Description

[Technical Field]

[0001] The present invention relates to a fixing member and a wire harness with a fixing member that attaches and fixes an elongated member to an attachment base, for example, that is mounted on a vehicle. [Background technology]

[0002] Fixing members have been widely used to attach and secure elongated members such as wire harnesses mounted on vehicles to workpieces such as vehicle body panels and electrical junction boxes. Patent Document 1 discloses a clamp as such a fixing member, which has a plate-shaped holding portion that holds the elongated member, the wire harness, by tape, and an anchor that secures the holding portion by inserting it into a through-hole provided in the workpiece, the vehicle body panel. The clamp disclosed in Patent Document 1 can fix the elongated member, the wire harness, to the vehicle body panel while regulating its path along a desired routing path.

[0003] However, with the clamp described in Patent Document 1, when a wire harness is fixed to a movable attachment member such as a door panel, the movement of the attachment member can cause bending or twisting of the wire harness fixed to the holding portion with tape, potentially applying a load to the wire harness.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 11-243624 Summary of the Invention [Problem to be solved by the invention]

[0005] SUMMARY OF THE INVENTION An object of the present invention is to provide a fixing member that can reduce the load acting on an elongated member attached to a workpiece when the workpiece moves. [Means for solving the problem]

[0006] This invention is characterized in that the fixing member comprises a holding portion that holds a long member to be attached to a workpiece, an insertion-fixing portion that is inserted into a through hole provided in the workpiece and fixed to the workpiece, and a spacing-retaining portion that, when attached to and fixed to the workpiece, maintains a gap between the workpiece and the holding portion by separating them in the insertion direction in which the insertion-fixing portion is inserted into the through hole, wherein the insertion-fixing portion is provided with an insertion shaft that is inserted into the through hole and a plurality of extension pieces that extend from the insertion shaft so as to move away from the insertion shaft as they move in the opposite direction to the insertion direction, and at least one of the extension pieces and the spacing-retaining portion reduces in diameter as they move toward the other along the insertion direction, and wherein, in the fixed state, the fixing member has a sliding portion that abuts against the inner surface of the through hole and slides along the inner surface as it moves relative to the workpiece.

[0007] The present invention is also characterized in that it is a wire harness with a fixing member, which comprises a wire harness that is a long member to be attached to a receiving member, and the above-mentioned fixing member, and the wire harness is held in the holding portion.

[0008] The mounting member refers to a member that moves relative to the attached holding part, and includes, for example, a door panel that can be moved by opening and closing, a sliding seat that moves in the fore-and-aft direction of the vehicle, and an electrical connection box that is affected by vehicle vibrations, etc.

[0009] The long members include wire harnesses, communication cables, tubes, and the like. The holding portion is capable of holding the elongated member, and includes, for example, a flat plate that fixes and holds the elongated member, a band portion that is wrapped around the outer circumference of the elongated member to hold the elongated member, and a structure that holds a connector provided at the end of the elongated member, such as a through structure.

[0010] According to this invention, the load acting on the elongated member attached to the workpiece due to movement of the workpiece can be reduced. In more detail, the device is provided with an insertion shaft that is inserted into a through hole provided in the member to be attached, and an insertion fixing portion and a spacing retaining portion that have an extension piece extending from the insertion shaft, so that the retaining portion that holds the long member can be attached and fixed to the member to be attached while being spaced apart in the insertion direction from the member to be attached.

[0011] Furthermore, at least one of the extension piece and the spacing retaining part has a sliding part that abuts and slides against the inner circumferential surface of the through hole, so that the sliding part can slide along the inner circumferential surface of the through hole to change the angle of the retaining part relative to the workpiece. Therefore, when an external force acts on the elongated member as the workpiece moves, the fixing member can appropriately change the angle of the retaining part relative to the workpiece, thereby reducing the load acting on the elongated member held in the retaining part.

[0012] As an aspect of the present invention, the sliding portion may have a cross-sectional arc shape that is convex toward the other of the extension piece and the spacing portion. This invention allows the sliding portion to slide smoothly along the inner circumferential surface of the through hole, so the angle of the fixing member can be smoothly changed in response to the external force acting on the elongated member, and therefore the sliding portion can slide along the inner circumferential surface of the through hole in accordance with the movement of the attached member.

