The front frame made by stamping the TB is developed. At the first, the requirement of the front frame is studied and the TB concept is designed and the computer simulation of stamping and crash is performed. After the above study, the first TB concept design is modified for the making mold and the forming. The stamped TB front frame was tested by compressing as the front frame only in the UTM. The collapse mode and load was checked with the deformation. In result, it is possible to raise up the crush performance of the front frame and at the same time to reduce the 20% weight reduction, and also the collapse mode of the front frame at the test can be changed from bending to axial collapse by the bead shape control.<br/>
