  • Patent number: 7278623
    Abstract: A vibration control unit in which a rolling element having a first curved surface that is a convex surface is interposed between a first and second members, and the rolling element is allowed rolling with respect to the first member in the first curved surface thereof. The rolling element has a second curved surface that faces the first curved surface and is formed of a curved surface center different from that of the first curved surface. As the rolling element, resulting from an additional force applied on the first and second curved surfaces, rolls with respect to the first member, the second member vibrates with a restoring force determined based on an average curvature radius of the first and second curved surfaces of the rolling element and a distance between curved surface centers of the first and second curved surfaces.
