Vehicle body front structures

A vehicle body front structure comprising:

• a bumper beam;
• a side member;
• and
• a crash box including a polygonal tubular body, the crash box being disposed between an end of the bumper beam and the side member with an axis of the tubular body parallel to a front-rear direction of the vehicle, wherein the crash box absorbs impact energy as the tubular body is collapsed under a compressive load applied from the bumper beam;
• the polygonal tubular body including an outer sidewall and an inner sidewall, wherein the outer sidewall and the inner sidewall are both inclined laterally outwardly in the vehicle as they approach the bumper beam, wherein an inclination angle of the outer sidewall with respect to the front-rear direction of the vehicle is greater than an inclination angle of the inner sidewall;
• and
• the bumper beam having at the end a first portion whose front side surface is perpendicular to the front-rear direction of the vehicle and which extends from the terminal of the beam inwardly at least to the same lateral location as the laterally outer side of the side member.
