It can be held in a folded state, and the filler neck 4 can be inserted into the storage chamber 6 in this state. Therefore, it is possible to improve the fitting out. Further, if the folded lower tongue portion 14 is released, the convex portion 15 can be pulled from the outside of the vehicle (inside the accommodation chamber 6), so that the fitting out property can also be improved. (5) Since the boot 10 is an integral piece made of an elastic member, it is easy to mold at the time of manufacturing, and it is easy to be deformed at the time of fitting, so that the fitting property can be improved.
