PURPOSE: A flow preventive device of fuel in a fuel tank is provided to decrease noise in slopping by restricting flow of fuel in suddenly stopping or starting a vehicle with mounting a resistance unit against flow of fuel. CONSTITUTION: Plural baffles(11) are installed vertically in a fuel tank with standing, and plural flow holes(12) are formed in the baffles. A resistance unit(20) is formed in the flow hole to prevent fuel from rippling by resisting against flow of fuel. Plural blades(21,22) are protruded from the inner periphery of the flow hole for the center of the resistance unit. The blades are expanded around the baffles, and inclined opposite to the other blades. Noise is reduced by restricting rippling of fuel in the fuel tank with the resistance unit.
