An electronic throttle body unit of an automobile is provided to prevent the engine suddenly from being put out because the carbon accumulated in the throttle lever is removed using the vortex of the air. An electronic throttle body unit(1) of an automobile comprises a throttle body(10) in which the air inhalation flow way(15) is formed, a throttle lever(20) which is possible to rotate, is installed on the air inhalation flow way around the hinge shaft(25), a motor(30) which is installed at the Throttle Body and operates the hinge shaft, a position sensor(35) sensing the open angle of the throttle lever, a vortex generating unit(50) formed in the front of throttle lever, and a controller(40) determining as the high speed operation region and controls the eddy generator so that vortex is generated.