[0013] In another aspect of the present invention, the other of the extending piece and the spacing retaining portion may be a biasing member that can bias toward the one of them. According to this invention, in the fixed state, the workpiece can be securely clamped between the extension piece and the spacing retaining portion while applying a biasing force, so that the retaining portion can be stably attached to the workpiece.

[0014] Furthermore, since the sliding portion can slide along the inner circumferential surface of the through hole while the workpiece is pressed against the sliding portion, the sliding portion can slide reliably along the inner circumferential surface of the through hole, which allows the elongated member to be held more stably and reliably reduces the load acting on the elongated member as the workpiece moves.

[0015] In another aspect of the present invention, both the extension piece and the spacing portion may have the sliding portion. According to this invention, the sliding portions of the extension piece and the spacing portion can abut and slide against the inner circumferential surface of the through hole from both sides along the insertion direction. This allows the fixing member to more stably hold the elongated member on the workpiece and slide more smoothly, allowing the angle of the holding member to change more smoothly in response to external forces acting on the elongated member. Therefore, the load acting on the elongated member as the workpiece moves can be reliably reduced.

[0016] As another aspect of the present invention, the extension pieces may be arranged evenly in a circumferential direction around the insertion axis when viewed from the insertion direction. According to this invention, the sliding portions provided on each of the multiple extension pieces are able to evenly abut against the inner circumferential surface of the through hole and slide along the inner circumferential surface of the through hole. This allows the holder to be attached and fixed to the workpiece in a balanced manner, and the angle of the holder relative to the workpiece can be stably changed. Therefore, the elongated member can be stably attached, and the load acting on the elongated member as the workpiece moves can be more reliably reduced.

[0017] As another aspect of the present invention, the spacing portion may be formed of a plurality of support pieces that approach the insertion shaft as they extend in the insertion direction. According to this invention, the holding portion can be stably attached to the workpiece by using the plurality of extension pieces and support pieces to sandwich the workpiece along the insertion direction and support the workpiece from a direction intersecting the insertion direction. Therefore, the fixing member can more stably attach the elongated member to the workpiece.

[0018] As another aspect of the present invention, the support piece may be a biasing member that can bias in the insertion direction. According to this invention, the multiple extension pieces and support pieces can clamp the workpiece along the insertion direction while applying a biasing force, so that the holding portion can be attached to the workpiece more stably.

[0019] Furthermore, since the sliding portion can slide along the inner circumferential surface of the through hole while the extension piece and the support piece are elastically deformed as the workpiece moves, the sliding portion can slide more smoothly along the inner circumferential surface of the through hole, thereby reducing the load acting on the elongated member as the workpiece moves and more stably supporting the elongated member.

[0020] As another aspect of the present invention, the support pieces may be arranged evenly in a circumferential direction around the insertion axis when viewed from the insertion direction. According to this invention, multiple extension pieces and support pieces arranged evenly in the circumferential direction abut against the inner surface of the through hole in a balanced manner from both sides along the insertion direction, allowing the holding portion to be stably attached to the attached member.

[0021] Furthermore, because the sliding portions of the extension piece and the support piece abut evenly against the inner circumferential surface of the through hole in the circumferential direction, the resistance to the sliding portions caused by the movement of the workpiece is evenly distributed around the inner circumferential surface of the through hole. In other words, the angle of the holding portion relative to the workpiece can be changed with equal external forces in all directions. Therefore, the angle of the holding portion relative to the workpiece can be smoothly changed in response to the external forces acting on the elongated member as the workpiece moves, smoothly reducing the load acting on the elongated member.

[0022] In another aspect of the present invention, the support piece may be disposed at a position different from that of the extension piece when viewed from the insertion direction. According to this invention, the support piece and the extension piece are in uniform contact with the inner peripheral surface of the through hole when viewed from the insertion direction, so that the holding portion can be attached to the attached member more stably.

[0023] As another aspect of the present invention, the insertion shaft may have a rib along the insertion direction. According to this invention, the rigidity of the insertion shaft can be increased, so that the holding portion can be reliably fixed to the workpiece, and therefore the long member can be reliably held.

