An external line that is supplied with oil cooled by a water oil cooler is connected to a first cooling pipe and a second cooling pipe, so oil cooled by the water O/C is supplied to the first cooling pipe and the second cooling pipe. As a result, it is possible to effectively cool a rotary electric machine by using oil that is supplied from the first cooling pipe and the second cooling pipe to the rotary electric machine. The external line that is supplied with oil cooled by the water O/C is connected to the second cooling pipe via a connection fluid passage defined within a case, so the case is cooled by oil. Thus, the influence of outside air temperature on the rotary electric machine is reduced.
