Description

本発明は、ワイヤハーネスを被取付部材に固定するためのクランプ、及び、クランプ付きワイヤハーネスに関するものである。 The present invention relates to a clamp for fixing a wire harness to a member to be attached, and a wire harness with a clamp.

従来より、ワイヤハーネスを車体パネル等の被取付部材に固定するために、種々のクランプが用いられてきた。図７は、特許文献１に開示されたクランプの斜視図であり、図８は、図７のクランプを備えたクランプ付きワイヤハーネスが被取付部材に固定された状態を示す図である。 Conventionally, various clamps have been used to fix a wire harness to a member to be attached such as a vehicle body panel. FIG. 7 is a perspective view of the clamp disclosed in Patent Document 1, and FIG. 8 is a diagram showing a state in which a wire harness with a clamp provided with the clamp of FIG. 7 is fixed to a member to be attached.

図７，８に示されたクランプ３３１は、ワイヤハーネス３０４に沿わされる帯板状の基板部３０３と、被取付部材３００の孔３０１に圧入係止される係止部３０２と、係止部３０２の基端部周囲と被取付部材３００との隙間を塞ぐシール部３０８と、を備えている。係止部３０２及びシール部３０８は、基板部３０３の長手方向の中央部３３２に設けられている。クランプ３３１とワイヤハーネス３０４とは、中央部３３２の長手方向両外側部分とワイヤハーネス３０４とにビニールテープ３０５が巻き付けられることによって固定されている。 The clamps 331 shown in FIGS. 7 and 8 include a strip-shaped substrate portion 303 along the wire harness 304, a locking portion 302 that is press-fitted into the hole 301 of the attached member 300, and a locking portion. A seal portion 308 that closes a gap between the periphery of the base end portion of 302 and the attached member 300 is provided. The locking portion 302 and the sealing portion 308 are provided at the central portion 332 of the substrate portion 303 in the longitudinal direction. The clamp 331 and the wire harness 304 are fixed by wrapping vinyl tape 305 around both outer portions of the central portion 332 in the longitudinal direction and the wire harness 304.

また、クランプ３３１は、基板部３０３の中央部３３２（即ち係止部３０２の基端部の周縁部分）の曲げ強度を、この中央部３３２の長手方向両外側部分（即ちビニールテープ３０５が巻き付けられている部分）の曲げ強度よりも大きくするために、中央部３３２の厚みが、中央部３３２の長手方向両外側部分の厚みよりも大きく形成されている。 Further, the clamp 331 is wound with the bending strength of the central portion 332 of the substrate portion 303 (that is, the peripheral portion of the base end portion of the locking portion 302) on both outer portions in the longitudinal direction of the central portion 332 (that is, the vinyl tape 305). The thickness of the central portion 332 is formed to be larger than the thickness of both outer portions in the longitudinal direction of the central portion 332 in order to increase the bending strength of the central portion 332.

また、中央部３３２の長手方向両外側部分には、中央部３３２と同じ高さになるように、ワイヤハーネス３０４に当接する当接用リブ３３３が設けられている。当接用リブ３３３は、半円柱形状であり、基板部３０３の幅方向の全域にわたって設けられている。即ち、当接用リブ３３３は、テープ巻きされた中央部３３２の長手方向両外側部分とワイヤハーネス３０４との相対位置が変化することを規制するスペーサとして機能する。 Further, abutting ribs 333 that come into contact with the wire harness 304 are provided on both outer portions of the central portion 332 in the longitudinal direction so as to have the same height as the central portion 332. The contact rib 333 has a semi-cylindrical shape and is provided over the entire width direction of the substrate portion 303. That is, the abutting rib 333 functions as a spacer that regulates the relative position of the tape-wound central portion 332 on both outer sides in the longitudinal direction and the wire harness 304 from changing.

