Therefore, two members are required, one for slightly lifting the tip of the refueling palate 110 and the other for holding the refueling palate 110 in the open position, which increases the labor and cost of assembly.

Therefore, there is one that uses the spring member 240 shown in FIG. 11 (see, for example, Patent Document 1). In this case, the main body side fixing portion 241 of the spring member 240 is fixed to the box portion, the lid member side fixing portion 242 is attached to the arm of the lid member, and the spring member 240 is expanded and contracted in a direction perpendicular to the expansion and contraction direction. The urging force is used to exert both the urging force for slightly lifting the tip of the refueling port lid 110 and the urging force for holding the refueling port lid 110 in the open position.

However, in this case, in order to slightly lift the tip of the fuel filler lid 110, the arm of the lid member is pushed by the spring member main body 243 which is the central portion of the spring member 240, so that the dimensions and shape of the arm of the lid member are different. In this case, it is necessary to adjust the overall shape of the spring member 240 and the dimensions of both the arm of the lid member.
Therefore, the versatility of the spring member 240 was low.

After that, the tip of the refueling palate 10 whose tip is raised can be lifted by hand to completely open the refueling palate 10. At this time, the spring pressing protrusion 27 prevents the opening / closing spring 40 from rotating, and the tip of the fuel filler palate 10 can be reliably raised.

When the fuel filler lid 10 is completely opened, the box mounting arm 23 of the mounting arm member 20 rotates to the position described by the two-dot chain line shown in FIG. Then, the opening / closing spring 40 that has been compressed and attached between the opening / closing spring arm mounting portion 41 and the opening / closing spring box mounting portion 42 is opened to prevent the box mounting arm 23 from rotating, and the refueling palate 10 is opened during refueling. It can be prevented from being closed by its own weight.
When closing the refueling palate 10, the refueling palate 10 can be closed by hand against the urging force of the opening / closing spring 40.

As described above, the opening / closing spring box contact portion 44 of the opening / closing spring 40 is formed by bending from the opening / closing spring arm mounting portion 41, and the urging force due to expansion and contraction between the opening / closing spring arm mounting portion 41 and the opening / closing spring box mounting portion 42. The urging force due to the bending of the opening / closing spring box contact portion 44 is generated in another portion of the opening / closing spring 40.

Therefore, even if the shapes of the mounting arm member 20 and the fuel filler port box 30 change, the angle and dimensions of the opening / closing spring box contact portion 44 can be adjusted, and the opening / closing spring arm mounting portion 41, the opening / closing spring main body portion 43, and the opening / closing spring box can be adjusted. The size of the mounting portion 42 can be adjusted separately, and the opening / closing spring 40 can be easily mounted by adjusting the shape of the mounting arm member 20 and the fuel filler port box 30.
