Vibration-damping device

A vibration-damping device for damping vibrations of a vibrative member that is a primary vibration system having a first spring component and a first mass component, comprising:

• a damper mass member having a second mass component with a rigid abutting portion;
• a spring member having a second spring component separate from the first spring component, and elastically connecting said damper mass member to the vibrative member for elastically supporting said damper mass member on the vibrative member, and cooperating with said 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 said rigid abutting portion in a vibration input direction with a given gap therebetween without being adhesive to said rigid abutting portion, and being independently displaceable in relation to said rigid abutting portion to come into abutting contact directly and elastically with said rigid abutting portion in said vibration input direction.