[0024] In another aspect of the present invention, the elongated member may be a wire harness, the holding portion may be formed in a rectangular plate shape that holds the wire harness, and a tape fixing portion for fixing the wire harness with tape may be provided at at least one end in the longitudinal direction.

[0025] According to this invention, the routing path of the wire harness held by the holding portion can be restricted, thereby preventing contact with surrounding components. Furthermore, when an external force acts on the elongated member due to movement of the workpiece, the angle of the holding portion relative to the workpiece can be appropriately changed, thereby suppressing bending and twisting of the wire harness fixed to the holding portion with tape. Therefore, the load acting on the wire harness can be reduced. [Effects of the Invention]

[0026] According to this invention, it is possible to provide a fixing member that can reduce the load acting on an elongated member attached to a workpiece when the workpiece moves. [Brief explanation of the drawings]

Figs. 8(a) and 8(b) correspond to part a in Fig. 6(a), and Figs. 9(a) and 9(b) correspond to part b in Fig. 6(b). For ease of explanation, Figs. 5 to 7 omit the wire harness WH.

[0033] 1, the direction along the long side of the harness holding portion 20 is the longitudinal direction X, the direction perpendicular to the longitudinal direction X and along the short side of the harness holding portion 20 is the width direction Y, and the up-down direction is the axial direction Z. In addition, in FIG. 1(a), the left side along the longitudinal direction X is the front side Xa, and the right side is the rear side Xb. Similarly, along the width direction Y, the left side is the left side Yb, and the right side is the right side Ya, and along the axial direction Z, the upper side is the insertion direction Za, and the lower side is the extraction direction Zb. The directions defined in FIG. 1 are the same in FIGS. 2 to 9.

[0034] The clamp 10 is a fixing member made of resin that holds the wire harness WH and attaches and fixes the wire harness WH to the door panel P. More specifically, as shown in FIG. 1 , the clamp 10 includes a harness holding portion 20 that holds the wire harness WH, and an anchor portion 30 that is inserted into an insertion hole P1 provided in the door panel P and fixed to the door panel P. The insertion hole P1 has a predetermined inner diameter and is formed to penetrate the door panel P. The inner peripheral surface of the insertion hole P1 is referred to as an inner peripheral surface P11 (see FIG. 2(b)).

[0035] The harness holding portion 20 is a holding member that holds the wire harness WH placed thereon by wrapping and fixing the wire harness WH with fixing tape T, and as shown in Figures 1(a) and 1(b), is integrally formed of a main body portion 21 formed in a plate shape and upright portions 22 that stand upright from both ends of the main body portion 21 in the longitudinal direction X toward the insertion direction Za.

[0036] The main body 21 is a plate-like body that is rectangular in plan view and has long sides along the longitudinal direction X. Here, the main surface of the main body 21 in the insertion direction Za is a fixing surface 211, and the main surface in the removal direction Zb is a holding surface 212.

[0037] The standing portion 22 prevents the fixing tape T from slipping out of the harness holding portion 20 when the fixing tape T is wound around the wire harness WH placed on the holding surface 212 to fix the wire harness WH.

[0038] The anchor portion 30 includes an insertion and fixing portion 40 that is inserted into the insertion hole P1 and fixed to the door panel P, and a spacing maintaining portion 50 that maintains a distance between the door panel P and the harness holding portion 20 in the insertion direction Za in which the insertion and fixing portion 40 is inserted when the clamp 10 is attached to the door panel P.

[0039] As shown in Figures 2(a) and 3, the insertion and fixing portion 40 is composed of a rod-shaped insertion shaft 41 that protrudes from the center of the fixing surface 211 in the longitudinal direction X and width direction Y toward the insertion direction Za, and a plurality of extension pieces 42 that extend radially from the end of the insertion shaft 41 on the insertion direction Za side.

[0040] The insertion shaft 41 is a generally circular shaft in plan view with a diameter smaller than the inner diameter of the insertion hole P1, and has three ribs 411 on its outer circumferential surface that are evenly spaced apart in the circumferential direction, as shown in FIG. 2(a). The rib 411 is provided from one end to the other end in the axial direction Z.

