Abstract
A drive unit has engines and a motor that are adjacent to each other in a longitudinal direction. The engines are provided with an engine oil path and a coolant path for cooling. The motor is provided with a motor cooling oil path for cooling. A first heat exchanger, in which engine oil and motor cooling oil exchange heat, and a second heat exchanger, in which a coolant and the motor cooling oil exchange heat, are provided. A second size in vertical and lateral directions of the motor is smaller than a first size in the vertical and lateral directions of each of the engines. The second heat exchanger is attached to an upper portion of a side circumferential portion of the motor, and the first heat exchanger is attached to a lower portion of the side circumferential portion of the motor.
