As in Patent Document 1, for example, the protector has a cylindrical shape in which the opening of the main body is covered with a lid, and an electric wire is arranged so as to penetrate between the main body and the lid.
　ところで、特許文献１では、電線の経路（延伸経路）が直線的な部分に装着されるプロテクタが示されているが、プロテクタは、電線の経路が湾曲する部分に装着される場合もある。この場合に、プロテクタは、電線の経路に沿うように湾曲して延びる湾曲部分を備えた構造とされる。そして、電線を曲げながらプロテクタの本体部に収容した後、本体部に蓋部を取り付けることによって、プロテクタを電線に装着する。 By the way, in Patent Document 1, a protector is shown in which the path (extension path) of the electric wire is attached to a linear portion, but the protector may be attached to a portion where the path of the electric wire is curved. In this case, the protector has a structure including a curved portion that is curved and extends along the path of the electric wire. Then, after the electric wire is bent and housed in the main body of the protector, the protector is attached to the electric wire by attaching the lid to the main body.

　ところが、電線の経路が湾曲する部分にプロテクタを装着する場合、プロテクタの本体部に電線を曲げながら収容しようとすると、曲げられた電線には曲げを解消しようとする弾性に基づいた復元力が作用する。その結果、電線が形状の復元に伴ってプロテクタの本体部から外れてしまう場合があり、電線に対するプロテクタの装着作業が難しかった。また、電線が形状の復元に伴ってプロテクタの本体部に強く押し付けられることにより、本体部が変形し、蓋部を本体部に正しく取り付けることが難しくなる場合もあった。 However, when a protector is attached to a portion where the path of the electric wire is curved, if the electric wire is to be accommodated in the main body of the protector while being bent, a restoring force based on elasticity that tries to eliminate the bending acts on the bent electric wire. do. As a result, the electric wire may come off from the main body of the protector as the shape is restored, and it is difficult to attach the protector to the electric wire. In addition, when the electric wire is strongly pressed against the main body of the protector as the shape is restored, the main body may be deformed and it may be difficult to correctly attach the lid to the main body.

＜本開示の実施形態の説明＞
　最初に、本開示の実施態様を列記して説明する。
　本開示のプロテクタは、
（１）開口部を有して電線を収容可能な本体部と、前記本体部の前記開口部を覆う蓋部とを備え、前記蓋部と前記本体部との間には、前記電線が貫通可能な配索空所を有し、前記本体部は１方向に湾曲しながら前記電線の長さ方向に延びる第１湾曲部を備え、前記第１湾曲部は、湾曲の外周側から前記配索空所へ突出する補強部を備えているプロテクタである。 <Explanation of Embodiments of the present disclosure>
First, embodiments of the present disclosure will be listed and described.
The protectors of this disclosure are
(1) A main body portion having an opening and capable of accommodating an electric wire and a lid portion covering the opening of the main body portion are provided, and the electric wire penetrates between the lid portion and the main body portion. The main body portion includes a first curved portion extending in the length direction of the electric wire while being curved in one direction, and the first curved portion is arranged from the outer peripheral side of the curvature. It is a protector equipped with a reinforcing part that protrudes into an empty space.
　本開示のプロテクタによれば、プロテクタの第１湾曲部における湾曲の外周側は、配索空所へ突出する補強部を備えており、変形剛性が補強部によって大きくされている。それゆえ、曲げられた電線が本体部に収容されて、電線が形状の復元に伴って第１湾曲部の湾曲の外周側において本体部に押し当てられたとしても、本体部の変形が抑制される。その結果、電線が本体部から抜け出し難く、且つ本体部の変形による蓋部と本体部の連結不良が生じ難いことから、プロテクタを湾曲した電線に対して容易に装着することができる。 According to the protector of the present disclosure, the outer peripheral side of the curve in the first curved portion of the protector is provided with a reinforcing portion that protrudes into the wiring space, and the deformation rigidity is increased by the reinforcing portion. Therefore, even if the bent electric wire is housed in the main body and the electric wire is pressed against the main body on the outer peripheral side of the curvature of the first curved portion as the shape is restored, the deformation of the main body is suppressed. NS. As a result, the electric wire is hard to come out from the main body, and the connection failure between the lid and the main body due to the deformation of the main body is hard to occur. Therefore, the protector can be easily attached to the curved electric wire.
　第１湾曲部に配された電線は、曲げられた状態から復元しようとすることによって、第１湾曲部において湾曲の内周側に偏って位置し、電線と第１湾曲部の湾曲の外周側との間には隙間が形成される。それゆえ、補強部が第１湾曲部の湾曲の外周側から配索空所へ突出するように設けられていても、補強部は配索空所において電線の邪魔になり難い。このように、補強部は、湾曲部分における電線の配索空所内での配置を考慮して設けられており、補強部が設けられることによるプロテクタの大型化が回避される。 The electric wire arranged in the first curved portion is biased toward the inner peripheral side of the curvature in the first curved portion by trying to restore from the bent state, and the electric wire and the outer peripheral side of the curvature of the first curved portion. A gap is formed between the and. Therefore, even if the reinforcing portion is provided so as to project from the outer peripheral side of the curve of the first curved portion to the wiring space, the reinforcing portion is unlikely to interfere with the electric wire in the wiring space. As described above, the reinforcing portion is provided in consideration of the arrangement of the electric wires in the wiring vacant space in the curved portion, and the increase in size of the protector due to the provision of the reinforcing portion is avoided.
