To provide a vehicular drive device which can reduce a radial dimension to a small dimension.SOLUTION: A vehicular drive device is provided with: a first bearing B1 which supports a second rotary member RT2 in a manner that the second rotary member RT2 can rotate relative to a first rotary member RT1; and a second bearing B2 which supports the first rotary member RT1 in a manner that the first rotary member RT1 can rotate relative to a case 4. The first rotary member RT1 includes: a support outer peripheral surface 11a facing the radial outer side R2; and a first radial support surface 13a facing one side in a radial direction R. The second rotary member RT2 includes a support inner peripheral surface 51a facing the radial inner side R1. A support 41 of the case 4 includes a second radial support surface 41a facing the first radial support surface 13a. The first bearing B1 is disposed between the support outer peripheral surface 11a and the support inner peripheral surface 51a. The second bearing B2 is disposed between the radial support surfaces 13a, 41a. The first bearing B1 is disposed at a position which is located at the radial inner side R1 relative to a rotor Ro and overlaps with the rotor Ro in a radial direction view.SELECTED DRAWING: Figure 3

    【課題】径方向の寸法を小さく抑えることが容易な車両用駆動装置を提供する。【解決手段】車両用駆動装置には、第2回転部材RT2を第1回転部材RT1に対して相対的に回転可能に支持する第1軸受B1と、第1回転部材RT1をケース4に対して相対的に回転可能に支持する第2軸受B2と、が設けられ、第1回転部材RT1は、径方向外側R2を向く支持外周面11aと、径方向Rの一方側を向く第1径方向支持面13aと、を備え、第2回転部材RT2は、径方向内側R1を向く支持内周面51aを備え、ケース4の支持体41は、第1径方向支持面13aに対向する第2径方向支持面41aを備え、第1軸受B1は、支持外周面11aと支持内周面51aとの間に配置され、第2軸受B2は、径方向支持面13a,41aの間に配置され、第1軸受B1が、ロータRoに対して径方向内側R1であって、ロータRoと径方向視で重複する位置に配置されている。【選択図】図3
