ABSTRACT:
This invention is intended to provide a vibration damping device having a high degree of freedom of design of damping performance. This device includes rolling bodies (4) interposed between an upper structure (1) and a lower structure (2) to horizontally swingably support the upper structure (1) and elastomeric members (5) disposed between the rolling bodies (4) and the upper and lower structures (1, 2). In this device, rolling surfaces for the rolling bodies (4) are formed by elastomeric members (5) and rigid members (6). For example, the elastomeric and rigid members (5, 6) are disposed respectively in association with the opposite end regions and central regions of the rolling bodies (4). The elastomeric members (5) may be made of any desired material provided that it has viscoelasticty and the rigid member 6 may be made of any desired material provided that the rolling friction of the rolling bodies (4) thereon differs from that on the elastomeric members (5). For example, metal, ceramic material, rigid plastic material, FRP, FRM, and PTFE are preferable.