上述したクランプ３３１が取り付けられたワイヤハーネス３０４においては、被取付部材３００に固定された後、引き回し作業等によって図８に示すようにワイヤハーネス３０４に荷重がかかった状態になっても、中央部３３２の長手方向両外側部分（即ちビニールテープ３０５が巻き付けられている部分）が大きく撓んで、中央部３３２の撓み量を少なくすることができる。このことにより、ワイヤハーネス３０４に荷重がかかった状態になっても、シール部３０８と被取付部材３００との密着状態を維持することができ、防水性能の低下を防止することができる。 In the wire harness 304 to which the clamp 331 is attached as described above, even if a load is applied to the wire harness 304 as shown in FIG. 8 due to a routing operation or the like after being fixed to the attached member 300, the central portion thereof. Both outer portions of the 332 in the longitudinal direction (that is, the portion around which the vinyl tape 305 is wound) are greatly bent, and the amount of bending of the central portion 332 can be reduced. As a result, even when a load is applied to the wire harness 304, the state of close contact between the seal portion 308 and the attached member 300 can be maintained, and deterioration of the waterproof performance can be prevented.

上述したクランプ３３１が取り付けられたワイヤハーネス３０４においては、配索時にビニールテープ３０５の粘着力を上回る大きな引張力が及ぶと、クランプ３３１とワイヤハーネス３０４とが当該ワイヤハーネス３０４の長手方向に相対的にずれてしまうおそれがあるという問題があった。なお、当接用リブ３３３は、ワイヤハーネス３０４の外表面に当接しているものの、その表面が弧状であるため、ワイヤハーネス３０４に対し引っ掛かり作用が弱かった。 In the wire harness 304 to which the clamp 331 is attached as described above, when a large tensile force exceeding the adhesive force of the vinyl tape 305 is applied at the time of routing, the clamp 331 and the wire harness 304 are relative to the wire harness 304 in the longitudinal direction. There was a problem that there was a risk of shifting to. Although the abutting rib 333 is in contact with the outer surface of the wire harness 304, the surface thereof is arcuate, so that the abutting rib 333 has a weak catching action on the wire harness 304.

そこで、本発明は、ワイヤハーネスに引張力が及んでも、ワイヤハーネスとクランプとの相対的移動を抑制することができるクランプ、及び、該クランプ付きワイヤハーネスを提供することを目的とする。 Therefore, an object of the present invention is to provide a clamp capable of suppressing the relative movement between the wire harness and the clamp even when a tensile force is applied to the wire harness, and a wire harness with the clamp.

本発明のクランプは、帯板状のベース部と、該ベース部の長手方向両端から互いに離れる方向に延設された帯板状の一対のテープ巻き部と、前記ベース部の一方の面に設けられ、被取付部材の孔に圧入係止される係止部と、を備え、前記一対のテープ巻き部における前記係止部と反対側の面に、角部を有する複数の突起が設けられており、前記複数の突起には、互いに交わって前記角部を構成する第１の傾斜面及び該第１の傾斜面よりも傾斜角度が大きい第２の傾斜面を有する第１の突起及び第２の突起が含まれており、前記第１の突起は、前記第１の傾斜面が前記テープ巻き部の長手方向一端側に位置し、かつ、前記第２の傾斜面が前記テープ巻き部の長手方向他端側に位置しており、前記第２の突起は、前記第１の傾斜面が前記テープ巻き部の長手方向他端側に位置し、かつ、前記第２の傾斜面が前記テープ巻き部の長手方向一端側に位置していることを特徴とする。
本発明のクランプは、帯板状のベース部と、該ベース部の長手方向両端から互いに離れる方向に延設された帯板状の一対のテープ巻き部と、前記ベース部の一方の面に設けられ、被取付部材の孔に圧入係止される係止部と、を備え、前記一対のテープ巻き部における前記係止部と反対側の面に、角部を有する複数の突起が設けられており、前記一対のテープ巻き部における前記係止部側の面に、複数の突起が設けられていることを特徴とする。 The clamp of the present invention is provided on one surface of a strip-shaped base portion, a pair of strip-shaped tape winding portions extending in directions away from both ends in the longitudinal direction of the base portion, and the base portion. A plurality of protrusions having corners are provided on a surface of the pair of tape winding portions opposite to the locking portion, which is provided with a locking portion which is press-fitted and locked in a hole of the member to be attached. The plurality of protrusions have a first inclined surface that intersects with each other to form the corner portion and a second inclined surface having an inclination angle larger than that of the first inclined surface. The first inclined surface is located on one end side in the longitudinal direction of the tape winding portion, and the second inclined surface is the longitudinal length of the tape winding portion. The second inclined surface is located on the other end side in the direction, the first inclined surface is located on the other end side in the longitudinal direction of the tape winding portion, and the second inclined surface is the tape winding portion. It is characterized in that it is located on one end side in the longitudinal direction of the portion.
The clamp of the present invention is provided on one surface of a strip-shaped base portion, a pair of strip-shaped tape winding portions extending in directions away from both ends in the longitudinal direction of the base portion, and the base portion. A plurality of protrusions having corners are provided on the surface of the pair of tape winding portions opposite to the locking portion. It is characterized in that a plurality of protrusions are provided on the surface of the pair of tape winding portions on the locking portion side.

