［］工費の増電を令嬢なくさｎていた。This cypress filler tube needs to have a diameter of about 48 to 53 mm near the fuel injection port due to various laws and regulations related to the structure, fuel system, etc. of the #IJ car. Therefore, when the filler tube is formed from a metal tube, conventionally, as shown in Figure 1, a blank tube A is used that spans the entire length of the filler tube L and has the same diameter as the fuel inlet 2, and is bent as appropriate. It was formed in the same way. However, the diameter of the filler tube 1 and fuel injection port 2 needs to be increased due to the reasons mentioned above.
f) The part connected to the fuel tank (lower end in the figure) only needs to pass through the fuel injection port 2.
Even if the diameter is smaller than that of VC, the function can be sufficiently achieved. Therefore, as mentioned above, the filler tube 1 was formed using a large diameter σ) woodwinder.

ために高度の枝肉な要し、やはり製品のコストアップを
智いらｎ、１てしまうという問題点があった。Therefore, in recent years, as shown in Fig. 2, the fuel injection port 2 and a smaller diameter blank tube B (for example, 4λ7mφ) are used, and the vicinity of the fuel injection port 2 is expanded in an I-line shape to achieve the desired purpose. Filler tube la designed to obtain the diameter of fuel injection port 2a
There is. However, in this method of enlarging the fuel injection port 2a portion 1i in an eleven-dimensional shape, the pipe expansion ratio expressed as the ratio of the diameter of the fuel injection port 2a after expansion to the diameter of the raw pipe B is generally about 1.3 to 1. 1.4 degrees of darkness is considered the limit for cold/10 machining. This indicates a limit to the ability to reduce the diameter of the raw pipe and achieve the effects of reducing material costs, processing costs, and vehicle volume. Therefore, these effective W! It can be seen that in order to increase the pipe expansion ratio, the pipe expansion ratio can be increased. Therefore, as a means of increasing the tube expansion rate limit, as shown in FIG. Connected parts 4 and 2
minute III L, the fuel inlet part 1 is the fuel inlet 2b
By using a raw pipe with the same diameter as the predetermined diameter of the aW!
The diameter of the raw tube C used for the continuation portion 4 is further reduced (for example,
3 L8111φ) is being considered. However, with such a two-part filler tube 1bK, the processing cost for forming each part 3゜4 and the processing cost for fixing the two divided parts are high. However, in order to satisfy predetermined quality such as airtightness of the fixed part, a high degree of carcass is required, which inevitably increases the cost of the product.
本発明はかかる従来のｌｆｌ魂点に鑑みて、フィラ終的

Using the material, set the length of the inclined part to LYFJ120, expand the pipe into a 111 inch shape, and set the diameter of the fuel injection port 11 at the crossroads to the predetermined diameter of 48 holes to 53 mm as described above. It's Nishide. By the way, in order to expand the pipe in an inclined manner near the fuel injection hole 11'1, as shown in FIG.
The pipe is expanded by inserting it from the 11th direction of the fuel injection port of the cumulative pipe, but as the raw pipe is gradually expanded, Since the tube expansion rate is small and the insertion of the punch P during expansion becomes easy, the final tube expansion rate can be greatly increased. As shown in FIG.
A 7 flange 13 disposed around the outer periphery of the fuel injection port 11 is fixed to the lower end of the fuel injection port 2 by spot welding or the like. This 7 flange 13 is attached to a body panel (not shown), such as a rear fender where a fuel injection opening is formed, and the connecting portion 14 below the slanted tube expansion portion passes through the rear fender's ll1111iil. Connected to a fuel tank not shown.

The ratio of the diameter of the fuel injection port 11, that is, the expansion ratio is approximately 1.6.
A large value of about 1.8 is obtained.

Cut the filler tube to the specified length for the fuel tank [8 consecutive bends to the specified shape. Although it is necessary, this bending knife cutter 8! (Benders, etc.) are also divided according to the stiffness of the material to be υO cut (S division is more cost-effective, so the adjustment is done by appropriate noise). 3 (C) What is exact size cutting time? After bending the raw pipe that has been cut to the specified dimensions, it is finally cut to the specified dimensions using force, tumbles, etc. The thickness of the material to be cut is determined by the amount of time required for cutting. , is determined by the outer diameter.Also, when attaching the filler tube 10 to the bundle, fix the 7 langes 13 through screws etc. from the grooves 11 of the car body such as fenders. The electric body (Nel's sadness is narrow)
Compared to the conventional case where the area near the fuel inlet (1) has the same property, it is possible to secure a wider space by making it slanted (1) as in this embodiment, making it easier to attach the bulb. sex! It can be raised.

るという−れた効果を奏する。0 As explained above, in the filler tube of the present invention, the vicinity of the material injection port is gradually expanded obliquely toward the inlet direction, and the length of this inclined portion is set to the length of the raw tube. By setting the diameter sufficiently larger than the general diameter, the pipe expansion limit can be increased. Therefore, in order to obtain the desired fuel injection port diameter, it can be formed by integral molding using a small diameter raw pipe.
) and reduce the 7JO construction cost for processing the filler tube, reducing the cost of the product.
Further, it is also possible to reduce the vehicle weight by m. Another advantage is that by slanting the area near the fuel injection port S, a large mounting space can be secured and the installation workability can be improved.
