Abstract
A geared motor comprising an electric motor, a reduction gear having an input connected to a rotational shaft of the electric motor, an output shaft connected to an output stage gear of the reduction gear, which has a coupling member of resilient material attached thereto and a position sensor for detecting a rotational angle position of the output shaft, which has an input shaft connected to the output stage gear through the coupling member wherein the output stage gear has a protrusion imbedded in the coupling member so as to reinforce the coupling member and prevent it from being twisted whereby there occurs no difference between a rotational angle of the output shaft and that of the input shaft of the position sensor.
