<P>PROBLEM TO BE SOLVED: To provide a vehicle body reinforcement structure excellent in rigidity and capable of restricting delayed fracture. Ž<P>SOLUTION: This vehicle body reinforcement structure comprises a vehicle body structure member 2 and an elongated vehicle reinforcement member 1 fixed to the vehicle body structure member 2 at a normal part 1b of a central side rather than a longitudinal end part 1a and having a protruded bending part 10 having a width sectional surface protruded toward the outside of the vehicle body while bending an ultra high strength steel plate. The protruded bending part 10 has a corner part 13 protruded in opposition to the outside of the vehicle body. A radius curvature of the corner part 13 at an end part 1a of the reinforcement member 1 is larger than a radius curvature of the corner part 13 at the normal part 1b of the reinforcement member 1.
