CAPLESS FUEL FILLER ASSEMBLY

A capless fuel filler assembly is attached to a distal end of a filler pipe extending from a fuel tank. The capless fuel filler assembly includes a main body, a flap valve, and a pair of stopper ribs. The main body has a fuel filler through which a nozzle of a filler gun is inserted. The flap valve is disposed in the main body such that the flap valve can be opened and closed, and the flap valve opens and closes the fuel filler. The stopper ribs project inward from an inner surface of a flow path of a liquid fuel formed in the main body. The pair of stopper ribs project inward toward each other, and regulate an insertion depth of the nozzle. The shortest distance between the pair of stopper ribs is smaller than an outer diameter of a distal end of the nozzle.
