Patent attributes
A front vehicle-body structure is characterized in that each of front side frames includes outer and inner members. The outer and inner members have vertical wall surface portions in which a recessed bead extending from a front side to at least a position next to a suspension tower portion in a vehicle front-rear direction is formed. A reinforcement extending in the vehicle front-rear direction and in an up-down direction that divides a closed cross-section of the front side frame into left and right is included between the members of the front side frame to which the suspension tower portion is connected. The reinforcement is formed to join to upper flange portions and lower flange portions of the members of the front side frame with the reinforcement being interposed between the upper flange portions and between the lower flange portions and to linearly extend in the up-down direction.