　補強部が配索空所へ突出するように内向きに設けられることから、プロテクタの外表面から外向きに突出する場合に比して、プロテクタの外形に対する補強部の影響が低減されており、プロテクタの大型化を回避することができる。 Since the reinforcing portion is provided inward so as to project to the wiring space, the influence of the reinforcing portion on the outer shape of the protector is reduced as compared with the case where the reinforcing portion projects outward from the outer surface of the protector. It is possible to avoid increasing the size of the protector.
　補強部によってプロテクタの変形が抑えられることにより、電線の経路をプロテクタによって効果的に規制することができる。 By suppressing the deformation of the protector by the reinforcing part, the path of the electric wire can be effectively regulated by the protector.
（２）前記第１湾曲部は、湾曲の外周側から前記配索空所へ突出して厚さ寸法が大きくされた厚肉部を備え、前記補強部は前記厚肉部を有していることが好ましい。補強部が厚肉部を含むことにより、第１湾曲部における湾曲の外周側を任意の範囲において厚肉として補強することができる。例えば、広い範囲にわたって厚肉部を設けて、第１湾曲部における湾曲の外周側を広範囲において補強することも可能である。 (2) The first curved portion includes a thick-walled portion that protrudes from the outer peripheral side of the curve to the wiring space and has a large thickness dimension, and the reinforcing portion has the thick-walled portion. Is preferable. Since the reinforcing portion includes the thick portion, the outer peripheral side of the curvature in the first curved portion can be reinforced as a thick wall in an arbitrary range. For example, it is also possible to provide a thick portion over a wide range to reinforce the outer peripheral side of the curve in the first curved portion in a wide range.
（３）上記（２）において、前記厚肉部は前記配索空所へ突出する第１突条を有し、前記第１突条は前記電線を覆うコルゲートチューブの外周の谷部と係合可能とされていることが好ましい。第１突条によって第１湾曲部が湾曲の外周側において補強され、電線から及ぼされる力による本体部の変形が抑えられる。また、第１突条をコルゲートチューブの外周の谷部に差し入れて、第１突条とコルゲートチューブをコルゲートチューブの長さ方向において係合させることにより、プロテクタとコルゲートチューブを長さ方向において位置決めすることができる。 (3) In the above (2), the thick portion has a first ridge protruding into the wiring vacant space, and the first ridge engages with a valley portion on the outer periphery of a corrugated tube covering the electric wire. It is preferable that it is possible. The first ridge reinforces the first curved portion on the outer peripheral side of the curvature, and the deformation of the main body portion due to the force exerted from the electric wire is suppressed. Further, the protector and the corrugated tube are positioned in the length direction by inserting the first ridge into the valley of the outer periphery of the corrugated tube and engaging the first ridge and the corrugated tube in the length direction of the corrugated tube. be able to.
（４）前記本体部と前記蓋部を相互に連結する係合部を備えていることが好ましい。本体部と蓋部が係合部によって連結されることにより、バンドや粘着テープなどの別部材を用いることなく、プロテクタの電線に対する装着状態が維持される。また、本体部の変形が補強部によって防止されていることにより、本体部と蓋部の係合部が適切に位置決めされており、本体部と蓋部を係合部によって安定して連結することができる。 (4) It is preferable to have an engaging portion that connects the main body portion and the lid portion to each other. By connecting the main body and the lid by the engaging portion, the protector can be attached to the electric wire without using a separate member such as a band or an adhesive tape. Further, since the deformation of the main body is prevented by the reinforcing portion, the engaging portion between the main body and the lid is properly positioned, and the main body and the lid are stably connected by the engaging portion. Can be done.
（５）前記蓋部は、前記本体部の前記第１湾曲部において前記開口部を覆う第２湾曲部を備え、前記第２湾曲部は前記配索空所へ突出する第２突条を有し、前記第２突条は前記電線を覆うコルゲートチューブの外周の谷部と係合可能とされていることが好ましい。突条によって第２湾曲部が湾曲の外周側において補強され、蓋部の変形剛性の向上が図られる。また、第２突条をコルゲートチューブの外周の谷部に差し入れて、第２突条とコルゲートチューブをコルゲートチューブの長さ方向において係合させることにより、プロテクタとコルゲートチューブを長さ方向において位置決めすることができる。 (5) The lid portion includes a second curved portion that covers the opening in the first curved portion of the main body portion, and the second curved portion has a second ridge projecting to the wiring space. However, it is preferable that the second ridge can be engaged with the valley portion on the outer periphery of the corrugated tube covering the electric wire. The second curved portion is reinforced on the outer peripheral side of the curved portion by the ridge, and the deformation rigidity of the lid portion is improved. Further, the protector and the corrugated tube are positioned in the length direction by inserting the second ridge into the valley of the outer periphery of the corrugated tube and engaging the second ridge and the corrugated tube in the length direction of the corrugated tube. be able to.
　上記（５）は、好適には上記（２）と組み合わせて採用される。即ち、本体部に設けられた第１突条と、蓋部に設けられた第２突条とが、コルゲートチューブの外周の谷部にそれぞれ差し入れられて、コルゲートチューブに係合されることにより、プロテクタとコルゲートチューブをより強固に位置決めすることができる。 The above (5) is preferably adopted in combination with the above (2). That is, the first ridge provided on the main body and the second ridge provided on the lid are inserted into the valleys on the outer periphery of the corrugated tube and engaged with the corrugated tube. The protector and corrugated tube can be positioned more firmly.
