion of the second extended portion 54 along its extending direction. The branching point 56 between the second extended portion 54 and the third extended portion 55 is located between the pair of first extended portions 53.
[0034] The layered region of the silencer 20 and the carpet 30 includes a first region 12, a second region 14, and a third region 16.
[0035] The first region 12 is the region where the silencer 20 and the carpet 30 are fixed together by heating and pressing. In this region, a heat-activated adhesive 40 is provided between the silencer 20 and the carpet 30. The silencer 20 and the carpet 30 are firmly fixed together via this heat-activated adhesive 40.
[0036] The second region 14 is located adjacent to the first region 12 on one main surface of the silencer 20. The dashed line in Figure 1 indicates the boundary between the first region 12 and the second region 14. The second region 14 is the region where the wiring member 50 is located between the silencer 20 and the carpet 30. In the second region 14, because the wiring member 50 is located between the silencer 20 and the carpet 30, at least one of the silencer 20 and the carpet 30 may bend or flex by the thickness of the wiring member 50. In the example shown in Figure 2, the silencer 20 is bent and the carpet 30 is bent. The carpet 30 may be prevented from bending by providing grooves in the silencer 20 or the like.
[0037] The second region 14 is provided with a wiring retaining portion 15 for fixing the wiring member 50 to at least one of the silencer 20 and the carpet 30. The wiring retaining portion 15 is a retaining portion having a mechanical joining member, or an adhesive retaining portion having a fixing force weaker than the fixing force between the silencer 20 and the carpet 30 in the first region 12.
[0038] If the wiring holding portion 15 is a holding portion having a mechanical joining member, such mechanical joining member may be an elastic member such as a sponge. When the elastic member is sandwiched between the wiring member 50 and the silencer 20 or carpet 30 and compressed, a frictional force is generated, and the wiring member 50 is held in place by this frictional force.
[0039] If the wiring holding portion 15 is an adhesive holding portion having a weaker adhesive force than the adhesive force between the silencer 20 and the carpet 30 in the first region 12, the adhesive holding portion may be a portion bonded using an adhesive member such as single-sided adhesive tape, double-sided adhesive tape, or adhesive. The adhesive holding portion may also be a portion where, without the use of other members, the resin of at least one of the wiring member 50 and the silencer 20 or carpet 30 melts and adheres to the other member, such as by fusion bonding. Figure 2 shows an example of an adhesive holding portion 15 having an adhesive member 60 such as double-sided adhesive tape or adhesive.
[0040] The wiring retaining parts 15 may be provided at multiple locations spaced apart along the extending direction of the wiring member 50 that can be placed on the silencer 20. In this case, the wiring retaining parts 15 may be provided at the portion where the wiring member 50 extends from the silencer 20, at the branching portion 56 of the wiring member 50, etc. The wiring retaining parts 15 may also be provided along the entire length of the wiring member 50 that can be placed on the silencer 20 along the extending direction.
[0041] The third region 16 is located adjacent to the second region 14 on one main surface of the silencer 20. The third region 16 is the region to which the silencer 20 and the carpet 30 are fixed via a mechanical fastening member 42. The mechanical fastening member 42 is not particularly limited and may be, for example, a tag pin-like member, a stapler, or sewing thread. The third region 16 includes the outer edge of the carpet 30. The third region 16 is connected to the first region 12 via the second region 14. The second region 14 is interposed between the first region 12 and the third region 16. The second region 14 and the third region 16 are free ends before the third region 16 is fixed.
[0042] Figure 2 shows an example of a tag pin-shaped member 42 as a mechanical joining member 42. The tag pin-shaped member 42 has, for example, a pair of support pieces 43 and a connecting piece 44 that connects the pair of support pieces 43. One of the pair of support pieces 43 is located below the lower surface of the silencer 20 and hooks onto the lower surface of the silencer 20. The other of the pair of support pieces 43 is located above the upper surface of the carpet 30 and hooks onto the upper surface of the carpet 30. The connecting piece 44 penetrates both the silencer 20 and the carpet 30.
[0043] The area occupied by the first region 12 on one main surface of the silencer 20 is greater than the area occupied by the third region 16. The area occupied by the first region 12 may also be greater than the area occupied by the second region 14. The area occupied by the first region 12 may also be greater than the sum of the areas occupied by the second region 14 and the third region 16. More than half of the area of one main surface of the silencer 20 may be occupied by the first region 12.
