And, at least a portion of the overlapping portion 1 d is compressed in a direction perpendicular to the opening end surface Sh of the opening portion 1 h, to form a compressed portion 1 c.
  • FIG. 1 hatching to the plastic member constituting the fuel tank wall 1 is omitted to show the structure clearly.
  • the plastic member constituting the fuel tank wall 1 is the one with multiple layers, that includes an outer layer Po and an inner layer Pi, both of which are formed by the strength holding member, and an intermediate layer B which is formed with the barrier material and disposed between them, to be bound together by adhesive plastics.
  • the strength holding member employed in the present embodiment ultra high polymeric (high density) polyethylene is used.
  • the barrier material EVOH (i.e., plastic with ethylene and vinyl-alcohol co-polymerized) is used, for example.
  • the materials are not limited to those as described above, but may be employed any materials which can protect the fuel of gasoline or the like from being passed, to provide effective gas-barrier property.
  • the bent portion 1 b is bent inward (toward the opening) as shown in FIG. 2, so that even if the fuel passed through the inner layer Pi, it could be blocked by the intermediate layer B at the bent portion 1 b, effectively.
  • the compressed portion 1 c is formed to provide an annular groove, where the thickness of the outer layer Po is formed relatively thin, comparing with the thickness at the cylindrical portion 1 e .
  • the thickness of the outer layer Po is formed to be thin at the compressed portion 1 c, so that the passage has been made narrow, thereby to provide a resistance when the fuel is introduced from an opening end surface 1 p.
  • the opening end surface (corresponding to “ 1 p” in FIG. 2) of the plastic member with multiple layers can be directly communicated with the outer space. Therefore, even in the case where a seal member (not shown) was disposed between a cover member 4 and an annular fixing member 5 , the fuel might pass through the outer layer Po. Theoretically, some fuel might be introduced from the opening end surface 1 p to pass through the thin portion of the compressed portion 1 c , and reach the bent portion 1 b, according to the present embodiment, but the amount of fuel is so small as to be substantially negligible.
  • annular member 2 is placed to surround the opening portion 1 h, and fixed to the same with its inner side abutting on the outer side surface of the cylindrical portion 1 e, and with its top end surface abutting on the lower surface of the overlapping portion 1 d.

  • the plastic material is introduced into the communication holes 2 c, so that the annular member 2 is secured to the cylindrical portion 1 e not to rotate relative thereto.
  • the outer layer Po is extended to cover a portion of the outer peripheral end of the annular member 2 , to form an engaging portion 1 f.
  • the opening portion 1 h as constituted above has the compressed portion 1 c to provide an annular groove, which receives a sealing member 3 made of rubber or the like as shown in FIG. 1. Therefore, after the cover member 4 is placed on the sealing member 3 , the fixing member 5 having a threaded portion inside thereof is mounted on the cover member 4 , and engaged with the threaded portion 2 s of the annular member 2 . Consequently, the cover member 4 is tightly fixed to the upper surface of the overlapping portion 1 d through the sealing member 3 . When the fixing member 5 is screwed, the annular member 2 is not rotated, because the annular member 2 is secured to the cylindrical portion 1 e not to rotate relative thereto.
  • portions through which the fuel in the tank may be communicated with the outside of the tank are only the portions where the sealing member 3 abuts on the cover member 4 and overlapping portion 1 d, and the portion where the outer layer Po out of the multiple layers was formed relatively thin, when the compressed portion 1 c was formed.

  • a spacer SP is disposed to move back and forth perpendicularly to the axis of the die D 1 (i.e., the axis of the opening portion 1 h ).
  • the spacer SP is adapted to hold the annular member 2 within the recess 2 r of the annular member 2 in a pressing process.
