The protective member maintains the cylindrical shape by inserting the second end portion into the slit. That is, the first end and the second end are turned upside down across the first slit (the ends appearing on the surface of the protective member are different on both sides of the slit), so that the protective member maintains a cylindrical shape. Therefore, the protection member and the rod-shaped fixing member can be fixed with a simpler configuration.

  In particular, according to the wire harness support according to the second aspect, since the plurality of first slits are formed at intervals in the longitudinal direction of the protective member, the top and bottom are reversed between the first end and the second end.

{Embodiment}
Hereinafter, the wire harness support body 100 which concerns on embodiment is demonstrated. FIG. 1 is an explanatory diagram showing the location of reinforcement in the vehicle 80. FIG. 2 is a plan view showing the protection member 3 according to the embodiment. FIG. 3 is a perspective view showing a hollow plate 30 constituting the protection member 3 according to the embodiment. FIG. 4 is an explanatory diagram illustrating a state in which the protection member 3 according to the embodiment is attached to the fixing member 2. FIG. 5 is an upper perspective view showing the wire harness support 100 according to the embodiment.

  The wire harness support body 100 according to the embodiment includes a rod-shaped fixing member 2 and a protective member 3 that is formed into a tubular shape by bending a plate-shaped member. In the wire harness support 100, the protection member 3 is attached to the fixing member 2.

  In the present embodiment, the wire harness support body 100 includes the fixing member 2 formed in a cylindrical shape. Hereinafter, a case will be described in which the fixing member 2 is a reinforcement (instrument reinforcement) disposed on the back side of the instrument panel 82 of the vehicle 80 so as to extend in the width direction of the vehicle 80.

  Further, in the present embodiment, an example in which the wire harness support 100 includes the protection member 3 formed by the hollow plate material 30 including the plurality of plate-like portions 38 and the interposition portions 39 will be described.

<Protective member 3>
The wire harness support body 100 includes a protective member 3 that is a plate-like member that can be elastically deformed. In the present embodiment, as described above, the protection member 3 is formed by the hollow plate member 30 in which a hollow space is formed. First, the hollow plate 30 will be described.

  For example, the hollow plate 30 may be a member made of resin. Preferably, the hollow plate member 30 is a member that can be elastically deformed so as to bend.

  In the present embodiment, as shown in FIG. 3, the hollow plate member 30 is disposed between a plurality (here, two) of plate-like portions 38 and the plurality of plate-like portions 38. 38 and an intervening portion 39 that forms a hollow space.

  The material which forms the some plate-shaped part 38 and the interposition part 39 is not specifically limited. That is, the plurality of plate-like portions 38 and the intervening portions 39 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 38 and the intervening portion 39 is formed of paper, it is preferable to perform a water repellent treatment or the like on the surface.

  The plate-like portion 38 is formed in a flat plate shape. A plurality of plate-like portions 38 are connected via an intervening portion 39 with a space therebetween.

  Here, a plurality of intervening portions 39 are provided between the plurality of plate-like portions 38 in a parallel state with a space therebetween.

  Each interposed portion 39 is formed in an elongated plate shape, and is connected to the plate-like portion 38 in a posture orthogonal to the plate-like portions 38 on both sides.

  For this reason, when the hollow plate 30 is cut along a plane orthogonal to the extending direction of the interposition portion 39, a ladder-like cross section in which a plurality of interposition portions 39 exist in parallel between the pair of plate-like portions 38 is shown. .

  Such a hollow plate 30 can be continuously manufactured by, for example, an extrusion molding apparatus that extrudes a resin from an extrusion hole corresponding to a ladder-like cross section, whereby the plate is easily manufactured at low cost. Can do. Alternatively, the hollow plate 30 can also be manufactured by joining two plate-like portions 38 to both sides of a plurality of interposition portions 39 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 formed of resin are sometimes called plastic corrugated cardboard.

