PROBLEM TO BE SOLVED: To provide a grill shutter which can prevent the overheating of the inside of an engine room even if there occurs an abnormality that the grill shutter is not manually operated while being left in a closed state.SOLUTION: In a grill shutter 1 which can switch an opening part 4 for taking air into an engine room 3 from a front grill 2 to an opened state that the flow-in of the air into the engine room 3 is easy, and a blocked state that the flow-in of the air into the engine room 3 is suppressed, the grill shutter comprises a rotating mechanism which switches the opened state and the blocked state by rotating shield plates 12, 15 with rotating shafts 13, 16 as centers, and a moving mechanism which is different from the rotating mechanism, and brings the opening part 4 into the opened state by moving the shield plates 12, 15 by a method other than the rotation. When there occurs an abnormality that the rotation mechanism is not operated while the opening part 4 is left in the blocked state, the moving mechanism is operated, and the opening part 4 is brought into the opened state.

    【課題】グリルシャッターが閉じたまま作動しない異常が発生した場合であっても、エンジンルーム内の過熱を防止することができるグリルシャッターを提供すること。【解決手段】フロントグリル2からエンジンルーム3内へ空気を取り込むための開口部4を、エンジンルーム3内への空気の流入が容易な開放状態と、エンジンルーム3内への空気の流入が抑制される遮蔽状態とに切り替えることが可能なグリルシャッター1において、遮蔽板12,15を回転軸13,16を中心にして回転させることにより開放状態と遮蔽状態とを切り替える回転機構、および、回転機構とは異なる機構であって遮蔽板12,15を前記の回転以外の方法で移動させることにより開口部4を開放状態にする移動機構を設け、開口部4が遮蔽状態のままで回転機構が作動しない閉異常が発生した場合に、移動機構を作動させて開口部4を開放状態にする。【選択図】図2
