The detailed description of this part will be omitted.

A fuel pipe 1 connected to a fuel tank (not shown) is installed inside the fuel inlet 10 formed to have a predetermined space in the body of the vehicle, and a fuel cap 30 is formed at the end of the fuel pipe 1. Is mounted, the fuel inlet 10 is opened and closed by the filler door 40 rotatably installed in the body, the filler door 40 is formed with a rod 50 extending to have a long length toward the fuel cap 30 Mounted to allow rotation about the axis centerline.

The fuel cap 30 has a rod inserting hole 32 formed in the upper portion of the rod 50 so that the lower portion of the rod 50 can be inserted into the upper center portion, as shown in more detail in FIG. 3. The bush 34 is fixedly installed with an inner diameter of a size slightly larger than the outer diameter of the rod 50.

In addition, two ball bearings 36 are disposed inside the rod insertion hole 32 at predetermined intervals, and the ball bearings 36 are upwardly moved by a biasing member 38 formed of an elastic coil spring or the like. Be biased. In addition, the inner side of the rod insertion opening 32 in which the ball bearing 36 is disposed is inclined so that its width becomes larger toward the bottom.

The coupling structure of the pillar door 40 and the rod 50 is shown in more detail in FIG. 4, and the filler door 40 has a through hole 42 formed therethrough so that the rod 50 is rotatably received. The rod 50 inserted into the through hole 42 is provided with a return spring 44 to provide a rotational force to rotate the rod 50 in a predetermined direction.

In addition, the rod 50 has a disk-shaped outer plate 52 positioned outside the pillar door 40, that is, the upper portion of the drawing, and approximately inside the pillar door 40, that is, the lower portion of the drawing. The inner rotating plate 54 in the shape of a disc is integrally formed. In addition, the rod 50 is provided with a rotary lever 56 that can apply a rotational force to the outer end of the pillar door 40, that is, the upper end as shown in the figure.

FIG. 5 is a detailed view of the portion viewed from A-A of FIG. 4, showing that the rod 50 of the portion extending inwardly of the pillar door 40 has approximately elliptical cross sections having different widths in the vertical direction.

In addition, the inner rotating plate 54 is cut at a predetermined angle, for example, about 90 °, and the stopper 46 is positioned at the cut-out portion, and the stopper 46 is fixed to the filler door 40. .

At this time, when the ball bearing 36 is raised to the lower end of the bush 34 in contact with the inside of the rod insertion hole 32, the distance between the ball bearing 36 is the width of the rod 50 It is formed to be smaller than a portion having a large size a (hereinafter referred to as 'long width') and larger than a portion having a smaller size b (hereinafter referred to as 'short width').

In addition, in the present invention, the rod 50 is described as having an elliptical cross section, but may have a rectangular cross section having short sides and long sides of different sizes.

The operation of the present invention having the above configuration will be described.

First, an initial state in which no external force is applied to the rotary lever 56 will be described.
