The insertion portion includes a connecting passage that connects the internal space and an external space. The valve structure includes a valve member in the connecting passage, a locking portion that restricts displacement of the valve member, and a spring that presses the valve member against the locking portion.

Abstract: A second wire harness passing under a cooling pipe is restricted by a restricting member to a position outside a plane that passes through a cooling oil hole and is perpendicular to a longitudinal direction of the cooling pipe. Thus, it is possible to prevent cooling oil released through the cooling oil hole from splashing onto the second wire harness, without having to dispose the second wire harness above the cooling pipe. As the cooling oil released through the cooling oil hole is efficiently supplied to a first rotating electrical machine, the performance of cooling the first rotating electrical machine is enhanced.
