The center C of a connecting part 16 matches the center U of lift generated on an airframe of this rotorcraft 10. The center C of the connecting part 16 is the point where gravitational force on a first mounted part and a supporting rod 21 is applied with respect to the connecting part 16. The center U of lift is the point where lift is applied on the rotorcraft 10, and is the rotation center in the connecting part 16. The center U of lift generated on the rotorcraft 10 is located at the center C of the connecting part as described above. Thus, even when the airframe of the rotorcraft 10 becomes tilted, rotation moment caused by heavy objects such as a camera 28 does not occur about the center U of lift since the supporting rod 21 and the first mounted part rotate about the center C of the connecting part. As a result, when a rotorcraft having multiple rotors travels horizontally, the difference in rotation speed between the rotors located forward and backward in the travelling direction can be further reduced than that obtained hitherto. |
