PURPOSE: A throttle body for a vehicle is provided to properly control acceleration by adjusting intake air amount according to low/medium/high speed. CONSTITUTION: On the each side of a throttle body(10), a first duct(30) is connected to a first air cleaner(20) and a second duct(60) is connected to a second air cleaner(50). A first valve and a second valve are installed within the first duct and the second duct respectively. A winding wheel(80) is rotated by the driving of an actuator(90), and selectively opens/shuts the first valve or the second valve. The winding wheel opens/shuts only the first valve in a low/medium speed section, and opens/shuts the first valve and the second valve in a medium/high speed section.