[0041] 2 and 3, the extension piece 42 extends from the end of the insertion shaft 41 on the insertion direction Za side, and is formed in a fan shape in plan view so that its width increases as it moves away from the insertion shaft 41. Such an extension piece 42 is composed of an upper extension piece 421 extending from the end of the insertion shaft 41 in the insertion direction Za, and a lower extension piece 422 extending from the end of the upper extension piece 421 on the removal direction Zb side.

[0042] 3(a) and 3(b), the upper extension piece 421 has a length about half that of the insertion shaft 41, and moves away from the insertion shaft 41 as it moves in the removal direction Zb. In addition, the upper extension piece 421 is formed so that the distance between the end of the upper extension piece 421 in the removal direction Zb and the insertion shaft 41 is larger than the radius of the insertion hole P1.

[0043] The lower extending piece 422 is formed to have a length about one-third that of the upper extending piece 421, and gradually approaches the insertion shaft 41 as it moves toward the extraction direction Zb. In other words, the lower extending piece 422 decreases in diameter and is formed with a cross-sectional arc that is convex toward the extraction direction Zb. The end of the lower extension piece 422 configured in this manner in the removal direction Zb is spaced apart from the outer circumferential surface of the insertion shaft 41. The outer circumferential surface of the lower extension piece 422 is defined as a first sliding surface 423.

[0044] The extension piece 42 is composed of an upper extension piece 421, one end of which is fixed to the insertion shaft 41, and a lower extension piece 422 that is continuous with the other end of the upper extension piece 421, and has elasticity because the other end of the lower extension piece 422 is a free end. The extension pieces 42 thus configured extend radially from the outer circumferential surface of the insertion shaft 41, three in total, at the center between the ribs 411 in the circumferential direction of the insertion shaft 41 (see FIG. 2(a)).

[0045] Here, for ease of explanation, the extension piece 42 located on the front side Xa and the right side Ya will be referred to as extension piece 42a, the extension piece 42 located on the front side Xa and the left side Yb will be referred to as extension piece 42b, and the extension piece 42 located on the rear side Xb will be referred to as extension piece 42c.

[0046] Next, the spacing member 50 will be described. The spacing retaining portion 50 is composed of three support pieces 51, and when the clamp 10 is attached to the door panel P, the support pieces 51 abut against the door panel P, thereby separating the door panel P and the harness retaining portion 20 in the axial direction Z and maintaining the spacing.

[0047] 3(b), in a plan view, the support piece 51 extends in the insertion direction Za from the circumferential outer side of the insertion shaft 41 on the fixing surface 211. More specifically, the support piece 51 extends in the insertion direction Za from a position spaced circumferentially outward from the center of the insertion shaft 41 beyond the inner diameter of the insertion hole P1.

[0048] The supporting piece 51 extending in this manner gradually approaches the insertion shaft 41 as it moves in the insertion direction Za. That is, the supporting piece 51 is formed to have a cross section that is convex in the insertion direction Za.

[0049] The support piece 51 is formed to have approximately the same length as the lower extension piece 422, and the end portion on the insertion direction Za side is spaced apart from the outer peripheral surface of the insertion shaft 41. Therefore, the support piece 51 has elasticity in the axial direction Z.

[0050] Furthermore, the end of the support piece 51 on the insertion direction Za side is located at a distance from the insertion axis 41 that is smaller than the radius of the insertion hole P1, and is positioned at approximately the same position in the axial direction Z as the end of the lower extension piece 422 on the removal direction Zb side. The outer peripheral surface of the support piece 51 configured in this manner serves as a second sliding surface 511 .

[0051] In plan view, three pieces 51 configured in this manner are disposed at equal intervals in the center between the extension pieces 42 in the circumferential direction of the insertion shaft 41 (see FIG. 2(a)). Here, for ease of explanation, the support piece 51 located on the front side Xa will be referred to as support piece 51a, the support piece 51 located on the rear side Xb and left side Yb will be referred to as support piece 51b, and the support piece 51 located on the rear side Xb and right side Ya will be referred to as support piece 51c.

[0052] Next, a method for attaching the clamp 10 configured as described above to the door panel P will be described. First, as shown in Fig. 4(a), the wire harness WH is placed on the holding surface 212 so as to be aligned with the longitudinal direction X of the clamp 10. Then, the fixing tape T is wound around both end portions of the main body 21, i.e., the inside of the standing portion 22 in the longitudinal direction X, to fix and hold the wire harness WH to the harness holding portion 20 (see Fig. 4(b)).

