Description
Exterior materials and wire harnesses
[0001] The present disclosure relates to an exterior member and a wire harness.
[0002] In conventional vehicles, when electrical devices are installed in the vehicle, electric wires connecting the electrical devices are sometimes arranged inside the passenger compartment of the vehicle (see, for example, Patent Document 1). In this case, it is common to arrange the electric wires in a position where they are not exposed, such as inside an interior component that constitutes the passenger compartment.
[0003] JP 2014-151778 A
[0004] As described above, when arranging the electric wires inside the interior part, the interior part must be attached and detached. This makes the work of arranging the electric wires complicated. Therefore, in order to easily arrange the electric wires inside the passenger compartment, it is conceivable to arrange the electric wires in an exposed state outside the interior part inside the passenger compartment. In this case, it is necessary to consider how to protect the electric wires.
[0005] An object of the present disclosure is to provide an exterior member and a wire harness that can protect electric wires arranged in a passenger compartment.
[0006] The exterior member of the present disclosure is an exterior member that protects electric wires arranged in the passenger compartment of a vehicle, and comprises a protective member having a sheet-like base member with an adhesive surface and a cover member fixed to the adhesive surface, the cover member comprising an upper wall portion, a pair of side wall portions extending from the upper wall portion and facing each other, and a storage recess formed by the inner surfaces of the upper wall portion and the pair of side wall portions, in which the electric wires are stored, and when the end of each of the pair of side wall portions that is connected to the upper wall portion is defined as a base end and the end opposite to the base end is defined as a tip end, the tip end of each of the pair of side wall portions is fixed in contact with the adhesive surface, and the opening of the storage recess formed between the tip ends of the pair of side wall portions is covered by the base member.
[0007] According to the exterior member and the wire harness of the present disclosure, it is possible to protect the electric wires arranged in the passenger compartment.

[0009] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be described. The exterior member of the present disclosure includes: [1] an exterior member for protecting electric wires arranged in a passenger compartment of a vehicle, the exterior member including a protective member having a sheet-like base member having an adhesive surface and a cover member fixed to the adhesive surface, the cover member including an upper wall portion, a pair of side wall portions extending from the upper wall portion and facing each other, and an accommodating recess formed by inner surfaces of the upper wall portion and the pair of side wall portions and accommodating the electric wires, when an end of each of the pair of side wall portions connected to the upper wall portion is defined as a base end and an end opposite to the base end is defined as a tip end, the tip end of each of the pair of side wall portions is fixed in contact with the adhesive surface, and an opening of the accommodating recess formed between the tip ends of the pair of side wall portions is covered by the base member.
[0010] According to this configuration, the electric wires arranged in the passenger compartment can be protected by the cover member. Also, according to the above configuration, the opening of the storage recess in the cover member is covered with the base member adhered to the tip end of each side wall portion, so that the electric wires can be prevented from falling out of the storage recess.
[0011] [2] In the above [1], the protective member may be one of a plurality of protective members provided on the exterior member, and the plurality of protective members may be arranged side by side in a direction perpendicular to the longitudinal direction of the electric wire.
[0012] According to this configuration, since a plurality of protective members are provided, additional wiring of electric wires is possible. Furthermore, for example, when removing one of the electric wires housed in the plurality of protective members, it is only necessary to remove the protective member housing the electric wire to be removed, which contributes to improving workability.
[0013] [3] In the above [2], the plurality of protective members may be arranged side by side so that the upper surfaces of the adjacent cover members are flush with each other. With this configuration, the upper surface of the exterior member formed by the upper surfaces of the juxtaposed cover members can be configured to be smooth, thereby contributing to improving the appearance.
[0014] [4] In any of the above [1] to [3], the side wall portion may have an extension portion extending from the tip portion to the opposite side of the accommodating recess, and the extension portion may be in contact with and fixed to the adhesive surface.
[0015]
[0013] In the above [4], when the adhesive surface is a first adhesive surface, the base member may have a second adhesive surface on the opposite side to the first adhesive surface.
