According to this configuration, since the outer periphery of the electromagnetic wave absorbing member is covered by the porous cushioning member, the cushioning member can be interposed between the electromagnetic wave absorbing member and its peripheral parts. As a result, it is possible to suppress the direct contact between the electromagnetic wave absorbing member and the peripheral parts, so that it is possible to suppress the generation of abnormal noise due to the contact between the electromagnetic wave absorbing member and the peripheral parts. Further, since the cushioning member is fixed so as to bridge the outer periphery of the first exterior member and the outer periphery of the second exterior member, the cushioning member is not fixed to the electric wire member itself, but is between the cushioning member and the electric wire member. Space can be provided. As a result, the movement of the electric wire member can be allowed in the internal space of the cushioning member, and the arrangement of the electric wire member can be improved.

[2] The cushioning member is formed in a sheet shape having slits extending along the length direction of the electric wire member, and the cushioning member is a first direction intersecting the length direction of the electric wire member.

It is preferable that the through hole is penetrated in a state where the outer circumference of the cable is covered. According to this configuration, the electric wire is penetrated through the through hole of the electromagnetic wave absorbing member in a state of being covered with the covering member. Therefore, it is possible to prevent the inner peripheral surface of the through hole from directly contacting the outer peripheral surface of the electric wire. As a result, damage to the electric wire due to contact with the inner peripheral surface of the through hole can be suitably suppressed.

[5] One end of the covering member in the length direction is housed in the internal space of the first exterior member, and the other end of the covering member in the length direction is housed in the internal space of the second exterior member. It is preferable that it is. According to this configuration, the entire length of the electric wire exposed from both the first exterior member and the second exterior member can be protected by the covering member.

Therefore, the covering member can be easily attached to the electric wire later. Thereby, the assembly workability of the wire harness can be improved.

In addition, the electromagnetic wave absorbing member can be fixed to the electric wire by the fixing member. As a result, it is possible to preferably prevent the electromagnetic wave absorbing member from being displaced with respect to the electric wire. Further, by forming the fixing member so as to cover the outer periphery of the covering member over the entire circumference in the circumferential direction, the tubular state of the covering member can be maintained by the fixing member. As a result, it is possible to suppress an increase in the number of parts as compared with the case where the member for fixing the electromagnetic wave absorbing member to the electric wire and the member for maintaining the tubular state of the covering member are separately provided.

Is made). Therefore, even when the electromagnetic wave absorbing member vibrates due to the traveling of the vehicle or the like, it is possible to prevent the electric wire member from being shaken in the through hole due to the vibration of the electromagnetic wave absorbing member. For example, compared to the case where the electromagnetic wave absorbing portion and the electric wire member are fixed in a state where the electric wire member does not contact the inner peripheral surface of the through hole of the electromagnetic wave absorbing member, the electric wire member is inside the through hole due to the vibration of the electromagnetic wave absorbing member. It is possible to suppress the movement with. As a result, it is possible to suppress wear of the electric wire member due to contact with the inner peripheral surface of the through hole, and it is possible to preferably suppress damage to the electric wire member due to vibration of the electromagnetic wave absorbing member.

Here, "opposing" in the present specification means that the faces or members are in front of each other, not only when they are completely in front of each other, but also when they are partially in front of each other. Including the case of being in position. Further, the term "opposing" in the present specification refers to both the case where a member other than the two parts is interposed between the two parts and the case where nothing is interposed between the two parts. including.

A second region formed so as to extend to the electric wire member led out to the above, and a third region in which the tape member is wound around the outer periphery of the electric wire member led out from the through hole to the first exterior member side. And a fourth region formed so that the tape member pulled out from the third region is adhered to the outer peripheral surface of the electromagnetic wave absorbing member and extends to the first region. The tape member in the fourth region is formed so as to extend so as to intersect with the tape member in the second region, and the tape member is a part of the outer peripheral surface of the electromagnetic wave absorbing member in the circumferential direction. The first portion is formed so as to cover only, and the first portion absorbs the electromagnetic wave covered by the tape member more than the second portion in a direction intersecting the central axis direction in which the central axis of the through hole extends. It is preferable that the portion is arranged at a position close to the outer peripheral surface of the member.

