The EDS (50) has a motor housing (70) and an inverter housing (90). The inverter housing (90) has inverter fins (92). The motor housing (70) is provided with clockwise inclined fins (721) as motor fins (72). The clockwise inclined fins (721) are provided on the outer peripheral surface (70a). The clockwise inclined fins (721) are inclined in the circumferential direction (CD) with respect to the motor axis (Cm). The clockwise inclined fins (721) extend straightly in a direction inclined with respect to the motor axis (Cm). The whole of the clockwise inclined fins (721) forms an inclined part. In the clockwise inclined fins (721), the fin downstream ends (72b) are located at positions farther from the fin upstream ends (72a) toward the downstream side in the circumferential direction (CD).
EDS(50)具有电动机外壳(70)和逆变器外壳(90)。逆变器外壳(90)具有逆变器翅片(92)。电动机外壳(70)具有作为电动机翅片(72)的顺倾斜翅片(721)。顺倾斜翅片(721)设置于外周面(70a)。顺倾斜翅片(721)相对于电动机轴线(Cm)在周向(CD)上倾斜。顺倾斜翅片(721)沿相对于电动机轴线(Cm)倾斜的方向笔直地延伸。顺倾斜翅片(721)的整体成为倾斜部。在顺倾斜翅片(721)中,翅片下游端(72b)位于从翅片上游端(72a)向周向(CD)的下游侧远离的位置。
