（発明が解決しようとする課題）
上記した特許文献１に記載されている車両用ドアロック装置においては、インナーワイヤの端部に固着された連結具が円柱状に形成されていて中間部外周にてインナーワイヤの端部に固着されており、回転レバーの先端部には折り返し部が形成されていて、この折り返し部に円柱状の連結具を組付けるためのスリット（インナーワイヤを挿通するためのもの）と連結孔（連結具の端部が固定される部位）が形成されている。このため、回転レバーの形状が簡素化できないものの、円柱状の連結具が連結孔に嵌合するように構成すれば、連結具と連結孔（回転レバー）との連結部でのガタツキ（連結孔の径方向でのガタツキ）を無くすことが可能である。 (Problems to be solved by the invention)
In the vehicle door lock device described in Patent Document 1 described above, the coupling member fixed to the end portion of the inner wire is formed in a columnar shape, and is fixed to the end portion of the inner wire at the outer periphery of the intermediate portion. The rotary lever has a folded portion at the tip, and a slit (for inserting the inner wire) and a coupling hole (for coupling the coupling tool) for assembling the cylindrical coupling tool to the folded portion. The site | part to which an edge part is fixed is formed. For this reason, although the shape of the rotating lever cannot be simplified, if the cylindrical connecting tool is configured to fit into the connecting hole, rattling (the connecting hole) at the connecting portion between the connecting tool and the connecting hole (rotating lever). Can be eliminated.

一方、上記した特許文献２に記載されているロッドと回転レバーの結合構造では、回転レバーに折り返し部を設ける必要がないものの、回転レバーの板厚方向（連結孔の軸方向）にてロッドが移動しないようにするためのループ状弾性舌片が回転レバーに設けられていて、回転レバーの形状が簡素化できない。また、この結合構造では、ロッドの先端部がクランク状に形成されるとともに、連結孔が回転レバーの平板部位の形成されているため、連結孔に挿通されるロッドの先端部（クランク状に形成されている部位の中間部）と連結孔の内壁間に所望の隙間が必要であり、ロッドと連結孔（回転レバー）との連結部でのガタツキ（連結孔の径方向でのガタツキ）を無くすことはできない。   On the other hand, in the joint structure of the rod and the rotary lever described in Patent Document 2 described above, although it is not necessary to provide a turn-up portion on the rotary lever, the rod does not move in the plate thickness direction of the rotary lever (the axial direction of the connecting hole). A loop-like elastic tongue for preventing movement is provided on the rotary lever, and the shape of the rotary lever cannot be simplified. Further, in this coupling structure, the tip of the rod is formed in a crank shape, and the connecting hole is formed as a flat plate portion of the rotary lever, so the tip of the rod inserted into the connecting hole (formed in the shape of a crank) A desired gap is required between the intermediate part of the part being connected) and the inner wall of the connecting hole, eliminating backlash at the connecting part between the rod and the connecting hole (rotating lever) (backlash in the radial direction of the connecting hole). It is not possible.

It is possible to eliminate the backlash (the backlash in the radial direction of the connecting hole 23b (left and right direction in FIG. 4) and the backlash in the axial direction of the connecting hole 23b (up and down direction in FIG. 4)). It is possible to prevent abnormal noise generation and malfunction of the operation cable 24. Moreover, in this embodiment, since the operation cable 24 having the outer tube 24a and the inner wire 24b is employed, the degree of freedom in routing is large, and the operation cable 24 can be easily arranged.

また、この実施形態では、連結具２４ｄの第２屈曲部２４ｘ２が、その連結孔２３ｂの一側内壁２３ｂ１側に位置する部位に、上記した曲面２４ｙを有しているため、連結孔２３ｂに対して連結具２４ｄの先端部２４ｄ１を組付ける際の組付け性が向上する。また、この実施形態では、連結具２４ｄの基端部に回り止め用の突起２４ｄ２が設けられるとともに、ケーブルキャップ２４ｃの先端部に突起２４ｄ２が嵌合可能な凹部２４ｃ１が設けられている。このため、連結具２４ｄの連結孔（回転レバー）２３ｂへの組付に際して、回り止め用の突起２４ｄ２を凹部２４ｃ１に嵌合することで、アウターチューブ２４ａとインナーワイヤ２４ｂの相対回転を規制できて、連結具２４ｄの連結孔（回転レバー）２３ｂへの組付性を向上させることが可能である。なお、連結具２４ｄの連結孔（回転レバー）２３ｂへの組付は、図５の（ａ）の状態から（ｂ）の状態を経て（ｃ）の状態とすることにより行われている。   Further, in this embodiment, the second bent portion 24x2 of the connector 24d has the curved surface 24y at the portion located on the one side inner wall 23b1 side of the connection hole 23b. Thus, the assembling property when assembling the distal end portion 24d1 of the connector 24d is improved. In this embodiment, a rotation-preventing protrusion 24d2 is provided at the base end of the connector 24d, and a recess 24c1 into which the protrusion 24d2 can be fitted is provided at the distal end of the cable cap 24c. For this reason, when the coupling tool 24d is assembled to the coupling hole (rotating lever) 23b, the rotation of the outer tube 24a and the inner wire 24b can be restricted by fitting the rotation preventing projection 24d2 into the recess 24c1. It is possible to improve the assembling property of the connecting tool 24d to the connecting hole (rotating lever) 23b. In addition, the assembly | attachment to the connection hole (rotary lever) 23b of the connection tool 24d is performed by making the state of (c) through the state of (b) from the state of (a) of FIG.

上記実施形態においては、連結具２４ｄの基端部に回り止め用の突起（係合部）２４ｄ２が設けられるとともに、ケーブルキャップ２４ｃの先端部内周に前記突起（係合部）２４ｄ２が嵌合可能な凹部（係止部）２４ｃ１が設けられているが、連結具（２４ｄ）の基端部に回り止め用の凹部（係合部）が設けられるとともに、ケーブルキャップ（２４ｃ）の先端部に前記凹部（係合部）が嵌合可能な突起（係止部）が設けられるようにして実施することも可能である。   In the above-described embodiment, a rotation-preventing projection (engagement portion) 24d2 is provided at the base end portion of the connector 24d, and the projection (engagement portion) 24d2 can be fitted to the inner periphery of the distal end portion of the cable cap 24c. The concave portion (locking portion) 24c1 is provided, but a locking recess portion (engaging portion) is provided at the base end portion of the coupling tool (24d), and the cable cap (24c) is provided at the distal end portion thereof.
