BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel flap stopper structure which can be opened and closed at a fuel inlet of a vehicle body.

[0002]

Fuel inlet portion of the Related Art A vehicle is generally as shown in FIG. 2, the fuel Sosa c mounted inside the opening b provided on the vehicle body outer panel a, the opening of the vehicle body outer plate a
It consists of a fuel flap d for opening and closing the b, Few
El Pipe e has its distal end through the central portion of the fuel Sosa c is projected into the fuel Sosa c, and fuel delivery gun to the fuel pipe e Remove the fuel pipe e tip of the cap to open the fuel flap d Insert the fuel and insert the fuel. When the fuel injection is completed, screw the cap into the fuel pipe e.
The fuel is injected into the fuel tank by the operation of closing the fuel flap d.

[0003] The fuel flap d is rotatably attached to a fuel saucer c by a hinge arm.
In order to hold the fuel flap d in the closed state flush with the vehicle body outer panel a without rattling,
A stopper made of an elastic material which elastically contacts the back surface of the fuel flap d must be provided (see, for example,
167730).

Stopper of the fuel flash <br/> flop Disclosed invention is to provide a conventionally configured as a separate dedicated parts were, which is a stopper which is part the dedicated so that the assembly secured to the fuel Sosa Therefore, not only is the number of parts so large that it is disadvantageous in terms of cost, but if there is a problem with the assembling accuracy of the stopper, there is a possibility that the fuel flap will rattle or leak in the closed state. However, it has a problem that it is very troublesome.

An object of the present invention is to solve the above conventional problems.

[0006]

A solution for the present invention includes a packing portion made of a fuel pipe bore of the composite resin Sosa body eg PVC in fuel Sosa configured integrally by double molding, of the Sosa body flange given from the part surface height protruding fuel flap said in the fully closed state
The stopper that makes elastic contact with the back of the fuel flap,
It is characterized by being formed by double molding together with the packing part using the same synthetic resin as the packing part.

[0007]

[Function] As described above, the stopper portion is formed by double molding together with the packing portion and is integrally formed with the fuel saucer, so that the stopper, which is an independent dedicated part, is assembled and fixed to the fuel saucer. On the other hand, it is possible to reduce the cost and the number of assembling steps, as well as to improve the accuracy of the stopper, so that there is no fear of rattling or leakage of the fuel flap, and to improve the quality of the fuel inlet. be able to.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a fuel saucer. The fuel saucer 1 is composed of a saucer body 2, a packing part 3, and a stopper part 4.

The saucer body 2 includes a bottom surface 21 and the bottom surface 2.
1 is formed integrally with a relatively hard synthetic resin material, for example, polypropylene containing glass fiber, into a dish shape including a rising surface 22 rising from the outer periphery and a flange portion 23 at the edge of the rising surface 22.

The bottom portion 21 of the saucer body 2 has a fuser.
Through hole 21a is provided at the tip of the Le pipe 7 penetrates, relatively soft at the peripheral portion of the through hole 21a to fill the gap between the peripheral edge <br/> and the outer peripheral surface of the fuel pipe 7 of the through hole 21a The packing portion 3 made of a synthetic resin material, for example, PVC, is integrally formed by double molding on the saucer body 2.

In the flange portion 23 of the saucer body 2, a plurality of holes 23a for packing attachment (usually two positions) are provided.
The packing portion 3 is connected to the back side of the saucer body 2 with a synthetic resin material (for example, PVC) of the same quality as the packing portion 3 and penetrates the hole 23a from the back side of the flange portion 23. The stopper portion 4 protruding from the front surface side of the flange portion 23 by a predetermined height is formed integrally with the packing portion 3 at the same time when the packing portion 3 is double-molded. 5
Is a continuous portion which is joined to the back side of the saucer body 2 and continuously connects the packing portion 3 and the stopper portion 4 integrally.

As described above, the packing portion 3 is attached to the saucer body 2.
And a plurality of stopper portions 4 are integrally formed by double molding together to form a fuel sourcer 1. The fuel source 1 has a flange portion 23 of the sourcer body 2 and an opening peripheral edge flange 9a of the vehicle body outer panel 9.
By being joined to the peripheral bracket 6 joined and fixed to the vehicle body and fixed by means such as screwing, it is attached to the inside of the opening of the vehicle body outer plate 9, and a concave portion serving as a fuel injection port portion is formed in the vehicle body outer plate portion. It is formed. A fuel flap 8 is rotatably attached to the fuel source 1 via a hinge arm (not shown) and opens and closes an opening of a vehicle body outer panel 9.
The fuel flap 8 is closed and locked.
The rear surface portion thereof elastically contacts the stopper portion 4 formed integrally with the fuel saucer 1 and is held in a fully closed state on the same surface as the vehicle body outer plate 9 without rattling.

In the above, a packing part 3 made of, for example, PVC is double-molded on a saucer body 2 made of , for example, polypropylene containing glass fiber to form an integral fuel saucer.
1 that constitute are conventionally employed, because the present invention is to form a stopper portion 4 at the same time the double molding of packing part 3, cost the conventional shaping dual only packing part 3 most unchanged as, than the stopper is independent dedicated part with the conventional structure of fixing with fuel Sosa 1 two pairs, it is possible to reduce the cost and assembly steps, improved stopper accuracy off
There is no danger of rattling or leakage of the fuel flap 8 and the quality can be improved.

[0015]

As described above, according to the present invention, the cost of the fuel sourcer assembly can be reduced and the number of assembly steps can be reduced with an extremely simple structure.
It can also improve the quality of the fuel inlet, and can bring a great effect in practical use.
