    摘要: The present invention is directed to an opening structure of a fuel tank having a fuel tank wall (1) made of a plurality of plastic layers with an opening portion (1h) formed to be integral with the fuel tank wall. The opening structure includes a cylindrical portion (1e) extended from the opening portion outward of the fuel tank wall, an overlapping portion (1d) extended from an end of the cylindrical portion to enlarge the diameter of the opening portion and bent at a bent portion (1b) to form an outer surface parallel with an opening end surface of the opening portion, and a compressed portion (1c) with at least a portion of the overlapping portion compressed in a direction perpendicular to the opening end surface of the opening portion. The opening structure may further include an annular member (2) which is disposed around the opening portion to be in contact with the overlapping portion and the cylindrical portion. The plastic layers may include at least an outer layer, an inner layer and an intermediate layer, and the outermost end of the intermediate layer may be positioned at the compressed portion.
