PURPOSE: A variable radiator grille is provided to adjust the opening area of the radiator grille according to driving conditions of an engine. CONSTITUTION: In a variable radiator grille(20), plural grille plates are formed in the longitudinal direction of a case(21) to guide the external air to an engine room. The variable radiator grille comprises grille plates(22), pinion gears(30), a rack gear(40), and a reversible motor(50). Pivots(23,24) projected to the ends of the grille plate are axially combined to the sides of the inside of the case. The pinion gear is axially combined in the middle of one side of the pivots of each grille plate. The pinion gears are arranged parallel in the horizontal direction. Both ends of the rack gear are combined to the upper and lower sides of the case. Each pinion gear is simultaneously engaged with the rack gear. The reversible motor operates the rack gear to rotate the grille plates according to the driving conditions of an engine.
