摘要:
In a chucking device, a rolling guide portion is arranged below an upper cover portion of a rotor holder and radially inwards of a cylinder portion of the rotor holder. This helps restrain the noises generated by the rolling movement of balls from propagating to the outside. Moreover, the turntable and the rolling guide portion are formed of a single resin member extending continuously through a through-hole defined in the rotor holder.
