To further compactly constitute a vehicular driving device which has driving force of an internal combustion engine and a rotary electrical machinery as driving force sources of wheels and includes a distribution differential gear device for dividing the driving force and a transmission.SOLUTION: A vehicular driving device 100 includes: an input shaft X12 which is arranged on a first shaft A1; a rotor 21 which is arranged on a second shaft A2; a distribution differential gear mechanism 10 which is arranged on the first shaft A1 and in which a first distribution rotation element SG is driven and connected to the input shaft X12 and a third distribution rotation element RG is driven and connected to the rotor 21; a transmission 34 which has gear change engagement devices C2, C3; a transmission gear train GT which performs power transmission between the rotor 21 and the third distribution rotation element RG; and a first engagement device C1 which connects and disconnects power transmission between two rotation elements of three rotation elements in the distribution differential gear mechanism 10. The first engagement device C1 and the gear change engagement devices C2, C3 are arranged to be stored between an end of the transmission gear train GT in an axial direction L and an end of a rotary electrical machinery 2.SELECTED DRAWING: Figure 1

    【課題】内燃機関及び回転電機の駆動力を車輪の駆動力源とし、これらの駆動力を分割する分配用差動歯車装置と変速機とを備えた車両用駆動装置をより小型に構成する。【解決手段】車両用駆動装置100は、第1軸A1上に配置された入力軸X12と、第2軸A2上に配置されたロータ21と、第1軸A1上に配置されて、第1分配用回転要素SGが入力軸X12に駆動連結され、第3分配用回転要素RGがロータ21に駆動連結された分配用差動歯車機構10と、変速用係合装置C2,C3を備えた変速機34と、ロータ21と第3分配用回転要素RGとの間の動力伝達を行う伝動ギヤ列GTと、分配用差動歯車機構10の3つの回転要素のうちの2つの間の動力伝達を断接する第1係合装置C1と、を備える。第1係合装置C1及び変速用係合装置C2,C3が、軸方向Lにおける伝動ギヤ列GTの端部と回転電機2の端部との間に収まるように配置されている。【選択図】図1
