PROBLEM TO BE SOLVED: To provide an air pressure engine which utilizes wind and water force to form a low air pressure state in a cylinder, and utilizes compression air or the like generated by use of atmospheric pressure or wind and water force instead of using fuel for mechanisms in an internal combustion engine for actuating a piston. SOLUTION: Compressed air or a low air pressure state is formed by a compact hydraulic turbine, turbine, or underwater turbine without requiring a dam, and this is connected to an air pressure engine or air pressure turbine to be actuated. A supply air port 3 connected to outside air is provided at an upper part of a cylinder 1, an opening/closing device is provided at the supply air port 3, air sucking ports 5, 6 are provided at an upper and a lower parts of the cylinder 1, and an opening/closing device 4 is provided at the upper air sucking port 5. The upper and the lower air sucking ports 5, 6 and a vacuum device or an air sucking device 7 are connected to a mechanism to suck air in the cylinder 1 through the air sucking port to form a low air pressure state in the cylinder 1 for actuating a piston by air pressure of outside air, thereby a crank shaft is rotated.
