A low-cost, small-sized and high-output driving device which makes it possible to produce two outputs separately and is easy to handle. The driving device has two driving units comprised of a coil, a stator, a magnet, and a rotor. The two driving units are arranged, side by side, along the axis of the driving device. In particular, a portion of the first rotor of one driving unit inserted in an inner periphery of the second coil of the other driving unit and the inner periphery of the second rotor of the other driving unit. The portion of the first rotor is magnetized by the second coil.
