摘要：
A drive unit includes an electric motor, an MCU to supply a driving current to the electric motor, and a bracket fixing the MCU to the electric motor with a gap between the MCU and the electric motor. The electric motor includes a stator case accommodating a stator, a first housing including a bearing that supports one side of an output shaft of a rotor, and a second housing including a bearing that supports another side of the output shaft of the rotor. The bracket supporting the MCU is attached to the first housing and the second housing and not to the stator case.