[0044] The first area 12 is positioned on the vehicle floor in an area that is more likely to be stepped on by the occupants than the second area 14 and the third area 16. An area that is more likely to be stepped on by the occupants is, for example, the area in front of the occupants' feet. An area that is less likely to be stepped on by the occupants is, for example, under the seats, on the sides of the rocker 82, etc.
[0045] In the carpet 30, the portion forming the first region 12 is designated as the first fixing portion 31, the portion forming the second region 14 is designated as the wiring covering portion 32, and the portion forming the third region 16 is designated as the second fixing portion 33. The wiring covering portions 32 are connected to the first fixing portion 31 of the carpet 30 located in front of the vehicle to the left, right, and rear. The left wiring covering portion 32 and the rear wiring covering portion 32 are separated by a slit 34A. The right wiring covering portion 32 and the rear wiring covering portion 32 are separated by a slit 34B. The rear wiring covering portion 32 is also separated to the left and right by a slit 34C. In the portion of the rear wiring covering portion 32 that covers the branching portion 56 between the first extended portion 53 and the second extended portion 54, tag pin-shaped members 42 are provided at four locations around the branching portion 56. The wiring cover portion 32 is connected to the left and right sides of the first fixing portion 31 of the carpet 30 located at the rear of the vehicle.
[0046] The carpet 30 has a window portion 35 located in a region inward from the outer edge of one main surface of the silencer 20. The wiring member 50 has an end that extends onto the carpet 30 through the window portion 35. Here, the end of the third extending portion 55 extends onto the carpet 30 through the window portion 35. The end of the third extending portion 55 is connected to equipment on the carpet 30. Such equipment may be equipment placed on a seat.
[0047] <Manufacturing method> Next, the manufacturing method of the floor wiring module 10 will be described with reference to Figures 3 to 5. Figures 3 to 5 are perspective views showing the manufacturing method of the floor wiring module 10.
[0048] First, as shown in Figure 3, a portion of the laminated area between the silencer 20 and the carpet 30 is heated and pressed to fix it in place. The carpet 30 is divided into two parts along the front-to-back direction. A slit 34 is formed in the front carpet 30. In Figure 3, the area of the carpet 30 that is heated and pressed is the area enclosed by the dashed line. Note that in Figure 3, the front carpet 30 and the rear carpet 30 are separated in the front-to-back direction. The front carpet 30 and the rear carpet 30 may be in contact in the front-to-back direction.
[0049] The heated press is performed using a heated press device 90. The heated press device 90 includes a pair of press members 91 and 92. Press member 91 presses against the carpet 30, and press member 92 presses against the silencer 20. For example, the heated press is performed with at least one of the pair of press members 91 and 92 heated by the heated device.
[0050] A heat-activated adhesive 40 is applied to the portion of the silencer 20 and carpet 30 that is to be fixed together. The portion of the silencer 20 and carpet 30 is heated and pressed, causing the silencer 20 and carpet 30 to be fixed together via the heat-activated adhesive 40. The portion of the silencer 20 and carpet 30 that does not have the heat-activated adhesive 40 applied to it may also be heated and pressed. In this case, the portion of the silencer 20 and carpet 30 that does not have the heat-activated adhesive 40 does not need to be fixed together when heated and pressed.
[0051] Next, in another part of the layered area between the silencer 20 and the carpet 30, where the silencer 20 and the carpet 30 are not fixed together, the wiring member 50 is placed between the silencer 20 and the carpet 30.
[0052] Here, as shown in Figure 4, a portion of the laminated area of the silencer 20 and the carpet 30 is fixed by heating and pressing to form the floor laminate 100. The floor laminate 100 comprises the silencer 20 and the carpet 30 laminated on one main surface of the silencer 20. In the floor laminate 100, the laminated area of the silencer 20 and the carpet 30 includes a fixed area 102 and a separated area 104. The fixed area 102 is the area where the silencer 20 and the carpet 30 are fixed by heating and pressing. The fixed area 102 corresponds to the first area 12 in the floor wiring module 10. The separated area 104 is located next to the fixed area 102 on one main surface of the silencer 20. The separated area 104 is the area where the silencer 20 and the carpet 30 are separated. The separated area 104 is the portion that becomes the second area 14 and the third area 16 in the floor wiring module 10.
