To provide a vehicular driving device, whose dimension in an axial direction is suppressed to be small, which is configured to facilitate supply of oil to a first engagement device.SOLUTION: A first engagement device CL1 that connects and disconnects power transmission between an input member 1 that is connected to an internal combustion engine to drive and a rotating electric machine MG and a second engagement device CL2 that connects and disconnects power transmission between a pump impeller and a turbine runner 52 are arranged to overlap with each other in a view in a radial direction along a radial direction R. A first inner support member 44 of the first engagement device CL1 is connected to a second outer support member 60 of the second engagement device CL2 to rotate integrally. An inner peripheral surface of the first inner support member 44 and an outer peripheral surface of the second outer support member 60 oppose to each other in the radial direction R. Between the inner peripheral surface of the first inner support member 44 and the outer peripheral surface of the second outer support member 60 in the radial direction R is formed a first oil passage P1 extending in the axial direction L, and a second oil passage P2 communicating with the first oil passage P1 is formed to penetrate, in the radial direction R, through the first inner support member 44.SELECTED DRAWING: Figure 3
【課題】軸方向の寸法を小さく抑えつつ、第1係合装置に油を供給し易い車両用駆動装置を提供する。【解決手段】内燃機関に駆動連結される入力部材1と回転電機MGとの間の動力伝達を断接する第1係合装置CL1と、ポンプインペラとタービンランナ52との間の動力伝達を断接する第2係合装置CL2とが、径方向Rに沿う径方向視で互いに重複するように配置され、第1係合装置CL1の第1内側支持部材44は、第2係合装置CL2の第2外側支持部材60と一体的に回転するように連結され、第1内側支持部材44の内周面と第2外側支持部材60の外周面とが径方向Rに対向し、第1内側支持部材44の内周面と第2外側支持部材60の外周面との径方向Rの間に、軸方向Lに延在する第1油路P1が形成され、第1油路P1に連通する第2油路P2が、第1内側支持部材44を径方向Rに貫通するように形成されている。【選択図】図3
