The present invention relates to a combination structure of a shaft and a disk plate of a sludge drying apparatus, the combination structure of a shaft and a disk plate comprising a case; a shaft installed inside the case to be able to rotate; and a disk plate combined in multiple stages with the shaft. A hanging protrusion part, which protrudes outward from the shaft, and a concave groove part, which is indented inward, are formed alternately in a circumferential direction on the shaft, and a hollow part having a shape corresponding to the hanging protrusion part and the concave groove part is formed on the disk plate so that hollow part can engage the hanging protrusion part and the concave part. Therefore, the rotational force of the shaft can be stably transmitted to the disk plate. |