[0053] In the carpet 30 forming the floor laminate 100, the portion forming the separation region 104 is a movable piece 36 whose tip can move freely around the base end, rather than the base end connected to the fixed region 102. The movable piece 36 can be bent with the base end connected to the fixed region 102 as the fold. In the carpet 30 at the front of the vehicle, slits 34A, 34B, and 34C are provided, thereby providing four movable pieces 36 to the left, right, left rear, and right rear of the fixed region 102. In the carpet 30 at the rear of the vehicle, movable pieces 36 are provided to the right and left of the fixed region 102, respectively.
[0054] In the separation region 104 of this floor laminate 100, a wiring member 50 is placed between the silencer 20 and the carpet 30.
[0055] First, as shown in Figure 4, the movable piece 36 is bent to expose the upper surface of the silencer 20. Then, the wiring member 50 is placed on the exposed upper surface of the silencer 20. At this time, the upper surface of the silencer 20 that is exposed by bending all of the movable pieces 36 will have a shape corresponding to the path of the wiring member 50. Therefore, by placing the wiring member 50 on the exposed upper surface of the silencer 20, the wiring member 50 can be easily positioned along a predetermined path. In the example shown in Figure 4, the movable piece 36 is bent at 90 degrees. The movable piece 36 may also be bent at 180 degrees and overlapped with the fixed area 102. The carpet 30 may be formed so that the movable piece 36 can be bent so that it overlaps with the fixed area 102.
[0056] In Figure 4, an adhesive member 60, such as double-sided adhesive tape or adhesive, is provided on the upper surface of the silencer 20. A wiring member 50 is placed on the upper surface of the silencer 20, and the wiring holding portion 15 is formed when the adhesive member 60 adheres to the silencer 20 and the wiring member 50.
[0057] Once the wiring member 50 has been placed on the exposed upper surface of the silencer 20, the movable piece 36 is returned to its original position. In the front of the two carpets 30, the movable piece 36 located behind the fixed area 102 may or may not be in contact with the rear of the two carpets 30. In this case, the ends of the first extended portion 53 and the second extended portion 54 are pulled out to the outside of the silencer 20. Also, the third extended portion 55 is pulled out onto the carpet 30 from between the two movable pieces 36 separated from each other by the slit 34C. The space between the two movable pieces 36 is the window portion 35. As a result, the wiring member 50 is placed between the silencer 20 and the carpet 30, resulting in the state shown in Figure 5. Note that the window portion 35 only needs to be able to allow a part of the wiring member 50 to be pulled out. For example, the window portion 35 may be slit-shaped if the portions of the two movable pieces 36 that are in front of the wiring member 50 and the portions that are behind the wiring member 50 are in contact in the left-right direction. Alternatively, the window portion 35 may be open if the two movable pieces 36 are separated in the left-right direction.
[0058] Next, the silencer 20 and carpet 30 are fixed to the side of the wiring member 50 within the separation region 104. Figure 5 shows an example of fixing the silencer 20 and carpet 30 by driving in a tag pin-shaped member 42 using a jig 94. The tag pin-shaped member 42 is fixed to the end of the movable piece 36 opposite to the fixed region 102. The floor wiring module 10 is manufactured by fixing the silencer 20 and carpet 30 via the tag pin-shaped member 42 at a predetermined location in the stacked region.
[0059] Alternatively, the floor wiring module 10 may be transported to a vehicle assembly plant and placed on the floor panel 80. Or, the floor laminate 100 may be transported to a vehicle assembly plant and placed on the floor panel 80, and the wiring members 50 may be placed on the floor laminate 100 on the floor panel 80 to form the floor wiring module 10.
[0060] <Effects, etc.> As described above, the floor wiring module 10 is fixed by heating and pressing the silencer 20 and carpet 30 in the first region 12, so it can be fixed with a relatively high fixing force. As a result, the silencer 20 and carpet 30 are easily kept in an integrated state in the floor wiring module 10, so the silencer 20 and carpet 30 can be easily placed on the floor panel 80. In addition, since the second region 14 adjacent to the first region 12 is the area for placing the wiring members 50, the wiring members 50 can be easily placed on the laminate of the silencer 20 and carpet 30, and the effect of heating and pressing in the first region 12 does not easily affect the wiring members 50.
[0061] Furthermore, the laminated region includes a third region 16 located next to the second region 14 on one main surface of the silencer 20, and to which the silencer 20 and the carpet 30 are fixed via a mechanical joining member 42. This allows the third region 16 to be easily provided. Also, the first region 12, the second region 14, and the third region 16 can be provided in this order, and the effect of the heating press in the first region 12 is less likely to affect the wiring member 50.
