To restrict sudden closing of a lid when it is operated to be closed, while ensuring a large torque for the lid in the maximum open position.SOLUTION: A lid urging structure has a spring body 16 that urges the lid 5 by its being provided such that one end 16a of a spring is connected to the supply-port formation body 4 and the other end 16b of the spring is connected to the lid 5 and the most elastic deformation is exhibited in the intermediate position between the closed position of the lid 5 and the maximum open position thereof. The spring body 16 is connected to the lid 5 so as to allow a variable distance between the other end 16b of the spring and the rotation center of the lid 5. The distance is constant when the lid 5 is located between the closed position and the intermediate position, increases while the lid moves from the intermediate position to the maximum open position, and is maximum when the lid is in the maximum open position.SELECTED DRAWING: Figure 4

    【課題】リッドに対するトルクを、最大開放位置において大きく確保しながら、リッドの閉じ操作時にはリッドの急閉をできるだけ生じさせないようにする。【解決手段】バネ一端16aを前記補給口形成体4に連係させ、バネ他端16bを前記リッド5に連係させると共に、前記リッド5の前記閉じ位置と最大開放位置との間の中間位置において最も弾性変形されるように備えられて前記リッド5を付勢するバネ体16を有している。前記バネ体16は前記バネ他端16bとリッド5の回動中心との間の距離を可変するように前記リッド5に連係されており、前記距離が前記リッド5が前記閉じ位置と前記中間位置とにあるときは一定で、前記中間位置から前記最大開放位置に向かう過程で増加して前記最大開放位置にあるときに最大になるようにしてなる。【選択図】図4
