Original Abstract Submitted
An EDS includes a motor housing and an inverter housing. The inverter housing includes inverter fins. The motor housing includes forward inclined fins serving as motor fins. The forward inclined fins are provided on an outer peripheral surface. The forward inclined fins are inclined in a circumferential direction with respect to a motor axis. The forward inclined fins extend straight in a direction inclined with respect to the motor axis. The entire of each of the forward inclined fins is an inclined portion. In each of the forward inclined fins, a fin downstream end is located at a position separated from a fin upstream end toward a downstream side in the circumferential direction.
