Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a cold storage type refrigeration machine capable of performing a cold energy storage process in low cost and high efficiency.SOLUTION: A cold storage type refrigeration machine 1A includes a second stage displacer 20 filled with a cold storage material storing cold energy from a refrigerant gas. The second stage displacer 20 is divided into a central section 21 in which flow passage resistance of the refrigerant gas is small and a peripheral section 22 in which the flow passage resistance is large in its cross-section direction. A magnetic cold storage material 42 having a high specific heat is provided in the central section 21, and a non-magnetic cold storage material 40 formed of non-magnetic material is provided in the peripheral section 22.
