After the rotor gripping device 312 grips the rotor, it first rotates from the vertical direction to the horizontal direction. After completion, the entire rotor conveying mechanism 30 is lifted by the mechanism adjusting unit 320. Then, the rotor is driven by the braking unit 308 to reach above the rotor precision turning carrier 3. At this time, the mechanism adjusting unit 320 moves the entire rotor conveying mechanism 30 downward, so that the rotor enters the rotor precision turning carrier 3. At this time, the rotor gripping device 312 is rotated from the horizontal direction to the vertical direction, thereby realizing placing the rotor on the rotor precision turning carrier 3.
