　［本開示の実施形態の説明］
　最初に本開示の実施形態を列挙して説明する。
　［１］本開示の外装部材は、電線部材の外周を包囲する外装部材であって、筒状の可動部材と、前記可動部材を回転可能に保持する筒状の保持部材と、を備え、前記可動部材は、第１筒状部と、前記第１筒状部の軸方向の一端部に設けられるとともに前記第１筒状部と一体に形成された可動部と、前記可動部の外周面から外方に突出する支持軸とを有し、前記保持部材は、前記可動部が収容される収容空間と、前記支持軸が挿入される軸受孔とが設けられた保持部を有しており、前記第１筒状部は、前記保持部材の外部に設けられており、前記可動部は、前記支持軸を回転軸として前記保持部に対して回転可能に前記収容空間に収容されている。 [Description of embodiments of the present disclosure]
First, embodiments of the present disclosure will be listed and described.
[1] The exterior member of the present disclosure is an exterior member that surrounds the outer periphery of an electric wire member, and includes a cylindrical movable member and a cylindrical holding member that rotatably holds the movable member. The movable member includes a first cylindrical part, a movable part provided at one end of the first cylindrical part in the axial direction and integrally formed with the first cylindrical part, and a movable part from the outer peripheral surface of the movable part. and a support shaft protruding outward, the holding member having a holding part provided with a housing space in which the movable part is accommodated, and a bearing hole into which the support shaft is inserted, The first cylindrical part is provided outside the holding member, and the movable part is accommodated in the accommodation space so as to be rotatable with respect to the holding part about the support shaft as a rotation axis.
　この構成によれば、可動部材の可動部が保持部の収容空間に収容されるとともに、可動部材の支持軸が保持部の軸受孔に挿入される。このとき、可動部は、支持軸を回転軸として保持部に対して回転可能に収容空間内に収容される。これにより、可動部を、支持軸を回転軸として保持部に対して自由に回転させることができる。このような可動部に第１筒状部が一体に形成されている。このため、保持部材の外部に設けられた第１筒状部を、支持軸を回転軸として保持部に対して自由に回転させることができる。これにより、保持部材の外部に引き出される第１筒状部の引き出し方向を容易に可変することができる。したがって、ワイヤハーネスの経路が急峻に曲げられる場合であっても、その曲げ部分の経路に合わせて第１筒状部の引き出し方向を容易に調整することができる。この結果、ワイヤハーネスの経路に応じて外装部材を容易に変形させることができるため、外装部材を有するワイヤハーネスの配索性を向上できる。 According to this configuration, the movable part of the movable member is accommodated in the housing space of the holding part, and the support shaft of the movable member is inserted into the bearing hole of the holding part. At this time, the movable part is housed in the housing space so as to be rotatable with respect to the holding part about the support shaft as the rotation axis. Thereby, the movable part can be freely rotated with respect to the holding part using the support shaft as the rotation axis. A first cylindrical portion is integrally formed with such a movable portion. Therefore, the first cylindrical portion provided outside the holding member can be freely rotated with respect to the holding member using the support shaft as the rotation axis. Thereby, the direction in which the first cylindrical portion is pulled out to the outside of the holding member can be easily varied. Therefore, even if the path of the wire harness is sharply bent, the direction in which the first cylindrical portion is pulled out can be easily adjusted in accordance with the path of the bent portion. As a result, the sheathing member can be easily deformed according to the route of the wire harness, so that the routing performance of the wire harness having the sheathing member can be improved.
　さらに、保持部材の外部に引き出される部分には第１筒状部が設けられている。このため、外装部材の内部に電線部材が収容された場合に、保持部材の外部に引き出される電線部材の外周が第１筒状部により包囲される。これにより、保持部材の外部に引き出される電線部材の経路を第１筒状部により規制することができる。この結果、外装部材を有するワイヤハーネスの配索性を向上できる。 Furthermore, a first cylindrical portion is provided in the portion of the holding member that is pulled out. Therefore, when the electric wire member is housed inside the exterior member, the outer periphery of the electric wire member drawn out to the outside of the holding member is surrounded by the first cylindrical portion. Thereby, the path of the electric wire member drawn out to the outside of the holding member can be regulated by the first cylindrical portion. As a result, the ease of wiring the wire harness having the exterior member can be improved.
　ここで、本明細書における「筒状」は、周方向全周にわたって連続して周壁が形成されたものだけではなく、複数の部品を組み合わせて筒状をなすものも含まれる。本明細書における「筒状」は、外縁形状が球形のもの、外縁形状が円形のもの、外縁形状が多角形のものを含み、外縁形状が直線又は曲線で結ばれる任意の閉じた形状からなるものを言う。 Here, the term "cylindrical" in this specification includes not only one in which a peripheral wall is formed continuously over the entire circumferential direction, but also one in which a plurality of parts are combined to form a cylindrical shape. In this specification, "cylindrical" includes those with a spherical outer edge shape, circular outer edge shape, and polygonal outer edge shape, and is composed of any closed shape whose outer edge shape is connected by a straight line or a curved line. say something
　［２］上記［１］において、前記保持部は、前記保持部の軸方向の端面から前記軸受孔まで延びるガイド孔を有し、前記ガイド孔は、前記軸受孔側から前記保持部の軸方向の端面に向かうに連れて開口幅が大きくなるように形成されていることが好ましい。 [2] In the above [1], the holding part has a guide hole extending from the axial end surface of the holding part to the bearing hole, and the guide hole extends from the bearing hole side to the axial direction of the holding part. It is preferable that the opening width increases toward the end face of the opening.
　この構成によれば、保持部の軸方向の端面を切り欠くようにガイド孔が形成される。このガイド孔を通じて軸受孔に支持軸を挿入することができる。このとき、ガイド孔は、軸受孔側から保持部の軸方向の端面に向かうに連れて開口幅が大きくなるように傾斜して形成されている。このため、支持軸を軸受孔に挿入する際には、支持軸がガイド孔の斜面に沿って、保持部の軸方向の端面から軸受孔に向かって誘導される。これにより、支持軸を軸受孔に容易に挿入することができる。 According to this configuration, the guide hole is formed by cutting out the end surface of the holding portion in the axial direction. The support shaft can be inserted into the bearing hole through this guide hole. At this time, the guide hole is formed to be inclined so that the opening width increases from the bearing hole side toward the axial end surface of the holding portion. Therefore, when inserting the support shaft into the bearing hole, the support shaft is guided toward the bearing hole from the axial end surface of the holding portion along the slope of the guide hole. Thereby, the support shaft can be easily inserted into the bearing hole.
　［３］上記［２］において、前記ガイド孔の内面と前記軸受孔の内面との角部は、前記ガイド孔側の部分がＲ形状に形成されていることが好ましい。
　この構成によれば、ガイド孔の内面と軸受孔の内面との角部、つまりガイド孔と軸受孔とが連通する部分において、支持軸を軸受孔に挿入する際の入口となるガイド孔側の部分がＲ形状に形成される。これにより、ガイド孔の内面に形成されたＲ形状に沿って支持軸を軸受孔に向かってスムーズに誘導することができる。 [3] In the above [2], it is preferable that the corner portion between the inner surface of the guide hole and the inner surface of the bearing hole is formed into a rounded shape on the guide hole side.
According to this configuration, at the corner between the inner surface of the guide hole and the inner surface of the bearing hole, that is, at the portion where the guide hole and the bearing hole communicate, the guide hole side, which is the entrance when inserting the support shaft into the bearing hole, The portion is formed into an R shape. Thereby, the support shaft can be smoothly guided toward the bearing hole along the R shape formed on the inner surface of the guide hole.
　［４］上記［１］から［３］のいずれか１つにおいて、前記保持部は、前記可動部材の可動域を拡大する拡大空間を有し、前記拡大空間は、前記収容空間に連通するとともに、前記第１筒状部が挿入可能に形成されていることが好ましい。 [4] In any one of [1] to [3] above, the holding portion has an enlarged space that expands the range of motion of the movable member, and the enlarged space communicates with the accommodation space and Preferably, the first cylindrical portion is formed to be insertable.
　この構成によれば、保持部に、支持軸を回転軸として可動部を回転可能に収容する収容空間と、その収容空間に連通するとともに第１筒状部が挿入可能である拡大空間が設けられる。この拡大空間を設けたことにより、可動部の回転と連動して第１筒状部が可動する際に、拡大空間に挿入されるように第１筒状部を可動させることができる。このため、第１筒状部が拡大空間に挿入される分だけ、拡大空間が設けられている方向に対する第１筒状部の可動域を拡大することができる。これにより、可動部材の可動域を拡大することができる。 According to this configuration, the holding part is provided with an accommodation space that rotatably accommodates the movable part about the support shaft as a rotation axis, and an enlarged space that communicates with the accommodation space and into which the first cylindrical part can be inserted. . By providing this expanded space, when the first cylindrical portion moves in conjunction with the rotation of the movable portion, the first cylindrical portion can be moved so as to be inserted into the expanded space. Therefore, the movable range of the first cylindrical portion in the direction in which the expanded space is provided can be expanded by the amount that the first cylindrical portion is inserted into the expanded space. Thereby, the range of motion of the movable member can be expanded.
