In the figure, L indicates the distance from the bottom of the bottom 11a to the bottom of the grounding portion 12a. Further, in FIG. 1, the grounding portion 12a projects downward from the bottom portion 11a, but the grounding portion 12a may be provided on the same surface as the bottom portion 11a. Further, the outer peripheral portion of the flange portion 12 has a wavy shape, and a grip portion 12b is formed. Grip part 1
The lowermost end 12c of 2b is arranged above the grounding portion 12a.

First, when lubricating the empty hermetic oil tank, the hermetic oil tank is pulled out of the oil combustor, turned over once, and the groove 11b of the mouth opening / closing tool 10 is provided on the lubrication mouth mouth 3 as shown in FIG. Positioning is performed so as to be fitted with 3a, and then inserted. The projection 3a and the groove 11b serve as a rotation stopper for rotating the refueling mouthpiece 3, and when the mouthpiece opening / closing tool 10 is turned, the refueling mouthpiece 3 rotates integrally with the mouthpiece opening / closing tool 10.

う効果を発揮する。Also, since the inner periphery of the cap portion 11 of the mouth opening / closing tool 10 and the outer periphery of the fuel filler mouth 3 are slightly press-fitted, it is only necessary to eliminate the backlash in the radial direction when inserted. Even when the handle 5 of the airtight oil tank 1 is held upside down, it does not easily fall off.
Furthermore, even when the degree of press-fitting is increased due to variations in the dimensions of the cap portion 11 and the fuel filler cap 3 at the time of manufacture, the side wall itself is deformed outward by the effect of the split groove 11c provided on the side wall of the cap portion 11, so that it is easy. It can be inserted into The end face 11d of the opening of the cap portion 11 is a fuel filler base 3
Since it is extended so as to abut on the base flange 3b provided in the above, the movement in the thrust direction can also be prevented. Then, as shown in FIG.
This has the effect of preventing the tank from wobbling when the part is lowered.

でき、反転動作がし易くなる。Further, since the flange portion 12 is formed, when the hermetic oil tank 1 is transported, the handle 5 is held and the oil supply mouthpiece 3 of the hermetic oil tank 1 is directed downward (in the state in which the hermetic oil tank is being carried). As it is possible to temporarily stand alone, both hands can be used freely for the reversing operation of the hermetic oil tank 1. For example, a heavy hermetic oil tank can be handled with both hands, and the reversing operation becomes easier.

いという効果がある。Further, by providing a grounding portion 12a protruding further below the outer peripheral portion of the flange portion on the inner periphery than the outer peripheral surface of the large-diameter flange portion 12, the fuel filler base 3 is temporarily lowered to be self-standing. In this case, even if the grounding portion 12a is dirty, there is an effect that the touched portion of the base opening / closing tool is not actually soiled.

It has a cap portion with a groove-shaped detent, one is opened, the other is closed by the bottom surface, and a flange portion integrally formed with the cap portion is provided near the bottom surface, so that the fuel supply mouthpiece is opened and closed In this case, the force applied to the outer periphery of the flange is directly transmitted to the cap portion, and there is an effect that the opening and closing operation can be performed reliably. In addition, when transporting the airtight oil tank, the airtight oil tank can be temporarily self-standing with the filler cap facing downward.
Both hands can be used freely. For example, when handling a heavy airtight oil tank, it can be handled with both hands.
