    • To provide a fuel sealing structure capable of preventing the leakage of not only liquid fuel but also gasified fuel, an annular packing 30 is interposed between an annular sealing surface 15 on an opening part 11 of a container 20 and an annular sealing surface 25 of a closure 20. The distance between the second regions 15b, 25b of the sealing surfaces 15, 25 is shorter than that between the first regions 15a, 25a. The packing 30 includes a first sealing part 31 sandwiched between the first regions 15a,25a and a second sealing part 32 sandwiched between the 15b, 25b. The second sealing part 32 is smaller in thickness than the first sealing part 31 and the difference of the thicknesses is larger than the difference of distances between the above-mentioned regions. With the closure 20 attached, the compression ratio of the second sealing part 32 is smaller than that of the first sealing part 31.
    • 为了提供能够防止液体燃料而且气化燃料泄漏的燃料密封结构,环形密封件30插入在容器20的开口部11上的环形密封表面15和位于容器20的环形密封表面25之间 封闭20。 密封表面15,25的第二区域15b,25b之间的距离比第一区域15a,25a之间的距离短。 填料30包括夹在第一区域15a,25a和夹在15b,25b之间的第二密封部分32的第一密封部分31。 第二密封部件32的厚度小于第一密封部件31,并且厚度差大于上述区域之间的距离差。 在封闭件20附接时,第二密封部32的压缩比小于第一密封部31的压缩比。
