PROBLEM TO BE SOLVED: To provide a vehicle body structure of a vehicle which can enhance a vibration attenuation effect of a bending mode, together with those of a twisting mode and a rhomboid mode.SOLUTION: A joint part of a vehicle body constituent member 4 and a reinforcement body 5 has rigid connection parts a, b and c connected in a contact state and a flexible connection part 7, and the flexible connection part 7 is bonded through an attenuation member V between a flexible flange part 6 and the vehicle body constituent member 4 which is formed so as to be perpendicular to the closed section direction of a closed section part 3 and nearly in parallel with one inner wall of the closed section part. The length of the flexible connection flange part 6 in the direction perpendicular to the closed section direction of the closed section part 3 is greater than the length of the closed section part 3 in the closed section direction. In the flexible flange part 6, vertical flange parts 8 and 9 or a bead part extending in the direction nearly perpendicular to the closed section direction of the closed section part is formed. |