[0016] According to this configuration, the protective member including the base member and the cover member can be easily attached to an attachment location inside the passenger compartment by the second adhesive surface of the base member. [6] In the above [5], the thickness of the extension portion in the thickness direction of the base member may be smaller than the thickness of the side wall portion in the thickness direction.
[0017] This configuration provides the following advantages. When attaching the protective member to an attachment location, the extending portion of the cover member is pressed against the attachment location, thereby adhering the second adhesive surface of the base member to the attachment location. At this time, the repulsive force of the extending portion may make it difficult to adhere the second adhesive surface to the attachment location. In this regard, with the above configuration, the thickness of the extending portion is smaller than the thickness of the side wall portion, so the repulsive force when the extending portion is pressed against the attachment location can be reduced. Therefore, it is easier to adhere the second adhesive surface to the attachment location when the extending portion is pressed, thereby improving the ease of installation of the exterior member.
[0018] [7] In any of the above [1] to [6], the cover member may be formed of a porous material. With this configuration, the electric wires can be suitably protected by the cover member formed of a porous material having a relatively high elasticity. Furthermore, by forming the cover member from a porous material, it is possible to suppress the generation of abnormal noise caused by collision between the electric wires and the cover member when the electric wires vibrate due to vehicle vibration or the like.
[0019] [8] A wire harness according to the present disclosure includes the exterior member according to any one of [1] to [7] above, and an electric wire housed in the protective member of the exterior member. This configuration can achieve the same effects as those of the above-described exterior member.
[0020] [Details of Embodiments of the Present Disclosure] Specific examples of the exterior member and wire harness of the present disclosure will be described below with reference to the drawings. In each drawing, for convenience of explanation, some components may be exaggerated or simplified. Furthermore, the dimensional ratios of each component may differ from one drawing to another. Furthermore, the terms "perpendicular" and "orthogonal" used herein do not necessarily refer to strictly perpendicular or orthogonal components, but also include roughly perpendicular or orthogonal components within the scope of the functions and effects of the present embodiment. Furthermore, the term "opposite" used herein refers to surfaces or components facing each other, and includes not only cases where the surfaces or components are completely facing each other, but also cases where the surfaces or components are partially facing each other. Furthermore, the term "opposite" used herein includes both cases where a component separate from the two components is interposed between the two components, and cases where there is no intervening component between the two components. Furthermore, the terms "first," "second," "third," and the like used herein are used simply to distinguish between objects and not to rank the objects. It should be noted that the present invention is not limited to these examples, but is defined by the scope of the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.
[0021] (Configuration of wire harness 10) As shown in Fig. 1 , the wire harness 10 of this embodiment includes an exterior member 11 and electric wires 12a, 12b housed in the exterior member 11. The wire harness 10 is disposed in a passenger compartment Va of a vehicle V. The exterior member 11 regulates the routing paths of the electric wires 12a, 12b disposed in the passenger compartment Va and protects the electric wires 12a, 12b. The exterior member 11 partially protects the electric wires 12a, 12b by covering a predetermined range in the longitudinal direction of the electric wires 12a, 12b.
[0022] The wire harness 10 includes, for example, two electric wires 12a and 12b. The electric wire 12a electrically connects a first electric device E1 and a second electric device E2, both of which are attached to the vehicle V. The electric wire 12b electrically connects, for example, a third electric device E3 and the second electric device E2, both of which are attached to the vehicle V. Examples of the first electric device E1 and the third electric device E3 include a sensor device such as an imaging device. The first electric device E1 and the third electric device E3 are provided in a position near the rear of the passenger compartment Va of the vehicle V, such as a back door of the vehicle V. Examples of the second electric device E2 include an electronic control unit (ECU). The second electric device E2 is provided, for example, inside or outside the passenger compartment Va, near the front of the passenger compartment Va. The passenger compartment Va is a room in the vehicle V where passengers including the driver ride. The exterior member 11 is fixed to a mounting location Vb (see FIG. 2) in the passenger compartment Va. Examples of the mounting location Vb include the ceiling surface and floor surface in the passenger compartment Va.
