PURPOSE: Structure for preventing rear impact of a fuel tank in a vehicle is provided to improve safety of the vehicle by restricting the rear side member and the rear cross member from being bumped into the fuel tank with integrally mounting a reinforcing member in the rear side member. CONSTITUTION: A rear impact preventing system of a fuel tank is composed of two rear side members(2) installed laterally to form both sides of a vehicle body, a rear cross member(3) installed perpendicularly to the rear side members to connect the rear side members, and a reinforcing member(303) protruded integrally in the rear side member to prevent breakage of the fuel tank by restricting lateral or horizontal torsion or bending. The rear side member is restricted from being pushed forward by bumping the reinforcing member to a wheel(10) at a rear-end collision, and breakage of the fuel tank is prevented by restricting direct impact to the fuel tank from the rear side member or the rear cross member.
