PROBLEM TO BE SOLVED: To improve the rigidity of casings for housing two reduction gears and electric motors without causing large weight increase in a two-motor vehicle drive device having a structure of centering the two reduction gears and fixedly disposing the two electric motors on the right and left of the reduction gears.SOLUTION: Both or one of right and left motor casings 3R, 3L for housing right and left electric motors 1R, 1L and right and left fixed walls 20bRa, 20bLa, which are provided on a reduction gear casing 20 and to which the right and left motor casings 3R, 3L are fixed, are connected to each other for reinforcement with support bars 6 so that, without causing large weight increase, the rigidity of the right and left motor casings 3R, 3L against a deformation mode can be improved, and a power line 4 is supported on the support bars 6 so that swaying of the power line 4 during travel can be reduced.SELECTED DRAWING: Figure 2 【課題】２基の減速機を中央にし、その左右に２基の電動モータを固定配置する構造の２モータ車両駆動装置において、２基の減速機と電動モータを収容するケーシングの剛性を大幅な重量増を起こすことなく、向上させる。【解決手段】左右の電動モータ１Ｌ、１Ｒを収容する左右のモータケーシング３Ｌ、３Ｒ相互間と、左右のモータケーシング３Ｌ、３Ｒを固定する減速機ケーシング２０に設けられた左右の固定壁２０ｂＬａ、２０ｂＲａ相互間の両方又は一方をサポートバー６によって繋いで補強することにより、大幅な重量増を起こすことなく、左右のモータケーシング３Ｌ、３Ｒの変形モードに対する剛性を向上させることができ、サポートバー６に動力線４を支持することにより、走行中における動力線４の揺動を軽減させることができる。【選択図】図２
