Abstract
A vibration damping device which is able to damp vibration of a rotating body in a high-speed range and to certainly accelerate the rotating body to the high-speed range is provided. A vibration damping devicedamping vibration of a rotating bodyincludes an automatic balancerwhich is configured to cancel out imbalance of the rotating bodywhen the rotating body rotates; a liquid damperwhich is coaxially rotatable with the rotating bodyand includes a collision memberprovided in a casingin which liquidis sealed, the liquid colliding with the collision memberwhen the liquidmoves in a circumferential direction; and a relative rotation unitwhich is configured to cause the liquid damperto rotate relative to the rotating body
