PURPOSE:To enable a power shaft rod to be positioned at an optional position, by generating electromagnetic action respectively between a rotary unit and a substrate, and between the rotary unit and the power shaft rod. CONSTITUTION:By electromagnetic action between a magnetic field forming unit 16 and a coil 18 which are provided respectively for a rotary unit 1 and a substrate 5, the rotary unit 1 is rotated to the substrate 5. By electromagnetic action between a coil 19 and a magnetic field forming unit 17 which are provided respectively for the rotary unit 1 and a power shaft rod 11, the power shaft rod 11 is rotated around a shaft to meet at right angles to a shaft rotating to the rotary unit 1. As the result, the power shaft rod 11 is rotated around two shafts meeting at right angles to each other. |
