A cabin 1 of a helicopter is separated structurally from an airframe 2, and the cabin is supported on the airframe 2 by using both springs 6 and actuators 7. The high frequency vibration, which is the mast uncomfortable high frequency component of the number of revolutions of rotor, is absorbed by soft springs, and the resonance of the spring and the rotor rotation is actively inhibited by actuators, so that the vibrations of wide frequency is removed from the cabin, thereby achieving comfortableness to ride in the helicopter.
