Title:
VIBRATION-DAMPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/047938
Kind Code:
A1
Abstract:
[Problem] To improve vibration-damping performance. [Solution] This vibration-damping device is provided with a concave-surface-shaped guide surface 23 formed in a support member 21 so as to curve toward the outer periphery of the support member 21, a mass object 30 that rolls over the guide surface 23 while being pushed against the guide surface 23 by centrifugal force accompanying the rotation of the support member 21, and an inertia ring 40 that is rotatably linked to the mass object 30 and that swings around the rotational center of the support member 21. When in a state of equilibrium, the center of gravity of the mass object 30 is positioned farther radially outward than is the position where the mass object 30 and the inertia ring 40 are linked. When the support member 21 rotates, the inertia ring 40 swings relative to the support member 21 around the rotational center of the support member 21, and the mass object 30 rolls over the guide surface 23.
