The wire harness 3 fixed to the harness fixing portion 16 is further extended and connected to a power source mounted on the vehicle body.
For example, as shown in FIG. 4, when the length required for routing between the wire harness 3 and the vehicle body side is set when the slide door 1 is closed, an extra length is generated when the slide door 1 is half-opened and hangs down. become. The power feeding device 2 is provided with a first arm 6 and a second arm 7 that are pivotably movable on the slide door 1. The wire harness 3 is held by the harness holding portion 12 of the second arm 7, and the torsion coil spring 9 is used.

In the power feeding device 2, the sliding door 1 is provided with regulating means 17 that regulates the amount of movement of the second arm 7 when the sliding door 1 is opened and closed. The restricting means 17 includes a fixed portion 18 that is fixed to the slide door 1 and a curved-shaped restricting portion 19 that restricts the amount of movement of the second arm 7.
In addition, the power feeding device 2 is provided with a protrusion 20 at the tip of the second arm 7 that contacts the regulating means 17. The projecting portion 20 extends from the distal end of the second arm 7 along the outer periphery of the second arm 7, and has a substantially semi-cylindrical extension portion 21, and rises from the outer periphery of the extension portion 21 to the restricting portion 19 of the restricting means 17. The contact part 22 which contacts is provided. The contact portion 22 is formed in a wall shape that rises at an angle so that the height gradually increases from the outer peripheral surface toward the second arm 7 side at the rear end of the extension portion 21 toward the second arm 7 side. The protrusion 20 moves the second arm 7 in a direction gradually separating from the restricting means 17 by moving the contact portion 22 that gradually increases while contacting the restricting portion 19 of the restricting means 17.
Thus, when the sliding device 1 is opened and closed, the power feeding device 2 uses the protrusion 20 that contacts the regulating means 17 to regulate the movement amount of the second arm 7 when the regulating means 17 regulates the movement amount of the second arm 7. A function of avoiding direct contact with the portion 17 is provided.

次に作用を説明する。
スライドドア1の給電装置2は、図4に示すように、スライドドア1の閉鎖状態において、ワイヤハーネス3が車体側のハーネス固定部16を支点に後方に引かれることから、捩りコイルばね9の付勢力に抗して第1アーム6が反時計方向(反余長吸収方向)に回転され、第2アーム7が下方に位置されて先端側を後方に向けるように回転する。
これにより、給電装置2は、第2アーム7のハーネス保持部12と車体側のハーネス固定部16との間で、捩りコイルばね9の付勢力によってワイヤハーネス3を適度に緊張した余長の無い状態に保持する。
給電装置2は、スライドドア1の閉鎖状態から開放状態への移行状態において、第2アーム7のハーネス保持部12が車体側のハーネス固定部16に近づくことで、ワイヤハーネス3の余長分が垂れ下がろうとする。給電装置2は、捩りコイルばね9の付勢力で第1アーム6が時計方向(余長吸収方向)に回転され、第2アーム7が上方に持ち上げられて先端側を下方に向けるように回転する。上方に持ち上げられる第2アーム7は、突起部20の接触部22が規制手段17の規制部19に接触し、移動を規制される。
これにより、給電装置2は、第2アーム7のハーネス保持部12から車体側のハーネス固定部15に向かって延びるワイヤハーネス3を上方に引き上げ、ワイヤハーネス3の余長の垂れ下がりを防止する。また、給電装置2は、規制手段17に接触する突起部20によって、第2アーム7が規制手段17へ直接的に接触することを回避する。(図1参照)
給電装置2は、スライドドア1の開放状態において、ワイヤハーネス3が車体側のハーネス固定部16を支点に前方に引かれることから、捩りコイルばね9の付勢力に抗して第1アーム6が反時計方向(反余長吸収方向)にわずかに回転され、第2アーム7が下方にわずかに引き下げられて先端側を斜め後方に向けるように回転する。このとき、下方に引き下げられる第2アーム7は、突起部20の接触部22が規制手段17の規制部19に接触し、移動を規制されている。
これにより、給電装置2は、第2アーム7のハーネス保持部12と車体側のハーネス固定部16との間で、捩りコイルばね9の付勢力によってワイヤハーネス3を持ち上げて適度に緊張した状態に保持し、ワイヤハーネス3の余長を吸収する。(図2参照)
Next, the operation will be described.
