PURPOSE: To roll or to turn a heavy object by means of a simple structure at a low cost in a small space without requiring any special power. CONSTITUTION: A rolling/turning device for a heavy object is provided with the first mounting face 6 and the second mounting face 7, which perpendicularly cross with each other in the horizontal direction or in the vertical direction and are integrated together, and is composed of a mounting part 5 which is rotated upward/downward in response to a position of the center of gravity of a heavy object W moving on the first mounting face 6, a fulcrum part 4 which is arranged on the first mounting face 6 and supports the mounting part 5 freely rotationally, and a roller 9 which is arranged on the first mounting face 6 and the second mounting face 7 and serves as a sliding part sliding the heavy object W in the specified direction. |
