Abstract
In a Stirling cycle engine, a regenerator has a bobbin, a resin film wound around the outer surface of the bobbin, and a sheath fitted around the outer surface of the resin film and having a slit formed vertically therein. The resin film has one end fixed on the outer surface of the bobbin, and has the other end led out through the slit and fixed to an end surface of the slit or to the outer surface of the sheath. The sheath is press-fitted on the inner surface of the enclosure. Working gas flows between different layers of the resin film. This reduces the loss of heat due to gas leakage and thereby improves the heat exchange efficiency in the regenerator.
