Zusammenfassung:A motor apparatus having a motor comprises: a fan that is rotatably supported by a shaft member of the motor, and sends, in a centrifugal direction by rotation, gas taken from an axial direction of the shaft member; and a cover member that covers the fan so as to allow the gas sent in the centrifugal direction from the fan to flow along an outer surface of the motor. The cover member has a blowout port that blows out some of the gas sent in the centrifugal direction from the fan in the centrifugal direction to cool an external mechanism of the motor apparatus.
