A grille shutter device includes a grille shutter configured to change its opening degree and placed in a grille opening continuous with an engine room of a vehicle. An ECU controls a motor to control an opening degree of the grille shutter to regulate running air from the grille opening to an engine. The running air passing through the grille shutter flows to a lower part of the cylinder block. The ECU controls the motor to control the opening degree of the grille shutter according to a detected temperature of the lower part of the cylinder block by a temperature sensor. When judging that warm-up of the lower part of the cylinder block is not yet completed, the ECU controls the motor to close the grille shutter in order to block the running air flow from the grille opening to the lower part of the cylinder block
