PROBLEM TO BE SOLVED: To effectively utilize a space in a wheel house, and to reduce the centrifugal whirling of a vehicle body-side power feed wire accompanied by steering.SOLUTION: A motor power feed wire cabling structure comprises: a knuckle 6 which is arranged so as to be steerable around an axial line of a virtual king pin shaft 7 whose upper side is inclined to the inside of a vehicle width direction with respect to a vehicle body; a wheel 2 connected to an axle which is rotatably supported to the knuckle 6; and an in-wheel motor 5 which imparts a drive force to the axle. In the in-wheel drive wheel, there is arranged a multi-wire integrally-rotating power supply terminal 12' which relatively rotatably and electrically connects a movable power feed wire 13b extending from an in-vehicle power supply to a fixed power feed wire 13a extending from the in-wheel motor 5. A tie rod 15 for receiving an input for steering is connected to the knuckle 6 via a ball joint part 15a, the multi-wire integrally-rotating power supply terminal 12' is arranged at the ball joint part 15a of the tie rod 15. 【課題】ホイールハウス内の空間の有効利用を図るとともに、転舵に伴う車体側給電線の振れ回りを低減すること。【解決手段】車体に対し上側が車幅方向内側に傾斜した仮想キングピン軸７の軸線周りに転舵可能に設けられたナックル６と、ナックル６に回転可能に支持された車軸に接続されたホイール２と、車軸に駆動力を与えるインホイールモータ５と、を備える。このインホイールモータ駆動車輪において、インホイールモータ５から延在する固定給電線１３ａと車載電源から延在する可動給電線１３ｂとを、固定給電線１３ａに対し可動給電線１３ｂを相対回転可能に電気的に接続する複数線一体回転電源端子１２'を設ける。ナックル６に、転舵のための入力を受け入れるタイロッド１５を、ボールジョイント部１５ａを介して連結し、複数線一体回転電源端子１２'を、タイロッド１５のボールジョイント部１５ａに配置した。【選択図】図１
