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.

    电力控制单元的PCU壳体包括:壳体主体,其具有上表面侧开口和下表面侧开口,并形成为呈矩形截面的管状;以及上盖,其覆盖上表面侧开口。壳体主体包括紧固部,该紧固部形成为以便包围下表面侧开口并紧固至驱动桥壳体的表面,以及驱动桥壳体的该表面兼作PCU壳体的下表面。壳体主体包括板形的梁构件和中间开口,该板形的梁构件沿着短边方向延伸,将一对长边侧壁彼此连接,并将壳体主体的内部划分为上腔室和下腔室,该中间开口提供上腔室与下腔室之间的连通。
