A throttle device comprising:
- a throttle shaft to which a throttle valve is secured;
- a motor;
- and
- a decelerator including a gear secured to the throttle shaft, decelerating rotation of a drive shaft of the motor, and transmitting the rotation to the throttle shaft,
- wherein the gear includes a tubular ring member into which the throttle shaft is detachably inserted and a gear main body including a gear portion,
- the tubular ring member having a cylindrical shape and being formed of metal, the tubular ring member having a shaft hole through which the throttle shaft passes at the shaft center and a securing hole passing through the throttle shaft center for inserting a pin that passes through the shaft center and extends in the radial direction,
- the gear is formed by resin,
- the gear main body is formed by insert processing including the ring member, and
- the throttle shaft and the gear including the tubular ring member formed by the insert process, are removably fixed to the gear and the throttle shaft by inserting the pin into the securing hole in the tubular ring member.
