PURPOSE: To further reduce the vibration at the time of high-speed operation by arranging a mounting member of a centrifugal bowl/drive motor assembly within a mounting plane orthogonal with a revolving shaft and making the center of gravity thereof in a position proximity to this mounting plane. CONSTITUTION: Three pieces of resilient mounting members 22 are placed on a platform 20 of a supporting structure 12. These resilient mounting members 22 are disposed around the revolving shaft of the centrifugal bowl/drive motor assembly 14 at spaced intervals so as to constitute a symmetrical shape. The center of gravity of the assembly 14 is positioned within the plane of the mounting plane passing a disk member 30. Further, the vibration attenuation structure of the state statically and dynamically balancing each of the parts of the two rotating stages of the centrifugal bowl 52, i.e., the various members rotating at a full speed together with a mandrel 58 and the various members rotating at a half speed together with a housing 62 with respect to the revolving shaft. |
