Abstract
PURPOSE: To realize the cost reduction for the tone arm without impairing such advantages as the light weight, large rigidity and large Young's modulus/density ratio, by using the composite material of the organic material and the solid powder.
CONSTITUTION: The organic material, such as vinyl chloride PVC, is heated in the nonoxidizing atmosphere to obtain the pitch-type material. This PVC pitch is heated and kneaded with the solid powder like the graphite powder or the like. The kneaded composite material is formed into the desired shape by heating and compression or receives the extrusion molding.
