A front frame structure of a cab over type vehicle comprises a side member provided in a longitudinal direction of the vehicle, an aluminum-made frame section connected with the front end of the side member, a front cross member connected with the front end of the frame section, a front bumper provided adjacent to the he front cross member, and an aluminum foam inserted in the frame section. When a head-on impact is applied to the vehicle body, an impact energy is transmitted to the aluminum-made frame section through the bumper and the front cross member and the frame section is subjected to a buckling deformation together with the aluminum foam contained therein. The impact energy can be effectively absorbed within a small crush space of the vehicle.
