摘要： A method of adjusting a drive mechanism includes measuring backlashes between the ring gear and the plurality of drive devices, and determining about positions of the plurality of drive devices with reference to the ring gear based on the backlashes measured in the measurement step. The measurement step includes: aligning the pinion of one of the plurality of drive devices to face a reference position in a circumferential direction of the ring gear and measuring a backlash between the ring gear and the said one drive device; and aligning the pinion of another one of the plurality of drive devices to face the reference position of the ring gear by revolving the plurality of the drive devices relative to the ring gear, and measuring a backlash between the ring gear and the said another drive device different from the said one drive device whose backlash has been measured.
