Further, the locking projection 29 is formed with a locking surface 32 that is hooked on the locking portion 27 of the main body side locking portion 15 when a force is applied in the pulling direction after passing through the bridge portion 26 of the main body side locking portion 15. To. The locking surface 32 is formed on a surface parallel to the locking portion 27 (one side portion of the bridge portion 26).

ロック部２４は、嵌め合いにより図４に示す如くの嵌合状態に形成される。図示の嵌合状態において、本体側ロック部１５とカバー側ロック部２０との間には、幾つかの嵌合ガタ（嵌合クリアランスや結合クリアランスなどと言われる嵌合構造上、必要となるクリアランス）が生じる。具体的には、本体側ロック部１５における一対の橋脚部２５と、カバー側ロック部２０におけるアーム部２８の両側部との間に嵌合ガタＧ１、Ｇ２が生じる。また、本体側ロック部１５の係止部２７とアーム部２８の係止面３２との間に嵌合ガタＧ３が生じる。 The lock portion 24 is formed in a fitted state as shown in FIG. 4 by fitting. In the fitted state shown in the figure, there is some fitting play (a clearance required for the fitting structure called fitting clearance, coupling clearance, etc.) between the main body side lock portion 15 and the cover side lock portion 20. ) Occurs. Specifically, fitting backlashes G1 and G2 occur between the pair of bridge piers 25 in the main body side lock portion 15 and both side portions of the arm portions 28 in the cover side lock portion 20. Further, a fitting backlash G3 is generated between the locking portion 27 of the main body side locking portion 15 and the locking surface 32 of the arm portion 28.

ロック部２４の嵌合状態に関し、例えば嵌合ガタＧ１が図示の間隔よりも狭くなり、その狭くなった分だけ嵌合ガタＧ２の図示間隔が広くなるような場合、プロテクタ本体５とプロテクタカバー６は矢印Ｘ１で示す方向に位置ズレする。また、逆に嵌合ガタＧ２が図示の間隔よりも狭くなり、その狭くなった分だけ嵌合ガタＧ１の図示間隔が広くなるような場合には、プロテクタ本体５とプロテクタカバー６は矢印Ｘ２で示す方向に位置ズレする。すなわち、プロテクタ本体５とプロテクタカバー６との間で小さな変形が起こる。さらに、嵌合ガタＧ３が図示の間隔の状態であれば、プロテクタ本体５に対しプロテクタカバー６が完全に閉じていると言えるが、アーム部２８の係止面３２が本体側ロック部１５の係止部２７に引っ掛かる（当接する）状態であれば、嵌合ガタＧ３はゼロになり、その分、プロテクタカバー６がプロテクタ本体５に対し矢印Ｙで示す方向に位置ズレする。すなわち、プロテクタ本体５とプロテクタカバー６との間に嵌合ガタＧ４が生じ、プロテクタカバー６が浮き上がってしまうような若干開いた状態になる。プロテクタカバー６が浮き上がり、矢印Ｙで示す方向に位置ズレが生じれば、これがワイヤハーネス１（図１参照）における経路のバラツキの一種となって、プロテクタ４周辺に配設された他の部品等にプロテクタカバー６が干渉してしまうという虞がある（走行時の振動等が加わると干渉してしまう虞がある）。尚、本実施例においては、便宜上、他の部品等に干渉してしまうような図にはしていないものとする。 Regarding the fitting state of the lock portion 24, for example, when the fitting backlash G1 is narrower than the illustrated interval and the indicated spacing of the fitting backlash G2 is widened by the narrowing, the protector body 5 and the protector cover 6 Is displaced in the direction indicated by the arrow X1. On the contrary, when the fitting backlash G2 is narrower than the shown interval and the shown spacing of the fitting backlash G1 is widened by the narrowing, the protector body 5 and the protector cover 6 are indicated by arrows X2. The position shifts in the indicated direction. That is, a small deformation occurs between the protector main body 5 and the protector cover 6. Further, if the fitting backlash G3 is in the state of the interval shown in the drawing, it can be said that the protector cover 6 is completely closed to the protector main body 5, but the locking surface 32 of the arm portion 28 is engaged with the main body side lock portion 15. If it is caught (contacted) with the stop portion 27, the fitting backlash G3 becomes zero, and the protector cover 6 is displaced with respect to the protector main body 5 in the direction indicated by the arrow Y. That is, a fitting backlash G4 is generated between the protector main body 5 and the protector cover 6, and the protector cover 6 is in a slightly opened state so as to be lifted. If the protector cover 6 is lifted and the position is displaced in the direction indicated by the arrow Y, this becomes a kind of path variation in the wire harness 1 (see FIG. 1), and other parts and the like arranged around the protector 4 and the like. There is a risk that the protector cover 6 will interfere with the cover (there is a risk of interference if vibration or the like during traveling is applied). In this embodiment, for the sake of convenience, it is assumed that the figure does not interfere with other parts or the like.

