Abstract

PURPOSE:To suppress inherent vibration of a resin or cement bed-like solid body by thickening a portion of said body or enclosing material such as reinforcing steel or resin having different density in said body, and reduce transfer of the external vibration by supporting the bed with an elastic means. CONSTITUTION:A frame 2 providing the rear face of a flat bed 1 solidified with gravel and resin and surrounding the periphery of the bed 1 and two ribs 3 to distribute weight heterogeneously are provided. The provision of the rib adds partial weight to reduce inherent vibration in the longitudinal direction of the bed while increasing bending strength of the bed. In this case the bed material solidified with gravel and resin has about 0.03 of attenuation factor of vibration and excellent antivibration performance.
