PROBLEM TO BE SOLVED: To provide a heat exchanger for a Stirling engine providing smooth and stable heat exchange with a heat transfer head. SOLUTION: In the Stirling engine 1, working gas is moved between a compression space 45 and an expansion space 46 by a piston 12 and a displacer 13. A high temperature side internal heat exchanger 42 and a low temperature side internal heat exchanger 43 arranged between the compression space 45 and the expansion space 46, and transferring heat exchanged with the working gas to a high temperature side heat transfer head 40 and a low temperature side heat transfer head 42 are both composed of the heat exchanger 100. The heat exchanger 100 is formed with a multiplicity of fins 102 extending in a center direction of a ring, in an inner face of a ring like base 101. A retaining ring 110 is pressed in a cylindrical space formed between tips of the fins 102. COPYRIGHT: (C)2007,JPO&INPIT
