Description

[Technical field]

[0001] The present invention relates to a harness holding member that holds, for example, a wire harness and is attached to a predetermined location in a vehicle. [Background technology]

[0002] Wire harnesses that electrically connect various electrical devices installed in a vehicle are fixed to the vehicle using harness holding members and are routed in complex two- or three-dimensional routing paths that match the uneven shape of the vehicle.

[0003] As an example of such a harness holding member, Patent Document 1 discloses a harness holding member composed of a clip member having a connecting shaft portion having a regular hexagonal cross-section, a connecting hole having a regular hexagonal cross-section into which the connecting shaft portion can be inserted, and a band member having a band portion for winding the wire harness.

[0004] The harness holding member is configured such that the connecting shaft portion is inserted into the connecting hole at a desired angle, and then the band portion wound around the wire harness is inserted into a communication hole that communicates the connecting hole and the connecting shaft portion, and the clip member and the band portion are integrally connected to each other, so that the extension direction of the wire harness relative to the clip member can be set in a desired direction. This is said to be capable of suppressing interference between the wire harness and other members, such as electrical devices, arranged around the wiring path.

[0005] However, the harness holding member determines the extension direction of the wire harness by first connecting and integrating the clip member and the band member, and then fixing the clip member to a predetermined position, which causes a problem that it is difficult to change the extension direction of the wire harness after it is fixed to the vehicle.

[0006] [Patent Document 1] JP 2016-116371 A Summary of the Invention [Problem to be solved by the invention]

[0007] An object of the present invention is to provide a harness holding member that allows the extension direction of a wire harness to be easily changed even after the harness holding member is fixed to a vehicle. [Means for solving the problem]

[0008] The present invention is characterized in that it is a harness holding member comprising a harness holding portion that holds a wire harness, a fixed portion that is fixed to a vehicle, a connecting portion that connects the fixed portion and the harness holding portion to allow relative rotation, a rotation restriction mechanism that restricts rotation between the fixed portion and the harness holding portion in at least one direction, and a deregulation mechanism that relaxes the restriction of relative rotation between the fixed portion and the harness holding portion by the rotation restriction mechanism.

[0009] The wire harness includes, in addition to covered electric wires, communication cables such as optical fiber cables and bundles of these cables. The fixing portion is not particularly limited as long as it can be fixed to the vehicle, and includes, for example, an anchor that is inserted into an anchor hole provided in the vehicle, or a sliding structure that slides and fixes to a stay or clip provided at a predetermined location.

[0010] The connecting portion includes, for example, a configuration in which the fixing portion and the harness holding portion are connected by combining a portion of the fixing portion and the harness holding portion, as well as a configuration in which the fixing portion and the harness holding portion are connected via another member.

[0011] The deregulation mechanism includes a configuration for relaxing the restriction by the rotation restriction mechanism so that the fixed portion and the harness holding portion can rotate relative to each other by applying a predetermined external force to at least one of the fixed portion and the harness holding portion, whose rotation is restricted by the rotation restriction mechanism, and a configuration for releasing the rotation restriction by the rotation restriction mechanism.

[0012] According to the present invention, the extending direction of the wire harness can be easily changed even after the wire harness is fixed to the vehicle. In more detail, by providing the rotation restriction mechanism, it is possible to restrict the rotation between the fixed part and the harness holding part, and therefore it is possible to restrict the extension direction of the wire harness relative to the fixed part. On the other hand, by providing the restriction relaxation mechanism, it is possible to relax the rotation restriction between the fixed part and the harness holding part by the rotation restriction mechanism by applying a predetermined external force in a state in which the rotation between the fixed part and the harness holding part is restricted. This allows the fixed part and the harness holding part to rotate relative to each other, and it is possible to change the extension direction of the wire harness restricted by the rotation restriction mechanism to a desired direction.

[0013] Furthermore, by reducing the applied specified external force, the rotation restriction mechanism can again restrict the rotation between the fixed portion and the harness holding portion, so that the extension direction of the wire harness can be fixed while the wire harness is changed to the desired extension direction.

[0014] In this way, by providing the rotation restriction mechanism and the restriction relaxation mechanism, the harness holding part, whose rotation is restricted with respect to the fixed part, can be rotated relatively to a desired angle, and the relative rotation between the fixed part and the harness holding part, which has been changed to the desired angle, can be restricted. Therefore, even after the fixed part is fixed to a predetermined position, the extension direction of the wire harness held by the harness holding part connected to the fixed part via the connecting part can be changed and the state can be maintained.

[0015] As an aspect of the invention, the connecting portion may have an extension portion provided on at least one of the fixed portion and the harness holding portion, extending from one of the fixed portion and the harness holding portion toward the other, and a accommodating portion provided on the other of the fixed portion and the harness holding portion, accommodating at least a portion of the extension portion.

[0016] According to this invention, the fixing part and the harness holding part can be connected with a simple structure that only requires accommodating the extension part in the accommodation part. In addition, since at least a part of the extension part is accommodated in the accommodation space of the accommodation part, even if an unintended external force acts on the connection part, the extension part can be prevented from falling off the accommodation part. Therefore, it is possible to prevent the connection between the fixing part and the harness holding part from being easily released.

[0017] In another aspect of the invention, a direction perpendicular to the rotational direction in which the fixing portion and the harness holding portion rotate relative to each other is defined as a radial direction, and one of the inner surface of the accommodating portion and the outer surface of the extension portion is provided with a plurality of locking teeth having locking surfaces facing in the radial direction, and the other of the inner surface and the outer surface is provided with locking portions that lock onto the locking surfaces, the locking teeth and the locking portions function as the rotation restriction mechanism, and the restriction relaxation mechanism may relax the locking of the locking portions to the locking surfaces.

[0018] The locking surface includes a surface along the radial direction and a surface intersecting the radial direction. The rotation restriction mechanism is not particularly limited as long as the locking surface and the locking portion can be locked with each other, for example, the locking surface formed between a plurality of locking teeth protruding toward one side in the radial direction is locked with a locking portion protruding toward the other side in the radial direction, or the locking portion recessed toward one side in the radial direction is locked with a locking surface formed on a locking tooth protruding toward one side in the radial direction.

[0019] According to this invention, the fixing part and the harness holding part can be reliably locked with a simple structure that only requires that the locking part be locked with the locking surface. Also, because the locking between the locking teeth and the locking part is performed within the accommodation space of the accommodation part, it is possible to prevent the rotation restriction by the locking between the locking surface and the locking part from being unintentionally released.

[0020] As a further aspect of the present invention, the locking portion may have an elastic support portion that elastically supports the locking portion so as to bias the locking portion against the locking surface in a rotational direction, and the elastic support portion may function as the restriction relaxation mechanism. According to this invention, the locking portion, which is elastically supported by the elastic support portion so as to be biased in the rotational direction, can be locked to the locking surface, so that the rotation of the fixed portion and the harness holding portion can be reliably restricted. On the other hand, when a predetermined external force is applied in the rotational direction, the elastic support portion is elastically deformed to release the locking between the locking surface and the locking portion, so that the fixed portion and the harness holding portion can rotate relative to each other.

[0021] In this way, since the locking portion has an elastic support portion that elastically supports the locking surface so as to urge the locking surface in the rotational direction, the elastic support portion elastically deforms and the locking surface and the locking portion can be released only when a predetermined external force is applied. Therefore, unintended rotation of the fixing portion and the harness holding portion can be restricted, and the extension direction of the wire harness can be changed by intentionally applying a predetermined external force to rotate the fixing portion and the harness holding portion relative to each other.

[0022] In another aspect of the invention, the direction perpendicular to the rotational direction in which the fixed portion and the harness holding portion rotate relative to each other is defined as the radial direction, the extension portion extends along the rotational axis of the relative rotation, a plurality of external teeth are provided on the outer surface of the extension portion along the rotational direction, and a plurality of internal teeth are provided on the inner surface of the accommodating portion along the rotational direction, the external teeth and the internal teeth engage radially to function as the rotation restricting mechanism, and the deregulation mechanism may relax the engagement between the external teeth and the internal teeth.

[0023] According to this invention, the external teeth and internal teeth provided along the rotational direction are fitted together, so that the relative rotation between the fixed portion and the harness holding portion can be reliably restricted. The number of the external teeth and the number of the internal teeth may be the same or different. In other words, this includes a case where the internal teeth are fitted to the multiple external teeth over the entire circumference in the rotational direction, as well as a case where the internal teeth are fitted to only a portion of the multiple external teeth.

[0024] In another aspect of the present invention, the accommodating portion has an internal tooth forming portion with the internal teeth provided on the inner surface, and the internal tooth forming portion is configured to deform radially outwardly under a predetermined load, and the internal tooth forming portion that deforms radially outwardly under a predetermined load may function as the deregulation mechanism.

[0025] The above-mentioned "deformation toward the outside in the radial direction" includes a case where a part or all of the internal teeth-forming portion is deformed. Specifically, it includes a case where a part or all of the internal teeth-forming portion including the internal teeth moves toward the outside in the radial direction so that the restriction on the relative rotation between the fixing portion and the harness holding portion is relaxed, or a case where a shape of a part of the internal teeth-forming portion is deformed.

[0026] According to this invention, unintended rotation of the fixing portion and the harness holding portion can be restricted, and the extending direction of the wire harness can be easily changed by applying a predetermined load to the internal teeth forming portion. In more detail, in a state in which the relative rotation between the fixed part and the harness holding part is restricted by the internal teeth and external teeth that are fitted together in the radial direction, by increasing the rotational force acting in a direction that rotates the fixed part and the harness holding part relative to each other, the applied rotational force is converted into a deformation force that deforms the internal teeth-forming part radially outward, thereby deforming the internal teeth-forming part radially outward, relaxing the fit between the internal teeth and external teeth and allowing the fixed part and the harness holding part to rotate relative to each other.

