プ、Ｅは油面ゲージを示している。(Prior Art) In a fuel tank, as shown in FIGS. 1 and 2, a thin pipe B is welded to the upper surface of a tank A, and a breather pipe C is connected to this. This is because if the inside of tank A is in a sealed state, it will become negative pressure as fuel is used, and in order to prevent the fuel from flowing to the outlet, air will be replenished as fuel is used to prevent negative pressure phenomenon. It is something. In addition, when using a highly volatile fuel such as gasoline, it is also important to prevent internal expansion when the temperature rises, such as in the summer. Note that D indicates the filler cap and E indicates the oil level gauge.

In addition to providing a liquid inlet and a hole for installing an oil level gauge on the top of the tank, it is also necessary to install a breather pipe on the top of the tank.
There are problems such as high manufacturing cost, and there is also a problem in terms of installation space.

(Means for Solving Problems) The present invention is a system in which an oil level gauge is fastened to the top surface of a tank using bolts, and one of the bolts that fastens the oil level gauge is inserted into a core hole. A special bolt is used to connect the breather pipe to the core hole.

も解消することができる。(Function) Air flows into the liquid tank through the breather pipe as fuel or the like is used, and negative pressure inside the tank is prevented. In addition, the breather pipe can be connected to the tank by attaching it to the top of the tank using the above-mentioned special bolt together with the normal bolt of the oil level gauge, and there is no need to attach the breather pipe to the tank separately. It is possible to reduce the manufacturing cost and also solve the problem of mounting space.
（実施例）
液体タンク１の上面に油面計２を複数のボルト
３によつて締着する。この考案はこの油面計２を
取付けるボルト３を利用するもので、そのうちの
一つを芯孔４を有する特殊ボルト５にする。そし

連結する。７は注入口キヤツプである。(Example) An oil level gauge 2 is fastened to the upper surface of a liquid tank 1 with a plurality of bolts 3. This invention utilizes the bolts 3 for attaching the oil level gauge 2, one of which is a special bolt 5 having a core hole 4. A breather pipe 6 is connected to the upper end of this special bolt 5. 7 is an inlet cap.
しかして、油面計２液体タンク１の上面に締着

間がかからない。 Therefore, air can flow through the core hole 4 provided in one of the special bolts 5 among the bolts 3 fastened to the upper surface of the oil level gauge 2 and the liquid tank 1, and air leakage within the tank 1 can be prevented. Moreover, since the special bolt 5 is tightened with a wrench together with the other bolts 3 when attaching the oil level gauge 2 to the upper surface of the tank 1, it does not take much time to attach it.
以上説明したように、この考案は、タンクの上

減できてコストダウンができる。
As explained above, this invention, when an oil level gauge is fastened to the top of a tank with bolts, uses one of the bolts that fastens the oil level gauge as a special bolt with a core hole. Since the breather pipe is connected to the core hole, air can flow through the core hole of the special bolt to prevent air leakage inside the tank. There is no need to provide a separate pipe for air circulation on the top surface of the tank, which saves materials, eliminates troublesome welding work, etc., reduces manufacturing man-hours, and lowers costs.
