Abstract: There is provided a small-sized and slim driving device which is easy to manufacture and capable of producing high output. A magnet has a cylindrical shape, and at least the outer peripheral surface of the magnet is circumferentially divided into n sections magnetized so as to have alternately different poles. The magnet can rotate about a rotational axis of the cylindrical shape. A coil is arranged axially of the magnet and parallel thereto. An outer magnetic pole portion is disposed to be magnetized by the coil, and has a plurality of hair comb tooth-shaped portions opposed to the magnet and arranged around the magnet such that an angle corresponding to the circumferential width of each of the hair comb tooth-shaped portions opposed to the magnet about the rotational axis of the hollow cylindrical shape of the magnet is equal to a predetermined angle A. An inner magnetic pole portion is disposed to be magnetized by the coil, and has a hollow cylindrical shape opposed to the inner peripheral surface of the magnet. The predetermined angle A is set to such a value that a rotational force acts on the magnet to return to a position in which a circumferential center of each of n magnetized sections on the outer peripheral surface of the magnet is opposed to a circumferential center of a corresponding one of the hair comb tooth-shaped portions of the outer magnetic pole portion, when the circumferential center of each of n magnetized sections shifts from the position.
