PURPOSE: A throttle body of automotive vehicle is provided to reduce a noise caused by an air supplied from a bypass channel and achieve an enhanced space efficiency while installing a slip speed control actuator into a throttle body. CONSTITUTION: A throttle body comprising an air supply bypass channel(14) extended from an inlet formed at the throttle body and communicated to a bore(13), and a slip speed control actuator for controlling volume of air supplied from the bypass channel(14), wherein the bypass channel(14) is extended so that the channel(14) circulates around the outer side of the bore(13) and an outlet(16) of the bypass channel(14) is positioned in opposite to the slip speed control actuator, and the outlet(16) of the bypass channel(14) opened toward the bore(13) is extended so that the speed of air flow is reduced while the amount of air flow toward the bore(13) is regulated. Thus, a noise caused by an air supplied via the bypass channel(14) is reduced.
