Abstract
A miniature motor having brushgear comprising brush arms with sliding parts on the tips thereof, terminals and brush bases; the brush bases being supported by a motor case cover plate, when the terminals are inserted in brush holes provided on the motor case cover plate; the sliding parts being brought into sliding contact with a commutator by the resiliency thereof, and characterized in that a flexible photo-setting resin having similar resiliency to the resiliency of vibration-damping rubber is applied to the brush arms to prevent the brushes from unwantedly vibrating during rotation of the commutator.
