To reduce manufacturing costs for an electric automobile by making an electric automobile driving device common whatever total vehicle weight the electric automobile has.SOLUTION: A pair of driving shafts 4a, 4b are supported coaxially and rotatably on a housing 2 with tip parts thereof in mutually opposite directions. Respective output shafts 7a of a pair of electric motors 3a are arranged non-coaxially in parallel with each other with tip parts thereof in mutually opposite directions. Rotation torques of the respective output shafts 7a of the pair of electric motors 3a are transmitted to the pair of respective driving shafts 4a, 4b while increased by a pair of torque transmission devices 5a, 5b, respectively.SELECTED DRAWING: Figure 5 【課題】車両総重量にかかわらず、電気自動車用駆動装置を共通化して、電気自動車の製造コストを低減する。【解決手段】一対の駆動軸４ａ、４ｂを、互いに同軸に、かつ、それぞれの先端部を、互いに反対方向に向けた状態でハウジング２に対し回転自在に支持する。一対の電動モータ３ａのそれぞれの出力軸７ａを、それぞれの先端部を互いに反対方向に向けた状態で、互いに非同軸に、かつ、互いに平行に配置する。一対の電動モータ３ａのそれぞれの出力軸７ａの回転トルクを、一対のトルク伝達装置５ａ、５ｂのそれぞれにより増大させつつ、一対の駆動軸４ａ、４ｂのそれぞれに伝達する。【選択図】図５
