<p>Provided is a blow-molded impact absorber that has different impact-absorbing characteristics in at least two sections thereof, or an impact absorber that can absorb an impact effectively even in cases where the impact is applied partially and in a concentrated manner or where there are constraints on the shape etc. of the impact absorber. Also provided is a process for producing the impact absorber. The impact absorber (1) is made up of a hollow body (11) having a plurality of ribs (6, 7, 15). The hollow body (11) is characterized by having: a section (41) in which the density of the ribs (6, 7, 15) is low; and a section (42) in which the density of the ribs (6, 7, 15) is high.</p> |
