  By the way, when attaching the clamp which has a part which pinches | interposes a member like the clamp of patent document 2 to the exterior member attached to an electric wire, there exists a possibility that the structure by the side of an exterior member may become complicated. For example, when forming an exterior member by bending a plate material, it may be difficult to form a structure that fits into a clamp.

  Then, an object of this invention is to provide the technique which can attach the clamp which has a part which pinches | interposes a member to the exterior member attached to an electric wire with a simpler structure.

  In order to solve the above problem, the electric wire module according to the first aspect is attached to the electric wire so as to cover at least one electric wire and at least a part of the periphery of the electric wire. A protruding portion including a protective portion in which an opening is formed, and a biasing portion that protrudes in a direction to close the opening from a part of an inner peripheral edge of the opening and is elastically deformable along the protruding direction. A holding member that sandwiches a portion of the inner peripheral edge of the opening that faces the biasing portion, and an engaging portion that protrudes on an outer surface of the clamping portion, and the clamping portion Includes a clamp that is biased toward the inner peripheral edge of the opening by the biasing portion of the protrusion.

  The electric wire module which concerns on a 2nd aspect is an electric wire module which concerns on a 1st aspect, Comprising: The said protection part of the said exterior member is formed by bending a board | plate material.

  The electric wire module which concerns on a 3rd aspect is an electric wire module which concerns on a 1st or 2nd aspect, Comprising: As for the said urging | biasing part, a peak part and a trough part continue in succession along the protrusion direction of the said protrusion part. Including bellows.

  The electric wire module which concerns on a 4th aspect is an electric wire module which concerns on any one 1st-3rd aspect, Comprising: The said urging | biasing is carried out from the outer peripheral surface of the side contact | abutted to the said urging | biasing part. A notch is formed toward the front in the urging direction of the portion, and the protruding portion further includes an insertion portion provided at the tip thereof and formed to be insertable into the notch.

  The electric wire module which concerns on a 5th aspect is an electric wire module which concerns on any one 1st-4th aspect, Comprising: The said protection part of the said exterior member is formed using the hollow plate material or the nonwoven fabric as a material.

  According to the electric wire module which concerns on the 1st-5th aspect, while an exterior member protrudes in the direction which closes opening from the protection part in which opening is formed, and a part of inner peripheral part of opening, in the protrusion direction And a projecting portion including a biasing portion formed so as to be elastically deformable along the clamp, and sandwiched by the biasing portion of the projecting portion with the inner peripheral edge portion of the opening being sandwiched between the clamping portions of the clamp By biasing the part, the clamp is difficult to come off from the exterior member. Thereby, the clamp which has a part which pinches | interposes a member to the exterior member attached to an electric wire can be attached with a simpler structure.

  In particular, according to the electric wire module according to the second aspect, the protective portion of the exterior member is formed by bending the plate material. Even in this case, a clamp having a portion for sandwiching a member in an exterior member attached to an electric wire can be simplified by energizing the energizing portion in a state in which a part of the plate material constituting the protection portion is sandwiched between the nipping portions. It can be attached with a simple structure.

  In particular, according to the electric wire module according to the third aspect, the urging portion includes a bellows portion in which peaks and troughs are alternately continued along the protruding direction of the protruding portion, and thus the urging portion is urged with a simpler structure. The part can be formed.

  In particular, according to the electric wire module according to the fourth aspect, the notch is formed in the holding portion from the outer peripheral surface on the side in contact with the urging portion toward the front in the urging direction by the urging portion. Since it further includes an insertion portion that is provided at the tip and is formed so as to be insertable into the notch, the urging force can be more reliably transmitted to the clamp. Thereby, a clamp becomes difficult to remove | deviate from an exterior member.

  In particular, according to the electric wire module according to the fifth aspect, the protective portion of the exterior member is formed using a hollow plate material or a non-woven fabric as a material, so that the electric wire module can be reduced in weight.