　［５］上記［４］において、前記拡大空間は、前記保持部の軸方向の端部に設けられた切り欠きであり、前記拡大空間は、前記保持部の周方向において、前記軸受孔と異なる位置に設けられていることが好ましい。 [5] In [4] above, the enlarged space is a notch provided at an axial end of the holding part, and the enlarged space is different from the bearing hole in the circumferential direction of the holding part. It is preferable that it be provided at a certain position.
　この構成によれば、保持部の軸方向の端部を切り欠くように拡大空間が形成される。このため、保持部の軸方向の端部により第１筒状部の可動域が制限されることを好適に抑制できる。これにより、第１筒状部の可動域を好適に拡大することができ、可動部材の可動域を好適に拡大することができる。 According to this configuration, the enlarged space is formed by cutting out the axial end of the holding part. Therefore, it is possible to suitably prevent the range of motion of the first cylindrical portion from being limited by the axial end portion of the holding portion. Thereby, the range of motion of the first cylindrical portion can be suitably expanded, and the range of motion of the movable member can be suitably expanded.
　［６］上記［４］又は［５］において、前記拡大空間は、前記保持部の軸方向に沿った長さ方向と、前記長さ方向と直交する幅方向と、前記長さ方向及び前記幅方向の双方と直交する貫通方向とに延在しており、前記拡大空間の前記幅方向に沿う最大寸法は、前記第１筒状部の前記幅方向に沿う最大寸法よりも大きく形成されるとともに、前記可動部の外形寸法よりも小さく形成されていることが好ましい。 [6] In [4] or [5] above, the expansion space includes a length direction along the axial direction of the holding portion, a width direction perpendicular to the length direction, and the length direction and the width. and a penetration direction perpendicular to both directions, and the maximum dimension of the expanded space along the width direction is larger than the maximum dimension of the first cylindrical portion along the width direction. , it is preferable that the movable part is formed smaller than the outer dimensions of the movable part.
　この構成によれば、拡大空間の幅方向に沿う最大寸法が第１筒状部の幅方向に沿う最大寸法よりも大きく形成されるため、第１筒状部を拡大空間に好適に挿入することができる。これにより、第１筒状部が拡大空間に挿入される分だけ、第１筒状部の可動域を好適に拡大することができるとともに、可動部材の可動域を好適に拡大することができる。また、拡大空間の幅方向に沿う最大寸法が可動部の外形寸法よりも小さく形成されるため、可動部が拡大空間を通じて保持部の外部に抜けることを好適に抑制できる。 According to this configuration, the maximum dimension along the width direction of the enlarged space is formed larger than the maximum dimension along the width direction of the first cylindrical part, so that the first cylindrical part can be suitably inserted into the enlarged space. Can be done. Thereby, the range of motion of the first cylindrical part can be suitably expanded by the amount that the first cylindrical part is inserted into the enlarged space, and the range of motion of the movable member can also be suitably expanded. Moreover, since the maximum dimension along the width direction of the enlarged space is formed smaller than the external dimension of the movable part, it is possible to suitably suppress the movable part from slipping out of the holding part through the enlarged space.
　［７］上記［１］から［６］のいずれか１つにおいて、前記可動部は、前記第１筒状部よりも外径の大きい球状に形成されており、前記可動部の径方向の厚みは、前記第１筒状部の径方向の厚みよりも厚く形成されていることが好ましい。 [7] In any one of [1] to [6] above, the movable part is formed in a spherical shape having a larger outer diameter than the first cylindrical part, and the radial thickness of the movable part is is preferably formed to be thicker than the radial thickness of the first cylindrical portion.
　この構成によれば、保持部の収容空間に収容される可動部の径方向の厚みが、第１筒状部の径方向の厚みよりも厚く形成される。これにより、可動部の厚みと第１筒状部の厚みとが等しい場合に比べて、可動部の剛性を向上させることができ、可動部が変形することを抑制できる。ここで、本明細書における「球状」は、真球に限定されるものではなく、楕円球等の若干変形した球形や表面に若干の凹凸がある球形も含まれる。 According to this configuration, the radial thickness of the movable part accommodated in the accommodation space of the holding part is formed to be thicker than the radial thickness of the first cylindrical part. Thereby, compared to the case where the thickness of the movable part and the thickness of the first cylindrical part are equal, the rigidity of the movable part can be improved and deformation of the movable part can be suppressed. Here, "spherical" in this specification is not limited to a true sphere, but also includes a slightly deformed spherical shape such as an elliptical sphere, and a spherical shape with some irregularities on the surface.
　［８］上記［７］において、前記可動部は、前記第１筒状部に接続される可動側第１端部と、前記可動部の軸方向において前記可動側第１端部の反対側に設けられた可動側第２端部とを有し、前記可動部の内周面は、前記可動側第１端部側から前記可動側第２端部に向かうに連れて、前記可動部の径方向外側に傾斜する傾斜面を有していることが好ましい。 [8] In [7] above, the movable part has a movable first end connected to the first cylindrical part, and a movable first end opposite to the movable first end in the axial direction of the movable part. a movable-side second end provided therein, and the inner circumferential surface of the movable part increases in diameter from the movable-side first end toward the movable-side second end. It is preferable to have an inclined surface inclined outward in the direction.
　この構成によれば、可動部の内周面に傾斜面が設けられることにより、可動側第１端部側から可動側第２端部に向かうに連れて可動部の内部空間が大きくなるように形成される。このため、可動部のうち収容空間と連通する部分の内部空間を大きく形成することができる。これにより、支持軸を回転軸として可動部が回転することに伴って収容空間に対する可動部の角度が変化する場合であっても、可動部の内部空間と収容空間との連通部分付近において電線部材の通る空間が狭くなることを好適に抑制できる。 According to this configuration, by providing the inclined surface on the inner peripheral surface of the movable part, the internal space of the movable part becomes larger from the first end of the movable side toward the second end of the movable side. It is formed. For this reason, the internal space of the portion of the movable part that communicates with the accommodation space can be formed to be large. As a result, even if the angle of the movable part with respect to the accommodation space changes as the movable part rotates about the support shaft as the rotation axis, the electric wire member is It is possible to suitably suppress the narrowing of the space through which the objects pass.
　［９］本開示のワイヤハーネスは、上記［１］から［８］のいずれか１つに記載の外装部材と、前記外装部材を貫通する前記電線部材と、を備える。
　この構成によれば、上記の外装部材と同様の作用効果を奏することができる。 [9] A wire harness of the present disclosure includes the exterior member according to any one of [1] to [8] above, and the electric wire member that passes through the exterior member.
According to this configuration, the same effects as those of the above-mentioned exterior member can be achieved.
　［１０］上記［９］において、前記外装部材を取付対象に固定するクランプを更に備え、前記保持部材は、前記保持部と一体に形成された第２筒状部を有し、前記第２筒状部は、前記保持部の軸方向の一端部から前記可動部から離れる方向に延びるように形成されており、前記クランプは、前記第２筒状部の外周面に取り付けられていることが好ましい。 [10] In the above [9], further comprising a clamp for fixing the exterior member to an attachment target, the holding member has a second cylindrical part formed integrally with the holding part, and the second cylindrical part is formed integrally with the holding part. It is preferable that the shaped part is formed to extend in a direction away from the movable part from one end in the axial direction of the holding part, and the clamp is attached to an outer peripheral surface of the second cylindrical part. .
　この構成によれば、保持部と一体に形成された第２筒状部の外周面にクランプが取り付けられる。これにより、第２筒状部を取付対象に固定することができ、その第２筒状部と一体に形成された保持部を取付対象に固定することができる。 According to this configuration, the clamp is attached to the outer peripheral surface of the second cylindrical part that is formed integrally with the holding part. Thereby, the second cylindrical part can be fixed to the attachment target, and the holding part formed integrally with the second cylindrical part can be fixed to the attachment target.

The second cylindrical portion 61 has, for example, a constant inner diameter over the entire length of the second cylindrical portion 61 in the axial direction. The inner circumferential surface of the second cylindrical portion 61, that is, the inner circumferential surface of the accommodating portion 61X, is formed flat over the entire length of the second cylindrical portion 61 in the axial direction, for example. For example, the second cylindrical portion 61 is formed such that the radial thickness (thickness) of the holding member 60 is constant over the entire length of the second cylindrical portion 61 in the axial direction. For example, the second cylindrical portion 61 has a constant cross-sectional shape over the entire length of the second cylindrical portion 61 in the axial direction. The cross-sectional shape of the accommodating portion 61X along the inner circumferential surface is, for example, circular. The inner diameter of the second cylindrical portion 61 is, for example, formed to a size such that the movable portion 42 cannot be inserted thereinto.

