Rotation stabilizing device in a microgravitational rotating apparatus

A rotation stabilizing device in a microgravitational rotating apparatus, wherein:

• said microgravitational rotating apparatus comprises a casing, a rotary shaft provided within said casing and having two ends that are both supported by bearings so as to be rotationally driven by a motor, and a plurality of radially extending arms having first ends fitted and supported to said rotary shaft and other ends fitted with a plurality of boxes for having objects having weight placed therein;
• and
• a vibration isolating device for stabilizing rotation provided between an outer side of said casing and stationary structure, said vibration isolating device supporting said casing at each of a plurality of places on an outer peripheral portion of said casing and comprising:
• a spring mechanism elastically supporting said casing on said stationary structure, and
• an electromagnetically supporting mechanism comprising an excitation coil connected to said spring mechanism so as to electromagnetically support said spring mechanism with respect to said stationary structure by excitation of said excitation coil;
• wherein said spring mechanism comprises one or more selected from the group consisting of bar-like rod springs, bar-like coil springs, and members made of rubber, plastics, etc. having a predetermined elasticity.
