After the front part of a longitudinal(130) is inserted on the rear of an impact beam(110), an inserting part(112) is formed so as to be combined by a screw(140), and a screw hole(134) is formed on the flange(132) and the upper surface of a longitudinal, respectively. The combination between the impact beam and the longitudinal is completed by being combined with the screw(140) after the flange on which the screw hole is formed is inserted through the inserting part formed on the rear of the impact beam.