  By forming the protection member 3 using the hollow plate 30 as a material, the following advantages can be obtained. That is, the hollow plate 30 has a plurality of intervening portions 39 arranged in parallel with a gap, so that it is difficult to bend along the extending direction of the intervening portion 39, but is easy to bend along the parallel direction of the intervening portion 39. . At this time, the hollow plate member 30 is provided with a slit along the extending direction of the interposition portion 39 in the portion of the one plate-like portion 38 sandwiching the interposition portion 39 that is not in contact with the interposition portion 39, so that the other plate The portion facing the slit in the shaped portion 38 is further bent and becomes easier to bend. Further, the strength of the hollow plate 30 is excellent due to the structure forming the hollow structure. Furthermore, since the hollow plate 30 has a hollow structure, it is relatively lightweight for its strength. Further, the material used for the hollow plate 30 is also small for the strength. For this reason, material cost can be held down.

  And the protection member 3 formed with the hollow board | plate material 30 contains the plate-shaped main-body part 31 which can arrange | position an electric wire in the one surface side. Further, here, the protection member 3 includes a first insertion portion 321 and a second insertion portion 331. The protection member 3 can be obtained, for example, by cutting one hollow plate 30.

  The plate-shaped main body 31 is a portion where electric wires included in the wire harness 101 described later are disposed. In the wire harness 101, the plate-like main body 31 is interposed between the electric wire included in the wire harness 101 and the fixing member 2.

  Moreover, the protection member 3 is a member which can be bent here. Here, the protection member 3 is formed by folding a single plate-like main body portion 31 into a polygonal shape in sectional view. When the hollow plate member 30 is used as the material of the protection member 3, the protection member 3 can be easily bent when the extending direction of the interposition part 39 coincides with the extending direction of the fixing member 2.

  In this embodiment, the plate-shaped main body 31 is formed in a substantially rectangular shape. Below, the dimension of the longitudinal direction in the plate-shaped main-body part 31 is called a length dimension, and the dimension in a transversal direction is called a width dimension, and is demonstrated. In the wire harness support 100, the longitudinal direction coincides with the longitudinal direction of the protection member 3 and is a direction along the extending direction of the fixing member 2. Further, the short direction is a direction that coincides with the width direction of the protection member 3 and that follows the circumferential direction of the fixing member 2.

  More specifically, here, the plate-like main body 31 is bent along a fold line 34 extending along the longitudinal direction of the plate-like main body 31. Here, four folds 34 are provided at intervals along the width direction of the plate-like main body 31. Here, the both ends in the width direction of the plate-shaped main body 31 and the portions located outside the four folds 34 are referred to as a first end 32 and a second end 33, respectively. The plate-shaped main body 31 is folded in a mountain fold along the respective folds 34 so that the first end 32 and the second end 33 overlap with each other, so that the protection member 3 has a rectangular shape in a cross-sectional view. I am doing. Here, by providing the four folds 34 at equal intervals, the protective member 3 has a square shape in a cross-sectional view. At this time, the outermost fold line 34 is provided at a distance smaller than the distance between the adjacent fold lines 34 from the edge of the plate-like main body part 31 by the thickness of the plate-like main body part 31. The end portion 32 and the second end portion 33 can overlap over substantially the entire region.

  The width dimension in the plate-shaped main body 31 is determined by, for example, the circumferential length of the fixing member 2, the cross-sectional shape of the protection member 3, and the width dimension of the portion where the first end portion 32 and the second end portion 33 overlap. For example, when the cross-sectional shape of the protection member 3 and the width dimension of the portion where the first end portion 32 and the second end portion 33 overlap are the same, the width of the plate-like main body portion 31 decreases as the peripheral length of the fixing member 2 decreases. The dimensions can also be reduced. Further, for example, when the peripheral length of the fixing member 2 and the width dimension of the portion where the first end portion 32 and the second end portion 33 overlap are the same, the cross-sectional shape of the protection member 3 is made circular with more corners. The closer it is, the smaller the width of the plate-like main body 31 can be made. In addition, when the circumferential length of the fixing member 2 and the cross-sectional shape of the protection member 3 are the same, the smaller the width dimension of the portion where the first end portion 32 and the second end portion 33 overlap, The width dimension can be reduced.

  But about the width dimension of the part which the 1st end part 32 and the 2nd end part 33 overlap, the 1st end part 32 and the 2nd end part 33 can latch more reliably, so that it is large. For this reason, from the standpoint of locking reliability, the width dimension of the portion where the first end portion 32 and the second end portion 33 overlap is preferably set as large as possible. For example, the width dimension of the portion where the first end portion 32 and the second end portion 33 overlap is the same as the length of the longest side in the cross-sectional shape of the protective member 3 when the cross-sectional shape of the protective member 3 is a polygonal shape. More specifically, it is conceivable that the length of the longest side in the cross-sectional shape of the protection member 3 is set to be smaller by the thickness of the plate-like main body 31.

