するおそれがある。However, the piping structure in which the refrigerant tube 11 is wound in a coil shape as described above has the following problems in terms of supporting and handling the piping. That is, if the pipe portion wound in a coil shape of the refrigerant pipe is left free inside the base 4, the refrigerant pipe 11 becomes improper due to vibration applied when the showcase is shipped from the factory to the location. There is a possibility that the copper pipe is cracked or broken by repeatedly bending the pipe in a regular manner.

It is. Also, when the condensing unit 10 of the refrigerator drawn out from the base 4 is stored in the base during maintenance at the location, the coil part of the refrigerant pipe 11 may be entangled unless the coil part of the refrigerant pipe 11 is properly removed. As a result, when the condensing unit is pulled out next time, an excessive bending force may be applied to the refrigerant pipe, and the copper pipe may be broken.
