PROBLEM TO BE SOLVED: To inexpensively manufacture a long ice making machine by adopting a rational construction utilizing buoyancy applied from a liquid to be cooled. SOLUTION: This ice making machine is adapted such that a refrigerant space is provided on an outer peripheral surface of a first cylinder on the internal peripheral surface of which an ice production surface is formed, in which space a low temperature refrigerant flows, and a rotary shaft 5 is rotatably provided in the first cylinder around a horizontal shaft core corresponding to the center of the cylinder, and further an ice scraping member is mounted on the rotary shaft 5. Further, a liquid to be cooled is supplied into the first cylinder, and an ice containing fluid is taken out from the first cylinder. In this case, the rotary shaft 5 is constructed by coupling in the direction of the rotary shaft core a plurality of split shaft members 11 each of which includes a cutout 15 on the side of longitudinal one end and a protrusion 16 on the side of the other end. Further, the split shaft member 11 is constructed with a hollow cylinder having a closed space S sufficient to receive buoyance corresponding to the weight of itself in the state where the member 11 is mounted in the cylinder and dipped in the liquid from the liquid.
