To provide an in-wheel motor type vehicle driving device which enables a pinion gear to be set to have a predetermined speed reduction ratio while inhibiting size increase and complication of an electric motor.SOLUTION: An in-wheel motor type vehicle driving device 100 includes an electric motor 3 and a planetary gear mechanism 5 to which driving force of the electric motor 3 is transmitted. The planetary gear mechanism 5 includes a pinion gear 51 having a first pinion 51a and a second pinion 51b coaxially arranged with the first pinion 51a and having a diameter smaller than the first pinion 51a. The first pinion 51a is disposed at a position which is away from a stator core 32 farther than an end part of the stator core 32 in a direction in which a rotation center axis C2 of a wheel W extends.SELECTED DRAWING: Figure 3

    【課題】電気モータの大型化および複雑化を抑制しながら、ピニオンギヤを所望の減速比に設定することが可能なインホイールモータ型の車両駆動装置を提供する。【解決手段】このインホイールモータ型の車両駆動装置100は、電気モータ3と、電気モータ3の駆動力が伝達される遊星歯車機構5とを備える。遊星歯車機構5は、第1ピニオン51aと、第1ピニオン51aと同軸で第1ピニオン51aより小径な第2ピニオン51bとを有するピニオンギヤ51を含む。第1ピニオン51aは、ホイールWの回転中心軸線C2が延びる方向において、ステータコア32の端部よりもステータコア32から離れる方向に位置に配置されている。【選択図】図3
