PROBLEM TO BE SOLVED: To provide a motor provided with a sufficient eccentricity quantity without mounting a weight to the outside of the rotor. SOLUTION: This DC cored type vibration motor has a commutator (10) having two pairs with segment pieces (10a and 10c, 10b and 10d) which rotate integrally with the rotor, are quadrisected and are arranged to face each other as a pair and a pair of power feed brushes (9a and 9b) which feed electricity to a pair of the segment pieces of this commutator. Two phases of windings (17a and 17b) are wound around any one magnetic pole of a rotor core (6) and both ends of one phase of the winding are respectively connected to a pair of the segment pieces of the commutator and both ends of two phases of the windings are respectively connected to another pair of the segment pieces, by which the rotor itself is provided with the sufficient eccentricity quantity.