It has two end portions 72. The holding side second end portion 72 is provided to face the movable member 40, for example.
　保持部６２は、例えば、全体として球状に形成されている。保持部６２の外周面は、例えば、球面状に形成されている。保持部６２は、例えば、第２筒状部６１よりも外形寸法が大きく形成されている。保持部６２は、例えば、第２筒状部６１よりも外径が大きく形成されている。保持部６２の外周面は、例えば、第２筒状部６１の外周面から径方向外側に膨らむように形成されている。 The holding portion 62 is, for example, formed into a spherical shape as a whole.

The inner diameter of the accommodating space 62X is, for example, larger than the inner diameter of the accommodating portion 61X. The housing space 62X is, for example, formed in a size that can accommodate the movable part 42 in a rotatable state with respect to the housing space 62X. The housing space 62X is set, for example, to a size that prevents the movable part 42 from coming out of the housing space 62X when the movable part 42 rotates with respect to the housing space 62X.

　保持部６２は、例えば、保持部６２の軸方向の全長にわたって保持部材６０の径方向の厚み（肉厚）が一定に形成されている。保持部６２の径方向の厚みは、例えば、第２筒状部６１の径方向の厚みと等しい。すなわち、本実施形態の保持部材６０は、保持部材６０の軸方向の全長にわたって径方向の厚みが一定に形成されている。保持部６２の径方向の厚みは、例えば、可動部４２の径方向の厚みよりも薄い。図６に示すように、保持部６２は、例えば、保持部６２の周方向の全周にわたって径方向の厚みが一定に形成されている。 The holding portion 62 is formed so that, for example, the radial thickness (thickness) of the holding member 60 is constant over the entire length of the holding portion 62 in the axial direction. The radial thickness of the holding portion 62 is, for example, equal to the radial thickness of the second cylindrical portion 61. That is, the holding member 60 of this embodiment has a constant thickness in the radial direction over the entire length of the holding member 60 in the axial direction.

　保持部６２は、例えば、１以上の軸受孔６３を有している。本実施形態の保持部６２は、２つの軸受孔６３を有している。２つの軸受孔６３の各々には、可動部材４０の支持軸４３が挿入される。各軸受孔６３は、保持部６２を厚み方向に貫通するように形成されている。図５に示すように、各軸受孔６３の貫通方向から見た平面形状は、支持軸４３の外形に対応した形状に形成されている。本実施形態の各軸受孔６３の貫通方向から見た平面形状は、円形状に形成されている。本実施形態の各軸受孔６３の内面は、各軸受孔６３の貫通方向から見たときに、円弧状に形成されている。各軸受孔６３は、支持軸４３を収容可能な大きさに形成されている。各軸受孔６３の内径は、例えば、円柱状をなす支持軸４３の外径よりも一回り大きく形成されている。各軸受孔６３は、例えば、保持部６２の軸方向の中間部に設けられている。 The holding part 62 has, for example, one or more bearing holes 63. The holding part 62 of this embodiment has two bearing holes 63. The support shaft 43 of the movable member 40 is inserted into each of the two bearing holes 63. Each bearing hole 63 is formed to penetrate through the holding portion 62 in the thickness direction. As shown in FIG. 5, the planar shape of each bearing hole 63 when viewed from the penetrating direction is formed in a shape corresponding to the outer shape of the support shaft 43. In this embodiment, each bearing hole 63 has a circular planar shape when viewed from the penetrating direction. The inner surface of each bearing hole 63 in this embodiment is formed in an arc shape when viewed from the penetrating direction of each bearing hole 63. Each bearing hole 63 is formed in a size that can accommodate the support shaft 43. The inner diameter of each bearing hole 63 is, for example, one size larger than the outer diameter of the support shaft 43 having a cylindrical shape. Each bearing hole 63 is provided, for example, at an intermediate portion of the holding portion 62 in the axial direction.
　保持部６２の軸方向の端面には、例えば、各軸受孔６３と連通するガイド孔６４が設けられている。各ガイド孔６４は、保持部６２の軸方向の端面から各軸受孔６３まで延びている。各ガイド孔６４は、保持側第２端部７２における収容空間６２Ｘの開口端から軸受孔６３まで延びている。各ガイド孔６４は、例えば、保持部６２を厚み方向に貫通するように形成されている。各ガイド孔６４のうち軸受孔６３とは反対側の端部は、例えば、保持部材６０の軸方向に開口している。換言すると、各ガイド孔６４は、保持部６２の軸方向の端面から軸受孔６３まで切り欠くように形成されている。各ガイド孔６４は、例えば、可動部材４０を保持部材６０に組み付ける際に、支持軸４３を軸受孔６３内に誘導するための案内経路として機能する。換言すると、可動部材４０を保持部材６０に組み付ける際には、支持軸４３がガイド孔６４を通じて軸受孔６３の内部に挿入される。 For example, a guide hole 64 communicating with each bearing hole 63 is provided in the axial end surface of the holding portion 62. Each guide hole 64 extends from the end surface of the holding portion 62 in the axial direction to each bearing hole 63. Each guide hole 64 extends from the open end of the accommodation space 62X in the holding side second end 72 to the bearing hole 63. Each guide hole 64 is formed, for example, to penetrate the holding portion 62 in the thickness direction. The end of each guide hole 64 on the opposite side from the bearing hole 63 is open in the axial direction of the holding member 60, for example. In other words, each guide hole 64 is formed so as to cut out from the end surface of the holding portion 62 in the axial direction to the bearing hole 63. Each guide hole 64 functions as a guide path for guiding the support shaft 43 into the bearing hole 63, for example, when assembling the movable member 40 to the holding member 60. In other words, when assembling the movable member 40 to the holding member 60, the support shaft 43 is inserted into the bearing hole 63 through the guide hole 64.
　各ガイド孔６４は、例えば、軸受孔６３側から保持部６２の軸方向の端面に向かうに連れて開口幅が大きくなるように形成されている。各ガイド孔６４は、例えば、互いに対向する一対の内面６５を有している。各ガイド孔６４は、例えば、軸受孔６３から離れるに連れて、一対の内面６５の間の間隔が広がるように形成されている。一対の内面６５は、例えば、軸受孔６３側から保持部６２の軸方向の端面に向かうに連れてガイド孔６４の開口幅が大きくなるように傾斜した斜面に形成されている。各内面６５は、例えば、円弧状に湾曲した曲面に形成されている。各内面６５は、例えば、支持軸４３を軸受孔６３内に誘導するためのガイド面として機能する。 Each guide hole 64 is formed, for example, so that the opening width increases from the bearing hole 63 side toward the axial end surface of the holding portion 62. Each guide hole 64 has, for example, a pair of inner surfaces 65 facing each other. Each guide hole 64 is formed, for example, so that the distance between the pair of inner surfaces 65 increases as the distance from the bearing hole 63 increases. The pair of inner surfaces 65 are formed, for example, on inclined surfaces such that the opening width of the guide hole 64 increases from the bearing hole 63 side toward the end surface of the holding portion 62 in the axial direction. Each inner surface 65 is formed, for example, into an arcuate curved surface. Each inner surface 65 functions as a guide surface for guiding the support shaft 43 into the bearing hole 63, for example.
　ここで、ガイド孔６４及び軸受孔６３では、例えば、ガイド孔６４と軸受孔６３とが連通する部分が最も開口幅が小さくなっている。ガイド孔６４と軸受孔６３とが連通する部分の開口幅は、例えば、支持軸４３の直径よりも小さく設定されている。ガイド孔６４の内面６５と軸受孔６３の内面との角部６６では、ガイド孔６４側の部分と軸受孔６３側の部分とが互いに反対向きの円弧状に湾曲している。角部６６のうちガイド孔６４側の部分は、軸受孔６３内に支持軸４３を挿入する際の支持軸４３の入口となる部分である。また、角部６６のうち軸受孔６３側の部分は、軸受孔６３内の支持軸４３が支持軸４３の外部に抜ける際の支持軸４３の出口となる部分である。角部６６のうちガイド孔６４側の部分は、Ｒ面取りされた形状、つまりＲ形状に形成されている。角部６６のうち軸受孔６３側の部分は、Ｒ面取りされていない。本実施形態の角部６６では、ガイド孔６４側の部分及び軸受孔６３側の部分のうちガイド孔６４側の部分のみがＲ形状に形成されている。すなわち、本実施形態の角部６６では、支持軸４３の入口側及び出口側のうち入口側のみがＲ形状に形成されている。 Here, in the guide hole 64 and the bearing hole 63, for example, the portion where the guide hole 64 and the bearing hole 63 communicate has the smallest opening width. The opening width of the portion where the guide hole 64 and the bearing hole 63 communicate is set to be smaller than the diameter of the support shaft 43, for example. At a corner 66 between the inner surface 65 of the guide hole 64 and the inner surface of the bearing hole 63, a portion on the guide hole 64 side and a portion on the bearing hole 63 side are curved in arc shapes in opposite directions. A portion of the corner portion 66 on the guide hole 64 side serves as an entrance for the support shaft 43 when the support shaft 43 is inserted into the bearing hole 63. Further, a portion of the corner portion 66 on the bearing hole 63 side is a portion that becomes an exit of the support shaft 43 when the support shaft 43 inside the bearing hole 63 exits to the outside of the support shaft 43. The portion of the corner portion 66 on the guide hole 64 side is formed into an R-chamfered shape, that is, an R-shape. The portion of the corner portion 66 on the bearing hole 63 side is not rounded. In the corner portion 66 of this embodiment, only the portion on the guide hole 64 side among the portion on the guide hole 64 side and the portion on the bearing hole 63 side is formed in an R shape. That is, in the corner portion 66 of this embodiment, only the inlet side of the inlet side and the outlet side of the support shaft 43 is formed into an R shape.

