To prolong the life of a vibrating motor, and to cause it to generate favorable vibrational sounds.
In this vibrational motor, a shaft 3 is fixed to one end of its body 2, and a rotor which is a flat-type coreless eccentrically-vibrating armature 4-1 which rotates eccentrically and is supported freely rotatably is made to face its surface opposite to field magnets 1 with an axial gap between, and a commutator 9 connected electrically to an armature coil, constituting the flat-type coreless eccentrically vibrating armature 4-1, is provided so as to be freely slidable on brushes 8-1, 8-2. At this time, the flat-type coreless eccentrically vibrating armature 4-1 is molded with plastic, and the axial end surface of a projection 26 formed by projecting the plastic on the peripheral part of the shaft 3 in the direction of the other end of the motor body 2 is slid and brought into contact with the other end side of the motor body 2, and is used as a thrust bearing.