本発明によれば、前記一対のテープ巻き部における前記係止部と反対側の面に、角部を有する複数の突起が設けられているので、本クランプが取り付けられたワイヤハーネスに引張力が及んだ際、ワイヤハーネスの外表面に食い込んだ複数の突起が滑り止めとして機能し、ワイヤハーネスとクランプとの相対的移動を抑制することができる。即ち、本発明の前記突起は角部を有しているので、表面が弧状である従来例の当接用リブ（図７，８）と比較して、ワイヤハーネスに対する引っ掛かり作用が大きい。 According to the present invention, since a plurality of protrusions having corners are provided on the surface of the pair of tape winding portions opposite to the locking portion, a tensile force is applied to the wire harness to which the clamp is attached. When it reaches, the plurality of protrusions that bite into the outer surface of the wire harness function as anti-slip, and the relative movement between the wire harness and the clamp can be suppressed. That is, since the protrusion of the present invention has a corner portion, the hooking action on the wire harness is larger than that of the conventional contact rib (FIGS. 7 and 8) having an arc-shaped surface.

The seal portion 8 is a portion that closes the gap between the periphery of the base end portion of the locking portion 4 and the vehicle body panel 9.

ベース部２は、帯板状に形成されている。図１〜６において、矢印Ｘはベース部２の長手方向と平行であり、矢印Ｙはベース部２の厚み方向と平行であり、矢印Ｚはベース部２の幅方向と平行である。 The base portion 2 is formed in a strip shape. In FIGS. 1 to 6, the arrow X is parallel to the longitudinal direction of the base portion 2, the arrow Y is parallel to the thickness direction of the base portion 2, and the arrow Z is parallel to the width direction of the base portion 2.

一対のテープ巻き部３ａ，３ｂは、それぞれ、ベース部２の長手方向両端から互いに離れる方向に延設されており、帯板状に形成されている。一対のテープ巻き部３ａ，３ｂの長手方向は、矢印Ｘと平行である。一対のテープ巻き部３ａ，３ｂの厚み寸法は、ベース部２の厚み寸法と等しい。一対のテープ巻き部３ａ，３ｂの一方の面３１は、ベース部２の一方の面２１と面一である。また、一対のテープ巻き部３ａ，３ｂの他方の面３２は、ベース部２の他方の面２２と面一である。また、ベース部２及び一対のテープ巻き部３ａ，３ｂは、他方の面２２，３２がワイヤハーネス１０に沿わされる。一対のテープ巻き部３ａ，３ｂの一方の面３１は、テープ１１と重なる面である。 Each of the pair of tape winding portions 3a and 3b extends in a direction away from both ends in the longitudinal direction of the base portion 2 and is formed in a strip shape. The longitudinal direction of the pair of tape winding portions 3a and 3b is parallel to the arrow X. The thickness dimension of the pair of tape winding portions 3a and 3b is equal to the thickness dimension of the base portion 2. One surface 31 of the pair of tape winding portions 3a and 3b is flush with one surface 21 of the base portion 2. Further, the other surface 32 of the pair of tape winding portions 3a and 3b is flush with the other surface 22 of the base portion 2. Further, the other surfaces 22 and 32 of the base portion 2 and the pair of tape winding portions 3a and 3b are aligned with the wire harness 10. One surface 31 of the pair of tape winding portions 3a and 3b is a surface that overlaps with the tape 11.

