Abstract
The float valve of the invention comprises: a case 11, float 15, valve 16 capable of closing a efflux channel 18 of air A, and ball 17 for supporting a motion of closing the float 15. A through-hole 13a for communicating air provided on the side wall 13 of the case is open at a position, the level of which is the same as that of a fuel level LF in the fuel tank in the case of appropriately filling up the fuel tank with fuel. A float body 15a of the float 15 is disposed on a plate portion 12a on the bottom wall 12 of the case at a position higher than a through-hole 13a on the side wall 13 of the case. Thereby, air can be positively discharged from the fuel tank until the fuel level reaches a position at which the fuel tank is filled up with fuel in the case of refueling, so that fuel can be smoothly fed into the fuel tank.
