Abstract
A Stirling cryocooler includes a displacer having a displacer base portion disposed on a center axis and a displacer tip portion aligned along the center axis, extending from the displacer base portion to a working-gas expansion space, and a regenerator disposed surrounding the displacer tip portion such as to guide reciprocating travel of the displacer along the center axis. The displacer tip portion includes a plurality of platelike components arranged along the center axis, with each of the plurality of platelike components being furnished with a component side surface defining a portion of the outer surface of the displacer tip portion. The plurality of platelike components form working gas layers between pairs of adjoining components, and/or are formed of a synthetic resin material.
