DETAILED DESCRIPTION OF THE INVENTION

[0010] Modes (embodiments) for carrying out the present invention will be described in detail with reference to the drawings. The present invention is not limited to the contents described in the following embodiments. Furthermore, the components described below include those that can be easily imagined by a person skilled in the art and those that are substantially the same. Furthermore, the configurations described below can be combined as appropriate. Furthermore, various omissions, substitutions, or modifications of the configuration can be made within the scope of the gist of the present invention.

[0011] [Embodiment] A band clip 1 and a wire harness WH according to an embodiment will be described with reference to the drawings. The wire harness WH is, for example, a component in which a plurality of wiring materials W used for power supply and signal communication are bundled together to connect various devices mounted on a vehicle, and the wiring materials W are connected to the various devices using connectors or the like. The wire harness WH is configured to include, but is not limited to, wiring materials W, a protector, an exterior material, a fastener, and the like. In this example, an example will be described in which the wire harness WH includes a conductive wiring material W and a band clip 1 that is fastened to an attachment object B (see FIG. 3) in a bundled state of the wiring material W. The wiring material W is, for example, configured of a metal rod, an electric wire, an electric wire bundle, etc. The metal rod is a conductive rod-shaped member whose outer surface is covered with an insulating coating. The electric wire is a conductor portion (core wire) made of a plurality of conductive metal wires whose outer surface is covered with an insulating coating. The electric wire bundle is a bundle of such electric wires. The attachment object B to which the band clip 1 is attached is, for example, a metal or resin panel member provided on a vehicle. The attachment object B has a through-hole, and the clip portion 20 of the band clip 1 (described later) is inserted into the through-hole to be attached.

[0012] In the following description, of the first, second, and third directions that intersect with one another, the first direction will be referred to as the "extension direction X," the second direction will be referred to as the "width direction Y," and the third direction will be referred to as the "thickness direction Z." The extension direction X, width direction Y, and thickness direction Z intersect with one another and are typically perpendicular to one another. The extension direction X is, for example, the direction in which the groove portion 31 of the band fixing portion 30 described below extends. The width direction Y is the direction along the width of the groove portion 31 of the band fixing portion 30, and can also be said to be the direction along the direction in which the wiring material W extends. The thickness direction Z is the direction along the depth of the groove portion 31 of the band fixing portion 30. Unless otherwise specified, the directions used in the following description represent the directions when the parts are assembled together.

[0013] The wire harness WH according to the embodiment includes a wiring material W and a band clip 1, as shown in FIGS.

[0014] The band clip 1 is used to fasten a bundled wiring material W to an attachment object B such as a panel member. The band clip 1 is formed from a material such as synthetic resin, and includes a main body portion 10, a clip portion 20, a band fixing portion 30, and a band portion 40.

[0015] The main body 10 is the base of the band clip 1 and has an external shape formed in a rectangular parallelepiped. The main body 10 extends, for example, along the width direction Y and has a predetermined thickness along the thickness direction Z. The main body 10 has a recess 11 recessed along the thickness direction Z at the center in the width direction Y, and the clip portion 20 is provided in this recess 11. Furthermore, the main body 10 has a band fixing portion 30A on one side in the width direction Y and a band fixing portion 30B on the other side in the width direction Y.

[0016] Next, a description will be given of the clip portion 20. The clip portion 20 is a portion that is engaged with the attachment object B. The clip portion 20 is configured to include a support post 21, a skirt portion 22, and a pair of clip pieces 23.

[0017] The support pillar 21 supports the skirt portion 22 and the pair of clip pieces 23. The support pillar 21 is formed in a columnar shape and extends from the main body 10 along the thickness direction Z toward the attachment object B. The skirt portion 22 and the pair of clip pieces 23 are fixed to the support pillar 21.

[0018] The skirt portion 22 supports the attachment object B from below in the thickness direction Z. The skirt portion 22 is an elastically deformable member, and is formed, for example, in an elliptical shape when viewed from the thickness direction Z, and in a dish shape recessed toward the main body portion 10 along the thickness direction Z. The skirt portion 22 is formed so that the support pillar 21 is located in the center of the skirt portion 22 and extends around the support pillar 21.

