シール部材を配設し、フィラーチューブの下端開口部に
、該開口を開閉する開閉蓋を、タンク内側方向にのみ開
くように、かつタンク外側方向に付勢して装着したこと
を特徴としている。The present invention has a structure in which a cap is detachably attached to the upper end of the filler tube, and a sealing member is disposed between the lower surface of the flange of the cap and the upper opening edge of the filler tube, and the lower end of the filler tube is provided with a sealing member. It is characterized in that an opening/closing lid for opening and closing the opening is attached to the opening so that it opens only toward the inside of the tank and is biased toward the outside of the tank.

ラーチューブの下端開口縁部に内側から当接しているの
で、燃料がフィラーチューブ内に侵入することはなく、
従ってシール部材に燃料がかかることはないので、それ
だけシール部材の耐久性を向上できる。According to the cap mounting structure according to the present invention, since the opening/closing lid contacts the lower opening edge of the filler tube from the inside, fuel does not enter the filler tube.
Therefore, since the seal member is not exposed to fuel, the durability of the seal member can be improved accordingly.
また、給油する場合は、キャップををり外し、給油ガン
をタンク内に挿入すれば、これにより開閉蓋はタンク内
方に開かれるので、開閉蓋が給油の支障になることはな
く、従来通り容易に給油できる。In addition, when refueling, simply remove the cap and insert the refueling gun into the tank, and the opening/closing lid will open inward to the tank, so the opening/closing lid will not interfere with refueling and will remain the same as before. Easy to refuel.
以下、本発明の実施例を図について説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

ーブ３の上端開口をシールしている。The filler tube 3 is formed by bending the upper end of a cylindrical member inward to form a seal portion 3a, and the body portion 4a of the cap 4 is inserted into the seal portion a.
A locking piece 4b provided on the body portion 4a is locked to the lower end surface of the seal portion 3a. As a result, the seal member 5 attached to the lower surface of the flange portion 4C of the cap 4 comes into pressure contact with the upper end surface of the seal portion 3a, thereby sealing the upper end opening of the filler tube 3.

Ｔの上面に貼設されたシールプレート１０が上記開口６
ａの周縁に圧接し、該開口６ａをシールしている。A dish-shaped bottom plate 6 is hermetically fixed to the lower end opening of the filler tube 3. A circular opening 6a formed in the center of the bottom plate 6 has an opening/closing lid 7 for opening and closing it.
is pivotally supported by a support pin 8 so as to be freely openable and closable, and a biasing spring 9 is attached to the support bottle 8 to bias the opening/closing lid 7 in the closing direction (towards the outside of the tank). As a result, the opening/closing I
A seal plate 10 attached to the upper surface of T is attached to the opening 6.
The opening 6a is sealed by pressing against the periphery of the opening 6a.

材５の寿命を向上できる。In this case, the opening 6a of the bottom plate 6 at the lower end of the filler tube 3 is closed by the opening/closing M7, so even if the fuel splashes during driving, this fuel will not enter the filler tube 3. Since fuel does not come into contact with the seal member 5 of the cap 4, the life of the seal member 5 can be improved.
