To so make a dimension of a terminal box of an in-wheel motor as to be smaller than that of a conventional one.SOLUTION: An in-wheel motor drive device 10 comprises a wheel hub bearing part 11, and a motor part 21. A terminal box 25 of the motor part has plural conductive bars 26u, 26v, 26w which extend from a motor coil side, and a bolt 46 which connects and fixes plural power line ends 41 and the plural conductive bars on a one-to-one basis inside of the terminal box. Each of the plural conductive bars is provided with an open hole or a screw hole which extends in a prescribed direction and through which the bolt passes. At least two of the plural power line ends 41, 41, 41 are so located as to be overlapped on each other when viewed in an extension direction of the open hole or the screw hole of the bolt 46. The plural bolts 46 are attached to/detached from the conductive bars in the extension direction of the open hole or the screw hole of the bolt 46, and all bolts are so located as not to be overlapped on each other when viewed in the extension direction.SELECTED DRAWING: Figure 2 【課題】インホイールモータの端子ボックスの寸法を従来よりも小型化する。【解決手段】インホイールモータ駆動装置１０は、車輪ハブ軸受部１１と、モータ部２１とを備える。モータ部の端子ボックス２５は、モータコイル側から延びる複数の導電棒２６ｕ，２６ｖ，２６ｗと、端子ボックス内部で複数の動力線端部４１と複数の導電棒を１対１で接続固定するボルト４６を有する。複数の導電棒にはそれぞれ、所定方向に延びてボルトが通される貫通孔またはねじ穴が設けられる。複数の動力線端部４１，４１，４１のうち少なくとも２つは、ボルト４６の貫通孔またはねじ穴の延在方向にみて互いに重なるように配置される。複数のボルト４６は、ボルト４６の貫通孔またはねじ穴の延在方向に導電棒に着脱され、かかる延在方向にみて全て重ならないように配置される。【選択図】図２
