困難な欠点が存在した。(Prior technology) When opening the lid of a conventional iron lid to go up and down into the pine hole, the lid is rotated 180 degrees and the back side of the lid is placed upwards on the ground surface. When placed,
Next, when the lid is closed, the lid is placed in close contact with the ground surface, so there is no place to hold it on the outer periphery of the lid, and there is no place to hold it on the back of the lid, so it is difficult to handle heavy objects. There was a drawback that it was difficult to lift and move a certain lid part to close it.

いた。 The handle of the manhole frame cover disclosed in Japanese Utility Model Application Publication No. 54-89852 has a structure that is attached to the inner surface of the cover in the shape of a torii gate. However, since both ends of this handle are attached to short supports and are spaced apart from the lid, the lid is not reinforced and is fragile, making it impossible to operate the handle with a key. Also, if you have a small iron lid, you can lift it up and down by grasping the handle by hand, but with a large and heavy iron lid,
Since it was not possible to raise, lower, or move the structure manually, the support frame and iron lid were not connected using hinges, but were assembled independently. When operating the iron lid, wire ropes and cranes were used to open, close, and move it.
