【Example】

 Next, embodiments of the first and second inventions will be described with reference to the drawings.

(Structure of the First Embodiment) As shown in FIGS. 1 to 6, the oil filler structure of the first embodiment has an inlet box 1 fixed to an outer panel OP having an opening O 2 for the oil filler. And a fuel inlet box 4 composed of a hinge 2 integrally formed with one end of the inlet box 1 and a fuel lid 3 integrally formed with the inlet box 1 and locked to the hinge 2, and when fixing the fuel inlet box 4 to the outer panel OP. A rubber packing 5 is inserted between the inlet box 1 and the outer panel OP.

The inlet box 1 is made of synthetic resin and has a substantially rectangular annular flange portion 11, a quadrangular pyramid taper portion 12, an opening portion 13 formed at the tip of the taper portion 12, and a flange portion. Clamps 14A to 14D which are formed at four upper and lower positions of 11 and which engage with the four fixing holes FH of the outer panel OP, and a cushion rubber portion which will be described later and are formed near the upper and lower clamps 14B and 14C on the right side in FIG. Two through-holes 15A, 15B for use with a lock pin 16 integrally formed with a tapered portion 12 for locking the fuel lid 3 described later.

The hinge 2 is formed of synthetic resin that is integral with the inlet box 1, and has a first portion 21 formed perpendicularly to the left side portion of the flange portion 11 of the inlet box 1 in FIG. 2, and the first portion 21. Similarly, a second portion 22 formed at one end of a fuel lid, which will be described later, and a thin hinge portion 23 formed between the first portion 21 and the second portion 22 and the first and second portions 21 and 22. And a triangular reinforcing rib 24 which is formed horizontally above and below and also serves as a stopper for the fuel lid.

The fuel lid 3 is composed of a substantially rectangular plate member 30 formed of synthetic resin integrally with the inlet box 1, and the second portion 22 of the hinge 2 is integrally formed at one end of the inner wall 31. A cap hanger 32 for locking a fuel cap (not shown) integrally formed on the upper portion of 31 and a hook 33 for engaging the lock pin 16 of the inlet box 1 integrally formed on the other end of the inner wall 31. It consists of and.

The rubber packing 5 is a substantially rectangular annular body 50, and through holes 51A to 51D for the cramps 14A to 14D of the inlet box 1 are formed at the four corners thereof, and cone-shaped cushions are provided on the upper and lower right sides in FIG. The rubber portions 52A and 52B are formed to project.

(Operation of First Embodiment) Prior to assembling the fuel filler structure of the first embodiment to the outer panel OP, the rubber packing 5 which is two members is preliminarily attached to the clamp 14A to the flange portion 11 of the fuel inlet box 4. 14D is inserted into the through holes 51A to 51D and locked to form one member, and then the clamps 14A to 14D of the flange portion 11 of the fuel inlet box 4 are formed around the opening O of the outer panel OP. The assembly is completed by inserting and fixing in the fixed holes F H.

When the fuel lid 3 is closed, the lock pin 16 formed integrally with the tapered portion 12 of the inlet box 1 and the hook 33 of the fuel lid 3 are engaged and locked, and the cushion rubber portions 52A and 52B of the rubber packing 5 are , Elastically deforms as shown in FIG. 6 to elastically support the fuel lid 3.

When the fuel lid 3 is opened, when the hook 33 and the lock pin 16 are released from the locked state, the fuel lid 3 rotates about the thin hinge portion 23 of the hinge 2 as a fulcrum as shown in FIG. However, as shown in FIG. 4, the side end of the fuel lid 3 comes into contact with the reinforcing rib 24 as a stopper of the hinge 2 to limit the rotational opening degree.

(Effects of the First Embodiment) In the fuel filler structure of the first embodiment having the above-described operation, the rubber inlet 5 is attached in advance and the fuel inlet box 4 which is a member is inserted into the fixing hole of the outer panel OP. Since the assembling is completed if the two are firmly fixed, the number of assembling steps can be minimized as compared with the conventional method, and the workability in the production line can be improved.

Moreover, the structure of the first embodiment is composed of only two members, for example, the injection molded one-piece fuel inlet box 4 and the rubber packing 5, and the structure is simple as compared with the conventional one, and the number of parts is greatly increased. Since it has been reduced to 1, it has the effect of realizing cost reduction.

In addition, the structure of the first embodiment has an effect that the conventional body sealer can be eliminated by using the rubber packing 5, and the rust prevention reliability and appearance can be improved.

Further, in the structure of the first embodiment, the cap hanger 32 is formed on the fuel lid 3 to lock the fuel cap, and the reinforcing ribs 24 limit the rotational opening of the fuel lid 3 to collide with the outer panel OP. There is an effect that can be avoided.

(Second Embodiment) In the oil filler structure of the second embodiment, the hinge portion 23 of the hinge 2 is thin in the first embodiment, whereas the elliptical hole 25 has the same thickness. Are arranged in a row to form a locally small portion of the cross-sectional area to form the hinge portion 23, and the other portions have the same configuration and have the same effect as the first embodiment.

The above-mentioned embodiments are merely examples for explanation, and the present invention is not limited to them, and relates to a structure which can be recognized by those skilled in the art from the description of the scope of claims for utility model. Modifications and additions are possible as long as they do not violate the technical idea.

In each of the above-described embodiments, an example in which rubber packing is used has been described. However, the entire inlet box and other fuel inlet boxes are made of a synthetic resin foam molded article and have rubber-like elasticity on the surface. If so, the rubber packing can be omitted.