[0027] In this way, since the internal teeth forming portion is configured to deform radially outward under a predetermined load, the internal teeth forming portion can be deformed radially outward to relax the engagement between the internal teeth and the external teeth only when a rotational force equal to or greater than a predetermined value is applied. This allows the fixing portion and the harness holding portion to rotate relative to each other. Therefore, unintended rotation of the fixing portion and the harness holding portion can be restricted, and the extension direction of the wire harness can be changed.

[0028] As a further aspect of the present invention, the accommodating portion may be provided with slits that divide the internal teeth forming portion into a plurality of portions along the rotational direction. According to this invention, since the internal teeth forming portion can be divided into a plurality of portions by the slits, it is possible to reduce the influence of other factors on the deformation of each of the divided internal teeth forming portions. In other words, the deformability of the divided internal teeth forming portion can be improved, and therefore the engagement between the internal teeth and the external teeth can be more reliably relaxed.

[0029] As another aspect of the present invention, the internal teeth forming portion may be formed in a polygonal shape when viewed from a direction along the rotation axis, and the slit may be formed so as to pass through a vertex of the polygonal internal teeth forming portion.

[0030] According to this invention, the internal teeth forming portion can be divided so as not to include the apex portion. In other words, in the radially outward deformation of the internal teeth forming portion, the deformability of each divided portion of the internal teeth forming portion can be improved compared to the case where the internal teeth forming portion is divided so as to include the apex portion, so that the locking between the internal teeth and the external teeth can be relaxed with a smaller rotational force. Therefore, the fixing portion and the harness holding portion can be easily rotated relative to each other.

[0031] As a further aspect of the present invention, the internal teeth forming portion may be made of an elastic body that is elastically deformed by a predetermined load. According to this invention, since the internal teeth forming portion is configured to be elastically deformed toward the outside in the radial direction by a predetermined load, the internal teeth forming portion is elastically deformed toward the outside in the radial direction only when a rotational force equal to or greater than a predetermined value is applied, and the engagement between the internal teeth and the external teeth can be relaxed. This allows the fixing portion and the harness holding portion to rotate relative to each other. Therefore, unintended rotation of the fixing portion and the harness holding portion can be restricted, and the extension direction of the wire harness can be changed.

[0032] As a further aspect of the present invention, a deformation restricting portion may be provided that restricts deformation of the internal teeth forming portion in the radial direction. The deformation restricting portion is not particularly limited as long as it can restrict the radial deformation of the internal teeth forming portion, and includes, for example, a configuration in which the deformation restricting portion restricts the radial outward deformation by surrounding the entire circumference of the internal teeth forming portion or by fixing the adjacent internal teeth forming portions. Note that the deformation restricting portion may be integrally formed with the internal teeth forming portion or may be formed as a separate member that can be attached to the internal teeth forming portion.

[0033] According to the present invention, the radial outward movement of the internal teeth forming portion can be restricted, and therefore the relative rotation between the fixing portion and the harness holding portion can be reliably restricted. In other words, after the extension direction of the wire harness is changed, the fixing portion and the harness holding portion can be prevented from rotating relative to each other, which can prevent the extension direction of the wire harness from being further changed.

[0034] As a further aspect of the present invention, the deregulation mechanism may deregulate the restriction on relative rotation in both directions between the fixing portion and the harness holding portion. According to the present invention, since the fixing portion and the harness holding portion can be rotated relative to each other in both directions along the rotation direction, the relative angle between the fixing portion and the harness holding portion can be adjusted more easily, thereby improving the workability of changing the extension direction of the wire harness.

[0035] As a further aspect of the present invention, the deregulation mechanism may deregulate the restriction on relative rotation in one direction between the fixing portion and the harness holding portion. According to this invention, the relative rotation between the fixing portion and the harness holding portion is only possible in one direction along the rotation direction, so that unintentional rotation in the other direction can be prevented.

[0036] In another aspect of the invention, the direction perpendicular to the rotational direction in which the fixing portion and the harness holding portion rotate relative to each other is defined as the radial direction, the extension portions are provided in multiple locations at a predetermined interval in the radial direction and are configured to be elastically deformable along the radial direction, a plurality of engageable portions having engageable surfaces facing the radial direction are provided on the inner surface of the accommodating portion, and engageable portions that engage with the engageable surfaces are provided on the outer surface of the extension portions, the engageable portions and the engageable portions function as the rotation restricting mechanism, and elastic deformation of the extension portions along the radial direction functions as the deregulation mechanism.

[0037] According to this invention, the engagement between the locking portion and the locked portion can be released by elastically deforming the multiple extending portions toward one radial side. This allows the fixed portion and the harness holding portion to rotate relatively easily. Meanwhile, since the extending portions are configured to be elastically deformable in the radial direction, a restoring force acts on the extending portions when the elastic deformation of the extending portions is released. This allows the extending portions to be restored toward the other radial side, and the locking portion and the locked portion can be engaged. Therefore, the relative rotation between the fixed portion and the harness holding portion that have been rotated to a desired extension direction can be restricted. Effect of the Invention

[0038] According to the present invention, it is possible to provide a harness holding member that allows the extending direction of the wire harness to be easily changed even after the harness holding member is fixed to a predetermined location in a vehicle. [Brief description of the drawings]

[0044] Here, the direction in which the wire harness WH in Fig. 1 extends is the longitudinal direction L, and the direction perpendicular to the longitudinal direction L and along the top and bottom is the height direction H. The direction perpendicular to the longitudinal direction L and the height direction H is the width direction W. The left side along the longitudinal direction L is the front side La, and the right side is the rear side Lb. The lower side along the height direction H is the lower side Hd, and the upper side is the upper side Hu. The left side along the width direction W is the left side Wl, and the right side is the right side Wr.

[0045] 1, the harness holding member 1 holds a wire harness WH electrically connected to electric devices, and fixes the wire harness WH to a body panel P of a vehicle by inserting it into and fixing it in an anchor insertion hole P1 provided in the body panel P. Here, the anchor insertion hole P1 provided in the body panel P is formed in a substantially elliptical shape in a plan view.

[0046] The harness holding member 1 having the above-mentioned functions is composed of a connecting and fixing part 2 that can be engaged and fixed to a body panel P of a vehicle, and a holding and connecting part 3 that holds a wire harness WH, as shown in Figures 1 to 3. Here, the wire harness WH is a bundle of covered electric wires, each of which has a conductor covered with an insulating coating. However, the wire harness WH is not limited to this, and may be, for example, a bundle of communication cables such as optical fiber cables, or a bundle of covered electric wires and communication cables.

[0047] As shown in Figures 2 and 3, the connecting and fixing part 2 is integrally composed of an anchor part 10 that is inserted into and fixed to an anchor insertion hole P1 provided in the body panel P, and an extension part 20 that extends from the end of the upper side Hu of the anchor part 10.

[0048] The anchor portion 10 is a so-called anchor that can be engaged and fixed to the body panel P by being inserted into the anchor insertion hole P1, and as shown in Figures 2, 3 and 4(a), has a columnar insertion shaft portion 11 extending along the height direction H, a pair of engagement projections 12 protruding from the lower end of the insertion shaft portion 11 in the longitudinal direction L, and an umbrella-shaped umbrella portion 13 provided at the upper end of the insertion shaft portion 11. The insertion shaft portion 11 is a columnar body extending along the height direction H. The cross-sectional shape of this insertion shaft portion 11 is a substantially elliptical shape that is substantially the same shape as the anchor insertion hole P1.

[0049] The pair of locking projections 12 project from the lower end of the insertion shaft 11 in the height direction H and both end portions in the longitudinal direction L so as to move away from the insertion shaft 11 as they move toward the upper side Hu. The tip portions of the locking projections 12 are curved inward in the longitudinal direction L so as to approach the insertion shaft 11 as they move toward the upper side Hu. The end of the upper side Hu of the locking projections 12 curved in this manner is provided with an abutment surface portion 12a that abuts against the back surface of the body panel P when the anchor portion 10 is inserted into the anchor insertion hole P1.

[0050] The umbrella portion 13 is a flexible umbrella-shaped body that has a major axis along the longitudinal direction L and a minor axis along the width direction W in a plan view and curves downward Hd as it moves away from the insertion shaft portion 11. The outer edge portion of the umbrella portion 13 is disposed outside the locking projection 12 in the longitudinal direction L.

[0051] As shown in Figures 2 and 4, the extension portion 20 is integrally formed of a cylindrical external tooth forming portion 21 extending from the anchor portion 10 toward the upper side Hu, and a truncated cone-shaped anti-slip portion 22 provided on the upper side Hu of the external tooth forming portion 21.

[0052] The external teeth forming portion 21 is a substantially cylindrical body protruding toward the upper side Hu from the umbrella portion 13 provided at the upper end of the anchor portion 10. More specifically, the external teeth forming portion 21 is composed of a cylindrical main body 211 having a predetermined outer diameter, and a plurality of locking external teeth 23 protruding radially outward from the outer circumferential surface of the cylindrical main body 211, as shown in Figs.