また、一対のテープ巻き部３ａ，３ｂの長手方向のベース部２から離れた端部には、それぞれ、テープ１１のずれを防止するためのリブ７ａ，７ｂが設けられている。リブ７ａ，７ｂは、テープ巻き部３ａ，３ｂの各面３１に設けられ、テープ巻き部３ａ，３ｂの幅方向の全域にわたって設けられている。 Further, ribs 7a and 7b for preventing the tape 11 from being displaced are provided at the ends of the pair of tape winding portions 3a and 3b separated from the base portion 2 in the longitudinal direction, respectively. The ribs 7a and 7b are provided on each surface 31 of the tape winding portions 3a and 3b, and are provided over the entire width direction of the tape winding portions 3a and 3b.

係止部４は、ベース部２の一方の面２１に設けられており、当該一方の面２１の中央部から立設した支柱４１と、支柱４１の先端からベース部２側に延びた弾性変形自在な一対の係止片４２と、を有している。一対の係止片４２は、支柱４１の先端側からベース部２側に向かうにしたがって徐々に互いの間隔を広げるように、支柱４１の立設方向に対して斜め方向に延びている。各係止片４２の先端には、段状の係止肩部４３が形成されている。このような係止部４は、支柱４１の先端側から車体パネル９の孔９０に圧入され、一対の係止片４２の各係止肩部４３が孔９０の縁（車体パネル９の一方の面９１側の縁）に係合することにより、孔９０に係止される。 The locking portion 4 is provided on one surface 21 of the base portion 2, and has a strut 41 erected from the central portion of the one surface 21 and an elastic deformation extending from the tip of the strut 41 toward the base portion 2. It has a pair of free locking pieces 42 and. The pair of locking pieces 42 extend obliquely with respect to the erection direction of the columns 41 so as to gradually increase the distance between the locking pieces 42 from the tip end side of the columns 41 toward the base portion 2 side. A stepped locking shoulder 43 is formed at the tip of each locking piece 42. Such a locking portion 4 is press-fitted into the hole 90 of the vehicle body panel 9 from the tip end side of the support column 41, and each locking shoulder portion 43 of the pair of locking pieces 42 is the edge of the hole 90 (one of the vehicle body panels 9). By engaging with the edge on the surface 91 side), it is locked to the hole 90.

シール部８は、ベース部２の一方の面２１に、係止部４の基端部を囲むように環状に設けられている。シール部８は、車体パネル９の他方の面９２における孔９０の外周部分に密着して、係止部４の基端部周囲と車体パネル９との隙間を塞ぐ。 The seal portion 8 is provided on one surface 21 of the base portion 2 in an annular shape so as to surround the base end portion of the locking portion 4. The seal portion 8 is in close contact with the outer peripheral portion of the hole 90 on the other surface 92 of the vehicle body panel 9 to close the gap between the periphery of the base end portion of the locking portion 4 and the vehicle body panel 9.

一対のテープ巻き部３ａ，３ｂにおける係止部４と反対側の面、即ち他方の面３２には、複数の突起が設けられている。これら複数の突起は、テープ巻き部３ａ，３ｂの長手方向と幅方向の両方向に分散配置されている。本実施形態では、前記複数の突起が、後述する複数の第１の突起５ａ及び複数の第２の突起５ｂのみで構成されているが、前記「複数の突起」には、第１の突起５ａ及び第２の突起５ｂ以外の形状の突起が含まれていてもよい。 A plurality of protrusions are provided on the surface of the pair of tape winding portions 3a and 3b opposite to the locking portion 4, that is, the other surface 32. These plurality of protrusions are dispersedly arranged in both the longitudinal direction and the width direction of the tape winding portions 3a and 3b. In the present embodiment, the plurality of protrusions are composed of only a plurality of first protrusions 5a and a plurality of second protrusions 5b, which will be described later, but the "plurality of protrusions" includes the first protrusion 5a. And a protrusion having a shape other than the second protrusion 5b may be included.