{Embodiment}
Hereinafter, the electric wire module 10 which concerns on embodiment is demonstrated. Drawing 1 is a perspective view showing electric wire module 10 concerning an embodiment. FIG. 2 is a plan view showing the electric wire module 10 according to the embodiment. 3 is a schematic cross-sectional view taken along line III-III in FIG. FIG. 4 is a view of the peripheral portion of the opening 24 as seen from the bottom surface side.

  The electric wire module 10 according to the embodiment includes an electric wire 12, an exterior member 20, and a clamp 40.

  It is sufficient that at least one electric wire 12 is included. The intermediate portion of the electric wire 12 is protected by the exterior member 20. The electric wire 12 is configured such that a covering portion is formed by extrusion coating of resin on the outer periphery of the core wire. Here, an example of an electric wire bundle in which a plurality of electric wires 12 are bundled will be described. An optical fiber or the like may be disposed along the electric wire 12 in the electric wire bundle. The electric wire 12 is used to electrically connect various electric devices mounted on a vehicle or the like in a state where the electric wire 12 is arranged at a location to be arranged on the vehicle or the like. In addition, in FIG.1 and FIG.2, the outline of the wire bundle is drawn.

  The exterior member 20 is attached around the electric wire 12. Here, the exterior member 20 is formed in a cylindrical shape that can accommodate the intermediate portion in the longitudinal direction of the electric wire 12. In the description of the exterior member 20, FIGS. 5 and 6 are also referred to in addition to FIGS. FIG. 5 is a perspective view showing a state of the protrusion 30 before the urging portion 32 is elastically deformed. FIG. 6 is a perspective view showing a state of the protruding portion 30 after the urging portion 32 is elastically deformed. Specifically, the exterior member 20 includes a protection part 22 and a protruding part 30.

  The protection part 22 is attached to the electric wire 12 so as to cover at least a part of the periphery of the electric wire 12. Here, the protection unit 22 is made of a plate material. Furthermore, here, the protection part 22 is formed in a square cylinder shape that covers the four sides of the electric wire 12 by bending the plate material at a crease, and is formed so as to be able to accommodate the longitudinal intermediate portion of the electric wire 12.

  Such a bendable plate material has a rigidity that can protect the electric wire 12 in a state where the electric wire 12 is covered (preferably a rigidity that can restrict the path of the electric wire 12), and can be bent. Those having (preferably bendable properties) may be used.

  As such a plate material, it is preferable to use a hollow plate material 80 in which a hollow structure is formed between a plurality of plate-like portions. This is because the hollow plate member 80 having such a hollow structure can provide the protective part 22 material that is light and excellent in strength.

  Here, the configuration of such a hollow plate member 80 will be described first. FIG. 11 is a partially cutaway perspective view showing an example of the hollow plate member 80.

  The hollow plate member 80 includes a plurality (two in this case) of plate-like portions 82 and an interposition portion 84 sandwiched between the plurality of plate-like portions 82.

  The material which forms the some plate-shaped part 82 and the interposition part 84 is not specifically limited. The plurality of plate-like portions 82 and the intervening portions 84 may be formed of paper, may be formed of resin, or may be configured by a combination thereof. When at least one of the plurality of plate-like portions 82 and the intervening portion 84 is formed of paper, it is preferable to perform a water repellent treatment or the like on the surface.

  The plate-like portion 82 is formed in a flat plate shape. A plurality of plate-like portions 82 are connected via an intervening portion 84 at intervals.

  Here, a plurality of interposition portions 84 are provided between the plurality of plate-like portions 82 in a parallel state with a space therebetween.

  Each interposition part 84 is formed in an elongated plate shape, and is connected to the plate-like part 82 in a posture orthogonal to the plate-like parts 82 on both sides.

  For this reason, when the hollow plate member 80 is cut along a plane orthogonal to the extending direction of the interposition part 84, a ladder-like cross section in which a plurality of interposition parts 84 exist in parallel between the pair of plate-like parts 82 is shown. .

