PROBLEM TO BE SOLVED: To provide a rotor structure for a rotary heat exchanger in which heat can be exchanged in a temperature zone in which the quantity of exhaust smoke can be suppressed and which is required for superheated steam by solving a problem on corrosion or embrittlement of metallic materials in a rotary supporting part and a driving part of a rotor of a rotary heat storage body occurring when steam is heated by using high temperature gas generated through waste treatment and a problem of damage of the rotary heat storage body due to thermal strain. SOLUTION: In this rotor structure of a rotary heat exchanger 1 having a rotary heat storage section 3 of a heat storage material 30 that has a fluid channel 31 for heat exchange and is rotatably supported by a shaft 2, a cooling passage is formed in the shaft 2, plural jackets 22 are provided radially from the shaft 2, the insides of the jackets 22 are communicated with the cooling passage, the heat storage material 30 is held by the jackets 22, and thus the rotary heat storage section 3 is formed.