（６）前記本体部の前記開口部は、少なくとも前記第１湾曲部の湾曲の外周側において前記電線の径方向の中央よりも前記蓋部側に位置していることが好ましい。曲げられた電線が弾性に基づく復元力によって本体部の壁面に押し当てられる際に、電線に作用する当接反力において電線を本体部の開口部側へ抜け出させる方向の分力が低減されることから、電線が本体部から開口部を通じて離脱し難い。 (6) It is preferable that the opening of the main body is located at least on the outer peripheral side of the curve of the first curved portion on the lid side of the center of the electric wire in the radial direction. When a bent wire is pressed against the wall surface of the main body by a restoring force based on elasticity, the component force in the direction of pulling the wire out to the opening side of the main body is reduced by the contact reaction force acting on the wire. Therefore, it is difficult for the electric wire to come off from the main body through the opening.

The protector 10 constitutes the wire harness 84 as shown in FIG. The wire harness 84 has a structure in which the protector 10 is attached to the electric wire 86 in an extrapolated state. Therefore, in the wire harness 84, the protector 10 extends in the length direction of the electric wire 86.
＜電線８６＞
　電線８６は、導電体の単線または撚り線によって構成された芯線の外側に、合成樹脂などの絶縁被覆を設けた絶縁電線とされている。なお、電線８６の芯線および絶縁被覆は、公知の一般的な材料によって形成される。好適には、電線８６は、曲げ剛性の高い単線の芯線を有する。なお、ワイヤハーネス８４を構成する電線８６は、１本であってもよいし、電線束を構成する複数本であってもよい。電線８６は、例えば、車両においてバッテリーとインバータやエアコンなどの機器とをつなぐ高電圧用の電線とされる。 <Electric wire 86>
The electric wire 86 is an insulated electric wire in which an insulating coating such as a synthetic resin is provided on the outside of a core wire composed of a single wire or a stranded wire of a conductor. The core wire and the insulating coating of the electric wire 86 are formed of a known general material. Preferably, the electric wire 86 has a single core wire having high bending rigidity. The number of electric wires 86 constituting the wire harness 84 may be one, or may be a plurality of electric wires constituting the bundle of electric wires. The electric wire 86 is, for example, an electric wire for high voltage that connects a battery and a device such as an inverter or an air conditioner in a vehicle.
＜コルゲートチューブ８８＞
　電線８６は、外装材としてのコルゲートチューブ８８に挿通されている。コルゲートチューブ８８は、合成樹脂によって形成されて、可撓性を有しており、電線８６の湾曲に追従する曲げ変形が許容される。コルゲートチューブ８８は、全体として円筒形状とされていると共に、周壁が蛇腹状の断面形状を有しており、径の小さい谷部９０が軸方向に所定の間隔で設けられている。 <Corrugated tube 88>
The electric wire 86 is inserted through a corrugated tube 88 as an exterior material. The corrugated tube 88 is made of synthetic resin and has flexibility, and bending deformation that follows the curvature of the electric wire 86 is allowed. The corrugated tube 88 has a cylindrical shape as a whole, a peripheral wall having a bellows-shaped cross-sectional shape, and valleys 90 having a small diameter provided at predetermined intervals in the axial direction.
　コルゲートチューブ８８が外挿された電線８６は、プロテクタ１０に挿通される。コルゲートチューブ８８は、図４に示すように、プロテクタ１０の本体部１４に対して開口部１６を通じて差し入れられて仮固定される。本体部１４に設けられた第１基端リブ４０と第１先端リブ２６は、コルゲートチューブ８８の谷部９０に差し入れられており、コルゲートチューブ８８の外周に向けて凹断面形状を有する谷部９０に対して、コルゲートチューブ８８の長さ方向において係止されている。これにより、コルゲートチューブ８８は、本体部１４に対して長さ方向に位置決めされている。コルゲートチューブ８８は、プロテクタ１０を貫通して両側に突出する長さを有しているが、例えば、プロテクタ１０よりも短いコルゲートチューブを長さ方向に複数設けることもできる。複数のコルゲートチューブを設ける場合、それらコルゲートチューブは、互いに同径であってもよいし、互いに異形であってもよい。 The electric wire 86 to which the corrugated tube 88 is extrapolated is inserted into the protector 10. As shown in FIG. 4, the corrugated tube 88 is inserted into the main body 14 of the protector 10 through the opening 16 and temporarily fixed. The first base end rib 40 and the first tip rib 26 provided in the main body portion 14 are inserted into the valley portion 90 of the corrugated tube 88, and the valley portion 90 having a concave cross-sectional shape toward the outer periphery of the corrugated tube 88. On the other hand, it is locked in the length direction of the corrugated tube 88. As a result, the corrugated tube 88 is positioned in the length direction with respect to the main body portion 14. The corrugated tube 88 has a length that penetrates the protector 10 and projects to both sides. For example, a plurality of corrugated tubes shorter than the protector 10 may be provided in the length direction. When a plurality of corrugated tubes are provided, the corrugated tubes may have the same diameter or different shapes from each other.