第１の突起５ａ及び第２の突起５ｂは、図５に示すように、角部５３と、互いに交わって角部５３を構成する（即ち角度θ３を成す）第１の傾斜面５１及び第２の傾斜面５２を有し、断面形状が三角形に形成されている。第１の傾斜面５１は、面３２と交わって角度θ１を成す傾斜面である。第２の傾斜面５２は、面３２と交わって角度θ２を成す傾斜面である。第２の傾斜面５２は、第１の傾斜面５１よりも面３２に対する傾斜角度が大きい。即ち、角度θ２は角度θ１よりも大きい。第２の傾斜面５２の傾斜角度（即ち角度θ２）は９０度に近い方がよく、本実施形態では８０度程度である。 As shown in FIG. 5, the first protrusion 5a and the second protrusion 5b intersect with the corner portion 53 to form the corner portion 53 (that is, form an angle θ3), and the first inclined surface 51 and the second. It has an inclined surface 52 of the above, and the cross-sectional shape is formed into a triangle. The first inclined surface 51 is an inclined surface that intersects with the surface 32 and forms an angle θ1. The second inclined surface 52 is an inclined surface that intersects with the surface 32 and forms an angle θ2. The second inclined surface 52 has a larger inclination angle with respect to the surface 32 than the first inclined surface 51. That is, the angle θ2 is larger than the angle θ1. The inclination angle (that is, the angle θ2) of the second inclined surface 52 should be close to 90 degrees, which is about 80 degrees in the present embodiment.

第１の突起５ａは、第１の傾斜面５１がテープ巻き部３ａ，３ｂの長手方向一端側（本実施形態では、図１中左側であり、一方のリブ７ａ側）に位置し、かつ、第２の傾斜面５２がテープ巻き部３ａ，３ｂの長手方向他端側（本実施形態では、図１中右側であり、他方のリブ７ｂ側）に位置している。 In the first protrusion 5a, the first inclined surface 51 is located on one end side in the longitudinal direction of the tape winding portions 3a and 3b (in this embodiment, the left side in FIG. 1 and one rib 7a side). The second inclined surface 52 is located on the other end side of the tape winding portions 3a and 3b in the longitudinal direction (in the present embodiment, the right side in FIG. 1 and the other rib 7b side).

第２の突起５ｂは、第１の傾斜面５１がテープ巻き部３ａ，３ｂの長手方向他端側（本実施形態では、図１中右側であり、他方のリブ７ｂ側）に位置し、かつ、第２の傾斜面５２がテープ巻き部３ａ，３ｂの長手方向一端側（本実施形態では、図１中左側であり、一方のリブ７ａ側）に位置している。 In the second protrusion 5b, the first inclined surface 51 is located on the other end side of the tape winding portions 3a and 3b in the longitudinal direction (in the present embodiment, the right side in FIG. 1 and the other rib 7b side). The second inclined surface 52 is located on one end side in the longitudinal direction of the tape winding portions 3a and 3b (in this embodiment, the left side in FIG. 1 and one rib 7a side).

本実施形態では、図３に示すように、第１の突起５ａと第２の突起５ｂが、テープ巻き部３ａ，３ｂの長手方向に交互に配置されている。また、図４に示すように、第１の突起５ａと第２の突起５ｂが、テープ巻き部３ａ，３ｂの幅方向に交互に配置されている。 In the present embodiment, as shown in FIG. 3, the first protrusions 5a and the second protrusions 5b are alternately arranged in the longitudinal direction of the tape winding portions 3a and 3b. Further, as shown in FIG. 4, the first protrusions 5a and the second protrusions 5b are alternately arranged in the width direction of the tape winding portions 3a and 3b.

