PURPOSE: A throttle body for a vehicle is provided to uniformly maintain the inflow of air by preventing the deposition of oil and carbon in the blow-by gas flowed through a bypass passage. CONSTITUTION: In a throttle body(110) for a vehicle, an air tube(114) is formed within a housing(112). A valve(116) is fixed on the center of the air tube by a hinge. A bypass passage(10) includes a first passage and a third passage to bypass air in the front and rear of the valve, and a second passage connected to the first passage and the third passage. An inflow preventing protrusion(12) formed on the one side of the air tube. A first carbon removing groove(13) is formed on the first passage. A second carbon removing groove(14) is formed on the end portion the second passage.
