Description

この発明は、ワイヤーハーネスの分岐部を覆いつつその経路を一定に維持する技術に関する。   The present invention relates to a technique for keeping the path constant while covering a branch portion of a wire harness.

従来より、特許文献１〜４に開示のように、車両等に敷設されるワイヤーハーネスを、屈曲性良好なコルゲートチューブにて覆う技術が知られている。   Conventionally, as disclosed in Patent Documents 1 to 4, a technique of covering a wire harness laid on a vehicle or the like with a corrugated tube having good flexibility is known.

実開平４−８６０２２号公報Japanese Utility Model Publication No. 4-86022 特開２０００−１８４５５１号公報JP 2000-184551 A 特開２００２−６４９１７号公報JP 2002-64917 A 特開２００６−２９６１６６号公報JP 2006-296166 A

しかしながら、コルゲートチューブ自体は、屈曲性に優れるもの故、それ自体はワイヤーハーネスの経路を一定に維持する機能を持たない。このため、ワイヤーハーネス或はコルゲートチューブに取付けられたクランプ部材を車両の一定位置に固定することで、ワイヤーハーネスの経路を一定に維持する必要がある。クランプ部材の固定箇所が多くなると、部品コスト増、取付けコスト増等を招く恐れがある。   However, since the corrugated tube itself is excellent in flexibility, the corrugated tube itself does not have a function of keeping the path of the wire harness constant. For this reason, it is necessary to maintain the path | route of a wire harness constant by fixing the clamp member attached to the wire harness or the corrugated tube to the fixed position of a vehicle. When the number of fixing portions of the clamp member is increased, there is a risk of increasing the component cost and the mounting cost.

ここで、ワイヤーハーネスの敷設箇所に合わせた形状に形成した樋状の樹脂成型品（プロテクタ）によれば、ワイヤーハーネスを保護しつつその経路を一定に維持することができる。   Here, according to the bowl-shaped resin molded product (protector) formed in a shape according to the laying position of the wire harness, the path can be maintained constant while protecting the wire harness.

しかしながら、ワイヤーハーネスを保護可能な樹脂成型品を、ワイヤーハーネスの敷設箇所に合わせて３次元形状等の複雑な形成するためには、その金型形状が複雑化してしまう。このため、製造コストが高くなる。   However, in order to form a resin molded product capable of protecting the wire harness in a complicated shape such as a three-dimensional shape in accordance with the laying position of the wire harness, the mold shape becomes complicated. For this reason, a manufacturing cost becomes high.

そこで、本願発明者らによって、コルゲートチューブに、長手方向に沿って一定形状を維持するように金型成型された経路維持部材を取付けて、コルゲートチューブ及び内部のワイヤーハーネスを一定形状に維持する構成が提案されている。経路維持部材をコルゲートチューブに取付ける構成としては、経路維持部材に一対の凹溝部を形成し、コルゲートチューブのうちスリットの両側の端縁部を前記一対の凹溝部に嵌め込む構成が提案されている。   Accordingly, the inventors of the present application attach a path maintaining member molded to maintain a constant shape along the longitudinal direction to the corrugated tube, and maintain the corrugated tube and the internal wire harness in a fixed shape. Has been proposed. As a configuration for attaching the path maintaining member to the corrugated tube, a configuration is proposed in which a pair of concave grooves are formed in the path maintaining member, and edge portions on both sides of the slit of the corrugated tube are fitted into the pair of concave grooves. .

ところで、ワイヤーハーネスでは、通常、複数の電線が分岐するように束ねられている。ワイヤーハーネスの分岐部を所定の分岐方向に沿って維持するためには、経路維持部材を多方向に分岐するように形成することになる。   By the way, in a wire harness, the some electric wire is normally bundled so that it may branch. In order to maintain the branch portion of the wire harness along a predetermined branch direction, the path maintaining member is formed to branch in multiple directions.