[0053] Here, the direction perpendicular to the central axis of the cylindrical main body 211 is defined as the radial direction, and the direction along the outer periphery of the cylindrical main body 211 formed in a circular shape in plan view is defined as the circumferential direction. In addition, in plan view, the direction toward the center of the cylindrical main body 211 along the radial direction is defined as the radially inner side, and the direction away from the center of the cylindrical main body 211 is defined as the radially outer side. In addition, in bottom view, the clockwise direction along the circumferential direction is defined as one side in the circumferential direction, and the counterclockwise direction along the circumferential direction is defined as the other side in the circumferential direction.

[0054] 4(c), the locking external teeth 23 are approximately triangular prisms having an approximately triangular bottom surface that protrudes radially outward from the outer circumferential surface of the cylindrical main body 211 so as to be inclined to one circumferential side of the external teeth forming portion 21 when viewed from the bottom, and the height (length along the height direction H) of the locking external teeth 23 is equal to the height of the external teeth forming portion 21. The locking external teeth 23 have a predetermined rigidity.

[0055] That is, the external locking teeth 23 have two locking surfaces with different side lengths in bottom view. Here, the locking surface with the shorter length in bottom view is the inner locking surface 231, and the locking surface with the longer length is the outer locking surface 232. That is, the inner locking surface 231 is provided on the radially inner side, and the outer locking surface 232 is provided on the radially outer side. Note that, in plan view, the inner locking surface 231 and the outer locking surface 232 form an acute angle. A plurality of the thus configured external locking teeth 23 are provided at equal intervals along the circumferential direction of the columnar main body 211, as shown in FIG. 4(c).

[0056] The retaining portion 22 is a truncated cone tapered toward the upper side Hu, and is disposed at the end of the upper side Hu of the external teeth forming portion 21. More specifically, the retaining portion 22 is a truncated cone having a bottom surface with a radius longer than the length from the midpoint of the cylindrical body 211 to the apex of the external locking teeth 23, and having an upper surface with a radius equal to the length from the center of the cylindrical body 211 to the apex of the external locking teeth 23. The central axes of the external teeth forming portion 21 and the retaining portion 22 coincide with each other.

[0057] In this manner, the extension portion 20 in which the external teeth forming portion 21 and the retaining portion 22 are integrally arranged in parallel from the lower side Hd to the upper side Hu is formed in a substantially T-shape in a side view. Here, the bottom surface portion of the retaining portion 22 protruding from the outer edge of the external teeth forming portion 21 is defined as a retaining surface portion 221.

[0058] As shown in Figures 2 and 3, the holding connection portion 3 is integrally formed with a band fixing portion 30 that holds the wire harness WH and a storage portion 40 provided on the surface of the lower side Hd of the band fixing portion 30. As shown in Figures 2, 3 and 5, the band fixing portion 30 has a buckle portion 31 configured as a hollow, approximately rectangular parallelepiped, and a long band portion 32 extending from the end of the buckle portion 31 on the right side Wr.

[0059] As shown in Fig. 5(b), the buckle portion 31 is a hollow, substantially rectangular parallelepiped having a band insertion portion 311 penetrating the center portion in the height direction H from the left side Wl to the right side Wr. The band insertion portion 311 is provided with a locking piece 312 that protrudes from the lower side Hd to the upper side Hu as it moves from the left side Wl to the right side Wr. The end portion of the lower side Hd of the buckle portion 31 is partially cut out on the right side Wr, and the tip portion of the locking piece 312 is exposed.

[0060] The band portion 32 is a long strip extending from the end of the right side Wr of the buckle portion 31, and is configured so that the band insertion portion 311 can be inserted from the left side Wl to the right side Wr, and so that when inserted into the band insertion portion 311, it can engage with the locking piece 312.

[0061] 3 and 5, the storage section 40 has a generally rectangular parallelepiped shape that is connected to the surface of the lower side Hd of the buckle section 31, and is made of a resin having a predetermined rigidity. The storage section 40 has an opening on the bottom surface through which the extension section 20 is inserted, and has a storage space S capable of storing the extension section 20 therein.

[0062] More specifically, the storage section 40 has a generally rectangular parallelepiped shape that is one size smaller than the band fixing section 30, and as shown in Figures 5(a) and 6, has a support section 41 connected to the lower side Hd of the buckle section 31, and an internal teeth forming section 42 that can be deformed outward using the connection section with the support section 41 as a base. In addition, on the outside of the storage section 40, there is provided an annular restricting reinforcement member 43 that can move in the height direction H between the support section 41 and the internal teeth forming section 42 along the outer circumferential surface.

[0063] The support part 41 is a rectangular parallelepiped housing having a square bottom surface and a height shorter than each side of the bottom surface, and as shown in FIG. 6(b), a recess 411 that forms an upper space S1 is provided at the end portion of the lower side Hd of the support part 41.

[0064] The recess 411 has an inner diameter slightly larger than the outer diameter of the bottom surface of the truncated cone-shaped retaining portion 22, and is a recess formed by recessing the bottom of the support portion 41 to a depth slightly greater than the height of the retaining portion 22. In other words, the upper space S1 formed by the recess 411 is configured to be able to accommodate the retaining portion 22.

[0065] Further, an upward protrusion 412 that protrudes outward is provided on the outer circumferential surface of the support portion 41 on an upper side Hu from the groove bottom of the recess 411. In this embodiment, the bottom of the upward protrusion 412 corresponds to the groove bottom of the recess 411 (see FIG. 6(b)).

[0066] The internal teeth forming portion 42 has a generally rectangular parallelepiped shape in an undeformed state, and is connected to the lower side Hd of the support portion 41. More specifically, the internal teeth forming portion 42 has a height substantially equal to that of the external teeth forming portion 21 constituting the extension portion 20, and has a generally rectangular parallelepiped shape with side surfaces flush with the outer circumferential surface of the support portion 41. In addition, a downward protruding portion 421 that protrudes outward from the outer circumferential surface beyond the protruding amount of the upper protruding portion 412 is provided at the end of the lower side Hd of the internal teeth forming portion 42.

[0067] The internal tooth forming portion 42 configured in this manner has an insertion portion 44 that forms a lower space S2 along the height direction H in the central portion, and four slits 45 that cut the bottom surface of the internal tooth forming portion 42 along diagonals, as shown in Figures 6(a) and 7.

[0068] The insertion portion 44 has a gear-shaped insertion hole formed in the center of the internal teeth forming portion 42, into which the external locking teeth 23 can be fitted. In detail, as shown in Fig. 7, the insertion portion 44 is composed of a cylindrical portion 441 having a predetermined inner diameter and a circular shape as viewed from the bottom, and a plurality of internal teeth 442 protruding from the cylindrical portion 441 toward the lower space S2.

[0069] The cylindrical portion 441 is a columnar inner peripheral surface having an inner diameter at the center of the internal teeth forming portion 42 that is approximately equal to the distance from the center of the external teeth forming portion 21 that constitutes the extension portion 20 to the apex of the external locking teeth 23. As shown in Figures 6(a) and 7, the internal tooth 442 is an approximately triangular prism having an approximately triangular bottom surface that protrudes radially inward from the cylindrical portion 441 so as to be inclined toward the other circumferential side of the cylindrical portion 441 when viewed from the bottom, and has a predetermined rigidity, similar to the locking external tooth 23.

[0070] More specifically, the angle formed on the radially inner side of the internal teeth 442 protruding from the cylindrical portion 441 is the same as the angle formed by the inner locking surface 231 and the outer locking surface 232 provided on one circumferential side of the inner locking surface 231, i.e., the angle of the valley formed by adjacent locking external teeth 23. The internal teeth 442 are provided from one end to the other end of the cylindrical portion 441 in the height direction H.

[0071] 7, a plurality of the internal teeth 442 configured in this manner are provided at equal intervals along the circumferential direction of the cylindrical portion 441. That is, the internal teeth 442 can fit into a substantially triangular gap formed between the adjacent inner locking surface 231 and outer locking surface 232, and a substantially triangular prism-shaped gap is formed between adjacent internal teeth 442 into which the locking external teeth 23 can fit. Note that since the locking external teeth 23 and the internal teeth 442 have a predetermined rigidity as described above, their shapes are not easily deformed in the fitted state even if an external force is applied.

[0072] The slits 45 are elongated openings that cut the internal teeth forming portion 42 in the height direction H along a diagonal of the square-shaped internal teeth forming portion 42 when viewed from the bottom. That is, the internal teeth forming portion 42 is divided into four equal parts in the circumferential direction by the slits 45. Here, each of the four parts divided by the slits 45 is referred to as a divided forming portion 42x (see FIG. 7).

[0073] In this way, the end of the upper side Hu of the divided forming portion 42x divided in the circumferential direction by the slits 45 is connected to the lower side Hd of the support portion 41 whose plate thickness is thinned by the formation of the recesses 411. Therefore, when an external force acts on the insertion portion 44 in the radially outward direction, the divided forming portion 42x can elastically deform outward with the connection portion with the support portion 41 as a base.

[0074] In addition, the accommodating section 40 constituted by such a support section 41 and an internal tooth forming section 42 has an opening formed on the lower side Hd by the insertion section 44, and has an accommodating space S therein constituted by an upper space S1 formed by the recess 411 and a lower space S2 formed by the insertion section 44.

[0075] The regulating reinforcement member 43 is an annular body that surrounds the outer circumferential surface of the support portion 41 in the circumferential direction. The plate thickness of the regulating reinforcement member 43 is longer than the protruding amount of the upward protruding portion 412 and shorter than the protruding amount of the divided forming portion 42x. In addition, the corners of the upper and lower ends of the surface of the regulating reinforcement member 43 that faces the storage portion 40 are chamfered (not shown), and the regulating reinforcement member 43 is configured to be movable in the height direction H along the outer circumferential surface of the storage portion 40 when the internal teeth forming portion 42 is not deformed.

