PROBLEM TO BE SOLVED: To provide a small-sized valve gear for a fuel tank capable of sensing a full-tank condition more than once with a less number of components. SOLUTION: A float valve element 70 to open and close a gas passage 88 is coupled with a coupling shaft 62 installed at a diaphragm 60, and it is possible to make additional fuel supply certainly using only one unit of this float valve element 70 by moving the float valve element 70 in a single piece with the diaphragm 60 and the coupling shaft 62, or by solely moving the float valve element 70 using buoyancy with respect to the diaphragm 60 and the coupling shaft 62. This can be done with only one float valve element 70, so that it is possible to lessen the outside contour of the valve gear 22 for fuel tank using a simple construction.