[0062] Furthermore, the area occupied by the first region 12 on one main surface of the silencer 20 is larger than the area occupied by the third region 16. As a result, the larger area of the first region 12, where the silencer 20 and the carpet 30 are fixed by the heat press, makes it easier to maintain a state in which the silencer 20 and the carpet 30 are integrated.
[0063] Furthermore, the first area 12 is positioned on the vehicle floor in an area that is more likely to be stepped on by occupants than the second area 14 and the third area 16. This makes it less likely for the wiring member 50 in the second area 14 and the mechanical joining member 42 in the third area 16 to be stepped on by occupants. In addition, since the silencer 20 and the carpet 30 are fixed in the first area 12 by a heated press, it is easier to obtain strength against being stepped on by occupants.
[0064] Furthermore, the second region 14 is provided with a wiring holding portion 15 that fixes the wiring member 50 to at least one of the silencer 20 and the carpet 30. This suppresses misalignment between the wiring member 50 and the laminate of the silencer 20 and the carpet 30.
[0065] Furthermore, the wiring holding portion 15 is either a holding portion via a mechanical joining member, or an adhesive holding portion having a weaker adhesive force than the adhesive force between the silencer 20 and the carpet 30 in the first region 12. This makes it easy to remove the wiring member 50 even when it is necessary to remove the wiring member 50 from the laminate of the silencer 20 and the carpet 30, such as when repairing the floor wiring module 10.
[0066] Furthermore, the carpet 30 has a window portion 35 located in a region inside the outer edge of one main surface of the silencer 20, and the wiring member 50 has an end that extends onto the carpet 30 through the window portion 35. This allows the wiring member 50 to be easily connected to equipment located in a region inside the outer edge of one main surface of the silencer 20.
[0067] Furthermore, with the floor laminate 100, the silencer 20 and carpet 30 are fixed by heating and pressing in the fixed area 102, so they can be fixed with a relatively high fixing force. As a result, the silencer 20 and carpet 30 are easily kept integrated in the floor wiring module 10, so the silencer 20 and carpet 30 can be easily placed on the floor panel 80. In addition, since the silencer 20 and carpet 30 are separated in a separate area 104 separate from the fixed area 102, the wiring member 50 can be easily placed between the silencer 20 and carpet 30.
[0068] Furthermore, according to the manufacturing method of the floor wiring module 10, the silencer 20 and carpet 30 are fixed by heating and pressing in a part of the laminated area, so they can be fixed with a relatively high fixing force. As a result, the silencer 20 and carpet 30 are easily kept in an integrated state in the floor wiring module 10, so the silencer 20 and carpet 30 can be easily placed on the floor panel 80. In addition, since the wiring member 50 is located in a separate area from the area where the silencer 20 and carpet 30 are fixed by heating and pressing, the effect of the heating press used to fix the silencer 20 and carpet 30 does not easily affect the wiring member 50.
[0069] [Note] Up to this point, the laminated region has been described as including the third region 16, but this is not an essential configuration. The laminated region does not have to include the third region 16. For example, the movable piece 36 of the carpet 30 may not be fixed in the vehicle. Alternatively, for example, the movable piece 36 of the carpet 30 may be fixed to a member other than the silencer 20 in the vehicle, so that the silencer 20 and the carpet 30 are sandwiched between the wiring member 50.
[0070] Furthermore, although it has been explained so far that a wiring retaining section 15 is provided in the second region 14, this is not an essential configuration. For example, the wiring retaining section 15 does not need to be provided in the second region 14.
[0071] Furthermore, although the wiring member 50 has been described as having an end that extends onto the carpet 30 through the window portion 35, this is not an essential configuration. For example, the wiring member 50 does not have to have a third extending portion 55. Also, the window portion 35 does not have to be a slit 34, but may be a hole that penetrates the carpet 30 or the like.
[0072] Furthermore, while it has been explained that the carpet 30 is divided into multiple sections and the silencer 20 has a size corresponding to the combined size of the multiple sections of the carpet 30, this is not a necessary configuration. For example, the silencer may be divided into multiple sections, and the carpet may have a size corresponding to the combined size of the multiple sections of the silencer.
[0073] Furthermore, the configurations described in each of the above embodiments and modifications can be combined as appropriate, as long as they do not contradict each other. [Explanation of symbols]
