Abstract

[Task] To provide a body structure of a vehicle that achieves a vibration damping function regardless of an input portion. [Solution] A body structure of a vehicle includes a second coupling member 40 made of fiber reinforced plastic including fibers impregnated with synthetic resin and a pair of rear fixing members 60 that have a bending rigidity higher than the second coupling member 40 and fix both end portions in the longitudinal direction of the second coupling member to a vehicle body, in which boundary portions B1 between the pair of fixing members 60 and the second coupling member 40 are formed in both end portions in the longitudinal direction of the second coupling member 40, and a distance D1 between the boundary portions on the rear side is different from a distance D2 between the boundary portions on the front side in the boundary portions B1 that extend along neutral axes A defined by the lines of intersection between the neutral plane of bending moments of the second coupling member 40 and the lateral cross sections of the second coupling member 40 when a bending load is input through the pair of rear fixing members 60 to the second coupling member 40.
