This is consistent with the problem to be solved mentioned in the previous section.

(Example) An example of the present invention will be described with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes the fuel tank body, which has a chevron-shaped protrusion 2 at one end of its upper side, and a ring-shaped cap 5 with an inlet/outlet 4 provided at an oblique side 3 on one side thereof is attached diagonally. .

At the entrance/exit 4, a packing ring 8 made of rubber, soft metal, etc. is fitted into an annular groove 7 provided on the lower side of the inward flange 6 of the cap 5, a guide ring 10 is placed over the packing ring 8, and a guide ring 10 is placed on top of the packing ring 8. A mounting ring 3 for a guide piece 32 (described later) between the ring 10 and the inward collar 6
1 is fitted, and a screw 11 is provided on the outer periphery of this base 5.

Reference numeral 12 denotes a fuel injection nozzle having a spout 16 at the tip of a wall portion 12b formed at an angle diagonally downward, which is slidably inserted into the inlet/outlet 4 and inserted as shown in FIG. An engagement ring 14 is provided on the outer periphery of the proximal end to contact and latch on the engagement portion 9 of the packing ring 8 within the entrance/exit port 4 when pulled out to the injection position. An air inlet/outlet pipe 15 is formed at the position, and a fuel flow path pipe 16 is formed at the same lower position. Also, when pulling out the drawer to the injection position, use the outside of the entrance 4 as the base point 1.
A refueling port 17 designated as 7a is formed in the upper part, and a tip 17b of the refilling port and an injection nozzle 1 beyond it are formed.
The wall portion 12a (described above) of 2 is formed to be thinner in the center direction, and the angle θ of the wall portion is an extension line a from the base of the fuel supply port 17 to the diagonally upper part of the fuel injection nozzle 12.
It has an angle of about 15 to 20 degrees with respect to

As shown in FIG. 3, the fuel injection nozzle 12 is provided with a shaft 18 on both sides of the position that projects outward from the nozzle 5 when pulled out to the injection position, and the inner end of the bifurcated nozzle arm 19 is attached to the shaft 18. Rotatably connected. Further, the nozzle arm 19 is provided with a small protrusion 20 at a substantially right angle on the rear side (closer to the base end) of the shaft 18, and the small protrusion 20 has an arc-shaped stopper protrusion bent at an angle of about 90 degrees. A section 21 is provided.

The connecting portion 22 at the tip of the nozzle arm 19 has a fourth
As shown in the figure, the sealing lid 24 is rotatably connected by the shaft 23. The spout 13 of the fuel injection nozzle 12 is placed close to the inside of the connecting portion 22 .

The guide ring 10 allows the fuel injection nozzle 12 to pass therethrough, and has a hole 25 formed at its edge, as shown in FIG. 5, through which the nozzle arm 19 and the stopper protrusion 21 pass. The stopper protrusion 21 passing through the hole 25 applies a pressing force to the guide ring 10 when the nozzle arm 19 is rotated as shown by the solid line in FIG.
In cooperation with the engagement ring 14, the fuel injection nozzle 12 is fixed in the injection position.

A guide piece 32 is attached to the mounting ring 31 that extends obliquely from the fuel supply port 17 into the fuel injection nozzle 12 to the base of the nozzle. The guide piece 32 is not in a straight line, and when the fuel injection nozzle 12 is pulled out to the injection position shown in FIG.
A guide bend 33 is provided on the inwardly projecting portion to bend to the right in the figure. In this embodiment, the guide piece 32 is passed through the interior of an air inlet/outlet pipe 15, and the inlet/outlet pipe 15 forms an engaging portion 34 that engages the guide piece 32 somewhat loosely.

(Operations and Effects of the Invention) In the present invention, when carrying the tank body 1, etc., the fuel injection nozzle 12 is stored in the storage position inside the entrance/exit 4 of the main body 1, and when injecting fuel, the fuel injection nozzle 12 is placed in the storage position inside the entrance/exit 4 as shown in FIG. A guide piece 32 extending to near the inner end of the storage position of the nozzle 12 is inserted into the inlet/outlet port 4 from the refueling port 7, and the guide piece 32 Instead of forming a straight line, a guide bend 33 is formed in a portion protruding into the tank body 1 from near the inner end of the fuel injection nozzle 12 at the injection position, and the fuel injection nozzle 1
2 is provided with an engaging portion 34 that freely slides and engages the guide piece 32. Therefore, unlike the case where the guide piece 32 is linear, the angle is set with respect to the horizontal plane in the storage position. , resulting in a unique oscillating motion that decreases the angle with respect to the reference at the injection location. (The chain line in Figure 1 indicates the guide piece 32.
This is an imaginary diagram of the case where is made into a straight line, and the guiding bend 33
This is for comparison with the case where . ) By this swinging motion, when pouring out fuel from the spout 13 into another fuel tank or the like, it is possible to pour out the fuel without tilting the tank body 1 too much, and it can be stored in the storage position. Since the angle can be changed sequentially when the guide piece is formed in a straight line, the fuel injection nozzle 12 does not collide with the entrance/exit port 4, and moreover, the front end 17b of the fuel supply port 17
Wall portion 1 of the fuel injection nozzle 12 from to the protruding front end
Since the guide piece 2a is formed to be gradually thinner toward the center, it is possible to prevent contact friction between the mounting front end of the guide piece 32 attached to the inlet/outlet 4 and inserted into the fuel injection nozzle 12 and the fuel injection nozzle 12. At the same time, since the engaging portion 34 slides and moves without disengaging the guide piece 32 including the guide bend 33, the rocking can be caused automatically and accurately every time. In addition, even if the fuel injection nozzle 12 is formed into a truncated conical shape, the guide piece 32 will not come off the engagement part 34, so that rotation around the axis of the fuel injection nozzle 12 will not occur. In addition, the limit of the withdrawal of the fuel injection nozzle 12 to the injection position is regulated by collision with a guide piece 32 inserted into the replenishment port 17 from the rear hole edge of the replenishment port 17 in the withdrawal direction. be able to. Furthermore, the fuel injection nozzle 12 is placed in the injection position, and the fuel supply port 17 is positioned diagonally upward at an angle that is gentler than the angle at the storage position, thereby making it possible to supply fuel to the tank body 1.
