Abstract
A fuel tank for a motor vehicle, which exhibits high fuel permeation preventing properties and a sufficiently good rigidity, and can be manufactured readily with an excellent quality, and the method for producing such a fuel tank. The fuel tank has an upper tank and a lower tank which are respectively composed of a thermoplastic synthetic resin. Peripheral parts around open ends of the upper tank and the lower tank are joined together to form the fuel tank. The upper tank and the lower tank respectively have an inner resin layer and an outer resin layer. The outer resin layer is previously formed by preforming a thermoplastic synthetic resin sheet, and the inner resin layer is formed on an interior surface of the outer resin layer by injection molding. Ribs are integrally formed in the inner resin layer so as to project into an interior of each tank.
