VIBRATION DAMPING STRUCTURE

摘要

Provided is a vibration damping structure capable of obtaining a sufficient vibration damping effect even for vibrations with small amplitude by promoting the movement of powder/grain materials in a hollow body. The vibration damping structure, wherein a vibration damping member (2) is provided to a structure (1) serving as an object to be vibration-damped. The vibration damping member (2) is configured by a hollow body (5), powder/grain materials (3) which are filled in 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 is mounted in the hollow body (5) so as to vibrate relatively to the hollow body (5). The vibrator (6) comes into contact with the powder/grain materials (3) to exert a force thereupon at the time of vibration.
