Zusammenfassung:	To provide a drive unit which can suppress damage of a fastening part concerning fixing of a motor, an inverter and an electric module also in vehicle collision while achieving reduction in the inverter.SOLUTION: In a driving unit, an inverter 92 having an inverter case 92a and a junction box 94 having an outer packaging case 94a are mounted in this order on a motor 91 having a motor case 91a. A first fastening part for allowing a bolt 12 to insert a through hole 94d of the outer packaging case 94a and a through hole 92c of the inverter case 92a, and fastening the outer packaging case 94a, the inverter case 92a and the motor case 91a by screwing with a female screw 91f of the motor case 91a is provided. A second fastening part for allowing the bolt to insert the through hole of the outer packaging case 94a, and fastening the outer packaging case 94a and the inverter case 92a by screwing with a male screw of the inverter case 92a is provided.SELECTED DRAWING: Figure 4 【課題】インバータの軽量化を図りながら、車両衝突時にもモータとインバータと電気モジュールとの固定に係る締結部の損傷を抑制することができる駆動ユニットを提供する。【解決手段】駆動ユニットは、モータケース９１ａを有するモータ９１の上に、インバータケース９２ａを有するインバータ９２、外装ケース９４ａを有するジャンクションボックス９４、が順に載置されている。ボルト１２が外装ケース９４ａの通し孔９４ｄとインバータケース９２ａの通し孔９２ｃを挿通し、モータケース９１ａの雌ネジ９１ｆとの螺結により、外装ケース９４ａとインバータケース９２ａとモータケース９１ａとを締結する第１締結部が設けられている。また、ボルトが外装ケース９４ａの通し孔を挿通し、インバータケース９２ａの雌ネジとの螺結により、外装ケース９４ａとインバータケース９２ａとを締結する第２締結部が設けられている。【選択図】図４
