A heat pump has a hot displacer and a cold displacer disposed opposite to each other in a state wherein the two displacers are guided by two guide projections so as to form two gas springs, respectively, and the two displacers continue to move reciprocally due to change of pressure of working gas without any outer mechanical driving force.