[0053] Next, the anchor portion 30 of the clamp 10 is placed opposite the insertion hole P1 in the axial direction Z, and the anchor portion 30 is inserted into the insertion hole P1 by being pushed in the insertion direction Za. Here, the ends of the three lower extending pieces 422 in the removal direction Zb are not constrained, so by pushing the anchor part 30 into the insertion hole P1, the extending pieces 42 are elastically deformed so as to approach the insertion shaft 41, as shown in Figures 5(a) and 5(b). This allows the anchor part 30 to be gradually inserted into the insertion hole P1.

[0054] Then, when the anchor part 30 is further pushed in, the end part of the upper extension piece 421 in the removal direction Zb passes through the insertion hole P1. At this time, as shown in Figures 6(a) and 6(b), the first sliding surface 423 of the extension piece 42 abuts against the edge part of the inner circumferential surface P11 of the insertion hole P1 on the insertion direction Za side. Also, the second sliding surface 511 of the support piece 51 abuts against the edge part of the inner circumferential surface P11 on the removal direction Zb side.

[0055] Furthermore, because the extension piece 42 is pressed in a direction approaching the insertion shaft 41, a restoring force acts in a direction away from the insertion shaft 41. That is, a biasing force F1 acts on the lower extension piece 422. Therefore, the lower extension piece 422 is biased toward the spacing retaining portion 50 (see FIGS. 6(a) and 8(a)).

[0056] Similarly, the support piece 51 is also pressed in a direction approaching the insertion shaft 41, and therefore a restoring force acts in a direction away from the insertion shaft 41, and a biasing force F2 acts on the support piece 51 (see FIGS. 6(b) and 9(a)). That is, the support piece 51 biases the support piece 51 toward the insertion and fixing portion 40.

[0057] As a result, the clamp 10 can clamp the door panel P in the axial direction Z while applying the biasing forces F1 and F2 between the first sliding surface 423 and the second sliding surface 511. Therefore, the clamp 10 can stably attach the wire harness WH held by the harness holding portion 20 to the door panel P.

[0058] As shown in Figures 6(a) and 8(a), the point where the first sliding surface 423 of the extension piece 42a abuts against the inner surface P11 is referred to as contact portion T1, and as shown in Figures 6(b) and 9(a), the point where the second sliding surface 511 of the support piece 51c abuts against the inner surface P11 is referred to as contact portion T2.

[0059] As described above, the harness holding portion 20 fixed to the door panel P can change its angle with respect to the door panel P when an external force acts on the wire harness WH that it holds. For example, when the door panel P is opened or closed, an external force acts on the wire harness WH in the forward direction Xa and the withdrawal direction Zb. At this time, the harness holding portion 20 is pulled in the forward direction Xa and the withdrawal direction Zb by the external force acting on the wire harness WH, and is thereby tilted.

[0060] As a result, the extension piece 42a slides along the inner circumferential surface P11 of the insertion hole P1 while the first sliding surface 423 of the extension piece 42a abuts against the edge portion of the inner circumferential surface P11 of the insertion hole P1 on the insertion direction Za side. That is, the contact portion moves along the first sliding surface 423 from the contact portion T1 to the contact portion T1' in the insertion direction Za (see FIGS. 8(a) and 8(b)).

[0061] Here, the extension piece 42a has an arc-shaped cross section that convexly extends toward the support piece 51, and therefore can smoothly slide along the inner circumferential surface P11 of the insertion hole P1. Furthermore, because the extension piece 42a is pressed toward the insertion shaft 41, a restoring force acts on the extension piece 42a in a direction away from the insertion shaft 41. That is, a biasing force F3 acts on the lower extension piece 422 (see FIG. 8(b)). Therefore, the extension piece 42a can be pressed against the door panel P so that the first sliding surface 423 abuts against the inner circumferential surface P11, and the extension piece 42a can reliably slide along the inner circumferential surface P11 of the insertion hole P1.

