PURPOSE: A wind noise reduction apparatus of a front pillar for a vehicle is provided to decrease vortex from Coanda effect by injecting z-flow to the surface of a window glass from a nozzle with a blower, and to minimize wind noise by forming the film layer evenly in the surface of the window glass. CONSTITUTION: A wind noise reducing device of a front pillar(1) for a vehicle is composed of an air duct(3) installed longitudinally in the front pillar; a hose(4) connected to the lower part of the air duct; a blower(5) supplying air through the hose to the air duct; and a nozzle(6) installed in the air duct to inject z-flow to a window glass(2). Air is supplied to the air duct through the hose with the blower, and injected to the window glass through the nozzle at high speed. Wind noise is reduced by separating vortex from the window glass with z-flow and adding to main flow.
