Abstract
A crash energy absorption member formed from a tubular body for absorbing impact energy by buckling when it receives an impact load in the axial direction from one end in the axial direction. It has a transverse cross-sectional shape along at least a portion in the axial direction which is a closed cross section having a plurality of vertices in which there is no flange on the outside of the closed cross section, and in a region of at least one side of a basic cross section formed from the largest outline obtained by connecting a portion of the plurality of vertices by straight lines, a groove which is recessed towards the inside of the outline is provided in a location other than at an end point of the side. Thus, the crash energy absorption member can achieve a prescribed amount of shock absorption by stably buckling in the axial direction without bending and without an increase in weight due to the addition of a partition or due to an increase in plate thickness.
