a frame-shaped shroud;
a grille shutter unit provided with plural shutters extending in a vehicle width direction; and
a center stay provided to extend in a vertical direction and connect a central portion, in a width direction, of a shroud upper of the shroud and a central portion, in the width direction, of a shroud lower of the shroud, wherein
said grille shutter unit is attached to a back-face side of said shroud, and a driving actuator for opening/closing said shutters is arranged at a back-face side of said center stay of said grille shutter unit,
said center stay is configured such that a lower part thereof is wider than an upper part thereof, and said driving actuator is arranged at a back-face side of the lower part of the center stay,
a center frame which is provided at said grille shutter unit is attached to the back-face side of said center stay along the center stay, an actuator arrangement part, in the vertical direction, of said center frame where said driving actuator is arranged is configured to be wider than the other part of the center frame, and an actuator housing portion where the driving actuator is housed is formed at said actuator arrangement part,
a driving link which transmits a driving force of said driving actuator to said shutters is arranged along said center frame, and
a latch housing portion where a latch of a bonnet is housed is provided at said central portion, in the width direction, of the shroud upper such that the latch housing portion protrudes toward an opening portion which is formed at an inside, in an elevational view, of said frame-shaped shroud, right-and-left indirect swing shutters which are not driven directly by said driving link are provided on right-and-left both sides of said latch housing portion, and a second driving link which is different from said driving link is provided on an outward side, in the vehicle width direction, of said indirect swing shutters so as to drive the indirect swing shutters.