  Such a hollow plate member 80 can be continuously manufactured by, for example, an extrusion molding apparatus that extrudes a resin from an extrusion hole corresponding to the ladder-like cross section, thereby easily manufacturing the plate member at low cost. be able to. Alternatively, the hollow plate member 80 can also be manufactured by joining the two plate-like portions 82 to both sides of the plurality of interposition portions 84 arranged in parallel with each other by heat welding, an adhesive, or the like.

  The example of the board | plate material which has a hollow structure is not restricted to the said example. For example, the plate member may have a configuration in which an intervening portion in which a crest and a trough are continuous in a wave shape is sandwiched between a plurality of plate-like portions. Alternatively, the plate material may be one in which intervening portions present between a plurality of plate-like portions form a polygonal columnar hollow shape such as a triangular prism, and in particular, a honeycomb structure. .

  Of these plate materials having a hollow structure, those made of resin may be called plastic corrugated cardboard.

  The following advantages can be obtained by forming the protection part 22 using the hollow plate 80 as a material. That is, the hollow plate member 80 has a plurality of interposition portions 84 arranged in parallel with a gap, and thus is difficult to bend along the extending direction of the interposition portions 84, but is easy to bend along the parallel direction of the interposition portions 84. . At this time, the hollow plate member 80 is provided on the other plate by providing a slit along the extending direction of the interposition part 84 in a portion of the one plate-like part 82 sandwiching the interposition part 84 that is not in contact with the interposition part 84. The portion of the shaped portion 82 that faces the slit is more likely to bend with a crease. Further, the strength of the hollow plate 80 is excellent due to the structure forming the hollow structure. Furthermore, since the hollow plate member 80 has a hollow structure, it is relatively lightweight for its strength. Further, the material used for the hollow plate 80 is also small for the strength. For this reason, material cost can be held down.

  But it is not essential that the protection part 22 is formed of the hollow plate 80. The protection part 22 may be formed of a flat plate like the plate-like part 82 of the hollow plate 80. Moreover, the protection part 22 may be formed with the nonwoven fabric etc. Details will be described later as a modification.

  In addition, when a protection part is resin-molded, it is not difficult to form the lock mechanism which can be fitted with the clamp 40 in a protection part. However, when the protection part 22 is formed by folding the plate material, particularly when the protection part 22 is formed by folding the hollow plate material 80, it is for fitting the clamp 40 on the protection part 22 side. It is difficult to form a locking mechanism. In the present invention, the protection part 22 is formed by folding the plate material as described above. In particular, even when the protection part 22 is formed by folding the hollow plate material 80, the protection is made as simple as possible. The clamp 40 can be attached to the portion 22. However, it goes without saying that the present invention may be applied to a case where the protective portion is resin-molded.

  But it is not essential that a protection part encloses the four sides of the electric wire 12. FIG. For example, the protection part may be formed in such a manner as to surround three sides of the electric wire 12 and one side is open. That is, the protection part 22 should just cover at least one part of the circumference | surroundings of the electric wire 12. FIG.

  In addition, the protection part 22 and the electric wire 12 are good to be fixed with the tape or the binding band.

  1 to 6, an opening 24 is formed in an intermediate portion on the outer peripheral surface of the protection portion 22.

  Specifically, here, the opening 24 is formed in a surface that does not include the width direction end portion of the plate material in the protection portion 22 that is formed into a rectangular tube shape by folding the plate material. The opening 24 is provided in an intermediate portion in the width direction and the longitudinal direction of the surface. The opening 24 is provided as a through hole having a quadrangular shape (in this case, a rectangular shape) in plan view.