  Moreover, the length dimension in the plate-shaped main-body part 31 is a dimension which can cover the whole in the extending direction of the fixing member 2, when it is a dimension which can cover a part in the extending direction of the fixing member 2. It is conceivable that

  The width dimension of the first end portion 32 is the same as the width dimension of the other surface when folded into a square shape (here, a plate for overlapping the first end portion 32 and the second end portion 33) The thickness of the main body 31 is small).

  The first insertion portion 321 is provided at the first end portion 32 in the width direction of the plate-like main body portion 31. The first insertion portion 321 is formed with a first slit 322 extending from the edge portion of the first end portion 32 toward the second end portion 33 on the side opposite to the first end portion 32. Here, the peripheral edge portion of the first slit 322 in the first end portion 32 is the first insertion portion 321.

  The first slit 322 is formed so as to extend in parallel with the width direction of the plate-like main body portion 31 from the edge portion of the first end portion 32. A plurality of (here, two) first slits 322 are formed at intervals in the longitudinal direction of the protective member 3. The length dimension of the first slit 322 is set to about half the width dimension of the first end portion 32. The width dimension of the first slit 322 is preferably as small as possible within a range in which the second end 33 can be inserted into the first slit 322. Such a first slit 322 can be formed, for example, by making a cut in a part of the plate-like main body 31 or by cutting a part of the plate-like main body 31. In the longitudinal direction of the protection member 3, the position where the first slit 322 is provided is appropriately set depending on the length of the protection member 3, the number of the first slits 322, and the like.

  The width dimension of the second end portion 33 is the same as the width dimension of the other surface when folded into a square shape (here, a plate for overlapping the first end portion 32 and the second end portion 33) The thickness of the main body 31 is small).

  The second insertion portion 331 is provided at the second end portion 33 in the width direction of the plate-like main body portion 31. The second insertion portion 331 is formed with a second slit 332 extending from the edge of the second end portion 33 toward the first end portion 32. Here, the peripheral portion of the second slit 332 in the second end portion 33 is the second insertion portion 331.

  The second slit 332 is formed so as to extend in parallel with the width direction of the plate-like main body portion 31 from the edge portion of the second end portion 33. The length dimension of the second slit 332 is set to about half the width dimension of the second end 33. The width dimension of the second slit 332 is preferably as small as possible within a range in which the first end 32 can be inserted into the second slit 332. Such a second slit 332 can be formed, for example, by making a cut in a part of the plate-like main body 31 or by cutting a part of the plate-like main body 31.

  More specifically, here, the second slit 332 is formed at the same position as the first slit 322 along the longitudinal direction of the protective member 3. Here, the length dimension of the second slit 332 is set to be the same as the length dimension of the first slit 322.

  Here, since the first slit 322 and the second slit 332 are formed at the same position along the longitudinal direction of the protection member 3, the first slit 322 inserted into the second slit 332 of the first end portion 32 is used. The 1 insertion part 323 is a part located in the 1st edge part 32 on the opposite side to the edge part of the 1st edge part 32 along the width direction rather than the 1st insertion part 321. FIG. Similarly, the 2nd insertion part 333 inserted in the 1st slit 322 among the 2nd end parts 33 is the 2nd end along the width direction rather than the 2nd inserted part 331 among the 2nd end parts 33. This is a portion located on the opposite side of the edge of the portion 33.

  In addition, as described above, the width dimension of the first end portion 32 and the width dimension of the second end portion 33 are set to be the same, and the length dimension of the first slit 322 and the length of the second slit 332 are set. The dimension is set to about half the width dimension of the first end portion 32 and the second end portion 33, respectively. In addition to this, since the first slit 322 and the second slit 332 are formed at the same position along the longitudinal direction of the protection member 3, the first end portion 32 and the second end portion 33 are here. And overlap almost the whole area.

  It is preferable that at least one of the first end portion 32 and the second end portion 33 of the protection member 3 is formed to be elastically deformable in the thickness direction. Here, since the first end portion 32 and the second end portion 33 are part of one plate-like main body portion 31 made of the hollow plate material 30, the first end portion 32 and the second end portion 33 are: Both are formed to be elastically deformable in the thickness direction. Thereby, the 1st end part 32 and the 2nd end part 33 can be locked using elastic deformation. The locking between the first end portion 32 and the second end portion 33 will be described later in detail.

