PROBLEM TO BE SOLVED: To provide an opening/closing device for a fuel tank, which includes a connection mechanism 34 for connecting a tube 12 and a valve supporting member 30 together, which dispenses with high mechanical strength, which has a simple configuration, and which is superior in assemblability.SOLUTION: An opening/closing device 10 for a fuel tank includes: a valve supporting member 30 which is inserted into a tube body 13 of a tube 12; a flap valve mechanism 50 which opens/closes an inlet 30a of the valve supporting member 30; and a connection mechanism 34 which has a first connection part 34F for connecting the tube 12 and the valve supporting member 30 together, and a second connection part 34S. The first connection part 34F has a first pipe-side engagement part 15 and an inside connection part 35, and the second connection part 34S has a second pipe-side engagement part 16 and an outside connection part 36. The outside connection part 36, which is formed by being bent along an opening end of the tube body 13 and an exterior wall of the tube body 13, is engaged with the second pipe-side engagement part 16. |
