Drive apparatus

A drive apparatus, comprising:

• a casing including:
• a motor chamber;
• a gear chamber;
• and
• an electric unit chamber, the electric unit chamber having at least a part positioned to be closer to one axial-direction side than the gear chamber;
• a motor housed in the motor chamber and including a motor shaft, the motor shaft having one end on the one axial-direction side positioned in the gear chamber;
• a gear unit housed in the gear chamber and configured to be mechanically connected to the one end of the motor shaft;
• an electric unit housed in the electric unit chamber and configured to be electrically connected to the motor;
• a first route configured to supply a first heat medium configured to cool the motor to the motor;
• a second route configured to supply a second heat medium configured to cool the electric unit to the electric unit;
• and
• a heat exchanger configured to:
• be included on the first route and on the second route;
• exchange heat between the first heat medium and the second heat medium;
• and
• have at least a part that overlaps with the gear chamber in the axial direction and that overlaps with the electric unit chamber in a radial direction perpendicular to the axial direction.
