Abstract
A drive unit includes a prime mover, a torque converter, and a torque converter casing. The torque converter is configured to amplify a torque generated by the prime mover. The torque converter is disposed to be rotatable. The torque converter casing is disposed to be non-rotatable. The torque converter casing accommodates the torque converter. The torque converter casing includes a first air intake port and a first air discharge port. The first air intake port is configured to draw air into the torque converter casing therethrough. The first air discharge port is configured to discharge the air inside the torque converter casing therethrough. The drive unit allows the torque converter to be cooled.