<Fixing member 2>
The wire harness support 100 includes a rod-shaped fixing member 2. Here, the fixing member 2 includes a rod-shaped main body portion 21 formed in a rod shape. In addition, in this embodiment, the wire harness support body 100 is provided with the cylindrical fixing member 2.

  As described above, the present embodiment is a case where the fixing member 2 is an instrument panel reinforcement.

  As shown in FIG. 1, the fixing member 2 is disposed on the back side of the instrument panel 82 of the vehicle 80 (the side opposite to the passenger compartment side) so as to extend in the width direction of the vehicle 80. The fixing member 2 is formed in a long shape. More specifically, as shown in FIG. 5, the rod-like main body portion 21 of the fixing member 2 is formed in a long cylindrical shape.

  The fixing member 2 may be provided with a bracket or the like. More specifically, the bracket may be attached to the outer surface of the rod-shaped main body portion 21 by welding or the like. The bracket is used for attaching the fixing member 2 to the vehicle 80 or attaching the electric wire to the fixing member 2.

<Wire harness support 100>
In the wire harness support body 100, the protection member 3 is attached to the fixing member 2 by making the protection member 3 cylindrical so as to surround the periphery of the fixing member 2.

  Specifically, in a state where the first end portion 32 and the second end portion 33 of the protection member 3 overlap each other, the protection member 3 surrounds the periphery of the fixing member 2 and is formed into a cylindrical shape. The protection member 3 maintains the cylindrical shape by inserting the second end portion 33. At this time, the first end 32 is inserted into the second slit 332 to assist the protection member 3 in maintaining a cylindrical shape.

  That is, here, the first end portion 32 and the second end portion 33 are reversed up and down across the first slit 322 and the second slit 332, so that the protection member 3 maintains a cylindrical shape. Here, the fact that the first end portion 32 and the second end portion 33 are turned upside down means that the end portions 32 and 33 appearing on the surface of the protective member 3 are different on both sides of the slits 322 and 332. .

  Here, the top and bottom of the end portions 32 and 33 are reversed in order along the longitudinal direction of the protection member 3 every time there are slits 322 and 332. More specifically, here, as described above, two first slits 322 and two second slits 332 are provided at the same position along the longitudinal direction of the protective member. One end portion (here, the first end portion 32) appears on the surface of the protective member 3 outside the first slit 322 and the second slit 332, that is, on both ends in the longitudinal direction of the protective member 3. The other end portion (here, the second end portion 33) appears on the surface of the protective member 3 at the portion sandwiched between the first slits 322 and the portion sandwiched between the two second slits 332.

  Thus, it can be considered that the wire harness support body 100 is completed because the protective member 3 can maintain the cylindrical shape surrounding the fixing member 2. That is, since the protective member 3 surrounds the fixed member 2 and is maintained in a cylindrical shape, the protective member 3 can be prevented from falling from the fixed member 2. At this time, it is preferable that the size of the protection member 3 is set so that the four inner surfaces of the protection member 3 having a square shape in cross section are in contact with the fixing member 2. As a result, the static friction between the protective member 3 and the fixing member 2 increases, so that the protective member 3 is less likely to be displaced along the extending direction of the fixing member 2, and the protective member 3 fixes the fixing member 2. It becomes difficult to rotate as an axis.

  Here, the first end portion 32 and the second end portion 33 will be described as being overlapped vertically below the fixing member 2, but this is not essential. For example, a case where the first end portion 32 and the second end portion 33 overlap with the fixing member 2 in the vertical direction may be considered. For example, the case where the 1st end part 32 and the 2nd end part 33 have overlapped with the fixing member 2 in the horizontal direction side is also considered.

  When the protection member 3 is maintained in a cylindrical shape, the first end portion 32 and the second end portion 33 are locked using elastic deformation of the first end portion 32 and the second end portion 33. Thereby, the protection member 3 can maintain a cylindrical shape more reliably.

