Disclosed is a rotation mechanism for automobile radiator grilles (20) to reduce air resistance and maintain constant air flow. Rotating shafts(24) that are inserted into housing(22) are installed in the upper and lower center of individual grilles(20); each radiator grille(20) is connected by a connection link(30) with a rack gear(32); the pinion gear(42) of grille rotating motor(40) is geared to rack gear(32); and car turn angle arithmetic controller(60) and rotary encoder(56) are connected to steering wheel(50) and grille(20) rotating motor(40). Connection link(30) has a thin elastic neck(30a) and a pre-compressed spring that compresses rack gear(32) is fitted so that connection link(30) follows radiator grille(20) and does not deviate from pinion gear(42). The invention minimizes air resistance and increases fuel consumption.
