The inner lid body b consists of a stepped dish-shaped inner lid body b and a hat-shaped restraining member c inserted between the two.
A shallow linear-shaped recess b2 is formed in the bottom of the boss part b1 , into which a stopper piece d of a predetermined length made of leaf spring material is fitted, and the center part is secured to the inner lid by a rivet r. The stopper piece d is caulked to the bottom of the boss part b 1. Insert both ends of the stopper piece d into the notch Tb formed in the inlet flange Ta of the tank, and turn it in the direction of the arrow to open the flange Ta. By sliding the cap along the wedge-shaped slope on the lower side, the rubber packing e fitted on the outer periphery of the inner lid boss part b1 is compressed, and the cap is attached to the tank inlet in a so-called bayonet style. , and Japanese Utility Model Application Publication No. 54-72223, a cylindrical portion is integrally provided on the lower surface of the center of the lid of the cap body, and a claw member formed in the shape of an ashtray is inserted from the underside of the cylindrical portion. It is biased upward by a coil spring and accommodated.
It is known that both ends of the claw member protrude from both side openings of the cylindrical part, and the protruding ends are rotatably locked to the fuel filler opening of the tank.

の両側伸長部３ｂの上面に当接している。 Further, on the cylindrical portion 2a of the inner lid body 2, a shallow dish-shaped second plate having a horizontal flange at the upper end that engages with the stepped portion 2b is provided.
The inner lid body 5 is fitted, and the circular protrusion 5a formed at the center of the bottom wall is connected to the circular protrusion 2e at the center of the inner lid body 2.
The bead portion 5b that abuts on the top and is formed on the bottom wall periphery so as to protrude slightly downward is the stopper piece 3.
It is in contact with the upper surface of both side extension parts 3b.
このため、止め片３はその中心通孔３ｃの部分

支持されると共に両側伸長部３ｂが第２内蓋体５
のビード部５ｂに接して上方から支持されて水平
を保持し、その両側部はそれぞれ下方に傾動自在
になされている。 Therefore, the center through hole 3c of the stopper piece 3 is supported from below by contacting the upper end of the hemispherical surface portion 2d' of the inner lid body, and the both side extension portions 3b are supported by the second inner lid body 5.
It is supported from above in contact with the bead portion 5b to maintain its horizontal position, and its both sides are tiltable downward.
更に、第２内蓋体５の底壁と外蓋体１の上壁と
の間には帽子状の抑止筒６が配設され、その下端
周縁は第２内蓋体５のビード部５ｂを上方から押
えている。 Furthermore, a cap-shaped restraining cylinder 6 is disposed between the bottom wall of the second inner lid body 5 and the upper wall of the outer lid body 1, and the lower end peripheral edge of the cap-shaped restraining cylinder 6 touches the bead portion 5b of the second inner lid body 5. It's being pressed down from above.
そして、７は内蓋体２の段部２ｂの下側に位置
するように筒部２ａに嵌挿されたパツキングであ
る。 Reference numeral 7 denotes a packing fitted into the cylindrical portion 2a so as to be positioned below the stepped portion 2b of the inner lid body 2.
そこで、使用に当たつて、外蓋体１を保持して

を圧縮し、これに所要のシール圧を与えてキヤツ
プ本体はタンクの注入口部に装着される。 Therefore, when using the outer cover 1, hold the outer cover 1 and insert the extensions 3b on both sides of the stopper piece 3 into the notches Tb formed in the inlet flange Ta of the tank as described above, and then open the outer cover 1. When rotated in a predetermined direction, both sides of the stopper piece 3 from the disk portion 3a to the extension portion 3b bend as shown by the dotted line in Figure 5 and form a flange.
It slides along the wedge-shaped slope on the lower side of Ta, and is packed by the step 2b of the inner lid body 2 and the flange Ta.
After compressing the cap and applying the necessary sealing pressure, the cap body is attached to the inlet of the tank.
この場合、止め片３は内蓋体２中央の半球面部

シール圧を与えてキヤツプを安定してタンクの注
入口部に装着させる。 In this case, the stopper piece 3 is simply placed on the hemispherical surface 2d' at the center of the inner lid body 2 and has no fixing relationship, so it is easy to deform downward and the span is larger than when it is fixed with rivets. In addition, the shape of the stopper piece 3 has more freedom in design, so the spring constant can be made smaller than conventional products, giving sufficient sealing pressure to the packing and stably attaching the cap to the tank's inlet. .
また、この状態で外蓋体１を前とは逆に回動
し、止め片３の両側伸長部３ｂを注入口フランジ
Taの切欠Tbに合せ、上方に持ち上げることによ
りキヤツプをタンクから簡単に取外すことができ
る。 Also, in this state, rotate the outer lid body 1 in the opposite direction from the front, and connect the both side extensions 3b of the stopper piece 3 to the inlet flange.
The cap can be easily removed from the tank by aligning it with the notch Tb in Ta and lifting it upwards.
なお、上述の説明では車両の燃料タンクを例に
したが、これに限らずオイルタンク、ラジエータ
などその他のタンク類にも使用しうることは勿論
である。 In addition, although the fuel tank of a vehicle was used as an example in the above description, it goes without saying that it is not limited to this and can be used for other tanks such as an oil tank and a radiator.

で外観上も良好になるなどの効果を備えている。(Effects of the Invention) As described above, in this invention, as a cap device for tanks, window holes are provided on both sides of the cylindrical portion inside the outer lid body, and the center portion of the bottom wall curves upward to form a hemispherical surface. An inner lid body with a protrusion formed at the center of its upper end is fitted, and a stop piece made of a plate spring material and having a center through hole is placed on the hemispherical surface of the inner lid body, and the center through hole portion is attached to the inner lid body. Since it was loosely fitted to the protrusion and placed in a free state, and both sides of the cap were inserted into the window holes of the cylindrical part in a tiltable manner, the stopper piece had no fixed relationship to the cap body and could be moved downward. It is easy to bend and deform, it has a larger span than riveted products, and there is more freedom in designing the shape.The spring constant can be smaller than conventional products, and it provides sufficient sealing pressure to the packing to stabilize the cap. It can be attached to the tank's inlet, and there is no risk of stress concentration in the center, and there is no need for rivets or coil springs like in the past, and there are few parts and assembly is easy. It is suitable for mass production, and has the advantage of improving its appearance as the stopper and other mechanisms are hidden inside the inner lid.
