Abstract: An electric vehicle is provided with a drum brake unit on a rear wheel rotated by drive force of an electric motor. A first set of fins, for cooling the electric motor and the drum brake unit, are provided between the electric motor and the drum brake unit. Specifically, the first set of fins are provided on an inner side surface of a case body. It is possible to cool the electric motor using the first set of fins, and it is also possible to remove heat of the drum brake unit using the first set of fins. The fins act as a heat sink to dissipate heat generated by the drum brake unit, and to resist heat transfer from the drum brake unit to the electric motor, helping to more efficiently cool the electric motor.