  Here, the portion including the edge portion of the first end portion 32, more specifically, the first end portion 32 than a line passing through the tip of the first slit 322 and parallel to the longitudinal direction of the first end portion 32. The portion on the edge portion side is referred to as a first locking portion 324. Similarly, the portion of the second end portion 33 including the edge portion, more specifically, the second end portion 33 rather than a line passing through the tip of the second slit 332 and parallel to the longitudinal direction of the second end portion 33. A portion on the end edge side is referred to as a second locking portion 334.

  The second end 33 is inserted into the first slit 322 and the first end 32 is inserted into the second slit 332, and the end of the second end 33 of the first end 32. A portion located between the edge portion and a line passing through the tip of the second slit 332 and parallel to the longitudinal direction of the second end portion 33 is referred to as a first locked portion 325. Similarly, in the state where the second end 33 is inserted into the first slit 322 and the first end 32 is inserted into the second slit 332, of the second end 33, A portion located between the end edge portion and a line passing through the tip of the first slit 322 and parallel to the longitudinal direction of the first end portion 32 is referred to as a second locked portion 335. The first locked portion 325 includes a portion that overlaps with the second locking portion 334. Similarly, the second locked portion 335 includes a portion that overlaps the first locking portion 324.

  In addition, when the 1st slit 322 and the 2nd slit 332 are formed in a different position along the longitudinal direction of the protection member 3, the 1st latching | locking part 324 and the 1st to-be-latched part among the 1st edge parts 32 are shown. 325 corresponds to the same portion, and similarly, the second locking portion 334 and the second locked portion 335 of the second end portion 33 correspond to the same portion. Here, since the 1st slit 322 and the 2nd slit 332 are formed in the same position along the longitudinal direction of the protection member 3, the 1st latching | locking part 324 and the 1st engagement part among the 1st edge parts 32 are used. Similarly, the second locking portion 334 is different from the second locking portion 335 in the second end portion 33.

  When the second end 33 is inserted into the first slit 322 and the first end 32 is inserted into the second slit 332, the first end 32 and the second end 33 are elastic as follows. Deform. That is, both side portions of the first locking portion 324 sandwiching the first slit 322 along the longitudinal direction of the protection member 3 are elastically deformed so as to be separated in the thickness direction. Similarly, both side portions of the second locking portion 334 sandwiching the second slit 332 along the longitudinal direction of the protective member 3 are elastically deformed so as to be separated in the thickness direction. Thereby, the restoring force of the elastic deformation of the both side parts which pinched | interposed the 1st slit 322 along the longitudinal direction of the protection member 3 among the 1st latching | locking parts 324 acts as a force which clamps the 2nd to-be-latched part 335. . In particular, both side edge portions of the first insertion portion 321 strongly sandwich the second insertion portion 333. Similarly, the restoring force of elastic deformation of both side portions of the second locking portion 334 sandwiching the second slit 332 along the longitudinal direction of the protection member 3 acts as a force for sandwiching the first locked portion 325. . In particular, both side edge portions of the second insertion portion 331 strongly sandwich the first insertion portion 323.

  At this time, both side portions of the second insertion portion 333 are elastically deformed so as to bend in the thickness direction along the longitudinal direction of the protection member 3 in the second locked portion 335. Similarly, both the side parts of the 1st insertion part 323 are elastically deformed so that it may bend in the thickness direction along the longitudinal direction of the protection member 3 among the 1st to-be-latched parts 325. FIG. These elastic deformation restoring forces also act to make the first end 32 and the second end 33 more firmly locked.

  As described above, when the second insertion portion 333 is inserted into the first slit 322 and the first insertion portion 323 is inserted into the second slit 332, the first end portion 32 and the second insertion portion 333 are inserted. Each part of the end portion 33 is elastically deformed, the first locking portion 324 and the second locked portion 335 are pressed against each other, and the second locking portion 334 and the first locked portion 325 are pressed against each other. Hold on. As a result, the second insertion portion 333 is inserted into the first slit 322 and the first insertion portion 323 is inserted into the second slit 332, and the first end portion 32, the second end portion 33, and the like. Is difficult to separate, and the first end portion 32 and the second end portion 33 are locked. As described above, since the first end portion 32 and the second end portion 33 can be elastically deformed, the state in which the protection member 3 surrounds the fixing member 2 and has a cylindrical shape can be more reliably maintained.