しかしながら、経路維持部材には一対の凹溝部が形成されているため、分岐部で形状が複雑となる。このため、経路維持部材を金型成型等することが困難となる。   However, since the pair of concave grooves are formed in the path maintaining member, the shape becomes complicated at the branch portion. For this reason, it becomes difficult to mold the path maintaining member.

そこで、本発明は、コルゲートチューブに経路維持部材を取付けることによって、ワイヤーハーネス本体部の分岐部の周辺部を覆いつつそれらの分岐方向を一定に維持する際に、経路維持部材の形成を容易にできるようにすることを目的とする。   Therefore, the present invention attaches a path maintaining member to the corrugated tube, thereby easily forming the path maintaining member when maintaining the branch direction constant while covering the peripheral part of the branch part of the wire harness main body part. The purpose is to be able to.

Can be covered. In addition, by attaching the path maintaining extension part to the corrugated tube so that the edge portions on both sides of the slit of each corrugated tube are accommodated in the pair of concave grooves, the wire harness branch extending by the path maintaining extension part The branch direction of the part can be kept constant.

以下、実施形態に係るワイヤーハーネス及び経路維持部材付コルゲートチューブについて説明する。図１はワイヤーハーネス１０のうちコルゲートチューブ２０の装着部分を示す概略平面図であり、図２はコルゲートチューブ２０に経路維持部材３０を取付けた一部分を示す概略斜視図であり、図３は経路維持部材３０を示す概略斜視図である。   Hereinafter, the corrugated tube with a wire harness and a path maintaining member according to the embodiment will be described. FIG. 1 is a schematic plan view showing a mounting portion of the corrugated tube 20 in the wire harness 10, FIG. 2 is a schematic perspective view showing a part of the corrugated tube 20 attached with a route maintaining member 30, and FIG. 3 is a schematic perspective view showing a member 30. FIG.

このワイヤーハーネス１０は、ワイヤーハーネス本体部１２の分岐部１４の周辺部に装着されるものであり、ワイヤーハーネス本体部１２と、コルゲートチューブ２０と、経路維持部材３０とを備える。   The wire harness 10 is attached to the peripheral portion of the branch portion 14 of the wire harness main body 12 and includes the wire harness main body 12, the corrugated tube 20, and the path maintaining member 30.

ワイヤーハーネス本体部１２は、複数の電線が配設対象となる車両への配線形態に応じて分岐しつつ結束された構成とされている。本実施形態では、複数の電線が３つに分岐するように結束された箇所、即ち、分岐部１４から３つのワイヤーハーネス分岐延出部１５が延出する箇所に適用した例で説明する。もっとも、複数の電線が４つ以上に分岐するように結束された箇所であってもよい。また、ワイヤーハーネス本体部１２に、他の光ケーブル等が結束されていてもよい。   The wire harness main body 12 has a configuration in which a plurality of electric wires are bundled while being branched according to a wiring form to a vehicle to be disposed. In the present embodiment, an example in which the present invention is applied to a portion where a plurality of electric wires are bundled so as to branch into three, that is, a portion where three wire harness branch extending portions 15 extend from the branch portion 14 will be described. But the location bound so that a some electric wire may branch into four or more may be sufficient. Further, another optical cable or the like may be bound to the wire harness main body 12.

