Provided is an eccentric oscillation gear device including: a crank shaft having eccentric portions; oscillation gears having insertion holes into which the eccentric portions are inserted; an outer cylinder; and a carrier. The outer cylinder and the carrier concentrically rotate relative to each other by the oscillation of the oscillation gears due to the rotation of the crank shaft. The eccentric oscillation gear device includes a storage unit which stores at least one type of information out of: information on a parameter that originates from a processing error and influences rotation angle characteristics; information on a parameter that changes depending on temperature and influences rotation angle characteristics; and information on a parameter that influences time-dependent change characteristics and influences rotation angle characteristics. |
