Title:
FUEL SEALING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2005/087605
Kind Code:
A1
Abstract:
A fuel sealing structure capable of excellently restricting transmission of a gasified fuel in addition to preventing leakage of a liquid fuel. A fuel sealing structure where an annular packing (30) is interposed between an annular sealing surface (15) of an opening section (11) of a fuel tank and an annular sealing surface (25) of a sealing body (20). The sealing surfaces (15, 25) of the opening section (11) and the sealing body (20) are constituted of annular first regions (15a, 25a) and annular second regions (15b, 25b), respectively. With respect to the distance between the sealing surfaces (15, 25) of the opening section (11) and the sealing body (20), the distance between the second regions (15b, 25b) is less than the distance between the first regions (15a, 25a). The packing (30) has a first sealing section (31) and a second sealing section (32) corresponding to the first regions (15a, 25a) and the second regions (15b, 25b). The second sealing section (32) has a smaller thickness in a natural state than the first sealing section (31), and the difference in the thickness is greater than the difference between the distance between the first regions (15a, 25a) and the difference between the second regions (15b, 25b).
