<P>PROBLEM TO BE SOLVED: To provide a fuel tank opening-closing device that has a flap valve mechanism including an opening-closing member having a pressure regulating valve and opening and closing by being pressed by an end of a fueling nozzle, and that provides a configuration having little effect on the pressure regulating valve even when large force is received by the opening-closing member by being pressed by the end of the fueling nozzle. <P>SOLUTION: The fuel tank opening-closing device includes the flap valve mechanism 20 and an opening-closing activation mechanism 40. The opening-closing member 21 of the opening-closing activation mechanism 40 includes a valve chamber defining member 28 that has a concave opening toward a side of an insertion path 13P, a cover 24 that defines a valve chamber 28S by covering an opening of the concave, the pressure regulating valve 30 that is stored in the valve chamber 28S for adjusting pressure between the insertion path 13P and a fuel passage 11P within a preset pressure range, and a pressing member 22 that is disposed at the insertion path 13P side from the cover 24 to be pressed by the end of the fueling nozzle FZ. <P>COPYRIGHT: (C)2013,JPO&INPIT |
