- integrally and simultaneously forming said brushes and connectors partially connected by electrical link portions from a unitary conductive material;
- integrally fixing together said connectors by an insulating resin;
- cutting only unnecessary link portions of said electrical link portions so as to form a desired electric circuit having at least one link portion between said connectors after fixing said connectors by said insulating resin; and
- mounting said connectors in said housing after cutting said unnecessary link portions of said electrical link portions.
- 4. A method of manufacturing a motor actuator having an output gearwheel rotated by a motor, a pattern conductor provided on one side of said output gearwheel, a plurality of brushes contacting said pattern conductor, a plurality of connectors corresponding to respective of said brushes, a housing containing said connectors, and said connectors electrically connecting said brushes to electrical components, wherein said insulating resin fixes said connectors and forms a connecting portion which connects with an external plug, said method comprising the steps of:
- integrally and simultaneously forming said brushes and connectors partially connected by electrical link portions from a unitary conductive material;
- integrally fixing together said connectors by an insulating resin so as to form a fixing portion and a connecting portion;
- cutting only unnecessary link portions of said electrical link portions so as to form a desired electric circuit having at least one link portion between said connectors after fixing said connectors by said insulating resin; and
- mounting said connectors in said housing after cutting said unnecessary link portions of said electrical link portions.
- 5. A method of manufacturing a motor actuator having an output gearwheel rotated by a motor, a pattern conductor provided on one side of said output gearwheel, a plurality of brushes contacting said pattern conductor, a plurality of connectors corresponding to respective of said brushes, a housing containing said connectors, and said connectors electrically connecting said brushes to any electrical components, wherein said pattern conductor comprises a conducting portion formed circumferentially around an axis of said output gearwheel, and an insulating portion insulating said conducting portion, wherein said conducting portion and insulating portion are concentric with said axis and offset by a predetermined angle, wherein at least one of said brushes avoids said insulating portion and conducts with said conducting portion, and at least one of said brushes slides on said pattern conductor in a circumferential direction, and wherein said insulating resin fixes said connectors and forms a connecting portion which connects with an external plug, said method comprising the steps of:
- integrally and simultaneously forming said brushes and connectors partially connected by electrical link portions from a unitary conductive material;
- integrally fixing together said connectors by an insulating resin so as to form a fixing portion and a connecting portion;
- cutting only unnecessary link portions of said electrical link portions so as to form a desired electric circuit having at least one link portion between said connectors after fixing said connectors by said insulating resin; and
- mounting said connectors in said housing after cutting said unnecessary link portions of said electrical link portions.
- 6. A method of manufacturing a motor actuator having an output gearwheel rotated by a motor, a pattern conductor provided on one side of said output gearwheel, a plurality of brushes contacting said pattern conductor, a plurality of connectors corresponding to respective of said brushes, a housing containing said connectors, and said connectors electrically connecting said brushes to electrical components, wherein said pattern conductor comprises a resistor portion having a predetermined resistivity and formed in an arc around an axis of said output gearwheel, and a conducting portion electrically connected to one end of said resistor portion, wherein at least one of said brushes contacts and conducts with said conducting portion, and at least one of said brushes contacts and conducts with said resistor portion, and wherein said insulating resin fixes said connectors and forms a connecting portion which connects with an external plug, said method comprising the steps of:
