Claims

[Scope of utility model registration request]

A seal sliding contact member that seals between two fluids that exchange heat with a rotating cylindrical core at a position in contact with both sides of the core, a holder for the seal sliding contact member, and a space between the holder and the casing. A sealing device having a highly flexible and airtight membrane body is provided, and the seal sliding contact member is attached to the core together with the holder due to the pressure difference between the two fluids obtained through the membrane body. A rotary regenerative heat exchanger that is pressed into contact with the rotary regenerative heat exchanger, characterized in that the rotary regenerative heat exchanger has a ring plate that contacts the low-pressure side surface of the membrane body and transmits the pressure difference to the holder. .
