Abstract
A vibrating motor has a shaft, a stator including a yoke having pole teeth extending toward an axis of the shaft from an inner circumference and coils wound around the pole teeth, a rotor including an eccentric weight formed on a radially outer surface of the shaft, and a permanent magnet integrally formed with the eccentric weight, and a bearing device rotatably supporting the rotor maintaining clearance between the inner circumference of the pole teeth and the rotor. The rotor has a structure in which the shaft, the eccentric weight, and the permanent magnet are integrally formed with each other by a thermoplastic magnetic material composing the permanent magnet.
