DAMPING STRUCTURE
First Claim
1. A damping structure comprising a damping member which is provided on a structure to be damped, wherein the damping member is composed of:
- a hollow body;
a powder/particle material which is filled in the hollow body with partially leaving a space, and moves inside the hollow body when the structure to be damped vibrates; and
a vibrator which is mounted to the hollow body, and relatively vibrates with respect to the hollow body to come into contact with the powder/particle material to exert a force when the structure to be damped vibrates.

Abstract
The present invention provides a damping structure capable of obtaining a sufficient damping effect even against vibrations with small amplitudes, by promoting movements of powder/particle materials in a hollow body. In the damping structure of the invention, a damping member 2 is provided on a structure 1 to be damped. The damping member 2 is composed of a hollow body 5, a powder/particle material 3 which is filled in the hollow body 5 with partially leaving a space 4, and moves inside the hollow body 5 when the structure 1 vibrates, and a vibrator 6 which is mounted inside the hollow body 5, and relatively vibrates with respect to the hollow body 5. The vibrator 6 exerts a force by coming into contact with the powder/particle material, when vibrating.
