The inner convex portion 2 extends toward the inside of the longitudinal beam front section assembly 1. The inner convex portion 2 increases the level of the longitudinal beam front section assembly 1 between the first bent portion 11 and the second bent portion 12, so that the side of the longitudinal beam front section assembly 1 is not easily deformed when it is impacted by external force.
