Summary:PROBLEM TO BE SOLVED: To provide a vibration damping structure capable of obtaining a sufficient vibration damping effect even for vibrations with small amplitudes by promoting the movement of powder/grain materials in a hollow body. SOLUTION: The vibration damping structure includes a vibration damping member 2 in a structure 1 serving as an object to be vibration-damped. The vibration damping member 2 includes: a hollow body 5; powder/grain materials 3, which fill the hollow body 5 with a space 4 partially left in the upper part and which move in the hollow body 5 when the structure 1 vibrates; and a vibrator 6, which, mounted in the hollow body 5 so as to exert a force in contact with the powder/grain materials 3 at vibration, vibrates relatively to the hollow body 5.
