Abstract
Disclosed is an electric motorcycle provided with: an electric motor (M) for driving a rear wheel (110) which is a drive wheel; a battery (B) for supplying power to the electric motor (M); and a controller unit (130) for performing drive control of the electric motor (M). The electric motorcycle is of the scooter type in which a footrest section is constructed between the front wheel (105) and the rear wheel (110), and is provided with a controller housing compartment (129) disposed in the footrest section so as to be downwardly recessed. An opening (131) is formed in the bottom of the controller housing compartment (129), and a cooling fin (130c) is provided in the bottom surface of the controller unit (130) in a state in which the cooling fin (130c) is housed in the controller housing compartment (129) and downwardly protrudes from the opening (131) to face the outside. As a result, the controller unit (130) is directly and efficiently cooled by airflow produced during travel.
