FRONT VEHICLE BODY STRUCTURE OF VEHICLE

PROBLEM TO BE SOLVED: To maintain or improve the energy absorbed amount of a crash can while contributing to the weight saving of a vehicle.SOLUTION: In a front vehicle body structure of the vehicle which is provided with a cylindrical crash can 50 connected to the front end part of a front side frame 10 and extended to the vehicle front back direction, the cross-sectional shape of the crash can 50 in a surface vertical to the buckling axis P1 of the crash can 50 is a closed cross-sectional shape in which a projected part 53 having a top side 53a and a recessed part 57 having a bottom side 57a are alternately arranged in the peripheral direction. The closed cross-sectional shape is set up by setting the every other sides of an even projected polygon equal to or above hexagon as a top side 53a of the projected part 53 extending first wall surface parts 53b from both end part of the top side 53a to the inner side of the polygon, and by forming a second wall surface part 57a connecting the first wall surface parts to each other in a position on the outer side of the polygon from an intersection point O as the bottom side of the recessed part 57 when it is assumed that the adjacent first wall surface parts extended and set from the different top side are crossed to each other.
