Claims

[Scope of utility model registration request]

In a vibration damping device that is provided between a vibrating body serving as a vibration source and a vibrating body to which vibrations are transmitted from the vibrating body, and includes an elastic body that is elastically deformed by vibration input from the vibrating body. A fluid dynamic damper is formed by forming a first fluid and a second fluid chamber inside the elastic body, communicating the two fluid chambers through a communication passage, and sealing fluid in both the fluid chambers and the communication passage. What is claimed is: 1. A vibration damping device comprising: a resonant weight body movable within the communication path;