　図３に示すように、ワイヤハーネス１０は、例えば、外装部材３１を車体パネル等の取付対象１００に固定するクランプ９０を有している。クランプ９０は、例えば、保持部材６０の第２筒状部６１の外周面に取り付けられている。クランプ９０は、例えば、第２筒状部６１の軸方向の中間部に設けられている。クランプ９０は、例えば、第２筒状部６１の外周に嵌合する嵌合部９１と、取付対象１００に固定される固定部９２とを有している。嵌合部９１は、例えば、第２筒状部６１の外周を周方向全周にわたって包囲している。例えば、嵌合部９１が第２筒状部６１の外周に取り付けられるとともに固定部９２が取付対象１００に固定されることにより、保持部材６０が取付対象１００に固定される。クランプ９０は、例えば、金属製又は樹脂製である。 (Configuration of clamp 90)
As shown in FIG. 3, the wire harness 10 includes, for example, a clamp 90 that fixes the exterior member 31 to an attachment target 100 such as a vehicle body panel. The clamp 90 is attached to the outer peripheral surface of the second cylindrical portion 61 of the holding member 60, for example. The clamp 90 is provided, for example, at the middle portion of the second cylindrical portion 61 in the axial direction. The clamp 90 has, for example, a fitting part 91 that fits on the outer periphery of the second cylindrical part 61 and a fixing part 92 that is fixed to the attachment target 100. For example, the fitting portion 91 surrounds the entire outer periphery of the second cylindrical portion 61 in the circumferential direction. For example, the holding member 60 is fixed to the attachment target 100 by attaching the fitting part 91 to the outer periphery of the second cylindrical part 61 and fixing the fixing part 92 to the attachment target 100. The clamp 90 is made of metal or resin, for example.
　（規制部材９５，９６の構成）
　ワイヤハーネス１０は、例えば、外装部材３１に対する筒状部材３２の相対移動を規制する規制部材９５を有している。ワイヤハーネス１０は、例えば、外装部材３１に対する筒状部材３３の相対移動を規制する規制部材９６を有している。規制部材９５，９６としては、例えば、結束バンド、カシメリングや粘着テープ等を用いることができる。本実施形態の規制部材９５，９６は、粘着テープである。なお、図３以外の図面では、図面の簡略化のために、クランプ９０及び規制部材９５，９６の図示を省略している。 (Configuration of regulating members 95, 96)
The wire harness 10 includes, for example, a regulating member 95 that regulates relative movement of the cylindrical member 32 with respect to the exterior member 31. The wire harness 10 includes, for example, a regulating member 96 that regulates relative movement of the cylindrical member 33 with respect to the exterior member 31. As the regulating members 95 and 96, for example, a binding band, a crimping ring, an adhesive tape, or the like can be used. The regulating members 95 and 96 of this embodiment are adhesive tapes. In addition, in drawings other than FIG. 3, illustration of the clamp 90 and the regulating members 95 and 96 is omitted for simplification of the drawings.
　規制部材９５は、例えば、第１筒状部４１の長さ方向の端部のうち可動部４２とは反対側に設けられた端部の外周面から筒状部材３２の外周面にわたって巻き付けられている。規制部材９６は、例えば、第２筒状部６１の長さ方向の端部のうち保持部６２とは反対側に設けられた端部の外周面から筒状部材３３の外周面にわたって巻き付けられている。 For example, the regulating member 95 is wound around the outer circumferential surface of the cylindrical member 32 from the outer circumferential surface of the end provided on the opposite side of the movable section 42 among the longitudinal ends of the first cylindrical section 41 . There is. For example, the regulating member 96 is wound around the outer circumferential surface of the cylindrical member 33 from the outer circumferential surface of the end provided on the opposite side of the holding portion 62 among the longitudinal ends of the second cylindrical portion 61 . There is.
　（可動部材４０と保持部材６０との組み付け）
　図２に示すように、可動部材４０を保持部材６０に組み付ける際には、可動部材４０の可動部４２が保持部６２の内側に嵌合される。このとき、可動部４２の外周面に設けられた支持軸４３が保持部６２の軸受孔６３に挿入されるように、可動部４２が保持部６２の内側に嵌合される。支持軸４３は、保持部６２のガイド孔６４を通じて軸受孔６３の内部に挿入される。具体的には、支持軸４３は、ガイド孔６４の内面６５に沿って軸受孔６３に誘導される。このとき、ガイド孔６４と連通する部分の軸受孔６３の開口端から軸受孔６３内に支持軸４３が挿入されると、保持部６２が弾性変形して軸受孔６３の開口端における開口幅が大きくなる。また、保持側第２端部７２における収容空間６２Ｘの開口端から可動部４２が挿入されると、保持部６２が弾性変形して収容空間６２Ｘの開口幅が大きくなる。このとき、保持部６２の軸方向の端面にガイド孔６４を切り欠き状に設けたことにより、保持部６２を好適に弾性変形させることができ、収容空間６２Ｘの開口幅を好適に大きくすることができる。そして、支持軸４３が軸受孔６３に収容されるとともに可動部４２が収容空間６２Ｘに収容されると、保持部６２が元の形状に戻ろうと弾性復帰する。これにより、軸受孔６３の開口端における内径が支持軸４３の外径よりも小さく形成されるとともに、保持側第２端部７２における収容空間６２Ｘの内径が可動部４２の外径よりも小さく形成される。このため、軸受孔６３から支持軸４３が抜けることを抑制できるとともに、収容空間６２Ｘから可動部４２が抜けることを抑制できる。 (Assembling of movable member 40 and holding member 60)
As shown in FIG. 2, when assembling the movable member 40 to the holding member 60, the movable part 42 of the movable member 40 is fitted inside the holding part 62. At this time, the movable part 42 is fitted inside the holding part 62 so that the support shaft 43 provided on the outer peripheral surface of the movable part 42 is inserted into the bearing hole 63 of the holding part 62. The support shaft 43 is inserted into the bearing hole 63 through the guide hole 64 of the holding part 62. Specifically, the support shaft 43 is guided into the bearing hole 63 along the inner surface 65 of the guide hole 64 . At this time, when the support shaft 43 is inserted into the bearing hole 63 from the open end of the bearing hole 63 that communicates with the guide hole 64, the holding part 62 is elastically deformed and the opening width at the open end of the bearing hole 63 is reduced. growing. Moreover, when the movable part 42 is inserted from the open end of the accommodation space 62X at the holding-side second end 72, the holding part 62 is elastically deformed and the opening width of the accommodation space 62X increases. At this time, by providing the guide hole 64 in the shape of a notch in the axial end face of the holding part 62, the holding part 62 can be suitably elastically deformed, and the opening width of the accommodation space 62X can be suitably enlarged. Can be done. When the support shaft 43 is accommodated in the bearing hole 63 and the movable portion 42 is accommodated in the accommodation space 62X, the holding portion 62 elastically returns to its original shape. As a result, the inner diameter of the bearing hole 63 at the open end is smaller than the outer diameter of the support shaft 43, and the inner diameter of the accommodation space 62X at the holding side second end 72 is smaller than the outer diameter of the movable part 42. be done. For this reason, it is possible to suppress the support shaft 43 from coming off from the bearing hole 63, and it is also possible to suppress the movable part 42 from coming off from the accommodation space 62X.
