Abstract
A crush box includes a tubular body having a polygonal section and disposed between an end portion of a bumper beam and a vehicle body in such a posture that an axial direction of the tubular body generally coincides with a longitudinal direction of a vehicle, in which the tubular body has an outer side wall and an inner side wall that is located inward of the outer side wall in a vehicle-width direction, and both the outer side wall and the inner side wall are inclined outward in the vehicle-width direction, in a direction from the vehicle body toward the bumper beam, and in which the tubular body is crushed into a bellows shape to absorb impact energy as a compressive load is applied to the tubular body from the bumper beam in the axial direction of the tubular body, wherein an angle of inclination of the outer side wall is greater than an angle of inclination of the inner side wall.