[0023] 2 and 3 , the exterior member 11 includes a first protective member 21 and a second protective member 22. Note that the drawings from Fig. 2 onwards show a first axis X, a second axis Y perpendicular to the first axis X, and a third axis Z perpendicular to the first axis X and the second axis Y. In this embodiment, the description will be given assuming that the direction along the first axis X is the length direction, the direction along the second axis Y is the width direction, and the direction along the third axis Z is the thickness direction.
[0024] The first protective member 21 and the second protective member 22 are arranged side by side in the width direction, which is a direction perpendicular to the length direction of the electric wires 12 a and 12 b. The first protective member 21 accommodates a portion of the electric wire 12 a in the length direction. The second protective member 22 accommodates a portion of the electric wire 12 b in the length direction.
[0025] (Configuration of First Protective Member 21) Fig. 4 shows a cross-sectional shape of the exterior member 11 perpendicular to the longitudinal direction. As shown in Fig. 4, the first protective member 21 includes a sheet-shaped first base member 30 and a first cover member 40 fixed to the first base member 30. The cross-sectional shape of the first protective member 21 including the first base member 30 and the first cover member 40 is, for example, uniform in the longitudinal direction. The first base member 30 is, for example, a double-sided tape. The first base member 30 has a first adhesive surface 31 and a second adhesive surface 32 opposite the first adhesive surface 31. The first cover member 40 is adhered to the first adhesive surface 31 of the first base member 30. The second adhesive surface 32 of the first base member 30 is adhered to the attachment location Vb.
[0026] The first cover member 40 is formed of, for example, an elastic resin material. Examples of the resin material forming the first cover member 40 include a porous material. Examples of the porous material forming the first cover member 40 include a foamed resin material formed of polyurethane, polyethylene, polystyrene, or the like.
[0027] The first cover member 40 includes an upper wall portion 41, a pair of side wall portions 42 extending from the upper wall portion 41 in the thickness direction, and an accommodating recess 43 in which the electric wire 12a is accommodated. The pair of side wall portions 42 face each other in the width direction of the first protective member 21. The accommodating recess 43 is formed by the inner surfaces of the upper wall portion 41 and the pair of side wall portions 42. Each side wall portion 42 has a base end portion 42a connected to the upper wall portion 41 and a tip end portion 42b that is the end opposite the base end portion 42a. The accommodating recess 43 is formed over the entire length of the first cover member 40. The accommodating recess 43 has an opening 44 formed between the tip ends 42b of the pair of side wall portions 42. The opening 44 opens in the thickness direction.
[0028] Each side wall 42 of the first cover member 40 includes an extension 45 extending outward in the width direction from a tip 42b. Each extension 45 extends from the tip 42b of each side wall 42 to the side opposite the storage recess 43. For example, each extension 45 is formed over the entire length of each side wall 42. The extensions 45 of each side wall 42 have the same shape. In the thickness direction, the thickness T1 of each extension 45 is set smaller than the thickness T2 of the side wall 42. Note that the thickness T2 of the side wall 42 is equal to the thickness of the first cover member 40. Note that in the first cover member 40 of this embodiment, for example, the upper surface from the upper wall 41 to the extension 45 has a curved shape.
[0029] The tip portions 42b and the extension portions 45 of each side wall portion 42 are in contact with and fixed to the first adhesive surface 31 of the first base member 30. This causes the first base member 30 to be attached to the first cover member 40. The opening 44 of the accommodating recess 43 is covered by the first base member 30. This prevents the electric wire 12a accommodated in the accommodating recess 43 from falling out of the opening 44. The electric wire 12a in the accommodating recess 43 may be adhered to the first adhesive surface 31 of the first base member 30, or the electric wire 12a may not be adhered to the first adhesive surface 31.
