Abstract

PURPOSE: To suppress split vibration to obtain a superior vibration preventing effect and improve tone quality by mixing a gelled material into a turntable main body.
CONSTITUTION: A nonmagnetic metal, for example, aluminum, copper or their alloy powder is sintered to form turntable main body 1 including many narrow holes. This main body 1 is soaked in viscoelastic polymer 3 in airtight vessel 2, and after that, air in vessel 2 is exhausted, and foams of main body 1 are removed, and polymer 3 is filled up in narrow holes of turntable 1. Next, main body 1 charged with polymer 3 is hardened at a normal temperature or is stored in heating unit 4 and is heated to perform gelling reaction dependent upon a catalyst, and gelled polymer is charged in narrow holes. As a result, split vibration can be suppressed to obtain a superior vibration preventing effect and improve a tone quality.
