Title:
VIBRATION DAMPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/057681
Kind Code:
A1
Abstract:
This vibration damping device includes: a supporting member which rotates integrally with rotating elements; restoring force generation members which are rotatably connected to the supporting member with first connecting shafts interposed therebetween; an inertia mass body which is rotatable about the center of rotation of the rotating elements; second connecting shafts which are each supported by one of the corresponding restoring force generation member and the inertia mass body, and connects the restoring force generation member and the inertia mass body in a relative rotatable manner; and guide portions which are each formed on the other side of the corresponding restoring force generation member and the inertia mass body, and guides the corresponding second connecting shaft. With the rotation of the supporting member, each of the second connecting shafts rocks about the corresponding first connecting shaft while maintaining the center distance to the first connecting shaft constant, and rocks about a virtual shaft while maintaining the center distance to the virtual shaft constant, the virtual shaft being set so that the relative position with respect to the inertia mass body is invariant.
