GRILLE SHUTTER DEVICE

To flow air to a specific heat exchanger preferentially in a structure where multiple heat exchangers are provided.SOLUTION: A grille shutter device 10 includes a first opening 12 which is provided between a grille 34 and multiple heat exchangers (a first heat exchanger 26, a second heat exchanger 28, and a third heat exchanger 30) and through which air introduced from the grille 34 passes. Further, the grille shutter device 10 includes a second opening 14 which is provided independently from the first opening 12, allows air from the vehicle front to pass therethrough, and guides the air that has passed therethrough to the predetermined heat exchanger (the third heat exchanger 30) side. Further, the grille shutter device 10 includes grille shutters 20 which are operated to open or close the first opening 12 and brought to a predetermined posture different from states that the grille shutters 20 close and open the first opening 12 to guide the air that has passed through the first opening 12 to the predetermined heat exchanger (the third heat exchanger 30) side.SELECTED DRAWING: Figure 4 【課題】複数の熱交換器が設けられた構成において特定の熱交換器へ優先的に空気を流す。【解決手段】グリルシャッタ装置１０は、グリル３４と複数の熱交換器（第１熱交換器２６、第２熱交換器２８及び第３熱交換器３０）との間に設けられ、グリル３４から導入された空気が通過する第１開口部１２を備えている。また、グリルシャッタ装置１０は、第１開口部１２とは独立して設けられ、車両前方側からの空気が通過し、通過した空気を所定の熱交換器（第３熱交換器３０）側へガイドする第２開口部１４を備えている。さらに、グリルシャッタ装置１０は、作動されることで第１開口部１２を開閉し、第１開口部１２を閉止している状態及び開放している状態とは異なる所定の姿勢とされることで第１開口部１２を通過した空気を所定の熱交換器（第３熱交換器３０）側へ案内するグリルシャッタ２０を備えている。【選択図】図４
