To provide a multicopter capable of reducing a burden of a worker or a lifting device when lifting a tip end of a horizontal rotator arm capable of vertically swiveling.SOLUTION: A rotor aircraft includes a horizontal rotor, an arm 41 that supports the horizontal rotor, and a body portion connected with the arm. The arm can vertically swivel using a connecting portion 45 with the body portion as a rotation center. The arm has a battery holding portion 43 to which a battery 37 that is a power source of the horizontal rotor is installed. When a rotation center A of the arm is viewed from an axial direction thereof, assuming an area on a center side of the body portion of two areas divided by a vertical straight line V passing through the rotation center as a back portion of the rotation center, a gravity center position G of a battery installed to the battery holding portion is disposed on the back portion of the rotation center, in at least a part of a track R moved by swiveling of the arm.SELECTED DRAWING: Figure 7

    【課題】上下に旋回可能な水平回転翼アームの先端を持ち上げるときに、これを行う作業者または昇降装置の負担を軽減することのできるマルチコプターを提供する。【解決手段】水平回転翼と、水平回転翼を支持するアーム41と、アームが接続される胴部と、を備え、アームは、胴部との接続部45を回転中心として上下に旋回可能であり、アームは、水平回転翼の動力源であるバッテリー37が装着されるバッテリー保持部43を有し、アームの回転中心Aをその軸線方向から見たときに、該回転中心を通る鉛直線Vにより区分けされる2つの領域のうち胴部の中心側の領域を回転中心の背部としたときに、バッテリー保持部に装着されたバッテリーの重心位置Gは、アームの旋回により移動する軌道R上の少なくとも一部において、回転中心の背部に配置される。【選択図】図7
