Abstract
PURPOSE:To prevent a turn table from resonating so as to prevent generation of howling and lowering of the reproducibility, by forming a flame sprayed layer of a vibration damping metal onto at least one surface of upper surface and rear surface of the turn table. CONSTITUTION:The upper surface and rear surface of the turn table body 1 approximately in the shape of a disk are formed with the flame sprayed layers 2. The layers 2 is formed by flame spraying such as plasma flame spraying of a vibration damping metal. As damping metals are mentioned a single metal or an alloy whose internal friction Q<-1> is significantly large and inherent damping capacity is significantly large compared with aluminum alloys or the like conventionally used for the turn table body 1: for example, Mg or Ni and Mg-Zr alloy, Mg-Mg2Ni alloy, Ni alloy, Mn-Cu alloy, etc.
