STRUCTURE OF VEHICLE

A structure of the vehicle includes a rear side member, a crush box and a bumper reinforcement. The rear side member is arranged outside in a width direction of the vehicle and is extended with a length direction of the rear side member coinciding with a longitudinal direction of the vehicle. The crush box plastically deforms through compression of the vehicle. The bumper reinforcement is provided with a hat-shaped open cross-section where a recess portion recessed outward with respect to the vehicle is provided in an inner surface of the bumper reinforcement in the longitudinal direction of the vehicle. A width of an open-end portion of the recess portion in a vertical direction of the vehicle is set larger than a width of the rear side member and a size of the crush box in the vertical direction of the vehicle.
