PROBLEM TO BE SOLVED: To provide a helicopter which need not require any large actuator of heavy weight and high energy consumption and is designed at low cost in order to reduce the vibration. SOLUTION: A helicopter has a rotor (2), a fuselage (3) connected to the rotor (2) by connecting means (4), and a control device (6) for controlling vibration of the fuselage (3); the control device (6) including generating means (7) for generating signals associated with vibration of the fuselage (3), and actuating means (8) for producing a force on the fuselage (3) associated with the signals to reduce vibration; and the actuating means (8) is carried by the connecting means (4).
