ク8の気密液密を保つ。FIG. 1 shows an example of a conventional fuel tank cap. The cap 1 has two claws formed by bending the lower end of an annular backing 3 and an inner cylinder 4 provided on the inner surface of a lid body 2 outward. 5 and 5 are attached to the fuel tank 8 by sandwiching the top and bottom of the cam wall 12 formed by changing the depth of the filler neck 7 that forms the tank's inlet 6, and the banking 3 is attached to the top surface of the filler neck 1. The tank 8 is kept airtight and liquid-tight by being crimped to the tank 8.
図中9は輪状バンキング3をフィラーネック1の頂部に
弾接させる輪状板ばねである。In the figure, reference numeral 9 denotes a ring-shaped leaf spring that brings the ring-shaped banking 3 into elastic contact with the top of the filler neck 1.
外気導入用の吸入弁装置等は図示を省略しである。The intake valve device for introducing outside air and the like are not shown.
このようにタンク8は完全密閉されるものであるから、
夏期等のように外気温度が高くなると燃料の蒸発により
タンク内圧力が大気圧よりも高くなる。Since the tank 8 is completely sealed in this way,
When the outside temperature rises, such as during summer, the pressure inside the tank becomes higher than atmospheric pressure due to fuel evaporation.
この圧力状態の下でキャンプ1を取外すため、把手10

are provided in two stages with different phases, and the intermediate claws 5a, 5a
Even if the cap 1 matches the notches 11, 11, the claw 5b at the tip gets caught on the cam wall 12 of the filler neck 7, preventing the cap 1 from being blown off.
しかしながら爪5aと切欠き11との間に大きな隙間が
形成されるため、そこから燃料の飛散を防止することが
できなかった。However, since a large gap was formed between the claw 5a and the notch 11, it was not possible to prevent fuel from scattering from there.
また従来は第5図に示すように蓋体2の外フランジ2a

気密、液密状態に装着される(第7図)。With this configuration, when attaching the cap 1 to the filler neck 1, the inner cylinder 4, claws 5a, and sb are connected to the inlet 6.
As it is pushed in, the lower end of the cylindrical portion 15a of the guard tube 15 first comes into contact with the banking 14 and stops (Fig. 6). From then on, only the camp 1 is pushed in while sliding on the guard tube 15, creating an airtight and liquid tight state. (Figure 7).
従ってキャップ1の装着操作時にガード筒15は少しも
邪魔にならない。Therefore, the guard tube 15 does not get in the way at all during the operation of attaching the cap 1.
キャップ1の取外し操作は装着操作と逆に行なえばよい
。The operation for removing the cap 1 may be performed in the reverse order of the operation for attaching it.
この際ガード筒15がフィラーネック7を大きく覆って
いる力)ら、同筒4とフィラーネック7との間を通り抜

。Although the presence of the guard cylinder 15 can prevent fuel from scattering, as shown in Figs. By forming a bulge 18.18 having the same outer diameter as the outer peripheral surface of the inner cylinder 4 and engaging with the notch 16, and closing the notches 16, 16, scattering of the internal fuel can be further prevented. Can be done.
なお、本考案のガード筒15は第1図に示す爪を一段し
か設けていないキャンプに装着しても同様の効果を有す
ること勿論である。It goes without saying that the guard tube 15 of the present invention will have the same effect even if it is installed in a camp that has only one level of claws as shown in FIG.
またガード筒15は蓋体2の外側に設けても良く、更に
周知のスライド機構を設計条件に応じて選択適用してガ
ード筒15をキャンプ1に縦動自在に装着してもよい。Further, the guard tube 15 may be provided on the outside of the lid body 2, and the guard tube 15 may be attached to the camp 1 so as to be vertically movable by selectively applying a well-known slide mechanism according to design conditions.