According to this configuration, the tape member is formed so as to cover only a part of the outer peripheral surface of the electromagnetic wave absorbing member in the circumferential direction. Thereby, for example, the length of the tape member can be shortened as compared with the case where the tape member is formed so as to cover the outer peripheral surface of the electromagnetic wave absorbing member over the entire circumference in the circumferential direction. As a result, the manufacturing cost of the wire harness can be reduced.

The grommet 50 has, for example, a tubular shape that collectively surrounds the outer circumferences of the plurality of electric wires 20 as a whole. The grommet 50 is formed in a cylindrical shape as a whole, for example. The grommet 50 is attached to, for example, a mounting hole 200X formed in the vehicle body panel 200. Here, the vehicle body panel 200 is located between, for example, a waterproof area that needs to be waterproof (for example, outside the vehicle interior) and a non-waterproof area that does not need to be waterproof (for example, inside the vehicle interior). That is, the vehicle body panel 200 is provided so as to partition the outside of the vehicle interior, which is a waterproof region, and the interior of the vehicle, which is a non-waterproof region. The mounting hole 200X is formed so as to penetrate the vehicle body panel 200 in the thickness direction, and is formed so that a plurality of electric wires 20 can be inserted.

As the material of the grommet 50, for example, an elastic material having a relatively high hardness can be used. As the elastic material, for example, rubber such as ethylene propylene diene rubber or elastomer can be used. The grommet 50 has a function of waterproofing in the mounting hole 200X so that water does not enter the vehicle interior side of the non-waterproof area from the outside of the vehicle interior which is a waterproof area, and a function of fixing a plurality of electric wires 20 to the mounting hole 200X. Have.

The grommet 50 was connected to, for example, a tubular portion 51, a flange portion 52 connected to an end portion of the tubular portion 51, and an end portion of the flange portion 52 opposite to the end portion connected to the tubular portion 51. It has a tubular portion 53. The flange portion 52 is formed so as to project radially outward from the other portions, that is, the outer circumferences of the

tubular portions

51 and 53. The flange portion 52 is formed so as to project radially outward from the

tubular portions

51 and 53 over the entire circumference of the

tubular portions

51 and 53 in the circumferential direction, for example. That is, the outer diameter of the flange portion 52 is formed to be larger than the outer diameter of the

tubular portions

51 and 53. The grommet 50 is, for example, a single component in which the tubular portion 51, the flange portion 52, and the tubular portion 53 are continuously and integrally formed.

When the grommet 50 is attached to the mounting hole 200X of the vehicle body panel 200, the flange portion 52 is fitted into the mounting hole 200X, the tubular portion 51 is arranged outside the vehicle interior, and the tubular portion 53 is arranged inside the vehicle interior. The tubular portion 51 is fitted to the outer circumference of the corrugated tube 40. The tubular portion 51 is formed in a tubular shape having a size that can be fitted to the outer circumference of the corrugated tube 40, for example. The tubular portion 51 of the present embodiment is formed in a cylindrical shape. On the inner peripheral surface of the end of the tubular portion 51, for example, one or a plurality (here, four) lips 51A that are engaged with the corrugated tube 40 are formed. Each lip 51A is formed continuously over the entire circumference of the inner peripheral surface of the tubular portion 51, for example, and is formed in a closed ring shape. Each lip 51A is formed so as to enter the annular recess 42 of the corrugated tube 40, for example, when the tubular portion 51 is fitted to the outer circumference of the corrugated tube 40.

For example, a connecting member 55 is provided on the outer peripheral surface of the tubular portion 51. As the connecting member 55, for example, a binding band made of resin or metal, a caulking ring, or the like can be used. The outer peripheral side of the tubular portion 51 is tightened by the connecting member 55 and fixed to the corrugated tube 40. Specifically, the tubular portion 51 is tightened from the outer peripheral side by the connecting member 55 until it adheres to the corrugated tube 40 in a liquidtight manner. As a result, it is possible to prevent water from entering the inside of the grommet 50 from between the tubular portion 51 and the corrugated tube 40.