[0030] In the first cover member 40, as described above, each of the pair of extension portions 45 extends outward in the width direction from the tip end portion 42b of the corresponding side wall portion 42. Therefore, when viewed in the length direction (i.e., in a cross-sectional view along the width direction as shown in FIG. 4 ), the first cover member 40 has a symmetrical shape with respect to an axis passing through both the upper wall portion 41 and the accommodating recess 43. Note that the term "symmetrical shape" used in this disclosure means that each extension portion 45 extends from the tip end portion 42b of the corresponding side wall portion 42, and does not intend that the shapes are completely symmetrical.
[0031] (Configuration of second protective member 22) The second protective member 22 includes a sheet-shaped second base member 50 and a second cover member 60 fixed to the second base member 50. The cross-sectional shape of the second protective member 22 including the second base member 50 and the second cover member 60 is uniform, for example, in the length direction.
[0032] The second base member 50 is, for example, a double-sided tape. The second base member 50 has a first adhesive surface 51 and a second adhesive surface 52 opposite the first adhesive surface 51. The second cover member 60 is adhered to the first adhesive surface 51 of the second base member 50. The second adhesive surface 52 of the second base member 50 is adhered to the attachment location Vb.
[0033] The second cover member 60 is formed of, for example, an elastic resin material. Examples of the resin material forming the second cover member 60 include a porous material. Examples of the porous material forming the second cover member 60 include a foamed resin material formed of polyurethane, polyethylene, polystyrene, or the like.
[0034] The second cover member 60 includes an upper wall portion 61, a pair of side wall portions 62 extending from the upper wall portion 61 in the thickness direction, and an accommodating recess 63 in which the electric wire 12b is accommodated. The pair of side wall portions 62 face each other in the width direction of the second protective member 22. The accommodating recess 63 is formed by the inner surfaces of the upper wall portion 61 and the pair of side wall portions 62. Each side wall portion 62 has a base end portion 62a connected to the upper wall portion 61 and a tip end portion 62b that is the end opposite the base end portion 62a. The accommodating recess 63 is formed over the entire length of the second cover member 60. The accommodating recess 63 has an opening 64 formed between the tip ends 62b of the pair of side wall portions 62. The opening 64 opens in the thickness direction.
[0035] In the second cover member 60, one of the pair of side wall portions 62 has an extension portion 65 extending outward in the width direction from a tip portion 62b. The extension portion 65 extends from the tip portion 62b of the side wall portion 62 to the side opposite the accommodating recess 63. The extension portion 65 is formed, for example, over the entire length of the side wall portion 62. The extension portion 65 of the second cover member 60 has the same shape as the extension portion 45 of the first cover member 40.
[0036] The tip portion 62b of each side wall portion 62 and the extension portion 65 of one side wall portion 62 are in contact with and fixed to the first adhesive surface 51 of the second base member 50. This causes the second base member 50 to be attached to the second cover member 60. The opening 64 of the accommodating recess 63 is covered by the second base member 50. This prevents the electric wire 12b accommodated in the accommodating recess 63 from falling out of the opening 64. The electric wire 12b in the accommodating recess 63 may be adhered to the first adhesive surface 51 of the second base member 50, or the electric wire 12b may not be adhered to the first adhesive surface 51.
[0037] Of the pair of side wall portions 62 of the second cover member 60, the side wall portion 62 that does not have the extension portion 65 has an overlapping portion 66 that extends outward in the width direction from the side wall portion 62. The overlapping portion 66 extends from the side wall portion 62 to the side opposite the accommodating recess 63. The upper surface of the overlapping portion 66 and the upper wall portion 61 are flush with each other.
[0038] In the second cover member 60, as described above, the extension portion 65 extends outward in the width direction from the tip end portion 62b of the corresponding side wall portion 62. Meanwhile, the overlapping portion 66 extends outward in the width direction from the base end portion 62a of the corresponding side wall portion 62. Therefore, in contrast to the first cover member 40 having a symmetrical shape described above, the second cover member 60 has an asymmetrical shape with respect to an axis passing through both the upper wall portion 61 and the accommodating recess 63 when viewed in its length direction (i.e., in a cross-sectional view along the width direction as shown in FIG. 4 ). By making the second cover member 60 asymmetrical, the second cover member 60 can be disposed so as to partially overlap the first cover member 40 having a symmetrical shape in the width direction. This allows for space-saving arrangement of the electric wires 12a and 12b while improving the appearance of the exterior member 11.