[0019] The pair of clip pieces 23 are engaged with the attachment object B and are configured to be elastically deformable. For example, one end of the pair of clip pieces 23 is fixed in a cantilevered manner to the upper side of the support column 21 in the thickness direction Z, and the other end is configured as a free end, and is formed so as to expand in the width direction Y from one end side to the other end side. When the pair of clip pieces 23 is inserted into the through hole of the attachment object B, it is compressed in the width direction Y to match the diameter of the through hole, and after compression, it returns to its original shape by coming out of the through hole of the attachment object B. At this time, the pair of clip pieces 23 are engaged with the attachment object B with the attachment object B sandwiched between the pair of clip pieces 23 and the skirt portion 22.

[0020] Next, the band fixing portion 30 will be described. The band fixing portion 30 fixes the band portion 40. The band fixing portions 30 are provided on each of the main body portions 10, one on each side of the clip portion 20 in the width direction Y, and are connected to the clip portion 20 via the main body portion 10. The band fixing portion 30 is configured to include a band fixing portion 30A and a band fixing portion 30B, with the band fixing portion 30A being provided on one side of the main body portion 10 in the width direction Y and the band fixing portion 30B being provided on the other side of the main body portion 10 in the width direction Y, with the clip portion 20 being between them. Because the band fixing portion 30A and the band fixing portion 30B have the same configuration, hereinafter, when there is no need to distinguish between the band fixing portion 30A and the band fixing portion 30B, they will be described as the band fixing portion 30.

[0021] As shown in FIG. 5 and other figures, the band fixing part 30 includes a groove part 31, a recessed part 32, and at least one pair of locking projections 33.

[0022] The groove 31 is for fitting the band portion 40. The groove 31 is provided on the attachment target B side of the main body 10, and is formed in a groove shape along the extension direction X of the main body 10. The groove 31 has, for example, a certain depth in the thickness direction Z, and has an accommodation space inside. The tip 411 side of the band portion 40 wound around the routing material W is fitted into the groove 31, and the tip 411 side of the band portion 40 is accommodated in the accommodation space. Because the length of the groove 31 in the extension direction X is shorter than the length of the band portion 40 in the extension direction X, a part of the tip 411 side of the band portion 40 is fitted into the groove 31, and a part of the tip 411 side of the band portion 40 is accommodated in the accommodation space.

[0023] As shown in Fig. 6, the pair of recesses 32 hold the band portion 40 housed in the groove portion 31 and prevent the band portion 40 housed in the groove portion 31 from slipping out of the groove portion 31. The pair of recesses 32 are formed, for example, in recessed shapes along the width direction Y on both sides of the groove portion 31 in the width direction Y, and each house a locking projection 42 of the band portion 40. The pair of recesses 32 is composed of a recess 32 on one side and a recess 32 on the other side in the width direction Y.

[0024] The recess 32 on one side is composed of a bottom wall 321 located at the bottom of the groove 31, a side wall 322 standing along the thickness direction Z from one side of the bottom wall 321 in the width direction Y, and a protruding wall 323 protruding from the side wall 322 along the width direction Y to prevent the engagement projection 42 housed in the recess 32 on one side from coming out. The recess 32 on the other side is composed in the same manner as the recess 32 on the one side described above. That is, the recess 32 on the other side is composed of the bottom wall 321 located at the bottom of the groove 31, a side wall 322 standing along the thickness direction Z from the other side of the bottom wall 321 in the width direction Y, and a protruding wall 323 protruding from the side wall 322 along the width direction Y to prevent the engagement projection 42 housed in the recess 32 on the other side from coming out.

[0025] Each of the protruding walls 323 includes a first inclined surface 323a, a second inclined surface 323b, and a third inclined surface 323c in a cross section along the width direction Y and the thickness direction Z.

[0026] The first inclined surface 323a is provided on the side of the protruding wall portion 323 opposite to the bottom wall portion 321 side in the thickness direction Z, and is inclined toward the bottom wall portion 321 side in the width direction Y from the base end 323d side toward the tip end 323e side of the protruding wall portion 323. In other words, the first inclined surface 323a is inclined toward the bottom wall portion 321 side with respect to an imaginary plane E2 along the width direction Y and the extension direction X from the base end 323d side toward the tip end 323e side of the protruding wall portion 323.

[0027] The second inclined surface 323b is provided on the bottom wall portion 321 side of the protruding wall portion 323 in the thickness direction Z, and is inclined from the base end 323d side toward the tip 323e side of the protruding wall portion 323 in the width direction Y toward the opposite side to the bottom wall portion 321 side. In other words, the second inclined surface 323b is inclined from the base end 323d side toward the tip 323e side of the protruding wall portion 323 in the opposite side to the bottom wall portion 321 side with respect to the imaginary plane E2.