As shown in FIG. 4, the power feeding device 2 of the sliding door 1 is configured such that the wire harness 3 is pulled backward with the harness fixing portion 16 on the vehicle body side as a fulcrum in the closed state of the sliding door 1. The first arm 6 is rotated counterclockwise (anti-extra length absorption direction) against the urging force, and the second arm 7 is positioned below and rotated so that the tip side is directed rearward.
Thereby, the electric power feeder 2 does not have the length which moderately tensioned the wire harness 3 with the urging | biasing force of the torsion coil spring 9 between the harness holding | maintenance part 12 of the 2nd arm 7, and the harness fixing | fixed part 16 by the side of a vehicle body. Keep in state.
In the state where the sliding door 1 is transitioned from the closed state to the open state, the power feeding device 2 has the extra length of the wire harness 3 as the harness holding portion 12 of the second arm 7 approaches the harness fixing portion 16 on the vehicle body side. Try to hang down. The power feeding device 2 rotates so that the first arm 6 is rotated clockwise (the surplus length absorption direction) by the urging force of the torsion coil spring 9, and the second arm 7 is lifted upward and the front end side is directed downward. . The movement of the second arm 7 lifted upward is restricted by the contact portion 22 of the protrusion 20 coming into contact with the restriction portion 19 of the restriction means 17.
Thereby, the electric power feeder 2 pulls up the wire harness 3 extended toward the harness fixing | fixed part 15 by the side of the vehicle body from the harness holding | maintenance part 12 of the 2nd arm 7, and prevents the excess length of the wire harness 3 from drooping. In addition, the power feeding device 2 avoids the second arm 7 from coming into direct contact with the regulating means 17 by the protrusion 20 that comes into contact with the regulating means 17. (See Figure 1)
Since the wire harness 3 is pulled forward with the harness fixing portion 16 on the vehicle body side as a fulcrum in the opened state of the slide door 1, the power feeding device 2 is configured so that the first arm 6 resists the urging force of the torsion coil spring 9. The second arm 7 is slightly rotated downward in the counterclockwise direction (anti-extra length absorption direction), and rotated so that the tip side is directed obliquely rearward. At this time, the movement of the second arm 7 that is pulled down is restricted by the contact portion 22 of the projection 20 contacting the restriction portion 19 of the restriction means 17.
As a result, the power feeding device 2 lifts the wire harness 3 by the biasing force of the torsion coil spring 9 between the harness holding portion 12 of the second arm 7 and the harness fixing portion 16 on the vehicle body side, and is in a moderately tensioned state. Hold and absorb the extra length of the wire harness 3. (See Figure 2)

一方、給電装置2は、開放状態のスライドドア1を閉鎖状態へ動作させる場合に、第2アーム7のハーネス保持部12が車体側のハーネス固定部16を超えて前方に移動すると、ワイヤハーネス3が車体側のハーネス固定部16を支点に後方に引かれる。このとき、給電装置2は、後方に引かれるワイヤハーネス3によって、捩りコイルばね9の付勢力に抗して第1アーム6が反時計方向(反余長吸収方向)に回転され、第2アーム7が下方に引き下げられて先端側を後方に向けるように回転する。下方に引きげられる第2アーム7は、突起部20の接触部22が規制手段17の規制部19に接触しているので、回転を規制される。
これにより、給電装置2は、第2アーム7のハーネス保持部12と車体側のハーネス固定部16との間で、捩りコイルばね9の付勢力によってワイヤハーネス3を適度に緊張した余長の無い状態に保持する。また、給電装置2は、突起部20の接触部22が規制手段17の規制部19に接触しているので、下方に引きげられる第2アーム7の規制手段17への直接的な接触を回避する。
On the other hand, when the power supply device 2 moves the open state sliding door 1 to the closed state and the harness holding portion 12 of the second arm 7 moves forward beyond the harness fixing portion 16 on the vehicle body side, the wire harness 3 Is pulled backward with the harness fixing portion 16 on the vehicle body side as a fulcrum. At this time, in the power feeding device 2, the first arm 6 is rotated counterclockwise (anti-extra length absorption direction) against the urging force of the torsion coil spring 9 by the wire harness 3 pulled rearward, and the second arm 7 is pulled down and rotates so that the tip side is directed backward. The rotation of the second arm 7 pulled downward is restricted because the contact portion 22 of the protrusion 20 is in contact with the restriction portion 19 of the restriction means 17.