[0039] When the first protective member 21 and the second protective member 22 are arranged side by side in the width direction, the overlapping portion 66 of the second cover member 60 is located above one of the pair of extending portions 45 of the first cover member 40 in the thickness direction. That is, the extending portion 45 and the overlapping portion 66 overlap in the thickness direction. The upper surface of the overlapping portion 66 and the upper surface of the upper wall portion 41 of the first cover member 40 are flush with each other. The lower surface of the overlapping portion 66 that faces the first cover member 40 in the thickness direction has a curved shape that follows the curved shape of the upper surface of the first cover member 40.
[0040] In the thickness direction, the thickness of the first cover member 40 and the thickness of the second cover member 60 are set to be equal to each other. Specifically, the thickness of the side wall portion 62 of the second cover member 60 is equal to the thickness T2 of the side wall portion 42 of the first cover member 40. Furthermore, the thickness of the extension portion 65 of the second cover member 60 is equal to the thickness T1 of the extension portion 45 of the first cover member 40. That is, the thickness of the extension portion 65 of the second cover member 60 is set to be smaller than the thickness of the side wall portion 62.
[0041] (Operation of the Present Embodiment) The operation of the present embodiment will be described below. When the first electrical device E1 is attached to the vehicle V, the first protective member 21 of the exterior member 11 is used to arrange the electric wires 12a extending from the first electrical device E1 inside the passenger compartment Va.
[0042] When attaching the electric wire 12a to the first protective member 21, for example, the electric wire 12a is accommodated in the accommodation recess 43 of the first cover member 40, and then the first base member 30 is attached to the underside of the first cover member 40, i.e., to the undersides of the tip portions 42b and extension portions 45 of each side wall portion 42. Note that, as another attachment method, it is also possible to place the electric wire 12a on the first adhesive surface 31 of the first base member 30 and adhere it thereto, and then attach the first cover member 40 to the first adhesive surface 31.
[0043] After the electric wires 12a are attached to the first protective member 21, the first protective member 21 is attached to the attachment location Vb. Here, the first protective member 21 is attached to the attachment location Vb by the second adhesive surface 32 of the first base member 30. At this time, the extension portions 45 of each side wall portion 42 are pressed against the attachment location Vb, thereby adhering the second adhesive surface 32 to the attachment location Vb.
[0044] The first protective member 21 attached to the attachment location Vb as described above restricts the routing path of the electric wire 12a within the passenger compartment Va. This makes it possible to suppress interference with the electric wire 12a, such as an occupant or a peripheral component getting caught on the electric wire 12a. Furthermore, the first cover member 40 of the first protective member 21 is formed of a porous material having a relatively high elasticity. Therefore, the first cover member 40 can suitably protect the electric wire 12a and also suppress the generation of abnormal noise caused by collision between the electric wire 12a and the first cover member 40 when the electric wire 12a vibrates due to vehicle vibration or the like.
[0045] Next, when a third electric device E3 including the electric wire 12b is added to the vehicle V, the second protective member 22 of the exterior member 11 is used to arrange the electric wire 12b in the passenger compartment Va. The method of attaching the electric wire 12b to the second protective member 22 is similar to the method of attaching the electric wire 12a to the first protective member 21, and therefore detailed description thereof will be omitted.
[0046] After the electric wire 12b is attached to the second protective member 22, the second protective member 22 is attached to the attachment location Vb so as to be aligned in the width direction with the first protective member 21 fixed to the attachment location Vb. At this time, the second protective member 22 is positioned so that the overlapping portion 66 of the second cover member 60 overlaps one of the extension portions 45 of the first cover member 40. Then, by pressing the extension portion 65 of the second cover member 60 against the attachment location Vb, the second adhesive surface 52 of the second base member 50 is adhered to the attachment location Vb.
