Abstract
In a frame having a closed-section portion which is formed by joining a first member having a U-shaped section and a second member having a flat-plate shape, a bulkhead is provided in the closed-section portion as a reinforcing member, flanges of the bulkhead and the first and second members are joined with a rigid joint portion where they are joined by a spot welding and a flexible joint portion where they are joined via a damping member. Thereby, transmission of vibrations can be properly restrained, improving the rigidity of the portion having the closed-section portion.
