Document Type and Number:

WIPO Patent Application WO/2018/180056

Kind Code:

A1

Abstract:

Provided is a vibration damping device that is able to suppress vibration of a rotating body in a high-speed region, and that enables the rotating body to accelerate up to the high-speed region reliably. This vibration damping device (1) for suppressing vibration of a rotating body (100) is equipped with: an automatic balancer (2) that cancels out an imbalance of the rotating body (100) when the rotating body (100) rotates; a fluid damper (4) that is able to rotate coaxially with the rotating body (100), and that is provided with a collision part (23) that collides with a fluid (22) sealed in a case (20) when the fluid (22) moves in the circumferential direction; and a relative rotation means (5) that causes the fluid damper (4) to rotate relative to the rotating body (100).