[0062] 7(b), the second sliding surface 511 of the support piece 51c slides along the inner circumferential surface P11 of the insertion hole P1 while abutting against an edge portion of the inner circumferential surface P11 of the insertion hole P1 on the side of the removal direction Zb. That is, the contact portion moves along the second sliding surface 511 from contact portion T2 to contact portion T2' in the removal direction Zb (see FIGS. 9(a) and 9(b)).

[0063] Here, the support piece 51c has an arc-shaped cross section that is convex toward the extension piece 42, and therefore can slide smoothly along the inner circumferential surface P11 of the insertion hole P1. Furthermore, because the support piece 51c is pressed in a direction approaching the insertion shaft 41, a restoring force acts in a direction away from the insertion shaft 41. In other words, a biasing force F4 is acting (see FIG. 9(b)). Therefore, the support piece 51c can be pressed against the door panel P so that the second sliding surface 511 abuts against the inner circumferential surface P11, and the support piece 51c can be reliably slid along the inner circumferential surface P11 of the insertion hole P1.

[0064] As described above, even when the angle of the clamp 10 changes, the first sliding surface 423 and the second sliding surface 511 can sandwich and slide the door panel P along the axial direction Z while applying the biasing forces F3 and F4. Therefore, the clamp 10 can more stably support the wire harness WH while reducing the load acting on the wire harness WH.

[0065] The clamp 10 configured in this manner includes a harness holding portion 20 that holds the wire harness WH to be attached to the door panel P, an insertion and fixing portion 40 that is inserted into an insertion hole P1 provided in the door panel P and fixed to the door panel P, and a spacing holding portion 50 that, when attached to and fixed to the door panel P, maintains a gap between the door panel P and the harness holding portion 20 by separating them in the insertion direction Za in which the insertion and fixing portion 40 is inserted into the insertion hole P1. The insertion fixing portion 40 is provided with an insertion shaft 41 that is inserted into the insertion hole P1, and a plurality of extension pieces 42 that extend from the insertion shaft 41 so as to move away from the insertion shaft 41 as it moves toward the removal direction Zb, and both the extension pieces 42 and the spacing retaining portion 50 have lower extension pieces 422 and support pieces 51 that reduce in diameter as they move toward each other along the insertion direction Za, and in the fixed state abut against the inner surface P11 of the insertion hole P1 and slide along the inner surface P11 as they move relative to the door panel P. The clamp-equipped wire harness 1 includes a wire harness WH to be attached to the door panel P and a clamp 10, and the wire harness WH is held by a harness holding portion 20.

[0066] This reduces the load acting on the wire harness WH attached to the door panel P due to the movement of the door panel P. In more detail, the door panel P is provided with an insertion shaft 41 that is inserted into an insertion hole P1 provided in the door panel P, an insertion fixing portion 40 that has an extension piece 42 extending from the insertion shaft 41, and a spacing retaining portion 50, so that the harness retaining portion 20 that holds the wire harness WH can be attached and fixed to the door panel P with a gap in the insertion direction Za relative to the door panel P.

[0067] Furthermore, since both the extension piece 42 and the spacing retaining portion 50 have the lower extension piece 422 and the support piece 51 that abut and slide against the inner circumferential surface P11 of the insertion hole P1, the lower extension piece 422 and the support piece 51 can be slid along the inner circumferential surface P11 of the insertion hole P1, thereby changing the angle of the harness holding portion 20 with respect to the door panel P. Therefore, when an external force acts on the wire harness WH as the door panel P moves, the clamp 10 can appropriately change the angle of the harness holding portion 20 with respect to the door panel P, thereby reducing the load on the wire harness WH held by the harness holding portion 20.

[0068] As described above, the extension piece 42 has the lower extension piece 422, and the spacing retaining portion 50 has the support piece 51. As a result, the lower extension piece 422 and the support piece 51 of the extension piece 42 and the spacing retaining portion 50 can abut and slide against the inner circumferential surface P11 of the insertion hole P1 from both sides along the axial direction Z. This allows the clamp 10 to more stably hold the wire harness WH on the door panel P, slide more smoothly, and change the angle of the harness retaining portion 20 more smoothly in response to an external force acting on the wire harness WH. This reliably reduces the load acting on the wire harness WH as the door panel P moves.

