Abstract: A vehicle front structure has a rectangular frame-shaped bulkhead provided in a front part of a vehicle to support a heat exchanger. The bulkhead includes vehicle fixation portions for fixing the bulkhead to a vehicle body and step portions provided below the vehicle fixation portions. A width dimension in a vehicle front-rear direction of a part of the bulkhead above each step portion is the same as a width dimension in the vehicle front-rear direction of a part of the bulkhead below the step portion.

Abstract: A vehicle front portion structure includes: a rear end part that constitutes a rear part of a front side frame and has an inclination portion which is inclined downward toward a vehicle rearward direction; a fixation portion that is provided on the inclination portion; and a lower arm that is connected to the fixation portion. The inclination portion includes: a bottom section that is inclined downward toward a vehicle rearward direction; and a protrusion section that protrudes further upward than the bottom section. The protrusion section extends toward a vehicle rearward direction from a vehicle forward position further than the fixation portion, and a middle side in a vehicle width direction of the protrusion section protrudes further upward than an outside in the vehicle width direction of the protrusion section.

Abstract: A vehicle body front structure includes a front side frame body provided on the front portion of the vehicle body, the front side frame including a front frame extending to the longitudinal direction and a rear frame extending downward from the rear end portion of the front frame to the rear direction, the rear portion of the front frame has a front bulkhead and a rear bulkhead which are longitudinally spaced from each other, a recessed portion which recesses the outside wall outside in the width direction of the vehicle to the inside in the width direction of the vehicle, and the recessed portion is positioned between the front bulkhead and the rear bulkhead.

Abstract: There is provided a vehicle body front structure in which left and right frame side mounting members for connecting the rear ends of left and right bumper beam extensions are provided at the front ends. The left and right front side frames are formed from left and right side inner panels and left and right side outer panels. The left and right side outer panels are formed from left and right rear outer panels and left and right front outer panels. The left and right front outer panels are formed from left and right side plates, left and right upper plates, and left and right lower plates. At least one of the set of the left and right upper plates and the set of the left and right lower plates is formed by members different from the left and right side plates.

Abstract: A vehicle body front structure has: a front side frame; a lateral member; a sub frame; a sub frames attaching portion for fastening the rear end portion of the sub frame. The lateral member has a lateral member main body which has a hole portion formed on a bottom wall, and a stiffening member which is made of a material with lower tensile strength than the lateral member main body, layered on the bottom wall of the lateral member main body, joined to the inside of the lateral member main body, and simultaneously in which a fastening nut is disposed in the upper direction. The hole portion has a large-diameter hole with a larger diameter than the fastening nut, a notched portion notching the edge of the large-diameter hole. The stiffening member has a recessed wall portion recessed downward corresponding to the hole portion.
