1. A vibration damping device comprising:
a supporting member that rotates integrally with a rotation element, to which torque from an engine is transmitted, around a rotation center of the rotation element;
a restoring force generation member that is coupled to the supporting member so as to transmit and receive torque to and from the supporting member and that is configured to swing about a swing center offset from the rotation center of the rotation element in accordance with rotation of the supporting member; and
an inertia mass body that is coupled to the supporting member via the restoring force generation member and that swings around the rotation center in conjunction with the restoring force generation member in accordance with rotation of the supporting member, wherein
the restoring force generation member swings around the swing center that is set so that a relative position of the swing center with respect to the inertia mass body does not change, and
a distance between a center of gravity of the restoring force generation member and the swing center changes in accordance with a change in a swing angle of the restoring force generation member with respect to the inertia mass body.
