A cooling system includes: (a) a first pump to be driven with vehicle running; (b) a lubricating passage for supplying the lubricant from the first pump, to a lubrication-required part; (c) a second pump to be driven by a drive source other than a drive source of the first pump; (d) a cooling passage for supplying the lubricant from the second pump, to a rotary electric machine via a heat exchanger provided in the cooling passage; (e) a connecting passage connecting between the lubricating passage and the cooling passage, and (f) a lubricant distribution portion configured to change a connecting-passage flowing amount of the lubricant that flows through the connecting passage, depending on a temperature of the lubricant, such that a ratio of the connecting-passage flowing amount to a lubricating-passage flowing amount of the lubricant that flows through the lubricating passage is increased with increase of the lubricant temperature.