Here, the corrugated tube 40 is provided so as to penetrate the grommet 50, for example. The corrugated tube 40 is formed so as to extend from the outside of the vehicle interior, which is a waterproof region, to the interior of the vehicle, which is a non-waterproof region, through the internal space of the grommet 50, for example. The corrugated tube 40 is derived from both ends of the grommet 50 in the axial direction.

The flange portion 52 is configured to elastically adhere to the vehicle body panel 200, for example, when the grommet 50 is attached to the mounting hole 200X. The flange portion 52 has, for example, a ring plate shape that is consistent with the mounting hole 200X as a whole. The flange portion 52 has an outer flange 52A connected to the tubular portion 51 and an inner flange 52B connected to the tubular portion 53. When the grommet 50 is attached to the mounting hole 200X, the outer flange 52A is arranged outside the vehicle interior and the inner flange 52B is arranged inside the vehicle interior.

A groove 54 is provided between the outer flange 52A and the inner flange 52B into which the vehicle body panel 200 constituting the peripheral edge of the mounting hole 200X is fitted. When the vehicle body panel 200 is fitted in the groove 54, the outer flange 52A is in close contact with the surface of the vehicle body panel 200 facing the outside of the vehicle interior, and the inner flange 52B is in close contact with the surface of the vehicle body panel 200 facing the interior of the vehicle interior. As a result, the vehicle body panel 200 is elastically sandwiched between the outer flange 52A and the inner flange 52B. Therefore, when the vehicle body panel 200 is fitted into the groove portion 54, the movement of the grommet 50 in the axial direction is restricted.

The tubular portion 53 is connected to, for example, the inner flange 52B. The tubular portion 53 is formed in a tubular shape having a size that allows the corrugated tube 40 to be inserted, for example. The tubular portion 53 of the present embodiment is formed in a cylindrical shape.

The end of the corrugated tube 40 is derived from, for example, the tubular portion 53 of the grommet 50. For example, the corrugated tube 40 led out from the tubular portion 53 is fixed to the tubular portion 53 by a tape (not shown) wound around the outer circumference of the tubular portion 53 and the outer circumference of the corrugated tube 40.

The plurality of electric wires 20 are formed so as to extend from the outside of the vehicle interior, which is a waterproof region, to the interior of the vehicle, which is a non-waterproof region, through, for example, the internal space of the grommet 50 and the internal space of the corrugated tube 40. The plurality of electric wires 20 are led out from the end portion of the corrugated tube 40, for example, in the vehicle interior. The electric wire 20 led out from the corrugated tube 40 is formed so as to extend toward the connector C1 in the vehicle interior, for example.

The corrugated tube 60 has, for example, a tubular shape that collectively surrounds the outer circumferences of the plurality of electric wires 20 as a whole. The corrugated tube 60 has a bellows structure in which annular convex portions 61 and annular concave portions 62 are alternately arranged along the length direction thereof. The corrugated tube 60 is more flexible than the core wire 21. The corrugated tube 60 of the present embodiment is formed in a cylindrical shape. As the material of the corrugated tube 60 of the present embodiment, a resin material having no conductivity is used. As the resin material, for example, synthetic resins such as polyolefin, polyamide, polyester, and ABS resin can be used.

(1) The wire harness 10 has an electric wire 20, a corrugated tube 40 accommodating the electric wire 20, and a corrugated tube 60 accommodating the electric wire 20 and provided apart from the corrugated tube 40 in the length direction of the electric wire 20. .. The wire harness 10 has a through hole 81 through which the electric wire 20 penetrates, and the electromagnetic wave absorbing member 80 provided between the corrugated tube 40 and the corrugated tube 60 in the length direction of the electric wire 20 and the outer circumference of the electromagnetic wave absorbing member 80. It has a porous buffer member 110 that covers the above. The cushioning member 110 is fixed so as to bridge the outer circumference of the corrugated tube 40 and the outer circumference of the corrugated tube 60.

According to this configuration, since the electromagnetic wave absorbing member 80 is covered with the porous cushioning member 110, the cushioning member 110 can be interposed between the electromagnetic wave absorbing member 80 and its peripheral parts. As a result, it is possible to suppress the generation of abnormal noise caused by the contact between the electromagnetic wave absorbing member 80 and the peripheral parts.

