FUEL TANK OPENING-CLOSING DEVICE
First Claim
1. A fuel tank opening-closing device that opens and closes a fuel passage for supplying fuel discharged by a fueling nozzle to a fuel tank, the fuel tank opening-closing device comprising:
- a tank opening forming member that includes (i) the fuel passage and (ii) a first opening forming member, disposed in the fuel passage and having a first opening, anda first flap valve mechanism having (i) a first opening-closing member for opening and closing the first opening, and (ii) a first shaft rotatably supporting an end part of the first opening-closing member on the first opening forming member,wherein the first opening-closing member includes;
a pressing part that has (i) a push face pressed by an end of the fueling nozzle and (ii) a restriction wall forming a restriction region that restricts so as to selectively allow insertion of a specific outer form of the fueling nozzle, the restriction wall being configured to be erected along an outer edge of the push face and to enclose at least a portion of the push face, anda guide member that is formed and inclined to broaden a nozzle guiding space from an upper part of the restriction wall toward an insertion direction of the fueling nozzle, the guide member being configured to guide the end of the fueling nozzle to the restriction region.

Abstract
The fuel tank opening-closing member has a tank opening forming member having a first opening forming member which has a first opening, and a first flap valve mechanism having a first opening-closing member for opening and closing the first opening, and a first shaft for rotatably supporting one end part of the first opening-closing member. The first opening-closing member is equipped with a pressing part having a push face pressed by the tip of the fueling nozzle, and a restriction wall forming a restriction region which restricts so as to allow insertion only of specified fueling nozzle external shapes established along the outer edge of the push face, enclosing at least a portion of the push face, and a guide member which is formed tilted toward the top part of the restriction wall, and leads the tip of the fueling nozzle to the restriction region.