  The width dimension of the opening 24 (the dimension of the short side of the rectangle) is set to be the same as or larger (slightly larger here) than the width dimension of the clamping portion 42 of the clamp 40 described later. Further, the longitudinal dimension of the opening 24 (long rectangular side dimension) is set larger than the longitudinal dimension of the clamping portion 42 of the clamp 40. Accordingly, the inner peripheral edge portion 26 of the opening 24 can be sandwiched in the sandwiching portion 42 of the clamp 40 by sliding the sandwiching portion 42 of the clamp 40 after inserting the sandwiching portion 42 of the clamp 40 into the opening 24.

  The protruding portion 30 is formed so as to protrude in a direction of closing the opening 24 from a part of the inner peripheral edge portion 26 of the opening 24. The protrusion 30 is in a normal state and closes the opening 24. The protrusion 30 is provided so that the opening 24 can be opened by elastic deformation so that the clamp 40 can be inserted into the opening 24.

  Further, the projecting portion 30 abuts against the sandwiching portion 42 sandwiching the inner peripheral edge portion 26 of the opening 24 from the side opposite to the sandwiching portion 42 and attaches from the contact portion toward the sandwiched portion. It is provided to be ready. Here, the protruding portion 30 protrudes from one short side portion of the inner peripheral edge portion 26 of the opening 24 toward the other short side portion. The protrusion 30 includes an urging portion 32. Furthermore, here, the protrusion 30 includes an insertion portion 36.

  Here, the protruding portion 30 is formed by using a part of the protective portion 22 that is not required when the opening 24 is formed in the protective portion 22, but will be described in detail later.

  The urging portion 32 is formed to be elastically deformable along the protruding direction of the protruding portion 30. Here, the urging portion 32 includes a bellows portion 34 in which crest portions 34 a and trough portions 34 b continue alternately along the protruding direction of the protruding portion 30. Further, here, the urging portion 32 is provided so as to protrude from the inner peripheral edge portion 26 of the opening 24.

  However, it is not essential that the urging portion 32 includes the bellows portion 34. The urging portion 32 may have another elastically deformable configuration such as a spring, for example. However, since the biasing portion 32 includes the bellows portion 34, the remaining section can be used as the biasing portion 32 when the protective portion 22 is cut out to form the opening 24.

  Further, it is not essential that the biasing portion 32 protrudes from the inner peripheral edge portion 26 of the opening 24. The urging portion 32 only needs to be provided on at least a part of the protruding portion 30 that protrudes from the inner peripheral edge portion 26 of the opening 24 and contacts the rear end of the clamp 40.

  The insertion portion 36 is provided at the tip of the protruding portion 30. The insertion part 36 is formed so as to be insertable into a notch 49 formed in the clamping part 42 of the clamp 40 described later.

  Specifically, the insertion portion 36 is here formed in an elongated flat plate shape, and is less likely to be elastically deformed than the protruding portion 30. The width of the insertion portion 36 is set to be the same as or smaller than the width of the notch 49 formed in the clamp 40 (here, substantially the same). Thereby, the insertion part 36 can be inserted into the notch 49 of the clamp 40.

  In addition, the dimension of the longitudinal direction of the insertion part 36 can take arbitrary values. However, the longitudinal dimension of the insertion portion 36 is preferably set to be the same as the longitudinal dimension of the notch 49. Here, when the longitudinal dimension of the insertion portion 36 is set to be equal to or smaller than the longitudinal dimension of the notch 49, the urging portion 32 contacts the rear end of the clamping portion 42 of the clamp 40. , Can convey the biasing force more reliably. Further, the longer the dimension in the longitudinal direction of the insertion portion 36 is, the more difficult it is for the insertion portion 36 to be detached from the notch 49 of the clamp 40. In other words, when the longitudinal dimension of the insertion portion 36 is set to be the same as the longitudinal dimension of the notch 49, the insertion portion 36 is unlikely to be detached from the notch 49 of the clamp 40, and the urging portion 32 is clamped. The urging force can be transmitted more reliably by coming into contact with the rear end of the 40 clamping portions 42.

