<p>A rubber sheet for a turntable, which comprises a sheet-shaped, cured molding of a rubber composition, and which has a rubber hardness of a specific range (30 or less on a hardness meter described in JIS K6301-1969 and 15 or more on a hardness meter of model Asker F made by Kobunshi Keiki K.K.) and an impact resistance ratio of 40% or more, to prevent a deterioration in the quality of reproduced sound due to howling or outside vibration. Many projections (3) are provided on one side of a rubber sheet (1), which are formed so that they come into linear or point contact with a turntable or record disk to insulate the disk from outside vibration by an air layer formed between the turntable or record disk and the rubber sheet body (1). </p> |
