Claim 4:
5. An electronically controlled throttle device comprising:
a body including a throttle valve;
a motor provided with a brush, the motor configured to drive the throttle valve;
a bracket configured to attach the motor to the body;
a pigtail connected electrically to the brush, and arranged on a surface of the bracket, the surface facing the motor; and
