To provide an in-wheel motor type vehicle driving device which enables reduction of the number of components of an oil pump and can inhibit increase of an axial dimension of the in-wheel motor type vehicle driving device.SOLUTION: An in-wheel motor type vehicle driving device 100 includes: a driven gear 41 having a first wall surface S1 for forming a pump chamber S which an oil is suctioned into or discharged from; and an oil pump 7 which is driven by an electric motor 3. The oil pump 7 includes: an oil pump cover 171 having a second wall surface S2 facing the first wall surface S1 of the pump chamber S; and an inner rotor 72 and an outer rotor 73 disposed in a space between the first wall surface S1 and the second wall surface S2 and serving as a pump rotating body which integrally rotates as the driven gear 41 rotates.SELECTED DRAWING: Figure 3

    【課題】オイルポンプの部品点数を減少させることができるとともに、インホイールモータ型の車両駆動装置の軸方向の寸法の増加を抑制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、オイルが吸入および吐出されるポンプ室Sを形成するための第1壁面S1を有する従動ギヤ41と、電気モータ3により駆動されるオイルポンプ7とを備える。オイルポンプ7は、ポンプ室Sの第1壁面S1に対向する第2壁面S2を有するオイルポンプカバー171と、第1壁面S1と第2壁面S2との間の空間に配置され、従動ギヤ41の回転に伴って一体的に回転するポンプ回転体であるインナーロータ72およびアウターロータ73とを含む。【選択図】図3
