Abstract
Hemispherical protrusions are protrudingly provided in end surfaces of a rotor gear and a tooth portion of a small gear having the smaller number of gear teeth between the rotor gear and a large gear of an intermediate gear, and between the small gear of the intermediate gear and an output gear, which are meshed with each other in a transmission gear train. Thus, in a case where the large gear rides on the rotor gear or the small gear rides on the output gear when the intermediate gear is accommodated in a housing after the rotor gear and the output gear are accommodated, it is possible to cancel the riding state thereof only by applying a slight vibration to the housing.
