Summary:The invention relates to a DC machine, especially a DC motor (10) for use in a motor vehicle, comprising a stator (18), a rotor (20) that is rotatably mounted within a field frame (12) and is provided with a commutator (24), and a brush rocker (28) which is essentially made of plastic and is used for supporting at least two brushes (26) and other components (30, 31; 32). According to the invention, the brush rocker has means for improving the position of the components that are arranged thereon relative to the rest of the machine and/or shortening the tolerance chain of the machine (10), in particular also the whole arrangement being stabilized in the long term. La invención se refiere a una máquina de corriente directa, en especial un motor de corriente directa (10) para usarse en un vehículo, con un estator (16), un rotor (29) sostenido rotatoriamente en un alojamiento de estator (12) con un conmutador (24) y con un portador de escobilla (28) producido esencialmente de plástico, para sostener cuando menos dos escobillas (26) y otros componentes (30, 31, 32). De acuerdo con la invención el portador de escobilla (28) presenta medios para mejorar la colocación de los componentes en relación al resto de la máquina y/o para acortar la cadena de tolerancia de la máquina (10), con lo cual se obtiene una estabilización a largo plazo de todo el dispositivo.