[0076] The connecting and fixing portion 2 and the retaining connecting portion 3 configured in this manner can be connected together by accommodating the extension portion 20 in the accommodating portion 40, thereby forming a harness retaining member 1 in which the extension direction (hereinafter referred to as the extension direction) of the wire harness WH held by the band fixing portion 30 can be easily changed even after the anchor portion 10 is fixed to the body panel P.

[0077] Hereinafter, a harness holding member 1 capable of holding the wire harness WH and a method for changing the extending direction of the wire harness WH will be described with reference to Figs. 8 to 10. Figs. First, the connecting and fixing part 2 and the holding connecting part 3 are arranged so that the extension part 20 and the storage part 40 face each other along the height direction H, and the extension part 20 is inserted from an opening provided on the lower side Hd of the storage part 40.

[0078] In detail, in a state where the extension portion 20 is arranged to face the insertion portion 44 along the height direction H, the connection fixing portion 2 and the holding connection portion 3 are moved relatively to approach each other in the height direction H. This allows the retaining portion 22, whose tip has a tapered shape, to be inserted into the opening. Here, since the outer diameter of the surface provided on the upper side Hu of the retaining portion 22 is equal to the outer diameter of the cylindrical portion 441, the outer peripheral surface of the retaining portion 22 interferes with the internal teeth 442 during insertion. This causes an external force to act radially outward on each of the divided forming portions 42x. Therefore, the divided forming portions 42x deform radially outward with the support portion 41 as a base. That is, since the opening is enlarged in diameter, the retaining portion 22 can be easily inserted into the lower space S2.

[0079] Then, by further moving the connecting and fixing part 2 and the holding connecting part 3 relatively in the height direction H so as to approach each other, the retaining part 22 that has passed through the upper space S1 is inserted into the lower space S2. As a result, the outer peripheral surface of the retaining part 22 and the insertion part 44 no longer come into contact with each other, and the split forming part 42x returns to its original shape as shown in FIG. 8(a).

[0080] When the split forming portion 42x returns to its original shape, the multiple locking external teeth 23 protruding from the cylindrical main body 211 and the multiple internal teeth 442 protruding radially inward from the cylindrical portion 441 engage with each other (see Figure 9 (b)).

[0081] Then, by engaging the locking external teeth 23 with the internal teeth 442, the extension portion 20 and the storage portion 40 are connected so that the anchor portion 10 and the band fixing portion 30 do not rotate relatively around the central axis of the extension portion 20 in a plan view as the axis of rotation. Note that, when the extension portion 20 is stored in the storage space S, the retaining surface portion 221 abuts against the upper surface portion of the internal teeth forming portion 42, so that the extension portion 20 can be prevented from falling off from the storage portion 40.

[0082] In this manner, by connecting the connecting and fixing part 2 and the holding connecting part 3 via the extending part 20 and the accommodating part 40, it is possible to manufacture a harness holding member 1 in which the anchor part 10 and the band fixing part 30 are integrated. The extending part 20 and the accommodating part 40 that connect the connecting and fixing part 2 and the holding connecting part 3 constitute the connecting part 4 (see FIG. 1).

[0083] Next, the wire harness WH is held by the band fixing portion 30 at 1 connecting the connecting fixing portion 2 and the holding connecting portion 3, and the anchor portion 10 is inserted into the anchor insertion hole P1 in the body panel P, thereby fixing the wire harness WH to the body panel P.

[0084] More specifically, the buckle portion 31, which is disposed on the upper side Hu of the band portion 32 and wound around the wire harness WH, is inserted into the band insertion portion 311 and engaged with the locking piece 312. This allows the band fixing portion 30 to hold the wire harness WH. With the band fixing portion 30 holding the wire harness WH in this manner, the anchor portion 10 is inserted into the anchor insertion hole P1, whereby the wire harness WH extending along the longitudinal direction L can be fixed to the body panel P (see FIG. 9(a)).

[0085] In this manner, the harness holding member 1 that fixes the wire harness WH to the body panel P can change the extension direction of the wire harness WH by relatively rotating the extension portion 20 and the accommodating portion 40 even after the harness holding member 1 is fixed to the body panel P. Below, a brief description will be given of a case where a rotational force F1 is applied to the holding connecting portion 3 so as to rotate the band fixing portion 30 that holds the wire harness WH toward one side in the circumferential direction with the anchor portion 10 as the rotation axis.

[0086] Because the anchor insertion hole P1 provided in the body panel P and the insertion shaft portion 11 inserted into the anchor insertion hole P1 are both elliptical in plan view, the anchor portion 10 engaged and fixed in the anchor insertion hole P1 cannot rotate about the insertion shaft portion 11 as a rotation axis. Therefore, when a rotational force F1 is applied to the band fixing portion 30 such that the band fixing portion 30, which holds the wire harness WH, rotates to one side in the circumferential direction about the anchor portion 10 as the rotation axis, the accommodating portion 40 formed integrally with the band fixing portion 30 tries to rotate to one side in the circumferential direction about the extension portion 20 as the rotation axis.

[0087] Here, the extension portion 20 and the storage portion 40 constituting the connecting portion 4 have a plurality of internal teeth 442 protruding from the cylindrical portion 441 and the locking external teeth 23 protruding from the external teeth forming portion 21 fitted between them, so that the rotation of the storage portion 40 relative to the extension portion 20 can be restricted (see FIG. 10(a)). Therefore, even if an external force that rotates the band fixing portion 30 that holds the wire harness WH around the anchor portion 10 as a rotation axis is unintentionally applied, the band fixing portion 30 can be prevented from rotating. In other words, the locking external teeth 23 and the internal teeth 442 function as a rotation restriction mechanism that restricts the rotation of the storage portion 40 relative to the extension portion 20.

[0088] In this state, by increasing the rotational force F1 acting on the band fixing part 30, the outer locking surface 232 of the fixed external locking teeth 23 presses the internal teeth 442 radially outward, as shown in Fig. 10(b). In other words, the rotational force F1 acting on the band fixing part 30 is converted into a pressing force F2 that moves the internal teeth 442 radially outward.

[0089] Since the pressing force F2 acts on the internal teeth 442 in this way, as shown in Fig. 10(b), the divided forming portions 42x divided in the circumferential direction by the slits 45 deform radially outward with the connecting portions with the support portion 41 as base portions. This causes the lower space S2 formed by the insertion portion 44 to expand, and the restriction between the locking external teeth 23 and the internal teeth 442 is relaxed. Therefore, the restriction on the relative rotation between the extension portion 20 and the band fixing portion 30 is relaxed, and the accommodation portion 40 can be rotated toward one side in the circumferential direction.

[0090] In this state, by further increasing the rotational force F1 so as to rotate the band fastening part 30 towards one side in the circumferential direction, an even greater pressing force F2 acts on the split forming part 42x. As a result, the split forming part 42x is pushed out and deformed so that the internal teeth 442 move radially outward along the outer locking surface 232.

[0091] 10(c), the split forming portion 42x is further deformed radially outward until the apex of the internal tooth 442 is positioned corresponding to the apex of the external locking tooth 23, whereby the internal tooth 442 is released from the locking of the external locking tooth 23, and the band fixing portion 30 can be rotated in one circumferential direction by the distance between the adjacent external locking teeth 23. In other words, the split forming portion 42x, which is deformed radially outward by the application of a predetermined load, pressing force F2, functions as a restriction relaxation mechanism that relaxes the restriction on the relative rotation between the extension portion 20 and the storage portion 40 by the external locking tooth 23 and the internal tooth 442.

[0092] In addition, by releasing the engagement between the internal teeth 442 and the external teeth 23, the external teeth 23 and the internal teeth 442 are no longer in contact with each other, and the split forming portion 42x returns to its original position. As a result, the internal teeth 442 engage with the external teeth 23, restricting the rotation of the extension portion 20 and the storage portion 40.

[0093] In this manner, by applying the rotational force F1 to the band fixing portion 30, the band fixing portion 30 can be rotated to one side in the circumferential direction to extend the wire harness WH in a direction intersecting the longitudinal direction L (see FIG. 9). This makes it possible to prevent the wire harness WH from interfering with other members arranged near the wire harness WH, for example, when the shape of the other members changes. In addition, for example, when the wire harness WH is loose due to tolerance or the like, the tension applied to the wire harness WH can be improved to prevent the wire harness WH from interfering with other members including the body panel P due to vibration or the like.

[0094] When a rotational force F1 is applied to the accommodating portion 40, the restricting reinforcement member 43 is moved to the upper side Hu from the upper protruding portion 412, thereby making it possible to deform the divided formation portion 42x. On the other hand, when it is desired to fix the extension direction of the wire harness WH, the restricting reinforcement member 43 is moved to the lower side Hd so as to surround the outer periphery of the internal teeth formation portion 42. This reliably prevents the divided formation portion 42x from deforming radially outward, thereby more reliably preventing the divided formation portion 42x from deforming unintentionally and changing the extension direction of the wire harness WH.

[0095] In this embodiment, the locking external teeth 23 are inclined to one side in the circumferential direction so that the inner locking surface 231 and the outer locking surface 232 form an acute angle in a plan view. Therefore, when the accommodating portion 40 is rotated to the other side in the circumferential direction, the inner locking surface 231 presses the inner teeth 442 radially inward, which further restricts the rotation of the accommodating portion 40 to the other side in the circumferential direction. In other words, the accommodating portion 40 can be rotated only to one side in the circumferential direction relative to the extending portion 20.