  However, it is not essential that the protrusion 30 includes the insertion portion 36, and the protrusion 30 may not include the insertion portion 36. Further, even when the protruding portion 30 includes the insertion portion 36, it is not essential that the insertion portion 36 is less likely to be elastically deformed than the biasing portion 32. As long as the insertion part 36 can be inserted into at least the notch 49 of the clamp 40, for example, the insertion part 36 may be formed in a bellows shape similar to the biasing part 32.

  Here, the opening 24 and the protruding portion 30 are formed by cutting a part of the plate material constituting the protection portion 22. More specifically, three sides (here, a portion corresponding to two long sides and one short side of a rectangle) are cut out by a part on one surface of the plate member constituting the protection unit 22. As a result, a section in which one end is connected to the protection portion 22 and the other end is a free end is blocking the opening 24. The base end side of the section is folded into a bellows shape to form an urging portion 32, and the width direction both sides are cut so that the width on the distal end side is narrowed to form an insertion section 36, and the entire section is formed. The protrusion 30 is formed. In the normal state as shown in FIG. 5, the opening 24 is substantially blocked by the protrusion 30. However, the opening 24 appears by elastically deforming the bellows 34 so as to contract as shown in FIG. With the opening 24 thus appearing, the clamping portion 42 of the clamp 40 is inserted and slid into the opening 24 to slide the inner peripheral edge portion 26 of the opening 24 in the protective portion 22 and the protruding direction of the protruding portion 30. A clamp 40 is attached to a portion located on the distal end side.

  In addition, although the protrusion direction of the protrusion part 30 is set here so that it may become parallel to the longitudinal direction of the protection part 22, ie, the longitudinal direction of the electric wire 12, this is not essential. The protruding direction of the protruding part 30 may be a direction that forms an angle with the longitudinal direction of the protective part 22, for example, a direction orthogonal to the longitudinal direction of the protective part 22.

  The clamp 40 is formed to be attachable to an attachment object. Here, the clamp 40 is formed to be able to be locked in a through hole formed in the panel. The clamp 40 includes a clamping part 42 and an engaging part 50. In describing the clamp 40, FIGS. 7 to 10 are referred to in addition to FIGS. FIG. 7 is a front view showing the clamp 40. FIG. 8 is a side view showing the clamp 40. FIG. 9 is a plan view showing the clamp 40. FIG. 10 is a bottom view showing the clamp 40.

  The sandwiching portion 42 sandwiches a portion of the inner peripheral edge portion 26 of the opening 24 that faces the biasing portion 32. The sandwiching portion 42 sandwiching the inner peripheral edge portion 26 of the opening 24 is urged toward the inner peripheral edge portion 26 of the opening 24 by the urging portion 32 of the projecting portion 30. Moreover, the notch 49 in which the insertion part 36 of the protrusion part 30 fits is formed in the clamping part 42. FIG. The notch 49 is formed from the outer peripheral surface in contact with the urging portion 32 toward the front in the urging direction by the urging portion 32.

  Specifically, the sandwiching portion 42 includes a first contact portion 44 that contacts one main surface of the inner peripheral edge portion 26 of the opening 24, a second contact portion 46 that contacts the other main surface, A connecting portion 48 that connects the first contact portion 44 and the second contact portion 46 is included.

  The first abutting portion 44 is provided with an engaging portion 50 on the opposite surface of the inner peripheral edge portion 26 of the opening 24 from the side that abuts on one main surface.

  The second contact portion 46 is formed with a notch 49 into which the insertion portion 36 of the protruding portion 30 is fitted. More specifically, the second abutting portion 46 includes a pair of abutting pieces 46a arranged in parallel, and a connecting piece 46b that connects the pair of abutting pieces 46a at respective intermediate portions, and the bottom surface of FIG. It is formed in a shape close to an H shape in view. From another viewpoint, the second contact portion 46 has a shape in which a notch 49 along the longitudinal direction is formed in the intermediate portion in the width direction of the rectangular plate. The insertion portion 36 of the protruding portion 30 is inserted into the notch 49, that is, a space surrounded by the pair of contact pieces 46a and the connecting piece 46b.

