  As described above, the inlet box assembly of Patent Document 1 has a configuration in which the clip tip locking portion 136 of the locking clip 130 is locked to the arm member 120. For this reason, in addition to the time when the fuel filler lid 100 is fully opened and the time when the refilling lid 100 is started to be closed from the fully opened position, the clip tip locking portion 136 of the locking clip 130 is elastically bent, and the arm member tip lock of the arm member 120 is elastically bent. It is necessary to get over the end of the stop 126. For this reason, when opening and closing the fuel filler lid 100, the arm member 120 and the locking clip 130 rub against each other, and the painting of the arm member 120 is peeled off, and the arm member 120 is easily rusted.

  The present invention has been made to solve the above problems, and an object of the present invention is to solve the problem of rust in a mechanism for holding a movable portion such as a fuel filler lid in a fully opened state with respect to a fixed portion. It is to prevent occurrence.

  The above-mentioned subject is constituted by the invention of each claim. A first invention is an inlet box assembly for a vehicle, which houses an energy supply unit for supplying energy required for driving the vehicle, and covers the fixed unit fixed to the vehicle body and the energy supply unit. A movable portion connected to the fixed portion so as to be movable between a position and a position exposing the energy supply portion, wherein the fixed portion and the movable portion are made of a non-metallic flexible material. The flexible portion of the fixed portion and the flexible portion of the movable portion are fitted in a state where the movable portion has been moved to a position exposing the energy supply portion to the fixed portion. The movable part is held with respect to the fixed part.

  According to the present invention, in a state where the movable section has moved to a position where the energy supply section is exposed, the flexible section of the fixed section and the flexible section of the movable section are fitted to each other so that the movable section is fixed to the fixed section. Will be retained. That is, since the movable portion is held by the fixed portion by fitting the flexible portions of the fixed portion and the movable portion, even if the movable portion moves with respect to the fixed portion, the fixed portion or the movable portion is moved. No metal parts are rubbed. Thereby, the coating of the metal part does not come off and rust does not occur.

It covers the entire wall of the part. For this reason, the structures that constitute the storage space of the energy supply unit and that are exposed on the wall surfaces of the fixed unit and the movable unit are not exposed, and the appearance can be improved. Further, rust can be prevented from being generated on the wall surface covered with the flexible portion.

  According to the third aspect, when the movable section moves to a position where the energy supply section is exposed, the uneven shape of the flexible section provided on the fixed section and the uneven shape of the flexible section provided on the movable section are changed. They are elastically deformed and fitted to each other. That is, the movable section can be held at a position where the energy supply section is exposed by the concave and convex fitting of the flexible section of the fixed section and the flexible section of the movable section. In the above-described conventional technology, only the clip tip locking portion 136 is deformed. However, in the present invention, both the flexible portions of the fixed portion and the movable portion are deformed and fitted to each other, and therefore, compared with the conventional technology. The amount of deformation of the flexible part of the movable part can be suppressed. Thereby, the durability of the flexible part of the movable part can be increased.

  According to the fourth aspect, the fixed portion or the flexible portion of the movable portion has a shape that covers a connection portion between the fixed portion and the movable portion. For this reason, for example, when washing a vehicle using a high-pressure washing machine, even if the sprayed water or detergent enters the inlet box assembly through a gap around the movable part, the water or detergent is not removed from the fixed part and the movable part. Can be prevented from adhering to the connecting portion. Thereby, it is possible to suppress the rust of the metal connecting portion.

  According to the fifth aspect, the flexible portion is made of a resin member.
