To provide a driving device for a hybrid vehicle which has a motor connected to a transmission case by a speed reducer case and can inhibit vibration of the motor while simplifying a structure of the speed reducer case.SOLUTION: In a driving device 4, a left case 7 of a transmission case 5 includes a speed reducer case 25 which houses a speed reduction mechanism 33. The speed reducer case 25 has: a case part 26 which is formed integrally with the left case 7 and encloses the speed reduction mechanism 33; and a cover part joined to the case part 26. The case part 26 has a side wall part 29 extending upward from an upper wall 7B of the left case 7 and located between the motor 32 and the speed reduction mechanism 33. The side wall part 29 has a disc-like motor attachment part 29 which has an outer diameter equivalent to an outer diameter of the motor 32 and to which the motor 32 is connected. Multiple boss parts and bolts 23C which fasten the motor 32 to the motor attachment part 29C are provided at an outer periphery part of the motor attachment part 29C.SELECTED DRAWING: Figure 5

    【課題】減速機ケースによって変速機ケースに連結されるモータを有するハイブリッド車両用駆動装置において、減速機ケースの構造を簡素化しつつ、モータの振動を抑制できるハイブリッド車両用駆動装置を提供すること。【解決手段】駆動装置4は、変速機ケース5のレフトケース7が減速機構33を収容する減速機ケース25を備えており、減速機ケース25は、レフトケース7に一体に形成され、減速機構33を取り囲むケース部26と、ケース部26に接合されたカバー部とを有し、ケース部26は、レフトケース7の上壁7Bから上方に延び、モータ32と減速機構33との間に位置する側壁部29を有する。側壁部29は、モータ32の外径と同等の外径を有し、モータ32が連結される円盤状のモータ取付部29Cを備えており、モータ取付部29Cの外周部に、モータ32をモータ取付部29Cに締結する複数のボス部およびボルト23Cが設けられている。【選択図】図5
