<P>PROBLEM TO BE SOLVED: To provide an apparatus for opening and closing a horizontal lid wherein there exists no possibility of generating a gap between the outside face of a lid plate opened upward after lifted up and rotated, and the inside face of a frame surrounding the lid plate. <P>SOLUTION: A fitting plate fixed on the underside of the lid plate, a main link body pivoted on the fitting plate, a sub-link body pivoted below the main link body on the fitting plate, and a supporting frame base for supporting fixing shafts for the main link body and the sub-link body, are provided. A fixed shaft point for the main link body is positioned approximately on the same plane as that for a movable shaft point or a little lower under a condition where the lid plate is closed, and a fixed shaft point of the sub-link body is positioned lower than the fixed shaft point of the main link body. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
