PROBLEM TO BE SOLVED: To provide a couper capable of easily performing movement of liquid fuel with a simple constitution.SOLUTION: A coupler 1 includes a connection body 6 provided on a fuel cell 2 and a body 7 to be connected which is connected with the connection body 6. Therein, the connection body 6 and the body 7 to be connected are formed in a cylindrical shape and have first and second connection ports 26, 66 formed on one side edge parts thereof. In the first and second connection ports, first and second contour members 11, 51 which form first and second fuel channels F1, F2, and first and second air channels G1, G2 are provided. First and second valve bodies 12, 52 which are disposed in the first and second contour members 11, 51, close the first and second fuel channels F1, F2, and the first and second air channels G1, G2, then, move, thereby open the first and second fuel channels F1, F2, and the first and second air channels G1, G2 are provided. Further, first and second energization members 14, 54 which are supported on edge surfaces of the first and second valve bodies 12, 52, are arranged in the first and second contour members 11, 51 and energize the first and second valve bodies 12, 52 onto positions on which the first and second connection ports 26, 66 are closed are provided. |