　可動部４２が収容空間６２Ｘに収容されるとともに支持軸４３が軸受孔６３に収容されると、可動部４２が支持軸４３を回転軸として回転可能に収容空間６２Ｘ内に保持される。例えば、図２に示すように、可動部４２は、支持軸４３を回転軸として図中上下に回転可能に収容空間６２Ｘ内に保持される。例えば、可動部４２は、支持軸４３を回転軸として、保持部材６０の軸方向と交差する方向に可動自在に保持部材６０に保持される。なお、可動部４２は、２つの支持軸４３が並ぶ方向には可動しないように構成されている。このような可動部４２に第１筒状部４１が一体に形成されているため、第１筒状部４１は保持部材６０に対して可動自在に保持部材６０に保持される。例えば、第１筒状部４１は、支持軸４３を回転軸として図中上下に回転可能に保持部材６０に保持される。これにより、保持部材６０の外部に引き出される第１筒状部４１の引き出し方向を容易に可変することができる。このとき、電線部材２０は第１筒状部４１の内部に収容されているため、第１筒状部４１の引き出し方向の変更に合わせて、保持部材６０の外部に引き出される電線部材２０の引き出し方向を容易に可変することができる。このため、例えば図３に示した屈曲部１０Ｃのように、ワイヤハーネス１０の経路が急峻に曲げられる部分であっても、その曲げ状態に合わせて第１筒状部４１及び電線部材２０の引き出し方向を容易に調整することができる。 When the movable part 42 is accommodated in the accommodation space 62X and the support shaft 43 is accommodated in the bearing hole 63, the movable part 42 is held in the accommodation space 62X so as to be rotatable about the support shaft 43 as the rotation axis. For example, as shown in FIG. 2, the movable part 42 is held in the accommodation space 62X so as to be rotatable up and down in the figure with the support shaft 43 as a rotation axis. For example, the movable portion 42 is held by the holding member 60 so as to be movable in a direction intersecting the axial direction of the holding member 60 with the support shaft 43 as a rotation axis. Note that the movable portion 42 is configured not to move in the direction in which the two support shafts 43 are lined up. Since the first cylindrical portion 41 is integrally formed with such a movable portion 42, the first cylindrical portion 41 is held by the holding member 60 so as to be movable relative to the holding member 60. For example, the first cylindrical portion 41 is held by the holding member 60 so as to be rotatable up and down in the figure with the support shaft 43 as the rotation axis. Thereby, the direction in which the first cylindrical portion 41 is pulled out to the outside of the holding member 60 can be easily varied. At this time, since the electric wire member 20 is housed inside the first cylindrical part 41, the electric wire member 20 is pulled out to the outside of the holding member 60 in accordance with the change in the drawing direction of the first cylindrical part 41. The direction can be easily changed. For this reason, even if the route of the wire harness 10 is a part where the wire harness 10 is sharply bent, for example, like the bending part 10C shown in FIG. The direction can be easily adjusted.
　ここで、収容空間６２Ｘから引き出される第１筒状部４１の可動域は、例えば、保持部６２の軸方向の端部と第１筒状部４１との接触により規制される。このとき、図４に示すように、保持側第２端部７２における保持部６２の内面は、収容空間６２Ｘから保持部６２の軸方向の端面に向かうに連れて開口幅が広がるように傾斜面７３に形成されている。これにより、収容空間６２Ｘから引き出される第１筒状部４１の可動域を広く設定することができる。 Here, the range of motion of the first cylindrical portion 41 pulled out from the accommodation space 62X is restricted by, for example, contact between the axial end of the holding portion 62 and the first cylindrical portion 41. At this time, as shown in FIG. 4, the inner surface of the holding part 62 at the holding side second end part 72 has an inclined surface such that the opening width increases from the accommodation space 62X toward the end surface of the holding part 62 in the axial direction. 73. Thereby, the movable range of the first cylindrical portion 41 pulled out from the accommodation space 62X can be set wide.
　次に、本実施形態の作用効果を説明する。
　（１）可動部材４０の可動部４２が保持部６２の収容空間６２Ｘに収容されるとともに、可動部材４０の支持軸４３が保持部６２の軸受孔６３に挿入される。このとき、可動部４２は、支持軸４３を回転軸として保持部６２に対して回転可能に収容空間６２Ｘ内に収容される。これにより、可動部４２を、収容空間６２Ｘ内において、支持軸４３を回転軸として保持部６２に対して自由に回転させることができる。このような可動部４２に第１筒状部４１が一体に形成されている。このため、保持部材６０の外部に設けられた第１筒状部４１を、支持軸４３を回転軸として保持部６２に対して自由に回転させることができる。これにより、保持部材６０の外部に引き出される第１筒状部４１の引き出し方向を容易に可変することができる。したがって、ワイヤハーネス１０の経路が急峻に曲げられる場合であっても、その曲げ部分の経路に合わせて第１筒状部４１の引き出し方向を容易に調整することができる。この結果、ワイヤハーネス１０の経路が急峻に曲げられる場合であっても、その曲げ部分の経路に合わせて外装部材３１を容易に変形させることができるため、狭いスペースであっても外装部材３１を有するワイヤハーネス１０を好適に配索することができる。これにより、ワイヤハーネス１０の配索性を向上できる。 Next, the effects of this embodiment will be explained.
(1) The movable part 42 of the movable member 40 is accommodated in the accommodation space 62X of the holding part 62, and the support shaft 43 of the movable member 40 is inserted into the bearing hole 63 of the holding part 62. At this time, the movable part 42 is accommodated in the accommodation space 62X so as to be rotatable with respect to the holding part 62 using the support shaft 43 as a rotation axis. Thereby, the movable part 42 can be freely rotated with respect to the holding part 62 within the accommodation space 62X using the support shaft 43 as a rotation axis. The first cylindrical portion 41 is integrally formed with such a movable portion 42 . Therefore, the first cylindrical part 41 provided outside the holding member 60 can be freely rotated with respect to the holding part 62 using the support shaft 43 as the rotation axis. Thereby, the direction in which the first cylindrical portion 41 is pulled out to the outside of the holding member 60 can be easily varied. Therefore, even if the path of the wire harness 10 is sharply bent, the direction in which the first cylindrical portion 41 is pulled out can be easily adjusted in accordance with the path of the bent portion. As a result, even if the path of the wire harness 10 is sharply bent, the exterior member 31 can be easily deformed to match the path of the bent portion, so the exterior member 31 can be easily deformed even in a narrow space. The wire harness 10 having the above structure can be suitably routed. Thereby, the ease of wiring the wire harness 10 can be improved.
　（２）さらに、外装部材３１のうち保持部材６０の外部に引き出される部分には第１筒状部４１が設けられている。このため、外装部材３１の内部に電線部材２０が収容された場合に、保持部材６０の外部に引き出される電線部材２０の外周が第１筒状部４１により包囲される。これにより、保持部材６０の外部に引き出される電線部材２０の経路を第１筒状部４１により規制することができる。この結果、ワイヤハーネス１０と周辺部品との干渉を好適に抑制できるため、狭いスペースであってもワイヤハーネス１０を好適に配索することができる。これにより、ワイヤハーネス１０の配索性をより向上できる。 (2) Furthermore, a first cylindrical portion 41 is provided in a portion of the exterior member 31 that is pulled out to the outside of the holding member 60. Therefore, when the electric wire member 20 is housed inside the exterior member 31, the outer periphery of the electric wire member 20 pulled out to the outside of the holding member 60 is surrounded by the first cylindrical portion 41. Thereby, the path of the electric wire member 20 drawn out from the holding member 60 can be regulated by the first cylindrical portion 41 . As a result, interference between the wire harness 10 and peripheral components can be suitably suppressed, so that the wire harness 10 can be suitably routed even in a narrow space. Thereby, the ease of wiring the wire harness 10 can be further improved.
　（３）可動部４２に支持軸４３を設けるとともに、保持部６２に支持軸４３が挿入される軸受孔６３を設けるようにし、支持軸４３を回転軸に設定するようにした。このため、支持軸４３の形成位置に応じて、可動部４２が可動できる方向を任意の方向に設定することができる。換言すると、支持軸４３の形成位置に応じて、可動部４２が可動できない方向を任意の方向に設定することができる。これにより、可動部４２が不要な方向に可動することを好適に抑制できる。 (3) The movable part 42 is provided with the support shaft 43, and the holding part 62 is provided with a bearing hole 63 into which the support shaft 43 is inserted, so that the support shaft 43 is set as a rotating shaft. Therefore, depending on the formation position of the support shaft 43, the direction in which the movable portion 42 can move can be set to any direction. In other words, depending on the formation position of the support shaft 43, the direction in which the movable portion 42 cannot move can be set to any direction. Thereby, it is possible to suitably suppress the movable portion 42 from moving in unnecessary directions.
　（４）保持部６２の軸方向の端面を切り欠くようにガイド孔６４が形成される。このガイド孔６４を通じて軸受孔６３に支持軸４３を挿入することができる。このとき、ガイド孔６４は、軸受孔６３側から保持部６２の軸方向の端面に向かうに連れて開口幅が大きくなるように傾斜して形成されている。このため、支持軸４３を軸受孔６３に挿入する際には、支持軸４３がガイド孔６４の斜面に沿って、保持部６２の軸方向の端面から軸受孔６３に向かって誘導される。これにより、支持軸４３を軸受孔６３に容易に挿入することができる。 (4) The guide hole 64 is formed by cutting out the end surface of the holding portion 62 in the axial direction. The support shaft 43 can be inserted into the bearing hole 63 through this guide hole 64. At this time, the guide hole 64 is formed to be inclined so that the opening width increases from the bearing hole 63 side toward the end surface of the holding portion 62 in the axial direction. Therefore, when inserting the support shaft 43 into the bearing hole 63, the support shaft 43 is guided toward the bearing hole 63 from the axial end surface of the holding portion 62 along the slope of the guide hole 64. Thereby, the support shaft 43 can be easily inserted into the bearing hole 63.