[0028] The third inclined surface 323c is provided continuously with the second inclined surface 323b, and is inclined from the second inclined surface 323b side toward the base end 323d side of the protruding wall portion 323 in the opposite direction to the bottom wall portion 321 side with respect to the width direction Y. In other words, the third inclined surface 323c is inclined from the second inclined surface 323b side toward the base end 323d side of the protruding wall portion 323 in the opposite direction to the bottom wall portion 321 side with respect to the imaginary plane E2.

[0029] Each pair of locking protrusions 33 locks the locked protrusion 42 of the band portion 40. As shown in FIG. 5 , each locking protrusion 33 is provided in each recess 32 so as to protrude in the width direction Y. For example, each locking protrusion 33 protrudes inward in each recess 32 along the width direction Y, in other words, protrudes toward each other. Furthermore, the locking protrusion 33 on one side protrudes toward the locking protrusion 33 on the other side in the width direction Y in the recess 32, and the locking protrusion 33 on the other side protrudes toward the locking protrusion 33 on the one side in the width direction Y in the recess 32. The pair of locking protrusions 33 are positioned side by side in the width direction Y. Each locking protrusion 33 includes an abutting surface 331 and a locking surface 332.

[0030] The abutment surface 331 is formed so as to be inclined from the base end 333 side of the locking projection 33 toward the tip 334 side toward the tip 411 side of the band portion 40 with respect to the width direction Y. In other words, the abutment surface 331 is formed so as to be inclined from the base end 333 side toward the tip 334 side of the locking projection 33 toward the tip 411 side of the band portion 40 with respect to an imaginary plane E1 along the width direction Y and the thickness direction Z. Moreover, the abutment surface 331 is formed so that the amount of protrusion in the width direction Y increases from the base end 412 side toward the tip 411 side of the band portion 40. Furthermore, the angle formed by the abutment surface 331 and the extending direction X (the angle on the tip 411 side) is an acute angle. Since the abutment surface 331 is formed at an incline as described above, when the band portion 40 fitted into the groove portion 31 is pulled out toward the tip 411 of the band portion 40, it abuts against the climbing surface 421 of the engaging protrusion 42, allowing the engaging protrusion 42 to climb over the engaging protrusion 33.

[0031] The locking surface 332 is engaged with the locked surface 422 of the locked projection 42. The locking surface 332 is provided on the opposite side of the abutment surface 331 in the extension direction X, and is formed so as to be inclined from the base end 333 side of the locking projection 33 toward the tip 334 side thereof toward the tip 411 side of the band portion 40 with respect to the width direction Y. In other words, the locking surface 332 is formed so as to be inclined from the base end 333 side of the locking projection 33 toward the tip 334 side thereof toward the tip 411 side of the band portion 40 with respect to the imaginary plane E1. Furthermore, the locking surface 332 is formed so that the amount of protrusion in the width direction Y increases from the base end 412 side of the band portion 40 toward the tip 411 side thereof. Furthermore, the angle formed by the locking surface 332 and the extension direction X (the angle on the tip 411 side) is an acute angle. The locking surface 332 is formed with a greater inclination than the abutting surface 331. In other words, the abutting surface 331 is formed with a smaller inclination than the locking surface 332, and has a gentler inclination than the locking surface 332. In other words, the angle formed between the abutting surface 331 and the extension direction X (the angle on the tip 411 side) is smaller than the angle formed between the locking surface 332 and the extension direction X (the angle on the tip 411 side). The locking surface 332 locks the locked surface 422 of the locked protrusion 42 of the band portion 40 when the wiring material W is held by the band portion 40.

[0032] Next, the band portion 40 will be described. The band portion 40 is used to bind the wiring material W. The band portion 40 extends in a strip shape from the band fixing portion 30 and is engaged with the band fixing portion 30 while binding the wiring material W. One band portion 40 is provided on each of the main body portions 10, sandwiching the clip portion 20 in the width direction Y. The band portion 40 is configured to include a band portion 40A and a band portion 40B, with the band portion 40A being provided on one side of the main body portion 10 in the width direction Y and the band portion 40B being provided on the other side of the main body portion 10 in the width direction Y, sandwiching the clip portion 20. Since the band portion 40A and the band portion 40B have the same configuration, hereinafter, when there is no need to distinguish between the band portion 40A and the band portion 40B, they will be described as the band portion 40.

[0033] The band portion 40 includes a band body 41 and a plurality of pairs of engagement projections 42 .

