Abstract: A geared motor is provided. A through hole formed in a base passes a rotor shaft. An annular guide rim to guide a carrier and a cylindrical stationary gear are integrally and concentrically formed on the base which seals an open end of a small motor. A guide to guide the rotation of a movable gear is provided at the top end of the stationary gear. The gears making up the geared motor are disposed in a compact arrangement with high accuracy.