　コルゲートチューブ８８は、本体部１４の第１湾曲部２２に差し入れられた部分が、第１湾曲部２２に沿って１方向に湾曲している。コルゲートチューブ８８が湾曲することにより、湾曲の内周側ではコルゲートチューブ８８と本体部１４の第１内壁部３６との隙間が小さくされ、湾曲の外周側ではコルゲートチューブ８８と本体部１４の第１外壁部３０との隙間が大きくされている。また、コルゲートチューブ８８は、湾曲の内周側において長さ方向に収縮して谷部９０の幅が小さくなると共に、湾曲の外周側において長さ方向に伸長して谷部９０の幅が大きくなる。 In the corrugated tube 88, the portion inserted into the first curved portion 22 of the main body portion 14 is curved in one direction along the first curved portion 22. Since the corrugated tube 88 is curved, the gap between the corrugated tube 88 and the first inner wall portion 36 of the main body portion 14 is reduced on the inner peripheral side of the curvature, and the first of the corrugated tube 88 and the main body portion 14 on the outer peripheral side of the curvature. The gap with the outer wall portion 30 is increased. Further, the corrugated tube 88 contracts in the length direction on the inner peripheral side of the curve to reduce the width of the valley 90, and extends in the length direction on the outer peripheral side of the curve to increase the width of the valley 90. ..
　コルゲートチューブ８８の湾曲部分では、本体部１４の第１湾曲部２２において配索空所１２内へ突出する第１突条３２が、コルゲートチューブ８８の湾曲の外周に位置する谷部９０に差し入れられている。そして、第１突条３２は、コルゲートチューブ８８の外周の谷部９０に対して、コルゲートチューブ８８の長さ方向において係合可能とされている。これにより、コルゲートチューブ８８の湾曲部分は、本体部１４の第１湾曲部２２に対して、長さ方向において位置決めされている。 In the curved portion of the corrugated tube 88, the first ridge 32 protruding into the routing space 12 at the first curved portion 22 of the main body portion 14 is inserted into the valley portion 90 located on the outer periphery of the curvature of the corrugated tube 88. ing. The first ridge 32 can be engaged with the valley portion 90 on the outer periphery of the corrugated tube 88 in the length direction of the corrugated tube 88. As a result, the curved portion of the corrugated tube 88 is positioned in the length direction with respect to the first curved portion 22 of the main body portion 14.
　コルゲートチューブ８８によって覆われた電線８６は、図３，図４に破線で示すように、コルゲートチューブ８８への挿通部分において曲げられている。電線８６は、それ自体の弾性に基づく形状復元力によって、延伸経路において湾曲部分の曲率が小さくなるように延びている。即ち、電線８６の湾曲部分は、コルゲートチューブ８８内において、コルゲートチューブ８８の湾曲の内周側に接近した位置を延びる。また、電線８６における湾曲部分を長さ方向に外れた両側部分は、コルゲートチューブ８８内において、コルゲートチューブ８８の湾曲の外周側に接近した位置を延びる。電線８６は、弾性に基づく形状復元力によって、本体部１４の長さ方向の両端部分を湾曲の外周側へ押圧する。その結果、第１湾曲部２２には、第１外壁部３０に対して曲率を小さくする方向へ変形させようとする外力が作用する。ここにおいて、第１湾曲部２２の第１外壁部３０は、複数の第１突条３２が設けられており、曲げに対する変形剛性が大きくされている。それゆえ、電線８６の弾性力によって押圧される第１外壁部３０の変形が抑えられて、本体部１４の初期形状が維持される。 The electric wire 86 covered by the corrugated tube 88 is bent at the insertion portion into the corrugated tube 88 as shown by the broken line in FIGS. 3 and 4. The electric wire 86 extends so that the curvature of the curved portion becomes small in the stretching path due to the shape restoring force based on the elasticity of the electric wire 86 itself. That is, the curved portion of the electric wire 86 extends in the corrugated tube 88 at a position close to the inner peripheral side of the curve of the corrugated tube 88. Further, both side portions of the electric wire 86 that deviate from the curved portion in the length direction extend in the corrugated tube 88 at a position close to the outer peripheral side of the curved portion of the corrugated tube 88. The electric wire 86 presses both end portions of the main body portion 14 in the length direction toward the outer peripheral side of the curve by a shape restoring force based on elasticity. As a result, an external force that tends to deform the first curved portion 22 in the direction of reducing the curvature acts on the first outer wall portion 30. Here, the first outer wall portion 30 of the first curved portion 22 is provided with a plurality of first ridges 32, and the deformation rigidity with respect to bending is increased. Therefore, the deformation of the first outer wall portion 30 pressed by the elastic force of the electric wire 86 is suppressed, and the initial shape of the main body portion 14 is maintained.
　複数の第１突条３２が第１湾曲部２２の長さ方向に並んで設けられており、第１突条３２が第１湾曲部２２における第１外壁部３０に対して長さ方向の広い範囲に設けられている。それゆえ、第１突条３２による第１外壁部３０の補強効果が、より効果的に且つ広範囲に発揮される。 A plurality of first ridges 32 are provided side by side in the length direction of the first curved portion 22, and the first ridge 32 is wider in the length direction with respect to the first outer wall portion 30 in the first curved portion 22. It is provided in the range. Therefore, the reinforcing effect of the first outer wall portion 30 by the first ridge 32 is more effectively and widely exerted.
　また、第１湾曲部２２の第１外壁部３０が厚肉部３８を備えており、第１突条３２を外れた部位においても第１内壁部３６よりも厚肉とされていることにより、第１湾曲部２２の変形剛性がさらに大きくされている。 Further, the first outer wall portion 30 of the first curved portion 22 is provided with the thick portion 38, and the portion that is out of the first ridge 32 is also thicker than the first inner wall portion 36. The deformation rigidity of the first curved portion 22 is further increased.