上記ワイヤーハーネス本体部１２を、車両等に配設する際、ワイヤーハーネス本体部１２はその配設形態に沿って配索される。ワイヤーハーネス本体部１２が周辺部分に干渉すること等を抑制するため、分岐部１４の周辺においては、分岐部１４からの各ワイヤーハーネス分岐延出部１５の延出方向が一定に維持されることがある。また、ワイヤーハーネス本体部１２はその配線形態に沿った形状に維持されることがある。このような場合に、本経路維持部材付コルゲートチューブＣがワイヤーハーネス本体部１２のうち上記分岐部１４の周辺に装着され、各ワイヤーハーネス分岐延出部１５の延出方向を一定に維持する。また、本経路維持部材付コルゲートチューブＣは、各ワイヤーハーネス分岐延出部１５を一定の形状に維持することもできる。なお、ワイヤーハーネス本体部１２に対して本経路維持部材付コルゲートチューブＣが装着される部分は、ワイヤーハーネス本体部１２の分岐部１４周辺の少なくとも一部であればよい。   When arrange | positioning the said wire harness main-body part 12 in a vehicle etc., the wire harness main-body part 12 is routed along the arrangement | positioning form. In order to prevent the wire harness body 12 from interfering with the peripheral portion, etc., the extension direction of each wire harness branch extension 15 from the branch 14 is kept constant in the vicinity of the branch 14. There is. Moreover, the wire harness main-body part 12 may be maintained in the shape along the wiring form. In such a case, the corrugated tube C with a path maintaining member is attached to the periphery of the branching portion 14 in the wire harness main body 12 and maintains the extending direction of each wire harness branch extending portion 15 constant. Moreover, this corrugated tube C with a path | route maintenance member can also maintain each wire harness branch extension part 15 in a fixed shape. In addition, the part by which this corrugated tube C with this route maintenance member is mounted | worn with respect to the wire harness main-body part 12 should just be at least one part of the branch part 14 periphery of the wire harness main-body part 12. FIG.

コルゲートチューブ２０は、長手方向に沿って環状凸部２１と環状凹部２２とが交互に形成された筒状部材であり（図２参照）、樹脂等で形成されている。かかるコルゲートチューブ２０は、環状凸部２１と環状凹部２２との間の段部等で容易に弾性変形するため、それ自体では全体として曲げ変形容易な性質を有している。通常、コルゲートチューブ２０としては、装着対象となるワイヤーハーネス分岐延出部１５の部分の外径よりも大きい（通常は多少大きい程度）内径を有するものが用いられ、その内部にワイヤーハーネス分岐延出部１５を配設できるようになっている。   The corrugated tube 20 is a cylindrical member in which annular convex portions 21 and annular concave portions 22 are alternately formed along the longitudinal direction (see FIG. 2), and is formed of a resin or the like. Since the corrugated tube 20 is easily elastically deformed at a step portion between the annular convex portion 21 and the annular concave portion 22, the corrugated tube 20 itself has a property of being easily bent and deformed as a whole. Normally, as the corrugated tube 20, a tube having an inner diameter larger than the outer diameter of the portion of the wire harness branch extending portion 15 to be mounted (usually somewhat larger) is used, and the wire harness branch extending inside the corrugated tube 20 is used. The portion 15 can be disposed.

また、コルゲートチューブ２０の一側部にその長手方向に沿ってスリット２４が形成されている。そして、当該スリット２４で割開くようにして、ワイヤーハーネス分岐延出部１５をコルゲートチューブ２０内に容易に配設できるようになっている。   Further, a slit 24 is formed in one side portion of the corrugated tube 20 along the longitudinal direction thereof. The wire harness branch extending portion 15 can be easily disposed in the corrugated tube 20 so as to be opened by the slit 24.

ここでは、上記３つのワイヤーハーネス分岐延出部１５に対応してコルゲートチューブ２０が用いられる。各コルゲートチューブ２０としては、それぞれ収容態様となるワイヤーハーネス分岐延出部１５の径に応じたものを用いるとよい。   Here, the corrugated tube 20 is used corresponding to the three wire harness branch extending portions 15. As each corrugated tube 20, it is good to use the thing according to the diameter of the wire harness branch extension part 15 used as an accommodation aspect, respectively.

経路維持部材３０は、ブロック状部分３２と、複数の経路維持延出部４０とを備えている。   The path maintaining member 30 includes a block-shaped portion 32 and a plurality of path maintaining extending portions 40.