[0034] The band body 41 is formed in a band shape, and as shown in FIG. 3, a base end 412 is connected to the band fixing part 30, and a tip end 411 is formed as a free end.

[0035] The plurality of pairs of locking projections 42 are engaged with the band fixing portion 30. Each locking projection 42 is located closer to the tip 411 than to the base end 412 of the band body 41, and protrudes from both sides of the band body 41 in the width direction Y. For example, each locking projection 42 protrudes outward from the band body 41 in the width direction Y, in other words, protrudes in directions away from each other. Furthermore, the locking projection 42 on one side protrudes from the band body 41 in the width direction Y to the side opposite the locking projection 42 on the other side, and the locking projection 42 on the other side protrudes from the band body 41 in the width direction Y to the side opposite the locking projection 42 on one side. The pair of locking projections 42 are positioned side by side in the width direction Y.

[0036] The locked projection 42 includes a climbing surface 421 , a locked surface 422 , and a curved surface 423 .

[0037] The climbing surface 421 is formed so as to be inclined from the base end 424 side of the locked projection 42 toward the tip 425 side toward the base end 412 side of the band portion 40 with respect to the width direction Y. In other words, the climbing surface 421 is formed so as to be inclined from the base end 424 side of the locked projection 42 toward the tip 425 side toward the base end 412 side of the band portion 40 with respect to the imaginary plane E1. Moreover, the climbing surface 421 is formed so that the amount of protrusion in the width direction Y increases from the tip 411 side of the band portion 40 toward the base end 412 side. Furthermore, the angle formed by the climbing surface 421 and the direction in which the band portion 40 extends (the angle on the base end 412 side) is an acute angle. Since the climbing surface 421 is formed at an incline as described above, when the band portion 40 fitted into the groove portion 31 is pulled out toward the tip 411 of the band portion 40, it comes into contact with the abutment surface 331 of the locking protrusion 33 and can climb over the locking protrusion 33.

[0038] The locked surface 422 is engaged with the locking surface 332 of the locking projection 33. The locked surface 422 is provided on the opposite side of the overriding surface 421 in the direction in which the band portion 40 extends, and is formed so as to be inclined from the base end 424 side of the locked projection 42 toward the tip 425 side thereof toward the base end 412 side of the band portion 40 with respect to the width direction Y. In other words, the locked surface 422 is formed so as to be inclined from the base end 424 side of the locked projection 42 toward the tip 425 side thereof toward the base end 412 side of the band portion 40 with respect to the imaginary plane E1. Furthermore, the locked surface 422 is formed so that the amount of protrusion in the width direction Y increases from the tip 411 side of the band portion 40 toward the base end 412 side thereof. Furthermore, the angle formed by the locked surface 422 and the direction in which the band portion 40 extends (the angle on the base end 412 side) is an acute angle. The locked surface 422 is formed with a steeper inclination than the overriding surface 421. In other words, the overriding surface 421 is formed with a shallower inclination than the locked surface 422, and has a gentler inclination than the locked surface 422. In other words, the angle formed between the overriding surface 421 and the extending direction of the band portion 40 (the angle on the base end 412 side) is smaller than the angle formed between the locked surface 422 and the extending direction of the band portion 40 (the angle on the base end 412 side). The locked surface 422 is locked to the locking surface 332 of the locking protrusion 33 of the band fixing portion 30 when the routing material W is held by the band portion 40.

[0039] The warped surface 423 is a portion that is formed to be warped. For example, when the locked projection 42 is accommodated in the recess 32 of the groove portion 31, the warped surface 423 faces the third inclined surface 323c of the recess 32 in the thickness direction Z, and is formed to be warped toward the third inclined surface 323c. The warped surface 423 prevents the band portion 40 accommodated in the groove portion 31 from slipping out of the recess 32 of the groove portion 31 in the thickness direction Z.

