Abstract
A vibration damping device includes a support member that rotates, together with a rotary element to which torque from an engine is transmitted, about a center of rotation of the rotary element, a restoring force generation member that is coupled to the support member to transmit torque to and receive torque from the support member and that is swingable along with rotation of the support member, and an inertial mass body that is coupled to the support member via the restoring force generation member and that swings about the center of rotation in conjunction with the restoring force generation member along with rotation of the support member. The support member is disposed between at least a part of the restoring force generation member and at least a part of the inertial mass body in an axial direction.