ブロック状部分３２は、凹みが無いブロック形状、例えば、球状、多面体形状（辺、角を丸め処理したものを含む）に形成されている。ここでは、ブロック状部分３２は、球状に形成されている。   The block-shaped portion 32 is formed in a block shape having no dent, for example, a spherical shape or a polyhedron shape (including rounded sides and corners). Here, the block-shaped part 32 is formed in a spherical shape.

複数の経路維持延出部４０との関係でいうと、ブロック状部分３２は、複数の経路維持延出部４０の内側への延出エリアの３次元的な重複エリア（図１の平面図で斜線を付したエリアＡ参照）を包含する形状に形成されていることが好ましい。つまり、各経路維持延出部４０をブロック状部分３２側に向けて延出させた空間エリアを想定すると、ブロック状部分３２は、各空間エリアの全てが重複するエリアＡを包含するような大きさに設定されていることが好ましい。本実施形態でも、ブロック状部分３２は、前記エリアＡよりも大きな直径の球状に形成されている。   In terms of the relationship with the plurality of route maintaining / extending portions 40, the block-shaped portion 32 has a three-dimensional overlapping area (in the plan view of FIG. 1) of the extending area to the inside of the plurality of route maintaining / extending portions 40. It is preferably formed in a shape including a hatched area A). That is, assuming a spatial area in which each path maintaining extension 40 is extended toward the block-shaped portion 32 side, the block-shaped portion 32 is large enough to include an area A where all the spatial areas overlap. It is preferable that it is set. Also in this embodiment, the block-shaped portion 32 is formed in a spherical shape having a diameter larger than that of the area A.

複数の経路維持延出部４０は、上記ブロック状部分３２から延出するように形成されている。ここでは、平面視において、２つの経路維持延出部４０は、ブロック状部分３２の両側部から外方に向けて延出している（図１、図３参照）。また、平面視において、１つの経路維持延出部４０は、ブロック状部分３２から前記２つの経路維持延出部４０に対して直交する方向に延出している（図１、図３参照）。各経路維持延出部４０の上記延出方向は、一例であり、それぞれ異なる方向に延出していればよい。また、各経路維持延出部４０の中心軸周りの姿勢も相互に別々の姿勢であってもよい。   The plurality of path maintaining extension portions 40 are formed so as to extend from the block-shaped portion 32. Here, in a plan view, the two path maintaining extension portions 40 extend outward from both side portions of the block-like portion 32 (see FIGS. 1 and 3). Further, in plan view, one path maintaining extension 40 extends from the block-shaped portion 32 in a direction orthogonal to the two path maintaining extensions 40 (see FIGS. 1 and 3). The extension direction of each path maintenance extension part 40 is an example, and it is only necessary to extend in different directions. Also, the postures around the central axis of each path maintaining extension 40 may be different from each other.

上記したように、ブロック状部分３２は、エリアＡを含む大きさに形成されているため、複数の経路維持延出部４０は、ブロック状部分３２において直接交わらない。従って、各経路維持延出部４０の凹凸部分が複雑に入交じる箇所を抑制することができ、各経路維持延出部４０の交差部分の形状を単純化することができる。   As described above, since the block-shaped portion 32 is formed in a size including the area A, the plurality of path maintaining extension portions 40 do not intersect directly in the block-shaped portion 32. Therefore, it is possible to suppress the places where the uneven portions of each path maintaining extension 40 are intricately mixed, and the shape of the intersection of each path maintaining extension 40 can be simplified.