[0096] As described above, the accommodating portion 40 is configured to be rotatable in only one circumferential direction relative to the extending portion 20, but this is not necessarily limited to the configuration, and the accommodating portion 40 may be configured to be rotatable in both circumferential directions relative to the extending portion 20. For example, by projecting the locking external teeth 23 and the internal teeth 442 to form an equiangular triangle in a plan view, the accommodating portion 40 can be rotated in both circumferential directions relative to the extending portion 20.

[0097] Furthermore, in the above-described harness holding member 1, by rotating the accommodation portion 40 toward one side in the circumferential direction relative to the extension portion 20, the split formation portion 42x is deformed to relax the rotation restriction by the locking external teeth 23 and the internal teeth 442. In other words, the split formation portion 42x, which can be deformed radially outward, functions as a restriction relaxation mechanism that relaxes the rotation restriction by the locking external teeth 23 and the internal teeth 442. However, another restriction relaxation mechanism that relaxes the rotation restriction by the locking external teeth 23 and the internal teeth 442 may be provided.

[0098] Second embodiment A harness holding member 1a provided with a deregulation mechanism different from that of the harness holding member 1 will be described below with reference to FIG.

[0099] Here, Fig. 11(a) shows a schematic enlarged cross-sectional view of the connecting portion 4a of the harness holding member 1a, and Fig. 11(b) shows a schematic cross-sectional view of the connecting portion 4a in a state in which a rotational force F1 is applied to the internal teeth forming portion 42a. Figs. 11(a) and 11(b) are cross-sectional views corresponding to Fig. 4(c).

[0100] In the following description of the harness holding member 1a, the same components as those of the above-described harness holding member 1 are denoted by the same reference numerals and description thereof will be omitted. The harness holding member 1a has the same configuration as the harness holding member 1, except that it has an internal teeth forming portion 42a instead of the internal teeth forming portion 42 and that the restricting reinforcement member 43 is not provided. The internal teeth forming portion 42a of the harness holding member 1a is made of a flexible resin, and has the same configuration as the internal teeth forming portion 42, except that the slit 45 is not provided.

[0101] More specifically, the internal teeth forming portion 42a has an insertion portion 44a that forms a gear-shaped insertion hole in the center. The insertion portion 44a is composed of a cylindrical portion 441 that has a predetermined inner diameter and is circular when viewed from the bottom, and a plurality of internal teeth 442a that protrude from the cylindrical portion 441 toward the lower space S2.

[0102] Except for being made of a flexible resin, the internal teeth 442a have the same configuration as the internal teeth 442. Therefore, the shape of the internal teeth 442a will be deformed when an external force is applied.

[0103] The accommodation portion 40 having such an internal teeth forming portion 42a is connected to the extension portion 20 to form the connection portion 4a. 11(a), in the connecting portion 4a where the extension portion 20 and the storage portion 40a are connected, the locking external teeth 23 protruding from the external teeth forming portion 21 are fitted between a plurality of internal teeth 442a protruding from the cylindrical portion 441. Therefore, even if an external force that rotates the band fixing portion 30 that holds the wire harness WH around the anchor portion 10 as a rotation axis is unintentionally applied, the band fixing portion 30 can be prevented from rotating. In other words, the locking external teeth 23 and the internal teeth 442a function as a rotation restriction mechanism that restricts the rotation of the storage portion 40 relative to the extension portion 20.

[0104] On the other hand, by applying a rotational force F1 to the retaining connection part 3 to rotate the band fixing part 30 toward one side in the circumferential direction, the outer locking surface 232 of the fixed locking external teeth 23 presses the inner teeth 442a radially outward, as shown in Fig. 11(b). That is, the rotational force F1 applied to the band fixing part 30 is converted into a pressing force F2 that moves the inner teeth 442a radially outward.

[0105] Since the pressing force F2 acts on the internal teeth 442a in this way, the internal teeth 442a made of a flexible resin are deformed radially outward as shown in Fig. 11(b). This causes the lower space S2 formed by the internal teeth 442a to expand, and the engagement between the locking external teeth 23 and the internal teeth 442a is relaxed. In other words, the restriction on the relative rotation between the extension portion 20 and the band fixing portion 30 is relaxed, and the band fixing portion 30 can be rotated toward one side in the circumferential direction. Therefore, the extension direction of the wire harness WH held by the band fixing portion 30 can be changed.

[0106] In this way, in the harness holding member 1a, the locking external teeth 23 and the internal teeth 442a, which regulate the rotation of the accommodating portion 40 relative to the extension portion 20, function as a rotation regulation mechanism, and the internal teeth 442a, which deform radially outward due to a predetermined load, i.e., the pressing force F2, function as a regulation relaxation mechanism, thereby achieving the same effect as the harness holding member 1.

[0107] In the above-described harness holding member 1, 1a, the locking external teeth 23 and the internal teeth 442, 442a are fitted together over the entire circumference in the circumferential direction to restrict the relative rotation between the extension portion 20 and the storage portion 40, but, for example, the internal teeth 442 may be fitted together only with a portion of the multiple locking external teeth 23. That is, the locking external teeth 23 and the internal teeth 442, 442a may protrude from only a portion of the cylindrical main body 211 or the cylindrical portion 441. Also, a structure may be used in which the locking external teeth 23 is engaged with one of the multiple locking external teeth 23 provided over the entire circumference in the circumferential direction of the cylindrical main body 211 to restrict rotation.

[0108] Third embodiment The harness holding member 1b having a rotation restriction mechanism that restricts rotation by engaging with one of a plurality of external locking teeth 23 provided around the entire circumferential direction of the cylindrical main body 211 will be described below with reference to Figs. 12 and 13.

[0109] Here, Figure 12(a) shows a schematic side view of the holding connection portion 3b of the harness holding member 1b as viewed from the front side La, Figure 12(b) shows a cross-sectional view along arrow CC in Figure 12(a), and Figure 12(c) shows an enlarged view of portion b in Figure 12(b). Fig. 13(a) shows a schematic enlarged cross-sectional view of the connecting portion 4b of the harness holding member 1b, and Fig. 13(b) shows a schematic cross-sectional view of the connecting portion 4b in a state in which a rotational force F1 is applied to the locking-accommodating portion 46. Fig. 13(a) and Fig. 13(b) are cross-sectional views corresponding to Fig. 12(c).

[0110] In the following description of the harness holding member 1b, the same components as those of the above-mentioned harness holding member 1 are denoted by the same reference numerals and description thereof will be omitted. The harness holding member 1b has the same configuration as the harness holding member 1, except that the harness holding member 1b has a receiving portion 40b instead of the receiving portion 40. The accommodating portion 40b is a roughly rectangular parallelepiped housing smaller than the band fixing portion 30, and is integrally formed with the support portion 41 and a locking accommodating portion 46 whose outer circumferential surface is flush with that of the support portion 41.

[0111] The locking accommodating portion 46 is a roughly rectangular parallelepiped housing having a height roughly equal to that of the external tooth forming portion 21 and a side surface that is flush with the outer peripheral surface of the support portion 41, and as shown in Figures 12(a) and 12(b), is provided with a cylindrical insertion portion 47 that passes through the central portion in the height direction H, a communication window 48 provided in the side wall on the front side La, and an elastic locking piece 49 that covers part of the communication window 48.

[0112] The cylindrical insertion portion 47 is a cylindrical inner peripheral surface provided in the center of the locking-accommodating portion 46, and forms a cylindrical insertion space S3 along the height direction H in the center of the locking-accommodating portion 46. The inner diameter of the cylindrical insertion portion 47 is approximately equal to the distance from the center of the external teeth forming portion 21 to the apex of the external locking teeth 23.

[0113] 12(a) and 12(b), the communication window 48 is a rectangular insertion hole communicating with the outside and the insertion space S3, and is provided in the center of the height direction H of the locking-accommodating portion 46 and in the side wall on the front side La. In detail, the communication window 48 is formed in a rectangular shape having a long side with a length substantially equal to the radius of the cylindrical insertion portion 47 in a bottom view and a short side with a length substantially one-third of the height of the locking-accommodating portion 46. The end of the long side of the communication window 48 on the right side Wr along the width direction W is provided at a position corresponding to the rounded portion of the right side Wr of the cylindrical insertion portion 47.

[0114] As shown in Figures 12(b) and 12(c), the elastic locking piece 49 is composed of an elastic support portion 491 extending from the end of the right side Wr of the communication window 48, and a locking portion 492 protruding from the tip of the elastic support portion 491 toward the insertion space S3.

[0115] The elastic support portion 491 is a plate-like body having a plate thickness of about half the distance between the apex of the cylindrical insertion portion 47 and the outer surface of the locking-accommodating portion 46, and extends from an end portion on the right side Wr to the left side Wl of the communication window 48. The length of the elastic support portion 491 in the width direction W is slightly shorter than the long side of the communication window 48. The locking portion 492 is a triangular prism having a generally right-angled triangular shape in bottom view, configured to be capable of being locked between the locking external teeth 23, and protrudes from the tip portion of the elastic support portion 491 toward the insertion space S3.

[0116] The elastic locking piece 49 configured in this manner is configured so that when an external force acts radially outward on the locking portion 492, the elastic support portion 491 can elastically deform radially outward, with the connection portion with the communicating window 48 as the base point.

