PROBLEM TO BE SOLVED: To provide an air blowing structure of a Sterling refrigerator, capable of not only using air blown from a heat radiating air fan for air cooling for a heat radiator, but also using the air for defrosting of a cooler or air cooling for a Sterling refrigerator body. SOLUTION: The Sterling refrigerator 6 has a low temperature part 6c connected to the cooler 4 and a high temperature part 6d connected with the heat radiator 8, and makes the heat radiator 8 radiate heat by the blowing air of the heat radiating air fan. In the Sterling refrigerator 6, the low temperature part 6c and the heat radiator 8 are disposed forth and back along a flow of the blowing air of the heat radiating air fan, and the heat radiating air fan can be reversely rotated. Thereby, when driving the heat radiating air fan such that air is blown from the low temperature part 6c toward the heat radiator 8, cold air leaking from the low temperature part 6c is included in the blowing air to air-cool the heat radiator 8. When driving the heat radiating air fan such that air is blown from the heat radiator 8 toward the low temperature part 6c, air heated by the heat radiator 8 heats the low temperature part 6c.
