An objective of the present invention is to further reduce the total costs of building an eccentric swinging type reducer series. The eccentric swinging type reducer series is configured with a plurality of reducers included in a plurality of frame numbers corresponding to the size of the transfer torque. The reducers (10a, 10b) included in the reducer series include: internal gears (12a, 12b); first external gears and second external gears (14a, 14b, 16a, 16b); a plurality of crank shafts (18a, 18b) provided on a location offset by (L1) from a shaft center (O3) of the inner gear to swing the first external gears and the second external gears; and crank shaft gears (30a, 30b) to transfer power from the input side to the crank shaft, wherein outer splines (24a, 24b) are provided on an end of the crank shaft to couple the crank shaft gear, and the outer spline has a common size and shape between the reducers (10a, 10b) included in different frame numbers (W1, W2). |