　第１突条３２を含む厚肉部３８は、第１湾曲部２２の第１外壁部３０から配索空所１２へ向けて内面３４に突出して設けられている。それゆえ、厚肉部３８が第１外壁部３０から外面側に設けられている場合に比して、プロテクタ１０の外形に対する厚肉部３８の影響が抑えられて、プロテクタ１０の大型化が回避される。また、コルゲートチューブ８８が湾曲部分において配索空所１２内で湾曲の内周側に偏在することに着目して、厚肉部３８は第１湾曲部２２の湾曲の外周側である第１外壁部３０に設けられている。これにより、コルゲートチューブ８８とプロテクタ１０の第１湾曲部２２との間のスペースを効率よく利用して厚肉部３８が設けられている。また、第１突条３２は、湾曲することによって広がるコルゲートチューブ８８の外周側の谷部９０に差し入れられるように配置や高さが設定されている。これにより、コルゲートチューブ８８の外周側に形成されるスペースをうまく利用して、高さの大きな第１突条３２がプロテクタ１０の内面３４に突設されており、第１突条３２による優れた剛性補強効果が省スペースで実現されている。 The thick portion 38 including the first ridge 32 is provided so as to project from the first outer wall portion 30 of the first curved portion 22 toward the distribution space 12 on the inner surface 34. Therefore, as compared with the case where the thick portion 38 is provided on the outer surface side from the first outer wall portion 30, the influence of the thick portion 38 on the outer shape of the protector 10 is suppressed, and the size of the protector 10 is avoided. Will be done. Further, paying attention to the fact that the corrugated tube 88 is unevenly distributed on the inner peripheral side of the curve in the routing space 12 in the curved portion, the thick portion 38 is the first outer wall which is the outer peripheral side of the curve of the first curved portion 22. It is provided in the part 30. As a result, the thick portion 38 is provided by efficiently utilizing the space between the corrugated tube 88 and the first curved portion 22 of the protector 10. Further, the arrangement and height of the first ridge 32 are set so that the first ridge 32 can be inserted into the valley portion 90 on the outer peripheral side of the corrugated tube 88 that expands by bending. As a result, the first ridge 32 having a large height is projected on the inner surface 34 of the protector 10 by making good use of the space formed on the outer peripheral side of the corrugated tube 88, which is excellent due to the first ridge 32. The rigidity reinforcement effect is realized in a small space.
　電線８６とコルゲートチューブ８８が本体部１４にセットされた後、蓋部１８が本体部１４に上方から重ね合わされて、本体部１４と蓋部１８が係合部６６ａ，６６ｂによって連結される。これにより、電線８６とコルゲートチューブ８８が本体部１４と蓋部１８の間の配索空所１２に収容されて、図３に示すように、本体部１４と蓋部１８によって構成されたプロテクタ１０が、電線８６とコルゲートチューブ８８に対して外挿状態で装着される。本体部１４の変形が第１突条３２を含む厚肉部３８によって防止されていることにより、本体部１４のロック枠６８ａ，６８ｂと蓋部１８のロック片７０ａ，７０ｂとの位置ずれが回避されている。それゆえ、本体部１４と蓋部１８を係合部６６ａ，６６ｂによって容易に連結することができる。 After the electric wire 86 and the corrugated tube 88 are set on the main body 14, the lid 18 is superposed on the main body 14 from above, and the main body 14 and the lid 18 are connected by the engaging portions 66a and 66b. As a result, the electric wire 86 and the corrugated tube 88 are accommodated in the wiring space 12 between the main body portion 14 and the lid portion 18, and as shown in FIG. 3, the protector 10 composed of the main body portion 14 and the lid portion 18 is formed. Is attached to the electric wire 86 and the corrugated tube 88 in an extrapolated state. Since the deformation of the main body 14 is prevented by the thick portion 38 including the first ridge 32, the misalignment between the lock frames 68a and 68b of the main body 14 and the lock pieces 70a and 70b of the lid 18 is avoided. Has been done. Therefore, the main body portion 14 and the lid portion 18 can be easily connected by the engaging portions 66a and 66b.
　蓋部１８に設けられた第２基端リブ７６と第２先端リブ５２は、配索空所１２内へ突出しており、コルゲートチューブ８８の谷部９０に差し入れられる。第２基端リブ７６と第２先端リブ５２が、コルゲートチューブ８８の谷部９０に対して、コルゲートチューブ８８の長さ方向において係合可能とされることにより、コルゲートチューブ８８とプロテクタ１０が長さ方向において相互に位置決めされる。 The second base end rib 76 and the second tip rib 52 provided on the lid portion 18 project into the routing space 12 and are inserted into the valley portion 90 of the corrugated tube 88. The second base end rib 76 and the second tip rib 52 can be engaged with the valley portion 90 of the corrugated tube 88 in the length direction of the corrugated tube 88, so that the corrugated tube 88 and the protector 10 are longer. They are positioned relative to each other in the vertical direction.
　コルゲートチューブ８８の湾曲部分では、蓋部１８の第２湾曲部５０において配索空所１２へ突出した第２突条５８が、コルゲートチューブ８８の外周の谷部９０に差し入れられている。そして、第２突条５８は、コルゲートチューブ８８の外周の谷部９０に対して、コルゲートチューブ８８の長さ方向において係合可能とされている。これにより、コルゲートチューブ８８の湾曲部分は、長さ方向において、蓋部１８の第２湾曲部５０に対して位置決めされている。 In the curved portion of the corrugated tube 88, the second ridge 58 protruding into the wiring space 12 at the second curved portion 50 of the lid portion 18 is inserted into the valley portion 90 on the outer periphery of the corrugated tube 88. The second ridge 58 can be engaged with the valley portion 90 on the outer periphery of the corrugated tube 88 in the length direction of the corrugated tube 88. As a result, the curved portion of the corrugated tube 88 is positioned with respect to the second curved portion 50 of the lid portion 18 in the length direction.