(2) Further, since the cushioning member 110 is fixed so as to bridge the outer circumference of the corrugated tube 40 and the outer circumference of the corrugated tube 60, the cushioning member 110 is not fixed to the electric wire 20 itself, and the cushioning member 110 and the electric wire 20 are not fixed. A space can be provided between and. As a result, the movement of the electric wire 20 can be allowed in the internal space of the cushioning member 110, and the arrangement of the electric wire 20 can be improved.

(3) By superimposing the end portion 113 on the end portion 112 of the sheet-shaped cushioning member 110, the cushioning member 110 is formed so as to form a tubular shape that surrounds the outer circumference of the electromagnetic wave absorbing member 80 over the entire circumference in the circumferential direction. .. Therefore, the cushioning member 110 can be easily attached to the wire harness 10 later. Thereby, the assembly workability of the wire harness 10 can be improved.

(4) Further, the outer circumference of the electromagnetic wave absorbing member 80 is surrounded by the cushioning member 110 formed so as to form a tubular shape over the entire circumference in the circumferential direction. As a result, it is possible to suppress the generation of abnormal noise caused by the contact between the electromagnetic wave absorbing member 80 and the peripheral parts over the entire circumference of the electromagnetic wave absorbing member 80 in the circumferential direction.

(5) Further, by adjusting the overlapping width between the end portion 112 and the end portion 113, the inner peripheral dimension and the outer peripheral dimension of the cushioning member 110 can be easily adjusted according to the outer peripheral dimension of the electromagnetic wave absorbing member 80. .. As a result, it is possible to preferably suppress an increase in the outer peripheral dimension of the cushioning member 110.

(6) A covering member 70 is provided between the corrugated tube 40 and the corrugated tube 60 to cover the outer circumference of the electric wire 20, and the electric wire 20 is provided with a through hole of the electromagnetic wave absorbing member 80 in a state of being covered by the covering member 70. It was made to penetrate 81. Therefore, it is possible to prevent the inner peripheral surface of the through hole 81 from directly contacting the outer peripheral surface of the electric wire 20. As a result, damage to the electric wire 20 due to contact with the inner peripheral surface of the through hole 81 can be suitably suppressed.

(7) The electromagnetic wave absorbing member 80 is fixed to the electric wire 20 by the fixing member 90. As a result, it is possible to preferably prevent the electromagnetic wave absorbing member 80 from being displaced with respect to the electric wire 20.

(8) By superimposing the end portion 73 on the end portion 72 of the sheet-shaped covering member 70, the covering member 70 is formed so as to form a tubular shape that surrounds the outer circumference of the electric wire 20 over the entire circumference in the circumferential direction. Therefore, the covering member 70 can be easily attached to the electric wire 20 later. Thereby, the assembly workability of the wire harness 10 can be improved.

(9) By forming the fixing member 90 so as to cover the entire circumference of the outer circumference of the covering member 70 in the circumferential direction, the tubular state of the covering member 70 can be maintained by the fixing member 90. As a result, it is possible to suppress an increase in the number of parts as compared with the case where the member for fixing the electromagnetic wave absorbing member 80 to the electric wire 20 and the member for maintaining the tubular state of the covering member 70 are separately provided.

(10) The tape member 91 is formed so as to cover only a part of the outer peripheral surface of the electromagnetic wave absorbing member 80 in the circumferential direction. Thereby, for example, the length of the tape member 91 can be shortened as compared with the case where the tape member is formed so as to cover the outer peripheral surface of the electromagnetic wave absorbing member 80 over the entire circumference in the circumferential direction. As a result, the manufacturing cost of the wire harness 10 can be reduced.

(11) The braided member 100 was formed so as to surround the outer periphery of the electromagnetic wave absorbing member 80, and the cushioning member 110 was formed so as to cover the outer periphery of the braided member 100. As a result, since the cushioning member 110 can be interposed between the braided member 100 and the peripheral parts, it is possible to preferably prevent the braided member 100 from being disconnected due to contact between the braided member 100 and the peripheral parts, for example. ..

