A PCU case of a power control unit includes a case main body that has an upper surface-side opening and a lower surface-side opening and is formed in a tubular shape with a rectangular cross-section, and an upper cover that covers the upper surface-side opening. The case main body includes a fastening part that is formed so as to surround the lower surface-side opening and fastened to a surface of a transaxle case, and this surface of the transaxle case doubles as a lower surface of the PCU case. The case main body includes a plate-shaped beam member that extends along a short-side direction, connects a pair of long-side side walls to each other, and divides the inside of the case main body into an upper chamber and a lower chamber, and an intermediate opening that provides communication between the upper chamber and the lower chamber.
