Claim 0:
1. A motor apparatus having a motor, comprising:
a fan that is rotatably supported by a shaft member of the motor, and is configured to take gas from an axial direction of the shaft member and send the gas in a centrifugal direction by rotation; 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,
wherein the cover member has a blowout port that blows out a part of the gas sent in the centrifugal direction from the fan in the centrifugal direction to cool an external mechanism of the motor apparatus,
the motor includes a motor case that stores a stator and a rotor,
the motor case has a protruding part that protrudes in the axial direction between the fan and the cover member so as to surround, in the centrifugal direction, a side of the fan, and
the protruding part has an opening between the fan and the blowout port of the cover member, such that the part of the gas sent in the centrifugal direction from the fan passes through the opening and is blown out from the blowout port.
