Disclosed is an opening and closing device including a closing member which is turned to an opening position by inserting a fuel-filling nozzle to open a fuel-filling aperture. The closing member includes a pair of flap bodies and a biasing device which positions each of the flap bodies in a closing position by a biasing force. The pair of flap bodies each includes a turning assembly portion as the center of the turning and an abutment portion with respect to the other flap body and is each configured to press its front surface portion against a hole edge portion of a passage hole of the fuel-filling nozzle by the biasing force and presses the abutment portion against the abutment portion of the other flap body. |