　（５）ガイド孔６４の内面６５と軸受孔６３の内面との角部６６、つまりガイド孔６４と軸受孔６３とが連通する部分において、支持軸４３を軸受孔６３に挿入する際の入口となるガイド孔６４側の部分のみがＲ形状に形成される。これにより、ガイド孔６４の内面６５に形成されたＲ形状に沿って支持軸４３を軸受孔６３に向かってスムーズに誘導することができる。また、ガイド孔６４の内面６５と軸受孔６３の内面との角部６６において、支持軸４３が軸受孔６３から抜ける際の出口となる軸受孔６３側の部分がＲ形状に形成されていない。これにより、軸受孔６３の内部からガイド孔６４に向かう支持軸４３の移動を角部６６によって好適に規制できるため、軸受孔６３から支持軸４３が抜けることを好適に抑制できる。 (5) A corner 66 between the inner surface 65 of the guide hole 64 and the inner surface of the bearing hole 63, that is, the portion where the guide hole 64 and the bearing hole 63 communicate, serves as an entrance when inserting the support shaft 43 into the bearing hole 63. Only the portion on the guide hole 64 side is formed in an R shape. Thereby, the support shaft 43 can be smoothly guided toward the bearing hole 63 along the R shape formed on the inner surface 65 of the guide hole 64. Furthermore, at the corner 66 between the inner surface 65 of the guide hole 64 and the inner surface of the bearing hole 63, the portion on the bearing hole 63 side that serves as an exit when the support shaft 43 exits from the bearing hole 63 is not formed in an R shape. Thereby, the movement of the support shaft 43 from the inside of the bearing hole 63 toward the guide hole 64 can be suitably restricted by the corner portion 66, so that it is possible to suitably suppress the support shaft 43 from coming out of the bearing hole 63.
　（６）可動部４２に２つの支持軸４３を設けた。２つの支持軸４３を、可動部４２の周方向において、互いにπ［ｒａｄ］ずれた位置に設けた。この構成によれば、収容空間６２Ｘの内部において、２つの支持軸４３が並んでいる方向に可動部４２が可動することを好適に抑制できる。 (6) Two support shafts 43 were provided in the movable part 42. The two support shafts 43 were provided at positions shifted by π [rad] from each other in the circumferential direction of the movable portion 42 . According to this configuration, it is possible to suitably suppress the movement of the movable part 42 in the direction in which the two support shafts 43 are lined up inside the accommodation space 62X.
　（７）可動部４２の径方向の厚みが、第１筒状部４１の径方向の厚みよりも厚く形成されている。これにより、可動部４２の厚みと第１筒状部４１の厚みとが等しい場合に比べて、可動部４２の剛性を向上させることができ、可動部４２が変形することを抑制できる。例えば、保持部６２を弾性変形させながら収容空間６２Ｘに可動部４２を挿入する際に、可動部４２が変形することを抑制できる。 (7) The radial thickness of the movable part 42 is formed to be thicker than the radial thickness of the first cylindrical part 41. Thereby, compared to the case where the thickness of the movable part 42 and the thickness of the first cylindrical part 41 are equal, the rigidity of the movable part 42 can be improved and deformation of the movable part 42 can be suppressed. For example, when inserting the movable part 42 into the housing space 62X while elastically deforming the holding part 62, deformation of the movable part 42 can be suppressed.
　（８）ところで、ワイヤハーネス１０に屈曲部１０Ｃを形成する際には、例えば、まず、可動部材４０と保持部材６０とが直線状に延びるように組み付けられた状態の外装部材３１の内部に電線部材２０が挿入される。次に、支持軸４３を回転軸として保持部材６０に対して可動部材４０を回転させることにより、外装部材３１が屈曲される。このとき、外装部材３１の内部に収容された電線部材２０が外装部材３１と一緒に屈曲されることにより、ワイヤハーネス１０に屈曲部１０Ｃが形成される。この場合の電線部材２０は、回転する可動部材４０の内周面近傍を起点にして屈曲される。このため、可動部４２の内周面には、電線部材２０が接触しやすい。これに対し、可動部４２の剛性が高められているため、電線部材２０との接触に起因して可動部４２が損傷することを好適に抑制できる。 (8) By the way, when forming the bent portion 10C in the wire harness 10, for example, first, the electric wire Member 20 is inserted. Next, by rotating the movable member 40 with respect to the holding member 60 using the support shaft 43 as a rotation axis, the exterior member 31 is bent. At this time, the electric wire member 20 housed inside the exterior member 31 is bent together with the exterior member 31, thereby forming a bent portion 10C in the wire harness 10. In this case, the electric wire member 20 is bent starting from the vicinity of the inner peripheral surface of the rotating movable member 40. Therefore, the electric wire member 20 easily comes into contact with the inner circumferential surface of the movable portion 42 . On the other hand, since the rigidity of the movable part 42 is increased, damage to the movable part 42 due to contact with the electric wire member 20 can be suitably suppressed.
　（９）可動部４２の内周面に傾斜面５３を設けた。これにより、可動側第１端部５１側から可動側第２端部５２に向かうに連れて可動部４２の内部空間４２Ｘが大きくなるように形成される。このため、可動部４２の内部空間４２Ｘのうち収容空間６２Ｘと連通する部分の空間を大きく形成することができる。これにより、可動部４２が回転することに伴って収容空間６２Ｘに対する可動部４２の角度が変化する場合であっても、可動部４２の内部空間４２Ｘと収容空間６２Ｘとの連通部分付近において電線部材２０の通る空間が狭くなることを好適に抑制できる。 (9) An inclined surface 53 is provided on the inner peripheral surface of the movable part 42. Thereby, the internal space 42X of the movable part 42 is formed to become larger from the movable first end 51 side toward the movable second end 52. For this reason, it is possible to form a large space in a portion of the internal space 42X of the movable portion 42 that communicates with the accommodation space 62X. As a result, even if the angle of the movable part 42 with respect to the accommodation space 62X changes as the movable part 42 rotates, the electric wire member may It is possible to suitably suppress narrowing of the space through which 20 passes.
　（１０）保持部材６０の第２筒状部６１の外周面にクランプ９０が取り付けられている。これにより、第２筒状部６１を取付対象１００に固定することができ、その第２筒状部６１と一体に形成された保持部６２を取付対象１００に固定することができる。 (10) A clamp 90 is attached to the outer peripheral surface of the second cylindrical portion 61 of the holding member 60. Thereby, the second cylindrical part 61 can be fixed to the attachment target 100, and the holding part 62 formed integrally with the second cylindrical part 61 can be fixed to the attachment target 100.
　（１１）筒状部材３２，３３を、外装部材３１の外部のみに設けるようにした。このため、筒状部材３２，３３は、屈曲部１０Ｃにおける電線部材２０の外周を包囲する外装部材３１の内部に挿入されない。したがって、屈曲部１０Ｃの経路に沿って屈曲されることに起因して筒状部材３２，３３に割れ等の損傷が発生することを防止できる。 (11) The cylindrical members 32 and 33 are provided only on the outside of the exterior member 31. Therefore, the cylindrical members 32 and 33 are not inserted into the exterior member 31 surrounding the outer periphery of the electric wire member 20 at the bent portion 10C. Therefore, it is possible to prevent damage such as cracks from occurring in the cylindrical members 32 and 33 due to bending along the path of the bent portion 10C.
　（他の実施形態）
　上記実施形態は、以下のように変更して実施することができる。上記実施形態及び以下の変更例は、技術的に矛盾しない範囲で互いに組み合わせて実施することができる。 (Other embodiments)
The above embodiment can be modified and implemented as follows. The above embodiment and the following modification examples can be implemented in combination with each other within a technically consistent range.
　・上記実施形態の保持部材６０の構造は適宜変更することができる。
　例えば図７～図９に示すように、保持部６２に、可動部材４０の可動域を拡大する１以上の拡大空間８０を設けるようにしてもよい。なお、図７～図９には、相互に直交するＸ軸、Ｙ軸、Ｚ軸を図示している。図８に示すように、本変更例の保持部６２は、２つの拡大空間８０を有している。各拡大空間８０は、収容空間６２Ｘに連通している。各拡大空間８０は、第１筒状部４１が挿入可能に形成されている。各拡大空間８０は、例えば、収容空間６２Ｘの一部を切り欠くように形成されている。各拡大空間８０は、例えば、保持部材６０の軸方向と交差する方向に開口している。各拡大空間８０は、例えば、収容空間６２Ｘと保持部材６０の外部とを連通するように形成されている。なお、拡大空間８０により切り欠かれた収容空間６２Ｘの大きさは、その収容空間６２Ｘから可動部４２が抜けない大きさに設定されている。換言すると、収容空間６２Ｘの大きさがその収容空間６２Ｘから可動部４２が抜けない大きさに維持されるように、拡大空間８０の大きさが設定されている。 - The structure of the holding member 60 of the above embodiment can be changed as appropriate.
