The upper part has, at its outer peripheral surface, a male thread to be engaged with a charging port, and also has, at its inner peripheral surface, a thread fitting knurling mark at its inner peripheral surface. The lower part has a sealing plate at its inner lower part and a hook ring with a charging port at its lower end outer peripheral surface. The charging port of the receptacle comprises the upper part and the lower part. The upper part has a female thread to be engaged with the sealing cap at its inner peripheral surface. The lower part is provided with an abutting ring at its inside lower inner peripheral surface where a lower surface of a step at the lower end of middle part of the sealing cap is abutted against the upper surface. A plurality of hook plates are protruded in a peripheral equal spacing at the inner peripheral surface of the abutting ring through a hinge. When the sealing cap is threadably engaged within the charging port of the receptacle, the hook plates are bent downward by the lower extremity end of the sealing cap, and then the hook ring at the lower part of the sealing cap is engaged with the extremity end of the hook plate of the abutting ring of the charging port of the receptacle. <P>COPYRIGHT: (C)2007,JPO&INPIT |
