To make the constitution over the entire part simpler and smaller by omitting a constitution, such as a traveling frame, traveling motor and motor for rotation of a waste decomposition treating device of a type to move an agitating machine in one direction on the circumference of the intermediate partition wall of a storage tank.
The outside wall 1A of the storage tank 1 is formed to an elliptic shape in plain view and the storage tank 1 is internally provided with the agitating machine 3 for advancing a truck by a deposition pressure at the time of scraping org. waste to a backward side. The inner traveling body 10 which travels along the guide 2B on the intermediate partition wall 1B of the storage tank 1 and an outer traveling body 11 which travels along the guide 2A on the outside wall 1A of the storage tank 1 are mounted at the truck of the agitating machine 3. When the inner traveling body 10 moves to the terminal part of the guide 2B on the intermediate partition wall 1B, the outer traveling body 11 is rotationally moved along the guide 2B on the outside wall 1A around the inner traveling bode 10 as a center of rotation.