(12) The end of the corrugated tube 40, the electromagnetic wave absorbing member 80, the corrugated tube 60, and the cushioning member 110 are provided between the tubular portion 53 arranged in the non-waterproof region of the grommet 50 and the connector C1. .. According to this configuration, the electromagnetic wave absorbing member 80 is arranged in the non-waterproof region. Therefore, it is not necessary to make the electromagnetic wave absorbing member 80 and its peripheral region a waterproof structure. As a result, it is not necessary to provide an additional member for the waterproof structure, so that an increase in the number of parts can be suppressed.

(Other embodiments)
The above embodiment can be modified and implemented as follows. The above embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.

-In the above embodiment, the tape member 91 is wound so as to expose the end portion of the covering member 70 in the length direction, but the present invention is not limited to this.

For example, as shown in FIG. 10, the tape member 91 may be wound so as to cover the end portion of the covering member 70 in the length direction. In this case, the tape member 91 is wound, for example, over the outer peripheral surface of the end portion of the covering member 70 in the length direction and the outer peripheral surface of the electric wire 20 exposed from the covering member 70. For example, the tape member 91 is continuously wound around the range from the outer peripheral surface of the covering member 70 to the outer peripheral surface of the electric wire 20. According to such a configuration, it is possible to more preferably suppress the covering member 70 from returning to the sheet state.

For example, as shown in FIG. 11, the electric wire member 25 may be arranged in contact with a part of the inner peripheral surface of the through hole 81 inside the through hole 81 of the electromagnetic wave absorbing member 80. For example, in the tape member 91, the electric wire member 25 is arranged inside the through hole 81 so as to be in contact with a part of the inner peripheral surface of the through hole 81 and to be offset to a part in the circumferential direction of the through hole 81. It is wound around the outer peripheral surfaces of the electromagnetic wave absorbing member 80 and the electric wire member 25. Here, the inner peripheral surface of the through hole 81 has a first portion 81A, the first portion 81A thereof, and a second portion 81B arranged at a position symmetrical with respect to the central axis of the through hole 81. There is. At this time, the electric wire member 25 is in contact with the first portion 81A and separated from the second portion 81B inside the through hole 81. For example, a part of the covering member 70 is in contact with the first portion 81A and separated from the second portion 81B inside the through hole 81. Here, the first portion 81A with which the electric wire member 25 comes into contact has an electromagnetic wave covered by the tape member 91 rather than the second portion 81B in a direction intersecting the central axis direction in which the central axis passing through the center of the through hole 81 extends. It is provided at a position close to the region 84, which is the outer peripheral surface of the absorbing member 80. The first portion 81A is, for example, the inner peripheral surface of the through hole 81 of the portion corresponding to the region 84 in the circumferential direction of the electromagnetic wave absorbing member 80. For example, the first portion 81A is a portion located at the same angle as the region 84 of the outer peripheral surface 82A of the magnetic core 82 in the circumferential direction of the magnetic core 82. For example, the first portion 81A is a portion of the inner peripheral surface of the through hole 81 located on the back side of the region 84. The tape member 91 of this modified example absorbs electromagnetic waves so that, for example, the electric wire member 25 is brought into contact with the first portion 81A inside the through hole 81 and is arranged offset to the first portion 81A side (region 84 side). The member 80 is fixed to the outer periphery of the electric wire member 25. In other words, in the electromagnetic wave absorbing member 80, the outer peripheral surface of the electric wire member 25 (here) by the tape member 91 in a state where the electric wire member 25 is in contact with the first portion 81A and is offset toward the first portion 81A inside the through hole 81. Is fixed to the outer peripheral surface of the covering member 70). The plurality of electric wires 20 of this modified example are provided so as to be arranged in a direction intersecting a straight line connecting the first portion 81A and the second portion 81B, for example. The electric wire member 25 is arranged, for example, in the same direction over the entire length of the through hole 81 in the central axis direction, that is, on the region 84 side.