[0069] Furthermore, the lower extension piece 422 and the support piece 51 have arcuate cross sections that are convex in the opposing directions, allowing the lower extension piece 422 and the support piece 51 to slide smoothly along the inner circumferential surface P11 of the insertion hole P1. This allows the angle of the clamp 10 to be smoothly changed in response to an external force acting on the wire harness WH. This allows the lower extension piece 422 and the support piece 51 to slide along the inner circumferential surface P11 of the insertion hole P1 in accordance with the movement of the door panel P.

[0070] Moreover, the extension piece 42 and the spacing retaining portion 50 are biasing members that can bias in directions opposite to each other along the axial direction Z. As a result, in the fixed state, the door panel P can be sandwiched between the extension piece 42 and the spacing retaining portion 50 while applying the biasing forces F1 and F2, so that the harness retaining portion 20 can be stably attached to the door panel P.

[0071] Furthermore, since the lower extension piece 422 and the support piece 51 can be slid along the inner peripheral surface P11 of the insertion hole P1 with the door panel P pressed against the lower extension piece 422 and the support piece 51, the lower extension piece 422 and the support piece 51 can be reliably slid along the inner peripheral surface P11 of the insertion hole P1. Therefore, the wire harness WH can be more stably held, and the load acting on the wire harness WH due to movement of the door panel P can be reliably reduced.

[0072] The extension pieces 42 are arranged evenly in the circumferential direction around the insertion shaft 41 as the center when viewed from the insertion direction Za. According to this, the lower extension pieces 422 provided on each of the plurality of extension pieces 42 are evenly abutted against the inner peripheral surface P11 of the insertion hole P1 and can slide along the inner peripheral surface P11 of the insertion hole P1. This allows the harness holding portion 20 to be attached and fixed to the door panel P in a well-balanced manner and also allows the angle of the harness holding portion 20 with respect to the door panel P to be stably changed. Therefore, the wire harness WH can be stably attached and the load acting on the wire harness WH as the door panel P moves can be more reliably reduced.

[0073] The spacing portion 50 is made up of a plurality of support pieces 51 that come closer to the insertion shaft 41 as they move in the insertion direction Za. According to this, the door panel P can be clamped along the axial direction Z using the multiple extension pieces 42 and the support pieces 51, and can also be supported from a direction intersecting the axial direction Z, so that the harness holding portion 20 can be stably attached to the door panel P. Therefore, the clamp 10 can attach the wire harness WH to the door panel P more stably.

[0074] Furthermore, as viewed from the insertion direction Za, the support pieces 51 are evenly arranged circumferentially around the insertion shaft 41, and therefore can abut against the inner peripheral surface P11 of the insertion hole P1 in a balanced manner from both sides along the axial direction Z. This allows the harness holding portion 20 to be stably attached to the door panel P.

[0075] Furthermore, since the lower extending piece 422 and the support piece 51 provided on the extending piece 42 and the support piece 51 abut evenly in the circumferential direction against the inner circumferential surface P11 of the insertion hole P1, the resistance to the lower extending piece 422 and the support piece 51 caused by the movement of the door panel P is evenly distributed in the circumferential direction of the inner circumferential surface P11 of the insertion hole P1. In other words, the angle of the harness holding portion 20 with respect to the door panel P can be changed with equal external forces in all directions. Therefore, the angle of the harness holding portion 20 with respect to the door panel P can be smoothly changed in accordance with the external force acting on the wire harness WH with the movement of the door panel P, and the load acting on the wire harness WH can be smoothly reduced.

[0076] Furthermore, the support piece 51 is disposed at a different position from the extending piece 42 when viewed from the insertion direction Za, and therefore the support piece 51 and the extending piece 42 are in uniform contact with the inner circumferential surface P11 of the insertion hole P1 when viewed from the axial direction Z. This allows the harness holding portion 20 to be attached to the door panel P more stably.

[0077] Furthermore, the insertion shaft 41 has the rib 411 along the axial direction Z, which increases the rigidity of the insertion shaft 41, thereby enabling the harness holding portion 20 to be reliably fixed to the door panel P. Therefore, the wire harness WH can be reliably held.

[0078] The long member is a wire harness WH, and the harness holding portion 20 is formed in a rectangular plate shape to hold the wire harness WH, and at least one end in the longitudinal direction X is provided with an upright portion 22 for fixing the wire harness WH with tape.

