PROBLEM TO BE SOLVED: To prevent fire or disaster of a spreading fire caused by a leakage of refrigerant gas in a freezer device using inflammable refrigerant. SOLUTION: There is provided a freezer in which units constituting a freezing cycle and a pipe connecting these units and inflammable refrigerant is filled in the cycle. The units and the outer surface of the pipe are covered by a resilient member, thereby damping attenuation of vibration and shock applied from outside and restricting occurrence of cracks at the units and the pipe. Therefore, the leakage of refrigerant gas can be prevented.