各経路維持延出部４０は、それぞれ長手方向に沿って一定の形状を維持可能な長尺部分に形成されている。ここでは、各経路維持延出部４０は、ブロック状部分３２と共に、Ｐ．Ｐ．（ポリプロピレン）等の樹脂によって一体に金型成型されている。従って、金型成型時点で、経路維持延出部４０は、直線状或は少なくとも一部が曲げられた形状に形成され、また、ワイヤーハーネス分岐延出部１５を一定の経路に沿って維持可能な剛性を有している。ここでは、図１及び図３では、直線状に形成された経路維持延出部４０を示しているが、経路維持延出部４０の少なくとも１つが少なくとも一部で曲げた形状に金型成型されていてもよい。   Each path maintenance extension part 40 is formed in the elongate part which can maintain a fixed shape along a longitudinal direction, respectively. Here, each of the route maintaining extension portions 40 is connected to the P.A. P. It is integrally molded with a resin such as (polypropylene). Therefore, at the time of mold forming, the path maintaining extension 40 is formed in a straight line shape or a shape in which at least a part thereof is bent, and the wire harness branch extension 15 can be maintained along a certain path. Has high rigidity. Here, in FIG. 1 and FIG. 3, the path maintaining extension 40 formed in a straight line is shown, but at least one of the path maintaining extension 40 is molded into a shape bent at least partially. It may be.

また、各経路維持延出部４０には、コルゲートチューブ２０のうちスリット２４の両側の端縁部を収容可能な一対の凹溝部４４ｇが形成された部分を有している。換言すれば、経路維持延出部４０は、長尺状の連結部４１の一方側（外周側）縁部に外周側突起部４２が設けられると共に、連結部４１の他方側（内周側）縁部に内周側突起部４３が設けられた構成され、その長手方向に対して直交する面における断面形状が略Ｈ字状を呈している。凹溝部４４ｇの幅寸法は、コルゲートチューブ２０の厚み寸法（より具体的には、コルゲートチューブ２０の径方向において環状凸部２１の最外周部分と環状凹部２２の最内周部分との差）と略同じかそれよりも大きい（僅かに大きい）程度の寸法に設定されている。凹溝部４４ｇの深さ寸法は、コルゲートチューブ２０の端縁部をその径方向にある程度位置決めした状態で収容できる程度であればよく、特に限定はない。   In addition, each path maintaining extension 40 has a portion in which a pair of concave grooves 44g capable of accommodating the edge portions on both sides of the slit 24 in the corrugated tube 20 are formed. In other words, the path maintaining extension part 40 is provided with the outer peripheral projection 42 on the one side (outer peripheral side) edge of the long connecting part 41 and the other side (inner peripheral side) of the connecting part 41. The inner peripheral projection 43 is provided at the edge, and the cross-sectional shape of the surface orthogonal to the longitudinal direction is substantially H-shaped. The width dimension of the recessed groove 44g is the thickness dimension of the corrugated tube 20 (more specifically, the difference between the outermost peripheral portion of the annular convex portion 21 and the innermost peripheral portion of the annular concave portion 22 in the radial direction of the corrugated tube 20). The dimensions are set to be approximately the same or larger (slightly larger). The depth dimension of the concave groove 44g is not particularly limited as long as it can be accommodated in a state where the end edge of the corrugated tube 20 is positioned to some extent in the radial direction.

上記経路維持延出部４０のうち上記一対の凹溝部４４ｇが形成された部分は、経路維持延出部４０の長手方向全体であってもよいし、その長手方向に沿った一部であってもよい。本実施形態では、一対の凹溝部４４ｇが経路維持延出部４０の長手方向全体に亘って形成された例で説明する。   The part of the path maintaining extension 40 where the pair of concave grooves 44g are formed may be the entire longitudinal direction of the path maintaining extension 40 or a part along the longitudinal direction. Also good. In the present embodiment, an example in which a pair of concave groove portions 44g are formed over the entire longitudinal direction of the path maintaining extension portion 40 will be described.

上記経路維持部材３０をワイヤーハーネス本体部１２の分岐部１４の周辺に取付ける作業手順について説明する。   An operation procedure for attaching the route maintaining member 30 to the periphery of the branch portion 14 of the wire harness main body 12 will be described.

