Abstract
In a vibration damping device, a main rubber elastic body has a truncated cone shape and includes a recess open to a lower surface. A central axis of an inner member is arranged eccentric with respect to a central axis of an outer cylindrical member in an axis-perpendicular direction. The main rubber elastic body that connects the inner member and the outer cylindrical member has different free lengths on one side and the other side in an eccentric direction. A continuous rubber that covers a lower end of the inner member without exposing the lower end of the inner member to the recess and connects the main rubber elastic body on one side in the eccentric direction and the main rubber elastic body on the other side in the eccentric direction is integrally formed with the main rubber elastic body.
