To provide a driving device for a four-wheel drive vehicle which achieves excellent mountability of a motor which drives front wheels.SOLUTION: A four-wheel drive vehicle 10 transmits torque output through a transmission 15 by an engine 11 to a rear wheel axle 13a through a rear propeller shaft 26 and transmits torque output by a front driving motor 22 to a front wheel axle 14a through a front propeller shaft 27. A front wheel driving unit 20 is disposed between the transmission 15 and the rear wheel axle 13a. The front wheel driving unit 20 includes: a main shaft 19 which transmits the torque output by the transmission 15 to the rear propeller shaft 26; a sub-shaft 25 which is disposed at a position offset from the front driving motor 22 and the main shaft 19 in a vehicle width direction and transmits the torque output by the front driving motor 22 to the front propeller shaft 27; and a case 24 which houses the main shaft 19, the front driving motor 22, and the sub-shaft 25.SELECTED DRAWING: Figure 1

    【課題】前輪を駆動するモータの搭載性に優れた四輪駆動車用駆動装置を提供する。【解決手段】四輪駆動車10は、変速機15を介してエンジン11が出力したトルクを、リヤプロペラシャフト26を介して後輪車軸13aに向けて伝達し、かつフロント駆動モータ22が出力したトルクを、フロントプロペラシャフト27を介して前輪車軸14aに向けて伝達する。変速機15と後輪車軸13aとの間には、前輪駆動ユニット20が配置される。前輪駆動ユニット20は、変速機15が出力したトルクをリヤプロペラシャフト26に向けて伝達する主軸19と、フロント駆動モータ22と、主軸19に対して車幅方向にずれた位置に配置されておりフロント駆動モータ22が出力したトルクをフロントプロペラシャフト27に向けて伝達する副軸25と、主軸19、フロント駆動モータ22および副軸25を収容するケース24とを備える。【選択図】図1