まず、ワイヤーハーネス本体部１２の分岐部１４周辺において、コルゲートチューブ２０を前記スリット２４で開くことで、コルゲートチューブ２０内にワイヤーハーネス本体部１２のワイヤーハーネス分岐延出部１５を挿通状に収容する。同様にして、他のワイヤーハーネス分岐延出部１５にもコルゲートチューブ２０を装着する。   First, the corrugated tube 20 is opened by the slit 24 around the branching portion 14 of the wire harness main body 12 so that the wire harness branch extending portion 15 of the wire harness main body 12 is accommodated in the corrugated tube 20 in an insertion shape. . Similarly, the corrugated tube 20 is also attached to the other wire harness branch extension 15.

そして、各経路維持延出部４０をワイヤーハーネス分岐延出部１５に沿って配設するようにして、経路維持延出部４０をワイヤーハーネス本体部１２の分岐部１４周辺に配設する。そして、各ワイヤーハーネス分岐延出部１５において、コルゲートチューブ２０をスリット２４で開いて、コルゲートチューブ２０のうちスリット２４の両側の端縁部を一対の凹溝部４４ｇ内に嵌め込む。この状態では、連結部４１がスリット２４内に配設され、外周側突起部４２がスリット２４の外側でコルゲートチューブ２０の外周面に沿って配設され、内周側突起部４３がスリット２４の内側でコルゲートチューブ２０内周面に沿って配設される。これにより、各コルゲートチューブ２０及び内部のワイヤーハーネス分岐延出部１５は、経路維持延出部４０の延出方向に沿って一定形状に維持された状態で、当該経路維持延出部４０と一体化されることとなる。   The path maintaining extension 40 is disposed around the branching portion 14 of the wire harness main body 12 so that each path maintaining extending section 40 is disposed along the wire harness branching extending section 15. And in each wire harness branch extension part 15, the corrugated tube 20 is opened with the slit 24, and the edge part of the both sides of the slit 24 among the corrugated tubes 20 is engage | inserted in a pair of recessed groove part 44g. In this state, the connecting portion 41 is disposed in the slit 24, the outer peripheral projection 42 is disposed outside the slit 24 along the outer peripheral surface of the corrugated tube 20, and the inner peripheral projection 43 is the slit 24. It is arranged along the inner peripheral surface of the corrugated tube 20 on the inner side. Thereby, each corrugated tube 20 and the internal wire harness branch extension part 15 are united with the said path | route maintenance extension part 40 in the state maintained by the fixed shape along the extension direction of the path | route maintenance extension part 40. Will be converted.

この後、必要に応じて、タイバンド、粘着テープ等がコルゲートチューブ２０の外周に巻付けられ、コルゲートチューブ２０の閉状態が維持されると共に、コルゲートチューブ２０と経路維持延出部４０との一体化状態が維持され、経路維持部材３０がワイヤーハーネス本体部１２に取付けられる。   Thereafter, if necessary, a tie band, an adhesive tape or the like is wound around the outer periphery of the corrugated tube 20 so that the closed state of the corrugated tube 20 is maintained, and the corrugated tube 20 and the path maintaining extension 40 are integrated. The route maintaining member 30 is attached to the wire harness main body 12.