  The distance between the first contact portion 44 and the second contact portion 46 is set to be equal to or smaller than the thickness of the protection portion 22 (here, slightly smaller). Thereby, the inner peripheral edge portion 26 of the opening 24 formed in the protection portion 22 can be sandwiched between the first contact portion 44 and the second contact portion 46.

  The length dimension of the connecting piece 46b (the distance between the pair of contact pieces 46a) is set to be the same as or larger than the width dimension of the insertion portion 36 (substantially the same here). Accordingly, the insertion portion 36 can be inserted into a space surrounded by the pair of contact pieces 46a and the connecting piece 46b.

  The connecting portion 48 is provided so as to connect the first contact portion 44 and the second contact portion 46. The connecting portion 48 serves as a stopper so that when the inner peripheral edge portion 26 of the opening 24 is inserted between the first contact portion 44 and the second contact portion 46, it is not further inserted. Here, the connecting portion 48 is located at the same position as the connecting piece 46b of the second abutting portion 46 in the direction in which the inner peripheral edge portion 26 of the opening 24 is inserted into the holding portion 42 (here, slightly more than the connecting piece 46b). It is formed at a position near the protrusion 30.

  The engaging part 50 is projected on the outer surface of the clamping part 42. Here, the engaging portion 50 is formed on the outer surface of the first abutting portion 44 in the clamping portion 42. The engaging portion 50 is formed so as to be fixable to an attachment target portion provided on the vehicle body panel. Here, the engaging part 50 is demonstrated by the example formed in the shape fitted in the hole formed in the vehicle body panel. Specifically, the engaging part 50 includes a shaft part 52, a wing part 54, and a dish part 56.

  The shaft portion 52 is provided so as to protrude from the first contact portion 44 in a manner orthogonal to the outer surface thereof.

  The wing portion 54 is provided so as to gradually spread from the tip of the shaft portion 52 toward the clamping portion 42 side. Further, the wing portion 54 is formed so as to be elastically deformable so as to be able to pass through the hole formed in the vehicle body panel. It is formed so as to be caught by the peripheral edge portion 26.

  The dish part 56 is formed in a dish shape, and is provided at the base end part of the shaft part 52 so that the outer edge thereof is on the wing part 54 side. The dish part 56 functions as a disk spring when it contacts the vehicle body panel.

  With the wings 54 fitted in the holes formed in the vehicle body panel, the inner peripheral edge of the hole in the vehicle body panel is located between the wings 54 and the dish 56. With this state, the engaging portion 50 is fixed in a hole formed in the vehicle body panel.

  In addition, it is not essential that the engaging part 50 is formed in a shape that fits into a hole formed in the vehicle body panel. For example, the engaging part 50 may be formed in a shape that can be locked to the stud bolt. That is, the engaging part 50 should just be formed in the shape according to the structure of the attachment object part provided in the vehicle body panel so that it can fix to the attachment object part provided in the vehicle body panel.

<Installation work>
Next, an operation for attaching the clamp 40 to the exterior member 20 will be described.

  In order to attach the clamp 40 to the exterior member 20, first, the urging portion 32 is elastically deformed so as to contract as shown in FIG. Then, with the opening 24 opened, the clamping portion 42 of the clamp 40 is inserted into the opening 24.

  When the clamping portion 42 of the clamp 40 is inserted into the opening 24, the clamp 40 is positioned so that the inner peripheral edge portion 26 of the opening 24 is positioned between the first contact portion 44 and the second contact portion 46 in the height direction. Adjust the height. In this state, the inner peripheral edge 26 of the opening 24 is inserted into the clamping part 42 by sliding the clamp 40 toward the inner peripheral edge 26. When the inner peripheral edge 26 comes into contact with the connecting portion 48 and can no longer be inserted, the insertion of the inner peripheral edge 26 of the opening 24 into the clamp 40 is completed.

