Abstract
An electric propulsion device includes a duct having a cylindrical shape and that includes a stator. A rim includes a rotor rotatable relative to the duct, and a plurality of fins. A bracket supports the duct so as to allow the duct to turn about a turning axis that intersects with the rotation axis of the rim, and a turning actuator that integrally turns the duct and the rim. The turning actuator is fixed to the bracket, and the duct is turnable relative to the bracket.
