To prevent that bending and elongation at a specified point are repeated every time an in-wheel motor drive unit is displaced, in a power line extending to a vehicle body from the in-wheel motor drive unit.SOLUTION: A wiring structure of an in-wheel motor power line 93 includes: an intermediate point which is gripped by an intermediate clamp part 94, and extends to a vertical direction; first slack regions 93d, 93e and 93f which downwardly extend from an in-wheel motor drive unit 10 side, and are slacken so as to be gradually changed in orientations from downward orientations to upward orientations as progressing toward the intermediate point; and a second slack region 93g which upwardly extends from the intermediate point, and is slacken so as to be gradually changed in an orientation so that an inclination angle becomes small as progressing toward a vehicle body side. The intermediate clamp part is arranged at a vehicle body 101 or a suspension device so as to be movable to at least a vertical direction. When the in-wheel motor drive unit is relatively displaced with respect to the vehicle body, the intermediate clamp part moves in a vertical direction, and slack shapes of the first slack region and a second slack region are changed.SELECTED DRAWING: Figure 14
【課題】インホイールモータ駆動装置から車体へ延びる動力線において、インホイールモータ駆動装置が変位する度に特定の箇所で曲げ伸ばしが繰り返されることを防止する。【解決手段】インホイールモータ動力線93の配線構造は、中間クランプ部94に把持されて上下方向に延びる中間箇所と、インホイールモータ駆動装置10側から下向きに延びて中間箇所に向かうほど下向きから上向きへ徐々に向きを変えるようにたるむ第1たるみ領域93d,93e,93fと、中間箇所から上向きに延び車体側に向かうほど傾斜角度が少なくなるよう徐々に向きを変えるようたるむ第2たるみ領域93gを含む。中間クランプ部は少なくとも上下方向に移動可能に車体101あるいはサスペンション装置に設けられる。インホイールモータ駆動装置が車体に対して相対変位すると中間クランプ部が上下方向に移動するとともに第1たるみ領域および第2たるみ領域のたるみ形状が変化する。【選択図】図14