上記構成のテープ巻き部３ａ，３ｂとワイヤハーネス１０とがテープ１１の巻き付けによって固定されることにより、上記複数の突起、即ち複数の第１の突起５ａ及び複数の第２の突起５ｂが、ワイヤハーネス１０の外表面を窪ませて当該外表面に食い込む。このことにより、クランプ付きワイヤハーネス１５に引張力（配索時に引っ張られることによる引張力であり、引っ張り方向を図６に矢印Ｐで示す。）が及んだ際、複数の突起５ａ，５ｂが滑り止めとして機能し、ワイヤハーネス１０とクランプ１との相対的移動を抑制することができる。即ち、突起５ａ，５ｂは角部５３を有しているので、表面が弧状である従来例の当接用リブ（図７，８）と比較して、ワイヤハーネス１０に対する引っ掛かり作用が大きい。 By fixing the tape winding portions 3a and 3b and the wire harness 10 having the above configuration by winding the tape 11, the plurality of protrusions, that is, the plurality of first protrusions 5a and the plurality of second protrusions 5b become wires. The outer surface of the harness 10 is recessed and bites into the outer surface. As a result, when a tensile force (which is a tensile force due to being pulled during routing and the pulling direction is indicated by an arrow P in FIG. 6) is applied to the clamped wire harness 15, the plurality of protrusions 5a and 5b are formed. It functions as a non-slip and can suppress the relative movement of the wire harness 10 and the clamp 1. That is, since the protrusions 5a and 5b have the corners 53, the hooking action on the wire harness 10 is larger than that of the conventional contact ribs (FIGS. 7 and 8) having an arc-shaped surface.

また、複数の突起５ａ，５ｂはテープ巻き部３ａ，３ｂの長手方向と幅方向の両方向に分散配置されているので、ワイヤハーネス１０に対する引っ掛かり作用を広範囲に発揮することができる。 Further, since the plurality of protrusions 5a and 5b are dispersedly arranged in both the longitudinal direction and the width direction of the tape winding portions 3a and 3b, the hooking action on the wire harness 10 can be exerted in a wide range.

また、第１の突起５ａと第２の突起５ｂが矢印Ｘ方向に交互に配置されているので、クランプ付きワイヤハーネス１５に矢印Ｐの一方向側から引張力が及んだ際でも、矢印Ｐの他方向側から引張力が及んだ際でも、第１の突起５ａと第２の突起５ｂのどちらか一方は、急な傾斜面５２がワイヤハーネス引張方向に対向しているので、ワイヤハーネス１０とクランプ１との相対的移動を抑制することができる。 Further, since the first protrusions 5a and the second protrusions 5b are alternately arranged in the direction of the arrow X, the arrow P is applied even when a tensile force is applied to the clamped wire harness 15 from one direction of the arrow P. Even when a tensile force is applied from the other direction side, one of the first protrusion 5a and the second protrusion 5b has a steep inclined surface 52 facing the wire harness pulling direction, so that the wire harness The relative movement between the 10 and the clamp 1 can be suppressed.

さらに、図１，５，６に示すように、一対のテープ巻き部３ａ，３ｂにおける係止部４側の面、即ち一方の面３１には、複数の突起が設けられている。これら複数の突起は、上述した複数の突起５ａ，５ｂと同様に、テープ巻き部３ａ，３ｂの長手方向と幅方向の両方向に分散配置されている。本実施形態では、前記複数の突起が、後述する複数の第３の突起６ａ及び複数の第４の突起６ｂのみで構成されているが、前記「複数の突起」には、第３の突起６ａ及び第４の突起６ｂ以外の形状の突起が含まれていてもよい。 Further, as shown in FIGS. 1, 5 and 6, a plurality of protrusions are provided on the surface of the pair of tape winding portions 3a and 3b on the locking portion 4 side, that is, one surface 31. Similar to the plurality of protrusions 5a and 5b described above, the plurality of protrusions are dispersedly arranged in both the longitudinal direction and the width direction of the tape winding portions 3a and 3b. In the present embodiment, the plurality of protrusions are composed of only a plurality of third protrusions 6a and a plurality of fourth protrusions 6b, which will be described later, but the "plurality of protrusions" includes the third protrusion 6a.