[0117] The accommodation portion 40b having such an engaging accommodation portion 46 is coupled to the extension portion 20 to form the coupling portion 4b. 13(a), in the connecting portion 4b, the locking portion 492 protruding from the elastic support portion 491 in the insertion space S3 is locked to the inner locking surface 231 of the locking external teeth 23 protruding from the external teeth forming portion 21. Therefore, even if an external force that rotates the band fixing portion 30 that holds the wire harness WH around the anchor portion 10 as a rotation axis is unintentionally applied, the band fixing portion 30 can be prevented from rotating. In other words, the locking portion 492 that is locked to the inner locking surface 231 and the locking external teeth 23 function as a rotation restriction mechanism that restricts the rotation of the accommodation portion 40 relative to the extension portion 20.

[0118] On the other hand, by applying a rotational force F1 to the holding connection part 3 to rotate the band fixing part 30 toward one side in the circumferential direction, the outer locking surface 232 of the fixed locking external teeth 23 presses the locking part 492 radially outward, as shown in Fig. 13(b). In other words, the rotational force F1 applied to the holding connection part 3 is converted into a pressing force F2 that moves the locking part 492 radially outward.

[0119] By applying the pressing force F2 to the locking portion 492 in this manner, as shown in FIG. 13(b), the elastic support portion 491 is elastically deformed radially outward from the connection portion with the communication window 48 as a base point. This causes the locking portion 492 to move radially outward, and the locking between the locking portion 492 and the locking external teeth 23 is relaxed. In other words, the restriction on the relative rotation between the extension portion 20 and the band fixing portion 30 is relaxed, and the band fixing portion 30 can be rotated toward one side in the circumferential direction. Therefore, the extension direction of the wire harness WH held by the band fixing portion 30 can be changed.

[0120] In this way, in the harness holding member 1b, the locking external teeth 23 and the locking portion 492, which restrict the rotation of the accommodating portion 40 relative to the extension portion 20, function as a rotation restriction mechanism, and the elastic support portion 491, which deforms radially outward due to a predetermined load, i.e., the pressing force F2, functions as a restriction relaxation mechanism, thereby achieving the same effect as the harness holding members 1, 1a.

[0121] Furthermore, in the above-mentioned harness holding members 1, 1a, 1b, the extension portion 20 and the accommodating portions 40, 40a, 40b that constitute the connecting portion 4 are respectively arranged to face the upper side Hu of the anchor portion 10 and the lower side Hd of the band fixing portion 30, but for example, the accommodating portions 40, 40a, 40b may be provided on the upper side Hu of the anchor portion 10, and the extension portion 20 may be provided on the lower side Hd of the band fixing portion 30.

[0122] Furthermore, the above-mentioned harness retaining member 1 is structured to alleviate the rotation restriction between the extension portion 20 and the accommodating portion 40 by deforming the accommodating portion 40 that accommodates the extension portion 20. However, for example, the harness retaining member 1c may be provided with an annular accommodating portion 50 that is hollow and an engaging extension portion 60 that can be accommodated in the annular accommodating portion 50 and is configured to be radially deformable by application of a predetermined external force, and the rotation restriction between the annular accommodating portion 50 and the engaging extension portion 60 is released by application of a predetermined external force to the engaging extension portion 60.

[0123] (Fourth embodiment) Below, a harness holding member 1c having a hollow annular accommodating portion 50 and a locking extension portion 60 configured to be radially deformable by the application of a predetermined external force will be described with reference to Figures 14 to 17.

[0124] Here, Fig. 14(a) shows a schematic cross-sectional view of the harness holding member 1c, Fig. 14(b) shows a schematic enlarged cross-sectional view of the connecting portion 4c in Fig. 14(a), and Fig. 14(c) shows a schematic cross-sectional view of the annular housing portion 50 cut in the height direction H of the annular housing portion 50 in Fig. 14(b). Fig. 15(a) shows a schematic cross-sectional view of the connecting and fixing portion 2c, Fig. 15(b) shows a schematic enlarged cross-sectional view of the annular housing portion 50 in Fig. 15(a), and Fig. 15(c) shows a schematic cross-sectional view of the annular housing portion 50 cut in the height direction H of the annular housing portion 50. Fig. 16(a) shows a schematic side view of the holding connecting portion 3c seen from the rear side Lb, Fig. 16(b) shows a schematic enlarged bottom view of the locking extension portion 60 in the holding connecting portion 3c, and Figs. 17(a) and 17(b) show schematic cross-sectional views of a state in which an inward force F3 is applied to the extension piece 61 in the locking extension portion 60.

[0125] Here, Fig. 14(a) is a cross-sectional view corresponding to Fig. 8(a), and Fig. 15(a) is a cross-sectional view taken along the center of the connecting and fixing part 2c in the width direction W. Also, Fig. 17(a) is a cross-sectional view corresponding to Fig. 14(b), and Fig. 17(b) is a cross-sectional view corresponding to Fig. 14(c).

[0126] In the following description of the harness holding member 1c, the same components as those of the above-described harness holding member 1 are denoted by the same reference numerals and description thereof will be omitted. As shown in Figure 14, the harness holding member 1c has a structure in which a connecting and fixing portion 2c consisting of an anchor portion 10 and an annular accommodating portion 50 is connected to a holding and connecting portion 3c consisting of a band fixing portion 30 and an engaging extension portion 60. As shown in Figures 14 and 15, the annular accommodating portion 50 is a hollow cylinder having an opening on the upper side Hu for inserting the locking extension portion 60, and having an accommodating space Sc inside capable of accommodating the locking extension portion 60.

[0127] In detail, as shown in Figures 15(a) and 15(b), the annular accommodating portion 50 is composed of a cylindrical body 51 erected on the upper side Hu of the anchor portion 10, and an accommodating recess 52 in which the central portion of the cylindrical body 51 is recessed toward the lower side Hd.

[0128] The accommodating recess 52 provided in the central portion of a cylindrical body 51 having a predetermined outer diameter in a plan view is composed of an inner peripheral portion 521 forming the inner surface of the annular accommodating portion 50, and a plurality of locking internal teeth 522 protruding radially inward from the inner peripheral portion 521, as shown in Figures 15(b) and 15(c).

[0129] 15(c), the locking internal teeth 522 have a generally isosceles trapezoidal shape in plan view that tapers radially inward, and a plurality of them are provided at equal intervals along the circumferential direction of the inner peripheral portion 521. That is, a recess having an isosceles trapezoidal shape in plan view is formed between adjacent locking internal teeth 522. Note that the surface of the locking internal teeth 522 along the radial direction is defined as an isosceles locking surface 523.

[0130] In addition, at the end of the upper side Hu of the inner peripheral portion 521, as shown in Figures 15(b) and 15(c), an annular protrusion 524 is provided which protrudes radially inward from the inner edge slightly longer than the locking inner teeth 522.

[0131] As shown in Figures 16(a) and 16(b), the locking extension portion 60 is composed of a pair of extension pieces 61 extending from the bottom surface of the buckle portion 31, extended external teeth 62 protruding radially outward from the tip of the extension piece 61, and a pressing portion 63 protruding radially outward from the extension piece 61.

[0132] The pair of extension pieces 61 are each formed in a flat plate shape having a predetermined plate thickness, and are provided at a predetermined interval so as to face each other in the radial direction. The length of the extension pieces 61 in the height direction H is greater than the height of the annular housing portion 50. The interval between the extension pieces 61 is shorter than half the inner diameter of the inner circumferential portion 521.

[0133] 16(b), the extending external teeth 62 protrude radially outward from the central portion of the width of the extending piece 61. More specifically, the extending external teeth 62 have a generally isosceles trapezoidal shape in bottom view that tapers radially outward, and are configured to be able to fit into recesses formed between adjacent locking internal teeth 522. The end of the extending external teeth 62 on the lower side Hd is chamfered so as to be inclined radially inward as it approaches the lower side Hd.

[0134] 16(a) and 16(b), the pressing portion 63 protrudes radially outward from the extending piece 61 between the bottom surface of the buckle portion 31 and the extending outer teeth 62. The pressing portion 63 protrudes radially outward beyond the outer edge of the annular housing portion 50.

[0135] The locking extension portion 60 configured in this manner is configured so that, when an external force is applied radially inward, the extension piece 61 can elastically deform radially inward, with the connection point between the extension piece 61 and the buckle portion 31 as the base point.

[0136] The annular receiving portion 50 and the locking extension portion 60 configured in this manner can be connected to each other by inserting the locking extension portion 60 into the annular receiving portion 50 . More specifically, by inserting the locking extension portion 60 into the opening provided in the annular housing portion 50, the lower end of the extending external teeth 62 interferes with the annular protrusion portion 524, so that an external force acts on the extending external teeth 62 in a radially inward direction, and the extending piece 61 elastically deforms in a radially inward direction from the connection point with the buckle portion 31. As a result, the tip portion of the extending external teeth 62 is positioned inside the annular protrusion portion 524, and the extending external teeth 62 can be inserted into the insertion space S3.

[0137] Then, by inserting the extended external teeth 62 into the insertion space S3, the interference between the annular protrusion 524 and the extended external teeth 62 is eliminated, and the extended piece 61 returns to its original shape. As a result, the extended external teeth 62 fit between the locking internal teeth 522, and the extended external teeth 62 are locked to the isopod locking surface 523. That is, the locking extension portion 60 is restricted from rotating relative to the annular housing portion 50 (see FIG. 14(c)). In this way, the locking internal teeth 522 and the extended external teeth 62 that restrict the rotation of the locking extension portion 60 relative to the annular housing portion 50 function as a rotation restriction mechanism. The annular housing portion 50 and the locking extension portion 60 thus connected constitute the connecting portion 4c.

