PROBLEM TO BE SOLVED: To prevent abrasion of a rotary heat regenerative body and a sealing members while keeping sealing efficiency of a rotary regenerative heat exchanger which performs heat exchange between high-temperature fluid and low-temperature fluid and, further, to prevent abrasion of the rotary heat regenerative body and the sealing members even when the rotary heat regenerative body is deformed by heat. SOLUTION: A pair of sealing members 22, 23 are fitted on both sides of a rotary heat regenerative body 21 partitioning a low-temperature fluid path A and a high-temperature fluid path B. In between the sealing members 22, 23, clearance holding members 27, 28, with length in its axis direction larger than that of the rotary heat regenerative body 21, are arranged so as to keep a specified gap between each of the sealing members 22, 23 and the rotary heat regenerative body 21. |
