PROBLEM TO BE SOLVED: To provide a grille shutter device capable of preventing an opening/closing member from moving to a closing direction side from a half-opened position.SOLUTION: A grille shutter device 10 comprises: a movable fin 11 which is provided inside a grille opening of a vehicle body front part and can open and close to change the amount of air flowing into a vehicle body; an electric motor M connected to the movable fin 11 through a power transmission mechanism 17; and a control unit 21 for performing drive control of the electric motor M so as to drive and control the movable fin 11 to any of a fully closed position, a fully opened position, and a half-opened position therebetween. When driving the movable fin 11 to the half-opened position, the control unit 21 drives the movable fin 11 to a position on a closing direction side from the half-opened position if the current position of the movable fin 11 is located at a position on an opening direction side from the half-opened position, and then drives the movable fin 11 to the half-opened position.SELECTED DRAWING: Figure 2 【課題】開閉部材が半開位置よりも閉方向側に動いてしまうことを防止することができるグリルシャッタ装置を提供すること。【解決手段】グリルシャッタ装置１０は、車体前部のグリル開口部内に設けられ、車体内に流れ込む空気の量を変更すべく開閉動作可能な可動フィン１１と、可動フィン１１に動力伝達機構１７を介して連結された電動モータＭと、電動モータＭを駆動制御して、可動フィン１１を全閉位置と全開位置とそれらの間の半開位置とのいずれかに駆動制御可能な制御部２１とを備える。制御部２１は、可動フィン１１を半開位置に駆動させるとき、可動フィン１１の現在の位置が半開位置よりも開方向側の位置にあると、可動フィン１１を半開位置よりも閉方向側の位置まで駆動し、その後、可動フィン１１を半開位置に駆動する。【選択図】図２
