摘要： A drive unit for vehicle travel has the engine and a motor 14. The motor 14 is arranged adjacent to a rear side of the engine. In housings 14a, 14b of the motor 14, parts of oil control valves 45, 46 and motor cooling oil paths LN11 to LN12, LN21to LN22, LN31 to LN35, through each of which motor cooling oil flows, are provided. The motor cooling oil flowing through the motor cooling oil paths LN11, LN31 exchanges heat with engine oil in a heat exchanger 42. The motor cooling oil flowing through the motor cooling oil paths LN12, LN32 exchanges heat with an engine cooling coolant in a heat exchanger 43.
