The invention discloses an anticreeper of a porous material-filled thin-wall metal structure. The anticreeper comprises a fixed mounting base, a combined energy absorbing component and anticreeping teeth, wherein a first mounting tank structure is formed in the fixed mounting base; a second mounting tank structure is formed in the anticreeping teeth; the first mounting tank structure and the second mounting tank structure are respectively fixed at the two ends of the combined energy absorbing component; the combined energy absorbing component consists of a thin-wall metal structure and a porous filling piece; and the porous filling piece is filled in the thin-wall metal structure. The anticreeper improves the energy absorbing capacity and the lateral load bearing capacity. Meanwhile, the anticreeper has no need to reverse a giveaway space for collision at the back end of a vehicle body, so that the axial size of the anticreeper is largely reduced.