以上のように構成された経路維持部材付コルゲートチューブＣ及びワイヤーハーネス１０によると、コルゲートチューブ２０をワイヤーハーネス分岐延出部１５に外装することによって、ワイヤーハーネス本体部１２の分岐部１４の周辺部であるワイヤーハーネス分岐延出部１５を覆って保護することができる。また、コルゲートチューブ２０のスリット２４の両側の端縁部を一対の凹溝部４４ｇに収容するようにして、経路維持延出部４０をコルゲートチューブ２０に取付けることによって、当該経路維持延出部４０によりワイヤーハーネス分岐延出部１５の分岐方向を一定に維持できる。また、経路維持延出部４０の形状によって、ワイヤーハーネス分岐延出部１５をその長手方向に沿って一定形状（ここでは直線状に一定）に維持することができる。   According to the corrugated tube C with a path maintaining member and the wire harness 10 configured as described above, by surrounding the corrugated tube 20 on the wire harness branch extending portion 15, the peripheral portion of the branch portion 14 of the wire harness main body portion 12. It is possible to cover and protect the wire harness branch extending portion 15. Further, by attaching the path maintaining extension 40 to the corrugated tube 20 so that the edge portions on both sides of the slit 24 of the corrugated tube 20 are accommodated in the pair of concave grooves 44g, the path maintaining extending section 40 The branch direction of the wire harness branch extension 15 can be maintained constant. Moreover, the wire harness branch extension part 15 can be maintained in a fixed shape (here, constant in a straight line shape) along the longitudinal direction by the shape of the path maintaining extension part 40.

また、複数のワイヤーハーネス分岐延出部１５は、ブロック状部分３２から延出しているため、各ワイヤーハーネス分岐延出部１５の交差部分形状を簡素化することができる。特に、ブロック状部分３２を、複数の経路維持延出部４０の内側への延長エリアの３次元的な重複エリアを包含する形状に形成することで、当該ブロック状部分３２の形状をより確実に簡素化できる。   Moreover, since the several wire harness branch extension part 15 is extended from the block-shaped part 32, the cross | intersection part shape of each wire harness branch extension part 15 can be simplified. In particular, by forming the block-shaped portion 32 into a shape that includes a three-dimensional overlapping area of the extension area to the inside of the plurality of path maintenance extending portions 40, the shape of the block-shaped portion 32 can be more reliably formed. It can be simplified.

これにより、経路維持部材３０を樹脂の金型成型する際に、アンダーカット箇所等を抑制することができ、経路維持部材３０を容易に形成することができる。   Thereby, when the path | route maintenance member 30 is resin-molded, an undercut location etc. can be suppressed and the path | route maintenance member 30 can be formed easily.

また、複数のワイヤーハーネス分岐延出部１５の交差部分で、複数の経路維持延出部４０のコーナー部分、溝部分等が複雑に絡み合う形状部分を抑制することができ、経路維持部材をより容易に形成できる。これにより、尖って弱くなる箇所を抑制することができ、強度的にも優れたものとすることができる。   Further, at the intersections of the plurality of wire harness branch extending portions 15, it is possible to suppress a shape portion in which corner portions, groove portions, and the like of the plurality of route maintaining extension portions 40 are intertwined in a complicated manner, thereby making the route maintaining member easier. Can be formed. Thereby, the point which becomes sharp and weak can be suppressed, and it can be excellent in strength.

上記の結果、経路維持部材３０の設計工数削減等も容易となる。   As a result, the design man-hours and the like of the path maintaining member 30 can be easily reduced.

なお、上記したように、ブロック状部分３２は、球状の他の形状であってもよい。図４に示すように、ブロック状部分３２に対応するブロック状部分３２Ｂが直方体（ここでは立方体）形状に形成されていてもよい。   As described above, the block-shaped portion 32 may have another spherical shape. As shown in FIG. 4, the block-shaped part 32B corresponding to the block-shaped part 32 may be formed in a rectangular parallelepiped (here, a cube) shape.

この場合でも、上記と同様の効果を得ることができる。   Even in this case, the same effect as described above can be obtained.

なお、この場合、形状をより簡易化するため、各経路維持延出部４０は、ブロック状部分３２のいずれかの面から延出していることが好ましい。   In this case, in order to further simplify the shape, it is preferable that each path maintaining extension 40 extends from any surface of the block-shaped portion 32.

以上のようにこの発明は詳細に説明されたが、上記した説明は、すべての局面において、例示であって、この発明がそれに限定されるものではない。例示されていない無数の変形例が、この発明の範囲から外れることなく想定され得るものと解される。   As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