[0047] The second protective member 22 attached to the attachment location Vb as described above restricts the routing path of the added electric wire 12b. This makes it possible to suppress interference with the electric wire 12b, such as an occupant or a peripheral component getting caught on the electric wire 12b. Furthermore, the second cover member 60 of the second protective member 22 is formed of a porous material having a relatively high elasticity. Therefore, the second cover member 60 can suitably protect the electric wire 12b and also suppress the generation of abnormal noise caused by collision between the electric wire 12b and the second cover member 60 when the electric wire 12b vibrates due to vehicle vibration or the like.
[0048] As shown in FIG. 5 , when an electric wire 12c is to be added in addition to the electric wires 12a and 12b, another second protective member 22 is used. Here, the second protective member 22 already attached to the attachment location Vb is referred to as the second protective member 22a, and the additional second protective member 22 is referred to as the second protective member 22b. After the electric wire 12c is attached to the second protective member 22b, the second protective member 22b is attached to the attachment location Vb so as to be aligned in the width direction with the second protective member 22a fixed to the attachment location Vb. At this time, the second protective member 22b is positioned so that the overlapping portion 66 of the second protective member 22b overlaps the extending portion 65 of the second protective member 22a. Note that when an electric wire is to be added in addition to the electric wires 12a, 12b, and 12c, the additional electric wire can be attached to the passenger compartment Va using the second protective member 22, as described above.
[0049] (Advantages of the Present Embodiment) The advantages of the present embodiment are described below. (1) The electric wire 12a arranged in the passenger compartment Va can be protected by the first cover member 40 made of, for example, a porous material. Similarly, the electric wires 12b, 12c arranged in the passenger compartment Va can be protected by the second cover member 60 made of, for example, a porous material. Furthermore, according to the configuration of the present embodiment, the opening 44 of the accommodating recess 43 in the first cover member 40 is covered by the first base member 30 bonded to the tip end portions 42b of each side wall portion 42, thereby preventing the electric wire 12a from falling out of the accommodating recess 43. Similarly, the opening 64 of the accommodating recess 63 in the second cover member 60 is covered by the second base member 50 bonded to the tip end portions 62b of each side wall portion 62, thereby preventing the electric wires 12b, 12c from falling out of the accommodating recess 63.
[0050] (2) The exterior member 11 includes a plurality of protective members (first protective member 21 and second protective member 22). The first protective member 21 and the second protective member 22 are arranged side by side in a direction perpendicular to the longitudinal direction of the electric wires 12a and 12b. This configuration allows additional electric wires to be wired by using a plurality of protective members (first protective member 21 and second protective member 22). Furthermore, for example, when removing the electric wire 12b, only the second protective member 22 needs to be removed from the exterior member 11, which contributes to improved workability.
[0051] (3) The first protective member 21 and the second protective member 22 are arranged side by side so that the upper surfaces of the first cover member 40 and the second cover member 60 adjacent to each other in the width direction are flush with each other. With this configuration, the upper surface of the exterior member 11 formed by the upper surfaces of the first cover member 40 and the second cover member 60 arranged side by side can be configured to be smooth, which contributes to improving the appearance.
[0052] (4) In the first cover member 40, the side wall portion 42 includes an extension portion 45 extending from the tip portion 42b toward the opposite side from the accommodating recess 43. The extension portion 45 is fixed in contact with the first adhesive surface 31 of the first base member 30. This configuration makes it possible to increase the adhesion area of the first cover member 40 to the first adhesive surface 31. This makes it possible to improve the fixing strength between the first base member 30 and the first cover member 40. In addition, in the second cover member 60, one side wall portion 62 includes an extension portion 65 extending from the tip portion 62b toward the opposite side from the accommodating recess 63. The extension portion 65 is fixed in contact with the first adhesive surface 51 of the second base member 50. This configuration makes it possible to increase the adhesion area of the second cover member 60 to the first adhesive surface 51. This makes it possible to improve the fixing strength between the second base member 50 and the second cover member 60.