  When the insertion of the inner peripheral edge portion 26 of the opening 24 into the clamp 40 is completed, the insertion portion 36 of the protruding portion 30 is inserted into the notch 49 and the urging portion 32 is brought into contact with the clamping portion 42. Thereby, the attachment work of the clamp 40 to the exterior member 20 is complete | finished.

  In addition, after inserting the clamp 40 into the opening 24 and before the insertion of the inner peripheral edge portion 26 of the opening 24 into the clamp 40, the force by which the operator elastically deforms the protruding portion 30 is applied. It may be left or released. In the stage before the insertion of the inner peripheral edge 26 of the opening 24 to the clamp 40, when the force that elastically deforms the protrusion 30 by the operator is released, the insertion section 36 is inserted into the notch 49 at this stage. The urging unit 32 may be brought into contact with the clamping unit 42. This facilitates insertion when the inner peripheral edge 26 of the opening 24 is inserted into the clamp 40.

<Operation of clamp 40 and protrusion 30 when force is applied>
Next, the operation of the clamp 40 and the protrusion 30 when a force is applied to the clamp 40 attached to the exterior member 20 will be described.

  The force applied to the clamp 40 attached to the exterior member 20 is decomposed into a force in the protruding direction of the protruding portion 30 and a force in a direction orthogonal to the protruding direction.

  Among these, the first abutment is applied to a force in a direction perpendicular to the protruding direction and connecting the first abutment portion 44 and the second abutment portion 46 (the thickness direction of the protection portion 22). The part 44 or the second contact part 46 is canceled by the reaction force of the force pressing the inner peripheral edge part 26 of the opening 24 sandwiched therebetween. In addition, the first contact portion 44 or the second contact portion 46 and the opening 24 sandwiched between the first contact portion 44 and the second contact portion 46 with respect to the force in the width direction of the sandwiching portion 42 in a direction orthogonal to the protruding direction. It is canceled out by the frictional force between the peripheral part 26 and the peripheral part 26. Even when the frictional force does not cancel out, since the dimension in the width direction of the opening 24 is set slightly larger than the dimension in the width direction of the sandwiching part 42, the sandwiching part 42 moves after the sandwiching part 42 moves slightly in the width direction. Is in contact with the inner peripheral edge portion 26 of the opening 24, so that the clamping portion 42 is offset by the reaction force of the force pressing the inner peripheral edge portion 26 of the opening 24.

  Further, the force in the protruding direction of the protruding portion 30 and in the direction from the protruding portion 30 toward the clamp 40 (the direction toward the front in the protruding direction) causes the connecting portion 48 to press the inner peripheral edge portion 26 of the opening 24. It is offset by the reaction force.

  The force in the projecting direction of the projecting portion 30 and in the direction from the clamp 40 toward the projecting portion 30 (the direction toward the rear in the projecting direction) is the same as that of the first contact portion 44 or the second contact portion 46. It is canceled by the frictional force between the inner peripheral edge portion 26 of the opening 24 sandwiched therebetween. Even when the frictional force does not cancel, the clamping part 42 is canceled by the reaction force of the force pressing the protruding part 30. At this time, the elastic force increases as the biasing portion 32 of the protruding portion 30 contracts, so that the reaction force of the force with which the clamping portion 42 presses the protruding portion 30 increases. Here, it is preferable that the reaction force immediately before the clamping portion 42 is removed from the opening is set to be larger than the maximum value of the force predicted to be applied to the clamp 40. Thereby, it can suppress more reliably that the clamp 40 remove | deviates from the exterior member 20. FIG.

  As described above, even when a force is applied to the clamp 40 attached to the exterior member 20, the clamp 40 is unlikely to be detached from the inner peripheral edge portion 26 of the opening 24.

