Abstract

A brush assembly for a small motor has brushes that are not separated from a commutator when the brushes contact the commutator. The brushes are arranged so that the angles formed by the brushes where the brushes contact the commutator are maintained uniform during assembly of the motor. The pair of brushes include bases connected to each other through a lead frame. The pair of brushes are embedded in a support by molding the support with middle portions of the brushes sandwiched by part of the support so that the angles formed by the pair of brushes where the brushes slidably contact the commutator are uniform.
