Abstract
A throttle control apparatus for an internal combustion engine in which wear particles due to sliding between components and vibration wear particles produced between components by engine vibrations are prevented from entering the area between a brush of a throttle sensor and a sensor substrate to prevent the occurrence of a contact failure between the brush and the substrate, thereby making it possible to detect an accurate throttle opening. A brush of a sensor unit is secured to an outer end portion of a throttle shaft projecting from a cover, and the sensor unit is accommodated in a sensor chamber formed outside the cover. A gear chamber for accommodating gears and the sensor chamber are isolated from each other by a dust seal. Therefore, wear particles will not enter the sensor chamber and accumulate in the area between the brush and the sensor substrate to cause a contact failure.
