An electric motor is provided with especially brushes of which rear ends are cut diagonally to form acute angles at the corner edges on the backward side of the rotating direction of the armature. The brushes are maintained securely in brush holders without vibration by first and second side walls of the brush holders according to component force of pressing force applied on the slant rear ends of the brushes by pressing members, therefore the objectionable noise caused by the "stick-slip" is prevented very effectively without introducing complicated structure in the motor.
