A fuel filler port closing apparatus including an opening (44) of a filler neck or an opening (211) of a nozzle guide (21) securely and reliably sealed, even when a seal packing (325) sags, bends or deflects. Sealing is realized by a flapper (3) including a rotation plate (31) which rotates and flaps, and a seal plate (32) having the seal packing (325) moving freely in an up and down direction with respect to the rotation plate (31). |