The first curved portion 110 is provided with a first ridge 114. The first ridge 114 of the present embodiment extends not only to the first outer wall portion 30 but also to the first inner wall portion 36 as compared with the first ridge 32 of the first embodiment. In the first ridge 114, the circumferential end on the first outer wall portion 30 side reaches the circumferential end of the first curved portion 110, and the circumferential end on the first inner wall portion 36 side is the first curved portion. It does not reach the circumferential end of 110. In short, the first ridge 114 extends from the end of the first curved portion 110 on the side of the first outer wall portion 30 to the middle of the first inner wall portion 36 in the circumferential direction. A plurality of first ridges 114 are provided so as to be separated from each other in the length direction of the first curved portion 110, and the distance between the plurality of first ridges 114 is at the peripheral end portion on the first outer wall portion 30 side. It is narrower than the circumferential end on the first inner wall 36 side.
＜蓋部１０６＞
　蓋部１０６は、図６に示すように、略板状とされており、第２先端部１１６と第２湾曲部１１８が独立して設けられている。本実施形態の第２湾曲部１１８には、実施形態１の第２湾曲部５０のような第２突条５８は形成されていない。また、第２先端部１１６に第２先端リブ５２が設けられていると共に、第２湾曲部１１８の第２先端部１１６と反対側の端部には第２基端リブ７６が設けられている。第２先端部１１６は、先端側ヒンジ部１２０によって第１先端部１０８に対して開閉可能に連結されている。第２湾曲部１１８は、基端側ヒンジ部１２２によって第１湾曲部１１０に対して開閉可能に連結されている。また、第１湾曲部１１０の延伸方向に関する湾曲の外周側に取付部４４が設けられており、取付部４４によって第１湾曲部１１０の第１外壁部３０が補強されている。 <Cover 106>
As shown in FIG. 6, the lid portion 106 has a substantially plate shape, and the second tip portion 116 and the second curved portion 118 are provided independently. The second curved portion 118 of the present embodiment does not have a second ridge 58 like the second curved portion 50 of the first embodiment. Further, the second tip portion 116 is provided with the second tip rib 52, and the second base end rib 76 is provided at the end of the second curved portion 118 opposite to the second tip portion 116. .. The second tip portion 116 is openably and closably connected to the first tip portion 108 by the tip end side hinge portion 120. The second curved portion 118 is openably and closably connected to the first curved portion 110 by a hinge portion 122 on the proximal end side. Further, a mounting portion 44 is provided on the outer peripheral side of the curvature of the first curved portion 110 in the extending direction, and the first outer wall portion 30 of the first curved portion 110 is reinforced by the mounting portion 44.
　プロテクタ１００には、図５に示すように、コルゲートチューブ８８と電線８６が挿通される。プロテクタ１００にコルゲートチューブ８８と電線８６を配する際には、先ず、電線８６に外挿されたコルゲートチューブ８８がプロテクタ１００の本体部１０４の内周へ開口部１６を通じて差し入れられる。 As shown in FIG. 5, the corrugated tube 88 and the electric wire 86 are inserted into the protector 100. When arranging the corrugated tube 88 and the electric wire 86 on the protector 100, first, the corrugated tube 88 extrapolated to the electric wire 86 is inserted into the inner circumference of the main body portion 104 of the protector 100 through the opening 16.
　本体部１０４は、プロテクタ１００の周方向において半周よりも広い範囲を構成しており、本体部１０４の周方向端部に設けられた開口部１６が、電線８６の上下方向の中央に対して、より蓋部１０６側である上方に位置している。これにより、曲げられた電線８６が弾性的な形状復元力によって本体部１０４の第１外壁部３０に押し当てられたとしても、電線８６およびコルゲートチューブ８８に作用する当接反力が開口部１６側へ向けた分力を持ち難い。その結果、本体部１０４に差し入れられてセットされた電線８６およびコルゲートチューブ８８は、開口部１６を通じた本体部１０４からの抜けを生じ難い。 The main body 104 constitutes a wider range than half the circumference in the circumferential direction of the protector 100, and the opening 16 provided at the circumferential end of the main body 104 is relative to the center of the electric wire 86 in the vertical direction. It is located above the lid 106 side. As a result, even if the bent electric wire 86 is pressed against the first outer wall portion 30 of the main body portion 104 by the elastic shape restoration force, the contact reaction force acting on the electric wire 86 and the corrugated tube 88 is applied to the opening 16 It is difficult to have a component force toward the side. As a result, the electric wire 86 and the corrugated tube 88 inserted and set in the main body 104 are unlikely to come off from the main body 104 through the opening 16.
