A fuel feeding device 10 has a first shutter mechanism 20 that has a first closing member 21 to open and close a first seal opening UP1, a second shutter mechanism 30 that has a second closing member 31 to open and close a second seal opening UP2, and a coupling mechanism 40 that guides the second closing member 31 to be opened and closed in conjunction with the opening and closing action of the first closing member 21. In the process of fuel supply, when a fuel supply gun presses open the first closing member 21, the second closing member 31 moves in conjunction with the first closing member 21 via the coupling mechanism 40 to open the second seal opening UP2. In the fuel feeding device 10 for a fuel tank, the opening and closing mechanism of the closing member arranged in an inlet pipe IP is substantially free from any significant trouble.
