    • A regenerator accumulates cooling generated by expansion of refrigerant gas, and the regenerator includes a regenerator material which is made of a nonmagnetic material, a regenerator material which is made of a magnetic material, a container which includes a high temperature end and a low temperature end, and which accommodates the regenerator material made of the nonmagnetic material at the high temperature end side and the regenerator material made of the magnetic material at the low temperature end side. The container further accommodates an insertion member which narrows a passage area of the refrigerant gas flowing to a region accommodating the refrigerator material made of the magnetic material so that the passage area of the low temperature end side is narrower compared to the passage area of the high temperature end side.
    • 再生器蓄积由制冷剂气体膨胀产生的冷却,再生器包括由非磁性材料制成的再生材料,由磁性材料制成的再生材料,包括高温端和低温端的容器 并且在高温端侧容纳由非磁性材料制成的再生材料和在低温端侧由磁性材料制成的再生器材料。 容器还容纳有插入构件,该插入构件使流过至由磁性材料制成的冰箱材料的区域流动的制冷剂气体的通道面积变窄,使得低温端侧的通道面积比高通道面积窄 温度端侧。