　また、本体部１０４の第１湾曲部１１０に第１突条１１４が設けられていることにより、第１湾曲部１１０の変形剛性が高められている。それゆえ、電線８６の形状復元力が本体部１０４に及ぼされる際に、第１湾曲部１１０の変形が防止される。本実施形態の第１突条１１４は、実施形態１の第１突条３２に比べて周方向により長く設けられている。それゆえ、第１湾曲部１１０の変形剛性が第１突条１１４によってより効果的に補強されている。また、コルゲートチューブ８８の谷部９０に差し入れられた第１突条１１４が、コルゲートチューブ８８の谷部９０と長さ方向において係合可能とされることによって、コルゲートチューブ８８が本体部１０４に対して長さ方向でより確実に位置決めされる。 Further, since the first ridge 114 is provided on the first curved portion 110 of the main body portion 104, the deformation rigidity of the first curved portion 110 is enhanced. Therefore, when the shape restoring force of the electric wire 86 is applied to the main body portion 104, the deformation of the first curved portion 110 is prevented. The first ridge 114 of the present embodiment is provided longer in the circumferential direction than the first ridge 32 of the first embodiment. Therefore, the deformation rigidity of the first curved portion 110 is more effectively reinforced by the first ridge 114. Further, the first ridge 114 inserted into the valley portion 90 of the corrugated tube 88 can be engaged with the valley portion 90 of the corrugated tube 88 in the length direction, so that the corrugated tube 88 can be engaged with the main body portion 104. It is more reliably positioned in the length direction.
　さらに、本体部１０４がより深い溝形状とされることにより、本体部１０４の変形剛性が断面形状によっても大きくされている。それゆえ、電線８６の押し当てによる本体部１０４の変形が効果的に防止される。特に本実施形態では、蓋部１０６が略板状とされており、本体部１０４の深さが大きく確保されていることから、本体部１０４において断面形状による高い変形剛性が実現されている。 Further, since the main body portion 104 has a deeper groove shape, the deformation rigidity of the main body portion 104 is also increased depending on the cross-sectional shape. Therefore, the deformation of the main body 104 due to the pressing of the electric wire 86 is effectively prevented. In particular, in the present embodiment, the lid portion 106 has a substantially plate shape, and the main body portion 104 has a large depth, so that the main body portion 104 is realized to have high deformation rigidity due to its cross-sectional shape.
　電線８６およびコルゲートチューブ８８が本体部１０４にセットされた状態で本体部１０４の変形が抑制されることにより、本体部１０４のロック枠６８ａ，６８ｂと蓋部１０６のロック片７０ａ，７０ｂとの位置ずれが防止される。それゆえ、本体部１０４の開口部１６を蓋部１０６によって閉じる際に、本体部１０４と蓋部１０６の係合部６６ａ，６６ｂによる連結が容易になり、プロテクタ１００の電線８６およびコルゲートチューブ８８への装着作業が簡単になる。 The positions of the lock frames 68a and 68b of the main body 104 and the lock pieces 70a and 70b of the lid 106 are suppressed by suppressing the deformation of the main body 104 with the electric wire 86 and the corrugated tube 88 set in the main body 104. Misalignment is prevented. Therefore, when the opening 16 of the main body 104 is closed by the lid 106, the main body 104 and the lid 106 can be easily connected by the engaging portions 66a and 66b, and the protector 100 is connected to the electric wire 86 and the corrugated tube 88. Installation work is easy.
　なお、本実施形態では、第１湾曲部１１０の湾曲に関して外周側に位置する側壁部１１２ａを含む本体部１０４の外側の側壁だけでなく、内周側に位置する側壁部１１２ｂを含む本体部１０４の内側の側壁も、上下方向の高さ寸法が大きくされている。これにより、本体部１０４の開口部１６は、第１湾曲部１１０の湾曲に関する外周側だけでなく内周側においても、電線８６の軸直角方向の中央よりも蓋部１０６側に位置している。しかしながら、電線８６が弾性によって押し当てられるのは主に本体部１０４の外側の側壁であることから、本体部１０４の外側においてのみ側壁を高くして開口部１６を蓋部１０６側に偏在させることによっても、電線８６を本体部１０４から抜け難くすることができる。もっとも、第１湾曲部１１０において電線８６が本体部１０４の内側の側壁（側壁部１１２ｂ）に押し当てられる場合等には、本体部１０４の内側の側壁を少なくとも第１湾曲部１１０において高くすることが好ましい。また、本体部１０４の側壁の高さを電線８６が押し当てられる部分において長さ方向で部分的に高くすることによっても、電線８６の抜けを防ぐ効果を得ることができる。このように、開口部１６を電線８６の中心よりも蓋部１０６側に位置させる場合、必ずしも開口部１６の全体が電線８６の中心よりも蓋部１０６側に位置している必要はなく、開口部１６の少なくとも一部が電線８６の中心よりも蓋部１０６側に位置していればよい。 In the present embodiment, not only the outer side wall of the main body 104 including the side wall 112a located on the outer peripheral side with respect to the curvature of the first curved portion 110, but also the main body 104 including the side wall 112b located on the inner peripheral side. The inner side wall of the is also increased in height in the vertical direction. As a result, the opening 16 of the main body 104 is located on the lid 106 side of the center of the electric wire 86 in the direction perpendicular to the axis, not only on the outer peripheral side but also on the inner peripheral side regarding the curvature of the first bending portion 110. .. However, since it is mainly the outer side wall of the main body 104 that the electric wire 86 is elastically pressed, the side wall is raised only on the outside of the main body 104 so that the openings 16 are unevenly distributed on the lid 106 side. Also, the electric wire 86 can be made difficult to be pulled out from the main body portion 104. However, when the electric wire 86 is pressed against the inner side wall (side wall portion 112b) of the main body portion 104 in the first curved portion 110, the inner side wall of the main body portion 104 should be raised at least in the first curved portion 110. Is preferable. Further, by partially increasing the height of the side wall of the main body 104 in the length direction at the portion where the electric wire 86 is pressed, the effect of preventing the electric wire 86 from coming off can be obtained. In this way, when the opening 16 is positioned closer to the lid 106 than the center of the electric wire 86, the entire opening 16 does not necessarily have to be located closer to the lid 106 than the center of the electric wire 86. At least a part of the portion 16 may be located on the lid portion 106 side of the center of the electric wire 86.

