Abstract: A channel forming member is attached to a filler neck on a nozzle insertion side where a fueling nozzle is to be inserted. The channel forming member includes a barrier section that forms an insertion flow path section for the fueling nozzle in the fuel flow path on the nozzle insertion side, while forming an annular channel surrounding the insertion flow path section so as to separate the channel from the insertion flow path section. The channel forming member further includes the following provided to the barrier section: an atmosphere communication hole for making the channel communicate with the atmosphere; a flow path communication hole for making the channel communicate with an insertion end flow path section downstream from the insertion flow path section; and a valve mechanism that prevents passage of the atmosphere through the channel in a fueling period. This contributes to reduction in introduction of the atmosphere into the fuel flow path through the channel in a fueling period.
