To provide a hybrid drive apparatus with a small number of components and used for a hybrid vehicle, while suppressing vibration of a PCU.SOLUTION: A hybrid drive apparatus 10, for use in a hybrid vehicle, includes: a case 22 for housing a motor 4 that is connected to an engine 1; and a PCU 3 disposed on the case 22. The motor 4 includes a stator 42 fastened to the case 22 using plural bolts 5. In a case where, of the plural bolts 5, at least one is fastened to the case 22 on a front side of the hybrid vehicle, the case 22 has a seating face 22c that contacts with the stator 42. The seating face 22c and the bolt 5 fastened to the case on the front side of the hybrid vehicle are disposed on a point symmetry about a center axis W1 of the stator 42.SELECTED DRAWING: Figure 2 【課題】ＰＣＵの振動を抑制しつつ、部品点数の少ないハイブリッド車両向けハイブリッド駆動装置の提供。【解決手段】エンジン１と連結するモータ４を収納するケース２２を備え、ケース２２の上にＰＣＵ３が設置されているハイブリッド車両向けハイブリッド駆動装置１０である。モータ４は、複数のボルト５を用いてケース２２に締結されたステータ４２を備える。複数のボルト５のうち、少なくとも１つが、ケース２２におけるハイブリッド車両の前側に締結されている場合、ケース２２は、ステータ４２と接触する座面２２ｃを備える。座面２２ｃと、ケースにおけるハイブリッド車両の前側に締結されたボルト５とは、ステータ４２の中心軸Ｗ１に関して点対称に設けられている。【選択図】図２
