A non-return valve includes a main tube to be externally inserted into and joined to a fuel filling pipe, and a valve element to be provided on a downstream end of the main tube for allowing fuel to flow into a fuel tank and inhibiting a back flow out of the fuel tank. On an upstream side of the main tube, provided is a first inner tube including a first retaining portion relevant to the fuel filling pipe, an annular sealing member abutting on an inner periphery of the main tube and on an outer periphery of the fuel filling pipe, and a second inner pipe disposed more upstream than the first inner tube so as to sandwich the annular sealing member together with the first inner tube, the second inner tube including a second retaining portion relevant to the main tube.
