1. A microgravitational rotating apparatus comprising:

  • a casing;

    a rotator including;

    a rotary shaft within said casing;

    a plurality of arms, each of said arms extending in a radial direction of said rotary shaft and having a first end fitted to a circumferential periphery of said rotary shaft; and

    a plurality of boxes, each of said boxes being fitted to a second end of a respective one of said arms, each of said boxes holding a gravitational or gravity-adding object;

    a motor for rotationally driving said rotary shaft; and

    a rotator supporting mechanism comprising;

    a bearing supporting at least one end of said rotary shaft so as to maintain said rotary shaft at a position by a position-holding force provided by said bearing; and

    a control unit operable to control the position-holding force of said bearing to thereby control vibration of said rotary shaft so as to generate no reaction force.
