A torque converter is disclosed. The torque converter includes a cover, an impeller, a turbine, a stator, and a first one-way clutch. A torque outputted from a prime mover is inputted to the cover. The impeller is unitarily rotated with the cover. The turbine is opposed to the impeller. The stator is disposed between the impeller and the turbine. The first one-way clutch is configured to make the cover rotatable relative to the turbine in a forward rotational direction. The first one-way clutch is further configured to rotate the cover unitarily with the turbine in a reverse rotational direction.

A drive unit is disclosed. The drive unit includes a prime mover, a torque converter, and a power transmission mechanism. A torque is inputted from the prime mover to the torque converter. The power transmission mechanism is disposed between the prime mover and the torque converter. The power transmission mechanism is configured to transmit the torque outputted from the torque converter toward a drive wheel.
