ABSTRACT:
A vibration damper including: a mounting member secured to a subject body; a first mass member which is displaceable relative to the mounting member in a direction of an input vibration of the subject body; a first elastic member elastically connecting the first mass member to the mounting member; a second mass member which is displaceable relative to the mounting member and the first mass member in the direction of the input vibration of the subject body; a second elastic member elastically connecting the second mass member to the first mass member; a member for generating an oscillating force as a force of relative displacement between the first mass member and the second mass member in the direction of the input vibration of the subject body; and a fluid chamber filled with a non-compressible fluid, the fluid chamber being partially defined by the first elastic body and the second elastic body and disposed between the mounting member and the second mass member.