For example, as shown in FIGS. 7 to 9, the holding portion 62 may be provided with one or more expansion spaces 80 that expand the range of motion of the movable member 40. Note that FIGS. 7 to 9 illustrate mutually orthogonal X, Y, and Z axes. As shown in FIG. 8, the holding section 62 of this modified example has two enlarged spaces 80. Each enlarged space 80 communicates with the accommodation space 62X. Each expanded space 80 is formed into which the first cylindrical portion 41 can be inserted. Each enlarged space 80 is formed, for example, by cutting out a part of the accommodation space 62X. Each enlarged space 80 opens, for example, in a direction intersecting the axial direction of the holding member 60. Each enlarged space 80 is formed, for example, so that the accommodation space 62X and the outside of the holding member 60 communicate with each other. Note that the size of the accommodation space 62X cut out by the enlarged space 80 is set to a size that prevents the movable part 42 from coming out of the accommodation space 62X. In other words, the size of the expansion space 80 is set so that the size of the accommodation space 62X is maintained at a size that prevents the movable part 42 from coming off from the accommodation space 62X.
　各拡大空間８０は、例えば、保持部６２の軸方向の端部、具体的には保持側第２端部７２に設けられた切り欠きである。各拡大空間８０は、例えば、保持部６２の軸方向の端面から収容空間６２Ｘの軸方向の一部まで切り欠くように形成されている。各拡大空間８０は、例えば、保持部材６０の軸方向に沿って延びている。各拡大空間８０は、例えば、保持部６２の軸方向の端面から収容空間６２Ｘの軸方向の半分程度の位置まで延びている。各拡大空間８０は、例えば、保持部６２の周壁を切り欠くように形成されている。各拡大空間８０は、例えば、保持部６２の周壁を径方向に貫通するように形成されている。各拡大空間８０は、例えば、保持部６２の軸方向と直交する方向に開口するとともに、保持部６２の軸方向に開口している。ここで、拡大空間８０は、保持部６２の軸方向に沿った長さ方向と、その長さ方向と直交する幅方向と、それら長さ方向及び幅方向の双方と直交する貫通方向とに延在している。拡大空間８０の長さ方向は、Ｘ軸に沿って延びている。拡大空間８０の幅方向は、Ｙ軸に沿って延びている。拡大空間８０の貫通方向は、Ｚ軸に沿って延びている。２つの拡大空間８０は、例えば、拡大空間８０の貫通方向から見た平面視において、互いに重なるように設けられている。２つの拡大空間８０は、例えば、互いに同じ形状に形成されている。各拡大空間８０は、例えば、保持部６２の周方向において、軸受孔６３及びガイド孔６４と異なる位置に設けられている。各拡大空間８０は、例えば、軸受孔６３から保持部６２の周方向に約π／２［ｒａｄ］ずれた位置に設けられている。 Each expansion space 80 is, for example, a notch provided in the axial end of the holding part 62, specifically, in the holding-side second end 72. Each enlarged space 80 is formed, for example, by cutting out from the axial end face of the holding part 62 to a part of the accommodation space 62X in the axial direction. Each enlarged space 80 extends, for example, along the axial direction of the holding member 60. Each expanded space 80 extends, for example, from the end surface of the holding portion 62 in the axial direction to a position about half of the accommodation space 62X in the axial direction. Each enlarged space 80 is formed, for example, by cutting out the peripheral wall of the holding portion 62. Each expanded space 80 is formed, for example, to radially penetrate the peripheral wall of the holding portion 62. Each expansion space 80 opens in a direction perpendicular to the axial direction of the holding part 62, and also opens in the axial direction of the holding part 62, for example. Here, the expansion space 80 extends in the length direction along the axial direction of the holding part 62, in the width direction perpendicular to the length direction, and in the penetrating direction perpendicular to both the length direction and the width direction. There is. The length direction of the enlarged space 80 extends along the X axis. The width direction of the enlarged space 80 extends along the Y-axis. The penetrating direction of the enlarged space 80 extends along the Z-axis. The two enlarged spaces 80 are provided so as to overlap each other, for example, in a plan view seen from the penetrating direction of the enlarged spaces 80. The two enlarged spaces 80 are, for example, formed to have the same shape. Each enlarged space 80 is provided, for example, at a different position from the bearing hole 63 and the guide hole 64 in the circumferential direction of the holding portion 62. Each enlarged space 80 is provided, for example, at a position offset from the bearing hole 63 by about π/2 [rad] in the circumferential direction of the holding portion 62.
　図９に示すように、各拡大空間８０の貫通方向から見た平面形状（以下、単に「拡大空間８０の平面形状」ともいう。）は、例えば、四角形に形成されている。各拡大空間８０の平面形状は、例えば、拡大空間８０の長さ方向の端部のうち第２筒状部６１側（図中右側）の端部８１における上記四角形の角部８２が丸く形成されている。角部８２は、例えば、Ｒ面取りされたＲ形状に形成されている。本変更例の角部８２は、比較的大きな曲率半径を有する曲面に形成されている。本変更例の端部８１は、半円状に形成されている。端部８１は、例えば、円筒状をなす第１筒状部４１の外周面に沿った半円状に形成されている。これにより、本変更例の各拡大空間８０の平面形状は、半長円形に形成されている。ここで、本明細書における「長円形」は、２つの等しい長さの平行線と２つの半円形からなる角丸長方形状である。 As shown in FIG. 9, the planar shape of each enlarged space 80 viewed from the penetrating direction (hereinafter also simply referred to as "the planar shape of the enlarged space 80") is, for example, square. The planar shape of each expansion space 80 is such that, for example, the rectangular corner 82 at the end 81 on the second cylindrical portion 61 side (the right side in the figure) among the lengthwise ends of the expansion space 80 is rounded. ing. The corner portion 82 is, for example, formed into an R-shape with an R-chamfer. The corner portion 82 of this modification is formed into a curved surface having a relatively large radius of curvature. The end portion 81 of this modification is formed in a semicircular shape. The end portion 81 is formed, for example, in a semicircular shape along the outer peripheral surface of the first cylindrical portion 41 . As a result, the planar shape of each enlarged space 80 in this modification example is formed into a semi-ellipse. Here, the "ellipse" in this specification is a rounded rectangular shape consisting of two parallel lines of equal length and two semicircles.
　各拡大空間８０の幅方向（図中上下方向）に沿う最大寸法は、例えば、第１筒状部４１の幅方向（図中上下方向）に沿う最大寸法よりも大きく形成されている。各拡大空間８０の幅方向に沿う最大寸法は、例えば、球状の可動部４２の直径よりも小さく形成されている。なお、端部８１の幅方向に沿う寸法は、拡大空間８０の幅方向に沿う最大寸法よりも小さく形成されている。 The maximum dimension of each expanded space 80 along the width direction (vertical direction in the drawing) is, for example, larger than the maximum dimension along the width direction (vertical direction in the drawing) of the first cylindrical portion 41. The maximum dimension of each expanded space 80 along the width direction is, for example, smaller than the diameter of the spherical movable portion 42. Note that the dimension of the end portion 81 along the width direction is smaller than the maximum dimension of the enlarged space 80 along the width direction.