　連結部１３８は、直線的に延びる円筒状の部材であって、例えば、半円筒形状の２つの分割部材を組み合わせて固定することにより構成されている。この場合、２つの分割部材の分割方向は特に限定されず、第１部分１３４の本体部１０４と蓋部１８の分割方向と同じであっても良いし、異なっていてもよい。連結部１３８は、第１部分１３４と第２部分１３６の少なくとも一方と一体形成されていてもよいが、第１部分１３４と第２部分１３６とは別体とされていてもよい。本実施形態では、図９に示すように、連結部１３８の下半部分が第１部分１３４の下半部分と第２部分１３６の下半部分に対して一体的に連続して設けられている。そして、第１部分１３４の下半部分と連結部１３８の下半部分と第２部分１３６の下半部分とによって、プロテクタ１３０の本体部１３９が構成されている。なお、連結部１３８の上半部分は、連結部１３８の下半部分に対して、例えばヒンジ部によって開閉可能につながっていてもよいし、独立した別部品とされていてもよい。 The connecting portion 138 is a cylindrical member that extends linearly, and is configured by, for example, combining and fixing two semi-cylindrical divided members. In this case, the dividing direction of the two dividing members is not particularly limited, and may be the same as or different from the dividing direction of the main body portion 104 and the lid portion 18 of the first portion 134. The connecting portion 138 may be integrally formed with at least one of the first portion 134 and the second portion 136, but the first portion 134 and the second portion 136 may be separate bodies. In the present embodiment, as shown in FIG. 9, the lower half portion of the connecting portion 138 is integrally and continuously provided with respect to the lower half portion of the first portion 134 and the lower half portion of the second portion 136. .. Then, the lower half portion of the first portion 134, the lower half portion of the connecting portion 138, and the lower half portion of the second portion 136 constitute the main body portion 139 of the protector 130. The upper half portion of the connecting portion 138 may be connected to the lower half portion of the connecting portion 138 so as to be openable and closable by, for example, a hinge portion, or may be an independent separate part.
　本実施形態において示すように、プロテクタ１３０の本体部１３９は、複数の第１湾曲部２２を備えていてもよい。この場合に、複数の第１湾曲部２２は、それぞれが１方向に湾曲していれば、湾曲方向は互いに異なっていてもよい。本実施形態では、第１基端部２４，２４と連結部１３８の下半部分とによって構成される直線的に延びる部分が、第１湾曲部２２，２２の間に設けられているが、複数の第１湾曲部２２が直線的に連続して隣接配置されていてもよい。 As shown in this embodiment, the main body portion 139 of the protector 130 may include a plurality of first curved portions 22. In this case, as long as each of the plurality of first curved portions 22 is curved in one direction, the bending directions may be different from each other. In the present embodiment, a linearly extending portion composed of the first base end portions 24, 24 and the lower half portion of the connecting portion 138 is provided between the first curved portions 22, 22. The first curved portion 22 of the above may be arranged adjacent to each other in a straight line.
＜実施形態４＞
　図１０には、別の具体例である実施形態４を示す。実施形態４のプロテクタ１４０は、第１湾曲部２２の第１外壁部３０が実施形態１のような第１突条を備えておらず、第１外壁部３０に補強部としての厚肉部１４２が設けられた構造とされている。厚肉部１４２は、第１外壁部３０の一部が内面３４において本体部１４の内周側へ向けて部分的に突出することによって形成されている。第１外壁部３０は、厚肉部１４２が設けられた部分において、本体部１４の内周へ向けて部分的に厚肉とされている。 <Embodiment 4>
FIG. 10 shows another specific example, the fourth embodiment. In the protector 140 of the fourth embodiment, the first outer wall portion 30 of the first curved portion 22 does not have the first ridge as in the first embodiment, and the first outer wall portion 30 has a thick portion 142 as a reinforcing portion. It is said that the structure is provided with. The thick portion 142 is formed by partially projecting a part of the first outer wall portion 30 toward the inner peripheral side of the main body portion 14 on the inner surface 34. The first outer wall portion 30 is partially thickened toward the inner circumference of the main body portion 14 in the portion where the thick portion 142 is provided.
　第１湾曲部２２の第１外壁部３０に厚肉部１４２が設けられていることにより、第１外壁部３０の変形剛性が高められている。また、厚肉部１４２は、実施形態１の第１突条３２に比して、長さ方向においてより大きな寸法で連続して設けられていることから、厚肉部１４２の変形剛性をより効果的に大きくすることができ、且つ応力の分散化も図られ得る。 By providing the thick portion 142 on the first outer wall portion 30 of the first curved portion 22, the deformation rigidity of the first outer wall portion 30 is enhanced. Further, since the thick portion 142 is continuously provided with a larger dimension in the length direction as compared with the first ridge 32 of the first embodiment, the deformation rigidity of the thick portion 142 is more effective. The stress can be increased and the stress can be dispersed.