According to this configuration, the electromagnetic wave absorbing member 80 and the electric wire member 25 are fixed in a state where the electric wire member 25 is in contact with the first portion 81A and is arranged offset to the first portion 81A side inside the through hole 81. (Integrated). Therefore, even when the electromagnetic wave absorbing member 80 vibrates due to the traveling of the vehicle or the like, it is possible to prevent the electric wire member 25 from being shaken in the through hole 81 due to the vibration of the electromagnetic wave absorbing member 80. For example, as compared with the case where the electromagnetic wave absorbing member 80 and the electric wire member 25 are fixed in a state where the electric wire member 25 does not contact the inner peripheral surface of the through hole 81, the electric wire member 25 penetrates due to the vibration of the electromagnetic wave absorbing member 80. It is possible to suppress the movement in the hole 81. Thereby, it is possible to suppress the wear of the electric wire member 25 due to the contact with the inner peripheral surface of the through hole 81, and it is possible to preferably suppress the damage of the electric wire member 25 due to the vibration of the electromagnetic wave absorbing member 80. .. Further, since it is possible to suppress the electric wire member 25 from being shaken in the through hole 81, it is possible to suppress the generation of abnormal noise between the electromagnetic wave absorbing member 80 and the electric wire member 25.

-In the above embodiment, the electric wire member 25 is composed of the electric wire 20 and the covering member 70, but the present invention is not limited to this. For example, the electric wire member 25 may be formed only by the electric wire 20. That is, the covering member 70 may be omitted. In the modified example shown in FIG. 11, when the covering member 70 is omitted, for example, the outer peripheral surface of the electric wire 20 is brought into contact with the first portion 81A of the inner peripheral surface of the through hole 81.

-In the above embodiment, the corrugated tube 40 is embodied as the first exterior member, and the corrugated tube 60 is embodied as the second exterior member, but the present invention is not limited to this. For example, as the first exterior member and the second exterior member, a hard resin pipe, a metal pipe, or a rubber waterproof cover can be used. For example, the first exterior member and the second exterior member may be embodied in different types of exterior members.

For example, as shown in FIG. 12, the first exterior member may be embodied in a metal pipe 140, and the second exterior member may be embodied in a corrugated tube 60.

For example, the pipe 140 has a tubular shape that collectively surrounds the outer circumferences of the plurality of electric wires 20 as a whole. The outer peripheral surface of the pipe 140 is formed, for example, as a smooth surface. As the material of the pipe 140, for example, a metal material such as copper-based or aluminum-based can be used. The pipe 140 has, for example, a function of electromagnetically shielding a plurality of electric wires 20 at once and a function of protecting the plurality of electric wires 20 from flying objects and water droplets.

The pipe 140 is provided so as to surround the outer periphery of the end portion of the covering member 70, for example. The pipe 140 is provided so as to surround a part of the outer circumference of the tape member 91, for example. The covering member 70 and the tape member 91 reduce or prevent the electric wire 20 from being damaged by the edge of the pipe 140.

For example, the end of the braided member 100 is connected to the outer peripheral surface of the end of the pipe 140 in the length direction. The end portion of the braided member 100 in the length direction is connected to the outer peripheral surface of the pipe 140 by a caulking ring 150 provided on the outer peripheral side of the braided member 100, for example, in a state of being in direct contact with the outer peripheral surface of the pipe 140. There is. The caulking ring 150 is fitted to the outside of the pipe 140, for example, in such a manner that the end portion of the braided member 100 is sandwiched between the caulking ring 150 and the outer peripheral surface of the pipe 140. Then, the caulking ring 150 is tightened inward in the radial direction of the pipe 140, so that the end portion of the braided member 100 is fixed in direct contact with the outer peripheral surface of the pipe 140. As a result, the electrical continuity between the braided member 100 and the pipe 140 is stably ensured.

As the material of the caulking ring 150, for example, a copper-based, iron-based or aluminum-based metal material can be used. The material of the caulking ring 150 is preferably, for example, a metal material of the same type as the metal material constituting the pipe 140.

The cushioning member 110 is provided so as to surround the outer periphery of the electromagnetic wave absorbing member 80 provided between the pipe 140 and the corrugated tube 60, for example. The cushioning member 110 is provided so as to be bridged between the outer circumference of the pipe 140 and the outer circumference of the corrugated tube 60, for example. For example, one end of the cushioning member 110 in the length direction is fixed to the outer peripheral surface of the pipe 140 by the fixing member 120, and the other end in the length direction is fixed to the outer peripheral surface of the corrugated tube 60 by the fixing member 130. ing. The cushioning member 110 is fixed to the outer circumference of the pipe 140 so as to cover the outer circumference of the caulking ring 150, for example. In other words, the caulking ring 150 is housed in the internal space of the cushioning member 110. According to this configuration, since the caulking ring 150 is covered with the cushioning member 110, it is possible to suppress the generation of abnormal noise due to the contact between the caulking ring 150 and the peripheral parts.

