A vehicle front body structure includes a duct member that surrounds a radiator on an inner side in a vehicle width direction of a right and left pair of crash cans. The duct member is a member that completely surrounds the radiator and includes side duct sections and an upper duct section. The side duct sections and the upper duct section are connected such that, when the duct member receives a specified load from a bumper member of a body during a frontal collision, the side duct sections and the upper duct section are disengaged from each other in the engagement sections.

Vehicle front body structure

Provided is a frame structure of a vehicle comprising a front side frame; a reinforcing member disposed in a closed cross section; and an inner bead portion which is formed from a plurality of ridgelines extending vertically on a side wall of the front side frame and projects inwardly into the closed cross section, in which the side wall has the front inclined planar portion which includes a line connecting the upper end portion of the intermediate ridgeline with the middle portion of the front ridgeline; and the rear inclined planar portion which includes a line connecting the upper end portion of the intermediate ridgeline with the middle portion of the rear ridgeline, and the reinforcing member is joined to the front proximal portion and the rear proximal portion of the intermediate ridgeline, which are the front and rear inclined planar portions.

Frame structure of vehicle

In a lower vehicle-body structure of a vehicle which comprises a suspension cross member, a side member, and first and second reinforcing members which are provided in a closed cross section formed by the side member and a slant portion, the suspension cross member being fixed by fastening a bolt which is inserted through the suspension cross member to a weld nut which is vertically fixed to a bottom plate portion of the side member, the first reinforcing member is joined to a front-side semicircular portion of a peripheral portion of the weld nut and the second reinforcing member is joined to a rear-side semicircular portion of the peripheral portion of the weld nut.
