Patent ID: 6991077

Claim:
A vibration-damping device for damping vibrations excited in a vibrative member, comprising: a damper mass including a housing member defining a hollow accommodation space therein, and an independent mass member including an elastic member attached thereto being housed within said accommodation space of said housing member with a slight spacing therebetween so that said independent mass member is independent of said housing member and is freely displaceable within said accommodation space of said housing member to come into impact on said housing member via said elastic member; and a metallic spring member adapted to be fixed at a plurality of fixing portions thereof on the vibrative member for elastically supporting said damper mass on the vibrative member, such that said housing member of said damper mass is fixed to a portion of said metallic spring member through which a principal elastic axis of said metallic spring member extends, and that a center of gravity of said damper mass is located approximately on said principal elastic axis of said metallic spring member, so that the metallic spring member elastically connects the housing member to the vibrative member.