-In the above modification example, the caulking ring 150 is used as a connecting member for fixing the end portion of the braided member 100 to the outer peripheral surface of the pipe 140 in a state of being electrically connected, but the present invention is not limited to this. For example, instead of the caulking ring 150, a metal band, a resin binding band, an adhesive tape, or the like may be used as the connecting member.

An adhesive layer or an adhesive layer may be provided on one surface of the cushioning member 110 of the above embodiment. For example, an adhesive layer or an adhesive layer may be provided on one surface of the end 113 of the cushioning member 110. According to this configuration, when the end portion 113 is overlapped with the end portion 112 of the cushioning member 110, the end portion 113 can be adhered to the end portion 112. As a result, it is possible to preferably prevent the cushioning member 110 from returning to the sheet state before being fixed by the fixing

members

120 and 130.

-In the above embodiment, the cushioning member 110 is embodied in a sheet-like structure having slits 111 extending along the length direction of the electric wire 20, but the present invention is not limited to this.

For example, as shown in FIG. 13, the cushioning member 110 may be embodied in a tubular structure having no slit extending along the length direction of the electric wire 20. The cushioning member 110 of this modified example is formed so as to surround the outer circumference of the electromagnetic wave absorbing member 80 over the entire circumference in the circumferential direction. For example, the cushioning member 110 of this modification is already formed as a cylinder from the state before the electromagnetic wave absorbing member 80 is arranged inside.

-In the above embodiment, the covering member 70 is embodied in a structure having a slit 71 extending along the length direction of the electric wire 20, but the present invention is not limited to this.

For example, as shown in FIG. 13, the covering member 70 may be embodied in a tubular structure having no slit extending along the length direction of the electric wire 20. The covering member 70 of this modified example is formed so as to surround the outer circumferences of the plurality of electric wires 20 over the entire circumference in the circumferential direction. For example, the covering member 70 of this modification is already formed as a tubular body from the state before the electric wire 20 is arranged inside.

-In the above embodiment, the braided member 100 is provided so as to cover the outer periphery of the electromagnetic wave absorbing member 80, but the present invention is not limited to this. For example, the braided member 100 may be passed through the through hole 81 of the electromagnetic wave absorbing member 80.

-Instead of the braided member 100 of the above embodiment, it may be changed to another electromagnetic shield member such as a metal foil.

-The braided member 100 in the above embodiment may be omitted.

-The electric wire 20 of the above embodiment may be changed to a shielded electric wire.

-In the above embodiment, the electromagnetic wave absorbing member 80 is composed of only the magnetic core 82, but the present invention is not limited to this. For example, the electromagnetic wave absorbing member 80 may include a magnetic core 82 and a case for accommodating the magnetic core 82.

-The number and installation positions of the electromagnetic wave absorbing members 80 in the above embodiment are not particularly limited. For example, two or more electromagnetic wave absorbing members 80 may be provided for the wire harness 10. For example, the electromagnetic wave absorbing member 80 may be provided outside the vehicle interior, which is a waterproof region.

-The winding method of the tape member 91 of the above embodiment is not particularly limited. For example, the tape member 91 may be formed so as to cover the entire outer peripheral surface of the electromagnetic wave absorbing member 80.

-In the above embodiment, the fixing member 90 is composed of the tape member 91, but the present invention is not limited to this. For example, as the fixing member 90, a metal band or a resin binding band can be used.

-In the above embodiment, the number of electric wires 20 housed inside the exterior member 30 is two, but the number is not particularly limited, and the number of electric wires 20 can be changed according to the specifications of the vehicle V. .. For example, the number of electric wires 20 housed inside the exterior member 30 may be one or three or more. For example, as an electric wire housed in the exterior member 30, a low-voltage electric wire for connecting a low-voltage battery and various low-voltage devices (for example, a lamp, a car audio, etc.) may be added.

