Abstract
An electric motorand a worm gearwere housed in a case, an output shaftof the electric motorand a fitting holeC of the worm gearwere fitted so as to be capable of freely transmitting torque and of freely moving relatively in a direction of an axis X, and a tip of the output shaftand an inner end of the fitting holeC set a gap D of separation in the direction of the axis X. Furthermore, a support sectionmaking contact with an end section of a shaft sectionA of the worm gearat the side of the electric motorthereof was provided inside the case, and a thrust force resulting from dynamic inertia of the wheel gearupon stopping of the electric motorand acting on the worm gearwas borne by the support section
