PROBLEM TO BE SOLVED: To provide a seal structure for a fuel tank cap having a moving member in the center thereof.SOLUTION: The cap attached to a fuel tank is attached and locked to the fuel tank in a bayonet manner. An operation member 18 for releasing the lock is supported to a base end member 10 of the cap so as to be slidable in an axial direction. A gap between the base end member 10 and the operation member 18 is sealed by a seal member 12. The seal member 12 provides a bent shape at a longitudinal section at the part thereof between the part fixed to the base end member 10 and the part fixed to the operation member.

    【課題】中央に可動部材を有する燃料タンク用キャップのシール構造を提供する。【解決手段】燃料タンクに取り付けられるキャップは、バヨネット式で燃料タンクに取り付けられてロックされる。ロックを解除する操作部材18は、キャップの基端部材10に軸線方向に摺動可能に支持される。基端部材10と操作部材18との間隙はシール部材12によってシールされる。シール部材12に於いて、基端部材10に固定された部分と操作部材に固定された部分との間の部分は、縦断面において屈曲形状を呈する。【選択図】図6
