IMPACT-ABSORBING MEMBER, AND PULL-UP TYPE CONTINUOUS CASTING DEVICE AND PULL-UP TYPE CONTINUOUS CASTING METHOD FOR CASTING IMPACT-ABSORBING MEMBER

摘要

An impact-absorbing member according to one aspect of the present invention is provided with a rectangular tubular main body section (10) having two pairs of side walls (11, 12) and side walls (13, 14) that each face each other, and a tabular rib (15) provided inside the tube of the main body section (10) and extending in an axial direction. Of the two pairs of side walls (11, 12) and side walls (13, 14) facing each other, at least the one pair of side walls (11, 12) facing each other and the rib (15) have a wave shape in the axial direction. Impact energy absorption performance can thereby be improved.