[0053] (5) In the first protective member 21, the first base member 30 has a second adhesive surface 32 on the side opposite the first adhesive surface 31. According to this configuration, the second adhesive surface 32 of the first base member 30 makes it possible to easily attach the first protective member 21, including the first base member 30 and the first cover member 40, to an attachment location Vb within the passenger compartment Va. Furthermore, in the second protective member 22, the second base member 50 has a second adhesive surface 52 on the side opposite the first adhesive surface 51. According to this configuration, the second adhesive surface 52 of the second base member 50 makes it possible to easily attach the second protective member 22, including the second base member 50 and the second cover member 60, to an attachment location Vb within the passenger compartment Va.
[0054] (6) In the first protective member 21, the thickness T1 of the extension portion 45 is smaller than the thickness T2 of the side wall portion 42. When attaching the first protective member 21 to the attachment location Vb, the extension portion 45 of the first cover member 40 is pressed against the attachment location Vb to adhere the second adhesive surface 32 of the first base member 30 to the attachment location Vb. At this time, the repulsive force of the porous material forming the extension portion 45 may make it difficult to adhere the second adhesive surface 32 to the attachment location Vb. In this regard, with the above configuration, the thickness T1 of the extension portion 45 is smaller than the thickness T2 of the side wall portion 42, thereby reducing the repulsive force when the extension portion 45 is pressed against the attachment location Vb. This makes it easier to adhere the second adhesive surface 32 to the attachment location Vb when the extension portion 45 is pressed against the attachment location Vb, thereby improving the ease of installation of the exterior member 11. The second protective member 22 also has a similar configuration, achieving the same effect as described above.
[0055] (7) The first cover member 40 is formed of a porous material. With this configuration, the first cover member 40, which is formed of a porous material having a relatively high elasticity, can suitably protect the electric wires 12a. Furthermore, by forming the first cover member 40 of a porous material, it is possible to suppress the generation of abnormal noise caused by a collision between the electric wires 12a and the first cover member 40 when the electric wires 12a vibrate due to vehicle vibration or the like. Furthermore, in this embodiment, the second cover member 60 is also formed of a porous material, and the same effect as above can be obtained.
[0056] (Other Embodiments) The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other within the scope of technical compatibility.
[0057] The configuration of the first cover member 40 and the second cover member 60, such as their shapes, is not limited to the above embodiment and can be modified as appropriate. For example, in the configuration shown in Fig. 6, the exterior member 11 includes the first protective member 21 and the second protective member 22, each of which includes a cover member 70 having the same shape and a sheet-like base member 80 attached to the cover member 70.
[0058] Like the first cover member 40 and the second cover member 60 of the above embodiment, the cover member 70 is formed of a resin material such as a porous material. The cover member 70 includes an upper wall portion 71, a pair of side wall portions 72 extending from the upper wall portion 71 in the thickness direction, and an accommodating recess 73. The pair of side wall portions 72 face each other in the width direction. The accommodating recess 73 is formed by the inner surfaces of the upper wall portion 71 and the pair of side wall portions 72. Each side wall portion 72 has a base end portion 72a connected to the upper wall portion 71 and a tip end portion 72b opposite the base end portion 72a. The accommodating recess 73 is formed over the entire length of the cover member 70. The accommodating recess 73 has an opening 74 formed between the tip ends 72b of the pair of side wall portions 72. The opening 74 opens in the thickness direction.
[0059] In the cover member 70, one of the pair of side wall portions 72 has an extension portion 75 extending outward in the width direction from a tip portion 72b. The extension portion 75 extends from the tip portion 72b of each side wall portion 72 to the side opposite the accommodating recess 73. The extension portion 75 is formed, for example, over the entire length of each side wall portion 72. Note that the extension portion 75 of the cover member 70 has the same shape as, for example, the extension portions 45, 65 of the exterior member 11 of the above embodiment. Of the pair of side wall portions 72 in the cover member 70, the outer surface in the width direction of the side wall portion 72 that does not have the extension portion 75 has, for example, a flat surface perpendicular to the width direction.
