Abstract

PURPOSE:To easily open or close the cover of an underground structure by a method in which a cover is connected with a receiving frame by a rising and falling link rod, a coupling mechanism for the rod is provided for the receiving frame side, and a cover load-receiving seat is provided for the other end of the rod. CONSTITUTION:A bar-through hole 26 formed in the periphery of the side with the projected wall of a cover 2 is thrust with a bar to lift up the cover 2. A link rod 3 is uprisen on a link pin 4, and the weight of the cover 2 applies to the rod 3 to push down the rod 3. The rising and falling action of the rod 3 is restrained, and the projection 33 of the rod 3 is fit into the recession 15 of a receiving frame 1, and the rising state of rod 3 is secured. The bar is inserted into the other through hole and the cover 2 is turned, whereupon the opening in the frame 1 is further enlarged.
