To provide a vehicular drive device having structure in which the accuracy of supporting a rotating member connected in a driven manner to a drive force source can be easily improved.SOLUTION: The vehicular drive device comprises a case 5 housing a hydraulic pump 6, a pump cover 7 and a rotation member RT, the case 5 comprises a case portion 51 in which an opening 51a opened toward a first side L1 in an axial direction is formed, and a second case portion 52 joined to the first case portion 51 to close the opening 51a. The pump cover 7 is fixed to the second case portion 52 from a second side L2 in the axial direction in such a way that the hydraulic pump 6 is arranged between the pump cover 7 and the second case portion 52. A bearing BR rotatably supporting the rotation member RT is arranged at the second side L2 in the axial direction with respect to the pump cover 7, the second case portion 52 comprises a support portion 521 extending to the second side L2 in the axial direction at the outside of a radial direction R rather than the pump cover 7, and the support portion 521 supports the bearing BR in the radial direction R.SELECTED DRAWING: Figure 2

    【課題】駆動力源に駆動連結された回転部材の支持精度を高くし易い構造の車両用駆動装置を提供する。【解決手段】車両用駆動装置において、油圧ポンプ6、ポンプカバー7、及び回転部材RTを収容するケース5は、軸方向第1側L1に向けて開口する開口部51aが形成された第1ケース部51と、開口部51aを塞ぐように第1ケース部51に接合された第2ケース部52と、を備え、ポンプカバー7は、当該ポンプカバー7と第2ケース部52との間に油圧ポンプ6が配置されるように、軸方向第2側L2から第2ケース部52に固定され、回転部材RTを回転可能に支持する軸受BRが、ポンプカバー7に対して軸方向第2側L2に配置され、第2ケース部52は、ポンプカバー7よりも径方向Rの外側において、軸方向第2側L2に延在する支持部521を備え、支持部521が軸受BRを径方向Rに支持している。【選択図】図2