[0060] The base member 80 is, for example, double-sided tape. The base member 80 has a first adhesive surface 81 and a second adhesive surface 82 opposite the first adhesive surface 81. The cover member 70 is adhered to the first adhesive surface 81 of the base member 80. The second adhesive surface 82 of the base member 80 is adhered to the attachment location Vb. The tip portions 72b of each side wall portion 72 of the cover member 70 and the extension portion 75 of one side wall portion 72 are in contact with and fixed to the first adhesive surface 81 of the base member 80. This causes the base member 80 to be attached to the cover member 70. The opening 74 of the accommodating recess 73 is covered by the base member 80. This prevents the electric wires 12a, 12b accommodated in the accommodating recess 73 from falling out of the opening 74.
[0061] 6, the first protective member 21 and the second protective member 22 are arranged side by side in the width direction so that the side wall portions 72 that do not have the extension portions 75 are adjacent to each other. Even with the configuration shown in FIG. 6, it is possible to obtain substantially the same effects as in the above embodiment.
[0062] The exterior member 11 of the above embodiment may be changed to, for example, an exterior member 11A as shown in Fig. 7. The exterior member 11A includes a protective member 100 having a sheet-shaped base member 101 and a cover member 102 fixed to the base member 101.
[0063] The base member 101 is, for example, a double-sided tape. The base member 101 has a first adhesive surface 111 and a second adhesive surface 112 opposite the first adhesive surface 111. The cover member 102 is adhered to the first adhesive surface 111 of the base member 101. The second adhesive surface 112 of the base member 101 is adhered to the attachment location Vb.
[0064] The cover member 102 is formed of a resin material such as a porous material, similar to the first cover member 40 and the second cover member 60 of the above embodiment. The cover member 102 includes an upper wall portion 121, a pair of side wall portions 122 extending from the upper wall portion 121 in the thickness direction, and a partition portion 123 extending between the pair of side wall portions 122 in the thickness direction. The cover member 102 also includes a plurality of accommodating recesses 124 that accommodate the electric wires 12. Each accommodating recess 124 is formed by the upper wall portion 121, the side wall portion 122, and the partition portion 123. That is, the accommodating recess 124 is located between the side wall portion 122 and the partition portion 123 in the width direction. The cover member 102 also includes, for example, two accommodating recesses 124. Each accommodating recess 124 is formed over the entire length of the cover member 102. Each accommodating recess 124 has an opening 125 that opens in the thickness direction. Each side wall portion 122 of the cover member 102 has an extension portion 126 similar to the extension portion 45 of the first cover member 40 of the above embodiment.
[0065] The pair of side wall portions 122 and the respective tip portions and extension portion 126 of the partition portion 123 are in contact with and fixed to the first adhesive surface 111 of the base member 101. As a result, the base member 101 is attached to the cover member 102. The openings 125 of each accommodating recess 124 are covered by the base member 101. As a result, the electric wires 12 accommodated in each accommodating recess 124 are prevented from falling out of the openings 125.
[0066] The configuration shown in Fig. 7 can also achieve substantially the same effects as the above embodiment. The number of accommodating recesses 124 in the cover member 102 is not limited to the configuration shown in Fig. 7 and may be three or more. When adding an electric wire 12 to the configuration shown in Fig. 7, the second protective member 22 in the above embodiment may be used.
[0067] In the first cover member 40 of the above embodiment, the upper surface extending from the upper wall portion 41 to the extension portion 45 has a curved shape, but this is not particularly limited, and the shape of the upper surface can be changed as appropriate. For example, the upper surface may be a flat surface that slopes so that the thickness of the first cover member 40 decreases toward both ends of the first cover member 40 in the width direction. Furthermore, it is desirable to change the shape of the lower surface of the overlapping portion 66 of the second cover member 60 in accordance with the change in the shape of the upper surface.
[0068] In the exterior member 11 of the above embodiment, the number of electric wires 12a, 12b accommodated in each of the accommodation recesses 43, 63 is not limited to one, and may be two or more. The embodiments disclosed herein are exemplary in all respects, and the present invention is not limited to these examples. That is, the scope of the present invention is defined by the claims, and it is intended to include all modifications within the meaning and scope of the claims.
