Description of the Related Art As shown in FIGS. 8 to 13, a fuel injection port of a conventional automobile is provided at the bottom of a fuel inlet box 52 attached to a vehicle body 51 and is closed by a cap 53. I have. A fuel lid 54 is rotatably attached to the inlet box 52 via a hinge member 55, and the fuel lid 54 covers a box opening 52a located outside the fuel inlet so as to be openable and closable. The fuel lid 54 is configured by assembling a lid body 56 and a reinforcing plate 57 with each other, and a cap holding portion 58 formed in a hook shape by projecting a part of the reinforcing plate 57 is provided on the back surface thereof. ing. Note that in FIG.
Reference numeral 9 denotes an inlet pipe having one end connected to a fuel tank (not shown).

[0003] However, at the time of fuel injection, an operator is required to operate as shown in FIG.
The fuel lid 54 is fully opened as shown in (1), and the cap 53 is removed from the fuel inlet. Next, this cap 5
3 is placed on its side, and the screw 53a of the cap 53 is hooked on the upper edge of the cap holding portion 58, so that the cap 53 is attached to the rear surface of the fuel lid 54. In this state,
Holding the injection gun 60 and inserting it into the fuel injection port, the fuel is injected into the fuel tank. Therefore, the worker does not perform the fuel injection work with the cap 53, and the cap 53 is not dropped or lost during the work. After the fuel is injected, the cap 53 is picked up from the cap holding portion 58, tightened to the fuel inlet, and the fuel lid 54 is closed, thereby completing the fuel injection operation.

[0004]

In addition, there is a problem that the fuel injection operation is difficult to perform, and the cap 53 comes off from the cap holding portion 58 and easily falls due to a hand of an operator touching the fuel injection operation. In order to ensure the clearance between the cap 53 and the injection gun 60, it is necessary to increase the L dimension between the hinge center O of the fuel lid 54 and the center C of the fuel inlet. That is, as shown in FIGS. 13 and 14, the La size when the cap holding portion 58 is provided must be larger than the Lb size when the cap holding portion 58 is not provided.

[0005] However, if the above L dimension is made large,
The parting position between the fuel lid 54 and the vehicle body 51 is restricted, and it is necessary to use a large fuel lid 54. On the other hand, in order to secure a clearance between the cap 53 and the injection gun 60, it is possible to use a hinge member 65 of a dogleg type as shown in FIG. 15, but the hinge structure becomes complicated and cost increases. There was a fear.