　図７に示すように、可動部材４０を保持部材６０に組み付ける際には、可動部材４０の可動部４２が保持部６２の内側に嵌合される。このとき、可動部４２の外周面に設けられた支持軸４３が保持部６２の軸受孔６３に挿入されるように、可動部４２が保持部６２の内側に嵌合される。このとき、ガイド孔６４と連通する部分の軸受孔６３の開口端から軸受孔６３内に挿入されると、保持部６２が弾性変形して軸受孔６３の開口端における開口幅が大きくなる。また、保持側第２端部７２における収容空間６２Ｘの開口端から可動部４２が挿入されると、保持部６２が弾性変形して収容空間６２Ｘの開口径が大きくなる。このとき、保持部６２にガイド孔６４及び拡大空間８０を切り欠き状に設けたことにより、保持部６２を好適に弾性変形させることができ、収容空間６２Ｘの開口径を好適に大きくすることができる。支持軸４３が軸受孔６３に収容されるとともに可動部４２が収容空間６２Ｘに収容されると、保持部６２が元の形状に戻ろうと弾性復帰する。これにより、軸受孔６３の開口端における内径が支持軸４３の外径よりも小さく形成されるとともに、保持側第２端部７２における収容空間６２Ｘの内径が可動部４２の外径よりも小さく形成される。このため、軸受孔６３から支持軸４３が抜けることを抑制できるとともに、収容空間６２Ｘから可動部４２が抜けることを抑制できる。 As shown in FIG. 7, when assembling the movable member 40 to the holding member 60, the movable part 42 of the movable member 40 is fitted inside the holding part 62. At this time, the movable part 42 is fitted inside the holding part 62 so that the support shaft 43 provided on the outer peripheral surface of the movable part 42 is inserted into the bearing hole 63 of the holding part 62. At this time, when the holding portion 62 is inserted into the bearing hole 63 from the open end of the bearing hole 63 in the portion communicating with the guide hole 64, the holding portion 62 is elastically deformed and the opening width at the open end of the bearing hole 63 increases. Further, when the movable part 42 is inserted from the open end of the accommodation space 62X at the holding side second end 72, the holding part 62 is elastically deformed and the opening diameter of the accommodation space 62X increases. At this time, by providing the guide hole 64 and the enlarged space 80 in the shape of a notch in the holding part 62, the holding part 62 can be suitably elastically deformed, and the opening diameter of the accommodation space 62X can be suitably enlarged. can. When the support shaft 43 is accommodated in the bearing hole 63 and the movable portion 42 is accommodated in the accommodation space 62X, the holding portion 62 elastically returns to its original shape. As a result, the inner diameter of the bearing hole 63 at the open end is smaller than the outer diameter of the support shaft 43, and the inner diameter of the accommodation space 62X at the holding side second end 72 is smaller than the outer diameter of the movable part 42. be done. For this reason, it is possible to suppress the support shaft 43 from coming off from the bearing hole 63, and it is also possible to suppress the movable part 42 from coming off from the accommodation space 62X.
　可動部４２が可動部４２に収容されるとともに支持軸４３が軸受孔６３に収容されると、可動部４２が支持軸４３を回転軸として回転可能に収容空間６２Ｘ内に保持される。例えば、可動部４２は、支持軸４３を回転軸として図中上下に回転可能に収容空間６２Ｘ内に保持される。例えば、可動部４２は、支持軸４３を回転軸として、保持部材６０の軸方向と交差する方向に可動自在に保持部材６０に保持される。このような可動部４２に第１筒状部４１が一体に形成されているため、第１筒状部４１は保持部材６０に対して可動自在に保持部材６０に保持される。例えば、第１筒状部４１は、支持軸４３を回転軸として図中上下に回転可能に保持部材６０に保持される。これにより、保持部材６０の外部に引き出される第１筒状部４１の引き出し方向を容易に可変することができる。このとき、電線部材２０は第１筒状部４１の内部に収容されているため、第１筒状部４１の引き出し方向の変更に合わせて、保持部材６０の外部に引き出される電線部材２０の引き出し方向を容易に調整することができる。このため、例えば図７に示すように、ワイヤハーネス１０の経路が急峻に曲げられる場合であっても、その曲げ状態に合わせて第１筒状部４１及び電線部材２０の引き出し方向を容易に調整することができる。 When the movable part 42 is accommodated in the movable part 42 and the support shaft 43 is accommodated in the bearing hole 63, the movable part 42 is held in the accommodation space 62X so as to be rotatable about the support shaft 43 as the rotation axis. For example, the movable part 42 is held within the accommodation space 62X so as to be rotatable up and down in the figure with the support shaft 43 as a rotation axis. For example, the movable portion 42 is held by the holding member 60 so as to be movable in a direction intersecting the axial direction of the holding member 60 with the support shaft 43 as a rotation axis. Since the first cylindrical portion 41 is integrally formed with such a movable portion 42, the first cylindrical portion 41 is held by the holding member 60 so as to be movable relative to the holding member 60. For example, the first cylindrical portion 41 is held by the holding member 60 so as to be rotatable up and down in the figure with the support shaft 43 as the rotation axis. Thereby, the direction in which the first cylindrical portion 41 is pulled out to the outside of the holding member 60 can be easily varied. At this time, since the electric wire member 20 is housed inside the first cylindrical part 41, the electric wire member 20 is pulled out to the outside of the holding member 60 in accordance with the change in the drawing direction of the first cylindrical part 41. The direction can be easily adjusted. Therefore, even if the path of the wire harness 10 is bent sharply, as shown in FIG. 7, for example, the drawing direction of the first cylindrical portion 41 and the wire member 20 can be easily adjusted according to the bending state. can do.
　ここで、収容空間６２Ｘから引き出される第１筒状部４１の可動域は、例えば、保持部材６０と第１筒状部４１との接触により規制される。このとき、本実施形態の保持部材６０には、収容空間６２Ｘの開口端の一部を切り欠く拡大空間８０が設けられている。すなわち、拡大空間８０は、収容空間６２Ｘの開口幅を広げるように形成されている。この拡大空間８０は、第１筒状部４１が挿入可能な大きさに形成されている。このため、球状の可動部４２の回転と一緒に第１筒状部４１が可動する際に、拡大空間８０の内部に挿入されるように第１筒状部４１を可動させることができる。したがって、第１筒状部４１が拡大空間８０に挿入される分だけ、拡大空間８０が設けられている方向（図中上下方向）に対する第１筒状部４１の可動域を大きくすることができる。これにより、第１筒状部４１の内部に収容された電線部材２０の可動域を大きくすることができる。 Here, the range of motion of the first cylindrical part 41 pulled out from the accommodation space 62X is restricted by, for example, the contact between the holding member 60 and the first cylindrical part 41. At this time, the holding member 60 of this embodiment is provided with an enlarged space 80 that cuts out a part of the open end of the accommodation space 62X. That is, the enlarged space 80 is formed to widen the opening width of the accommodation space 62X. This expanded space 80 is formed in a size that allows the first cylindrical portion 41 to be inserted therein. Therefore, when the first cylindrical part 41 moves together with the rotation of the spherical movable part 42, the first cylindrical part 41 can be moved so as to be inserted into the expanded space 80. Therefore, the range of motion of the first cylindrical portion 41 in the direction in which the expanded space 80 is provided (the vertical direction in the figure) can be increased by the amount that the first cylindrical portion 41 is inserted into the expanded space 80. . Thereby, the range of motion of the electric wire member 20 housed inside the first cylindrical portion 41 can be increased.
　また、拡大空間８０の幅方向に沿う最大寸法が第１筒状部４１の幅方向に沿う最大寸法よりも大きく形成されるため、第１筒状部４１を拡大空間８０に好適に挿入することができる。これにより、第１筒状部４１が拡大空間８０に挿入される分だけ、第１筒状部４１の可動域を好適に拡大することができるとともに、可動部材４０の可動域を好適に拡大することができる。さらに、拡大空間８０の幅方向に沿う最大寸法が可動部４２の外形寸法よりも小さく形成されるため、可動部４２が拡大空間８０を通じて保持部６２の外部に抜けることを好適に抑制できる。 Further, since the maximum dimension along the width direction of the enlarged space 80 is formed larger than the maximum dimension along the width direction of the first cylindrical part 41, the first cylindrical part 41 can be suitably inserted into the enlarged space 80. Can be done. Thereby, the range of motion of the first cylindrical part 41 can be suitably expanded by the amount that the first cylindrical part 41 is inserted into the enlarged space 80, and the range of motion of the movable member 40 can also be suitably expanded. be able to. Furthermore, since the maximum dimension along the width direction of the enlarged space 80 is formed smaller than the external dimension of the movable part 42, it is possible to suitably suppress the movable part 42 from slipping out of the holding part 62 through the enlarged space 80.

For example, only one expansion space 80 may be provided in the holding portion 62. According to this configuration, the direction in which the range of motion of the first cylindrical portion 41 can be increased can be limited to one direction in which one expansion space 80 is provided.
　・図７～図９に示した変更例における拡大空間８０の平面形状は適宜変更することができる。例えば、拡大空間８０の角部８２をピン角に形成してもよい。例えば、拡大空間８０の長さ方向の寸法が短くなるように形成してもよい。例えば、各拡大空間８０の長さ方向の寸法を変更することにより、第１筒状部４１の可動域を容易に変更することができる。 - The planar shape of the enlarged space 80 in the modified examples shown in FIGS. 7 to 9 can be changed as appropriate. For example, the corner portion 82 of the enlarged space 80 may be formed into a pin angle. For example, the enlarged space 80 may be formed to have a shorter longitudinal dimension. For example, by changing the lengthwise dimension of each expansion space 80, the range of motion of the first cylindrical portion 41 can be easily changed.
　・図７～図９に示した変更例では、拡大空間８０を切り欠きに形成したが、これに限定されない。例えば、拡大空間８０は、収容空間６２Ｘに連通するとともに、第１筒状部４１が挿入可能に形成されていれば、保持部６２の周壁により囲まれた空間であってもよい。 - In the modified examples shown in FIGS. 7 to 9, the enlarged space 80 is formed as a cutout, but the invention is not limited to this.
