The airframe includes a body having a hollow portion, and a plurality of through holes connected to the hollow portion and formed on an outer peripheral surface of the body. The airframe also includes a plurality of arms supporting the plurality of propellers, and each arm of the plurality of arms includes a base end portion disposed at a body side in a longitudinal direction of the respective arm. The base end portion is inserted in a corresponding through hole of the plurality of through holes and supported by the body. Each arm of the plurality of arms is configured to be stored in the hollow portion of the body by being retracted into the body via the through hole, and expanded out of the body by being pulled out of the body via the through hole.
