ABSTRACT:
A stepping motor is equipped with a rotor, a supporting member that rotatably support the rotor, and stators that have multiple stator teeth and that face each other across the diameter of the rotor, wherein said multiple stator teeth are positioned such that they are apart from each other. Using the construction described above, it is possible to make the rotor diameter smaller than the conventional model, thereby reducing the overall size of the stepping motor. Therefore, it is possible to make the outer diameter of lens barrel smaller than the conventional model without changing the lens diameter, which in turn makes the overall size of the camera more compact.
