ABSTRACT:
A vibration-damping device for damping vibrations of a vibrative member, which includes a damper mass member having a rigid abutting portion, a spring member for elastically connecting the damper mass member to the vibrative member to cooperate with the damper mass member to constitute a second vibration system whose natural frequency is tuned to a frequency band of the vibrations of the vibrative member, and an independent mass member disposed so as to be opposed to the rigid abutting portion in a vibration input direction with a given gap therebetween without being adhesive to the rigid abutting portion. The independent mass member is independently displaceable relative to and brought into abutting contact directly and elastically with said rigid abutting portion in said vibration input direction.
