PURPOSE: An air control valve in a throttle body is provided to improve the performance of response and acceleration by divisionally forming a throttle valve and quickly controlling the inflow of the outside air. CONSTITUTION: A venturi pipe has a plurality of hinge holes(11,12,13). A plurality of valves(20,20a) are integrated with a square shaft(22) and a cylindrical shaft(23) on both side of a vertical bending part(21) formed on one side of the valve. The end of the square shaft is integrated with a fixing groove(22-1) and hole(22-2), and is inserted into the hinge hole. A plurality of stud gears(30a) have a coupling hole(30-1) inserted into the square shaft. A ring stopper(50) for preventing the stud gear from coming out is inserted into the fixing groove. A rack gear(60) has threads(60a,60b) on both side to engage with the stud gear, and is integrated with a tapped hole(60c) and a fixing part(60d) for fixing a return spring(80). A connecting member(70) connected to an accelerator cable is inserted into the tapped hole.
