A GM type displacer has an elastomer "O" ring at the warm end to absorb impact energy when the displacer reaches the bottom of the stroke before it would hit the cylinder end cap. When the displacer reaches the top of its stroke, before the displacer would hit the internal mechanism of the expander, another elastomer "O" ring absorbs the kinetic energy of the displacer. Both absorbers are at or near ambient temperature.

Even when compression stress is generated because a volume of a thermal insulation layer 2 is expanded due to oxidized by oxygen in the air, occurrence of cracks and fractures of the thermal insulation layer and a heating conductor 3 caused by the cracks are prevented by dispersing the compression stress. A pressure wave generator comprises a substrate 1, the thermal insulation layer 2 of porous material which is formed on a surface of the substrate 1 in thickness direction, and the heating conductor 3 of thin film formed on the thermal insulation layer 2, and generates pressure waves by heat exchange between the heating conductor 3 and a medium. When a thickness at the center of the thermal insulation layer 2 in width direction W is used as a reference thickness, and it is assumed that distribution of thickness of thermal insulation layer in the width direction is averaged with the reference thickness, porosity in an outer peripheral portion of the thermal insulation layer is made smaller than porosity in the center portion. By making the porosity in the outer peripheral portion of the thermal insulation layer 2 smaller, a number of immovable points on the outer periphery of the thermal insulation layer 2 restricted by the substrate 1 is increased and the positions of them are dispersed, so that the compression stress compressed in the outer peripheral portion of the thermal insulation layer 2 can be dispersed.
