A grille shutter unit which is provided with plural shutters extending in a vehicle width direction is attached to a frame-shaped shroud, a center stay is provided to extend in a vertical direction and connect a central portion, in a width direction, of a shroud upper and a central portion, in the width direction, of a shroud lower, the grille shutter unit is attached to a back-face side of the shroud, and an actuator (driving actuator) for opening/closing the shutters is arranged at a back-face side of the center stay.

Grille shutter attaching structure of automotive vehicle

A grille shutter unit which is provided with shutters and a frame which pivotally supports shutter shafts provided at the shutters is attached to a frame-shaped shroud which supports heat exchangers. The grille shutter unit is configured to be attached to the shroud from a back-face side of the shroud at a position located in front of the heat exchangers.

A vehicle is provided, which includes an engine bay having an upper wall, side walls, a front wall, and a rear wall, an engine disposed inside the engine bay, an upper lid part disposed inside the engine bay and covering the engine from above, a shroud disposed inside the engine bay and formed in a frame shape having an opening disposed forward of the engine, and a grille shutter provided to the shroud and configured to open and close the opening. A front end of the upper lid part is placed on an upper side of the shroud, and the grille shutter is closed when an ignition is off.

Engine heat retention structure

Provided is a vehicle shutter capable of detecting a flap to which power transmission is cut off by providing turn restriction units each having a simple structure in flaps. The vehicle shutter is provided with: a plurality of flapscapable of opening and closing an outside air introduction pathfor introducing outside air into an engine compartment and arranged in parallel to each other so as to cross the outside air introduction path; a linkage operation section linking the flapswith each other to perform an opening/closing operation of the flaps; a drive section driving the flapsto be open and closed through the linkage operation section; an abnormality detection section detecting an abnormality of the flapson the basis of an operating state of the drive section; and an abnormality notification section notifying the abnormality to a user on the basis of output from the abnormality detection section. Opening failure detecting restriction unitsand closing failure detecting restriction unitsare formed on adjacent flapsas turn restriction units which restrict, when power transmission to one of the adjacent flapsfrom the drive section is cut off, the other flapfrom turning.

Vehicle shutter

A grill shutter unit comprises a shutter unit provided in back of a traveling-air introductory port formed at a front end of a vehicle body and including shutter members, and a traveling-air guide member including a guide frame portion provided at an outer peripheral edge portion of the shutter unit and a seal portion provided to extend forward continuously from a front end of the guide frame portion and be made from soft synthetic resin having more flexibility than the frame portion, wherein the grill shutter unit is configured such that when the shutter members are closed, a seal portion of the traveling-air guide member is pressed against an outer peripheral wall face of the traveling-air introductory port by pressure of traveling air shut off by the shutter members closed.