＜巻き付け固定部３３について＞
図１及び図５において、ロック部２４の嵌合状態に関しては、上記の如く位置ズレが生じてしまう虞がある。そのためプロテクタ４には、巻き付け固定部３３がロック部２４の位置に合わせて複数箇所設けられる。巻き付け固定部３３は、ロック部２４の上から上記配索経路に合わせてのびるプロテクタ軸の軸回りに巻き付けてプロテクタ本体５及びプロテクタカバー６を固定状態にするためのものとして設けられる。本実施例の巻き付け固定部３３は５箇所設けられる。尚、図２及び図３においては、矢印Ｐが指し示す５つの位置のロック部２４が配設対象になる。巻き付け固定部３３は、上記位置ズレが生じる虞のある箇所（若しくはその箇所に近い）のロック部２４に設けられる。巻き付け固定部３３としては、テープ又はバンドが採用される。尚、巻き付け固定部３３は、テープ又はバンドでなくても上記位置ズレを防止し固定状態にすることができれば、特に限定されないものとする。テープは、アセテート製のクロスにアクリル系やゴム系の粘着材を塗布したものが一例として挙げられるものとする。テープは、この長手方向に伸びの生じないものが好ましいものとする。また、ロック部２４よりも幅広のテープが好ましいものとする。本実施例で採用されるテープは、絶縁性を有する。巻き付け固定部３３は、テープを２〜３周、強く巻き付けることにより形成される（巻き付けの回数は一例であるものとする。但し、テープを緩く巻き付けてしまうのはいけないものとする）。巻き付け固定部３３は、一つのロック部２４のみや、二つのロック部２４に跨るような状態に設けられる。巻き付け固定部３３は、上記胴部８のみならず上記首部９のロック部２４に対しても設けられる。 <About the winding fixing part 33>
In FIGS. 1 and 5, with respect to the fitted state of the lock portion 24, there is a possibility that the position shift may occur as described above. Therefore, the protector 4 is provided with a plurality of winding fixing portions 33 in accordance with the positions of the lock portions 24. The winding fixing portion 33 is provided for winding the protector main body 5 and the protector cover 6 in a fixed state by winding around the axis of the protector shaft extending from above the lock portion 24 in accordance with the wiring path. The winding fixing portion 33 of this embodiment is provided at five places. In addition, in FIGS. 2 and 3, the lock portion 24 at the five positions indicated by the arrow P is the object of arrangement. The winding fixing portion 33 is provided at a lock portion 24 at a location (or near that location) where the above-mentioned positional deviation may occur. A tape or a band is adopted as the winding fixing portion 33. The winding fixing portion 33 is not particularly limited as long as it can prevent the above-mentioned misalignment and put it in a fixed state even if it is not a tape or a band. An example of the tape is a cloth made of acetate coated with an acrylic or rubber adhesive. It is preferable that the tape does not stretch in the longitudinal direction. Further, it is preferable that the tape is wider than the lock portion 24. The tape used in this embodiment has insulating properties. The wrapping fixing portion 33 is formed by wrapping the tape tightly for 2 to 3 turns (the number of wrappings is an example, but the tape must not be wrapped loosely). The winding fixing portion 33 is provided so as to straddle only one lock portion 24 or two lock portions 24. The winding fixing portion 33 is provided not only on the body portion 8 but also on the lock portion 24 of the neck portion 9.

＜プロテクタ４及びワイヤハーネス１の効果について＞
