PROBLEM TO BE SOLVED: To improve the strength of a seal member for sealing the leakage of fluid between passages in a rotary heat storage type heat exchanger having a rotary heat storage body. SOLUTION: The rotary heat storage type heat exchanger, having a rotary heat storage body 21 for transferring the heat of high-temperature fluid to low-temperature fluid by moving the same alternately between a low-temperature fluid passage A and a high-temperature fluid passage B by turning the heat storage body 2, is provided with a pair of seal members 22, 23, arranged so as to cover both end surfaces of the opening of a through hole 21 in the rotary heat storage body 21 respectively and provided with a multitude of through holes 22a, 23a formed thereon, and flow passage defining units 24, 25 for defining the flow passage of the low-temperature fluid and the flow passage of the high-temperature fluid, which are passed through the rotary heat storage body 21. |
