Abstract:
A vibration damping device is provided with a first coupling shaft and a a second coupling shaft supported by one of a restoring force generation member and an inertial mass body to couple the restoring force generation member and the inertial mass body so that the restoring force generation member and the inertial mass body are rotatable relative to each other; and a guide portion formed in the other of the restoring force generation member and the inertial mass body to guide the second coupling shaft. The second coupling shaft swings about the first coupling shaft while keeping the interaxial distance between the shafts constant, and swings about a virtual axis, the relative position of which with respect to the inertial mass body is determined to be invariable, while keeping the interaxial distance between the virtual axis and the second coupling shaft constant.

Claim (Index 1):
A vibration damping device that damps vibration of a rotary element, comprising:\n a support member that rotates about a center of rotation of the rotary element together with the rotary element; a restoring force generation member rotatably coupled to the support member via a first coupling shaft; an inertial mass body that is rotatable about the center of rotation; a second coupling shaft that is supported by one of the restoring force generation member and the inertial mass body and that couples the restoring force generation member and the inertial mass body so that the restoring force generation member and the inertial mass body are rotatable relative to each other; and a guide portion that is formed in the other of the restoring force generation member and the inertial mass body and that guides the second coupling shaft, along with rotation of the support member, such that the second coupling shaft swings about the first coupling shaft while keeping an interaxial distance between the first coupling shaft and the second coupling shaft constant, and such that the second coupling shaft swings about a virtual axis, a relative position of which with respect to the inertial mass body is determined to be invariable, while keeping an interaxial distance between the virtual axis and the second coupling shaft constant.
