注入口１．１１を用いていた。However, in view of the recent demand for lighter parts, there is a tendency for this injection port to be made of resin. And to protect this from the fuel injection nozzle (made of metal),
A metal mouthpiece is attached to the opening of the injection port. A seal is required between this opening and the mouthpiece to prevent the fuel in the injection port from leaking to the outside. Furthermore, since the injection port is made of resin, static electricity is generated when the fuel rubs against it. In order to dissipate this static electricity, it was necessary to ground the base to the vehicle body. In order to satisfy such requirements, an injection port 1.11 having the following configuration has conventionally been used.

とする。In the injection port 1l having such a configuration, the opening 14 of the main body 13
Airtightness between the cap portion 13 and the cap portion 13 is ensured by an O-ring 19 mounted on the outer periphery of the tip of the aperture 14. The tip of the caulked portion 15b and the vehicle body 10 are connected to each other by a conductive wire 16 to provide grounding. For the above, please refer to Japanese Patent Application Laid-Open No. 58-56917, West German Publication DE-3027002 AI, etc. Problems to be Solved by the Invention> As mentioned above, the injection port must: ■ have airtightness between the opening and the mouthpiece, and ■ must have the mouthpiece close to the vehicle body hair to prevent static electricity from accumulating in the injection port. The following two requirements must be met: In order to satisfy the requirement (2), in the injection port 1 shown in FIG. 8, the main body 3 was blow-molded using the mouthpiece 5 as an insert. Therefore, it was not possible to integrate the retainer 7 with the main body 3, and the structure was such that a separate retainer was prepared and caulked to the main body 3. In addition, in order to satisfy the requirement (2), it was also necessary to bury the main body part 3 and the bypass 6. Therefore, the number of parts, especially around the opening 3, has increased and it has taken time and effort to assemble them.However, in the injection port 11 of FIG. 9, the O-ring 1 is
9 required conductor wires 16 in order to satisfy the ■requirements. Therefore, similar to the case shown in FIG. 8, there were problems in that the number of parts, especially around the opening 13, increased and it took time and effort to assemble them. <Means for Solving the Problems> The present invention is a fuel tank inlet made in view of the above-mentioned problems, and is composed of a resin cylindrical inlet that communicates with the fuel tank at one end and opens to the outside at the other end. A main body part, a protection part that is attached to an opening of the main body part and protects the inner periphery of the opening, and a caulked part that is folded back outward from the protection part and crimped to the outer periphery of the opening. An injection port comprising a mouthpiece and a retainer that integrally rises from the outer periphery of the opening and is fixed to the vehicle body, and between the caulked part and the outer peripheral surface of the opening, One edge of a sheet-like gasket made of a conductive elastomer material is sandwiched around the entire circumference, and the other edge of the gasket is sandwiched between the retainer and the vehicle body.

The nozzle following part 57 has its tip bulging part 58 sandwiched between the nozzle 29 and the retainer 59,
Move according to the nozzle 29. As a result, the cylindrical portion 53 also moves together with the seal portion 27. Therefore,
When the nozzle 29 is inserted, the seal portion 27 that had been riding on the guard 41 before the nozzle 29 is inserted moves to the left in the figure, and its inner periphery comes into close contact with the outer surface of the nozzle. The bushing 61 is composed of a dish-shaped base 63 that is attached to the tip of the reduced diameter portion 33, and an arm 65 that is inserted into a window 34 formed in the 1-it diameter portion 33. The base 63 is fixed to the cylinder 53, and when the arm 65 is pushed by a fuel cap (not shown), it moves the tube 53 to the left. Thereby, the seal portion 27 is always separated from the guard 41 with the fuel cap attached.

方向を作業者から避けるためである。In the injection port 21 having such a configuration, when the auto-stop of the nozzle 29 fails and the internal pressure of the fuel tank increases, the valve portion 77 separates from the valve seat surface 71 before the seal portion 27 expands. Therefore, between the valve seat surface 71 and the gasket 79→
Through hole 85 formed in spring seat 83 → window 3 of base part 31
4→The fuel overflows to the outside through the opening 25, and the fuel that leaks out from the through hole 85 of the spring seat 83 is transferred to the fifth
The gasket 9 passes through the groove 26 as shown by the arrow in the figure.
0 is lifted up, and the meat in the area surrounded by the slit 91 is pushed outward to flow out. That is, the part of the meat surrounded by the slit 91 serves as a fuel relief valve. Therefore, a general check valve can be provided in place of the slit 91. Note that the degree of opening of the portion surrounded by the slit 91 is preferably designed such that the included angle α with respect to the axis of the main body portion 23 is 45 degrees or more. This is to avoid the direction of fuel flow from the operator.
また、燃料流出方向が広がるので、異常事態の発見も早
