Abstract: A front subframe structure includes a subframe body and a pair of right and left longitudinal members. The subframe body includes an arm front-side supporting portion, an arm rear-side supporting portion, and a detaching portion. Each of the longitudinal members has, in the rear part thereof, a bent portion that is further in the vehicle width direction outer side with respect to the arm front-side supporting portion. A lower arm has, in the rear part thereof, a longitudinally extending portion. The rear face portion of the bent portion, and the front face portion which is in the front side of the longitudinally extending portion of the lower arm extend substantially parallel to each other along the vehicle width direction. A reinforcing portion is provided on a face of the rear face portion of the bent portion, the face opposing the front face portion of the longitudinally extending portion.

Abstract: A reinforcing member is provided inside a closed cross section of a front side frame at a position, in a vehicle longitudinal direction, which corresponds to a forming position of a bead. The reinforcing member extends between an outward side wall portion and an inward side wall portion of the front side frame. The reinforcing member is joined to the outward side wall portion and the inward side wall portion of the front side frame. A joint length, in the vehicle longitudinal direction, of the reinforcing member and the inward side wall portion is set to be longer than that of the reinforcing member and the outward side wall portion.

Abstract: A front vehicle-body structure comprises a crash can fixed to a front end of a front frame. The crash can comprises an upper face portion, a lower face portion, a pair of side face portions, corner portions respectively positioned between the side face portion and the upper face portion and between the side face portion and the lower face portion, a first fragile portion provided at each of the corner portions, and a second fragile portion provided at each of the side face portions. The first fragile portion is configured to be deformed before the second fragile portion when a collision load applied toward a vehicle rearward side is inputted to an extension portion of a bumper beam. The second fragile portion is configured to be deformed before the front frame when the collision load applied toward the vehicle rearward side is inputted to the extension portion.

Abstract: A vehicle front body structure is provided for reliably transferring a collision load to a crash can and a front frame by preventing a bumper beam from buckling during a small overlap collision. Bending rigidity of the bumper beam in a vehicle width direction is such that 1) a bending moment generated on the bumper beam when a collision load in a direction toward a vehicle rear side is applied to an extending section, which extends outward in the vehicle width direction from a crash can fixed section, is the highest in a vehicle width direction inner end portion of the crash can fixed section on a side where the collision load is applied, and 2) the bending moment is continuously reduced as a distance from the vehicle width direction inner end portion in the vehicle width direction increases.

Abstract: A fragile portion is provided at a portion of a suspension arm which is positioned near a vehicle-body attachment portion. The fragile portion is configured such that when a load which is greater than a specified magnitude is inputted to a front wheel from a vehicle forward side, the suspension arm is bent at the fragile portion, whereby the front wheel is rotated rearwardly around the fragile portion.
