Eccentric commutator for vibrator motor

摘要

A compact flat type vibrator motor is provided in which movement of the center is secured in the commutator itself, an additional eccentric member does not need to be provided, and the number of parts are reduced, so that mass production is possible. The commutator pieces are located in a commutator base member including a printed wiring board having a portion to which a high density resin of a specific gravity of 3 or more is added. A shaft receiving portion is centrally located in the commutator base member. The high density resin portion is eccentric so that an eccentric rotor is formed.
