ABSTRACT:
An air intake control system includes valve elements disposed in intake passages for varying the cross-sectional area of each intake passage, a valve shaft for transmitting a driving force to the valve element, an actuator including a motor for producing the driving force for turning valve shaft, a worm gear mounted on a rotary shaft of the motor, and a housing accommodating the motor and the worm gear, and a driving gear which meshes with the worm gear to transmit the driving force supplied from the actuator to the valve shaft. The driving gear includes a boss portion, a tooth portion which meshes with the worm gear, and an elastic member which is sandwiched between and bonded to the boss portion and the tooth portion. The boss portion rotates together with the valve shaft, whereas the tooth portion and the elastic member can rotate relative to the valve shaft.
