are tilted in the same direction about their respective pivot shafts 45 and 46, and the spring 4 attached thereto is also tilted in the same direction while being biased in the compression direction. In this case, the lengths of expansion and contraction of the two members 43 and 44 are adjusted by the sliding movement of the guide rod 43 within the guide tube 44.
注油完了後ノズル２を引抜けば蓋部３はばね４の復元力
により開口を完全に閉塞する。When the nozzle 2 is pulled out after completion of oil filling, the lid 3 completely closes the opening due to the restoring force of the spring 4.
（発明の効果〕
この発明は常態に於て栓の開口部を閉塞している蓋部３
のためにフュエルタンク内の燃料を常に密閉しておくの
で車輌走行時の燃料漏れが起ぎない。(Effects of the Invention) This invention provides a lid portion 3 that normally closes the opening of the stopper.
Therefore, the fuel in the fuel tank is always kept sealed, so there is no fuel leakage when the vehicle is running.
また、燃料の注油時には注油ノズルを即時栓開口部に挿
込むだけで注油作業を行うことができ、注油後の注油ノ
ズル引抜時には蓋部が自動的に開口部を閉塞するので栓
開口部への閉塞手段を行う必要がない。In addition, when filling fuel, you can perform the lubrication work by simply inserting the lubrication nozzle into the spigot opening, and when the lubrication nozzle is pulled out after lubrication, the lid automatically closes the opening. There is no need to perform occlusion measures.
特にこの発明の実施例の場合は更に次の特有の効果を生
ずるものである。Particularly, in the case of the embodiment of the present invention, the following unique effects are produced.
蓋の閉塞用ばねに対して伸縮自在なばね部材を設けたの
でノズル先端の急激な抑圧を原因とする蓋の開、閉時に
生ずる蓋部に対する押圧力を前記ばね部材が吸収し、蓋
部材を常に同一方向に傾動させ閉塞機能を低下させるこ
とがない。Since a telescopic spring member is provided for the closing spring of the lid, the spring member absorbs the pressing force against the lid that occurs when opening and closing the lid due to sudden compression of the nozzle tip. It is always tilted in the same direction so that the closing function is not deteriorated.
また栓の開放部にｍ１Ａを設けたので、この栓を例えば
ドラム缶などの燃料タンク内からエンジン部への給油の
場合はドラム缶内からの夾雑物を濾過して清浄油を供給
することができる。Furthermore, since m1A is provided at the opening of the stopper, when the engine is supplied with oil from the inside of a fuel tank such as a drum, the stopper can filter out impurities from the inside of the drum and supply clean oil.
その上栓の開口部に案内環を設けたのでノズルの押込が
容易であり、その上蓋部と開放口端との距離空間がある
ので他の器物による誤った蓋に対する開放が生じない。Furthermore, since a guide ring is provided at the opening of the top stopper, it is easy to push the nozzle in, and since there is a space between the top cover and the opening end, there is no possibility of accidentally opening the cover by other utensils.
更に、この発明は前記案内環の開口端にキーによらなけ
れば開閉しない保護蓋を設けることによって、更に蓋に
対する安全性を高めることができる。Further, in the present invention, by providing a protective cover at the open end of the guide ring, which cannot be opened or closed except by a key, the safety of the cover can be further improved.
