Abstract:
A vibration damping device capable of maintaining high vibration damping effect, and a bucket for a construction machine. The vibration damping device has a laminated plate (20) having at least its inner region fixed in a noise-emitting base material (11), the inner region being a region (G) other then a region which becomes a loop in a vibration mode when the base material (11) is vibrated in a vibration mode with a predetermined frequency.
