A grille shutter device opens and closes an introduction passage through which air is introduced from an opening provided at a front part of a vehicle to the inside of the vehicle. The grille shutter device includes: a driving fin and a driven fin that are configured to rotate between an open position in which the introduction passage is open and a closed position in which the introduction passage is closed; an actuator configured to drive the driving fin; a power transmission member configured to transmit power from the driving fin to the driven fin; and a first stopper configured to define a first position by coming into contact with the power transmission member.

Grille shutter device

A grille shutter includes a frame, a fin supported by the frame, and brackets that are arranged respectively on opposite sides of the frame in the vehicle right-left direction and used for attaching the frame to a vehicle body. Each of the brackets is partially provided with a fragile portion.

Grille shutter

A grille shutter includes a frame, a movable louver and a bracket provided at each of end portions of the frame. The frame includes an upper frame portion, a lower frame portion, a right frame portion and a left frame portion, wherein at least one of the upper frame portion and the lower frame portion includes a curved configuration in which a vehicle-rear-side edge of a portion of the one of the upper frame portion and the lower frame portion is convex towards a vehicle-front side, and the portion is positioned between the right frame portion and the left frame portion.

A fragile portion is provided at a portion of a vertical frame bar. When an impact load from under a vehicle is applied to a grille shutter, the impact can be at least partially absorbed as the fragile portion undergoes plastic deformation (including damage). Thus, the impact exerted on a portion of the vertical frame bar other than the fragile portion is mitigated, and a fin can be restrained from coming off a frame. Moreover, the fin can be restrained from coming off the frame by a compact structure, because simply providing the fragile portion at a portion of the vertical frame bar can achieve that.

A spoiler unit includes a movable spoiler for a vehicle, a frame fixing the movable spoiler to the vehicle, and a cover being mounted on the frame.
