<P>PROBLEM TO BE SOLVED: To provide a cool storage device type refrigerator that has a partition member adapted for partitioning a cool storage material housed in a regenerator, has a high dimensional accuracy to avoid formation of a gap between itself and an inner peripheral surface of the cool storage device, and can reduce manufacturing costs. <P>SOLUTION: The cool storage device type refrigerator includes a cool storage device 14 that stores cold generated in a cylinder 12 in a cool storage material 18a, 18b stored inside, and a partition member 40 for partitioning the cool storage material 18a, 18b. The partition member 40 includes a ring member 50 having an opening 51 formed in its center and whose outer peripheral surface is formed to fit over the inner peripheral surface of the cool storage device 14, and a stack 60 provided in such a way as to close the opening 51 and comprising filter members 61, 62 that do not allow the cool storage material 18a, 18b to pass through while allowing refrigerant gas to pass through and a reinforcing member 63 stacked with the filter members. A peripheral edge part 60a of the stack 60 is tightened as it is sandwiched by the ring member 50 from the front and rear along the direction of stacking of the stack 60. <P>COPYRIGHT: (C)2013,JPO&INPIT |