[0138] In addition, when the extending external teeth 62 are fitted between the locking internal teeth 522, an inward force F3 directed radially inward is applied to the extending piece 61 via the pressing portion 63 exposed from the annular housing portion 50, so that the extending piece 61 elastically deforms radially inward from the connecting portion with the buckle portion 31 as a base point, as shown in Fig. 17, and the fitting between the locking internal teeth 522 and the extending external teeth 62 can be released. In other words, the extending piece 61, which can deform radially inward due to the inward force F3, which is a predetermined load, functions as a deregulation mechanism. This allows the locking extension portion 60 to rotate relative to the annular housing portion 50, and the extending direction of the wire harness WH held by the band fixing portion 30 can be changed.

[0139] As described above, the harness holding members 1, 1a, 1b, 1c are equipped with the band fixing portion 30 that holds the wire harness WH, the anchor portion 10 that is fixed to the vehicle (body panel P), the connecting portion 4 that connects the anchor portion 10 and the band fixing portion 30 so as to be able to rotate relative to one another, a rotation restriction mechanism that restricts the rotation between the anchor portion 10 and the band fixing portion 30, such as the locking external teeth 23 and the internal teeth 442, 442a, the locking external teeth 23 and the locking portion 492, or the locking internal teeth 522 and the extending external teeth 62, and a restriction relaxation mechanism that relaxes the restriction on the relative rotation between the anchor portion 10 and the band fixing portion 30 by the rotation restriction mechanism, such as the split formation portion 42x, the internal teeth 442a, the elastic support portion 491, and the extending piece 61.

[0140] The harness holding members 1, 1a, 1b, and 1c described above can easily change the extending direction of the wire harness WH even after being fixed to the vehicle. In detail, by providing a rotation restriction mechanism such as the locking external teeth 23 and the internal teeth 442, 442a, the locking external teeth 23 and the locking portion 492, or the locking internal teeth 522 and the extending external teeth 62, the rotation between the anchor portion 10 and the band fixing portion 30 can be restricted, and the extending direction of the wire harness WH relative to the anchor portion 10 can be restricted. On the other hand, by providing a restriction relaxation mechanism such as the divided forming portion 42x, the internal teeth 442a, the elastic support portion 491, and the extending piece 61, in a state in which the rotation between the anchor portion 10 and the band fixing portion 30 is restricted, a predetermined external force can be applied to relax the rotation restriction between the anchor portion 10 and the band fixing portion 30 by the rotation restriction mechanism. As a result, the anchor portion 10 and the band fixing portion 30 can be rotated relative to each other, and the extending direction of the wire harness WH restricted by the rotation restriction mechanism can be changed to a desired direction.

[0141] Furthermore, by reducing the applied specified external force, the rotation restriction mechanism can again restrict the rotation of the anchor portion 10 and the band fixing portion 30, so that the extension direction of the wire harness WH can be fixed with the wire harness WH changed to the desired extension direction.

[0142] In this way, by providing the rotation restriction mechanism and the restriction relaxation mechanism, the band fixing part 30, whose rotation is restricted with respect to the anchor part 10, can be rotated relatively to a desired angle, and the relative rotation between the anchor part 10 and the band fixing part 30, which has been changed to the desired angle, can be restricted. Therefore, even after the anchor part 10 is fixed at a predetermined position, the extension direction of the wire harness WH held by the band fixing part 30 connected to the anchor part 10 via the connecting part 4 can be changed and that state can be maintained.

[0143] In addition, the connecting portion 4 has an extension portion 20 and an engaging extension portion 60 that are provided on the anchor portion 10 and extend from the anchor portion 10 toward the band fixing portion 30, and accommodating portions 40, 40a, 40b and an annular accommodating portion 50 that are provided on the band fixing portion 30, which is on the opposite side of the anchor portion 10 where the extension portion 20 and the engaging extension portion 60 are provided, and accommodate at least a portion of the extension portion 20 and the engaging extension portion 60.

[0144] This allows the anchor part 10 and the band fixing part 30 to be connected with a simple structure in which the extension part 20 and the locking extension part 60 are simply accommodated in the accommodation parts 40, 40a, 40b and the annular accommodation part 50. Furthermore, since at least a part of the extension part 20 and the locking extension part 60 are accommodated in the accommodation spaces in the accommodation parts 40, 40a, 40b and the annular accommodation part 50, it is possible to prevent the extension part 20 and the locking extension part 60 from falling off from the accommodation parts 40, 40a, 40b and the annular accommodation part 50 even if an unintended external force acts on the connecting part 4. Therefore, it is possible to prevent the connection between the anchor part 10 and the band fixing part 30 from being easily released.

[0145] In addition, in the harness holding member 1, 1a, the direction perpendicular to the circumferential direction corresponding to the rotational direction in which the anchor portion 10 and the band fixing portion 30 rotate relative to each other is the radial direction, and a plurality of locking external teeth 23 having an inner locking surface 231 and an outer locking surface 232 are provided on the outer surface of the cylindrical main body 211 facing radially, and inner teeth 442, 442a that lock with the inner locking surface 231 and the outer locking surface 232 are provided in the insertion portion 44 of the internal tooth forming portion 42, and the locking external teeth 23 and the internal teeth 442, 442a function as a rotation restricting mechanism, and 442a, which is composed of a split forming portion 42x and an elastic member, which is a restriction relaxation mechanism, relaxes the locking of the locking surface by the inner teeth 442, 442a and the elastic locking piece 49.

[0146] This makes it possible to reliably lock the anchor part 10 and the band fixing part 30 with a simple structure of simply locking the internal teeth 442, 442a to the internal locking surface 231. Furthermore, because the locking between the external locking teeth 23 and the internal teeth 442, 442a is performed within the accommodation space S in the accommodation parts 40, 40a, it is possible to prevent the rotation restriction by the locking between the internal locking surface 231 and the internal teeth 442, 442a from being unintentionally released.

[0147] The extension portion 20 extends along the axis of relative rotation, and a plurality of locking external teeth 23 are provided on the outer surface of the extension portion 20 along the rotation direction (circumferential direction), and a plurality of internal teeth 442, 442a are provided on the inner surface of the storage portion 40, 40a along the rotation direction, and the locking external teeth 23 and the internal teeth 442, 442a fit together in the radial direction to function as a rotation restricting mechanism, and the split forming portion 42x, which is a restriction relaxation mechanism, 442a made of an elastic member relaxes the fit between the locking external teeth 23 and the internal teeth 442, 442a. As a result, the locking external teeth 23 provided along the rotation direction fit together with the internal teeth 442, 442a, so that the relative rotation between the anchor portion 10 and the band fixing portion 30 can be reliably restricted.

[0148] Furthermore, the accommodating portion 40, 40a has an internal tooth forming portion 42, 42a with internal teeth 442, 442a provided on its inner surface, and the internal tooth forming portion 42, 42a is configured to deform radially outwardly when a predetermined load is applied, and the internal tooth forming portion 42, 42a, which deforms radially outwardly when a predetermined load is applied, functions as a deregulation mechanism.

[0149] This makes it possible to restrict unintentional rotation of the connecting and fixing part 2 and the holding and connecting part 3, and also makes it possible to easily change the extending direction of the wire harness WH by applying a predetermined load to the internal teeth forming parts 42, 42a. In more detail, in a state in which the relative rotation between the anchor part 10 and the band fixing part 30 is restricted by the internal teeth 442, 442a and the locking external teeth 23 that are fitted together in the radial direction, by increasing the rotational force F1 acting in a direction that rotates the anchor part 10 and the band fixing part 30 relative to each other, the applied rotational force F1 is converted into a pressing force F2 that deforms the internal teeth forming parts 42, 42a radially outward. This makes it possible to deform the internal teeth forming parts 42, 42a radially outward, relaxing the fit between the internal teeth 442, 442a and the locking external teeth 23, and allowing the anchor part 10 and the band fixing part 30 to rotate relative to each other.

[0150] In this way, since the internal teeth forming portions 42, 42a are configured to deform radially outward under a predetermined load, only when a rotational force F1 equal to or greater than a predetermined value is applied, the internal teeth forming portions 42, 42a are deformed radially outward to relax the engagement between the internal teeth 442, 442a and the locking external teeth 23. This allows the anchor portion 10 and the band fixing portion 30 to rotate relative to each other. Therefore, unintended rotation of the anchor portion 10 and the band fixing portion 30 can be restricted, and the extension direction of the wire harness WH can be changed.

[0151] Moreover, in the harness holding member 1, the housing portion 40 is provided with slits 45 that divide the internal teeth forming portion 42 into a plurality of portions along the rotational direction. As a result, the internal teeth forming portion 42 can be divided into a plurality of divided forming portions 42x by the slits 45, and therefore the influence of deformation of each divided forming portion 42x into which the internal teeth forming portion 42 is divided on the deformation of the other divided forming portions 42x can be reduced. In other words, the deformability of the divided internal teeth forming portion 42 can be improved. Therefore, the locking between the internal teeth 442 and the locking external teeth 23 can be more reliably relaxed.

[0152] Furthermore, the internal teeth forming portion 42 is formed in a quadrangular shape when viewed from a direction along the rotation axis in the rotation direction, and the slit 45 is formed so as to pass through the apex of the quadrangular internal teeth forming portion 42. This allows the internal teeth forming portion 42 to be divided so as not to include the apex portion. In other words, when the internal teeth forming portion 42 is deformed radially outward, the resistance applied when each divided forming portion 42x obtained by dividing the internal teeth forming portion 42 is deformed radially outward can be reduced compared to when the internal teeth forming portion 42 is divided so as to include the apex portion. This allows the deformability of the divided forming portion 42x to be further improved, and the engagement between the internal teeth 442 and the locking external teeth 23 can be relaxed with a smaller rotational force F1. Therefore, the anchor portion 10 and the band fixing portion 30 can be easily rotated relative to each other.