<Wire harness 101>
Next, the wire harness 101 provided with the wire harness support body 100 and an electric wire is demonstrated, referring FIG. FIG. 6 is an upper perspective view showing the wire harness support 100 and the wire harness 101 including the same according to the embodiment.

  This embodiment demonstrates the case where the wire harness 101 is provided with the electric wire bundle 9 containing a some electric wire. In FIG. 6, the wire bundle 9 is shown in a simplified manner.

  In the wire harness 101, it is conceivable that the electric wires included in the electric wire bundle 9 are, for example, insulated wires including a core wire and an insulating coating covering the periphery of the core wire. For example, the core wire may be a member mainly composed of a metal such as copper or aluminum. The insulating coating may be a synthetic resin member mainly composed of polyethylene or vinyl chloride, for example.

  Moreover, in the example shown by FIG. 6, the case where the wire bundle 9 is fixed to the fixing member 2 by the clamp 99 is shown. The clamp 99 includes, for example, a belt portion wound around the wire bundle 9 and a clip portion that fixes the belt portion to the fixing member 2. Therefore, it is conceivable that the fixing member 2 has a clamp fixing hole for fixing the clamp 99. In FIG. 6, the clamp 99 is indicated by a virtual line (two-dot chain line). But the electric wire bundle 9 may be fixed by other fixing members, such as an adhesive tape. Further, the wire bundle 9 may be fixed to the protection member 3.

  In the wire harness 101, an electric wire bundle 9 including a plurality of electric wires is disposed on the plate-like main body portion 31 of the protection member 3. As a result, the plate-shaped main body 31 is interposed between the wire bundle 9 and the fixing member 2, so that the wires included in the wire bundle 9 are prevented from coming into contact with the fixing member 2. For this reason, it can suppress that an electric wire contacts the edge part produced by the burr | flash etc. in the fixing member 2, and is damaged.

  At this time, the wire bundle 9 is preferably disposed on a surface of the protection member 3 other than the surface where the first end portion 32 and the second end portion 33 overlap. Here, the wire bundle 9 is disposed on the surface of the protection member 3 that is located on the opposite side to the surface on which the first end portion 32 and the second end portion 33 overlap. Thereby, it can suppress that an electric wire contacts the edge part of the protection member 3, and is damaged. But the wire bundle 9 may be arrange | positioned in the surface where the 1st end part 32 and the 2nd end part 33 overlap among the protection members 3. FIG.

  Moreover, in the example shown by FIG. 6, the case where the protection member 3 covers the one part area | region in the extension direction of the fixing member 2 is shown. However, it is conceivable that the protection member 3 covers the entire region in the extending direction of the fixing member 2, that is, the protection member 3 is provided over the entire length of the fixing member 2. In addition, a plurality of protective members 3 covering a part of the region in the extending direction of the fixing member 2 may be arranged in the extending direction of the fixing member 2. In this case, the protection member 3 including the plate-like main body 31 can be disposed only in the portion that requires protection of the electric wire.

  According to the wire harness support body 100 and the wire harness 101 according to the embodiment, the protection member 3 surrounds the fixed member 2 in a cylindrical shape in a manner in which the first end portion 32 and the second end portion 33 overlap each other. Thus, the protection member 3 maintains a cylindrical shape by the second end 33 being inserted into the first slit 322. That is, the first end portion 32 and the second end portion 33 are turned upside down across the first slit 322 (the end portions appearing on the surface of the protection member 3 are different on both sides of the slit), thereby protecting the protective member 3. However, since the cylindrical shape is maintained, the protection member 3 and the rod-shaped fixing member 2 can be fixed with a simpler configuration.

  In addition, since the plurality of first slits 322 are formed at intervals in the longitudinal direction of the protective member 3, the number of times that the first end portion 32 and the second end portion 33 are reversed upside down increases. Thereby, when the protection member 3 is formed into a cylindrical shape around the fixing member 2, the cylindrical shape can be more reliably maintained.

  Further, the protection member 3 is provided at the second end portion 33, and a second insertion portion 331 in which a second slit 332 extending from the end edge portion of the second end portion 33 toward the first end portion 32 is formed. Since the first end portion 32 is inserted into the second slit 332, the first end portion 32 and the second end portion 33 are difficult to separate. Thereby, when the protection member 3 is formed into a cylindrical shape around the fixing member 2, the cylindrical shape can be more reliably maintained.

