an opening disposed on the outer side in the vehicle width direction in the front part of the vehicle; a cooling device disposed at the vehicle rear of the opening; and a guide portion disposed between the opening and the cooling device and guiding traveling air to the cooling device, in which the guide portion has a tubular main body portion extending in the longitudinal direction of the vehicle, and an extension portion extending toward the center in the vehicle width direction from the main body portion and guiding traveling air from the front grille opening to the cooling device. ## Claims ### Claim 1 A vehicle front structure comprising: a front grille opening disposed at the center in a vehicle width direction in a vehicle front part; a radiator disposed at a rear of said front grille opening; a second opening disposed on an outer side in the vehicle width direction in said vehicle front part; a cooling device disposed at a rear of said second opening; a guide portion disposed between said second opening and said cooling device and guiding traveling air from said second opening to said cooling device; and a vehicle component having a stay portion connected to an end portion of said radiator in the width direction, and a plate portion connected to said stay portion, wherein: said guide portion comprises a tubular main body portion extending in a longitudinal direction of said vehicle, and an extension portion extending toward the center in the vehicle width direction from the main body portion and guiding traveling air from said front grille opening to said cooling device, wherein said extension portion is offset rearwardly relative to said radiator, said guide portion is disposed on an outer side of said radiator in the vehicle width direction, and said vehicle component is disposed at a position located in an extending direction of said extension portion. ### Claim 2 (depends on 1) The vehicle front structure according to claim 1 wherein said stay portion is bent from the end portion of said radiator toward the vehicle rear, and said plate portion extends upward from the stay portion, wherein: said extension portion guides, to said cooling device, traveling air flowing through a space between said front grille opening and said radiator and flowing along said vehicle component toward the vehicle rear. ### Claim 3 (depends on 2) The vehicle front structure according to claim 2, wherein: said extension portion has an extension wall extending in a vehicle forward direction while being inclined toward the center in the vehicle width direction; and said plate portion is disposed along the inclination of said extension wall. ### Claim 4 (depends on 1) The vehicle front structure according to claim 1, wherein: a vertical dimension of said extension portion is smaller than a vertical dimension of said main body portion. ### Claim 5 (depends on 1) The vehicle front structure according to claim 1, further comprising a wheelhouse portion disposed at the rear of said cooling device and housing a front wheel, wherein said wheelhouse portion includes a front side face portion including a plurality of through holes connecting a space located on the vehicle rear side of said cooling device and a space inside said wheelhouse portion; and said extension portion extends so as to block the space on the vehicle rear side of said cooling device. ### Claim 6 (depends on 1) The vehicle front structure according to claim 1, wherein: a fog lamp is attached to said second opening so that said fog lamp partially closes said second opening and an opening open in the vehicle longitudinal direction is formed in a part of the second opening; a dimension of said guide portion in the vehicle width direction is substantially the same as or larger than a dimension of said fog lamp in the width direction in front view of the vehicle; and a vertical dimension of said extension portion is substantially the same as or larger than a vertical dimension of said fog lamp in the front view of the vehicle. ### Claim 7 (depends on 6) The vehicle front structure according to claim 6, wherein: a front end of said extension portion is set back in a vehicle rear direction from a front end of said main body portion. ### Claim 8 (depends on 1) The vehicle front structure according to claim 1, wherein: said second opening is positioned on an outer side of said front grille opening in the vehicle width direction. ### Claim 9 (depends on 2) The vehicle front structure according to claim 2, wherein: said extension portion includes a front opening at a front end thereof. ### Claim 10 (depends on 3) The vehicle front structure according to claim 3, wherein: said plate portion is disposed aligned with the inclination of said extension wall. ### Claim 11 (depends on 3) The vehicle front structure according to claim 3, wherein: said extension wall is a rear wall. ### Claim 12 (depends on 1) The vehicle front structure according to claim 1, wherein: said guide portion is disposed entirely on the outer side of said radiator in the vehicle width direction.