-The arrangement relationship between the inverter 11 and the high-voltage battery 12 in the vehicle V is not limited to the above embodiment, and may be appropriately changed according to the vehicle configuration.

For example, as shown in FIG. 14, the high-voltage battery 12 may be arranged substantially on the floor of the vehicle V, and may be embodied in a wire harness 10 that electrically connects the high-voltage battery 12 and the inverter 11.

-In the above embodiment, the inverter 11 and the high-voltage battery 12 are adopted as the electric devices connected by the wire harness 10, but the present invention is not limited to this. For example, it may be used for an electric wire connecting the inverter 11 and the motor for driving the wheels. That is, it is applicable as long as it electrically connects the electric devices mounted on the vehicle V.

As shown in FIGS. 2 and 3, an empty space may be formed between the inner peripheral surface of the porous buffer member 110 and the outer peripheral surface of the braided member 100. This empty space is deformed by the deformation of the porous cushioning member 110 and / or the deformation of the braided member 100, and the inner peripheral surface of the porous cushioning member 110 and the outer peripheral surface of the braided member 100 partially contact each other. You can do it.

-In some mounting examples, the porous buffer member 110 may be a soft or flexible, synthetic resin sponge, or a soft or flexible sheet-like synthetic resin sponge. In general, since the corrugated tube can be reversibly expanded and contracted in the length direction, for example, in the embodiment of FIG. 2, the separation distance between the open end of the corrugated tube 40 and the open end of the corrugated tube 60 may vary. The same applies to the embodiment shown in FIG. In this respect, when the porous buffer member 110 is soft or flexible, it is possible to flexibly cope with fluctuations in the separation distance between the open ends of the two exterior members to which the porous buffer member 110 is fixed. When the porous cushioning member 110 is a synthetic resin sponge, the cushioning member 110 is easily available. When the porous buffer member 110 is a soft or flexible sheet-like synthetic resin sponge, a roll of the porous buffer member 110 can be easily formed, and exterior members such as

corrugated tubes

40 and 60 can be easily formed. The work of winding the porous cushioning member 110 around the outer peripheral surface of the is facilitated.

-In some mounting examples, the porous buffer member 110 can have a relatively low bulk density. For example, the bulk density of the porous buffer member 110 may be a part of other elements (eg, an electromagnetic wave absorbing member 80, an electric wire member 25, and a braided member 100) arranged inside the porous buffer member 110. It may be lower than that of all). In some mounting examples, the bulk density of the porous buffer member 110 is lower than that of the electromagnetic wave absorbing member 80, lower than that of the wire member 25, and lower than that of the braided member 100. In a certain mounting example, among the porous buffer member 110, the electromagnetic wave absorbing member 80, the electric wire member 25, the braided member 100, and the

exterior members

40 and 60, the porous buffer member 110 has the lowest bulk density. If the bulk density of the porous buffer member 110 is low, for example, the porous buffer member 110 hardly vibrates or the vibration of the porous buffer member 110 is rapidly damped while the vehicle is running. Such a low bulk density porous buffer member 110 is one of other elements (for example, an electromagnetic wave absorbing member 80, an electric wire member 25, and a braided member 100) arranged inside the porous buffer member 110. It is advantageous to absorb or attenuate the vibration of a part or all) by direct or indirect vibration propagation. Further, the low bulk density porous buffer member 110 is advantageous for absorbing or attenuating vibrations of exterior members such as

corrugated tubes

40 and 60 that come into direct contact with the low bulk density porous buffer member 110. .. Thus, the porous cushioning member 110 is advantageous for absorbing or attenuating vibrations generated by other elements of the wire harness 10 and is also disposed inside the porous cushioning member 110. It is advantageous to reduce the sound generated by the element from leaking to the outside of the wire harness 10. Further, the low bulk density porous buffer member 110 is relatively lightweight and is advantageous for the vehicle wire harness 10.

-The electromagnetic wave absorbing member 80 of the embodiment may be referred to as an electromagnetic noise filter coaxially attached to the electric wire 20. The porous cushioning member 110 of the embodiment may be referred to as a roll of soft or flexible sheet-like synthetic resin sponge.