[0079] This makes it possible to regulate the routing path of the wire harness WH held by the harness holding portion 20, thereby preventing contact with surrounding components. Furthermore, when an external force acts on the wire harness WH as the door panel P moves, the angle of the harness holding portion 20 with respect to the door panel P can be appropriately changed, thereby suppressing bending and twisting of the wire harness WH fixed by tape to the harness holding portion 20. Therefore, the load acting on the wire harness WH can be reduced.

[0080] In correspondence between the configuration of this invention and the above-mentioned embodiment, The mounting member of the present invention corresponds to the door panel P of the embodiment, Similarly, The long parts are compatible with the wire harness WH. The holding portion corresponds to the harness holding portion 20, The through hole corresponds to the insertion hole P1, The insertion and fixing portion corresponds to the insertion and fixing portion 40, The insertion direction corresponds to the insertion direction Za, The spacing portion corresponds to the spacing portion 50, The insertion shaft corresponds to the insertion shaft 41, The extension piece corresponds to the extension piece 42, The inner peripheral surface corresponds to the inner peripheral surface P11, The sliding portion corresponds to the lower extension piece 422 and the support piece 51, The fixing member corresponds to the clamp 10, The support piece corresponds to the support piece 51, The rib corresponds to rib 411, The wire harness is compatible with the WH wire harness. The longitudinal direction corresponds to the longitudinal direction X, The tape fixing portion corresponds to the standing portion 22, The wire harness with a fixing member corresponds to the clamp-equipped wire harness 1, but the present invention is not limited to the configuration of the above-described embodiment, and many other embodiments can be obtained.

[0081] For example, in the above-described embodiment, both the extension piece 42 and the spacing retaining portion 50 are provided with the lower extension piece 422 and the support piece 51, and the spacing retaining portion 50 also has the biasing force F2, but this is not limiting. For example, the extension piece 42 may have the lower extension piece 422, which is a biasing member, and the spacing retaining portion 50 may be configured, for example, as a hemisphere that is convex toward the extension piece 42, which does not have a biasing force, instead of the multiple support pieces 51. Even with this clamp 10, the angle can be changed while fixing the wire harness WH to the door panel P.

[0082] Furthermore, for example, the extension piece 42 may have the first sliding surface 423, and may be configured as an umbrella-shaped biasing member that moves away from the insertion shaft 41 as the spacing retaining portion 50 moves toward the insertion direction Za. That is, only the extension piece 42 may have a sliding portion, and the spacing retaining portion 50 may be configured as a biasing member that does not have a sliding portion. Even with such a clamp 10, the angle can be changed while fixing the wire harness WH to the door panel P.

[0083] Furthermore, the extending piece 42 may be a biasing member shaped to move away from the insertion shaft 41 as it moves toward the removal direction Zb, and the support piece 51 may be provided only on the spacing portion 50. In other words, only the support piece 51 may have a sliding portion, and the extending piece 42 may be a biasing member that does not have a pivot portion. In the above-described configuration, the spacing portion 50 may or may not be a biasing member.

[0084] In the above-described embodiment, the door panel P is used as a member that moves relative to the main body 21 that holds the wire harness WH, but this is not limiting. For example, instead of the door panel P, a sliding seat that moves in the front-to-rear direction of the vehicle, an electrical connection box that is affected by vehicle vibrations, etc. may also be used.

[0085] In the above-described embodiment, the harness holding portion 20 holds the wire harness WH, but it is not limited to the wire harness WH, and may include, for example, a communication cable for communicating between the mounted devices, a tube arranged along a desired routing path, etc.

[0086] In the above-described embodiment, the harness holding portion 20 is a flat plate capable of holding the wire harness WH, but is not limited to this. For example, the harness holding portion 20 may have a band structure that is wound around the outer periphery of the wire harness WH to hold the wire harness WH, or a through structure or other structure that holds a connector provided at the end of the wire harness WH.

[0087] Furthermore, the erected portions 22 are configured to be provided at both ends of the fixing surface 211 in the longitudinal direction X, but the erected portion 22 may be provided at one end and the wire harness WH may be fixed with tape at only one end. [Explanation of symbols]