  Moreover, since the 1st slit 322 and the 2nd slit 332 are formed in the same position along the longitudinal direction of the protection member 3, while the 1st to-be-inserted part 321 and the 2nd to-be-latched part 335 mesh, Since the second inserted portion 331 and the first locked portion 325 are engaged with each other, the first end portion 32 and the second end portion 33 are less likely to be displaced in the longitudinal direction of the protection member 3. Thereby, when the protection member 3 is formed into a cylindrical shape around the fixing member 2, the cylindrical shape can be more reliably maintained. In addition, the area of the overlapping portion can be increased while shortening the length of one slit.

  Moreover, since the protection member 3 is formed by folding the single plate-like main body portion 31 into a polygonal shape in cross section, the number of parts can be reduced.

  Further, the protection member 3 includes a hollow plate member 30 including a plurality of plate-like portions 38 and an interposition portion 39 that is disposed between the plurality of plate-like portions 38 and forms a hollow space between the plurality of plate-like portions 38. Therefore, the protective member 3 can be made relatively lightweight for its strength. Moreover, material cost can be suppressed by being able to hold down the material used for the hollow plate material 30 to a small extent for strength.

  Moreover, the number of clamps for fixing the protective member 3 and the fixing member 2 can be reduced, and the number of parts constituting the wire harness 101 can be reduced.

{Modifications}
In the embodiment, the second slit 332 is provided at the second end 33, but the second slit 332 may not be provided at the second end 33. That is, the first end 32 and the second end 33 may be locked only by the first slit 322.

  Even when the second slit 332 is provided at the second end 33, the first slit 322 and the second slit 332 are formed at the same position along the longitudinal direction of the protective member 3. Not required. That is, the first slit and the second slit may be formed at different positions along the longitudinal direction of the protective member 3. In this case, by inserting the second end portion 33 into the first slit and inserting the first end portion 32 into the second slit, the number of times that the first end portion 32 and the second end portion 33 are turned upside down increases. Therefore, the first end portion 32 and the second end portion 33 can be more reliably locked. In addition, when the 1st slit and the 2nd slit are formed in a different position along the longitudinal direction of the protection member 3, it is preferable that the length of a 1st slit and the length of a 2nd slit are the same.

  Further, the second slit 332 is provided at the second end 33, and the first slit 322 and the second slit 332 are formed at the same position along the longitudinal direction of the protection member 3. However, it is not essential that the first slit 322 and the second slit 332 are set to the same length. The first slit and the second slit may be set to different lengths. In this case, as long as the sum of the length of the first slit and the length of the second slit does not exceed the shorter width dimension of the first end portion 32 and the second end portion 33, the sum is equal to the first end portion 32. And the width dimension of the portion where the second end 33 overlaps.

  In the embodiment, the first end portion 32 and the second end portion 33 have been described as being locked using elastic deformation, but this is not essential. The first end and the second end are formed in a shape that can be inserted without elastic deformation, and the second end is simply inserted into the first slit, and the first end is inserted into the second slit. The cylindrical shape may be maintained by having been inserted. In this case, the larger the amount to be inserted, that is, the longer the first slit and the second slit, the more difficult the first end and the second end are separated.

  In the embodiment, the protection member 3 is described as a member that can be bent, but this is not essential. For example, the protection member 3 may be combined so that the side walls of the two members formed in the shape of a cross-sectional view are overlapped.

  Even when the protective member 3 is a foldable member, it is not essential that the protective member 3 is formed by bending the single plate-like main body portion 31. For example, a case where the above-described member having a bowl-like shape in cross-section is formed by bending the two plate-like main body portions 31 respectively.

  In addition, when there is a difference in rigidity between the first end portion 32 and the second end portion 33 when, for example, two members are combined to form the protective member 3 as described above, the one with the larger rigidity is not elastically deformed. There may be cases.

  Moreover, it is not essential that the protection member 3 is formed in a quadrangular shape in cross-sectional view. For example, the protection member may be formed in a triangular shape in cross-sectional view or a polygonal shape that is a pentagon or higher in cross-sectional view. At this time, as the number of corners of the protective member increases, the protective member becomes easier to follow along the peripheral surface of the fixing member, and the width dimension of the plate-like main body portion can be reduced. As a result, the protective member can be reduced in weight and space.

  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.
