Even though the output shaft of the prime mover is directly used as the sun shaft of the planetary roller reducer, both ends of the output shaft of the prime mover are supported by the housing via rolling bearings. It is pointed out that with such a structure, it is extremely difficult to precisely control the coaxiality between the axis of the planetary roller reducer and the axis of the rolling bearing on the planetary roller reducer side. That is, the above-mentioned coaxiality is determined by the relative relationship between the mounting accuracy of the rolling bearing with respect to the housing and the mounting accuracy with respect to the housing of the planetary roller reducer, but it is not only extremely difficult to manage these, High cost is forced.