Thereby, the electric power feeder 2 does not have the length which moderately tensioned the wire harness 3 with the urging | biasing force of the torsion coil spring 9 between the harness holding | maintenance part 12 of the 2nd arm 7, and the harness fixing | fixed part 16 by the side of a vehicle body. Keep in state. Moreover, since the contact part 22 of the projection part 20 is contacting the regulation part 19 of the control means 17, the electric power feeding apparatus 2 avoids the direct contact to the control means 17 of the 2nd arm 7 pulled down. To do.

このように、給電装置2は、スライドドア1の開閉時において、回動する第1アーム6・第2アーム7の移動量を規制手段17によって規制することにより、ワイヤハーネス3が余長吸収方向に過度に牽引されることを防止でき、スライドドア1の開閉時にワイヤハーネス3の保護が可能になる。
また、給電装置2は、スライドドア1の開閉時に、第2アーム7が規制手段17に接触することで、ヒンジ部14が損傷して第2アーム7が破損される恐れがあり、さらに、第2アーム7の先端と規制手段17が引っ掛かり、第2アーム7のスムーズな開閉動作を妨げることがある。
この給電装置2は、規制手段17と接触する第2アーム7の先端に突起部20を設け、スライドドア1の開閉時において、第1アーム6・第2アーム7の移動量を規制手段17によって規制する際に、第2アーム7の先端に設けた突起部20により第2アーム7の規制手段17への直接的な接触を回避する機能を備えている。
これにより、給電装置2は、第2アーム4と規制手段17の引っ掛かりを防止することができ、第2アーム7の往復移動の動きがスムーズになる。また、給電装置2は、第2アーム7と規制手段17の直接的な接触および摺動による摩擦を回避することができ、第2アーム7の破損を防止できる。
なお、上述実施例においては、ワイヤハーネス3の長さをスライドドア1の閉鎖時に車体側との間の引き回しに必要な長さに設定し、スライドドア1の半開時に生じるワイヤハーネス3の余長を吸収する機能を備える給電装置2を例示した。しかし、ワイヤハーネス3の長さをスライドドア1の開放時に車体側との間の引き回しに必要な長さに設定し、スライドドア1の半開時に生じるワイヤハーネス3の余長を吸収する機能を備える給電装置についても、実施が可能である。
As described above, when the sliding door 1 is opened / closed, the power feeding device 2 regulates the amount of movement of the first arm 6 and the second arm 7 that rotate by the regulating means 17, so that the wire harness 3 can absorb the extra length. The wire harness 3 can be protected when the sliding door 1 is opened and closed.
In addition, when the sliding door 1 is opened and closed, the power feeding device 2 may cause the hinge portion 14 to be damaged and the second arm 7 to be broken due to the second arm 7 coming into contact with the regulating means 17. The tip of the two arms 7 and the restricting means 17 may be caught, and the smooth opening / closing operation of the second arm 7 may be hindered.
The power feeding device 2 is provided with a protrusion 20 at the tip of the second arm 7 that contacts the restricting means 17, and the amount of movement of the first arm 6 and the second arm 7 is controlled by the restricting means 17 when the slide door 1 is opened and closed. When regulating, the projection 20 provided at the tip of the second arm 7 has a function of avoiding direct contact of the second arm 7 with the regulating means 17.
Thereby, the electric power feeder 2 can prevent the 2nd arm 4 and the control means 17 from being caught, and the movement of the 2nd arm 7 reciprocatingly becomes smooth. Further, the power feeding device 2 can avoid friction caused by direct contact and sliding between the second arm 7 and the regulating means 17, and can prevent the second arm 7 from being damaged.
In the above-described embodiment, the length of the wire harness 3 is set to a length required for routing to the vehicle body side when the slide door 1 is closed, and the extra length of the wire harness 3 generated when the slide door 1 is half opened. The electric power feeder 2 provided with the function which absorbs is illustrated. However, the length of the wire harness 3 is set to a length necessary for routing to the vehicle body side when the slide door 1 is opened, and a function of absorbing the extra length of the wire harness 3 generated when the slide door 1 is half opened is provided. The power supply apparatus can also be implemented.
