Abstract

PROBLEM TO BE SOLVED: To prevent resin gears from seizing by doing away with backlash of an axis direction of an intermediate gear or a gear at final reduction stage, reducing abrasion of a gear caused by engine vibration, and improving the accuracy of a throttle valve opening control. SOLUTION: A motor 1 rotates by a signal from CPU. Rotation of the motor 1 is transmitted from a pinion 2 of an output shaft of the motor 1 to an intermediate gear of a countershaft 3. The intermediate gear is composed of a wheel 4 engaging in the pinion 2, and a pinion 5, which is energized to left by a spring washer 15 so as to do away with axis direction backlash. Rotation of the pinion 5 is transmitted to a wheel 7 of a throttle shaft 6. A spring washer 20 energizes the throttle shaft 6 to left so as to do away with the axis direction backlash of the wheel 7. Each pinion and each wheel is made of a resin and engages in a glassed 66 nylon and an aromatic nylon. Power of the spring washer 20 is stronger than that of the spring washer 15.