  According to the electric wire module 10 according to the embodiment, the exterior member 20 protrudes in a direction to close the opening 24 from a part of the inner peripheral edge portion 26 of the protective portion 22 in which the opening 24 is formed and the opening 24, and the protrusion And the protruding portion 30 including the urging portion 32 formed so as to be elastically deformable along the direction. Therefore, the inner peripheral edge portion 26 of the opening 24 of the protection portion 22 is sandwiched in the clamping portion 42 of the clamp 40. By urging the clamping part 42 with the urging part 32 of the projecting part 30, the clamp 40 is difficult to come off from the exterior member 20. Thereby, the clamp 40 which has a part which pinches | interposes a member in the exterior member 20 attached to the electric wire 12 can be attached with a simpler structure.

  Moreover, the protection part 22 of the exterior member 20 is formed by bending a plate material. Even in this case, in a state where a part of the plate material constituting the protection portion 22 is sandwiched between the sandwiching portions 42, the portion that sandwiches the member in the exterior member 20 attached to the electric wire 12 is biased by the biasing portion 32. It is possible to attach the clamp 40 having a simpler structure.

  Moreover, since the urging | biasing part 32 contains the bellows part 34 with which the peak part 34a and the trough part 34b continue alternately along the protrusion direction of the protrusion part 30, the urging | biasing part 32 is formed with a simpler structure. Can do.

  Further, a notch 49 is formed in the clamping part 42 from the outer peripheral surface on the side in contact with the urging part 32 toward the front in the urging direction by the urging part 32, and the protruding part 30 is provided at the tip thereof, Since the insertion portion 36 that can be inserted into the notch 49 is further included, the urging force can be transmitted to the clamp 40 more reliably. Thereby, the clamp 40 is unlikely to be detached from the exterior member 20.

  Moreover, since the protection part 22 of the exterior member 20 is formed using the hollow plate 80 as a material, the electric wire module 10 can be reduced in weight.

{Modifications}
Next, the modification of the electric wire module 10 which concerns on embodiment is demonstrated. Here, the kind of material used for the exterior member 20 and how to make it will be described.

  Specifically, in the embodiment, the exterior member 20 has been described as being formed by bending the hollow plate member 80, but the exterior member 20 may be formed by bending a plate member other than the hollow plate member 80. It is done. For example, the exterior member 20 may be formed by bending a flat plate such as the plate-like portion 82 of the hollow plate member 80. In this case, the plate thickness of the flat plate is preferably thicker than the plate thickness of the plate-like portion of the hollow plate member 80. In addition, the exterior member 20 may be configured by bending and compressing a non-woven fabric into a rigid plate shape.

  Even when the exterior member 20 is formed by bending a flat plate or a non-woven plate, it can be formed in the same shape as the exterior member 20 formed of the hollow plate 80.

  Furthermore, when the exterior member 20 is formed by bending a nonwoven fabric plate, the fold is formed of a material that has flexibility by reducing the amount of heat compression of the nonwoven fabric. Also good. In this case, a plate part and a fold can be formed in one nonwoven fabric by providing the nonwoven fabric with a portion that increases and decreases the amount of heat compression.

  When the exterior member 20 is formed of a non-woven plate material, the weight of the electric wire module 10 can be reduced as in the case where the exterior member 20 is formed by bending the hollow plate material 80.

  In addition, the exterior member 20 has been described so far as being formed by bending a plate-shaped member, but the method of making the exterior member 20 is not limited to this. At least the protection part 22 of the exterior member 20 may be a so-called resin molded product made by pouring resin into a mold corresponding to the shape of the finished product. At this time, the opening 24 and the protruding portion 30 may be formed of a mold simultaneously with the protection portion 22. Further, for example, after forming the protection part 22 with a mold, it may be formed by cutting a part of the protection part 22 in three directions and making a section having a free end remaining after the opening into a bellows shape. .

  In addition, each structure demonstrated by the said embodiment and each modification can be suitably combined unless it mutually contradicts.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
