Abstract: A reduction drive-side mounting end face on a strain wave gearing reduction drive unit has a circular center hole, and a motor-side mounting end face on a motor has a circular projection. The strain wave gearing reduction drive unit and motor are coaxially mounted by the circular projection being fit into the circular center hole with a regulating ring therebetween. The regulating ring, which regulates the motion of a flexible external gear, can be easily mounted to the strain wave gearing reduction drive unit by using the motor. The strain wave gearing reduction drive unit can be mounted to a motor comprising a circular projection with a different outer diameter by using a regulating ring with a different inner diameter.
