PROBLEM TO BE SOLVED: To reduce whole size of a vehicular drive device including an inverter device.SOLUTION: The invention relates to a drive device for hybrid vehicles. Respective rotation axes A1, A2, A3 of a rotation electric machinery MG, a gear mechanism C, and a differential gear DF are disposed to form a triangle. A capacitor 36 of an inverter device 3 is disposed to overlap with the gear mechanism C viewed from a direction parallel to a first reference surface R1 between a second reference surface R2 and a third reference surface R3, and a conversion unit 31 is disposed to overlap with the gear mechanism C and the capacitor 36 viewed from a direction orthogonal to the first reference surface R1. 【課題】インバータ装置を含めた車両用駆動装置の全体を小型化する。【解決手段】本発明は、ハイブリッド車両用の駆動装置に関する。回転電機ＭＧ、ギヤ機構Ｃ、及び差動歯車装置ＤＦのそれぞれの回転軸心Ａ１，Ａ２，Ａ３が、三角形を形成するように配置されている。インバータ装置３のコンデンサ３６は、第二基準面Ｒ２と第三基準面Ｒ３との間で、第一基準面Ｒ１に平行な方向に見てギヤ機構Ｃと重複するように配置され、変換ユニット３１は、第一基準面Ｒ１に直交する方向に見てギヤ機構Ｃ及びコンデンサ３６と重複するように配置されている。【選択図】図６