第３の突起６ａ及び第４の突起６ｂは、図５に示すように、角部６３と、互いに交わって角部６３を構成する（即ち角度θ６を成す）第３の傾斜面６１及び第４の傾斜面６２を有し、断面形状が三角形に形成されている。第３の傾斜面６１は、面３１と交わって角度θ４を成す傾斜面である。第４の傾斜面６２は、面３１と交わって角度θ５を成す傾斜面である。第４の傾斜面６２は、第３の傾斜面６１よりも面３１に対する傾斜角度が大きい。即ち、角度θ５は角度θ４よりも大きい。第４の傾斜面６２の傾斜角度（即ち角度θ５）は９０度に近い方がよく、本実施形態では８０度程度である。 As shown in FIG. 5, the third protrusion 6a and the fourth protrusion 6b intersect with the corner portion 63 to form the corner portion 63 (that is, form an angle θ6), and the third inclined surface 61 and the fourth. It has an inclined surface 62 and has a triangular cross-sectional shape. The third inclined surface 61 is an inclined surface that intersects with the surface 31 and forms an angle θ4. The fourth inclined surface 62 is an inclined surface that intersects with the surface 31 and forms an angle θ5. The fourth inclined surface 62 has a larger inclination angle with respect to the surface 31 than the third inclined surface 61. That is, the angle θ5 is larger than the angle θ4. The inclination angle (that is, the angle θ5) of the fourth inclined surface 62 should be close to 90 degrees, which is about 80 degrees in the present embodiment.

第３の突起６ａは、第３の傾斜面６１がテープ巻き部３ａ，３ｂの長手方向一端側（本実施形態では、図１中左側であり、一方のリブ７ａ側）に位置し、かつ、第４の傾斜面６２がテープ巻き部３ａ，３ｂの長手方向他端側（本実施形態では、図１中右側であり、他方のリブ７ｂ側）に位置している。 In the third protrusion 6a, the third inclined surface 61 is located on one end side in the longitudinal direction of the tape winding portions 3a and 3b (in this embodiment, the left side in FIG. 1 and one rib 7a side). The fourth inclined surface 62 is located on the other end side of the tape winding portions 3a and 3b in the longitudinal direction (in this embodiment, the right side in FIG. 1 and the other rib 7b side).

第４の突起６ｂは、第３の傾斜面６１がテープ巻き部３ａ，３ｂの長手方向他端側（本実施形態では、図１中右側であり、他方のリブ７ｂ側）に位置し、かつ、第４の傾斜面６２がテープ巻き部３ａ，３ｂの長手方向一端側（本実施形態では、図１中左側であり、一方のリブ７ａ側）に位置している。 In the fourth protrusion 6b, the third inclined surface 61 is located on the other end side of the tape winding portions 3a and 3b in the longitudinal direction (in the present embodiment, the right side in FIG. 1 and the other rib 7b side). The fourth inclined surface 62 is located on one end side in the longitudinal direction of the tape winding portions 3a and 3b (in this embodiment, the left side in FIG. 1 and one rib 7a side).

本実施形態では、図１に示すように、第３の突起６ａと第４の突起６ｂが、テープ巻き部３ａ，３ｂの長手方向に交互に配置されている。また、図示は省略するが、第３の突起６ａと第４の突起６ｂが、テープ巻き部３ａ，３ｂの幅方向に交互に配置されている。 In the present embodiment, as shown in FIG. 1, the third protrusions 6a and the fourth protrusions 6b are alternately arranged in the longitudinal direction of the tape winding portions 3a and 3b. Although not shown, the third protrusions 6a and the fourth protrusions 6b are alternately arranged in the width direction of the tape winding portions 3a and 3b.

上記構成のテープ巻き部３ａ，３ｂとワイヤハーネス１０とがテープ１１の巻き付けによって固定されることにより、クランプ付きワイヤハーネス１５に引張力が及んだ際、複数の突起６ａ，６ｂが滑り止めとして機能し、テープ１１とクランプ１との相対的移動を抑制することができる。 By fixing the tape winding portions 3a and 3b and the wire harness 10 having the above configuration by winding the tape 11, when a tensile force is applied to the wire harness 15 with a clamp, the plurality of protrusions 6a and 6b serve as non-slip. It functions and can suppress the relative movement of the tape 11 and the clamp 1.