[0040] Next, a method for bundling the wiring material W and fastening it to an attachment target B, such as a panel member, will be described. As shown in FIG. 1, an operator wraps the band portion 40 around the wiring material W, and then, as shown in FIGS. 7 and 8, fits the band portion 40 into the groove portion 31 of the band fixing portion 30. At this time, the operator presses the pairs of locking projections 42 provided on the band portion 40 into the groove portion 31 along the thickness direction Z while sliding them against the first inclined surfaces 323a on both sides of the groove portion 31. At this time, each locking projection 42 is pressed into the groove portion 31 while deforming along the inclination of the first inclined surfaces 323a on both sides. Then, each locking projection 42 is pressed into the groove portion 31 along the thickness direction Z, and when it passes through the portion where the opening of the groove portion 31 is narrowest in the width direction Y, it gradually returns to its original shape along the second inclined surfaces 323b on both sides of the groove portion 31. Each of the locked projections 42 is finally accommodated in the pair of recesses 32 of the groove 31 and completely returns to its original shape. At this time, the band portion 40 is accommodated in the pair of recesses 32 of the groove 31 and is prevented from slipping out of the groove 31 upward in the thickness direction Z by the pair of protruding wall portions 323. The worker binds the wiring material W with the band portion 40 by pulling the band portion 40 accommodated in the pair of recesses 32 of the groove 31 toward the tip 411. At this time, the locked projections 42 of the band portion 40 climb over the locking projections 33 of the band fixing portion 30 as the climbing surface 421 abuts against the abutment surface 331 of the locking projections 33. After the wiring material W is bound by the band portion 40, the engaging surface 422 of the engaging projection 42 of the band portion 40 is engaged with the engaging surface 332 of the engaging projection 33 of the band fixing portion 30, maintaining the state in which the wiring material W is bound by the band portion 40. After binding the wiring material W with the band portion 40, the worker engages the clip portion 20 with the attachment object B to lock the wiring material W to the attachment object B.

[0041] As described above, the band clip 1 according to the embodiment comprises the clip portion 20, the band fixing portion 30, and the band portion 40. The clip portion 20 is engaged with the attachment object B. The band fixing portion 30 is connected to the clip portion 20 in advance. The band portion 40 extends in a strip shape from the band fixing portion 30 and is engaged with the band fixing portion 30 while binding the routing material W. In this configuration, the band portion 40 includes a pair of engaging projections 42 that protrude from both sides in the width direction Y and are engaged with the band fixing portion 30. The band fixing portion 30 is configured to include a groove portion 31 formed in a groove shape along an extension direction X intersecting the width direction Y and into which the band portion 40 is fitted, a pair of recesses 32 formed in a recessed shape along the width direction Y on both sides of the groove portion 31 in the width direction Y and each accommodating an engaging protrusion 42, and a pair of engaging protrusions 33 protruding in the width direction Y from each recess 32 and each engaging the engaging protrusion 42.

[0042] With this configuration, the band clip 1 can lock the band portion 40 to the band fixing portion 30 with the pair of locking projections 42 of the band portion 40 and the pair of locking projections 33 of the band fixing portion 30 aligned along the width direction Y. This allows the band clip 1 to have a thinner band fixing portion 30 and a lower profile compared to conventional cases in which the locking projections of the band portion and the locking projections of the band fixing portion are aligned along the thickness direction Z. This allows the band clip 1 to be installed properly even in places with limited installation space.

[0043] In the band clip 1, the locked projection 42 includes a climbing-over surface 421 and a locked surface 422. The climbing-over surface 421 is formed inclined from the base end 424 side of the locked projection 42 toward the tip 425 side toward the base end 412 of the band portion 40 in the width direction Y, and is capable of coming into contact with the locking projection 33 and climbing over the locking projection 33 when the band portion 40 fitted in the groove portion 31 is pulled toward the tip 411 of the band portion 40. The locked surface 422 is provided on the opposite side to the climbing-over surface 421 in the direction in which the band portion 40 extends, and is formed inclined from the base end 424 side toward the tip 425 side of the locked projection 42 toward the base end 412 of the band portion 40 in the width direction Y, and is locked by the locking projection 33. With this configuration, the band clip 1 can smoothly tie and bind the wiring material W with the band portion 40 by pulling out the band portion 40 fitted into the groove portion 31 toward the tip 411 of the band portion 40, and can maintain the wiring material W in a bound state with the band portion 40.

