Abstract

Disclosed is a stirling cooler, in which a cylinder(54) is fixedly installed in a case(50), a flange(55) is protruded perpendicularly from an outer surface of the cylinder(54) in a radial direction of the cylinder(54), a stair(51,51') on which the flange(55) is seated is installed in the case(50) in an axial direction of the cylinder(54), and a packing(70) is interposed between the stair(51,51') of the case(50) and the flange(55) of the cylinder(54), thereby preventing the packing(70) from influencing an axis of the cylinder(54) and thus maintaining the sealed state between the case(50) and the cylinder(54).
