PROBLEM TO BE SOLVED: To provide a throttle control device of an internal combustion engine capable of preventing ingress of wear debris generated by slides between parts and wear debris generated by vibrations between parts caused by the engine, preventing defective contact between a brush of a throttle sensor and a substrate, and detecting correct throttle opening. SOLUTION: A brush 18a of a sensor part 22 is fixed to an outer end part of a throttle shaft 2 protruded from a cover 15, and the sensor part 22 is stored in a sensor chamber 24 formed on the outer side of the cover 15. A gear chamber 23 to store gears is isolated from the sensor chamber 24 via a dust seal 17. Wear debris does not enter the sensor chamber 24, but is deposited between the brush 18a and a sensor substrate 19. Therefore, no defective contact occurs, and the detection capacity of the sensor is not degraded. COPYRIGHT: (C)2004,JPO&NCIPI