[0153] Furthermore, by providing the restricting reinforcement member 43 that restricts radial deformation of the internal tooth forming portion 42, it is possible to restrict the radial outward movement of the divided forming portion 42x, thereby reliably restricting the relative rotation between the anchor portion 10 and the band fixing portion 30. In other words, after the extension direction of the wire harness WH is changed, it is possible to prevent the anchor portion 10 and the band fixing portion 30 from rotating relative to each other, thereby preventing the extension direction of the wire harness WH from being further changed.

[0154] On the other hand, the internal teeth forming portion 42a of the harness holding member 1a is made of an elastic body that is elastically deformed by a predetermined load. Therefore, only when a rotational force F1 equal to or greater than a predetermined value is applied, the internal teeth forming portion 42a is elastically deformed radially outward to relax the engagement between the internal teeth 442a and the locking external teeth 23. This allows the anchor portion 10 and the band fixing portion 30 to rotate relative to each other. Therefore, unintended rotation of the anchor portion 10 and the band fixing portion 30 can be restricted, and the extending direction of the wire harness WH can be changed.

[0155] In addition, in the harness holding member 1b, the direction perpendicular to the circumferential direction corresponding to the rotational direction in which the anchor portion 10 and the band fixing portion 30 rotate relative to each other is defined as the radial direction, and a plurality of external locking teeth 23 having an inner locking surface 231 and an outer locking surface 232 facing radially are provided on the outer surface of the cylindrical main body 211, and an locking portion 492 that locks with the inner locking surface 231 and the outer locking surface 232 is provided at the tip of the elastic locking piece 49, and the external locking teeth 23 and the locking portion 492 function as a rotation restriction mechanism, and 442a composed of a split forming portion 42x and an elastic member, which is a restriction relaxation mechanism, may relax the locking of the internal teeth 442, 442a and the locking portion 492 to the locking surface.

[0156] This makes it possible to reliably lock the anchor part 10 and the band fixing part 30 with a simple structure of simply locking the internal teeth 442, 442a or the locking part 492 to the internal locking surface 231. Furthermore, since the locking between the external locking teeth 23 and the internal teeth 442, 442a, or between the external locking teeth 23 and the locking part 492 is performed within the accommodation space S in the accommodation parts 40, 40a, 40b, it is possible to prevent the rotation restriction by the locking between the internal locking surface 231 and the internal teeth 442, 442a or the locking part 492 from being unintentionally released.

[0157] In the harness holding member 1b, the elastic locking piece 49 has an elastic support portion 491 that elastically supports the locking against the inner locking surface 231 and the outer locking surface 232 so as to urge the locking against the inner locking surface 231 and the outer locking surface 232 in the rotational direction, and the elastic support portion 491 functions as a restriction relaxation mechanism. As a result, the elastic locking piece 49, which is elastically supported so as to be biased in the rotational direction by the elastic support portion 491, can be locked to the inner locking surface 231 and the outer locking surface 232, thereby reliably restricting rotation of the anchor part 10 and the band fixing part 30. On the other hand, when a predetermined external force is applied in the rotational direction, the elastic support portion 491 elastically deforms and the lock between the outer locking surface 232 and the elastic locking piece 49 (locking portion 492) is released, allowing the anchor part 10 and the band fixing part 30 to rotate relative to each other.

[0158] In this way, the elastic locking piece 49 has the elastic support portion 491 that elastically supports the locking against the inner locking surface 231 and the outer locking surface 232 so as to urge the locking against the inner locking surface 231 and the outer locking surface 232 in the rotational direction, and therefore the elastic support portion 491 elastically deforms and the locking between the outer locking surface 232 and the elastic locking piece 49 can be released only when a predetermined external force is applied. Therefore, unintended rotation of the anchor part 10 and the band fixing part 30 can be restricted, and by intentionally applying a predetermined external force, the anchor part 10 and the band fixing part 30 can be rotated relative to each other to change the extension direction of the wire harness WH.

[0159] Furthermore, in the harness holding members 1, 1a, and 1b, the deregulation mechanism relaxes the restriction on one-way relative rotation between the anchor part 10 and the band fixing part 30. This allows the relative rotation between the anchor part 10 and the band fixing part 30 to be only in one direction along the rotation direction, thereby preventing unintentional rotation in the other direction.

[0160] In addition, in the harness holding member 1c, the locking extension portions 60 are provided in multiple locations spaced apart in the radial direction and are configured to be elastically deformable along the radial direction, with multiple locking inner teeth 522 having isopod locking surfaces 523 facing radially being provided on the inner surface of the annular accommodating portion 50, and extended outer teeth 62 that lock with the isopod locking surfaces 523 being provided on the outer surface of the locking extension portion 60, with the locking inner teeth 522 and the extended outer teeth 62 functioning as a rotation restriction mechanism, and the elastic deformation of the locking extension portion 60 along the radial direction functioning as a restriction relaxation mechanism.

[0161] As a result, the engagement between the locking inner teeth 522 and the extending outer teeth 62 can be released by elastically deforming the multiple locking extensions 60 toward one side in the radial direction. Therefore, the anchor part 10 and the band fixing part 30 can be easily rotated relative to each other. On the other hand, since the locking extensions 60 are configured to be elastically deformable in the radial direction, a restoring force acts on the locking extensions 60 as the elastic deformation of the locking extensions 60 is released. As a result, the locking extensions 60 can be restored toward the other side in the radial direction, and the locking inner teeth 522 and the extending outer teeth 62 can be engaged with each other. Therefore, the relative rotation between the anchor part 10 rotated to a desired extension direction and the band fixing part 30 can be restricted.

[0162] In the configuration of the present invention and the correspondence between the above-mentioned embodiment, the wire harness of the present invention corresponds to the wire harness WH. The harness holding portion corresponds to the band fixing portion 30, The fixing portion corresponds to the anchor portion 10, The connecting parts correspond to the connecting parts 4, 4a, 4b, and 4c, The rotation restriction mechanism corresponds to the locking external teeth 23 and the internal teeth 442, 442a, the locking external teeth 23 and the locking portion 492, the locking internal teeth 522 and the extending external teeth 62, The deregulation mechanism corresponds to the divided forming portion 42x, the internal teeth 442a, the elastic support portion 491, and the extension piece 61. The harness holding members correspond to the harness holding members 1, 1a, 1b, and 1c, The extension portion corresponds to the extension portion 20 and the locking extension portion 60, The receiving portion corresponds to the receiving portion 40, 40a, 40b and the annular receiving portion 50, The locking surfaces correspond to the inner locking surface 231 and the outer locking surface 232, or the isopod locking surface 523; The locking teeth correspond to the locking external teeth 23, The locking portion corresponds to the internal teeth 442, 442a and the elastic locking piece 49. The elastic support portion corresponds to the elastic support portion 491, The external teeth correspond to the locking external teeth 23, The inner teeth correspond to the inner teeth 442 and 442a. The internal teeth forming portion corresponds to the internal teeth forming portion 42, The slit corresponds to slit 45, The deformation restricting portion corresponds to the restricting reinforcing member 43, The locking surface corresponds to the isopod locking surface 523, The locked portion corresponds to the receiving recess 52, The locking portion corresponds to the extended external teeth 62, but the present invention is not limited to the configuration of the above-mentioned embodiment, and many embodiments can be obtained.

[0163] For example, in this embodiment, the anchor portion 10 is a so-called anchor that is inserted into the anchor insertion hole P1 and engaged and fixed, but there is no particular limitation as long as it can be fixed to the vehicle, and for example, it may have a sliding structure that slides and fixes it to a stay or clip provided at a predetermined location.

[0164] For example, like the harness holding member 1 in this embodiment, the connecting portion 4 has a structure in which the extension portion 20 and the storage portion 40 are connected, but the extension portion 20 and the storage portion 40 may be connected via a separate member. In this case, the rotation of the extension portion 20 and the storage portion 40 may be restricted via the separate member.

[0165] Furthermore, in the harness holding member 1 of the present embodiment, the internal teeth forming portion 42 has a regular quadrangle shape when viewed from the bottom, but it may have any polygonal shape, such as a regular hexagon or regular octagon, or a rhombus or parallelogram. In the harness holding member 1 of this embodiment, the slits 45 are cut along a diagonal line, but this does not necessarily have to be diagonal, and the cuts may be made along lines connecting points other than the center to each vertex.

[0166] In addition, in the harness holding member 1 of the present embodiment, a restricting reinforcement member 43 is provided that surrounds the outer periphery of the internal teeth forming portion 42 and restricts the radial deformation of the divided forming portion 42x, but the present invention is not limited to this configuration as long as it can restrict the radial deformation of the internal teeth forming portion 42. For example, the configuration may be such that the radial outward deformation of the divided forming portion 42x is restricted by fixing adjacent internal teeth forming portions 42 to each other. Note that the restricting reinforcement member 43 may be configured integrally with the internal teeth forming portion 42, or may be configured as a separate member that can be attached to the internal teeth forming portion 42.

[0167] In addition, in the harness holding member 1a, the locking external teeth 23 and the internal teeth 442a are engaged with each other, but a gap may be provided between the locking external teeth 23 and the internal teeth 442a. In this case, the restriction on rotation between the extension portion 20 and the band fixing portion 30 can be relaxed with a smaller rotational force F1.
