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

Vibration damping device and bobbin holder system

A liquid damper system for restraining vibrations generated in a rotating body includes: a liquid damper which is coaxially rotatable with the rotating body and includes a collision member, the collision member being provided in a casing in which liquid is enclosed and the liquid colliding with the collision member when moving in the circumferential direction; and a relative rotation unit configured to cause the liquid damper to rotate relative to the rotating body. Vibrations of a rotating body are effectively suppressed when a rotating body steadily rotates at a main resonance frequency, in the liquid damper system.
