ネを組込む構成とするものである。A technical means for solving the above-mentioned problem is to form a U-shaped knurled notch in the periphery of a lid which can be opened and closed as viewed from above to engage and disengage a lid opening tool. ,
At the lower part of the notch, a vertical side wall and a seat connecting it are formed along the parallel part, and a large through hole at the center of the seat and a long hole extending downward on both sides of the side wall. A closing plate structure formed of a rod-shaped body having a closing plate integrally fitted with the cutout portion at its head, and the closing plate structure is formed in a through hole of a seat of the lid. Slidably up and down
Further, a pin is driven into the rod by penetrating the through hole in the side wall, and a compression coil spring is incorporated between the pin and the seat.

が容易となるものである。According to the closing plate structure for an iron lid having the above-described structure, the rod-shaped member is inserted into the through hole of the seat, and the inserted pin is vertically movable using the elongated hole of the side wall as a guide. By sliding the rod-shaped body through it, and incorporating a compression coil spring between the pin and the seat, the closing plate structure is constantly urged upward to close the U-shaped notch, and when the lid is opened, When the cover opening tool is pressed from above, the compression coil spring is contracted to lower the closing plate structure, and a sufficient space is formed in the stiffening portion to facilitate the stiffening opening operation.
