Abstract: Provided is an air cleaner that can take a large amount of air in a large space into a dust collector with good efficiency while being lightweight and having easy maintenance. An air cleaner is provided with a drone and a dust collector. The drone has a main body unit and propellers attached to the tips of frames. The dust collector has electric discharge electrodes and a dust collection electrode. The electric discharge electrodes are connected to a booster unit within a central chamber. The booster unit is electrically connected to a control unit in the main body unit. Electric discharge is formed between the dust collection electrode and the electric discharge electrodes, and dust particles in the air are charged and collected by the dust collection electrode.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
