Abstract
A stiffness reinforcement structure for a fuel tank of a vehicle is capable of maintaining the stiffness of the fuel tank even with changes in pressure such as positive pressure and negative pressure in the fuel tank. In particular, a stiffness reinforcement column inside a fuel tank made of a plastic material is capable of preventing heat fused portions between the reinforcement column and the upper and lower plates of the fuel tank from being ruptured by allowing the stiffness reinforcement column to have self-reactive impact dispersion movement in case of a vehicle collision accident.
