摘要： Provided is a vibration generating stepping motor, which is ensured for holding a stop position by increasing a detent torque. The pole teeth of one stator yoke of a single-phase stator yoke assembly includes two kinds of pole teeth made different in the outermost side faces in the radial direction, and the pole teeth of the other stator yoke are comprised of two kinds of pole teeth made different in the outermost side faces in the radial direction. The pole teeth of one kind of the aforementioned individual stator yokes are made to have the same shape. The pole teeth of the remaining two kinds not given the same shape are combined and arranged to increase the detent torque.