[0044] In the band clip 1, the recess 32 is composed of a bottom wall 321 located at the bottom of the groove 31, a side wall 322 standing from one side of the bottom wall 321 in the width direction Y along a thickness direction Z intersecting the width direction Y and the extension direction X, and a protruding wall 323 protruding from the side wall 322 along the width direction Y to prevent the engagement projection 42 accommodated in the recess 32 from coming off. The protruding wall 323 is composed of a first inclined surface 323a, a second inclined surface 323b, and a third inclined surface 323c. In a cross section taken along the width direction Y and the thickness direction Z, the first inclined surface 323a is located on the opposite side of the protruding wall 323 from the bottom wall 321 side in the thickness direction Z, and is inclined from a base end 323d of the protruding wall 323 to a tip end 323e of the protruding wall 323 toward the bottom wall 321 with respect to the width direction Y. The second inclined surface 323b is provided on the bottom wall portion 321 side of the protruding wall portion 323 in the thickness direction Z, and is inclined from the base end 323d side of the protruding wall portion 323 toward the tip end 323e side in the opposite direction to the bottom wall portion 321 side in the width direction Y. The third inclined surface 323c is provided continuously with the second inclined surface 323b, and is inclined from the second inclined surface 323b side toward the base end 323d side of the protruding wall portion 323 in the width direction Y in the opposite direction to the bottom wall portion 321 side. The locked projection 42 faces the third inclined surface 323c in the thickness direction Z when accommodated in the recess 32, and includes a warped surface 423 formed to be warped toward the third inclined surface 323c side.

[0045] With this configuration, the band clip 1 can shorten the distance in the thickness direction Z of the portion where the opening of the groove portion 31 is narrowest due to the first inclined surface 323a and the second inclined surface 323b, so that when the band portion 40 is deformed to fit into the groove portion 31 along the thickness direction Z, the load on the band portion 40 can be reduced, improving workability during fitting. Also, the band clip 1 can hook the warped surface 423 of the locked protrusion 42 onto the third inclined surface 323c, so that the band portion 40 housed in the groove portion 31 can be prevented from slipping out of the groove portion 31 in the thickness direction Z.

[0046] In the band clip 1, one band fixing portion 30 (30A, 30B) and one band portion 40 (40A, 40B) are provided on either side of the clip portion 20 in the width direction Y. With this configuration, the band clip 1 can bind the wiring material W with the two band portions 40 (40A, 40B), thereby stably securing the wiring material W.

[0047] In the band clip 1, the band portion 40 includes multiple pairs of locking projections 42, and the band fixing portion 30 includes one pair of locking projections 33. With this configuration, the band clip 1 can bind wiring materials W of different diameters by selecting the locking projections 42 that are locked by the locking projections 33, thereby improving versatility. Furthermore, by providing multiple pairs of locking projections 42 on the band portion 40, the band clip 1 can widen the adjustment range of the diameter of the wiring material W compared to, for example, providing multiple pairs of locking projections 33 on the band fixing portion 30, thereby further improving versatility. In other words, when the band clip 1 has multiple sets of pairs of engaging protrusions 42 on the band portion 40, it can have a greater number of sets of pairs of engaging protrusions 42 than when it has multiple sets of pairs of engaging protrusions 33 on the band fixing portion 30, thereby making it possible to accommodate a wider range of diameters of wiring materials W.

[0048] The wire harness WH comprises a conductive wiring material W and a band clip 1 that is fastened to the attachment object B while the wiring material W is bound, so that the wiring material W can be properly wired by the low-profile band clip 1.

[0049] [Modification] In the above description, the locked protrusion 42 includes the overcoming surface 421 and the locked surface 422 formed at an incline with respect to the width direction Y, but is not limited to this. For example, the locked protrusion 42 may form a flat surface along the width direction Y without being inclined with respect to the width direction Y.

[0050] Although the protruding wall portion 323 has been described as including the first inclined surface 323a, the second inclined surface 323b, and the third inclined surface 323c that are formed so as to be inclined with respect to the width direction Y, the present invention is not limited to this. For example, the protruding wall portion 323 may form a flat surface portion along the width direction Y without being inclined with respect to the width direction Y.

[0051] Although the example in which the locked projection 42 includes the warped surface 423 formed so as to be warped toward the third inclined surface 323c has been described, the present invention is not limited to this, and for example, the warped surface 423 may be formed as a flat surface.

[0052] Although an example has been described in which one band fixing portion 30 (30A, 30B) and one band portion 40 (40A, 40B) are provided on either side of the clip portion 20 in the width direction Y, the present invention is not limited to this. For example, one band fixing portion 30 and one band portion 40 may be provided, or two or more of each may be provided.

[0053] Although an example has been described in which the band portion 40 includes multiple pairs of locking projections 42 and the band fixing portion 30 includes one pair of locking projections 33, the present invention is not limited to this. For example, the band portion 40 may include one pair of locking projections 42, and the band fixing portion 30 may include multiple pairs of locking projections 33. Furthermore, when the diameter of the wiring material W to be bundled is predetermined and there is only one pattern, the band portion 40 may include one pair of locking projections 42, and the band fixing portion 30 may include one pair of locking projections 33.
