Abstract
A commutator comprises a plurality of commutator segments on the outer circumferential surface and is connected at one end to an armature. At the other end, the commutator has an annular noise-preventing electric element, such as varistor, which has a plurality of connecting electrodes, each of which is electrically connected to each of the commutator segments via a short-circuit conductor, thereby avoiding soldering connection.
