This type of fuel tank cap with a seal gasket is installed at a location where it is easy to refuel at a gas station or the like, and is designed to prevent the fuel in the tank from leaking to the outside due to vibrations during driving. Normally, the space between the filler neck connected to the fuel tank and the cap is sealed with an O-ring to ensure airtightness from the outside, but further safety measures are desired in consideration of accidents and the like.
従来、この種のシールパツキン付き燃料タンク
用キヤツプとしては、例えば、第４図に示すもの
が知られており、１は燃料タンク用キヤツプを表

６が取り付けられている。 This fuel tank cap 1 is composed of a disc-shaped head 2 and a cylindrical part 3 integrally connected to the head 2 and having a threaded part 4 on its outer periphery. An O-ring 6 made of an elastic member such as rubber is attached to the root portion 5 at the boundary between the head 2 and the cylindrical portion 3.

のを阻止することができる。 According to the fuel tank cap 1 to which the O-ring 6 is attached in this way, as shown in FIG. It can be fixed by screwing together the screw portion 4 provided at 3. With this, the O-ring 6 is connected to the tip 7a of the filler neck 7 and the fuel tank cap 1.
The head 2 is elastically deformed by applying pressure from the lower surface 2a and the base 5, and the fuel in the fuel tank is dislodged between the threaded parts 4 and 8 due to the vibration or rocking of the car, for example. 〓It can prevent leakage to the outside through the gap.

However, in the fuel tank cap 1 equipped with the conventional O-ring 6 as shown in FIG. 4, if a strong impact force is applied to the fuel tank cap 1 due to an accident or the like, and a force such as F is applied, for example, Since the fuel tank cap 1 is pressed and bent, O-
There is a gap around the ring 6, which deteriorates the sealing performance and may cause fuel leakage. Especially in cold weather, O
- Since the shape recovery response of the ring 6 is poor, the sealing performance is significantly deteriorated, and there is a risk of fuel leakage.
そこで、例えば特公昭57−40028号公報には、

In order to improve sealing performance, instead of an O-ring, an annular groove opened radially outward is provided by an axially inner lip, an axially outer lip, and a joint web disposed around the cap. An annular seal ring has been proposed in which the inner lip is formed with a circumferentially and outwardly extending bead on its radially outer edge.

Since the groove is easy to open, pressure can easily escape, and the force F as described above
When it was applied, the sealing force around the area was weak and the sealing performance was poor.

In the present invention, the seal packing has a hollow interior, and an annular protrusion provided around the entire circumference of the root portion between the head and the cylindrical portion is fitted into the opening,
A pair of annular folded protrusions are brought into airtight contact along the wall surface of the annular protrusion, and a curved portion extending from each pair of annular folded protrusions to an outer surface of the seal packing is brought into close contact with the seal packing holding portion. Since the seal gasket is attached to the fuel tank cap, the interior of the seal gasket is closed when the seal gasket is attached to the annular projection. When the fuel tank cap is attached to the filler neck in this state, the seal packing deforms into a flat shape using the annular protrusion as a fixing point, and as a result of this deformation, the air inside is compressed, internal pressure increases, and elastic force is applied. occurs, and an elastic body such as an automobile tire can be formed. In addition, when pressure is applied to this elastic body, the pair of annular folded protrusions tightens, improving sealing performance.
It has the ability to follow fluctuations in the gap between the fuel tank cap and the filler neck, so even if a shock is applied and a gap occurs between the fuel tank cap and the filler neck, the
Can maintain sealing performance.

シール性を保つことができる。 The fuel tank cap 10 with the annular seal packing 20 attached thereto can be rotated by rotating the threaded part 13 provided on the outer periphery of the cylindrical part 12, so that the threaded part 31 provided on the filler neck 30 of the fuel tank can be rotated. The annular seal packing 20 is compressed while being screwed together. As the fuel tank cap 10 is tightened, the annular seal gasket 20 is attached to the annular protrusion 15 with its interior made hollow, so the annular seal gasket 20 uses the annular protrusion 15 as a fixing point. It deforms into a flattened shape, and with this deformation, the air inside is compressed, internal pressure increases, and elastic force is generated, making it possible to form an elastic body like an automobile tire. As a result, the gap between the fuel tank cap 10 and the filler neck 30 is filled. Further, when pressure is applied to the annular seal bag 20, the pair of annular folding protrusions 23, 23 acts in a direction to tighten, and each pair of annular folding protrusions 23, 2
3 to the outer surface of the seal packing 20, the curved portions 24, 24 extend from the seal packing holding portion 16,
The fuel tank cap 10 and filler neck 3 are firmly adhered to each other, improving sealing performance, and are able to follow fluctuations between the two, so even if an impact is applied, the fuel tank cap 10 and filler neck
Even if a situation occurs where a gap occurs between 0 and 0,
Can maintain sealing performance.

易に追従して、シール性を損なうことがない。 As described above, according to this embodiment, when the annular seal packing 20 is attached to the annular protrusion 15 of the fuel tank cap 10, air is sealed inside the annular seal packing 20.
The air within 0 acts as an elastic member, resulting in
It becomes possible to maintain a constant pressure, and when the fuel tank cap 10 is attached to the filler neck 30, the gap can be reliably filled. Moreover, the annular seal packing 20 has curved portions 24, 24 extending from the pair of annular folded protrusions 23, 23 on the inner side to the outer surface of the seal packing 20.
A curved seal packing holding portion 1 formed on both sides of an annular protrusion 15 of a fuel tank cap 10.
6, it is possible to make close contact with the seal packing holding parts 16, 16, preventing air from leaking from that part, and even if an impact is applied, for example due to a collision, the force will be reduced. can be easily followed without compromising sealing performance.

As described above, according to the present invention, an air chamber is formed inside the annular seal packing from the time it is attached to the fuel tank cap, and the attachment part is connected to the annular fold formed in the annular seal packing. Since it is formed by surface contact between the protrusion and the annular protrusion, the internal pressure increases due to the tightening force when attaching the fuel tank cap to the filler neck, ensuring a secure connection between the fuel tank cap and the filler neck. can be filled in. However, since this state can be maintained, even if a gap occurs between the fuel tank cap and the filler neck due to deformation due to external impact, the outer shape of the annular seal packing will deform accordingly. This makes it possible to fill the gap between the two and prevent fuel leakage.
