の開閉移動工具。 A long lever is provided with the lower part fixed perpendicularly to the lever at a position biased to one side of the lever, and a small wheel is mounted on a short shaft supporting piece that protrudes to one side of the lower end of the lever. A support rod is attached between the middle part of the lever rod and near the end of the lever rod on the side opposite to the side where the lever rod is fixed, and the lever is inserted into each keyhole of the manhole iron cover and engaged with the lever rod. Two key rod supports, each provided with a key rod to be obtained, are rotatably inserted into the shaft rod, and the two key rod supports are provided at both ends of the rod so as to protrude in the same direction as the protruding direction of the small wheel shaft support piece. A large wheel is pivotally supported on a shaft support piece that is much longer than a small wheel shaft support piece, and the large wheel touches the ground when the iron cover is slightly raised by tilting the lever lever using the small wheel as a fulcrum. A tool for opening and closing a manhole iron cover, which is characterized by being designed to act as a fulcrum for connecting.
